Gleanings of the Week Ending December 16, 2023

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

The World’s Oldest Living Land Animal, a Tortoise Named Jonathan, Turns 191 – He lives on St. Helena (the small island in the Atlantic where Napoleon Bonaparte died). He has lost his sense of smell and is virtually blind from cataracts, but his appetite is good!

Extreme Weather Inflicting Higher Costs but Fewer Deaths – Improved warning systems have been key to reducing the loss of life from cyclones, floods, and fires. Kudos to the governments that have implemented them. Hopefully Africa will be able to increase their weather stations and early warning systems…catch up with other parts of the world.

25 Incredible Photos in the Running for Wildlife Photographer of the Year People’s Choice Award – Which one is your favorite? Mine is the ‘happy turtle’ with the dragonfly on his nose.

Here’s What Can Cause Itchiness – Interesting….Staphylococcus aureus could the culprit for some people with eczema….maybe resulting in effective treatment/relief.

Nēnē: The Recovery of the Hawaiian Goose - Today, there are some 3,200 nēnē in the wild. By almost any measure, it’s a stunning conservation success. The threats of habitat fragmentation and invasive predators are omnipresent, so the birds need constant attention from conservationists and wildlife managers. Currently, there are populations on Hawai’i, Kaua’i, Maui and Molokai.

Secrets of the Catacombs - A subterranean necropolis offers archaeologists a rare glimpse of Rome’s early Jewish community. More than 60 catacombs, amounting to hundreds of miles of passages, have been identified beneath the Rome; they were the common approach to burial from the second through fifth century AD. Villa Torlonia, discovered in 1919, was the sixth, and so far the last, Jewish catacomb to be found in Rome and is one of just two accessible today. The catacomb’s passageways are lined with nearly 4,000 shelves carved into the walls to hold the dead. Many of the names of the deceased are still visible, generally painted on or carved into stucco used to seal the graves, along with blessings to rest in peace and other inscriptions. In a few places, the catacomb’s narrow passageways open into atriums where colorful frescoes decorate the vaulted ceilings and many of the arched recesses. In addition to menorahs, these frescoes feature Jewish motifs such as a holy ark to house Torah scrolls; shofars, ram’s-horn trumpets blown on religious holidays; and lulavs, palm branches waved during the festival of Sukkot, which celebrates the harvest season. There are also geometric designs and illustrations of peacocks, roosters, flowers, and fruit trees, possibly meant to depict paradise.

Wild Kiwis Born Near New Zealand’s Capital for the First Time in More Than 150 Years – Another bird conservation success in this week’s gleanings!

New Thoughts on Neanderthal Hunters - Neanderthals may have gathered in large groups to hunt and consume an elephant, and they may also have been able to preserve and store such a large amount of food.

Rare, White Alligator Born at Florida Wildlife Park - The leucistic reptile was born at Gatorland, a 110-acre park located south of downtown Orlando. The new gators are descendants of a group of leucistic alligators found in a Louisiana swamp in 1987. Since 2008, three of those Louisiana gators have been living at Gatorland.

500 year old hand grenades (China) – 59 spherical projectiles discovered in a storeroom along the Great Wall near the popular Badaling section. They were made of stone and had been drilled with holes that could be filled with gunpowder and sealed, creating an explosive effect when hurled at an enemy.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Water Worker Stumbles Upon 2,500-Year-Old Gold Necklaces in Spain – Celtic gold….from before the Roman Empire ruled the Iberian Peninsula.

Canopy gaps help eastern hemlock outlast invasive insect – Hemlock wooly adelgid killed most of the hemlocks in the part of Maryland where I lived previously. Perhaps part of the reason so many died was that they were in forests where there were too few gaps in the canopy around them.

Germany to Surpass 50 Percent Renewable Power This Year – Good milestone but evidently Germany is still not on pace to reach its goal of 80 percent renewable power by 2030.

The surprising origin of a deadly hospital infection - The burden of C. diff infection may be less a matter of hospital transmission and more a result of characteristics associated with the patients themselves (i.e. patients that are already colonized with C. diff were at greater risk to transition to infection). However, it is still unknown what triggers the transition from C. diff hanging out in the gut to the organism causing diarrhea and the other complications resulting from infection.

Meet the Bison: North America’s Most Famous Mammal – Lots of info on bison…their history of almost being hunted to extinction.

The secret world of rhododendrons: a plant more ancient than the Himalayas that inspired fables and stories around the world - There are around 1000 species in total, and modern DNA-based work confirms that all “azaleas” are in fact species of rhododendron.

A Sign of Things to Come? After Last Ice Age, Europe Cooled as the Planet Warmed - More than 8,000 years ago, as the planet thawed following the end of the last ice age, Northern Europe abruptly cooled. New research reveals that Arctic ice melt weakened a critical ocean current, leaving Europe in the cold, a finding with important implications for future climate change.

Fiber from crustaceans, insects, mushrooms promotes digestion – Chitin (from insect exoskeletons and mushrooms) activates the immune system and benefits metabolism. Insects are not on my menu….but I could eat mushrooms more frequently. The researchers plan to follow up to determine whether chitin could be added to human diets to help control obesity.

Review of over 70 years of menopause science highlights research gaps and calls for individualized treatment - Less than 15% of women receive effective treatment for their symptoms. Socio-economic factors such as lower quality of life and the potential negative impact of menopausal symptoms on a woman's work performance aren't often acknowledged. Therapy should be individualized depending on age and health risks, recognizing that health risks may increase with age.

California and Florida grew quickly on the promise of perfect climates in the 1900s – today, they lead the country in climate change risks - In California, home owners now face dangerous heat waves, extended droughts that threaten the water supply, and uncontrollable wildfires. In Florida, sea level rise is worsening the risks of high-tide flooding and storm surge from hurricanes, in addition to turning up the thermostat on already humid heat. Global warming has put both Florida and California at the top of the list of states most at risk from climate change. These futures bring into question how historic visions of economic growth and the sun-kissed good life that California and Florida have promised can be reconciled with climates that are no longer always genial or sustainable.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

As the Mississippi Swerves, Can We Let Nature Regain Control? - After the lower Mississippi began pouring through and enlarging Neptune Pass in 2019, sediment began flowing into a sand-and-silt-starved Delta Bay. Now the Army Corps of Engineers — breaking with tradition — is considering letting at least part of the river have its way…..a change from always ‘filling the breach’ strategy of years past that has had positive economic impacts but caused environmental problems. According to the U.S. Geological Survey, since 1932, more than 2,000 square miles of land in the Mississippi Delta have disappeared under water.

Babcock Ranch: Florida's first hurricane-proof town - When Hurricane Ian made landfall on the southwest Florida coast, it brought 150 mph winds, 17 inches of rain within 24 hours, and storm surges of up to 18 ft. It was the costliest hurricane in Florida's history, causing more than $112 billion  in damage – and at least 150 deaths. Babcock Ranch is an 18,000-acre development that was sitting in the eye of the storm on the southwest of the state just north of Fort Myers. Built to withstand powerful storms, the town came out relatively unscathed. Is this type of development going to be the only kind economically viable for states like Florida in the future?

Year-round school: Difference-maker or waste of time? – No conclusion in this article….evidently there is renewed interest in the idea in the Southeast. But – the concept is not what most people probably assume. The implementation does not involve more days in school for students and often makes childcare more difficult!

What Are Heat Pump Air Conditioners? - Modern heat pumps are superefficient and can deliver heat down to -15 degrees Fahrenheit…but I had to look to find that they can deliver cool air up to 115 degrees which should have been in the article since it was about air conditioning!

Controversial dwarfism drugs spur growth — but do they improve health? – Hard choices.

Microplastics infiltrate all systems of body, cause behavioral changes – Especially in older mice…behaviors akin to dementia in humans. The changes became more profound in older animals. The microplastics in the study were delivered orally via drinking water…and not in high doses.  It’s scary to think about how microplastics might be impacting humans too.

Can California Cropland Be Repurposed for Community Solar? – Evidently the current farming practices are not sustainable, and some farmland needs to be retired. The idea is that the already disturbed land could be repurposed for new community solar projects. I wondered where the food we now are getting from California will be grown in the future…how robust is the US food production system?

TB research shows a good diet can cut infections by nearly 50% - Improved nutrition in family members of patients in India with lung TB reduced all forms of TB by nearly 40%, and infectious TB by nearly 50%. And…for the patients: An early weight gain in the first two months was associated with 60% lower risk of TB mortality. The other benefits were higher treatment success and better weight gain. During the six-month follow-up period, a remarkable treatment success rate of 94% was achieved.

Top 10 Things You Didn’t Know About Wind Power – How many of these 10 did you know already? I knew 4 of the 10…and knew a little about several others. It’s good to see the progress being made. Kudos to Iowa and South Dakota where over 50% of their electricity generation is from wind energy.

Soils forming on the branches of trees are an overlooked forest habitat – This was a study of a tropical forest in Costa Rica, but it reminded me of a tree along a field trip hiking route in Maryland that I always pointed out to students. It was an old maple that had an indention in its trunk that contained soil about 6 feet above the base of the tree. The tree had grown some roots into that soil and there was moss there. Spider webs filled in. Once we found a shed snakeskin hanging from the area!

Fort Pickens

We visited the Fort Pickens area of Gulf Islands National Seashore twice during our visit to Pensacola. We looked at the fishing pier area first --- searching for birds. Brown pelicans were searching for breakfast…not minding the fishermen on the pier nearby. They are probably in the area year-round.

Some of the structures were derelict. Water and salt are hard on concrete.

Several immature red-breasted mergansers were also finding food in the surf. They might continue north even though they are not breeding this year.

Willets and a great blue heron were wading in the surf.

Immature Bonaparte’s Gulls were on the beach…resting.

Looking toward the mainland from the Fort (on a barrier island), a lighthouse is visible. It is on the Naval Air Station which limits tours to people with military IDs.

We heard and saw small birds in the grass near the historical buildings/discovery center. Looking closer we saw that they were blue grosbeaks! They were probably refueling before they continued their migration northward.

Two osprey were building a nest at the top of a chimney nearby.

On the drive away from Fort Pickens after our first visit, we spotted a mature bald eagle in a tall pine. I’d spotted a large nest as we had driven toward the Fort….so we were looking closely for the bird!

We joined a ranger-led walking tour of the fort to learn a little about its history. Fort Pickens was built after the War of 1812 and before the Civil War….built with slave labor (many were skilled laborers specializing in brick structures).  It was the largest brick structure on the Gulf of Mexico after it was finished and was a deterrent to conflict for a time. Its only active use was during the Civil War; it stayed in Union hands for the duration. Much of the brickwork has survived. The Fort was modified for other purposes over the years…with part of the structure used to store land mines! It served as a prison for Geronimo before he was sent to Fort Sill (in Oklahoma). Today – plants grow on the structure and in areas that were once busy with military preparations. The tour was a bit long (1.5 hours); I enjoyed the first hour but was tired for the last half hour.

Vacation to Pensacola, FL

Our trip from home (Nixa, MO) to Pensacola, FL in April was our most substantial post-pandemic vacation…three days in a place we had not visited before bracketed by long driving days. We thought we were used to long drives because of all the trips between Maryland and Missouri last spring associated with our move, but the non-Interstate roads and long rural expanses going to Pensacola made it a harder drive. The only rest stops were welcome centers when we crossed state lines; we made stops at fast food places and gas stations but sometimes they were further apart than we prefer.

It was scenic…with roadcuts and forests, rivers and fields. In Arkansas there seemed to be a lot of farmers plowing…kicking up dust; I’d seen so many no-till fields in recent years that the plowing struck me as a retro strategy (and one that obviously depleted topsoil). In Mississippi, we noticed a community with blue roofs; as we got closer, we realized the blue was from tarps and there were big stacks of fallen trees nearby; a police car monitored the comings and goings from the community. By the time we got to Alabama we were tired…glad we were getting close to our destination.

Our previous visits to Florida had been primarily to the Atlantic coast and Orlando. Pensacola had a deep South vibe. The military presence (current and historical) also influenced our perception of the area. We wanted to see the Gulf Islands National Seashore and several other natural areas – for birds and plants. We stayed at a hotel with a small kitchen…took advantage of the breakfast they provided and snacked in our room in the evening after having a substantial lunch while we were out and about during the day. There was a magnolia blooming near our room.

Overall – the trip was OK but not spectacular. We learned about ourselves as much as about the area:

  • A google maps time of 11.5-12 hours is too much for us to do in a day – particularly if the route is not mostly Interstates.

  • Spring is a great time for road trips….fall will be too. Summer is often too hot and winter weather can be problematic.

  • Birding festivals give us the discipline to get up and out early…into places that are harder to find on our own in an unfamiliar area of the country. We’ll register for a festival to structure our next trip.

I’ll be posting about our Pensacola vacation in the upcoming days….stay tuned.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Climate change threatens spring wildflowers by speeding up the time when trees leaf out above them – Evidently the trees and wildflowers in eastern North America are the ones getting the most out of sync.

The mystery of Alice in Wonderland syndrome (AIWS) – AIWS (or Todd’s syndrome) affects the way people perceive the world around them and can distort the way they experience their own bodies and the space it occupies. There are 40 types of visual distortions that characteristic of the syndrome. It was formally described as a distinct syndrome in 1955. Up to 30% of adolescents reported mild or transient experiences. Cough medicines and illicit hallucinogenic substances are also known to trigger it.  Sometimes medical conditions like strokes or brain tumors can cause the syndrome as can infections.

Chinook salmon fishing season canceled off coasts of Oregon, California – Dwindling numbers of Chinook salmon in the states’ largest rivers following years of drought.

In Florida, an invasive snail is helping save an endangered bird – We heard about this during a birding trip to central Florida pre-pandemic. It probably is one of the few examples when an invasive species has produced a positive outcome.

Garbage to Guts: The Slow-Churn of Plastic Waste – Lots of microplastics in the world…and they are in our food chain. Ongoing exposure decreases beneficial gut bacteria and increases pathogenic species. A lot more research needs to be done since, right now, we don’t know very much about impacts of microplastics – not just to the overall environment but to our own bodies.

 With Heat from Heat Pumps, US Energy Requirements Could Plummet By 60% - Thinking about heat….and the ‘rejected energy’ (mostly heat) in our current energy consumption. The idea is to use heat pumps to dramatically reduce ‘rejected energy’ in future energy consumption.

Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms – Evidently the December 2021 - January 2022 breeding season for south polar skua, Antarctic petrel, and snow petrel was so disrupted that there were almost no young produced.

Why don’t humans have fur – Interesting…but we really don’t know. The genetic research associated with the question could have practical application for people that need to stimulate hair growth (like after chemotherapy or balding).

2021 Was A Very Good Year for Nesting Wading Birds In The Everglades – Hurray! Some good happening in the Everglades. There are so many stories about the impact of invasive species (like Burmese pythons) that this is welcome news.

Meet the sargassum belt, a 5,000-mile-long snake of seaweed circling Florida - In the open sea, sargassum can soak up carbon dioxide and serve as a critical habitat for fish, crabs, shrimp, turtles, and birds…all positive. But when sargassum gets close to shore it can smother coral reefs, alter the water’s pH…and then onshore it begins to rot within 24 hours releasing irritants like hydrogen sulfide which smells like rotten eggs or manure and can cause respiratory problems. And it often contains significant amounts of arsenic so not a great addition to a compost pile. The mass of sargassum has been increasing since 2011 --- probably in response to elevated nutrients (runoff from fertilizer, burning biomass, increasing wastewater from cities, etc.) we have released into the ocean. Sargassum has come ashore in Yucatan and Key West recently.

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Arctic river channels changing due to climate change – The prediction was that Arctic rivers would be destabilized by atmospheric warming…that thawing permafrost would weaken riverbanks causing faster channel changes. Using 50 years of satellite data for areas of Alaska, the Yukon and Northwest Territories (which is experiencing the sharpest atmospheric warming due to climate change), researchers have discovered that greening of the area due to warmer temperatures has caused the riverbanks to be more stable…decreasing the sideways migration of river channels by 20% in the Western Arctic!

US Energy Storage Made Record Gains Last Year – A good new story! Something I didn’t know too: “they US remains the largest demand market for energy storage in the world.”

A pool at Yellowstone is a thumping thermometer – The water vibrates…the ground shakes. The intervals between reflects the amount of energy heating the pool at the bottom and how much heat is being lost from the surface.

Awe-Inspiring Videos Show Powerful Ospreys Diving in Pursuit of Prey – Photographer Mark Smith’s Osprey pictures/videos. I saw this post and the photographer was mentioned in the composition class I was views on the same day!

Crocodiles are uniquely protected against fungal infections. This might one day help human medicine too – Crocodiles have unique defensins (components of white blood cells and mucous membranes) that are inactive at neutral pH (as in the blood) but are active in sites of infection where the pH is lower (i.e. acidic). There is a lot more research and trials between this finding and application to humans.

'All work, no independent play' cause of children's declining mental health – The reduction has happened over decades. I was surprised by the quantification: “Between 1950 and 2010, the average length of the school year in the U.S. increased by five weeks. Homework, which was once rare or nonexistent in elementary school, is now common even in kindergarten. Moreover, by 2014, the average time spent in recess (including any recess associated with the lunch period) for elementary schools was just 26.9 minutes a day, and some schools had no recess at all.”

Mesa Verde National Park has plan to save Spruce Tree House – The area has been closed since 2015 because of concerns that layers of sandstone could peel away from the arch at any time. There is a lot of work involved and the plan is current open for public comment. When we visited Mesa Verde back in 1980, it was still open to visitors. Mesa Verde is still a National Park I would like to revisit.

Toxic red tide is back in Florida – Another deterrent to making a road trip to Florida….although it appears that right now there are no red tides in the panhandle…which would be the closest destination for us…I’m thinking maybe Pensacola.

Here Are the Incredible Winners of the 2022 World Nature Photography Awards – A little eye-candy for this week. ‘Fungus Horizon’ is my favorite.

Heat pumps for every home – A good introduction to heat pumps. I want a variable speed heat pump that uses the existing ducts in my house!

Photographer Creates Mesmerizing Flight Trails of Winged Creatures as a Meditation on Time – Action in the air (composite images).

The crab invading the Mediterranean Sea – The blue crab is native to the Indo-Pacific but reached the Mediterranean Sea in 1898…about a decade after the Suez Canal opened. With temperatures in the Mediterranean rising with climate change, more the crab larvae are reaching adulthood. Now the Tunisians are trapping and processing crabs for export. Other places in the Mediterranean are also harvesting and processing invasive species: Cyprus has local restaurants serving lionfish and jewelry/artwork is created from their soft colorful fins. Rabbitfish have also become a commercial fish. But will these measures be enough to rebalance the ecosystems and improve biodiversity?

Where did pigeons come from? – A bird that we see frequently….that humans have taken around the world…and it likes to stay near us!

Understanding the new Federal tax credit for electric cars – Why does it always have to be complicated?

Is dark chocolate really good for you? – Of course! I like my high % cocoa squares first thing in the morning…my perfect 1st breakfast.

The dangers of working in hot weather – Glad to see some attention on this…and a sharing of practices that can help while still getting work done. With the high level of employment (and often challenges hiring new people), businesses should have an elevated interest in keeping their workers healthy and productive.

 Home solar + storage will get a boost from the recent climate bill, claims Bloomberg – Hurray!

Banana peels make sugar cookies better for you – Ok – so maybe I should never put banana peels into the compost. I’d rather use them directly in recipes like Banana Peel Cake rather than making them into flour. I think I’ll start washing them and putting them in the freezer when I eat the fruit….process them as I need them for baking!

Meet the world’s largest land crab – And also learn a bit about Palmyra Atoll.

Is the river of grass really a river? – A little history…and discussion of what makes The Everglades a river (an unusual one!).

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Monkeying Around with Venom – Hadn’t heard about ‘Snake Detection Theory’ before; it is the idea that snakes have exerted a selection pressure on the origin of primates’ visual systems, a trait that sets primates apart from other mammals. This paper is some recent research that supports the theory.  A condensed description of the research paper is found here.

Why climate lawsuits are surging - Lawsuits are becoming tool to force change…in conjunction with activism, policy and science. There have been some successful lawsuits…and more in the pipeline. Sometimes the suit is about better enforcement of environmental laws…and sometimes it is about climate protection for future generations becoming a constitutional issue.

Florida to Feed Starving Manatees, as Pollution Shrinks Food Supplies – Florida farm runoff caused alga blooms that cut the penetration of sunlight into the water so much that it killed the seagrass that manatees eat…and there have already been more than 1,000 that have starved. It is estimated that there are about 8,000 manatees remaining in Florida waters. It is unclear that the seagrass can be restored.

Top 25 birds of the week: December 2021 – Enjoying bird photographs!

How volcanic eruptions helped the ancestral Puebloan culture flourish – Response of people to the stresses of abrupt climate change evidently resulted in larger population centers…universal pottery making and turkey cultivation…more sedentary living…increasing social inequity.

Major Contract Awarded To Rehabilitate Section Of George Washington Memorial Parkway – The parkway is along the Potomac River between Great Falls and Mount Vernon. It was one of the first beautiful and history things we discovered when we moved to the area in 1983…and long overdo for renovation. Parts of it carry a lot of daily commuter traffic in Northern Virginia.

The impact of drugs on gut microbes is greater than we thought – Most people are aware of the impact of antibiotics, but other drugs impact the gut microbes too…and some of those drugs are treating chronic conditions so are taken for years. It appears this study was mostly about methodology to tease out the impact of drugs vs the underlying disease….much more work still to be done before concrete recommendations can be made.

The race to make vaccines for a dangerous respiratory virus – RSV (Respiratory Syncytial Virus). There are currently 4 candidate vaccines and one monoclonal antibody treatment that are in last-stage trials. It appears we are at the cusp of much faster vaccine development times because of what happened to develop the COVID-19 vaccines.

The tomatoes at the forefront of a food revolution – The idea is to use Crispr modification to sustain the productivity of the tomato crop as the climate changes.

Chronic exposure to air pollution may increase risks for ICU admission or death among COVID-19 patients, study finds – Sometimes it is hard to separate the role of the environment on health disparities. This study analyzed 6,500 COVID-19 patients admitted to 7 New York City hospitals.

How your phone battery creates striking alien landscapes – Lithium….needed for batteries that are needed for so many things (not just phone batteries).

Why do house finches love your hanging plants? – These birds are frequent visitors to our feeder. Based on the crowd we are seeing now – they’ve had a very successful breeding season…lots of young birds.

Ultraprocessed foods now comprise 2/3 of calories in children and teen diets – This article prompted me to look at what ultraprocessed foods I am eating…and making some changes. I am keeping the 1st breakfast that includes 90 calories of dark chocolate…but all the other ultraprocessed foods are going to become occasional or rare in my diet.

Tracking the Restoration of the River of Grass – An interview with Eric Eikenberg, President of the Everglades Foundation. There is a lot of work coming to fruition this decade in restoration of the Everglades…some positive news from Florida. It was an encouraging article but after reading the whole thing, it still seems to me that climate change will be a continuing disaster for Florida.

Red Tide Rages Along Florida’s Gulf Coast – On a more pessimistic note about the environment in Florida right now…

Top 25 birds of the week: August 2021 – Birds….so many different kinds to see.

Crawling with crickets: the insect swarm in the western US – Mormon Crickets (really katydids) have population crescendos in 3 of every 10 years in the west. The occurrences are patchy but damaging for some crops.

Music in the American Wild – I watched the Missouri Music at 200 webinar this week and am now looking at more of the concert videos from the ensemble. I’ll post the “Missouri Music at 200” webinar video address (when it is available on YouTube). Of course – live performances would be even better. I enjoyed the Hawaii 2020 project videos already…lots of good views of the island (particularly birds and volcanos!).

The ancient Persian way to keep cool – We’ve had quite a few heat advisory days recently…will probably have an increasing number every summer. The world will need to implement the most efficient strategies available to keep people cool.

Camera Trapping As Mainstream Nature Activity – Little cameras in the wild…they are probably less obtrusive than a human being in the place all the time…but not totally benign in every place.

Climate Change Responsible for Recent Decline of Eastern Monarch Butterflies – I know that the milkweed in my Maryland yard is not as healthy looking and I don’t see as many butterflies as I did in the 1990s…it’s a sad trend.

Top 25 birds of the week: July 2021 and Perching – A special treat – two collections of bird photographs in this gleanings post!

The parenting penalties faced by scientist mothers – There are no single or quick ‘fixes’ – moving forward requires thoughtful approaches. The status quo is not acceptable or sustainable!

True Grit: Adventures in Red-Cockaded Woodpecker Research – My husband and I saw red-cockaded woodpeckers in Florida during a birding festival field trip…so I tend to look at articles that appear in my news feed about them.

Florida Breaks Annual Manatee Death Record In First 6 Months Of 2021 – Florida seems to be a less appealing place to visit these days. Manatees were an animal my husband and I always wanted to see there and now they are starving to death because the seagrass (their food) is dead or dying in polluted waters. Other animals are probably impacted as well.

Chaco Culture National Historical Park: Hard To Reach, Filled With The Unexpected – I’ve only been to Chaco Canyon once….in the spring when it wasn’t overly hot. There were not many people on the windy, cool day we were there. The sounds of the place increased the sense of history in the ruins.

Air pollution during pregnancy may affect growth of newborn babies – There are so many aspects of the human impact on our environment that overwhelm what our bodies can handle…we should probably assume that there will be health impacts – particularly noticeable in the very young and the very old.

Burrowing Owls Face an Uncertain Future – They need holes from small colonial mammals….areas that are not plowed.

U.S. Power Sector Sees Biggest One-Year Drop in Emissions in More Than Two Decades – Picking up the pace as more renewables come online.

‘Inflammation clock’ can reveal body’s biological age – Maybe this turns out to be a good diagnostic to prompt interventions to extend healthy lifespan (via treatments on specific types of inflammation).

America’s First National Wildlife Refuge – Pelican Island National Wildlife Refuge….I’m including it in our plans for the next time we go to Florida; it’s about 1.5 hours to the south of Merritt Island National Wildlife Refuge which is always one of the places we visit in Florida.

Highly functional membrane developed for producing freshwater from seawater: A desalination membrane laminated with nanosheets featuring 2D nanochannels -- ScienceDaily – Still in the research stage. Maybe this is one of the technologies that will enable low-energy desalination - something we will need to avoid water shortages in many areas of the world.

A mild way to upcycle plastics used in bottles into fuel and other high-value products -- ScienceDaily and How Paving with Plastic Could Make a Dent in the Global Waste Problem - Yale E360 – Two articles about uses for the plastic waste that is overwhelming the planet right now. There still needs to be significant testing on plastic for paving: will it withstanding heavy traffic…will it shed microplastic particles, etc.

Pompeii's Museum Reopens With Dazzling Display of Archaeological Treasures | Smart News | Smithsonian Magazine – I enjoyed the article…and the website for the new museum.

A large number of gray whales are starving and dying in the eastern North Pacific -- ScienceDaily – Ongoing research but one explanation being explored in a decline in prey (i.e. amphipods) availability in their Arctic feeding grounds – maybe caused by warming there due to climate change.

For the Birds: Why Designing for Birds is Good for Everyone - News | Planetizen – Fast Company interviewed Tim Beatley about his book; he was one of the speakers at the Birds on the Niagara conference.

Wombats Poop Cubes, and Scientists Finally Got to the Bottom of It | Smart News | Smithsonian Magazine – Over 40,000 contractions as the feces moves down the intestine to shape a very dry cube. Evidently the cube shape is an indicator of wombat health!

Water Warning: The Looming Threat of the World’s Aging Dams - Yale E360 – Lots of people live downstream from big dams. Yikes! Decommission of dams is not easy…arguably it could be harder than the building of the dam originally.

Thousands of Wild Bee Species Haven't Been Seen Since 1990 | Smart News | Smithsonian Magazine – Most of the data came from Europe and North America….with some from the rest of the world. All of it sums up to a grim picture when it comes to bees.

Yellowstone's Hotspot Has Been Simmering For About 17 Million Years – An example of how continued data collection and study…can shift our understanding of geologic history even in areas like Yellowstone that have been studied for a long time.

Ten Little Celebrations – January 2021

And 2021 is off to a roaring start. Even with the jarring events of Jan. 6 and the pandemic still raging, there were plenty of reasons to celebrate in January 2021.

Bluebirds at our bird feeder –I celebrate when a bluebird group comes to our deck since it doesn’t happen very often. They seem to show up most frequently when there is snow and ice!

Piliated woodpecker in our forest – They don’t come to our deck…but are in our forest. I see them a few times each the winter when the leaves aren’t in the way. Their red heads are like flames. I think I saw a bald eagle a few times too this January. Even the fleeting sight of these birds is a celebration.

Amanda Gordan and the transition to a new President – A young poet and a shift toward hope for our troubled country toward a ‘forming a more perfect union’

Tennessee Crane Festival (virtual) – Lots of good webinars….dreaming about going to the place in January 2022. Celebrating learning about the place this year…and anticipating a visit.

Space Coast Birding and Wildlife Festival (virtual) – We went in 2019…hope to go to Florida again in January 2022. Celebrating the virtual version this year.

Success making a cheese omelet – I tend to make scrambled eggs but have omelet pans to cook them.  This month I opted to try making an omelet – perfect on the first try…celebrated the accomplishment (and the meal)!

Steak lunch – Our January days have been pretty cold, but my husband grilled on one of the warmer sunny days. A special lunch.

Carrot – coconut – chicken salad – I’ve discovered that if I layer a spoonful of orange marmalade, carrots, canned chicken, and coconut in a bowl….microwave it for a minute…stir…it makes a warm version of a favorite salad to enjoy in winter. Celebrating warm salads!

Howard County Sustainability Legislative Breakfast – Getting an update of what is happening locally re sustainability. I celebrated that good things are being worked at both the county and state level!

Tree trunk macros – It was a short project that I enjoyed a lot. The color and texture of winter tree trunks in our yard were celebration worthy!

Filling a Day of Social Distancing - 5/1/2020 - Gleanings

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Downloading Woody Plants of the Northern Forest by Jerry Jenkins.  The Northern Forest Atlas organization has 3 digital atlas guides: woody plants, mosses and sedges. They are available as free downloads (PDFs). The images are wonderful…the downside is that the guides are HUGE because of the high quality images. The woody plant guide is 630 MB. Put the download in a place you will remember to retain it as a reference (and avoid downloading it again).

Browsing the books illustrated by Frederick Richardson on Internet Archive. He illustrated books in the early 1900s. The samples below are from Edith Ogden Harrison’s The Enchanted House and Other Fairy Stories.

Walking laps. It’s been very wet here, so I’ve been indoors more. I’ve plotted various circuit paths through my house to get some exercise! I do laps for 5 or so minutes every hour…or that is the general goal.

Receiving a new office chair. My constant bouncing on the Swopper stool at my computer had recently started to bother my back rather than sustaining my back muscles….so I opted to move to a more traditional office chair. We had one that was over 30 years old that I thought might work but the height adjustment no longer functioned. My husband found a new chair from Staples…ordered it…and it came to our front porch within a day or so. It’s now assembled and will be the chair at my computer. The Swopper will still get used daily….but not as heavily as it has for the past 10 years!

My 2019 in Review - Travel

The Space Coast of Florida….Providence, Rhode Island…Carrollton, Texas…Cape May, New Jersey…Springfield, Missouri… Smith Island, Maryland…Scottsburg, Virginia --- these were the places we traveled in 2019.

The Space Coast of Florida was for a birding festival held in January. I had quite a few blog posts about it. That road trip got the year off to a fast start for birding.

In late March/early April, I traveled to Providence, Rhode Island on the train to take the CZT class (Certified Zentangle Training). I posted about the experience of the trip and the training here.

The only plane trip of the year was in April – to Carrollton for a niece’s wedding. And it was perfect timing for the pocket prairie (posted about here).

In May, the Cape May Birding Festival…another road trip and lots of birding…blog posts.

There were multiple trips to Springfield, Missouri during the summer to help get my daughter and son-in-law moved from Pennsylvania to Missouri. It’s a 2-day road trip in each direction…often with very full carloads of fragile stuff.  And then I was back for Thanksgiving too! I did a little exploring – the botanical garden, the art museum, and the conservation nature center. The posts are here.

The first attempt at a boat trip to Smith Island in the Chesapeake Bay was cancelled due to wind in April. The re-scheduled time was in October…and we enjoyed the trip. I posted about what we saw. The pelicans were the high point for me.

2019 10 h IMG_0990.jpg

Later in October, we were camping at Staunton River State Park near Scottsburg, Virginia for a star party. We’ve been going every year that the weather permits for the past several years. It’s always cold at night but we survive - enjoy ambience of a field of telescopes, tents, campers and cars. This year we took a short hike on one of the mornings.

Looking back – our travel was full of variety (places, activities, and seasons)…a good mix. I’m already primed for more adventures away from home in 2020!

Gleanings of the Week Ending November 9, 2019

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Infographic: How Air Pollution Could Affect the Brain | The Scientist Magazine® - A quick and disturbing summary. The evidence of harm: particles like those produced by vehicle engines found in frontal cortex (postmortem), reduced volumes of white matter, slowed development of children, inflammation related damage to brain cells, and higher accumulation of Alzheimer-associated proteins.

Happier Babies Have an Edge - Scientific American Blog Network – The more children experience happy emotions, the more time they spend building skills and relationships that help them in the future.

900 Pythons Removed from South Florida – That’s a lot of snakes. Kudos to the Python Action Team. There are other organizations (government and non-profits) working on this too. I wish the article would have included information about what they do with the snakes after they are captured. Presumable they are killed.

Study: 95 percent of baby food contains traces of toxic metals - UPI.com – Not good. The full report referred to in the article is available here. I wonder if pediatricians are changing their recommendation when it comes to some foods (like rice cereal for babies).

Newly discovered virus infects bald eagles across America -- ScienceDaily – Over 1/3 of America’s Bald Eagles are infected…and it might be causing a fatal disease – Wisconsin River Eagle Syndrome.

BBC - Future - What life might be like in alien oceans – Lots of possibilities. It will be interesting to get some probes (submersibles, etc.) out to the moons of other planets in our solar system that have alien oceans…maybe life.

From quills to typewriters: how the industrial revolution changed our writing culture | Europeana Blog – A little history lesson.

National Science Board highlights Skilled Technical Workforce shortage in new report - The Bridge: Connecting Science and Policy - AGU Blogosphere – “Without immediate action, the US risks falling behind other nations that are making significant investments in their Science and Engineering workforce and the Science and Technology enterprise.”  The whole report can be found here.

The Platypus Is Weirder Than You Ever Imagined – Cool Green Science – They don’t have a stomach, their venom can help treat diabetes, their milk can help fight antibiotic resistance….the list goes on.

Photography in The National Parks: Your Armchair Photography Guide To Olympic National Park, Part 2 – The Forests – National Parks….always a great destination for nature photography.

Gleanings of the Week Ending October 12, 2019

The items below were ‘the cream’ of the articles and websites I found this past week. Click on the light green text to look at the article.

Climate change may cut soil's ability to absorb water -- ScienceDaily – Climate change impacts everything. The models only model pieces of the puzzle. This study was looking specifically at water and soil – not currently included in models..

The Iguana Invasion – Cool Green Science – They’re a common sight in Florida….and the state is now advising people to kill them. No talk of eating them like they do in their native range further south and the Caribbean where they are farmed.

Sigiriya, the 'Lion Fortress' of Sri Lanka – A Heritage Site that survived by being hidden by forests…and being remote enough to not be marred by modern weapons of war.

Impostor syndrome is more common than you think -- ScienceDaily – Seeking social support outside academic (or workplace) specialization seems to be the best coping strategy.

Pregnant Moms' Air Pollution Exposure May Affect Babies' Health | The Scientist Magazine® - Research is ongoing. The first correlation was between air pollution and low birthweight/preterm birth. Current research is on other health consequences in the early life of the baby and beyond…looking beyond correlation to the underlying mechanism.

Top 25 Wild Bird Photographs of the Week: October – The headline picture is of a Green Heron!

BBC - Future - The simple words that save lives – Communication in an emergency…if it goes wrong…tragedy.

Despite growing burden of diet-related disease, medical education does not equip students to provide high quality nutritional care to patients -- ScienceDaily - Researchers call for improved nutrition education to be integrated into the medical curriculum. This makes sense to me…but why hasn’t it been done long before now?

Iceland's Seabird Colonies Are Vanishing, With "Massive" Chick Deaths – Kittiwakes, puffins, murres, fulmars – Chicks die…nests with eggs abandoned. Total breeding failure for many of the birds. For the Puffins it has been happening since 2005. Lots of changes caused by climate change funneling pollution from the North America and Europe to the North Atlantic: mercury ubiquitous and rising fast in some areas, brominated flame retardant, pesticides, PCBs, chemical laced microplastics. A caption under one of the pictures: “In Iceland, levels of PCBs and other contaminants are so high in murre eggs that people shouldn’t eat them.”

Rainy Morning at Merritt Island National Wildlife Refuge

The last morning of the Space Coast Birding and Wildlife Festival was rainy. We’d signed up for a field trip about birding by ear and habitat at Merritt Island National Wildlife Refuge. It was one of the few field trips that was not cancelled entirely but it was changed considerably by the weather. We talked through the topic of using other than markings for bird identification – songs, habitat, silhouettes, behavior…and then did the best we could to observe some birds. We didn’t do any hiking…just observed what we could from the visitor center and from within the car along the wildlife loop. Still – it wasn’t a bad morning for seeing birds. The visitor center has feeders that attract Painted Buntings this time of year. What a treat to see these brightly colored small birds!

Then it was out to the wildlife loop to look at water birds. The first one we saw was a smallish white bird at the edge of the water. In was in the right habitat for a heron or egret…about the size of a cattle egret but in the wrong habitat since they are usually in fields. It was a juvenile Little Blue Heron with green legs and a washed out looking face….definitely not a Snowy Egret.

There was a group of Northern Shovelers feeding – living up to the ‘shoveler’ name.

Glossy Ibis were feeding in the shallows and mud.

There were some Roseate Spoonbills feeding almost out of range of my camera. Watch the one in the center in this sequence.

There were was a mixed group of birds: Roseate SpoonBills, American Avocets, and a Great Egret. That area near that shore must have been rich pickings.

IMG_3710.jpg

A little further along the shower there was a group of American White Pelicans in the water. The group might have been working together to herd fish into the shallows – easy feeding.

Last but not least - a Tricolored Heron made an appearance. It too was looking for breakfast in the shallows.

IMG_3728.jpg

Overall – it was not a bad ending for the festival. It would have been better had it not be raining…and even better if the sun had come out. We picked up some snacks intended for some trips that were cancelled and headed back to the hotel to pack for the trek home the next day. Both my husband and I enjoyed the festival and I’m sure we’ll do it again – leaving more time between field trips (and before/after the festival) to do some photography at our own pace. It’s a rich area for birding and more comfortable in the winter than it is in the summer.

Another Florida Beach

After lunch at Dixie Crossroads, we headed over to a beach close to Titusville: Cherie Down Park in Cape Canaveral. It was a breezy cloudy day….a little cold. There were people fishing from the beach. At first it didn’t seem like there were very many birds. In some ways that made it easier to photograph the ones that were there.

The Sanderling at the water’s edge was the first bird I noticed.

The Ruddy Turnstone kept moving about. I’m not sure whether I photographed the same bird twice or it was two birds.

A Ring-billed Gull surveyed the beach from a pile of sand in the beach replenishment project area.

2019 01 IMG_3938.jpg

Further away a Lesser Black-Backed Gull and Herring Gull were doing the same.

2019 01 IMG_4116.jpg

A Pigeon posed with fluffed feathers…protection against the cold wind.

Lots of Brown Pelicans flew by.

2019 01 IMG_4050.jpg

I managed to catch a sequence of a group as it went by. The ones with white heads are the mature birds…the brown heads are juveniles.

A Willet walked along the water’s edge.

Just before we left a group of Black Skimmer’s flew by…a good high point for the last of the field trip.

2019 01 IMG_4132.jpg

Birding Near Titusville

After the long field trip to Central Florida, the next day we had a shorter one to hot spots around Titusville. It felt a lot easier getting to a 6:30 AM bus than the 5 AM bus the previous day. The first stop was Hatbill Park…just as the sun was coming up.

2019 01 IMG_3552.jpg

The Grackles were the first birds we noticed…because they were noisily welcoming the day.

2019 01 IMG_3549.jpg

As the light got better there were other birds to notice: a Little Blue Heron fishing in the shallows.

A Red-shouldered Hawk almost too far away to photograph but showing its very distinctive tail as it flew away.

There was an Eastern Phoebe and

2019 01 IMG_3685.jpg

Savannah Sparrow to represent smaller birds.

Some Brown Pelicans flew over the lake.

2019 01 IMG_3702.jpg

We headed off to or next stop – a walk back into the woods. There were very large Live Oaks with Spanish moss, resurrection fern, and ghost orchids and

Quite a few American Robins. Some robins stick around in Maryland but some push southward and accumulate in Florida.

2019 01 IMG_3749.jpg

There was a Red-Bellied Woodpecker that showed himself at just about every angle. They do have a little red on their bellies!

Florida has red maples just as we do in Maryland although the ones in Florida had formed their samaras months in advance of our trees.

2019 01 IMG_3776.jpg

Ball Moss – a relative of Spanish moss (both Bromeliads rather than mosses) – was growing in some of the trees. It looks tidy rather than raggedy like the Spanish Moss.

2019 01 IMG_3778.jpg

The Sabal Palmettos had ferns growing in their boots (the stubs of branches along the trunk). One of the other field trip participants identified it as a gold foot fern.

An Eastern Phoebe sat around long enough to be photographed here too.

2019 01 IMG_3805.jpg

One stop was a neighborhood pond that has a population of resident Black-Bellied Whistling Ducks. They were noisy. Hopefully they quiet down at dusk.

2019 01 IMG_3813.jpg
2019 01 IMG_3818.jpg

There were White Ibis in the pond as well. They seemed even more acclimated to people.

The next stop was a neighborhood park where there was a resident pair of Sandhill Cranes.

20190126_123310.jpg

Then we headed off to Dixie Crossroads (restaurant) for lunch. I took a picture of the mural as I came out of the restaurant – it featured a lot of the birds we had been seeing.

The post tomorrow will be about what we saw after lunch.
