Shoenberg Arid House at Missouri Botanical Garden

After enjoying the orchid show, we headed to the Shoenburg Arid House at Missouri Botanical Garden. It was a short walk, but we realized that the breeze made if feel even colder than the temperature. It felt good to get into a warm building again. The air was surprisingly moist – maybe because the plants had been recently sprinkled.

There were cactus and aloes and yuccas…almost every plant had sharp points some place! A few of the cactus were blooming. It is not a large building so the plantings are relatively dense – closer together than they would be in their natural environment.

It was my first time to visit this conservatory since it opened in 2024 after a renovation…transitioning from temperate to arid plants. I liked that it is multi-level (a long ramp or stairs) and the central court. It is a get place to showcase arid plants.

Orchid Show at Missouri Botanical Garden

We made a road trip to St. Louis last weekend for the Orchid Show at the Missouri Botanical Garden. It is just over a 3-hour drive from our house…with some interesting road cuts along the way (more on that in another post). The temperature was in the 30s so our plan was to see the orchids then browsed the other conservatories rather than spending time wandering through the outdoor garden area. Our membership in the Springfield Botanical Garden gained us free entrance. The Orchid show was in the Emerson Conservatory, so we didn’t even need to go outside for it.

There were orchids everywhere. Some of my favorites: orange ones in sunlight (my mother’s favorite color was orange…a good memory prompt),

Shapes that had me wondering about what kind of pollinator the flower needed,

Small and delicate,

Ones that seem to have alien faces…and elaborate ‘fashion,’

Clusters of spirals.

I used my phone (iPhone 15 Pro Max) on a lanyard and an external clicker - was pleased with how well it did. There were other people using their phones too. One lady was making a video which was going to be dizzying to look at because she was moving the phone so quickly. I talked to a lady that was doing excellent macro compositions with her phone….no other amenities. Another person that I talked to had lived in DC for 20 years but had grown up in St. Louis and had lived closed to the Missouri Botanical Garden for a few years when she visited almost every day. She had moved away but had made the effort to return with her mother for the orchid show.

Almost all the slipper orchids were low…the better to see into the slipper. I found myself taking mostly macro images although I also took some small landscapes and some plants that were providing greenery around the orchids.  Enjoy the slide carousel of orchids!

Tomorrow’s post will be focused on the other conservatories at Missouri Botanical Garden.

Project FeederWatch – February 2025

Our fourth month of weekly Project FeederWatch counting continued with our regulars: white-crowned sparrows, white throated sparrows, house finches, gold finches, cardinals, dark eyed juncos and mourning doves….and unfortunately starlings. The chickadees, Carolina wren, titmouse, and downy woodpecker are occasional visitors.

We had two surprises recently –

  • A fox sparrow showed up on a very cold, snowy day and ate for almost our whole observing time…and stayed in the area for the duration of the very cold weather.

  • A red shouldered hawk made an appearance in our yard. I think it lives in our neighborhood, but I hadn’t seen it come as close to our feeders before. All the birds around our feeders disappeared well before we saw the hawk swooping in from the direction of the pond. I’m not sure which one raised the alarm but they scattered very quickly.

When snow is on the ground, it seems like  the birds are more frenzied at the feeders and any seed that has spilled onto the ground below. They need calories to keep themselves warm! The Caroline wren never seems to be around when it is very cold and I wonder where it stays….hope it survived.

Gleanings of the Week Ending March 1, 2025

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.

Scientists Investigate Smell of Egyptian Mummies – A systematic study of the smells of 9 Ancient Egyptian mummified bodies. Odors are from pine, cedar, juniper, frankincense and myrrh.

'Healthy' vitamin B12 levels not enough to ward off neuro decline – The conclusion: “we need to invest in more research about the underlying biology of B12 insufficiency, since it may be a preventable cause of cognitive decline.”

Rethinking Fire-Resistant Landscaping: Which Trees Should We Plant? – After the recent wildfires across Southern California - Experts recommend replacing highly flammable trees with fire-resistant alternatives such as oak, sycamore, toyon, lemonade berry, and lilac. While the idea of removing iconic palm trees may be met with resistance, fire safety advocates argue that proactive changes in landscaping are necessary to adapt to the increasing wildfire risks in California.

Floods Swamp Tennessee – Satellite image from February 17 of the flooding after the February 15-16 storm. The area of western Kentucky to the north had more severe flooding….but clouds prevented a similar image on the 17th.

Learn COVID pandemic lessons — before it’s too late - “The science will deliver if we have a new emerging infectious disease,” says Joanne Liu, a pediatric emergency-medicine specialist at McGill University in Montreal, Canada, and a former international president of the medical-aid organization Médecins Sans Frontières (also known as Doctors Without Borders). “I think it will be the people who aren’t going to deliver…..None of us thought about the case scenario in which we would have leaders and a large part of the population that do not believe in science.” Yet that scenario is here. It means that researchers in public health and infectious diseases must work closely with social scientists who have been studying how another disease — misinformation — spreads and how best to counter it.

In many countries, people breathe the cleanest air in centuries. What can the rest of the world learn from this? – Lots of graphs….focused on sulfur dioxide and nitrogen oxide emissions….and the relationship to coal and catalytic converters.

The Science of Snakehead Slime - One of this fish’s most reported habits is its ability to move about on land. The answer, according to new research, may lie at least in part with another of the snakehead’s infamous features: its slime.

Wide-Eyed Fly Wins the 2024 Royal Entomological Society Photography Competition – Macro photography of insects…great work my amateur photographers. My favorite was the ladybird larva feeding on a colony of aphids.

How much protein do you really need to get strong? – A concerning take away: In 2018, a nonprofit group called the Clean Label Project, based in Broomfield, Colorado, released a report about toxins in popular brands of protein powders in the US. Researchers screened 134 products for 130 types of toxins and found that many protein powders contained heavy metals (lead, arsenic, cadmium and mercury), bisphenol-A (or BPA, which is used to manufacture plastic), pesticides, or other contaminants with links to cancer and other health conditions. Interestingly, one certified "organic" product had twice the contaminants of non-certified ones. Plant-based protein powders were the most contaminated, while egg and whey-based powders were found to be the cleanest.

Dust from Car Brakes More Harmful than Exhaust – Brake dust evidently causes greater injury to lung cells than diesel exhaust. Brake pads on the market now include copper which can aggravate asthma when inhaled. Note: the shift to electric vehicles could curb pollution from brake pads. Most electric cars use regenerative braking that limits the need for conventional brake pads.

Very Cold Weather

Last week we had snow and some very cold days with temperatures in the single digits (on both sides of 0 degrees Fahrenheit. Fortunately we had been paying attention to the forecast and could simple stay indoors for 3 days!

I took some pictures through the window on the second morning. There was still snow caught in the holly trees around our bird feeders…and there was enough breeze to move our wind chimes. Later in the day most of the snow had been knocked out of the trees.

In the afternoon, I opened the door to our deck for a few seconds to get a picture of the chairs with snow drifts. The wind was still redistributing the snow; when the sun was out, it looked like there was glitter in the air.

I bundled up and went out to assess our driveway…no melting even though the sun had been out for most of the morning. The temperatures were too low.

I shoveled about a third of our driveway before a neighbor came home and walked over to ask if I wanted him to use his snow blower on the rest of it. Yes!!! He said he had gone to Kansas City to buy it a last month and I am now thinking we might need to do something like that too!

Ten Little Celebrations – February 2025

February was busier than usual this year – a combination of a class, a new role for me in the Missouri Master Naturalist chapter, and some significant volunteer hours. It all made for plenty of little celebrations.

Owl Pellets. Having 28 children busily dissecting owl pellets – finding and identifying tiny bones. I celebrated that we picked something they all seemed to enjoy doing all the way to the end of our time (and a little beyond).

A new protein drink. Another whey-based protein drink that already has lactase added…worth celebrating for the convenience (and also because it is not as thick or expensive as the one I had been buying).

Niece going to have another baby. My sisters and I celebrated that there will be another baby in the family next fall. My sister that is the grandmother shared the news with us almost as soon as she found out.

Snowy Feeder Watch day. I celebrated the extra birds that came to our feeders when snow was on the ground.

Seeing lots of Northern Harriers. I celebrated seeing Northern Harriers on our field trip to Lockwood MO. We’d seen them before in New Mexico but not as many…and it’s thrilling to see them closer to where we live.

Lunch with my daughter. My daughter and I have been meeting for lunch a Student Union dining room after my geology class. It feels celebratory every time we meet (and we generally have dessert too).

Finding witch hazel. I celebrated when I found a witch hazel in bloom at the Springfield Botanical Garden…even though I was hoping to see more of them.

Grandniece and grandnephew. I celebrated seeing my sister’s grandchildren when I went to Dallas to visit my father. One is just learning to crawl, and the other is reasonably adept at recognizing/saying colors.

Snow day. A day of staying indoors due to weather – always a time to celebrate. The day seems like a serendipity block of time that I had not anticipated.

Soup. Soup is my favorite meal on cold days. I celebrated finding a quick and tasty one made from ingredients in my freezer: turkey meatballs, corn, broccoli, and edamame….a little seasoning and sometimes left over spaghetti sauce…delicious.  

Zooming – February 2025

There seems to be more going on this winter than usual. Most of the pictures I selected to represent February were taken within a 100-mile radius of home in Nixa MO…except for a few at the Josey Ranch ponds in Carrollton TX. There were some warm days…and some snow. Some of the bulbs are coming up --- growing slowing in the still frigid temperatures that keep coming. Enjoy the February slideshow!

Learning about Missouri Geology – February 2025

The geology class/lecture I am taking at Missouri State University is providing good background in general geology…but I am most interested in the geology of Missouri…trying to be more aware of the geologic features around me.

My copy of Roadside Geology to Missouri has been a good reference. On the drive from Nixa to Branson, MO, my husband’s navigation system took a scenic route (to avoid a construction area); the two-lane road was predominately downhill and followed Woods Fork over to US 65.

The road cuts are spectacular along US 65 with one of the tallest marking the margin of the Springfield Plateau…and then the Salem Plateau as we continued south. There are layers of limestone, dolomite, and shale. There were frozen ‘waterfalls’ from some of the cuts. The day was sunny, so it was easy to get pictures of the cuts as we moved past.

We stopped at the Branson Scenic Overlook downstream from the dam that created Table Rock Lake. The overlook area was the first proposed location for Table Rock Dam. There were evidently too many cracks and faults in the rocks to build it at this location. The dam was built in the 1950s and spans the White River creating the deepest lake in Missouri.

The view for the overlook shows Branson and the lake in the distance but I was more interested in the river immediately below…the bare trees and remnants of snow…ripples in the cold water.

Our field trip to the prairies near Lockwood MO (from Springfield) took us from the Springfield Plateau to the Osage Plains. It was a very cloudy day, so I took few pictures - I did notice the flattening out as we drove around farmland with parcels being maintained as prairie. There were low rolling hills. There was a significant windfarm….indicating that the wind there is reliable enough to make it worthwhile.

The final geology adventure in February was the monthly Missouri Master Naturalist meeting. The topic for the month was Missouri Geology!

Josey Ranch – February 2025

The weather was cold and mostly cloudy…but I headed to Josey Ranch for a nature fix – and to gain more experience with my new camera (Nikon Coolpix P950). The last time I visited was back in September, but I expected to see a lot of birds that are in Texas during for the winter. The pond between the library and the senior living complex was almost empty. I photographed a feather and a dandelion almost ready to bloom before I headed over to the other pond.

There were a lot of birds: American Wigeon, Northern Shoveler, Canada Geese, Greater Scaup, American Coot, and Ring-billed Gull (many immature).

There were pigeons and crows on the tall lights over the ball fields.

Surprisingly there were cormorants on the poles as well!

I headed back toward the larger pond and my car…noticing some mistletoe in a tree along the way.

There were a pair of Great Egrets that interacted and then flew away from each other. The breeding plumage is beginning to be obvious.

A group of mallards and domestic duck hybrids were on a small pond. One hybrid was mostly black but had a green head!

Back at the larger pond I saw sleeping Ruddy Ducks.

I got a better view of a cormorant on the pond. It seems to have some characteristics of a Double-Crested (bare skin in front of the eye) and the white line of the Neotropic. I read that there are instances of hybrids in the areas where the two species interact….and north Texas might be one of those places!

The cold and wind had me regretting wearing leggings rather than jeans….it was time to head back to the car.

More Snow

We had more snow last week…not as much as our previous snow day. The temperature hovered around freezing so it was slushy from start to finish. I took some pictures around the peak accumulation. There was no breeze so the pines and cedars and seed pods and patio furniture held the wet snow.

My favorite was my young eastern red cedar; I hope it survives transplanting in the spring.

The birds were very active at our feeders – as they were during the last snow. Unfortunately, a flock of about 15 starlings swarmed in and took turns at the feeders chasing the smaller birds away.

The street in front of our house is barely covered with snow and it appears to be melting. Hopefully it will simply melt and it won’t be a problem to get out and about tomorrow.

Owl Pellets!

The topic of the session at the two libraries in a nearby county was owls. Since it was the third event for our 3-person team of Missouri Master Naturalists, we were beginning to get better at it…although it was still hectic. This time we had a mounted owl and wing,

handouts,

a display on the wall showing the wingspan of various owls (click on the right image to see the list of owls by wing span), and

the equipment (tweezers, picks, plates, gloves, identification sheets, containers for bones) to dissect owl pellets).

And then the first group of children arrived at the library. There were 28 students and 12 parents. We had a short lecture that included listening to the sounds of the 8 owls of Missouri (4 year-round and 4 more in winter). One student had a Great Horned Owl near where they live. Then the fun began as we handed out equipment and foil wrapped pellets. The students thoroughly enjoyed teasing apart the pellets and finding bones – mostly rodents.

We packed up everything and left the room as we found it…and went to the second library…to set up a second time. It was disappointing that only 3 students came for that session. But we made the best of it and dissected pellets ourselves sitting across from the students.

These are the bones from my pellet!

We have one more session in our series for the library. They’ve been a learning experience for me as a volunteer. I am realizing that the volunteering I did in Maryland was skewed toward the actual event (rather than prep) because others had done the preparation and the audience from multiple schools rotated through experiencing the same program. It was easy to get very polished at presenting the program and the number of students reached was quite large. I’d like to find volunteer opportunities like that here in Missouri, but I am not sure they exist.

Our Missouri Yard – February 2025

It was a warm day in February when I took a walk around my backyard. I wasn’t in the mood to do any work…but I did mentally begin to make a list. The yew branches I scattered over some bare soil in my wildflower garden when I trimmed the bushes last fall are still green! I thought they would be rotten by now. The other green is Japanese Honeysuckle which I need to get to pull and dig so it won’t take over the area. There is a small eastern red cedar that has come up at the edge of the bed and I will dig it up to plant elsewhere in the yard to increase the privacy of our back patio and deck. Perhaps my aromatic sumac is large enough to make seeds this year.

There are iris coming up in the mulch from last year’s irises and violets. They look fresh and green. In years past they have weathered the late frosts of winter and gone on to bloom. Hopefully that will happen this year too.

There was a feather among the leaves near the small spicebush I planted last fall. There was only one feather so maybe it wasn’t the remnants of a predator’s meal. I have high hopes that the spicebush with thrive and grow a lot over the next summer. That side yard has pawpaw and persimmon and buckeye seeds planted…will be quite the patch of understory trees if they all come up. Right now the daffodils are beginning to come up…a first sign of spring.

In the other side yard, the Ozark witch-hazel is bare. Hopefully it will grow a lot this next summer…but it still might not bloom for a few more years; the normal bloom time is January/February. The irises I planted from my parents’ garden are up along the fence. I’m not sure if they will bloom this year or not.

My plan to gradually reduce the amount that will need to be mowed in the summer seems to be working!

Springfield Botanical Garden – February 2025

It was not a great day to go to the Springfield Botanical Gardens – cloudy and chilly….but I wanted to try out my new Nikon Coolpix P950 camera. My husband did the driving to the garden and he brought along his camera too even though he didn’t use it.

It was not a day for landscapes but there was enough light to get some zoomed pictures of winter plants – dried flowers from last summers’ hydrangeas, some evergreens with enough color variation and texture to be interesting, berries that the birds are reluctant to eat, and dried grasses.

I saw one witch hazel and it was booming. This is its normal time to bloom so not exactly a sign of coming spring.

There were some bulbs peeping from the mulch….which seems more aligned with the notion that spring is coming.

There were some succulents and prickly pear cactus that seemed in better shape than I expected after the very low temperatures a few weeks ago.

It was a good first field trip with the camera…a learning experience without much pain. I somehow managed to not charge the battery completely so it was depleted very quickly…and I initially couldn’t see through the viewfinder with my glasses on….but my husband helped fix that problem with a slight adjustment on a knob that had no equivalent in my previous camera.

I am ready to try some bird photography later this week!

New Camera

I have been using Canon cameras for a long time but they aren’t updating (creating new models) of their bridge camera (Canon Powershot SX70 HS) so I am transitioning to the Nikon bridge camera: Nikon Coolpix P950. My husband helped me along by ordering everything just as he did last April which I transitioned from Samsung phone and Dell computer to Apple products: iPhone and MacBook Air. This past year has been a tech pivot for me!

The box with the new camera came when I was busy with other things…but I opened it to take out the two small manuals about the camera to look at while I went off to get my car serviced. I realized that I needed to browse the full reference manual to become as proficient with the new camera as I am with the old – to avoid frustration when I am on field trips.

I unloaded the rest of the box: the camera, a camera strap, a lens hood, a battery, and a charger (to charge the battery when it is in the camera).

My husband had ordered some other things: a charger for batteries when they are outside the camera, 2 extra batteries, a better camera strap (Peak Design), and a strap for the lens cap (since I don’t always have a pocket for it). I attached both straps to the camera body.

The battery in the box with the camera was already charged and I had a new SD card---so it was easy to get to the point of turning on the camera. I set the time zone, date, and time then formatted the SD card. And took a few pictures. Two are yard art through my office window and the other is of a picture on the wall of my office.

Next step: browse the reference manual and plan a field trip!

Our Missouri Neighborhood – February 2025

We had a day in the upper 60s in February!!! It was a great day to walk around the neighborhood. The beds planted with native wildflowers at the edge of the pond are new – a next-step in the project to put more natives in the shallow water and along the edge of the pond. The water plants were done first and surrounded my wire mesh to protect them until they are established. This second phase was cardboard covered my mulch and planted with native wildflowers…mostly coneflowers based on the labels I could see.

The turtles were enjoying the sunshine and warmth. There was a group on the small island – primarily facing the bank. All except one slid into the water as I got closer.

There was one on the opposite bank – a little higher out of the water….looking out over the pond. Perhaps it was a different kind of turtle?

I saw a pair of mallards in an area with some downed branches. The female was alert as I neared…but male stayed asleep. There have been ducklings on the pond for the last two years, but the turtles have gotten them. I wondered if the pair I saw was the same as in years past and if they will try again this year. Based on the number of turtles I saw (and their size), I think our pond is probably not be a good place for ducklings.

Field Trip to Prairies around Lockwood MO

My husband got the announcement about field trips from the local Audubon chapter and suggested the day trip to the Lockwood area to (hopefully) see Northern Harriers and Short-eared Owls. The group met in a parking lot before setting out as a caravan of cars; walkie-talkies were handed out to enable communication along the way.

We were surprised that most of the field trip was spent in the car – driving around on country roads with small farms (lots of cattle) with occasional prairies managed by the Missouri Prairie Foundation or the Missouri Department of Conservation. We did see lots of Northern Harriers and Red-tailed Hawks and Kestrels and Shrikes and a flock of red-winged blackbirds (maybe with some other kinds of blackbirds mixed in) large enough to fly up into a murmuration. No short-eared owls though. We did see a Prairie Falcon!

I didn’t take any pictures as we drove around although in retrospect maybe I should have leaned out the window with my camera.

We stopped for lunch at Cooky’s Café in Golden City, MO for lunch – the leaders of the trip having called ahead to let them know the number of people and the approximate time we’d arrive. It worked out well. The food was good and there was a great selection of pies for dessert.

We stopped late in the afternoon at Niawathe Prairie Conservation Area and walked to the top of a low hill to look for owls. They had been spotted there recently. I took some pictures of the winter prairie from the top.

There were occasional holes (armadillo probably) big enough to be dangerous to anyone walking the prairie in the dark so we went back to the cars to try one more place as the sky became colorful.

We drove past another prairie where short-eared owls had been seen recently. No luck.

I contented myself with two sunset pictures as we headed back to Lockwood…and then home.

The area has a fair number of wind turbines. We noted them early in the field trip and as we drove around….and then we got to see the red lights that flash in unison at night!

This was our first field trip with the local Audubon chapter and we’ll be doing more. I need to think about how to do more photography. There were several people that were using a better bridge camera than my current Canon Powershot SX70 HS…and my husband opted to order one for me. Good birds and good tip on a new camera…a well spent Saturday.

Winter Seed Sowing

I assisted one of my fellow Missouri Master Naturalists with a program for her county’s libraries – planting seeds in plastic jugs for planting in gardens next spring. There were about 50 participants (plus parents) that participated across the two sessions. The set up included lots of plastic jugs (saved from distilled water purchased for humidifiers), soil, gloves, tarps to protect the carpet of the library meeting rooms, scissors, and seeds. I took pictures of the brief calm between set up and the chaos of everyone getting dirt and planting their seeds.  

The battery powered drill was used to make holes in the bottom of the jugs and marker holes to cut the top part almost off…leaving a 1-2 inch hinge. Most of the children were young enough that we recruited parents to make holes in the jugs.

Several of the older children mixed the soil with water in big buckets for everything else to use. We had native wildflower seeds but almost half the children chose to plant vegetables. An older lady chose to plant common milkweed in her jug…and she is going to plant the seedlings near some buckeyes in her yard in the spring.

Each hour-long session was a whirlwind of activity. We managed to contain the mess with the tarps on the floor, so cleanup was not bad. I was grateful that we had some extra help from some local Master Gardeners and the parents of the children jumped in to help too.

Gleanings of the Week Ending February 1, 2025

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.

Warmer, Greener Arctic Becoming a Source of Heat-Trapping Gas - Roughly half of the region is growing greener, but only 12% of those greener areas are actually taking up more carbon.

More Than 100 Died When the S.S. Valencia Wrecked in the ‘Graveyard of the Pacific’ - Not long before midnight on a night with poor visibility in 1906, the Valencia struck a rocky reef off the west coast of Vancouver Island. The captain ordered the ship run aground, but it caught on rocks less than 400 feet from shore….and sank over the next 40 hours. The rough seas made it difficult of lifeboats and many capsized. 136 people died, 37 survived. Weather, waves, swift currents and a shifting sandbar made the area particularly hazardous, even for experienced captains. Lessons learned from the wreck of the Valencia are its most lasting legacy.

Menopause research is globally underfunded. It’s time to change that - The overwhelming majority of studies in the field of ageing do not consider menopause…and yet half the population will experience it. The disruptive nature of menopause and its health impacts have been known perhaps for millennia and should have been a topic for health funders for a long time. It is never too late to start.

How To: Go Snow Day Birding (with Merlin) – A good idea for a snowy day (maybe not if the temp is in the teens or single digits though).

Fighting Forest Pests With AI: A Hemlock Success Story – Fighting the hemlock woolly adelgid…increasing the odds of saving some trees. It’s too late for the ones behind where I used to live in Maryland. They succumbed to the pest years ago.

Incredible Winners of the 2024 Ocean Art Underwater Photography Contest – I like the ones that are good documentation of a species…and art at the same time.

In the Northeast, 50% of adult ticks carry Lyme disease carrying bacteria – Not good for public health

Inca Tunnel System Identified Under Cuzco – More than a mile of tunnels that reflect the streets and walkways in the Inca capital.

Archaeologists in Pompeii Discover Private Spa Where Dozens of Guests Bathed in Luxury 2,000 Years Ago – Found in a lavish home…big enough to host 30 people. Three rooms: calidarium (hot water), tepidarium (rub oil on skin and immerse in warm water), and apodyteriaum (changing room with mosaic floor). The spa was connected to a banquet room decorated with elaborate frescoes depicting characters from the Trojan war.

New study identifies how blood vessel dysfunction can worsen chronic disease - Specialized cells surrounding small blood vessels, known as perivascular cells, contribute to blood vessel dysfunction in aging, chronic diseases such as cancer, diabetes and fibrosis.

Zooming – January 2025

January was a busy month but not one that included any big photography opportunities! My selections for zoomed images this month have some themes: sunrise/sunset, snow, birds, and lights. They are mostly from Missouri (although there are two that are left over from my trip to New Mexico in December that I didn’t post about until January). Enjoy the photographic mosaic.

Gleanings of the Week Ending January 25, 2025

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.

How Will Climate Change Affect the Spread of Invasive Species? - The silver lining of knowing humans are still one of the main drivers of invasive species spread, is that humans can also curb invasive species spread. We can plant native plants in our yards and gardens instead of ornamentals from other states and countries. We can clean our boots, shoes, fishing waders and boats when we travel from one area to another, and we can stop releasing unwanted pets into local parks, ponds or creeks.

Kangaroo species went extinct in the Pleistocene - Nearly two dozen kangaroo species vanished in the Pleistocene. If things get warm enough, dry enough, kangaroos today are going to have a tough time making it, regardless of whether they're mixed feeders.

Medieval Crowns and Scepters Discovered Hidden Inside the Walls of a Crypt Beneath a Lithuanian Cathedral – It had been hidden for 85 years—since it was stowed for safekeeping beneath the Vilnius Cathedral in southeastern Lithuania - put there at the outbreak of World War II in 1939.

Your work habits may be threatening your sleep - Sedentary workers experience a 37% increase in insomnia-like symptoms. Employees working nontraditional schedules experience a 66% greater risk of needing 'catch-up sleep.' It’s more about how jobs are structured and staffed than individual ‘habits.’

Bold Parakeet Biting a Lizard’s Tail Wins SINWP Bird Photographer of the Year Contest – Lots of great photos!

Renewables Supplied Two-Thirds of Germany’s Power Last Year - In Germany the solar buildout continues to surpass government targets, with solar now amounting to 14 percent of power generation. Wind remains the biggest source of clean electricity, accounting for 33 percent of generation, though new wind farms are being developed more slowly than planned. Along with new renewable power plants, Germany is seeing a growth in battery storage as homeowners install batteries alongside rooftop solar panels.

Why just two hours of exercise a week can be life-changing - One retrospective study of over 37,000 people found those who did their week's worth of physical activity over just one or two days had the same reduction in cardiovascular disease risk as those who did activity spread throughout the week.

Lead pollution likely caused widespread IQ declines in ancient Rome, new study finds - Scientists used Arctic ice core records to reconstruct historic atmospheric lead pollution in Ancient Rome and link exposure to cognitive declines. Ancient lead pollution stemmed largely from silver mining, whereby the lead-rich mineral galena was melted down to extract silver. For every ounce of silver obtained, this process produced thousands of ounces of lead -- much of which was released to the atmosphere. In the 20th century, lead pollution predominantly came from the emissions of vehicles burning leaded gasoline.

A Half Mile Underwater on Connecticut’s Eight Mile River - Designated a Wild and Scenic River. Black rock geology and tannin in the water take most of the light making visibility to a snorkeler limited.  Caddisfly larvae, mussels, Chinese snails (invasive, aquarium escapees), musk turtle, white sucker, common and spottail shiners, sea lamprey (a native here, unlike in the Great Lakes), redbreast sunfish.

Pirates, princes and hostages: inside the mysterious life of the unnamed medieval princess of Cyprus – An example of how medieval women found ways to overcome the limitations placed on them…but not one with a ‘happy’ ending.
