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.

Dickerson Park Zoo

We made our first visit to Dickerson Park Zoo last week. It’s on the north side of Springfield MO – the closest zoo to where we live. We got there about an hour after their opening; the close parking lot was almost full…others taking the advantage of the cooler than usual August morning.

Colorful birds seem to dominate my pictures. Many times, I was photographing through fencing; sometimes you can see the blur/shadow of that barrier.

The preening Scarlet Ibis was one of my favorites. The surprise was seeing the nictitating membrane (an eyelid that is hinged on the inner side of the eye and closes horizontally across the cornea).

Flamingos were in the same enclosure as the ibis – feeding and preening. They feed with their bill toward their bodies. One of the birds had a range of colored feathers.

In the trees above the flamingoes, there were several roseate spoonbills. Their bodies are colorful…their heads and large bills are bare – at odds with the body.

Peacocks (and pea hens) roam the zoo; they are relatively acclimated to people. There were no males with full tails. All the birds I saw appeared to be juvenile birds (younger than 3 years).

There were two Gray Crowned Cranes. I had seen similar birds at the St. Louis Zoo too. The birds at Dickerson Park Zoo were better positioned for a photograph!

The turkey enclosure had one male and a lot of hens…some immatures as well. I heard a mother telling her child that it was a mom and babies; I guess she thought the male was the ‘mom’!

Black swans are dramatic. The pair seems to have more ruffled feathers than I expected.

There were several parrots; we heard them before we saw them! The one I photographed was using its beak like an appendage for balance as it moved around its enclosure.

There were two types of tortoises in different parts of the zoo with signage that they bite! The first one was large but not giant…and I was intrigued by the pattern of the shell…plates like flatted pyramids.

The second was a giant tortoise --- looking well fed!

There were monkeys – somehow they tend to look sad to me. The one I photographed had companions that were moving about, but he was sitting still.

The zoo was working on the giraffe exhibit (they usually have giraffe feedings) so we did not see them like they would normally have been out and about in the morning.

The zoo has a rescued bald eagle – large but one of its wings was not right. It didn’t move from its perch but kept a watchful eye on movements outside its enclosure.

There were metal statues for climbing on (with signs warning that the statues might get hot in the summer) and backdrops for photographs.

There was one elephant with the explanation that when the matriarch died, the two remaining females did not get along…so they each are outside on their own. They get socialization time off exhibit with a male elephant.

There were other animals to see but not easily photographed. The big cats and bears were either in their dens or sleeping.

We didn’t ride the train (I photographed it with a giraffe sculpture in the foreground) – but I like that it is available – another dimension to a visit to the zoo that we might try on a future visit.

The Dickerson Park Zoo might be my favorite. It is not overwhelmingly big or crowned…and its design provides plenty of shade along the paths.

St. Louis Zoo

After our visit to the Jewel Box, we spent the rest of the day at the St. Louis Zoo. We parked in the south parking lot and noticed the animal sculptures as we made our way to the bridge that leads to the zoo entrance.

The giant tortoises were out and the smallest one was moving about. I noticed one of the larger ones had a hole in its shell; was this tortoise shot at some point in its long life?

The Reptile House was one of our early stops beginning a big loop around the zoo (starting up hill first). The lizard peeking out of a tree in its habitat was one of my favorites.

At one of our first breaks, there were large catalpa trees with the long seed pods still green. It was good to see healthy catalpa trees again; my maternal grandparents had catalpas around their home and business in the 1960s --- seeing the trees triggered fond memories.

The Flight Cage is the oldest part of the zoo; it was built for the 1904 World’s Fair. There were quite a few birds in the large mesh-enclosed area.

One of my favorites was a wood duck. Was the eye injured or is that just the way a wood duck eye looks when it is closed/half open?

Leaving the flight cage – there are mosaics of natural areas.

Cranes were in habitats with other animals. I enjoyed getting different views of the one bird as it was feeding.

In the big apes area, my camera’s zoom managed to get a gorilla in the back of the habitat…looking serious and scratching his brow.

Flamingos and other water birds enjoy lakes with islands at the zoo…visible but able to get further away from noisy crowds. The pelicans are rescued birds (i.e. are birds that have a significant enough injury that they couldn’t survive in the wild).

I enjoyed the ways the zoo uses nature themes in their structures….and that they have solar panels too!

There is a carousel. It looked to be well-maintained but not busy when we were there (hence the pictures).

Of course – there is also ‘wildlife’ in the zoo that just finds the zoo a good place to be!

We enjoyed the people watching as much as the animals at the zoo. Some children obviously were locals familiar with the zoo and enthusiastically making their way to their favorite exhibits…couples with babies in strollers (with visions of the time their child would be old enough to make requests)…families clearly on vacation…older people – sometimes with grandchildren, sometimes as couples or small groups using the zoo as an interesting (and safe) place to walk.

It was a hot day and by about 3 PM we were ready for a cool down. We retreated to our hotel for a few hours before walking to a Lebanese restaurant for an early dinner. It was a day well spent.

Gleanings of the Week Ending April 8, 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.

Avi Kwa Ame, Sacred Land in Nevada, to Be Preserved as a National Monument – Good! Another place to see when we make a trip in the west.

Volvo Delivers Its 1st Electric Heavy-Duty Truck in Africa – The truck is being used for collecting waste in Rabat, Morocco. Morocco is also home to the world’s biggest concentrated solar power facility.

A 90-year-old tortoise named Mr. Pickles just became a father of 3. It's a big 'dill' – Radiated tortoise native to Madagascar and critically endangered…at the Houston Zoo.

One of Europe’s last free-flowing rivers declared a National Park – Albania’s Vjosa River. Europe is also removing dams along other river just as we are in the US…but rivers that have been controlled by barriers will never be the way they were before the dam.

Clinics on wheels bring doctors and dentists to health care deserts – It’s a step forward and might work well for preventative or chronic care…but what happens in cases where the need is more urgent…like broken bones, having a baby, the aftermath of a car accident?

Technology over the long run: zoom out to see how dramatically the world can change within a lifetime – A graphic from ‘Our World in Data’ – worth the look. See the big developments they selected occuring during your lifetime….and when technologies we take for granted came along.

Take a Virtual Tour of the ‘Doomsday’ Seed Vault – Its doors are only opened a few times each year for new seed entries. The seeds come from countries from all over the world and are kept at -18 degrees Celsius. The most recent withdrawal was to re-establish a seedbank that had been destroyed in Aleppo during the Syrian Civil War.

Urban Trees Could Cut Summer Heat Deaths by a Third – Increasing tree cover to 30% could reduce premature deaths from urban heat islands by 40%. Sounds like a good idea of heath…and makes the cities more appealing too. Other actions can help too: green roofs/walls, light colored roofs/walls/landscape pavers, and replacing impervious surfaces with plants and soils.

Fresh produce contaminated with toxic BPA-like chemicals found in food labels – A Canadian study found that the chemicals migrate from labels in packaging materials into the food!

Common sweetener suppresses mouse immune system — in high doses – An artificial sweetener (sucralose) that might become a drug to reduce or replace immunosuppressive drugs that often have a lot of unpleasant side effects (if humans react to it the same as mice).

Gleanings of the Week Ending June 29, 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.

Porcupines | National Geographic – I was disappointed that they didn’t include more pictures of the North American Porcupine. I’ve never seen one in the wild.

BBC - Future - How to build something that lasts 10,000 years – Specifically – this post is about building a clock that will last for 10,000 years…in West Texas!

Researchers uncover indoor pollution hazards -- ScienceDaily – Some surprises: pollutants change with temperature inside the house….and time of day makes a difference. Formaldehyde seems to be particularly prevalent. These studies are scary for existing homes. We need work on mitigations that homeowners can implement…and new construction that reduces the source of pollutants.

Infographic: Immunity Isn't the Body's Only Defense System | The Scientist Magazine® - Symbiotic bacteria, metabolism and pathogen mutation examples overlay the immunity strategy. As we learn more, we realize that the human body is more complex that we realized.

Top 25 Wild Bird Photographs of the Week: Blue – National Geographic Society Newsroom – So many blue birds!

Tortoises rule on Aldabra Atoll – Tortoises making their way through the huts where people bunked! The tortoises sleep with head and legs stretched out…no predators to fear on the inhospitable atoll.

Past climate change pushed birds from the northern hemisphere to the tropics -- ScienceDaily – Thought provoking. I wondered if some of the birds that now migrate from North America to Central or South America for the winter….will not go as far or will shift their range northward.  I suppose it would work if their food sources shifted and the birds followed the food. The synchrony of plants blooming and seeds ripening….of horseshoe crabs laying eggs…all while birds are migrating or getting ready to produce young; it’s not a simple system.

Making STEM Education More Welcoming to Underrepresented Minorities | The Scientist Magazine® - Education doesn’t happen in a vacuum that has well defined boundaries. We must do more than just academic support…I’m glad there is more research and conversation on how to move forward in tangible ways to make STEM education and careers more open to everyone.

An Ancient Asteroid Crater May Be Hiding Off Scotland’s Coast | Smart News | Smithsonian – Some recent work that points to a crater of a asteroid from 1.2 billion years ago.

Three Studies Track People's Microbiomes Through Health and Disease | The Scientist Magazine® - Interesting…but they could just be expensive association studies (a quote from the end of the paper). At some point, maybe the findings will lead to something that benefits the patient.
