Gleanings of the Week Ending December 18, 2021

December 18, 2021/ Gwen Morrison

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.

Monkeying Around with Venom – Hadn’t heard about ‘Snake Detection Theory’ before; it is the idea that snakes have exerted a selection pressure on the origin of primates’ visual systems, a trait that sets primates apart from other mammals. This paper is some recent research that supports the theory. A condensed description of the research paper is found here.

Why climate lawsuits are surging - Lawsuits are becoming tool to force change…in conjunction with activism, policy and science. There have been some successful lawsuits…and more in the pipeline. Sometimes the suit is about better enforcement of environmental laws…and sometimes it is about climate protection for future generations becoming a constitutional issue.

Florida to Feed Starving Manatees, as Pollution Shrinks Food Supplies – Florida farm runoff caused alga blooms that cut the penetration of sunlight into the water so much that it killed the seagrass that manatees eat…and there have already been more than 1,000 that have starved. It is estimated that there are about 8,000 manatees remaining in Florida waters. It is unclear that the seagrass can be restored.

Top 25 birds of the week: December 2021 – Enjoying bird photographs!

How volcanic eruptions helped the ancestral Puebloan culture flourish – Response of people to the stresses of abrupt climate change evidently resulted in larger population centers…universal pottery making and turkey cultivation…more sedentary living…increasing social inequity.

Major Contract Awarded To Rehabilitate Section Of George Washington Memorial Parkway – The parkway is along the Potomac River between Great Falls and Mount Vernon. It was one of the first beautiful and history things we discovered when we moved to the area in 1983…and long overdo for renovation. Parts of it carry a lot of daily commuter traffic in Northern Virginia.

The impact of drugs on gut microbes is greater than we thought – Most people are aware of the impact of antibiotics, but other drugs impact the gut microbes too…and some of those drugs are treating chronic conditions so are taken for years. It appears this study was mostly about methodology to tease out the impact of drugs vs the underlying disease….much more work still to be done before concrete recommendations can be made.

The race to make vaccines for a dangerous respiratory virus – RSV (Respiratory Syncytial Virus). There are currently 4 candidate vaccines and one monoclonal antibody treatment that are in last-stage trials. It appears we are at the cusp of much faster vaccine development times because of what happened to develop the COVID-19 vaccines.

The tomatoes at the forefront of a food revolution – The idea is to use Crispr modification to sustain the productivity of the tomato crop as the climate changes.

Chronic exposure to air pollution may increase risks for ICU admission or death among COVID-19 patients, study finds – Sometimes it is hard to separate the role of the environment on health disparities. This study analyzed 6,500 COVID-19 patients admitted to 7 New York City hospitals.

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.

Climate Change Responsible for Recent Decline of Eastern Monarch Butterflies – I know that the milkweed in my Maryland yard is not as healthy looking and I don’t see as many butterflies as I did in the 1990s…it’s a sad trend.

Top 25 birds of the week: July 2021 and Perching – A special treat – two collections of bird photographs in this gleanings post!

The parenting penalties faced by scientist mothers – There are no single or quick ‘fixes’ – moving forward requires thoughtful approaches. The status quo is not acceptable or sustainable!

True Grit: Adventures in Red-Cockaded Woodpecker Research – My husband and I saw red-cockaded woodpeckers in Florida during a birding festival field trip…so I tend to look at articles that appear in my news feed about them.

Florida Breaks Annual Manatee Death Record In First 6 Months Of 2021 – Florida seems to be a less appealing place to visit these days. Manatees were an animal my husband and I always wanted to see there and now they are starving to death because the seagrass (their food) is dead or dying in polluted waters. Other animals are probably impacted as well.

Chaco Culture National Historical Park: Hard To Reach, Filled With The Unexpected – I’ve only been to Chaco Canyon once….in the spring when it wasn’t overly hot. There were not many people on the windy, cool day we were there. The sounds of the place increased the sense of history in the ruins.

Air pollution during pregnancy may affect growth of newborn babies – There are so many aspects of the human impact on our environment that overwhelm what our bodies can handle…we should probably assume that there will be health impacts – particularly noticeable in the very young and the very old.

Burrowing Owls Face an Uncertain Future – They need holes from small colonial mammals….areas that are not plowed.

U.S. Power Sector Sees Biggest One-Year Drop in Emissions in More Than Two Decades – Picking up the pace as more renewables come online.

‘Inflammation clock’ can reveal body’s biological age – Maybe this turns out to be a good diagnostic to prompt interventions to extend healthy lifespan (via treatments on specific types of inflammation).

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.

Top 25 birds of the week – June 2021! – The first picture startled me – a bird with a turquoise beak!

Beach Safety Tips: How To Avoid Being Bitten or Stung This Summer – I’m don’t go to the beach frequently…and then am usually more interested in shells and ghost crabs than being in the water! Still – the safety tips were interesting.

Concrete: The material that defines our age – With the collapse of the reinforced concrete building in Florida….this story seemed particularly timely.

Edible Cholera vaccine made of powdered rice proves safe in phase 1 human trials, study suggests – Reminded me of distribution ease of the polio vaccine sugar cubes back in the 1960s. In this case the special rice is powdered and sealed in aluminum packets that are then mixed with 1/3 cup liquid and drunk. Hopefully, the subsequent phases of the trials will be successful…it could save a lot of lives.

Yellowstone and Warming: An Iconic Park Faces Startling Changes – A few degrees makes a big difference….in National Parks too.

Scientists Find Toxic ‘Forever Chemicals’ in More Than 100 Popular Makeup Products – I hope manufacturers of makeup will check their ingredients more carefully….make their products PFAS-free.

Canada is right to classify single-use plastics as toxic – I hope the US takes similar action. Industry should get on board with this idea and be innovative rather than taking legal action. There is no ‘responsible plastic use’ for single use plastic. We consumers are too accepting that single use plastics are inevitable. It’s pretty easy for us to avoid singe use plastic bags, straws, stirring sticks, six-pack rings, plasticware….the one that is challenging for me is the hard-to-recycle food containers because of the lack of options in grocery stores and restaurant takeout.

Move Over Bald Eagle: Meet 12 of the World’s Coolest National Birds – Some are flashy…some are majestic….a little history of how they were selected aa representatives for their country.

Losing Ladybugs – Native and non-native ladybugs….you are more likely to see the non-natives now.

Florida’s Manatees Are Dying at an Alarming Rate – Starving because water pollution (nutrient runoff causing algal blooms) smothers seagrass. More than 10% of the manatee population of Florida has died so far in 2021. Very sad for other aquatic species that need the same habitat … and people too.

Filling a Day of Social Distance – 4/8/2020

April 09, 2020/ Gwen Morrison

Continuing the blog post series prompted by COVID-19….

Here are the unique activities for yesterday:

Hearing the phoebe first thing in the morning. I am hearing a phoebe outside my office window every morning as I begin my day. Maybe it’s in the sycamore. Maybe its nest is nearby. I know from the time that the sun has just come up this morning but the clouds are hiding it; it’s too dark too look for the bird and try to get a picture.

Cleaning off the covered deck furniture. With the temperature forecast to get into the 70s in the afternoon, I cleaned off the table and chairs on the covered deck in the morning so I could spend time there in the afternoon. Everything was very dusty since it hadn’t been used over the winter. The furniture is over 20 years old and had been on the covered deck since we got it. It is undercover but ‘outdoors’ and I noticed there are some bubbles in the paint on the metal parts. It probably needs to be sanded down, primed, and repainted…which I am not enthusiastic about attempting.

2020 04 IMG_8815 (1).jpg — **Walking the neighborhood.** The forecast here is for cooler/wetter/windier after today so I wanted to get out and enjoy the sunshine…look around the neighborhood. Things change fast in the spring. Our cherry tree lost most of its petals overnight when thunderstorms rolled through. Most of the petals were on the ground. At another house the driveway was polka dotted with petals.

2020 04 IMG_8815 (4).jpg — The azalea still just has buds (and the deer have browsed the bush so there are not very many buds left).

A neighbor has a deciduous magnolia in bloom and it held its flowers in the storm.

2020 04 IMG_8815 (7).jpg — There is another tree blooming nearby. A fruit tree?

I recognized the redbud. ‘Cauliflory’ is a recent vocabulary word I learned from a tree tutorial; it means that the flowers are on branches and trunk…not where the leaf buds are…and that is how redbuds bloom!
