It’s a trap: managing cowbirds to save songbirds – The strategy of trapping cowbirds (a brood parasite) to help endangered songbirds along the Santa Clara River in Southern California has evolved to reduce harming other species and cost less.

Electric vehicle buyers want rebates, not tax credits – Of course….immediate rebates rather than waiting for months to get a tax credit are much more appealing.

Urban waterways: discovering the hidden beauty of a Jersey River – River restoration across the country…with the Cooper River story in more detail.

10 Weird Australian Marsupials You’ve Never Heard Of – So many unusual animals…Australia has more than just kangaroos and koalas!

Cancer probably killed world’s first known pregnant Egyptian mummy – 2,000 years ago a young woman died…and was mummified. The Warsaw Mummy Project has determined that she was pregnant – the fetus was ‘pickled’ in the highly acidic and low oxygen environment of the mummified womb – and the woman probably died of nasopharyngeal cancer.

More Electricity from Wind and Solar than Nuclear for 1st time in USA – Hurray! Wind and solar accounted for over 25% of the nation’s electricity in the first 4 months of 2022!

Loss of male sex chromosome leads to earlier death for men – What? Y chromosome loss happens in 40% (estimated) of 70-year-old men. The loss occurs primarily in cells with rapid turnover, such as blood cells. And it might lead to heart muscle scaring…and then heart failure.

New species of giant waterlily is the largest in the world – It has been growing in Kew Gardens in 177 years and in a herbarium in Bolivia for 34 years….always assumed to be the well-known species of giant waterlily named after Queen Victoria. The leaves can grow up to 10 feet wide…and support at least 176 pounds!

Toads surprise scientists by climbing trees in UK woodlands – Even when we think we know a species well…there are still surprises!

Get a Sneak Preview of the 2022 Bird Photographer of the Year Finalists – Capturing birds in action…rather than portraits.

Invasive species taking over some American forests - Amur honeysuckle (a shrub from Asia) is a big culprit. Callery Pear (the ‘wild’ version of the Bradford pear) is a close second.  I just cut down a Callery Pear that was growing in the front bed of my new house in Missouri…almost obliterating a crepe myrtle! Other foreign species that have become problematic: porcelain berry, tree of heaven, winged euonymus, European buckthorn, Oriental bittersweet, common privet and lesser periwinkle...Norway maple, Amur cork tree and white poplar along with herbaceous species such as lesser celandine, garlic mustard, Japanese knotweed and Japanese stilt grass.

A Surprisingly High Number of Wildfires Are Caused by Electrocuted Birds – Awful….good that there is a way to reduce the carnage…at less cost than the consequences of the fires.

Rural areas near coast will bear the brunt of US sea-level rise – Analysis focused on the Chesapeake Bay…marshes forming where forest and farmland is today.

Once-Common California Bumble Bees Have Gone Missing – The survey did not find the formerly abundant Western bumble bee. The last statewide survey was conducted 40 years go…and a lot has happened in that time: habitat loss, pesticides, and climate change. None of the species were doing well. Big problem – since bumble bees help pollinate $3 billion worth of crops in the US each year (including tomatoes, peppers, and cranberries).

Scientist war of links between soil pollution and heart disease – The author of the study commented: “Until we know more, it seems sensible to wear a face mask to limit exposure to windblown dust, filter water to remove contaminants, and buy food grown in healthy soil."

Living with the prospect of assisted dying – A post about a man diagnosed with ALS…difficulty with the bureaucracy of assisted dying laws even with a clear-cut terminal diagnosis.

Alaska Ablaze – 5,000 lightning strikes…dozens of wildfires.

How to turn your garden into a carbon sink – Turning more yards into gardens…with more diverse plantings….a few more trees. Sometimes going a little wild is a good thing!

Pollen and Heat: a looming challenge for global agriculture – heat is a pollen killer for canola, corn, peanuts, and rice. It is becoming more important than ever for crops to bloom before the temperature rises…and it is getting more challenging as multi-day stretches of excess heat are becoming more common early in the growing season.

The life of a solitary bee – There are as many as 4,000 bee species in the US….and most of them are solitary. 98% of the native bee species in the US are solitary.

What if all roads went underground? – Thought provoking…wish there were ways to make it a more practical solution since the aesthetics of a world that has more natural surfaces (rather than roads) is very appealing.

Endangered Whopping Crane Hatches at Smithsonian National Zoo Site – The egg was found on an abandoned wild nest in Wisconsin and given to a pair of whooping cranes in the zoo that had produced 2 infertile eggs. The live egg was put into their nest on 5/18 and the baby crane hatched on 5/26!

BLM, Forest Service, Five Tribes of The Bears Ears Commission Commit to Historic Co-Management Of Bears Ears National Monument – Wishing the best for this endeavor.

Antarctica’s ‘Doomsday Glacier’ melting at fastest rate in 5,500 years – Thwaites Glacier (nicknamed the Doomsday Glacier…Florida-sized) and Pine Island Glacier were studied. The ice shelf holding the Thwaites Glacier could collapse withing 3-5 years.

Finding mini frogs: these aren’t babies, they’re just little – And they hatch as frogs…no tadpole stage. They live in leaf litter…humid and moist but not near water.

New safe-sleep guidelines aim to reduce infant deaths – New guidelines have been coming out from time to time at least since my daughter was born over 30 years ago. When she was a baby, the recommendation was for babies to sleep on their tummy…very different from these current guidelines.

2021 Share the Experience Photo Contest (National Park Foundation) Winners – Special places…full of great experiences.

Los Angeles becomes the latest city to hire ‘chief heat officer’ – Miami and Phoenix as well as cities in other countries (Athens, Greece; Freetown, Sierra Leone; Monterrey, Mexico; Santiago, Chile) have similar positions.

One in 500 men carry extra sex chromosome, putting them at higher risk of several common diseases – A surprising result…most of the men were unaware they carried an extra X or Y chromosome. Those that are XXY had higher chances of reproductive problems. Both XXY and XYY individuals has higher risks of type 2 diabetes, deep venous thrombosis, pulmonary embolism, and chronic obstructive pulmonary disease.

8 cool wild cats you probably don’t know – So many wild cat variations!

Fjords emit as much methane as all the deep oceans globally – When storms churn up water in fjords….oxygenating the fjord floor…methane emissions spike. If the water mixed more frequently the methane emissions would drop because anoxic environments at the bottom of fjords would disappear.

Tree rings are evidence of megadrought – and our doom – Tree ring data indicates that the 22-year period from 2000 through 2021 was the driest and hottest in the last 1,2000 years for the North American Southwest. There was another 22-year drought from 1571-1592 that was nearly as dry but not as hot as the current drought. And the water distribution allocations were made based on a 22-year period between 1900 and 1921 that we now know was an anomalously wet period for area! Not good signs for the future.

A 3400-year-old city emerges from the Tigris River – Drought lowered the Mosul reservoir. There was a quick survey…discovery ceramic vessels with 100 cuneiform tablets…and the conservation measures to project the site as the water rose again. The site is now completely submerged.

Fifty years later, Kim Phuc Phan Thi is more than ‘Napalm Girl’ – One of the most iconic photos of the Vietnam war…still makes be as emotional now as the first time I saw it. She says – To confront violence head-on…’the first step is to look at it.’

Two articles about the flooding in Yellowstone: Repairing and reopening Yellowstone National Park won’t be easy and Extreme flooding devastates Yellowstone, forcing the closure of all park entrances – Very sad….also scary.

Wildlife bedtime: weird nesting habits of North American wildlife – Black bears, black-footed ferrets, jumping spiders, bald-faced hornets, and red-sided garter snakes.

How Vivian Maier, the Enigmatic Nanny Who Took 150,000 Photographs, Found Her Place in History – Street photographer…that only became known after a storage locker of her photographs/negatives was auctioned off when she couldn’t make the payments on it.

Zapping orange peel oil into new, pleasant aroma compounds – I’ve always liked the smell and taste of orange peel (I buy organic oranges and use the whole orange!) but evidently the compound that is in orange peel, limonene, can be the starting platform for other scents as well.

“Legacy Pollution” to be cleaned up in seven national parks – I am pleased that it is being cleaned up…chagrined that taxpayers are paying for it rather than the oil companies.

Dandelion chemistry: diuretics and the tires of the future – Redeeming qualities of what we normally consider weeds that are menace! I’ve come to appreciate them more over the years because they are edible (my grocery story has the leaves in their organic section occasionally) and their roots are deep enough to hold soil better than turf on a slope.

Infant formula: the superfood you never think about – One of my grandmothers discovered she was unable to breastfeed her babies….and that was well before commercial formula was available. Whatever recipe she used to create ‘formula’ worked. I suspect that one of the ingredients was evaporated milk. Her 9 children thrived…some into their 90s. What happened in the US recently with infant formula reminds us how dependent we are on modern technology that has become increasingly complex…and sometimes without enough redundancy/alternatives when failures occur.

Ancient tree in Chile could be the world’s oldest – A cypress that could be more than 5,000 years old.

Hot-blooded T. rex and cold-blooded Stegosaurus: Chemical clues reveal dinosaur metabolisms – Honing the analysis of how quickly they could turn oxygen to energy.

Under Water and Under Pressure – 100 national parks are coastal…and are already taking action to mitigate sea level rise.

Where do ‘Hawaiian box jellies’ come from? – Evidently the box jellies appear close to shore like clockwork 8-10 days after full moon. This research reveal that the jellies are spawning during that time…and where they are when they not close to shore. This is important for providing better information to ocean swimmers and beach goers…trying to avoid stings. Another benefit…learning to keep the food web balanced to control box jelly numbers in Hawaii and other tropical localities.

Stirring up a mid-Atlantic bloom – Lots of nutrients flowing into the water from the coastal watersheds during spring rainstorms.

Vancouver requires gas stations & parking lots without EV chargers to pay $10,000 per year – Interesting idea…hope it increases the number of chargers and the trend to EVs!

Photography In The National Parks: More Favorite Places For Photography - We’re not going to be traveling to any of the western parks near term….so I enjoyed them through these photographs: Crater Lake, Redwood, Yosemite, Great Basin, and Lewis and Clark (Washington state portion).

Maya tooth treatments may have prevented infection – In the Mayan world - holes were drilled to attach stones to teeth; an analysis of the sealant used for 8 teeth from across the Maya empire (AD 200-900) revealed that most sealants included ingredients from pine trees that have been shown to fight the bacteria that cause tooth decay.

Top 25 birds of the week: Forest Birds – I always like bird pictures….

Scientists recreate Cleopatra’s favorite perfume – Recreating Mendesian perfume…the result so far has been a strong, spicy, faintly musty scent that tended to linger longer than modern fragrances…with ingredients like desert date oil, myrrh, cinnamon, and pine resin.

Grand Canyon of Texas – I remember (tent) camping in Palo Duro Canyon in the 1970s on the way to Colorado…being very hot and worried that our tent was too close to a red ant bed! At the time, I didn’t realize that it is the second largest canyon in the US (behind Arizona’s Grand Canyon).

Why humans get less sleep than other primates – A different type of sleep research…teasing out the differences in sleep of humans and other primates….and between non-industrial human populations and industrial human populations. It turns out that in the human populations…the hours of sleep are about the same but the perception of getting enough sleep is higher in the non-industrial populations than the industrial ones!

Restoration Reveals Engravings in Egypt’s Temple of Esna – Follow the link at the top of the post to see a few more pictures of the restored engravings.

What we are still learning about how trees grow – A new study finds that tree growth is limited by cell growth rather than photosynthesis which has been assumed to be the limiting factor previously. The models that predict how much carbon forests can absorb need to be updated.

Spring Flowers are Blooming Earlier in Greater Yellowstone – The recovery of detailed records made in the 1970s by Frank Craighead of when flowers bloomed is helping document changes…help restoration planners determine the best seed mixes for native plants…try to mitigate the impact of climate change.

Cutting air pollution emissions would save 50,000 US lives, $600 billion each year – Yet another reason to take actions to dramatically reduce air pollution.

Traces of an ancient watery world in Capital Reef – Satellite views of Capitol Reef National Park…and the story in the rocks.

Prehistoric feces reveal parasites from feasting at Stonehenge – A piece of trivia: beef and pork were spit-roasted or boiled in clay pots but the evidence of particular parasites in coprolites reveals that liver and lungs from an infected animal were consumed raw or undercooked.

Vangelis, famed film composer and synth pioneer, dead at 79 – I remember going to see Chariots of Fire when it first came out in the early ‘80s….and the unforgettable music. This obituary post includes a link to a YouTube video with the music.

How cranberries could improve memory and ward off dementia – I like cranberries…but eating a cup (equivalent) per day is a lot. In the study they used cranberry powder.

More heat, more drought: New analyses offer grim outlook for the US west – The latest seasonal outlook projects the drought to continue across virtually the entire American west through the summer. New research suggests that Colorado, Utah, and Wyoming will increasingly look like the Southwest as temperatures continue to rise.

New Mexico Wildfire Spawns Fire Cloud – A pyrocumulonimbus cloud formed; the vertical plume reached the tropopause….an altitude of about 12 kilometers.

Heatwaves are altering our everyday lives – The new normal but we aren’t very well prepared for it; there are some obvious adaptations that are needed – particularly to electrical networks. No one wants infrastructure to fail at a critical time.

Well-preserved iron age arrow discovered in Norway – The arrow was recovered from a glacier…iron arrowhead, sinew, tar, thread, shaft, and feather fletching was preserved. It is about 30 inches long.

Rigid waterproof coating for paper aims to reduce our dependence on plastic – Interesting…would be great if it could speed the transition away from plastic for food packaging particularly. The article said the chemicals break down over time into harmless components…but didn’t say how long that took.

Chemicals that linger for decades in your blood – So many chemicals introduced in my lifetime are probably still in my blood. I can remember the spraying of DDT for mosquitoes in the ‘60s….one instance particularly of the straying truck going down the farm road near my grandparents house as we played in the back yard. How much of my exposure do I still have…did I pass along to my daughter?

Ultraviolet light reveals radiant hidden beauty of flowers – A project during the COVID-19 pandemic…beautiful results.

Archaeologists Unearth 3,000-Year-Old Giant Statues in Sardinian Necropolis – Over 7 foot tall…with almost emotionless expression, blocky nose and deep-set eyes. The two found most recently were boxers but about two dozen others have been found since the mid-1970s: 16 boxers, 4 archers, and 5 warriors.

Top 25 birds of the week: May 2022! – Bird appreciation….a source of beauty in the world.

Disparities in natural gas leak prevalence in US urban areas – Why can’t pipeline companies do better…not wait around until regulation requires them to do it? We should be more critical of the companies that they are not actively reducing leaks in their pipelines.

Why human brains were bigger 3,000 years ago – Some possible explanation: human populations reached a large enough size to share/divide labor and knowledge with others, writing….however, brain size/IQ relationship is not deterministic.

Operating rooms are the climate change contributor no one’s talking about – The health care industry accounts for 8.5% of all greenhouse gas emissions in the US. Operating rooms represent 70% of waste in hospitals and 3 to 6 times as much carbon as the rest of health systems.

Where tornadoes strike most frequently is changing – More erratic tornado activity and the broad impacts of climate change.

Do you have a lost twin? - The rate of twins among live births is only about 1.3%. But as many as 12% of all naturally conceived pregnancies may begin as twin pregnancies.

Wild fox kills 25 flamingos and a duck at National Zoo – We see foxes in our neighborhood. They seem to have adapted to the suburban environment. This one was very efficient to kill 25 birds, though.

Better residents’ health after switch to electric buses – A study from Sweden. Improved health is a benefit of electrification of transportation!

Should people get rid of their yards? – Somewhat depressing conclusion: “Most people would rather make an aesthetic choice with their lawns than an environmental one.” My plan is not to eliminate the yard in my new house but to minimize it over time with the addition of bushes along the fence and extending beds around trees and around the house.

We talk the fastest growing green jobs with LinkedIn Sr. Editor – The “job vs the environment” is changing. The “green economy’s ability to expand job opportunities is too significant to ignore.” This growth in green jobs is like the 1970s for computer related jobs – a lot of new types of jobs and many of them will extend for the duration of a career starting now.

The Great Barrier Reef through Time – Landsat Images used to illustrate recent research on the growth of the reefs as the ocean changes. Evidently the reef has been more resilient to past sea-level and temperature fluctuations than previously thought….but increased sediment input has been a bigger problem.

Harriet Tubman Byway/Blackwater National Wildlife Refuge

The 2nd of 4 Delmarva Birding field trips was Birding the Harriet Tubman Byway. It was a mixture of cultural and natural history of the area around Blackwater National Wildlife Refuge and Cambridge, Maryland – an area Harriet Tubman knew well as she was growing up and returned to after she escaped slavery to help others make their way to freedom. There is a map of the byway available from the Harriet Tubman Underground Railroad Visitor Center (we stopped there before the field trip…great orientation for the cultural history portion of the field trip) of the sites along the byway; our field trip visited a handful of them with excellent guides. From a natural history perspective - two species that are gone for the scene that she would have known are the American Chestnut and Carolina Parakeet.

The birding at Blackwater NWR was spectacular – just as every time I visit the place; it is where I saw my first Bald Eagle in the wild (in 1990 when my daughter was a baby). This year there were several Bald Eagle pairs that are nesting at the refuge. At one nest, the babies had evidently just been fed and were sleeping off their meal; the adult was still at the nest watching over them.

Osprey are making use of the nesting platforms and snags. There are more snags that ever because the water level is rising at the refuge…killing more trees that remain standing for a few years.

The muskrat mounds in the marsh were numerous. The color of the mounds is good camouflage for small birds. One of our guides commented that sometimes an eagle wll perch for a little while on a mound. If the muskrats are home…they probably go very still until the large bird leaves!

Rusty, the screech owl, is a well-known resident along the wildlife loop. The bird has a favorite perch in a pine with an hollow which provides protection for the bird’s back/sides. The hole where the bird might ‘live’ and raise young is in a nearby tree. The eyes moved while we watched but the bird was otherwise very still.

Somehow moss and pine needles seemed an appealing mini-landscape on the spring day.

Redwing blackbirds were noisy….defending territory…finding mates.

The field trip group continued into Cambridge to the courthouse – a place where the laws governing slavery in Harriet Tubman’s time were administered. The short lecture and conversation were thought provoking and heartbreaking. Fortunately, the field trip ended on a happy note at the nearby Harriet Tubman mural in Cambridge.

Stay tuned for my posts about 2 more Delmarva Birding field trips!

Meet the Eastern Phoebe, the flycatchers that coexists with humans – It’s always easier to hear this bird than see it! We have one that visits our backyard almost every morning this spring.

A community of seed savers has a recipe to revive rare varieties of collard greens – I became a fan of collards in my CSA share…now I am thinking that I might try planting an heirloom variety! I like them better than kale because the big leaves are flatter – easier to roll and the cut to make slaw…or as a last ingredient into a stir fry.

U.S. has warmed by 2.6 degrees F since first Earth Day – This was my first look at this metric. Maryland is bright orange (3 degrees increase) and Missouri is white (1.5 degrees increase). Maybe another aspect of my move to Missouri could be climate related migration!

The US will phase out incandescent light bulbs – Ban takes effect in 2023…but lots of people have already made the transition to the more efficient bulbs.

Picturesque clouds of Greenland – Cloud streets and vortices.

22% of new cars in Europe have a plug! – Hurray! Hope the US will catch up sometime soon.

Wildflower Fungi – This post was from the Master Naturalist group in Springfield MO. I am paying more attention now that I am moving to the area.

Deforestation drives climate change that harms remaining forest – Deforestation causes changes in a regions air temperature and precipitation…instigating changes in the whole region rather than just the part where the forest was removed.

Scientists Identify 50,000th Spider Species on Earth—but Thousands More Are Waiting to Be Discovered – It’s humbling to realize that there is so much about our world that we don’t know….have not discovered.

Amid Hopes and Fears, a plastic boom in Appalachia is on hold – Another sad trend in Appalachia…still hitching their future to fossil fuels. The jobs look good but the long-term jobs are few and the market for their products is not a positive one. Everyone wants to reduce single use plastics as much as possible.

Study suggests tree-filled spaces are more favorable to child development than paved or grassy surfaces – Playgrounds need more trees!

Purple gallinule with chicks – I remember seeing an adult purple gallinule on a birding field trip in Florida. Aren’t the chicks cute? Little black fluffs.

Reproductive factors and dementia risk – Hurray! My life events skew toward reduced dementia risk…according to this study.

Macro photos reveal the often unseen beauty and diversity of slime molds – Hmmm…maybe I should hone my observational skills to find these on my next hike…attempt some macro photography of them.

As EV Sales Soar, Automakers Back Higher Fuel Standards – So glad that industry is finally onboard…projecting a ‘we can do it’ attitude. I’d rather society take action…build some optimism into our view about the future rather than being depressed by trends that seem dystopian.

Beginner’s Tips for Identifying Backyard Bird Nests – It’s the nesting time of year! Look…id…don’t disturb!

Ozone may be heating the plant more than we realize – We’ve been concerned about ozone in the upper atmosphere for years (hence the Montreal Protocol) but this study also points to ozone in the lower atmosphere (caused by chemical reactions between pollutants like vehicle exhaust fumes and other emissions) as contributing to climate change as well. Until now, we thought of lower atmosphere ozone as a health problem (I get headaches if I am outdoors on a high ozone day, for example). This research says that it also is contributing to climate change by affectioning ocean heat uptake.

American Lung Association Says EVs Save Lives – Good for our health….and also for the planet. I also noted that where I live now is in the American Lung Associations Tops 10 US urban areas at risk from airborne pollution…another reason to move away from this area!

New Technology Employed to Protect Pompeii – A four-legged robot used to gather data on structural and safety issues.

Flamingo that escaped from a zoo in Kansas is spotted once again in Texas 17 years later – The flamingo is a species from Tanzania….and must be a very lonely bird.

Brain charts for the human lifespan – Normative trajectories derived from over 100,000 MRI scans that allow quantification of individual variation. Figure 1 in the post can be enlarged by simply clicking on the image.

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.

Winners of Wildlife Photography Competition Show the Power of Water – Starting out the gleanings list with some eye candy this week.

Personality traits are associated with well-being and satisfaction in life after work – My husband and I have transitioned to ‘life after work’ and seem to have easily established ‘new fulfilling life patterns.’ In an odd way, the COVID-19 pandemic has helped us focus on the most important aspects of those patterns.

A New Study of the Permian Basin – a US oil-drippling hotspot is kicking out far more methane that we thought – I keep thinking that the technology to reduce emissions in the fossil fuel extraction process has improved from the early days. Maybe it has…maybe the hasn’t. The industry may not be motivates. Is it all about maximizing profits for them and their stockholders…everyone else doesn’t matter?

Toad Wisdom – A story of webs of life from the Prairie Ecologist.

European earthworms reduce insect populations in North American forest – Even small invasive species can have a significant impact.

Mapping Inequality – Redlining in New Deal America – An introduction….then downloads and data for maps for urban areas across the US from the 1930s.

Top 25 birds of the week: birds on flowers – Enjoy some photographs of birds…flowers…springtime!

Scents help researchers identify contents of Egyptian vessels – The smells of ancient Egypt!

Norway at new record high 92% plugin EV share in March – Hopefully the EV share in the US will start climbing more rapidly.

“Flash droughts” coming on faster, global study shows – Extreme weather….not all on the wet side.

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.

Where Have All the (Big) Cypress Trees Gone ... And Are They Coming Back? – The cypress stands survived logging but they may never again be as dominant as they were before. The largest trees now are about 3.5 feet diameter; the largest stumps from logging are about 5 feet diameter.

8 bird migrations, from past to present – The annual movement of birds is a part of spring….part of the yearly progression.

Cherry Blossom Time In Washington, D.C. – I was glad to get home in time to see the cherry tree in our yard bloom; it’s a little behind the trees in DC (we are a little north and not on the water).

Nature Conservancy to build solar farms at abandoned coal mines in Virginia – And thus an energy producing community, continues…leaning into the future!

The sound of Merlin: like Shazam, but for birds – An app that IDs birds by their songs…a learning experience to take on a walk.

Higher risk of temperature-related death if global warming exceeds 2°C – We’ll have to be more aware of heatwaves. Perhaps we would modify our behavior during those times…and medical interventions might help. There is a heat threshold above which our bodies are not adapted very well…that will cause increasing problems.

Rarely Seen Paintings by J.R.R. Tolkien Portray a Lush ‘Lord of the Rings’ Landscape – Another perspective of Tolkien…through his art rather than writing.

No breathing easy for city dwellers: particulates – Southeast Asia has seen the largest annual average increases in concentration and mortality rates between 2000 and 2019 from this type of air pollution.

How climate change is leading to bigger hailstones – The records for the largest hailstones have been broken in the last 3 years in Texas, Colorado and Alabama….reaching sizes of up to 6.2 inches in diameter. Large hail causes a lot of damage…if the incidence of large hail increases the damage/costs will trend higher too; the post includes a picture of a car damaged by large hail…daunting to anyone that doesn’t have their car parked in a garage.

Missouri Man Indicted For Fire That Destroyed Ozark National Scenic Riverways Visitor Station – I am paying more attention to news about natural areas in Missouri…now that I am preparing to move to the state. It’s sad when this type of destruction occurs – hard to fathom why someone would burn a visitor station.

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 triple-pane windows stop energy (and money) from flying out the window – How long will it be before all window replacements and windows in new houses will be triple paned? I guess is depends a lot on affordability….and then availability. I like that they reduce noise too.

Yellowstone At 150: Challenges Go More Than Crowd-Deep – A post about Yellowstone’s past, present…projections for the future. My husband and I have only visited the park once…hopefully we’ll be able to see it again.

Beware the joro spider. Scientists say the giant, but harmless, arachnid is spreading – A native of Japan…it has been in the southeastern US for the past decade. It may be poised to continue up the eastern seaboard. Fortunately, they are not lethal to humans and the eat mosquitos/stink bugs.

Top 25 birds of the week: Seedeaters! – We see some of these at our birdfeeders!  

Cognitive Bias Codex, 2016 – A graphic I had not seen before….very thought provoking.

Revealing an Ice Age Route of Indigenous Peoples – Vancouver Island…analyzing lake sediments. One of them, Topknot Lake, was evidently never covered by glaciers so the sediment was very deep.

Hidden dangers lurking in your kitchen - A little history…and one that is relevant to my house hunting: I don’t want to buy a house with gas stove…if I do, it will be replaced with an electric ASAP.

Common house plants can improve air quality indoors – Modern homes are more airtight than ever…and indoor air quality can become a problem. Good to know that plants can help – and they are generally aesthetically pleasing too.

Spring is starting sooner and growing warmer – (A color coded map) Almost the whole US is experiencing earlier Spring. A small area of North and South Dakota is the exception.

Here are the world’s 25 most endangered cultural heritage sites – The post is a summary from Smithsonian Magazine. More details are available from the World Monuments Fund. There are sites in Ukraine that are in danger from the war there – will probably be on the next list (Smithsonian post and article with pictures of the 7 Ukranian UNESCO World Heritage Sites.

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.

Why soil is a surprisingly noisy place – Wow! A whole new way of studying soil…listening to it.

Gas flares tied to premature deaths – A study done by Rice University environmental engineers with data from North Dakota and Texas. There are currently no limits to flaring, unfortunately. Why can’t we use the gas productively? It bothers me when we hear that we need more fossil fuels to observe the way the industry still is so wasteful and polluting.

Dying for makeup: Lead cosmetics poisoned 18th century European socialites in search of whiter skin – I had heard of lead makeup before…but never is this detail.

Top 25 birds of the week: forest birds – The only one of these that appears in the forest behind our house in Maryland is the Tufted Titmouse.

Study questions the role of vitamin D2 in human health but its sibling, vitamin D3, could be important for fighting infections – The labelling on foods fortified with Vitamin D does not say which type is used – hopefully it is D3. The supplemental Vitamin D I take is definitely D3.

The Prairie Ecologist – Photos of the Week – February 26, 2022 – Winter photography….it’s about over for us. Daffodils are up!

What is the best age to learn to read? – There is more variability that I realized…generally between 4 and 7. There is growing consensus that there is no reason to rush it. Learning language is key and often older children learn to read faster because their spoken language skills are greater.

Effects of noise on marine life – The study was focused on turtles and observed noise-induced hearing loss (sometimes temporarily) which hampers their ability to detect predators, communication, navigation, etc.

Rash-causing moths are spreading in Maine because of climate change – Browntail moths (native to Europe). I thought when I saw the headline that it might be about the saddleback caterpillar which is native to North America and has stinging spines that cause a painful rash. We had a specimen in the Brookside Gardens Wings of Fancy exhibit back in July/August 2018.

Study of algae in Acadia National Park lakes shows recovery from acidification – A success story…the Clean Air Act Amendments enacted in the 1900s are making a difference!
