Gleanings of the Week Ending April 1, 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.

Climate change threatens spring wildflowers by speeding up the time when trees leaf out above them – Evidently the trees and wildflowers in eastern North America are the ones getting the most out of sync.

The mystery of Alice in Wonderland syndrome (AIWS) – AIWS (or Todd’s syndrome) affects the way people perceive the world around them and can distort the way they experience their own bodies and the space it occupies. There are 40 types of visual distortions that characteristic of the syndrome. It was formally described as a distinct syndrome in 1955. Up to 30% of adolescents reported mild or transient experiences. Cough medicines and illicit hallucinogenic substances are also known to trigger it.  Sometimes medical conditions like strokes or brain tumors can cause the syndrome as can infections.

Chinook salmon fishing season canceled off coasts of Oregon, California – Dwindling numbers of Chinook salmon in the states’ largest rivers following years of drought.

In Florida, an invasive snail is helping save an endangered bird – We heard about this during a birding trip to central Florida pre-pandemic. It probably is one of the few examples when an invasive species has produced a positive outcome.

Garbage to Guts: The Slow-Churn of Plastic Waste – Lots of microplastics in the world…and they are in our food chain. Ongoing exposure decreases beneficial gut bacteria and increases pathogenic species. A lot more research needs to be done since, right now, we don’t know very much about impacts of microplastics – not just to the overall environment but to our own bodies.

 With Heat from Heat Pumps, US Energy Requirements Could Plummet By 60% - Thinking about heat….and the ‘rejected energy’ (mostly heat) in our current energy consumption. The idea is to use heat pumps to dramatically reduce ‘rejected energy’ in future energy consumption.

Entire populations of Antarctic seabirds fail to breed due to extreme, climate-change-related snowstorms – Evidently the December 2021 - January 2022 breeding season for south polar skua, Antarctic petrel, and snow petrel was so disrupted that there were almost no young produced.

Why don’t humans have fur – Interesting…but we really don’t know. The genetic research associated with the question could have practical application for people that need to stimulate hair growth (like after chemotherapy or balding).

2021 Was A Very Good Year for Nesting Wading Birds In The Everglades – Hurray! Some good happening in the Everglades. There are so many stories about the impact of invasive species (like Burmese pythons) that this is welcome news.

Meet the sargassum belt, a 5,000-mile-long snake of seaweed circling Florida - In the open sea, sargassum can soak up carbon dioxide and serve as a critical habitat for fish, crabs, shrimp, turtles, and birds…all positive. But when sargassum gets close to shore it can smother coral reefs, alter the water’s pH…and then onshore it begins to rot within 24 hours releasing irritants like hydrogen sulfide which smells like rotten eggs or manure and can cause respiratory problems. And it often contains significant amounts of arsenic so not a great addition to a compost pile. The mass of sargassum has been increasing since 2011 --- probably in response to elevated nutrients (runoff from fertilizer, burning biomass, increasing wastewater from cities, etc.) we have released into the ocean. Sargassum has come ashore in Yucatan and Key West recently.

Gleanings of the Week Ending July 30, 2022

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.

Furs from Danish Viking Burials Analyzed – Proteins extracted from animal furs found in 6 burials. The accessories/furnishings were domesticated animals. The items of clothing were wild beaver, squirrels, and weasels. The beaver furs were not native to the area so were probably luxury furs obtained by trade.

More Energy on Less Land: The Drive to Shrink Solar’s Footprint – Good ideas…if we must use agriculturally productive land for solar panels. I’d like to see cities with high density solar panels that generate electricity close to where it is needed (i.e., short distance between generation and use). Hopefully that is happening in parallel with the solar development described in this article.

Moths are unsung heroes of pollination – The study was done with red clover…but probably applies to a broader range of plants. Moths are active during the night so have not been as easily observed as pollinators that are active during the day. The work was done with time lapse cameras.

Electric School Buses! – A blog post about the US Department of Energy’s ‘Flipping the Switch on Electric School Buses’ series. There are lots of communities that have been exploring making the transition and I am hopeful that it will be an escalating trend. I always cringed at the fumes that were so obvious when the buses arrived/departed from schools as I was growing up and when my daughter was in school. It would be good for the planet and good for children’s lungs to eliminate the school bus as a source of air pollution!

The habits that help prevent allergies – Studies that are improving our understanding of why allergies are increasing in the children….and strategies for addressing the problem. Evidently the time between 4 and 11 months is very important.

Harm from blue light exposure increases with age, research in flies suggests – Not good news. Maybe the default setting on our ‘screens’ (phones, computers, television) need to reduce blue light rather than it being a setting that everyone must intentionally set. And why don’t LED manufactures offer bulbs that are not so blue shifted?

Giant Snails take over Florida’s Gulf Coast - It is not the first time…probably won’t be the last. These snails are native to Africa and this the third time Florida has battled an invasion.

Water resources to become less predictable with climate change – The study focused primarily on areas that rely on snow for all or part of their water supply. Some of those areas are already relatively dry…and the populations are large enough that the unpredictability of water resources will be very problematic.

The best way to brush your teeth – This is going to take some practice to break old habits. I learned to brush my teeth a long time ago and probably am too sloppy even doing it the way I was taught!

New thought on Cahokia’s ancient wetlands – A large flat rectangular area that was previously thought to have been used as open, communal space might have been under water most of the year!

Carrollton Yard – July 2021

2021 07 IMG_4882 (2).jpg

The back yard in Carrollton, Texas is a sunnier space that when I was here in May (a big tree had to be cut down). And it is summer. There are some cannas that are some of the tallest I’ve seen.

The hydrangeas are waning…the Queen Anne’s Lace is not as abundant as earlier…there are some round yellow-orange blobs of fungus in the shredded wood left from the big tree…they are almost the same color as the cosmos that are blooming in the newly sunny patch…a few Naked Lady Lilies and other shade loving plants are under the pecan tree which is growing rapidly now that the old mulberry is not overhead.

There are metal sculptures that I always notice among the plants – always there but looking different because of the changes of the plants over the season.

In the front yard, the ferns have spores forming on the underside of the fronds and there is only one daisy left.

The red yucca has seed pods developing among its flowers.

In a patch of dirt where some plant has died back, I found an large,empty snail shell…even though haven’t seen a snail in the yard before!

Overall – the garden in Carrollton has changed quite a lot since May. Having the big tree gone has changed things more than the usual cycle…this next year will be one of transition for the corner of the yard that was very shady and is now full of sun.

Gleanings of the Week Ending September 5, 2020

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 cavemen needed no braces – Our diet and behavior have changed a lot since the stone and hunter/gather stages of our species….and those changes have impacted our jaw (and teeth and air way). There are more health consequences than just crooked teeth. I’ve bought the book (Kindle version) to learn more.

Characteristics that give viruses pandemic potential – An article from The Scientist that is more future oriented. What we are experiencing with COVID-19 is something that could happen again. The article talks about various types of viruses that pose the greatest threats.

Peer into the Past with Photorealistic Portraits of Roman Emperors – Taking historical sculptures and drawings to the next level. The Smithsonian Magazine summary has images of Augustus, Maximus Thrax, Caligula, and Nero….the rest can be viewed in Daniel Voshart’s site.

Amazing Macro Winners of the International Garden Photographer of the Year 2020 – Visual treats. This it the type post that gives me ideas about things to try with my own camera.

1,200-Year-Old Soap Factory Unearthed in Negev Desert – The soap was made from olive oil and the ashes of the saltwort plant. The factory produced enough for export to places like Egypt and other parts of the Arab world.

Low humidity increases COVID-19 risk: Another reason to wear a mask – This finding does not bode well for the winter when many homes and workplaces have much lower humidity because of furnaces.

Top 25 birds of the week: Birds in Pairs – Beautiful birds….I always enjoy looking at the 25 pictures each week.

Hawaiʻian Snails: A Tale of Discovery and Rediscovery – I remember seeing a snail in a planter box at the airport on the big island while I was waiting for my luggage a few years ago…and I dug up the picture I took when this article prompted the memory.

Wolverines Seen Roaming About Mount Rainier National Park – What a boon remotely triggered cameras can be….and then DNA testing of hair to determine relationships!

 Meet the Squad of Mosquito-Eating Species – Birds, dragonflies, newts, aquatic turtles, and bats. We haven’t noticed very many mosquitoes around this year, but we try to replace the water in our bird baths frequently and make sure our gutters are draining properly. Having the birds around our house probably helps…and the turtles at the neighborhood pond do their part.

Unique Activities for Yesterday:

Going to the basement during a storm. Our phones went off with tornado warnings – which is rare in Maryland. We went to the basement. It turned out to be only heavy rain for us (not very windy either); to the east and south of where we live there was a lot of damage with trees/big branches falling and shingles flying.

Cleaning the leaves off the deck. Over the past week we’ve had several fronts come through that have blown leaves and branches onto our deck. They were still wet when I went out to clean up. I dumped the sediment that had accumulated in the bird bath too.

Finding Witches’ Butter. I photographed the fruiting bodies of Witches’ Butter on our deck railing. The deck is over 25 years old and even regular treatment can’t keep it clear for fungus; it is only visible during times when the wood is wet for several days.

I’m more concerned about a window frame that has the same fungus growing. I’m not keen about replacing the window but we might have to consider it.

Two Mile Beach Whelks

We also found whelk shells and egg cases at Two Mile Beach during our field trip during  Cape May Spring (birding) Festival . The shells are the largest on the beach and appear in a range of colors due to weathering.

There were also whelk egg cases. Our guide encouraged us to open them to find the small shells inside – whelks that were never grow to adulthood because their egg cases have become detached from their anchor in the sea and washed to the shore.

We took a picture with the cell phone and I dug out my macro lens clip for a closer look. They are miniatures of the adults!

2019 05 Daniel 6526.jpg

I didn’t bring anything to keep the sand and tiny shells…and there was not time to count the ones that were in the case. Supposedly each capsule can contain up to 100 eggs! From the picture – I think there were at least 30.

2018 Belmong BioBlitz – part 2

Continuing from yesterday….there was a web of very small spiders just off the path. They were all moving rapidly although it wasn’t clear where they going!

20180514_bioblitz spider web.jpg

Another benefit of the rain was the increased visibility of spider webs in the grass. Sometimes we could even see the spider hiding in the ‘funnel’ of the web.

These small white flowers were found down by the pond. They aren’t native – probably planted sometime during Belmont’s long history - but they are propagating themselves at this point.

20180515 bioblitz lichen.jpg

The lichen and moss seemed to have richer colors because of the dampness all three days of this year’s BioBlitz.

20180515 bioblitz snail.jpg

During one of the few times the sun came out (on the second day) – the group found a snail on blade of grass. Shortly after this picture was taken the snail’s weight bent the grass…a little drama in the meadow.

The group also documented a stand of locust trees – native but invasive; the stand was probably started by fill dirt that included the seeds.

When we started the last day, we thought it might start to rain at any time --- and were thrilled when we go about 1.5 hours of good observations – tadpoles, small insects, trees…and ropey roots under one of the big trees along the road. We headed back to the Carriage House at lunch time; it started to sprinkle as we got there.

The 2018 Belmont BioBlitz in a wrap!
