Gleanings of the Week Ending July 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.

Extended maternal care central factor to human other animal, longevity – In species where offspring survival depends on the longer-term presence of the mother, the species tends to evolve longer lives and a slower life pace, which is characterized by how long an animal lives and how often it reproduces.

The 'gene deserts' unravelling the mysteries of disease - Less than 2% percent of the human genome is dedicated to coding for genes which produce proteins, while much of the remaining 98% has no obvious meaning or purpose. But scientists are slowly managing to accrue information about the ‘gene deserts’ apparent purpose and why they exist.

These Stunning Butterflies Flew 2,600 Miles Across the Atlantic Ocean Without Stopping – Painted Lady butterflies spotted in French Guiana where they are not usually found. Sequencing the butterflies’ genome revealed that they were related to African and European painted ladies – not North American. And looking at weather data revealed that wind conditions in the weeks prior to the sighting were favorable for the butterflies moving from Africa to South America.

Simple test for flu could improve diagnosis and surveillance - Fewer than one percent of people who get the flu every year get tested, in part because most tests require trained personnel and expensive equipment. The current version of new test is a low-cost paper strip that distinguishes between influenza A and B and subtypes H1N1 and H3N2. It works at room temperature…takes about 90 minutes. They are working to reduce the time to 15 minutes.

To Save the Red Knots, Look to Blue Carbon – Red Knots migrate over 9,000 miles to the Arctic to breed. Along the way they stop for meals of mussels and clams in coastal areas. This post highlights 6 projects from around the world that are restoring those area…for the red knots and the health of the planet.

Photography In the National Parks: Two Cave Parks Above and BelowWind Cave National Park and Jewel Cave National Monument. Full of ideas for photographing inside caves and above them! My first thought was to see if there is a trail that goes over the top of Sequiota Cave and Spring near Springfield MO (we did a boat tour of the cave last spring).

Surprising phosphate finding in NASA's OSIRIS-REx asteroid sample – Remembering when we went to the launch of the mission in September 2016.

Swift Parrots and the Heartbreak of Rare Species – Endangered Australian parrots…with only an estimated 500 birds left in the wild. “We conservationists bear witness to so much loss: of species, ecosystems, and the places we know and love. Often, it feels like we’re watching extinction in real time, powerless to stop it. But there is value in staring these losses in the face. Value in bearing witness to a rare parrot with an uncertain future, knowing full well I might mourn its extinction in a few years time. If the worst happens, at least I will have cherished it while it was here.”

A Big Picture of the US Housing Market - High interest rates, supply constraints and growth in home insurance premiums (particularly in states like California and Florida) are all driving housing costs. There is some news that’s more positive. Nearly 450,000 new apartments were finished in 2023, the highest rate in about three decades. However, average rents remain above pre-pandemic levels in most markets.

Sheep & Solar: A “Beautiful Symbiotic Relationship” - When solar farms use sheep instead of mowers for vegetation management, they minimize burning fossil fuels, and costs associated with labor are also reduced. Investment costs for a solar farm might include water tanks, troughs, a small water pump to fill the troughs, predator-proof fencing, and dividing into sections for rotational grazing. The sheep eat the tall grass, weeds, and clover, and their chomping inhibits the vegetation from blocking the panels. Their steady consumption of forage on the land prevents grassy plants from growing high enough to block sunlight from reaching the panels, maintaining the productivity of the array. Sheep are the most appropriate ruminant species when it comes to vegetation management on solar farms because they are too small to damage the panels when rubbing against them, and they are not predisposed to chewing on wires or jumping on the panels.

Brookside Gardens Outdoors – October 2019

There is plenty to see outdoors at Brookside Gardens during October. I started out looking for fall foliage. This had not been a good color fall here in Maryland overall because of the drought. I started seeing colors right away at Brookside; a little watering means a lot.

I found butterflies in one of the garden ‘rooms’ near the conservatory. Monarchs (Danaus plexippus) – probably migrating toward Mexico – were enjoying the nectar plants: asters and late season cone flowers.

A painted lady (Vanessa cardui) was also enjoying the asters.

A tiny skipper was there too.

It took several tries for me to get a reasonable photo of a Clouded Sulphur (Colias philodice). The butterfly seemed to be in motion almost constantly.

After photographing the butterflies, I continued my walk around the gardens…looking for and finding colorful foliage – oaks and maples and dogwoods. Sometimes there seemed to be a spotlight of sun on just what I wanted to photograph!

Gleanings of the Week Ending June 30, 2018

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 Mysterious Demise of Africa’s Oldest Trees - Yale E360 – Baobab trees that are over 1000 years old are dying quickly…and there is not yet a definitive explanation.

History and Seaports in Charleston : Image of the Day – I visited Charlestown a few years ago on vacation…this picture from the International Space Station brought back memories and provided a different perspective of the place.

Top 25 Birds of Europe – National Geographic Blog – Last week it was Africa…this week it’s Europe.

New study examines impacts of fracking on water supplies worldwide - GeoSpace - AGU Blogosphere – Maps make it easy to look at complex data in a visual way. My take away from these maps of water supply and shale basin areas is that Texas has a lot of shale in areas that are already under water stress….fresh water is already being consumed unsustainably.

BBC - Future - Why non-smokers are getting lung cancer – I’ve wondered about non-smokers and lung cancer. The numbers are not huge…but they are often diagnosed late and are, therefore, more deadly.

Seventeenth-Century Danish Latrines Analyzed - Archaeology Magazine – Diet and parasites from more than 300 years ago.

Move Over, Monarchs: Another Butterfly Makes a Longer One-Way Migration - Yale E360 – Painted Lady Butterflies from southern Europe migrate across the Mediterranean through the Sahara to tropical Africa!

Discover Landscape Architecture Activity Books – THE DIRT – There are activity books for younger students and then teens/adults. I am reading the adult version and then will try to apply some of the activities when I travel…encourage new appreciation of the as-built landscape architecture of the places I visit.

2018 Lotus And Water Lily Festival At Kenilworth Aquatic Gardens – My husband and I don’t go to the festival but we do go the Kenilworth several times in July…expect lotus and water lily (and dragon fly) posts soon!

Lives before and after Stonehenge: An osteobiographical study of four prehistoric burials recently excavated from the Stonehenge World Heritage Site – Lifestyle rather than ethnicity seems to determine burial practices in this instance.

Bentsen-Rio Grande Valley State Park

The day after the Rio Grande Valley Birding Festival ended and before we headed back to San Antonio for our flight home, we visited the Bentsen Rio Grande Valley State Park. Our original plan had been to spend the morning at the National Butterfly Center in Mission, Texas but the morning was cold and wet…not conducive to butterfly activity. So we changed our plans. It was still cold and wet but some birds in the park didn’t care. This Northern Mockingbird called attention to itself with is song(s).

There was an area near the nature center with paved walkways – some of them intermittently covered. We walked around the area – everything was very wet.

We took the tram into the park and got off at the first stop. There was a small butterfly garden near the bird blind (where there was no action) and the rain held off for long enough for there to be a little activity. I spotted a Painted Lady,

A Skipper (not sure what kind),

Queens in abundance, and

We hiked a little further and came to another bird blind…and there was plenty going on there. A Golden Fronted Woodpecker enjoyed the suet.

The Plain Chachalacas were also coming in to the feeders for a snack.

Green Jays were around as well.

It started raining harder do we found a dry place to stand until the tram came bay again. There were more people on the tram for the return visit, so we got the seat on the back of tram…riding backwards. It was a good way to end our visit. I want to go back again on a day when the weather is better!
