Gleanings of the Week Ending December 7, 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.

No need to overload your cranberry sauce with sugar this holiday season − a food scientist explains how to cook with fewer added sweeteners – Cranberries are one of my favorite seasonal foods. I like them so much that I buy enough to freeze and use well into spring – even summer. During the cold months I use them for relishes, adding to stir fry veggies, and in muffins. I’ll make the relishes more savory than sweet from now on!

Researchers Investigate Sustainable Ancient Construction Techniques – Studying the best-preserved earthen building in the Mediterranean. It was built between the eighth and sixth centuries BCE.

Floating Wetlands Bring Nature Back to Baltimore’s Inner Harbor – Built as part of the National Aquarium. The article interested me since we lived near Baltimore for so many years.

Check Out the Highest-Resolution Images Ever Captured of the Sun’s Entire Surface – Images from European Space Agency’s (ESA) Solar Orbiter.

Climate change and air pollution could risk 30 million lives annually by 2100 - Under the most probable projection, annual mortality rates linked to air pollution and extreme temperatures could reach 30 million/year by the end of the century. In 2000, around 1.6 million people died each year due to extreme temperatures, both cold and heat. By the end of the century, in the most probable scenario, this figure climbs to 10.8 million, roughly a seven-fold increase. For air pollution, annual deaths in 2000 were about 4.1 million. By the century's close, this number rises to 19.5 million, a five-fold increase. And yet – there is not the political will to change the scenario.

Vincent van Gogh’s Brilliant Blue ‘Irises’ Were Originally Purple – The paint faded since the painting was created in 1889. It’s still beautiful – either way.

Bee alert: Pesticides pose a real threat to over 70% of wild bees - Alarming risks that pesticides pose to ground-nesting bees (i.e. bumblebees, squash bees), which are crucial for pollination and food production.

The Chilling Sound of the Aztec Death Whistle - Creating 3D digital reconstructions of original Aztec death whistles…then recording sounds from originals and the reconstructions. Both produced sounds like a human voice or scream. There is a link to recording samples at the bottom of the post.

Overwhelmed by ever more clothing donations, charities are exporting the problem. Local governments must step up - There are more and more clothes in circulation, and they are getting cheaper and lower quality. That means the clothes you give away are worth less and less. Worldwide, we now dump 92 million tons of clothes and textiles a year, double the figure of 20 years earlier. Local governments usually handle other waste streams. But on clothes and textiles, they often leave it to charitable organizations and commercial resellers. This system is inherited from a time when used clothing was a more valuable resource, but the rising quantity of clothing has pushed this system towards collapse.

Oysters as large as cheese plates: How New Yorkers are reclaiming their harbor’s heritage – Perhaps the main accomplishment of the project, even more than increasing oyster population, is reminding New Yorkers that they are islanders. It's hard to care about something that is only abstract, something you don't have experience with. Ultimately, people have a much greater ability to improve water quality than the oysters ever will.

Lake Springfield Boathouse – May 2024

My husband and I enjoy the area near the Lake Springfield Boathouse for its meadow and birds. I forgot about our late May visit until I rediscovered the pictures I took!

The gardens around the boathouse were beginning to bloom and there were gardeners at work while we were there. There is a good stand of milkweed and butterfly weed but I didn’t see any Monarch butterflies.

The Purple Martin houses were full of birds!

Bluebirds were around as well. They are probably utilizing houses in the area, but I saw them near the feeders and nearby trees.

There were a pair of tree swallows on a sign as well. They use the same size house as bluebirds.

The meadow is beginning to bloom but the morning was still cool enough that I didn’t see many insects – a few butterflies and bubble bees.

My husband commented that he missed the meadow we frequented in Maryland that had a path mowed through it – the plants on both sides making it easier to get close to insects for photography. The meadow near the boathouse is one large area: no easy access to the interior.

Hagerman National Wildlife Refuge – June 2023

It was hotter and dustier than May on the afternoon I was at Hagerman…a stop on the road trip between my home and Carrollton TX. The riot of wildflowers of May has shifted toward thistles and sunflowers and lotus…with the May flowers producing seed.

There were three types of egrets I saw: cattle and snowy…

And then a great egret on a snag - scratching.

The black vultures were on the ground. They didn’t appear to be around feeding. They were just in a group at the edge of one of the ponds…socializing.

The butterfly garden near the visitor center has a wider variety of flowers still blooming.

And they were attracting butterflies. I watched one getting nectar from a cone flower.

There were several other kinds around too…and I saw one butterfly laying eggs on a plant that didn’t have any flowers (must have been the plant that the caterpillars like to eat). I had a pleasant conversation with a woman as we both enjoyed the garden; she was about my age, had bought a butterfly kit for a granddaughter (the caterpillar had successfully developed into a butterfly that was released), and was part of the rotation caring for her elderly father in his home…a wonderful chance encounter that made the road trip unique!

There were bees in the butterfly garden too. One was taking a break on a bench…an easy picture!

Zooming – November 2021

Three locations for my zoomed image collection this month: Maryland (home), Texas (Carrollton), Missouri (Springfield). Enjoy the slideshow of the whole group then look below for thumbnails by location!

Neighborhood Walk

It’s early fall in our neighborhood. There are a few leaves that are turning and falling. I found a pretty one at the base of our oak at the very beginning of my walk. The tree is struggling with the infection that is impacting (eventually killing) many oaks in our area and has already dropped about half its leaves. It will linger for a few more years. The one across the street has lost almost all its leaves already and I wonder if it will not survive the winter.

As I walked toward the storm water pond, I noticed another oak that was mostly green…except for one branch of yellow leaves.

The pond was too peaceful and quite – no frogs or red-winged blackbirds making morning songs, no turtles coming out to warm up in the sunshine. There was no algae or floating water plants and I wondered if the treatment used to control that ‘problem’ killed the other life in the pond. They are not mowed as far down the slope as they did at one time, but it seems like it would be better to let the vegetation grow a little further up the slope.

2021 10 IMG_9606 (8).jpg

There were plants going to seed…some with candelabra type branches supporting their fluffy seeds.

There were two types of goldenrod. Do you see the out-of-focus bee at the right side of the second picture? I didn’t notice it until I got home and looked at my images on a big screen….glad I captured the image since it shows the value of these late blooming plants to pollinators.

The willow has a tall branch that is dead – lower ones that are still green with slender branches gracefully sweeping the bank and hanging over the water. There are shelf fungus growing up and down the dead trunk.

2021 10 IMG_9606 (3).jpg

There are a few plants still blooming. One was down in the grass and the picture I took looks like it has an arching fuzzy boa spilling from the flower! In reality the fuzzy boa is an out-of-focus grass seed stalk.

2021 10 IMG_9606 (10).jpg

One of the houses has several Rose of Sharon buses planted on the pond side of their fence. I liked the extra wrinkles of the purple one (not completely unfurled).

The milkweed stand at the back of the pond was a disappointment. It was still there was overgrown with invasive pear seedlings that have grown rapidly over the summer. Maybe they will mow the area later in the fall to try to control that invasion for next season although the pear will come up from roots as well as the milkweed.

Overall – a worthwhile walk on a coolish weekend morning before many other people were out in the neighborhood.

Gleanings

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

Gleanings for this week

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.

Volunteers Spot New Sites in Aerial Images of England - Archaeology Magazine – Volunteers and lidar scans…a productive combination!

Seven highlights from 70 years of the National Science Foundation - The Bridge: Connecting Science and Policy - AGU Blogosphere – Deepwater Horizon oil spill, public radio and television, ozone hole, strong curricula for introductory science, deep-sea exploration, student opportunities, and COVID-10 response. It seems like the list it too skewed to recent years.

We don’t need nearly as much protein as we consume - BBC Future – Another recommendation of getting nutrients from food rather that highly processed food or supplements….and moderation too. Skewing the diet toward protein at the expense of other nutrients is not healthy!

The Coolest Kingfishers from Six Continents – I’ve seen the first three! All three in south Texas and the Belted Kingfish elsewhere too.  Kingfishers are an easily recognized shape….heavy bill, bigger head relative to body…etc.

How Americans are coping with COVID-19 stress -- ScienceDaily – This report was prior to the additional stressor of George Floyd’s death….the racism of police evident in the videos of the event and the response to protests that seems too militarized. It seems like 2020 will be a pivot point in our nation’s history and how we all respond to the stressors of the year is important in the outcome. I hope that we can show the best of ourselves…our utmost caring for all people and our planet that is our home.

Ice Arch Persists Despite Warm Arctic – It won’t last long…the ice arch which prevents sea ice from drifting south generally breaks up in June or July. Last year it broke up in mid-April.

'New' Footage of Benjamin, the Last Tasmanian Tiger Ever Seen Alive | Smart News | Smithsonian Magazine – A 21-second video from 1935.

Top 25 birds of the week: Seabirds - Wild Bird Revolution – I’ve seen most the North American birds in these photographs….except for the puffins.

Babies know when you imitate them -- and like it -- ScienceDaily – Most parents probably realize this to some extent…but the research teases out more specifics about how babies respond to knowing they are being imitated.

The remarkable power of the prickly pear - BBC Future – Grown as a crop for food in arid areas and then using the waste left after the food is extracted to generate biofuel. Wish we had more processes like this.

Unique activities for yesterday:

Aftermath of thunderstorm. I did another early morning in the outdoors – noting the aftermath of the thunderstorm the night before. Both birdbaths had been filled by the rain. The one in front is surrounded by day lily leaves…I’m not sure how often it is used by birds, but I like the way it looks from our front door.

2020 06 IMG_0077 (7).jpg

The sycamore tree trunk still looked very wet. I had forgotten the Virginia creeper climbing up. There were a few sycamore leaves that were blown into the yard…but the wind must not have been too bad.

2020 06 IMG_0077 (6).jpg

The wetness of the leaves kept some of the maple leaves flipped over. It’s always surprising that the underside is so light in color.

2020 06 IMG_0077 (8).jpg

Finally, I noticed a dead bee just before I settled into my chair. It must have gotten into the screened part of the deck and not been able to escape.

The rest of my outdoor time I spent making a couple of Zentangle tiles….and listening to the birds.

Mint as a fresh veggie. Mint grows so easily and comes back year after year. My front flower bed has a lot of it…enough to use it for more than a garnish. I cut a handful of stems and strip the leaves – it is the leafy green in a smoothie with chocolate protein powder. Yummy!

A Zentangle Prompt

Make a two tangle tile today with ROSCOE and SAND SWIRL.

Here is a tile I made yesterday based on the prompt: Three patterns to combine in a tile today: FAUX WEAVE, FEATHER FALL, and MEER.

Filling a Day of Social Distance – 3/30/2020

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

Here are the unique activities for yesterday:

Hearing traffic noise in the early morning. I woke up about an hour before my time to get up and heard traffic noise. We’re close enough to I95 that sometimes in the winter when the trees don’t baffle the sound and the weather conditions are right…we hear the trucks. I hadn’t heard it as much recently and thought it was the effect of the pandemic. Today it seemed more like a pre-coronavirus Monday. I dosed until my Fitbit vibrated at the usual time.

Discovered HiJinx podcasts from my local library. I listened to the most recent one - ‘A most notorious woman’ about a Grace O’Malley – Ireland’s Pirate Queen. (Anne Chambers’ book on O’Malley available at Internet Archive here.)

Seeing deer just after 8 in the morning….going back to the forest. I wonder where they spent the night. The forest behind our house is part of the green space along the river. Did the deer spend their night elsewhere or did they leave the forest for a morning browse on tender plants in the neighborhood (like my daylilies) for ‘breakfast’ and were returning to the forest because a car or two had come down our street.  

2020 03 IMG_8611.jpg

Later in the day – when it was warmer – I walked around the yard and noted that the daylilies were recovering from the deer browsing several weeks ago. They were not eating them this morning. Also, the daffodils are on their last legs. I took some macro shots of them.

More violets were blooming.

Dandelions are becoming more numerous too. I’m being lazy and leaving them alone. After the heavy rains a few years ago caused some of our lawn to turn to dirt with patches of grass I have come to appreciate the deeper roots of dandelions that hold the soil.

The leaves on the tulip poplar are a little bigger but the flower buds are not open yet.

o IMG_8625 (3).jpg

The cherry tree was attracting bees!

It was a wonderful sunny day and warm enough to have the windows open again. Hearing birdsong in the forest never gets old.

Remembering something I forgot to include in the post for last Friday – my husband had a telemedicine session. It was a first for us. It was a follow up after some tests and lab work from back in February….not coronavirus related. It was a lot less stressful than going into a doctor’s office during this time.

Receiving a communication from our Community Supported Agriculture farmer about what they have been doing to social distance while they work and the modified share pickup process planned when the season starts for us in June. I am reassured that they are thinking ahead…that I can still enjoy the bounty of fresh veggies this summer.

o IMG_8625 (8).jpg

Photographing the sunset. The sunset is not in my line of sight from my desk, but I can see it if I stand in front of the window and look to the left. I timed it right last night. The clouds reflected the orange light in an arc over the tall trees.

Gleanings of the Week Ending July 13, 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.

We organized a conference for 570 people without using plastic. Here’s how it went – It’s hard to do anything without plastic….but we’ll find ways eventually. I am focused on the ‘single use’ items first but when I can I choose materials other than plastic even for more durable items.

Arches National Park Recognized As "Dark Sky" Park – Now for my husband to find a way to get there with his telescope….

Timber Rattlesnakes: Cool Facts and an Uncertain Future – This snake is found in western Maryland….not in the county where I live. But we always mention it to students interested in snakes. This article provided some additional ‘cool facts’ to pass along.

Macro Photos of Water Droplets Reveal the Overlooked Beauty of Nature – Beautiful images in water droplets - And the artist included some pictures of the set up he uses to get the pictures!

In an Era of Extreme Weather, Concerns Grow Over Dam Safety – There have been dams in the news in recent years (like the Oroville Dam spillway failure in 2017). In our area, some small dams have been removed. But there are 91,000 dams in the US that are aging and need repairs. It’s going to be expensive…and the extreme weather we’ve been having probably makes it more urgent…but the funding is just not forthcoming so far.

Chiggers are the worst – Agreed.

Photo of the Week – July 5, 2019 – Milkweed in bloom. This is a blog post from The Prairie Ecologist…showing some bugs too. No Monarch butterflies though.

8 ways wild animals beat the heat – The mucous that hippos secrete was new to me…it’s acts as sunscreen, antibiotic, moisturizer, and water repellant. Now that we’ve learned that the sunscreen we’ve been using may be toxic to corals (and maybe to us too), perhaps we could develop an alternative by learning more about the hippo mucous.

Winter Bee Declines Greatest in 13 Years: Survey – Habitat loss, pesticides, Varroa mites….it adds up. Evidently in recent years the strategies that beekeepers have been using to deter mites have not worked as well. Some crops rely more on commercial beekeepers than others. Almonds, cherries, and blueberries are mentioned as examples.

Top 25 Wild Bird Photographs of the Week: Flowers – Last but not least this week…..birds and flowers. Enjoy the photographs.
