Milestones

Last week marked two ‘milestones’ in my Missouri Master Naturalist (MMN) volunteering:

My tree educational trunk capstone project (part of the MMN training) is finished (or at least at a good stopping place). I had intended to leave it at the Springfield Missouri Department of Conservation for storage…and I savored the fall foliage from my car when I got there. The fall has lingered this year without a hard frost to hurry the end. By the end of the morning, I was taking the trunk home along with some additional educational materials since there is a plan to use the trunk for outreach sessions in January and maybe the Osage orange would be dry enough to add to it by then. I’m still thinking about it as ‘finished.’

I also started a new project: creating a collection of soft pith stems in a bucket (suggestion from Wild Bee Lab Facebook Page). I’ll check it periodically to see if any bees use the stems for nests. My initial collection includes pokeweed, forsythia, bush honeysuckle, and goldenrod. Yes – some are non-native but if the bees use them, I’ll be even more vigorous in getting rid of the non-natives around my yard and doing this with the stems rather than burning them in my chiminea.

Project FeederWatch

My husband signed us up for Project FeederWatch and we are counting our feeder birds together – 2 days a week, an AM and PM time each day for a total of 2 hours. We have comfy chairs situated at a large window and leave our binoculars within reach. I do the logging into the app on my phone as we observe – no paper involved at all. This is the view from our window. I moved the chairs from around the table before our latest count. It’s a very calming activity. I usually have a cup of hot tea at my elbow.

We’ve had several rainy days. The light was poor enough that we opted to take the screens off the window (no bird strikes there so far). It made photography a little easier too.

A squirrel has come through may times while we’ve counted; it only stopped at a feeder once (didn’t manage to get anything) since there were plenty of acorns around and it’s the squirrel’s time of year to bury them!

The most numerous birds are sparrows (white throated and white crowned) and finches (gold and house). There are a couple of juncos but we had more last year so maybe they have not all arrived in our area yet from their breeding areas to the north. There are occasional titmice, chickadees, and a red-bellied woodpecker. The grackles are also occasional….they are too big to get much from our feeders; one or two come around to try but don’t stay long fortunately.

Our holly tree has berries, but we haven’t had any hard frosts yet…haven’t seen any birds eating the berries.

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.

Drought Expands Across the U.S. – We are finally getting some rain…but we are in the ‘extreme drought’ area of southwestern Missouri; it is going to take a lot to get back to ‘normal.’ On October 29, abnormal dryness and drought affected over 78 percent of the American population—the highest percentage in the U.S. Drought Monitor’s 25-year-long record.

Cholera, Zika and West Nile: The deadly diseases that sweep in after hurricanes – Damage to infrastructure has been the big focus of reporting in the US, but diseases are ramping up.

  • Florida health authorities released a warning in early October of a likely spike in Vibrio vulnificus infections, urging residents to avoid wading in floodwaters.  Vibrio vulnificus is a bacteria which can cause the breakdown of skin and soft tissue, sometimes leading to amputations.

  • West Nile cases rose in Louisiana and Mississippi following Hurricane Katrina.

  • Studies found that flooding in Louisiana following hurricanes Rita and Katrina led to an increase in the airborne fungi Penicillium and Aspergillus, which can cause allergies, respiratory infections and pneumonia.

  • Research into the aftermath of hurricanes Maria, Irma and Michael, shows that a significant number of people in Florida developed new chronic health conditions such as asthma and allergies in the six months following the disasters.

Satellite Imagery Shows Breadth of Flooding in Spain - Valencia saw a year’s worth of rainfall in just eight hours, with floods destroying buildings, disrupting trains, and leaving more than 100,000 homes without power.

What animal societies can teach us about aging - Humans are not the only animals to change our social behavior as we age. Red deer may become less sociable as they grow old to reduce the risk of picking up diseases, while older house sparrows seem to have fewer social interactions as their peers die off.

The world’s oldest tree? Genetic analysis traces evolution of iconic Pando forest - By sequencing hundreds of samples from the tree, researchers confirmed that Pando, a quaking aspen tree (Populus tremuloides) in Utah, is between 16,000 and 80,000 years old. Pando consists of some 47,000 stems that cover an area of 42.6 hectares in Utah’s Fishlake National Forest. Because of the way the plant reproduces, this collection of aspens is technically all one tree, supported by a single, vast root system. Pando is triploid, meaning that its cells contain three copies of each chromosome, rather than two. As a result, Pando cannot reproduce sexually and mix its DNA with that of other trees, and instead creates clones of itself.

Have we found all the major Maya cities? Not even close – Using lidar to survey 50 square miles revealed evidence of more than 6,500 pre-Hispanic structures, including a previously unknown large city complete with iconic stone pyramids.

Stunning Shortlisted Photos From the 2024 Close-Up Photographer of the Year Contest – My favorite was “Chicory” for the color…and that I knew what it was!

Low-level lead poisoning is still pervasive in the US and globally - Chronic, low-level lead poisoning is a major risk factor for cardiovascular disease in adults and cognitive deficits in children. Factors such as menopause and hyperthyroidism release lead sequestered in the skeleton, which causes a spike in blood lead concentrations. The solution to protecting people from lead poisoning is to identify and eliminate environmental sources of lead: eliminating lead acid batteries, replacing lead service lines, banning leaded aviation fuel, reducing lead in foods, abating lead paint in older housing, and further reducing lead-contaminated soil and other legacy sources.

Ghost Forests Creep Into North Carolina - Large swaths of cypress and pine forests along the southeast Atlantic coast have died, shed their bark, and become pale, leafless snags that line the waterways like gravestones. In the period before winds topple the snags over and shrubs cover them up, researchers call the eerie ecosystems “ghost forests.” One place that is it happening is Alligator River National Wildlife Refuge…and I realized I have been there! We visited in April of 2015. It was the first place I saw river otters and two vultures (different species) sharing a meal. There probably were bald cypress dying in 2015, but it is even more evident now.

Trees cool better than reflective roofs in vulnerable Houston neighborhoods - Heat islands occur in cities where structures such as buildings and roads absorb the sun's heat more than natural landscapes such as trees and grass. The researchers considered three different heat island mitigation strategies: painting roofs white to increase solar reflectance; planting vegetation on roofs to increase evaporation through the plants; and planting more trees, which increases evaporation and provides shade.

Wm. H. Edwards’ Butterflies of North America

As we head into winter – I am thinking about butterflies…how I didn’t see as many (or any species) this past summer. Maybe it is the drought in our area, and they will be more numerous next year. I hope so.

Edwards’ volume is the first of three he produced in the 1870s. The illustrations were done by Mary Peart and hand colored by Lydia Brown and often include more than simply the adult butterfly in the later volumes. They are well worth browsing.

The butterflies of North America

 I’ve not thoroughly browsed the other two volumes yet but I think I found them on Internet Archive as well: Volume 2, Volume 3.

Sustaining Elder Care – November 2024

I have two book/puzzle sorting days at my community library before I go off to Dallas again…I am hoping to find some more 300-piece puzzles to take for my Dad. I think he is probably running a bit low and maybe my sister is bringing some older ones back that he hasn’t done recently. We don’t have as many 300-piece as we do 500…and those 500-piece ones are getting too hard for him.

The past month has been more stressful in terms of elder care than I anticipated. There is a disagreement between us daughters about whether he is having pain when he eats and he needs his food ground up. Observations of him eating are not consistent. We have asked the dentist he saw last to make an assessment….since to make the change in mealtime routine for the assisted living staff will require a doctor’s order.  On the plus side – I don’t think my dad is aware of the turmoil. Most of the interaction among my sisters and I is via text; I’ve stopped looking at the messages about an hour before bedtime to try to reduce the impact on my sleep. It’s also caused me to start thinking more about what I want my relationship with my sisters to be separate from our shared interest in our father’s well-being.

McDaniel Park

The last field trip of the Identifying Woody Plants class was to McDaniel Park – a convenient commute from the campus. It had a lot of invasive plants (Japanese honeysuckle, Winter creeper, Bush honeysuckle, White Mulberries) but some native species too --- lots of good review. Unfortunately, I had forgotten my bridge camera so only had my phone for photography.

One of the review trees was Osage orange – Maclura pomifera – Moraceae. None of the trees had fruit under them. Had it been picked up or were they all male trees?

A new species was Rose of Sharon - Hibiscus syriacus – Malvaceae.  I was as fascinated by the insects on the seed pods (Hibiscus Scentless Plant bugs?)as I was the plant. This is a plant I am familiar with…not native but widely planted. The seeds are hairy!

The River birch - Betula nigra - Betulaceae is an easy one to id from the bark and catkins.

Did you know that poison ivy seeds are white? It was something I learned this semester…not sure why I had never noticed before.

Arcuately veined and opposite fall leaves of a silky dogwood – Cornus obliqua – Cornaceae.

And the variability of Sassafras leaves – Sassafras albidum – Lauraceae. For some reason, I got stuck years ago on ‘mitten’ leaves but the leaves are not always like that!

Our teacher collected seeds and twigs for the lab next week and that included Winged sumac – Rhus copallinum – Anacardiaceae.  I am intrigued that it is used to make tea. We previously saw smooth sumac but there were no seeds on those plants.

I couldn’t resist taking some pictures of fall foliage and a recently cut tree trunk (the tree was around 50 years old).

The field trip was a pleasant fall afternoon – a good finale. I am realizing I that  will miss the weekly classes and am solidifying my plan for the spring semester.

Gleanings of the Week Ending November 09, 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.

Old Growth – Mitch Epstein photographs of very old trees.

The true story of a famed librarian and the secret she guarded closely – Belle da Costa Greene, the first director of New York's historic Morgan Library and Museum.

Inside Turkey’s Mysterious Ancient City That Once Sheltered Thousands—Underground - The Derinkuyu underground city is a sort of gargantuan anthill, except made by and for humans—up to 20,000 of them at a time, in fact. The city descends 280 feet into the earth, divided into eight levels. Upper levels were primarily used for living and sleeping, while lower levels were used for storage, even housing a dungeon. The far-stretched system of interconnected rooms was carved out of the Cappadocia region’s tuff rock. People didn’t live in these underground quarters year-round, however, as they were mainly used for shelter during times of conflict or extreme weather.

Climate change will affect food production, but here are the things we can do to adapt - Farmers can pick crop varieties best suited to different climate condition...production can shift to places with more optimal temperatures…planting and harvest times can shift as the seasons shift…focusing on the right irrigation, fertilizer, pesticides synchronized to climate change. We have the chance to build a more productive and resilient food system, but it’s not guaranteed that we will. It depends on whether the seeds, irrigation, and adaptation practices will be available. That will require real and sustained investment from governments, donors, and private companies.

Toothbrushes and showerheads covered in viruses ‘unlike anything we’ve seen before’ - We live in a richly microbial world. Interactions with bacteria and other microbes in our homes are an integral part of our human biology.

The monarch butterfly may not be endangered, but its migration is - Migrating monarchs don't fly at night, so they spend their evenings in bunches on trees or shrubs, known as roosts. The study relied on 17 years of data from more than 2,600 citizen scientist observations of monarch roosts along the butterfly's migration route. The researchers found that roost sizes have declined by as much as 80%, with these losses increasing from north to south along the migration route. The evidence shows that when monarchs are reared in a captive environment, either indoors or outdoors, they're not as good at migrating.

World’s Rivers Are Driest They - In 2023, the hottest year on record, the Mississippi River and Amazon River basins were at all-time lows, while the Ganges, Brahmaputra, and Mekong rivers, which all have their headwaters in the Himalayas, were also unusually dry. Across nearly half the globe, rivers were drier than normal.

The worrying puzzle behind the rise in early-onset cancer - Over the past 10 years, rates of colorectal cancer among 25- to 49-year-olds have increased in 24 different countries, including the UK, US, France, Australia, Canada, Norway and Argentina. Perhaps the most obvious explanation points to the role of obesity and metabolic syndrome, conditions which have been associated with driving cancer risk through increasing inflammation throughout the body and causing the dysregulation of key hormonal pathways. Or maybe changes in sleep patterns is part of the explanation. Combined with shifts in lifestyle, many cancer scientists believe that a key driving force for these illnesses is the consequences of various toxic changes within the gut (from microplastics). Antibiotics might be involved too. The bottom line…it’s a looming public health crisis.

New research reveals how large-scale adoption of electric vehicles can improve air quality and human health - Computer simulations show that aggressive electrification of the U.S. vehicle fleet, coupled with an ambitious rollout of renewable electricity generation, could result in health benefits worth between US$84 billion and 188 billion by 2050. Even scenarios with less aggressive grid decarbonization mostly predicted health benefits running into the tens of billions of dollars.

New study explores how universities can improve student well-being - Six guiding principles for improving student well-being:

  • Embedding well-being into curricula for broader, more accessible adoption.

  • Having each initiative only focus on one or two aspects of well-being, making it easier to create instruction that can also be more immersive.

  • Tailoring initiatives to the student body and university culture.

  • Securing buy-in from faculty.

  • Ensuring new offerings are accessible and don't create additional financial burden for students.

  • Employing an iterative assessment framework at the beginning to make it easier to change or scale up a program.

A Hand-book to the Order Lepidoptera

William Forsell Kirby was an English Entomologist that authored a 5-volume Handbook to the Order Lepidoptera in 1896 and 1897. I am featuring the 1st volume as this week’s ‘book of the week’ because I was so pleased to find it. I had somehow browsed the other 4 volumes back in 2016! Enjoy the 4 sample images….and follow the link to see many more.

A hand-book to the order Lepidoptera - volume 1

The links to the other 4 volumes are: two, three, four, five.

Valley Water Mill Park

The MSU Identifying Woody Plants class went to Valley Water Mill Park last week. It is northeast of Springfield MO and includes a variety of habitats: upland forest, bottomland forest, wetland, glade, prairie, savanna, and lake/stream. It’s a place I will want to visit again.

We saw a lot of trees we had seen before and some new ones too. The fall is changing the way we go about identifying the woody plants we’d seen before.

The bald cypresses are losing their needles…and there were trees at this park with knees (the previous ones were growing in locations where they did not produce knees). The knees make them easy to ID.

The buttonbush had lost its leaves, but the round seed heads make it easy enough to ID.

There were lots of sycamore leaves on the ground…many were huge and, sometimes, still green.

A Wahoo was obvious but our teacher said there was aphid damage too which is frustrating.

Poison ivy berries…new-to-me…good to know.

Black cherry bark – of a young tree and an older tree.

Some new species:

A bittersweet – no leaves but lots of fruit.

A chestnut – ID from the bur alone down to genus.

Japanese honeysuckle. This is one I recognize easily but I hadn’t noticed the seeds before.

Coralberry. This might be one I add to my yard someday – although I don’t know where yet.

Black haw or cherry-leafed viburnum is even more likely to find its way into my yard. It might make a good planting in the bowl left from a tree in my front yard that was removed before we bought the house.  It is a shrub that does well in shade so it might work to fill in between the two maples and provide flowers in the spring and fall/winter food for wildlife.

The lake was low even though there had been about an inch of rain the previous night. The area has been in drought for so long that it is going to take time to replenish the water level. There was evidence of beaver (many of the trees have wire cages around their base for protection.

Valley Water Mill Park might become one of my favorite places in the Springfield area.  My husband and I will probably make a ‘field trip’ there and walk the whole loop around the lake. I also filled out the form to volunteer for their education/outreach programs.

Garrison Springs Community Forest

There were still some leaves on the trees when we visited Garrison Springs Community Forest in Ozark, Missouri last month. It is a newly opened natural area snuggled into the developed area of Ozark. The vegetation makes it feel much further out; the ‘noise’ of the place is only the gurgle of water from 3 springs and the sounds of birds singing and leaves moving in the breeze.

Our area had gotten very little rain the past few months, but the springs still were flowing, and robins were bathing along with the newly fallen leaves.

A daddy long legs (harvestman) crossed our path as we headed back to the car. We stopped to get a picture.

This place is small but not that far from where we live…a place to visit again for a quick nature fix…and to see the improvements as they happen in the next few years.

Missouri Master Naturalist Training – Week 9

The last session of the Missouri Master Naturalist Training was one lecture followed by graduation and ice cream cake!

The lecture was on invasives. Most of the invasive plants I was familiar with (from Maryland)…except for Sericea Lespedeza which is a warm-season, perennial legume. It is something that was introduced intentionally then escaped and is now widespread – outcompeting native plants. Frustratingly – its seeds are still being sold and attempts to stop that at the state level have failed.

There were some trunk sections of young ash trees killed by Emerald Ash Borer. The widespread death of ashes in Missouri is happening now…just as it did in Maryland several years ago.

The good (so far) news on the invasive insect front is that Missouri does not have Spotted Lanternfly…although it is probably only a matter of time since the insect is in Illinois and Kentucky.

Graduation included a magnetic name badge and a certificate (and some goodies that included milkweed seeds). I splurged and had 2 pieces of ice cream cake!

I am going to miss the rigor of the class but am relaxing a bit – savoring my Identifying Woody Plants class at the university that continues into December!

Astonishing Photo of Millions of Monarch Butterflies Wins 2024 European Wildlife Photographer of the Year Contest – Starting out the gleanings list this week with beautiful images from nature.

Iceberg A-68: The story of how a mega-berg transformed the ocean - Scientists following A-68's birth and demise were able to track just what such giant icebergs do to the surrounding ocean. For its short, transient life as an iceberg, A-68 became a frozen lifeboat for a wide range of species. Over its three-and-a-half-year journey since it broke away from the Antarctic ice shelf, A-68 lost 802 billion tons of ice as it thinned from an average thickness of 770ft (235m) to 551ft (168m). Over a three-month period at the end of 2020 and start of 2021, it dumped an estimated 152 billion tons of fresh water into the ocean – that is equivalent to almost 61 million Olympic-sized swimming pools. At the peak of its breakup, around 1.5 billion tons of fresh water was gushing into the ocean every day. The crushing weight of the freshwater from A-68a as it melted may have helped force carbon-based material down more quickly, to depths where it was less likely to be eaten.

Salmon Make a Long-Awaited Return to the Klamath River for the First Time in 112 Years, After Largest Dam Removal in U.S. – Four dams blocked the salmon’s migration between the Klamath basin and the Pacific Ocean…but now the dams have been removed, and the fish are returning. The first salmon in the river since 1912 were spotted less than two months after the last dam was removed.

Avian architects: weaver birds in Africa have unique building styles – The African white-browed sparrow weavers build nests that look like pompoms in acacia trees. Some families build roosts that are very long, with long entrance and exit tubes; others will build roosts that are much shorter, with hardly any tubes. Essentially, it looks like different white-browed sparrow weaver families have different architectural styles. Researchers excluded all environmental and genetic explanations for the differences in the structures built by different families. Maybe, like humans, some species of birds have their own architectural traditions passed on across generations through social interactions.

Huge! A Roman Engineering Marvel Reaching Across a Spanish City - In Segovia, the Romans built an aqueduct that stands as arguably their greatest architectural legacy from six centuries in Spain. After drawing water from the Frio River, the aqueduct runs underground for some 10 miles before appearing in Segovia as a grand, elegant beast that strides for nearly 2,400-feet across the town. Comprised of more than 20,000 blocks of granite and erected without a lick of mortar, at its highest point the aqueduct reaches more than 90-feet high with narrow, double arches. It remained in use until the late 1970s.

Life-saving spongelike 'bandage' rapidly stops hemorrhaging and mitigates risk of infection - A liquid gel comprised of siloxanes (silicon and oxygen) that is delivered via a special two-chamber syringe which rapidly expands into a spongy foam upon exposure to each other within the wound in under one minute. The sponge applies pressure to restrict the hemorrhage at the delivery site while also serving as an antibacterial agent because of the silver oxide in it.

Learning in the Environment: The Importance of Expanding Outdoor Education Across the United States - Although environmental discussions are expanding in schools, students often lack the opportunity to interact with the natural world through outdoor education, including place-based learning located in nature. The widespread decline of green spaces, especially in densely populated areas, restricts youth engagement with the environment. Interacting with the outdoors helps students to understand not only the environment itself but the role they can play in protecting it.

Chickpeas: Sustainable and climate-friendly foods of the future - Chickpeas are a drought-resistant legume plant with a high protein content that can complement grain cultivation systems even in urban areas. I have discovered that roasted chickpeas is my favorite ‘crunch’ topping for soups and salads!

Photo Contest Celebrates Excellence in Architectural Photography – I haven’t done much architectural photography…but maybe it is something to consider…when I am not able to do nature photography (which is my favorite).

Grasslands live in the climate change fast lane - The rapid shifts in grassland communities involve not only the gain of some hotter, drier species but also the loss of some cooler, wetter species. These shifts might have negative consequences such as dominance by non-native species and loss of biodiversity.

Ten Little Celebrations – October 2024

The temperatures were more pleasant in October….I enjoyed the outdoor field trips and classes a lot more.

Pleasant temperature to walk around the Missouri campus during class. We were outdoors longer but it was easy compared to short hikes around campus in August and September!

Field trip to a healthy stream and woodland. Celebrating the water quality and the native species (not overcome by invasives)!

Cut down a Japanese barberry and burned most of it. Celebrated one more non-native (that is sometimes invasive) being gone from my yard.

Geology field trip plans. I celebrated that enough of my Missouri Master Naturalist classmates and chapter are interested in geology field trips to make them a likely late fall/early winter activity.

Getting seeds planted. I got buckeye, Hopi sunflower, common milkweed, and persimmon seeds during the second week of October….and celebrated when I got them planted. Some must go through the cold temps of winter to sprout in the spring.

Volunteering at a fair for homeschoolers…talking about Monarch butterflies. I celebrated by first gig as a Missouri Master Naturalist…and that my iPad-based slideshow of Monarch butterfly pictures was well received.

Owl Pellet. I vaguely remember that I had dissected an owl pellet in some previous training…but I celebrated that I did a more thorough job this time… and found a complete rodent skull…and the backbone…lots of ribs.

First solo Missouri Master Naturalist volunteer gig. I celebrated that the two days spent doing an after-school program with a local school for gift students was positive for them…and for me!

Whataburger. Sometimes I just want to splurge. On the way back from my Dallas trip, I stopped for a Whataburger…celebrated that it tasted just as I remembered - although I won’t do it very often.

Successfully completed my Missouri Master Naturalist training. Hurray! I am celebrating what I learned and that I now have more time to volunteer!

Missouri Master Naturalist Training – Week 8

Week 7 of Missouri Master Naturalist consisted of two sessions: a lecture on Fungi that was part of the monthly chapter meeting and two lectures in our regular class: Snakes of Missouri and Endangered Species and Conservation. I took notes during all three! I particularly enjoyed the photographs in the fungi lecture, the snake experiences from a place we had visited for a field trip, and the example used for talking about endangered species (freshwater mussels). I still have a lot of materials from the Missouri Department of Conservation that were on the handout table to browse through from the regular class: salamanders, snakes, mushrooms, lizards, crayfish, toads and frogs, caves and karst, Missouri fishes.

During week 8, I also took action to learn more about Missouri geology on my own since it is not a topic that was covered in the training….starting with two books: Roadside Geology of Missouri by Charles G. Spencer and Geology of Missouri State Parks by Max W. Reams and Carol A. Reams. The second book is the most current – copyrighted in 2022; about 25% of the books is an overview of Missouri geology and then there are sections for state parks by physiographic region. I’ll start with the state parks since it seems safer than stopping at road cuts…although I might keep the Roadside Geology in the car for when my husband is driving, and I can observe as we are on the road.

Next week is graduation week! The time has flown by. I have an evaluation form that I am completing this weekend.

Gleanings of the Week Ending October 26, 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.

A new era of treating neurological diseases at the blood-brain-immune interface – Investigating the connection of neurological diseases and a toxic immune reaction caused by blood that leaks into the brain….in particular, how fibrid (a blood protein) is responsible for setting of this detrimental cascade.

Antifungal resistance is not getting nearly as much attention as antibiotic resistance – yet the risks to global health are just as serious – Just as with antibiotics for farm animals, tons of fungicides are used annually to protect crops, of which some work the same way as antifungals used in humans. And just as bacterial resistance develops…fungi develop resistance too. Combating drug-resistant fungal infections is a complex problem. An important factor is that diagnoses of infections are often delayed – if they are even diagnosed at all. Simple tests for fungal infections are rarely available.

Nikon Small World Contest Celebrates 50 Years of Photographic Excellence Under the Microscope – Great images….the natural world that we can see only with assistance…an art form too.

So Last Season: The Environmental Impact of Fast Fashion and Textile Waste Exports - The last ten years have seen a dramatic increase in the production of single-wear garments—which has contributed to an excess of textile waste and consequent health impacts for the individuals who work in the textile manufacturing industry. Every aspect of the creation of fast fashion garments is unsustainable, from the creation of plastic-derived textiles to the construction of pieces by underpaid and overworked exploited laborers. Up to half of American textile waste is shipped to nations overseas. Adopting more sustainable wardrobe practices not only helps us move away from fast fashion, but also significantly lowers our individual carbon footprints and waste production.

Plastic pollution harms - Nano- and microplastic particles (NMP) are increasingly polluting urban and rural landscapes, where bees and other beneficial insects encounter them… it can damage their organs and cause changes in their behavior, preventing them from properly performing ecosystem services such as pollination and pest control.

British Ecological Society Photo Contest Celebrates the Breadth and Beauty of the World’s Biodiversity – I liked the variety of selections in this photo contest.

Introducing Six Steps to Calm: Our science-backed, stress-busting email course – From BBC…I subscribed…plan to take the course!

Your diet can change your immune system — here’s how - There is still much more work to do to unpick the effects of specific diets on the immune systems of those with different health conditions. However, a growing group of immunologists are optimistic that the mechanistic insights they are uncovering are the first steps towards personalized diets for a range of medical conditions.

US air pollution monitoring network has gaps in coverage - Most of the harmful effects from outdoor air pollution in the U.S. are linked to inhalation of fine particulate matter (PM). These suspended particles, like soot or liquid aerosol droplets, are smaller than 2.5 micrometers in diameter, garnering the designation PM2.5. In February 2024, to better protect Americans from health burdens caused by inhaling particles, the EPA adopted a more stringent standard for PM2.5. The EPA tracks compliance with air pollution standards through a network of about 1,000 costly and highly accurate monitoring stations placed in cities and towns nationwide. People of color and people with low socioeconomic status living in the U.S have fewer monitoring stations than other areas to measure air pollutants, meaning they may not be fully protected by the tighter air pollution standards.

Researchers Parse the Future of Plankton in an Ever-Warmer World - Climate change is hitting our oceans hard, making them warmer and more acidic, while radically altering currents. The outlook for plankton is mixed. As the planet warms, the diversity of the menagerie in many spots is increasing. But certain species are losing out, including big juicy plankton thought to be important for food webs and carbon sequestration. And, in the long term, plankton numbers may plummet as climate change starves them of nutrients. Meanwhile research continues: which plankton species are where but also exactly when, since shifts in bloom timing can also have big knock-on effects for fisheries. And the viruses that attack plankton seem to be on the rise as waters warm — another factor with as-yet unknown consequences.

Life Histories of North American Birds

The 6 early volumes of Arthur Cleveland Bent’s 23 volume work, Life Histories of North American Birds are available on Internet Archive. The work was published from 1919-1968…the later volumes completed posthumously after his death in 1954. The volumes available are from before 1930.

Bent evidently traveled extensively and interacted with 100s of people to compile the histories…quite an undertaking – more so since it was done before the computers! He started the work when he was 44 years old and spent the 44 remaining years of his life working on it. The work includes numerous photographs; I provide two from each book below but there are many more – well worth browsing these volumes - and the text is interesting as well.

Missouri Master Naturalist Training – Week 7

The 7th week of Missouri Master Naturalist (MMN) training included one evening class and my first solo volunteer gig.

The class lectures were on

  • Forest Ecology and Management

  • Pondering the Pond as a Wildlife Habitat

Forest Ecology and Management was done by a Missouri Department of Conservation Educator; I would like to have the charts since he went through them very quickly! The last segment of the lecture was hands-on…passing out small branches from the tree to everyone and then using the dichotomous key in the back of the Fifty Common Trees of Missouri booklet to id it….a red maple. I photographed my branch’s buds, branches and leaf imperfections!

Pondering the Pond as a Wildlife Habitat was done by a person that has been a MMN for over a decade…and done a lot of videography at a pond in a hayfield (i.e. not used by cattle…with adequate vegetation around its edge). Her Youtube Channel – Nature in Motion is something I will be viewing over the next month! She showed over 100 species in 17 minutes of her talk…fast paced…prompted me to think later about the richness in the intersection of science and art.

The volunteer experience was an after-school event at a local school for gifted students…15-20 minutes sessions with two groups of about 12 students each…on two days. My theme was getting outdoors in the fall and looking at some things that could be found.

My table was set up with items to look at: pinecones (3 different kinds), acorns (3 different kinds), Osage orange fruit, black walnuts (in a bag complete with emerging caterpillars), goldenrod (in flower and seeds), magnolia pod, maple branches, and a holly branch.

It also included a hands-on experience with pressed leaves/small branches. Each student made observations about their leaf (color on both sides, holes, insect eggs, shape)…and then compared it to other leaves at their table. The leaves were mostly oak or maple although there were some that were unique (river birch, magnolia, oak leaf hydrangea, boxwood).

The time past very quickly!

Gleanings of the Week Ending October 19, 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.

Antarctic 'greening' at dramatic rate - Vegetation cover across the Antarctic Peninsula has increased more than tenfold over the last four decades… fundamental changes to the biology and landscape of this iconic and vulnerable region.

Is cleaning with baking soda better for the environment? – Maybe not…and it might not be very good at some types of cleaning either.

Meet Milagra, a Rare Condor Rescued as an Egg and Newly Released Back into the Wild – A success at Arizona’s Vermilion Cliffs National Monument.

Landslides, Thousands Of Downed Trees, Undercut Roads Along Blue Ridge Parkway – Lots of repairs for the National Park Service after Hurricane Helene. Some damage is severe enough (i.e. more than just clearing mudslides and debris) that it will take time to repair. The fall foliage will come and go.

In Search of Microbes That Weave Colors into Moroccan Carpets - A scientist’s quest for microbes that produce purple pigments led to the vibrant world of natural dyes for women in the Atlas Mountain region of Morocco creating sought after traditional woven carpets…it’s a great intersection of biology and traditional artistry! The findings are compiled into a 48-page open-source guidebook, also translated into English, which described their project, introduced microbial dyeing, and catalogued recipes for plant dyes.

Dementia diagnostic markers change with time of day - Biomarker levels (p-tau217) were at their lowest in the morning when participants woke and highest in the evening.

Great Lakes Water Quality Project Seeks to Restore Coastal Vegetation - Returning certain croplands to perennial vegetation to reduce runoff and limit erosion.

'A warmer, sicker world': Mosquitoes carrying deadly diseases are on an unstoppable march across the US - West Nile virus, Eastern equine encephalitis (EEE), malaria and dengue…The mosquitoes that carry these diseases are thriving in a warming world.

Extinct Volcanoes Could Be Source of Key Metals Needed for Clean Tech - Rare-earths lurking under extinct volcanoes may be easier to extract. The iron-rich magma that formed some extinct volcanoes would be up to 100 times more efficient at concentrating rare-earths than the magma found in active volcanoes today. By one estimate, demand for rare-earths is set to grow fivefold by the end of this decade so finding them closer to home could contribute to more rapid conversion to clean technologies.

See Newly Discovered Nazca Drawings That Depict Llamas, Human Sacrifices and More - With the help of artificial intelligence, researchers have found hundreds of ancient artworks carved into the pebbled ground of Peru’s Nazca Desert in 6 months compared to 430 found between 1927 up to before the use of AI.

Missouri Master Naturalist Field Trip (2)

Continuing the blog about the Missouri Master Naturalist (MMN) field trip taken last weekend…

My second rotation was nature journalling. I made a Mindmap on the page of my journal during the intro – and decided to do some leave rubbings first. I had brought a stool for the session (a lesson learned from last time when I stood the whole time…and wore myself out). I quickly discovered that the journal book did not have a hard enough cover to support rubbings. I managed to use my phone to provide a more sold surface for the notebook and did 4 rubbings. I found some leaves with galls and other spots…decided to so some macro photography with my phone. I couldn’t resist documenting what the inside of a spicebush seed looked like.

I walked around taking a few pictures of the surroundings…remembering to look up! All the while I was making notes in the journal about what I was thinking as I took pictures.

Then I noticed a shed with moss and leaves on the top. I took some pictures of it…remembering the concept of intimate landscapes from a book read years ago and decided to so some of that kind of photography.

The black walnuts in various forms of blackness were an obvious subject. I took several different black walnut ‘landscapes.’ The one I liked the most was an empty husk in the moss with a violet and some brown leaves….did a squirrel take the nut? The second favorite was a group of plants that formed an arch…with red fruits. It looked like a good start for a fairy house.

The last rotation was at the stream to look for macro invertebrates. It was my first time in my river boots since we moved to Missouri…they didn’t leak but I need to practice walking in them!

The water was very low and that made it harder to effectively use the seines although we did find a lot of water pennies. The other group found a couple of small hellgrammites…but the big find was right at the end: a dragonfly larva that looked like a leaf! What a great finale for our field trip activities.

Missouri Master Naturalist Training – Week 6

Week 6 of Missouri Master Naturalist (MMN) training was busy because I also did my first MMN volunteering too! I’m counting that ‘first’ as part of the training. The evening class was focused on:

  • plants and their pollinators. This was a great update --- particularly about native pollinators. I’d learned some things from my etymologist son-in-law (i.e. I had seen the video of buzz pollination and had observed nectar robbing behavior when touring a garden) but it was observational rather than an organized lecture. This lecture filled in the holes of what I had learned previously!

  • the educational trunk contents and the kinds of programs we do with them. There are bins (“trunks”) for bison, pelts, skulls, insects, birds, turtles, amphibians…and they are trying to develop a new one about urban pollinator landscaping. I got more ideas for the tree educational trunk I am creating…understanding more about how it will be used. I am not sure how often I will use some of the trunks, but it is good to know that they exist.

My volunteering at the MMN table at a fair of home schoolers was the highlight of my week. The 4-hour fair was held at a local nature center and organizations had tables of activities for the 300 families that had registered for the event. The MMN table was focused on Monarch Butterflies. We had life cycle puzzles for the students to work, 2 chrysalis in a mesh tent (one healthy, another parasitized), seeds for 3 kinds of milkweed, a coloring page, and a vocabulary word/definition matching page, lots of brochures, and a slideshow (I had put together the slideshow from some recent photographs I’d taken to play on my iPad…the charge lasted for 3.5 hours). By the end we had no seeds left and very few brochures. It was a well-attended event!
