Missouri Master Naturalist Training – Week 5

There were 2 training evenings and a Saturday field trip in week 5 of my Missouri Master Naturalist Training.

The first evening was about Lions (mountain lions), Tigers (tiger swallowtail butterflies), and bears (black bears) native to Missouri. The tigers and bears have established populations in the state whereas the lions are wandering males from other states (so far). The bears segment included a pelt, skull…and some videos of black bears enjoying a good back scratch (using a tree trunk) and a slides about how the research on the Missouri bear population is done/what has been learned. The largest concentration of black bears in Missouri is close to Springfield!

The second evening was about prairies, which was a good follow up to our field trip to La Petite Gemme a few weeks ago, and animal skulls. The animal skulls session was probably the one with the most new-to-me content; there as a collection of skulls that we were told to organize in a continuum from herbivore to omnivore to carnivore…what a great hands on experience. The most unusual skull was the one from the armadillo!

The field trip was to the Springfield Botanical Gardens. It was in two segments:

• Focusing on the Roston Native Butterfly House and Caterpillar Buffet garden next to it…with the butterfly garden nearby where there were quite a few migrating Monarch butterflies (one of them that we watched being tagged).

• Then a general walk around the garden with some commentary on the features of the garden, the challenge of vandalism, and lots of evidence of fall. I picked up a few leaves and a black walnut to add to my tree educational trunk. The sky was clear…so an excellent day for looking up at trees!

The day also included a presentation about the value of dark sky (also learning that St. Louis’ Stacy Park is an Urban Dark Sky Place) and dissection of a Barn Owl pellet. I found a complete mouse skull and backbone in my pellet (and pieces of an insect’s exoskeleton) along with a lot of smaller bones; I was one of the last students to leave because I was finding so many bones in my pellet!

Gleanings of the Week Ending November 26, 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.

Battle Over Bears Ears Continues in Utah – I am looking forward to visiting Bears Ears and Grand Staircase-Escalante National Monuments and hope that their boundaries stay the way the tribes that have used the area for a very long time want. At some point Utah and the counties that are opposing the size will recognize the values of the tribes and country that want to preserve historical, paleontological, and geologic aspects of these places….and that the state benefits significantly from people visiting. The tourism $ may become more dependable and long term than other uses of the land.

Pyramid and Hundreds of New Kingdom Coffins Found in Egypt - An Old Kingdom pyramid, 300 New Kingdom coffins with well-preserved mummies with names of the deceased, and nearby a pyramid to Queen Neith…a previously unknown Queen.

Long-COVID clinics are wrestling with how to treat their patients – Frustrating situation.

Fenced In: How the Global Rise of Border Walls Is Stifling Wildlife – Border walls have increased since the end of the Cold War! This makes climate change an even bigger challenge to mammals…because they cannot move to better habitat if there is a border wall in the way.

Baby's vaccine responses linked to birth delivery method, study finds – Babies born via Caesarian section have lower antibody levels after vaccinations than babies born naturally.

Scientists Discover More Than 22,000 Endangered Manta Rays off Coast of Ecuador – Larger than any other Manta Ray population.

A Massive Freshwater River Is Flowing Under Antarctica’s Ice – It is flowing at 3 times the rate of the Thames. This finding helps understand some problems with existing models…hopefully it will allow for model updates to predict the impact of warming more accurately on Antarctica’s ice.

A Field Guide to Jackrabbits – Hard to see denizens of the western US (and Mexico).

France Looks to Mandate Solar Panels Over Large Parking Lots – Good idea…maybe it will begin to happen in the US even without a mandate.

Bright LEDs could spell the end of dark skies – Hope cities can learn to use LEDs like Tucson…not overuse bright white LEDs.

Gleanings of the Week Ending February 12, 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.

Why the Dutch embrace floating homes – Maybe other coastal areas around the world should be looking at this kind of development…or mitigation strategy. Otherwise - there is going to be a lot of migration away from coasts that will become more and more prone to flooding in the decades to come.

New Antarctic Penguin Colonies Discovered Further South than Normal – Good news for the Gentoo penguins - there is more space on Antarctica now; previously the areas were too icy for these birds. On the downside – there is less area suitable for penguin species that previously lived there and there might be less food available for them all as warming continues.

Three people with spinal-cord injuries regained control of their leg muscles – There has been a lot of research in this area over the past decade; perhaps we are coming to a point where rapid advances are going to be made.

Why to flickers knock on your house? – Not just why they knock but other interesting behavior…made me consider putting up a flicker box to give them a place to raise young.

Dog feces and urine could be harming nature reserves – A study providing rationale for requiring dogs on leashes and owners removing their dog’s feces in natural areas.

Top 25 birds of the week: February 2022 – My favorite this week is the Great White Pelican. Somehow pictures of birds from the front like this always give them a rather assertive appearance.

US household air conditioning use could exceed electric capacity in next decade due to climate change – Not good. Implementation of mitigation strategies need to ramp up quickly. As an individual homeowner, I am thinking: 1) increase efficiency (heat pump or geothermal, more insulation, solar screens on any window getting full sun sometime during the day, maybe upgrade windows/doors) and 2) solar panels on the roof with storage battery.

Threats from QAnon conspiracists force butterfly sanctuary to close – Sad. My husband and I visited the butterfly sanctuary on a rainy day during the Rio Grande Birding Festival in 2017; it wasn’t a good day for butterflies, but we always thought we’d come back on a warmer/sunnier day during some future visit to the area --- then the border wall and the conspiracists has ended it all.

More spice could help seniors avoid salt – Yes! Lemon pepper (the kind without salt in it) is one of my favorites…and any of the components that come under the heading of ‘Italian seasoning.’ I dry my own orange peel (any time I eat an organic orange…the peel gets processed and dried). It helps to use fresh ingredients too (i.e. avoid no-salt version from cans…they have never tasted good to me no matter how they are prepared).

Star Bright: What are Dark Sky Reserves? – Staunton River  (where we’ve been for ‘star parties’) is a Certified IDA International Dark Sky Park….maybe we’ll visit one of the Reserves post-pandemic. Right now – the closest one to us is the one in Canada (just north of Vermont/Maine).

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.

Night Sky Celebrations Across the National Park System – We’re not doing this kind of traveling this summer….but maybe we’ll do several of these ‘star parties’ in summer 2022.

Tooth loss associated with increased cognitive impairment – Another reason to not neglect going to the dentist! It’s not just about preserving cognitive impairment either….quality of life is a big motivation as well.

Top 25 birds of the week: Seabirds – From around the world…a few I’ve seen in North America.

Mucus and mucins may become the medicine of the future – There is still a lot to learn about how this might work….but it appears that this is an opportunity to treat disease by enhancing the mechanisms already used by the body. Maybe one of the first uses will be for eye drops to treat eye infections rather than the antibiotics used today.

Protect Pollinators – reform pesticide regulations – Hopefully the action requested by these scientist from around the world will happen…our ecosystems are having enough challenge dealing with climate change. Many pollinator species won’t survive the continued threat of status quo pesticide use.

Keeping your composure: Creative Ways to Compose Your Photographs (part 1, part 2, part 3) – Always good to browse through these kinds of tutorials…pick up some new ideas, celebrate the things you are already doing.

What to do with food waste? – It doesn’t appear than there is any one strategy that will work broadly. I’m glad I have already dramatically reduced food waste and then have a large enough yard to have a compost bin.

Waterfalls of North Carolina – A few years ago, my husband and I made a waterfall themed trip to New York. It seems that North Carolina would be another state that has a lot of opportunities for waterfall photography. Maybe next spring?

Creativity Myths – A recent ‘letter’ on The Painter’s Keys website.  I enjoy the twice-weekly blurbs that appear in my inbox (free subscription) and often follow the ‘click here to read more’ link.

Exposure to light with less blue before sleep is better for energy metabolism – I already change the color balance on my PC screens to ‘nightlight’ between sundown and sunrise. Maybe we will do more eventually based on this and subsequent research. It is probably true that no one should be watching a television screen just before going to bed!

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.

Human egg cells are imperfect surprisingly often -- ScienceDaily – More than 7% of human oocytes contain at least one exchangeless chromosome pair…and the frequency is not affected by maternal age. Our species is hardwired to have significant numbers of miscarriages and babies with extra or missing chromosomes. The finding is interesting, but I immediately thought of some questions…has this changed over the past 100 years (i.e. have we changed our environment enough that we are impacting our reproductive success) and how does this frequency compare to other mammals?

Why our pursuit of happiness may be flawed - BBC Future – A thought provoking piece about how seeking ‘happiness’ often sets the stage for disappointment…rather than contentment.

Pollution from cooking remains in atmosphere for longer -- ScienceDaily – Eating deep-fat fried foods is not just unhealthy…the cooking of foods that way contributes to air pollution. In London, 10% of the PM2.5 particles are from deep fat frying….in Hong Kong 39%!

2nd Annual Threatened And Endangered Parks: Natural Darkness And Sounds – My husband and I are looking forward to more dark sky opportunities in national parks. So far – the ‘star parties’ we’ve been to have been at state parks and hosted by amateur astronomy clubs in the area. The dark sky venue requires a bit of infrastructure to support a field full of camping amateur astronomers with their telescopes (electricity for telescopes/computers and bath rooms with red tented windows).

Top 25 birds of the week: Colouration! - Wild Bird Revolution – Lots of color in this post to break up mostly brown and white winter color outside my window! 

U.S. Breaks Record for Billion-Dollar Climate Disasters in 2020 | Smart News | Smithsonian Magazine – Not a good record to be breaking…and they happened during a pandemic year too. There were 22 disasters that caused at least $1 billion in damages across America in 2020.

Q&A: Global Insect Declines Due to "Death by a Thousand Cuts" | The Scientist Magazine® - In every case researched….it’s not just one thing that caused the decline…it a cluster of primary factors (6 or more) and then other factors that are difficult to quantify.

Texas Wind Power Dominates Coal In Crossover Year – Hurray! Hopefully, the coal plants will begin to phase out in Texas and across the country as they become less and less competitive with renewable sources of power.

On the road to invisible solar panels: How tomorrow's windows will generate electricity -- ScienceDaily – I am always reluctant to consider replacement windows….but if they were cost effective solar panels…that would tip the decision toward ‘buy’!

Caligula's Gardens, Long Hidden Beneath Italian Apartment Building, to Go on View | Smart News | Smithsonian Magazine – A subterranean museum beneath the streets of Rome to open this spring.

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.

Older forests resist change, climate change, that is -- ScienceDaily  - A study from the University of Vermont. But there are a lot of other changes in the forest too – the advent of non-native diseases like emerald ash borer and the explosion of deer populations so that there is a lot less understory in the forest (and few young trees). Is the net still that old forests resist change more effectively than younger ones?

Top 25 Wild Bird Photographs of the Week: June – National Geographic Society Newsroom – The always beautiful series of bird pictures.

Expanding the temperature range of lithium-ion batteries ScienceDaily – I’ve noticed the battery in my Prius Prime does not last for as many miles in the winter as it does in the summer. It’s one of the issues I want improved before I buy my next EV.

Chattanooga Becomes First U.S. Airport to Run Entirely on Solar – YaleEnvironment360 – Congrats to Chattanooga on this milestone. Evidently the first airport to do it was Cochin International in Kerala, India which went 100% solar powered in 2015. I’ve noticed a lot of US airports have fields of solar arrays…but maybe they haven’t also installed batteries to make the airport 100% solar powered.

You Can Now Tour the Tunnels Beneath Rome’s Baths of Caracalla – Smithsonian – A little Roman history linked to a place where tons of wood were burned per day to keep the fires going so that the caldarium would have hot water…where 18.5 gallons of water per second were consumed…copper tanks and lead pipes.

Timed release of turmeric stops cancer cell growth – ScienceDaily – Part of the search for gentler treatments for children with osteosarcoma.

A Tale of Contrasting Rift Valley Lakes – NASA Earth Observatory – Lake Tanganyika and Lake Rukwa as viewed from NASA’s Aqua satellite.  Deep and shallow. Salty and fresh. Brown and Blue.

Alibates Flint Quarries National Monument: Holding History in Your Hand – National Parks Traveler – I had to look up where Alibates Flint Quarries National Monument is located. It’s in the panhandle of Texas, north of Amarillo. I might go someday…on the way to somewhere else. The route would probably pass through the small western Oklahoma town where I was born.

Grand Canyon will soon be a dark sky park – Smithsonian – The park service has retrofitted lights to make it happen. This could be a good reason to camp in this national park!

What does the dust in your home mean for your health? – The Conversation – Thought provoking post. About one third of the ‘dust’ is created inside by ourselves and our pets, food debris, fibers from carpet/fabrics, particles from cooking plus chemicals like flame retardants. Are they toxic? There is ongoing research. Re outdoor sources – lead is the one of most concern.
