Gleanings of the Week Ending January 6, 2024

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 Britain's taste for tea may have been a life saver - The explosion of tea as an everyman's drink in late 1700s England saved many lives - the simple practice of boiling water for tea, in an era before people understood that illness could be caused by water-borne pathogens, may have been enough to keep many from an early grave. Sometimes people's existing behaviors can make more of a difference to their health than an explicit intervention might.

Carbon-Based Paleolithic Paintings Found in France - The carbon-based drawings were detected with visible light and infrared photography, X-ray fluorescence, and spectroscopy underneath previously known images. The discovery could allow for precise radiocarbon dating of the artwork. Most of the Paleolithic paintings in the more than 200 caves in the region were made with iron and manganese oxides, which cannot be directly dated with radiocarbon dating technologies.

Winners of the 2023 International Landscape Photographer of the Year Contest – Wonderful views. I wish more of them were annotated (where they were taken…comments from the photographer, etc.). One of my favorites was the Winner for Snow and Ice by Thomas Vijayan of Canada.

Which zoo animals are most active in winter and what times are best to see them? – Author commenting about zoos in the UK…but most of the comments are relevant to zoos in the US too. I particularly enjoyed the last recommendation – going to the Reptile House to warm up! My daughter gave us a membership to the local zoo for Christmas…and we’ll probably bundle up and go soon (but not while the weather is in the 20s)!

Photos of the Week – December 24, 2023 from the Prairie Ecologist – Great reminders that there are interesting subjects for nature photography in winter.

103-Year-Old Artificial Christmas Tree Sells for Over $4,000 – A sliver of history: The tree originally belonged to Dorothy Grant, whose family purchased it for their Leicestershire, England, home in 1920. When she first saw it, the 8-year-old girl was “wildly excited.” She decorated its branches with cotton wool that resembled snow, as baubles were an “extravagance” at the time. Grant cherished the tree for the rest of her life. When she died at the age of 101 in 2014, her 84-year-old daughter, Shirley Hall, inherited it. She decided to part with it to honor her mother’s memory and to ensure it survives as a humble reminder of 1920s life—a boom-to-bust decade.

Photography In the National Parks: 2023 In Review – Rebecca Lawson’s favorite shots from 2023 from Yellowstone, Glacier, Mount Rainer, Lake Chelan, Yosemite, Death Valley, and Banff National Parks.

Honeycrisp, Cosmic Crisp usher in banner year for U.S. apples - Growers report that apple production in the United States hit levels in 2023 that had not been seen since the 2014-15 season. Washington State was the largest grower, producing some 90% of the nation's crop. Of all the varieties, Honeycrisp, Gala, Red Delicious, Granny Smith and Fuji make up 76% of the total apple holdings. The big winner this year was the Cosmic Crisp apple, which experienced a 41% year-over-year growth, with 9.5 million bushels harvested.

Millions of mysterious pits in the ocean decoded - Most of the depressions in the seafloor in the German Bight are created by porpoises and other animals in search of food, and then scoured out by bottom currents. The researchers showed that the marine mammals leave pits in the seafloor when they hunt for buried sand eels.

2023 was a year of big anniversaries – 20 years ago the space shuttle Columbia disintegrated over Texas…the Concorde made its final flight, 30 years ago the World Wide Web launched into the public domain, 50 years ago hip-hop began, 60 years ago March on Washington for Jobs and Freedom (“I have a dream” speech)…JFK assassinated, 75 years ago Israel declared independence, 80 years ago Casablanca opened, 150 years ago blue jeans patented.

2023 at Hagerman National Wildlife Refuge

I made stops at Hagerman National Wildlife Refuge on my way to and from Carrollton all during the year. On the way down, I arrived around noon; on the way home, it was just after sunrise.

Seeing/photographing birds is the big draw for my visits. I spend an hour or so moving slowly down the central wildlife tour road…sometimes taking a side road. I use my car as a blind and roll the window down when I see birds. My camera is on a monopod collapsed down to its shortest length. Most of the time I brace it in the cup holder between the front seats…tilt the head to get the image I want.

In the winter there are flocks of snow geese (and Ross’s geese) along with Northern Shovelers and Pintails. White Faced Ibis and American White Pelicans are seen during migrations. Egrets (snowy, cattle, great) are numerous in the spring and summer; I enjoyed an early morning seeing/hearing them on one of the ponds where they had obviously spent the night. Great Blue Herons are around all the time although are most numerous in the summer when the young are beginning life on their own. Red-winged blackbirds are year-round residents but murmurations of the birds are seen in the fall as they move about eating the mature seeds of the prairie plants. I saw Neotropic Cormorants for the first time this year.

Of course there are other things to photograph too – prairie type flowers, drift wood, insects, sunrise. This year I noticed a cluster of Queen butterflies in July…didn’t see many Monarchs until the fall when they were probably migrating. The butterflies were photographed in the butterfly garden near the refuge’s visitor center – along with a grasshopper! I was surprised to see a dragonfly perched on a plant so close to the car that I was able to photograph it during my drive down the wildlife loop!

Hagerman has become one of my favorite places in Texas…and I will continue to stop there as often as I can.

20 Incredible Winners From the 2023 European Wildlife Photographer of the Year Contest – Lots of natural beauty…captured in photographs.

A known environmental hazard can change the epigenetics of cells – Formaldehyde. It is a widespread pollutant - formaldehyde enters our body mainly during our breathing and, because it dissolves well in an aqueous medium, it ends up reaching all the cells of our body. It is associated with an increased risk of developing cancer (nasopharyngeal tumors and leukemia), hepatic degeneration due to fatty liver (steatosis) and asthma.

How forest schools boost children's immune systems – It seems the benefits go well beyond immune systems.  Hopefully this type of school for 3 to 5 year old will increase in availability/popularity.

Circular Maya Structure Uncovered in Southern Mexico - Similar round structures have been found at the Maya sites of Edzná, Becán, Uxmal, and Chichen Itzá.

Health Care Workers Are Burning Out, CDC Says - The CDC researchers analyzed self-reported symptoms of more than 1,400 adults in 2018 and 2022 who were working in three areas: health care, other essential services and all other professions. Workers’ self-reported poor mental health days in the past 30 days was similar across all three groups in 2022, but health professionals saw the most significant jump, from 3.3 in 2018 to 4.5 in 2022. Reports of harassment at work also spiked among health care workers over the five-year period, going from 6.4 percent to 13.4 percent.

How To Bring Back the Prairie, a Tiny Bit at a Time – The use of “prairie strips” on farms in an effort to restore a portion of the Minnesota’s remnant prairie and to soak up polluted water.

These Ten Stunning Images Prove That Small Is Beautiful – From Nikon’s Small World Photomicrography Contest. My favorite was the cuckoo wasp.

Deforestation in Colombia Down 70 Percent So Far This Year - Since taking power last year, leftist President Gustavo Petro has enacted a slate of new policies aimed at protecting Colombian forests, including paying locals to conserve woodland. The recent gains in Colombia mirror similar advances in the Brazilian Amazon, where leftist President Luiz Inacio Lula da Silva has cracked down on forest clearing; deforestation is down 50 percent through the first nine months of this year. In 2021, more than 100 countries, from Brazil to Russia to Indonesia, set a goal to end deforestation by the end of this decade, but so far forest loss has declined too slowly to stay on pace for this target.

European wildcats avoided introduced domestic cats for 2,000 years – About 50 years ago in Scotland, however, that all changed. Perhaps as a result of dwindling wildcat populations and a lack of opportunity to mate with other wildcats, rates of interbreeding between wild and domestic cats rose rapidly.

Why grazing bison could be good for the planet - The shortgrass prairie makes up 27,413 sqare miles of remote land straddling the US/Canadian border to the east of the Rocky Mountains. This rare habitat is in ecological decline. Plains bison co-evolved with the short-grass prairie. In the 12,000 years since the end of the Pleistocene, they have proven themselves to be potent ecosystem engineers. An adult bison eats about 25lb (11kg) of grass a day. The grasses adapted to their foraging. Vegetation across the plains uses the nutrients in their dung. Birds pluck their fur from bushes to insulate their nests. Bison also shape the land literally. They roll in the dust and create indentations known as "wallows" that hold water after rainstorms. After the bison move on, insects flourish in these pools and become a feast for birds and small mammals. Pronghorn antelope survive by following their tracks through deep winter snows. Replacing cattle with bison greens floodplains…setting the stage for beavers.

Extreme Weather is the “New Norm” - There is high confidence that human induced climate change from greenhouse emissions, is the main driver.

A Visit to North America's Only Authenticated Viking Site - L’Anse aux Meadows National Historic Site (in Newfoundland), the only authenticated Viking site in North America. Credit for this discovery in the 1960s goes to Norwegian explorer/writer Helge Ingstad and his archaeologist wife Anne Stine.

Earth’s hottest month: these charts show what happened in July and what comes next – The intense heat this summer has killed Saguaro cactus!

Ötzi the Iceman’s Genome Sequenced – 90% of his ancestry came from Anatolian farmers. Genome analysis revealed he had high skin pigmentation, dark eyes, and male pattern baldness!

Common wristbands 'hotbed' for harmful bacteria including E. coli, staphylococcus – I am glad the band on my Garmin is metal since it likely harbors a lot less bacteria than a plastic, rubber, cloth, or leather band. However, I still need to get in the habit of cleaning it more often.

Fully Intact Giant Panda Skeleton Discovered in Chinese Emperor’s 2,000-Year-Old Tomb – There was also an Asian taper in the tomb.  The article suggests that perhaps the animals were included in the tomb as a part of a replica royal garden.

Medications for chronic diseases affect the body's ability to regulate body temperature, keep cool - Medications used to treat common chronic conditions, like blood thinners, blood pressure drugs, Parkinson's disease/Alzheimer's medications, and some chemotherapy drugs, can make it harder for the human body to handle hot weather by reducing its ability to sweat or increase blood flow to the skin. Hopefully doctors will become more aware of this issue – particularly for their elderly patients that are already at increased risk because of their age for heat related issues.

Trapped: Australia’s extraordinary alpine insects are being marooned on mountaintops as the world warms – The grasshopper with the turquoise exoskeleton snagged my attention. This movement up mountains and then becoming marooned must be happening around the world.

Chromium replaces rare and expensive noble metals – Osmium and ruthenium replaced with, much more abundant, chromium? More research is needed, but it might be possible.

Photos of the Week – August 13, 2023 from the Prairie Ecologist – Another example of enjoying some photography even when it is hot and humid!

Pocket Prairie/Josie Ranch

When I was in Carrollton, Texas in late April there were a lot of rainy days…but I managed a brief visit to the Josey Ranch area one morning. The Pocket Prairie area suffered last summer and the gardeners have done work to restore it this year. A bluebird was sitting on a post as I got out of my car…a great start to my visit.

A few flowers were beginning to bloom. I could tell that the rain garden area was planted to be better than ever.

When I retraced my steps toward the car, I noticed Canada Geese in the distance: a pair with 5 goslings! Hopefully everyone will give them space…avoid being attached by the parents!

The lake seemed relatively empty…between seasons. There was a Great Blue Heron preening in the shallows. The cattail area that had dried out last summer seems to be back to its normal watery condition.

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.

Tallgrass Prairie National Preserve: A windo into the past – A prompt for an early fall road trip? It is about 4 hours from where we live now.

Psoriasis: Study lays foundation for new treatment strategy – Hope more targeted treatment can be developed….avoiding the drugs used currently that suppress the immune system overall.

Winners of the 2022 Audubon Photography Awards Celebrate the Beauty of Our Feathered Friends – Images of birds in action.

The silent danger of gum disease – More reasons to sustain regular dental checkups….and for dentists to be vigilant.

The Milkweed Gang – Milkweed attracts quite a few insects…even if it is an island surrounded by invasive plants!

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!

This New Species of Carnivorous Pitcher Plant Traps Its Prey Underground – In the rainforest of Borneo at elevations of 3,600 – 4,265 feet.

Ozone Hole — New, Large, Constant Ozone Hole — Appears Over Tropics – 7x larger than then Antarctic ozone hole!

Unlocking the secrets of the ancient coastal Maya – More than a decade of interdisciplinary work increasing the understanding of how these people lived and responded to rising sea levels and changing political/economic systems. And still more to be learned.

Dramatic Short Film Explores the Secret World of Microscopic Plankton – Video and photographs…the beauty of the very small.

“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.  

Ancient ochre mine uncovered in Wyoming – Around 13,000 years ago, Paleoindians mined hematite at the site…and used it to produce red ochre.

Photos of the week – May 27, 2002 – Spring prairie flowers/seeds from the Prairie Ecologist.

What can and can’t be recycled – Thinking about recycling….now that I am moving to Missouri, I need to figure out the rules for curbside recycling. I already know there are some differences from Maryland.

Type 2 diabetes accelerates brain aging and cognitive decline – A scary result since there are so many people with type 2 diabetes….and currently doctors don’t have brain based biomarkers for type 2 diabetes or treatment strategies that target neurocognitive declines.

Fibromyalgia likely the result of autoimmune problems – Maybe this change in thinking (neurologic to immune system) will improve diagnosis and management of the disease.

How freezing changed the green pea – A little food history

Massive Antarctic Lake Vanishes in Just Three Days – A lot can be learned with observations from space…and once we see something interesting like this there is historical imagery that can provide a view from past years too.

Tuberculosis: The Forgotten Pandemic – The search for a better vaccine for TB….some history of the past 100 years of TB around the world.

Top 25 birds of the week: Bird Interactions! – Birds with others…of their own species and sometimes another bird species.

The Finalists of the Bird Photographer of the Year 2021 Are Announced – Just found this post that came out back in April…enjoy a double dose of bird photos in this gleanings list.

Photos of the Week – June 17, 2021 – Spider photos from The Prairie Ecologist

Fire Destroyed 10 Percent of World’s Giant Sequoias Last Year—Can They Survive Climate Change? – Very sad….and this year there could be more fires.

6 Surprising Tales of Predatory Birds – The 6 birds featured are: pelicans, great blue herons, turkeys, crows, kelp gulls, and vampire finches.

Coelacanths may live nearly a century, five times longer than researchers expected – An ancient form of fish that evidently lives a long time, reaches maturity at about 55 years old and gestates offspring for 5 years. This slow life history has implications for conservation of the fish. I also wondered how many other species we know only from fossils had slow life histories compared to organism we observe today.

Josey Ranch Pocket Prairie – July 2019

The Josey Ranch Pocket Prairie has gotten taller since I visited back in April. At first glance the dominant colors are greens and browns. It takes a closer look to notice the wild flowers that are still in bloom and the seed pods that many are already beginning to form. I thought about what it would be like to walk through a larger prairie – that continued for as far as the eye could see – it would not be an easy stroll. The plants are intertwined and densely packed. They are at least waist high. And there would be no shade from the heat. Streams large enough to support trees would be precious.

The flowers are like jewels in the greens and browns. I used the zoom to get flower pictures and stayed on the path. It was still early enough in the day that the temperature was cool, and I was the only one in the pocket prairie even though the morning commuter traffic was just yards away. I was alone but not too alone.

Kudos to the crew that established and maintain the Josey Ranch Pocket Prairie!
