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.

Dragonflies Reveal Path of Mercury Pollution – Dragonfly larvae collected from 150 national parks and then analyzed for mercury revealed: in arid regions, mercury comes from snow and rain, while in wetter, more forested areas, airborne mercury clings to leaves, which then fall to the ground, where the toxin spreads.

Komodo dragons have iron-coated teeth to rip apart their prey – A clue to how dinosaurs like Tyrannosaurus rex killed and ate their prey.

COVID-19 devastated teacher morale − and it hasn’t recovered - A National Education Association survey of members found that, as of late 2022, a staggering 55% of educators were thinking of calling it quits because of: eroding sense of safety in the school, intense and unrelenting workload, lackluster leadership and changing expectations, and cuts in jobs and budget. Better pay is a start. I was disappointed that this article did not suggest more than that.

25 Stunning Images of the Cosmos from the Chandra X-Ray Observatory as It Celebrates 25 Years in Space - As NASA continues to grapple with a limited budget this year, Chandra is in danger of ending up on the agency’s chopping block and the program faces cuts in funding.

National Park Fun Facts: Petrified Forest – I’ve been to Petrified Forest National Park several times….still learned something from this post.

Art Bites: Michelangelo’s ‘David’ Was Carved Out of a Flawed Marble Slab – Some history of the famous statue.

8 Tips for Maximizing Your Home Solar Savings in 2024 – I am beginning to read articles like this…we will probably put solar on our house within the next year.

Why Covid-19 is spreading this summer – We’ve got to stop thinking about COVID as something that is like the flu…it isn’t.

Saving Dixie: 24 Hours Caring for a Wallaby Joey – The mother killed along a highway….and the Joey discovered alive…fortunately by someone who was willing to take care of him long enough to get him to an experienced wildlife carer.

Happy 50th birthday to the UPC barcode - While the world has changed a lot since the mid-1970s, the Universal Product Code (UPC) – what most people think of when they hear the word “barcode” – hasn’t. The code first scanned on a package of gum on June 26, 1974, is basically identical to the billions of barcodes scanned in stores all over the world today.

Zooming – July 2024

/

As I reviewed my group of zoomed images from July, the favorite subjects of the month emerged: hot air balloons, animals (birds, butterflies, a squirrel), museum and monuments, and (of course) plants dominated by flowers. The places included areas close to home, Springfield Botanical Garden, Oklahoma City (First American’s Museum and Oklahoma City National Memorial), Tulsa (Philbook Museum), and Joplin (Wildcat Glades)

The hot air balloons are from a Balloon Glow event. They didn’t leave the ground!

I enjoyed the pottery room and garden structures at the Philbrook, the light of late afternoon as I walked around the Oklahoma City National Memorial, and the wall art in the First Americans Museum).

Animals included a robin, a green heron, a skipper, a swallowtail (not sure what kind), a fox squirrel, and a juvenile male mallard.

And then there were plants. Most were flowers but there were seeds (dandelion puff), a pine cone, and olorful new redbud leaves.

It was a good month for photography and being outdoors. Only the pot and the wall art are indoor images.

Then and Now – Photography

/

Photography has changed a lot between the 1960s and now.

My mother was the photographer in my family and, as we got old enough, she allowed us to use her camera. It was an Instamatic that had a flash cube option. Film was expensive enough that we were careful to make the most of each shot. I remember sending off the rolls of film to be developed…another expense. She had taken pictures of us as babies earlier (in the 1950s) – with a camera I don’t remember – and the images were all black and white. By the mid-1960s, there are more family images in color. She often wrote on the back of the pictures: date, names of people, location.

Cameras that produced digital images became broadly available in the 1990s and now a lot of images are produced with our Smartphones. The two ‘cameras’ I used now are a Canon Powershot SX70 HS and an iPhone 15 Pro Max. The Canon is best for instances where I need the optical zoom capability (for bird and butterfly photography, for example) and I find that I can hold it steadier than the phone (i.e. the form of the camera is easier to ‘hand hold’ than the phone) The iPhone is best for macro photography. The iPhone also has the advantage of being with me almost all the time.

There are many advanced functions on both cameras. The only one I find that I use is the ‘night scene’ one that stacks low light images into a single image. Both of my cameras have the function…and it works well.

Digital cameras allow easy review of pictures immediately which shortens the photographic learning curve – no waiting until the film is developed to see if the image captured was as anticipated. I love to experiment with different settings to create high key images…and reduce the ‘burn out’ in part of the image on sunny days.

There are a lot of ways to edit pictures now – both in the ‘camera’ and post processing. I choose not to use any of them except cropping. It makes me uncomfortable to change an image to something the camera did not ‘see’ --- and it’s not something I want to spend time doing. I challenge myself to get the image I want with the camera I have! With the optics and image stabilization that cameras have today that is not as hard as it was in the 1960s.

Previous Then and Now posts

Missouri Master Naturalist Orientation

/

I went to an orientation session about becoming a Missouri Master Naturalist last week. The meeting was held at the Springfield-Greene County Botanical Center (the building in the Botanical Gardens). I spent a few minutes photographing some flowers (one with a bumblebee) in the Master Gardeners area before I went into the building.

The session was an overview of the process to become a Missouri Master Naturalist and then an informal time to talk to people that were already Missouri Master Naturalists. It was a learning experience….confirmed my decision to start the training and participate as soon as I can in volunteer opportunities. I’ve already noticed some differences between the way Maryland and Missouri implemented their Master Naturalist program…but the idea at the core is same and there are a lot of commonalities in the types of training and volunteering – which is the motivation for me! I’m excited to get started in September. It is the same type feeling I had toward the end of summer during my school years.

Wildcat Glades

/

My husband and I visited Wildcat Glades one morning last week. He did not feel up to hiking, so we did some photography near the Nature Group buildings. There were several varieties of sunflowers. I did some macro photography with my phone (iPhone 14 Pro max); my favorites are the landscape oriented one and the flower with a petal across its center…a shy sunflower.

I also took some others with my bridge camera (Canon Powershot SX70 HS) since I couldn’t get close enough to them with the phone

The Queen Ann’s Lace was in a grassy area…so the bridge camera’s zoom was used for those one too.

There was a small water feature that was almost surrounded by taller vegetation.

There were several birds (Eastern bluebird, House Finches, Eastern Phoebe) that I photographed although the cloudy day was not great for bird photography. We’ll have to visit on a sunny day next time.

One insect was still for long enough for me to go into macro mode again!

Our Missouri Neighborhood – July 2024

/

There is always something to see in walks around the ponds in our neighborhood…bits of nature thriving even in an area dominated my manicured yards: a dandelion puff (hurray for some deep rooted plants in the turf), a fat robin (there must be plenty of worms here), clover in bloom (making nitrogen available to other plants), and magnolia flowers (the bee had just flown away).

There are always turtles in the pond. One on the bank looked like he was waving at me!

I stop at the bridge to look at the sheet of water flowing into the first pond – runoff from rain or sprinkler systems running too long. I look for ripples and collections of debris to photograph. The feather caught my attention first….then the leaves and green clippings…a background of algae.

The large redbud near the pond was damaged by a storm a year ago. There is new growth from the large branch that had to be removed. I like the way the new leaves start out reddish…turn a light green…they will get even deeper green as they age.

Most of the fish I see in the ponds are small and gray or brown…but there is at least one monster koi (about 2 feet). Hopefully if someone catches it, they will not return it to the pond!

Finally – a fresh feather on the path that had been sprinkled by a neighbor’s automatic sprinkler system!

Why US schools need to shake up the way they teach physics - As the economy becomes more tech-centered, understanding physics is critical. Yet the number of Americans with a solid grasp of physics is dwindling. Learning physics can better prepare you for a role as an aerospace engineer, software developer or environmental scientist, to name just a few. Shifting the way physics is taught so that students see how physics influences their daily lives with examples from sports, extreme weather or baking and cooking rather than rote memorization of formulas with examples from history would increase the number of students mastering physics and prepare them for the future…which is what education should do.

The Smithsonian Acquires the Earliest Known Photograph of an American First Lady – A daguerreotype of Dolley Madison from 1846 when she was 81.

The Hunt: What Happened to the Great Sphinx’s Nose? – The nose was gone well before Napoleon’s time.

NASA Returns to the Beach: Assateague on the Move – The changes in the barrier islands between 1985 and 2019 shown in images from NASA satellites.

The State of Electric School Bus Adoption in the US – Every U.S. state, except Wyoming, has electric school bus commitments. I hope the adoption has the momentum to continue for the health of child and the environment! As of December 2023, 3,700 electric school buses had already been delivered and 4,800 were awarded/ordered.

Huge firework displays will mark 4 July in the US, but the nation's air quality will suffer - Fireworks generate large amounts of smoke, which can have a visibly negative impact on air quality, but they also release other pollutants that are harder to see. In some areas, the concentration of fine particulate pollution known as PM2.5 can be between 1.5 and 10 times higher than normal on the night of 4 July and the following day. These fine soot particles have been linked to a range of health problems including asthma, heart disease and low birth weight. Another negative for fireworks: One analysis of wildfires on federal land in the US over a 37-year period from 1980 found that 11,294 of nearly 600,000 fires over that period could be attributed to fireworks. Two thirds of these occurred in the two-week period around 4 July. There are concerns that perchlorate (used as a propellent in fireworks) contamination can find its way into drinking water, where high levels of perchlorate can interfere with human thyroid function. --- I hope to see more drone shows available in the coming years.

Weaker Ocean Circulation Could Worsen Warming – A new modeling study finds that slowing currents could disrupt the upwelling of nutrients from the deep ocean to the surface, starving the phytoplankton that absorb carbon. The result is that, not only would the ocean absorb less carbon dioxide from the atmosphere, it would also unleash more carbon dioxide from its depths, leading to further warming.

See Ten Awe-Inspiring Images from the Astronomy Photographer of the Year Contest – Beautiful images. My favorite is the solar prominence image.

Proteins and fats can drive insulin production for some, paving way for tailored nutrition - Production of the insulin is much more dynamic and individualized than previously thought. A subset of the population appears to be hyper-responsive to fatty foods. As a next step, the researchers hope to expand their work into clinical studies that would test insulin responsiveness to carbohydrates, proteins, and fats in a real-world setting, and to begin developing personalized nutrition approaches based on the findings.

Clever pupils don't need to attend academically selective schools to thrive – A study from Australia that followed students for 11 years. At ages 19 and 25 there was little difference between the educational and employment outcomes of children who attended selective schools versus non-selective schools. For example, the study found that while 81% of selective school students went on to secure a job or university place at 19 compared to 77.6% of pupils from non-selective schools, this difference disappeared when the students were matched on key characteristics, including socioeconomic background, gender, and geographical location.

Our Missouri Yard – July 2024

/

The wildest part of my yard is the wildflower garden I planted last summer.

In front of the wildflowers are some pumpkin vines, lambs ear, and fragrant sumac. Behind the wildflowers there is a rose bush that has died back to the roots during both winters we’ve lived in the house but has come back each year to form a low bush…blooming small red roses.

That area is always a good place to do some macro photography with my iPhone 15 Pro Max. I’ve noticed that the native plants tend to harbor more insects although most of them are quite small. We’re missing the big butterflies in our yard too.

When I mow the grass, I stop to photograph anything I find of interest…like the shell of a robin’s egg (was it taken by predator or did the young hatched and the parent clear the nest?) and a plant that grows reliably by our mailbox.

There are frequently mushrooms that come up on the area where a tree was cut down (and the stump ground up) before we moved to the house. This month there were at least 2 different kinds.

One of our pine trees is not old enough to produce cones…but the other one is prolific and I wince when I run over a cone with the lawn mower (they probably cause the blade to get dull faster). The cones look good with green needles – or grass – around them!

I still have a few areas of the yard that I have not mowed this year. In one area – violets have escaped from the flower bed and spilled out into the unmowed area. I mowed some of no-mow May area and the clippings are slowing/stopping grass from growing there and the violets are moving there too! I am getting other ideas on how to extend the flowerbeds in a way that results in less need to use the weed-eater…and overall less lawn….that remains compliant with the Home Owners Association of our neighborhood.

Springfield Botanical Garden Gardens

/

Last week my husband and I visited the Springfield (Missouri) Botanical Gardens when the temperature was warm…not yet hot. Our first stop was the pollinator garden – hoping to photograph some butterflies. There were many plants blooming around the butterfly house (we were there a bit before it opened) but we only saw some skippers around a clump of cone flowers; I had been hoping to see some Monarchs or tiger swallowtails or zebra swallowtails, etc. so I was a little disappointed. But I enjoyed trying to capture the shape of skipper’s eye.

I reverted to taking pictures of plants…the new growth of a young tree, some native honeysuckle, the different greens of a redbud, some hibiscus. I’m not sure what the pink flower is; it was planted near the Botanical Center.

The daylilies were still beautiful but past their peak. There were two gardeners taking off spent blooms while we were there.

I took two perspectives of the Monarch sculpture/playground. I hadn’t noticed before that the mouth of the caterpillar is chomping on the leaf! The area is well maintained…no peeling paint.

We were only in the gardens for about an hour, but the day was getting hotter. We were both glad we had water bottles in the car!

Philbrook Museum of Art

/

On our way home from Oklahoma City we stopped in Tulsa to see the Philbrook Museum of Art. We started in the gardens before the day got too hot to enjoy them. There were plenty of plants and water features…sculptures and activity areas (like creating poems with word stones).

The garden on one end of the house was probably my favorite because there were swings in the metal arches. My daughter and I sat in one and coordinated our pushing off (no brakes)! There was a zinnia that had been broken and dumped nearby (picture taken when we stopped the swing…just before leaving it).

Inside I enjoyed the Native American themed rooms – particularly the mosaics and pottery. The pottery was a mix of historical and modern pots. I have been sensitized by my visit to the First Americans Museum to think more critically about how some of the historical collections were created.

There were views of the gardens from the museum…a different perspective than walking through the gardens.

I thought about the building as a residence and decided it was too big to be comfortable as a home! The house was built in the 1920s for Waite Phillips and his wife; it was donated to the city of Tulsa in1938 and opened as the museum in 1939. I noted the fireplaces and some of the columns/ceilings that were obviously original to the house. They work well as a museum.

One of my favorite items was titled ‘Texas Seed Pod’ made of porcelain by Janet A. Frankovic in 1990.

We learned that the museum/gardens are decorated for Christmas…and my daughter and I already making tentative plans to visit again in December!

Pair of Resting Cuckoo Bees Wins the Royal Entomological Society’s Insect Photo Competition – Wonderful images of insects. My favorite is the Wavy-lined Emerald Moth (“A forest gem”).

The Role of Commons in Our Future Resilience - The climate and biodiversity crises will make collective land and water resources the source of future cooperation and conflict. If our commons aren’t governed well, we can have a “future of global violence.” Balancing the needs of local communities and conservation and restoration will require strong relationships between governments and the people who depend on commons for their livelihoods and culture.

Study shows how liver damage from stress and aging might be reversible – The study showed that aging exacerbates non-alcoholic liver disease by creating ferroptic stress, and by reducing this impact, we can reverse the damage.

Extreme Heat’s Far-Reaching Impacts - In addition to the expected impacts — dehydration, heat exhaustion, and heat stroke — heat can also endanger pregnant women, impact sleep patterns, and increase irritability, depression, and suicide rates. Heat is also associated with higher rates of violence and aggression, including intimate partner violence and gun violence.

The chemistry of Polaroid photography – The technology behind taking a picture and printing it instantly.

Cooling Solutions for Cities That Lower Surface & Air Temperatures – Some productive and appealing ways to cool urban heat centers.

Funny Early Entries of the 2024 Comedy Wildlife Photo Awards – Images that will make you smile!

Climate change and sea level rise pose an acute challenge for cities with combined sewer systems - Some 40 million people currently live in areas served by combined sewer systems (in places like Philadelphia, New York, and Boston) that are at increasing risk of being inundated by untreated sewage during floods.

Ancient Egyptian Scribes Were Worked to the Bone - Scribes sat in cross-legged or kneeling positions for long periods of time, hunched over paper and ink. Such activity was bound to overload the jaw, neck and shoulder regions. 30 skeletons of scribes from a northern Egyptian cemetery were examined. Much of the damage was found on the skeleton’s right sides, with the right knee being an especially common point of osteoarthritis, possibly because scribes repeatedly squatted on their right legs, the researchers theorize. And ancient Egyptian iconography commonly depicts scribes writing with their right hands. The posture impacted scribes’ backs.

Pronghorn Place: Preserve Protects Wildlife Migration Route – About the Flat Ranch Preserve on the outskirts of Yellowstone National Park…what has been learned about the Pronghorns migrating through. It reminded me of the pronghorns I saw at Sevilleta National Wildlife Refuge (New Mexico) in 2018.

Museum of Osteology…then Ducks

/

The Museum of Osteology is another museum my daughter and I visited on July 4th. It is a short drive from the First American’s Museum in Oklahoma City. It is a small museum with lots of skeletons; I was glad we were there when it wasn’t crowded. I found myself doing comparisons – which animals have the more neck vertebrae (hint: it isn’t the giraffe) and which animals walk on their toes. There was a whale skeleton mounted from the ceiling that brought back memories of the one in the Smithsonian’s Natural History Museum. There was a case of cat skulls whose health problems manifested in their bones and sclerotic rings of owls that prevent their eyes from moving within the socket. I didn’t see any bird skeletons with spurs although I don’t thing the collect included a peacock skeleton.  I also noticed that the skull of a gila monster has bumps that seemed to match the bumps of its skin!

After the Osteology Museum we headed to Norman to check in to our hotel then to Brandt Park where my daughter had seen a lot of ducks during a previous visit. There were more ducks that she remembered and almost all of them seemed to rush toward us when we got there! There were a lot of juvenile ducks and maybe they thought we were bringing food?

There was a white domesticated duck – and one that might have been a daughter of that duck.

There was one female with a juvenile that looked a lot smaller than the other young ducks and the female seemed very attentive: maybe the last of a late brood?

We headed back toward Oklahoma City to visit the memorial there when it began to sprinkle in Norman. The clouds were very thick. With my daughter driving, I was free to photograph the sun just barely showing from the edge of the cloud layer.

First Americans Museum

/

My daughter and I visited the First Americans Museum in Oklahoma City at midday on July 4th. It was a hot day, but I walked around the circular courtyard outside the entrance. I took pictures of the front and back of each of the columns on the outer rim of the courtyard – fire and water are the ones I picked to show below. I realized it was too hot to do much else outside. I’ll come back sometime when it is cooler to find out more about the mound.

The restaurant was not open (although we did pick up some recipe cards at the door); we had lunch at the café….at tasty turkey with cranberries and greens wrap and cheesecake. There is a building with a sun symbol on the side…lots of construction in the area…it will be changing a lot in the next few years as projects are completed.

Beginning our stroll through the exhibits…I enjoyed different media and the messages of tragedies…and survival…of the cultural heritage that emerges in modern form.

The film of creation stories for the tribes that were in the pre-Colonial area that is now Oklahoma was particularly well done. I took some quick pictures with my phone.

There are images on the walls that are memorable. The first one has a lot of detail (click on the image below to see a larger version) including a silhouette of a space shuttle! The second one is a repetitive motif that is used on items like key chains and mugs and glasses in the shop. I bought a mug because I liked the motif so much!

There is much to learn in this museum that is sobering and sad…but also uplifting. It is worth visiting more than once.

Fireworks on July 4th

/

My daughter and I were traveling on July 4th. Our original plan had been to enjoy the fireworks in a park in Norman, Oklahoma but it started raining around 6 PM and it didn’t look like the rain would clear until much later; the program was going to be delayed, at least.  

The radar indicated that it wasn’t raining in Oklahoma City so after dinner we headed into the city to see the Oklahoma City National Memorial at the site of 1995 bombing of the Murrah Federal Building. The museum was closed…we went to see the grounds: the 168 empty chairs representing the people that perished (small chairs for the children), the reflecting pool, the gates of time (the peace before the blast at 9:01 and 9:03 the first second of recovery), the Survivor Tree (an American Elm), and tiles made by children…sent to Oklahoma City after the bombing. The sun was getting closer to the horizon and it began sprinkling as we were getting ready to leave. It was a poignant place…flags had been placed by each chair in celebration of the 4th of July.

As we drove back to Norman, there was harder rain, lots of lightning. We began to wonder if the lightning would cause the city to cancel the events that were planned in the park. It was very dramatic – cloud to ground and cloud to cloud. We were glad to get back to the hotel.

We enjoyed the lightning show from our hotel window. The rain tapered off, but the lightning continued…with almost no thunder. We started to see some fireworks – not professional shows but clearly people that had planned their own fireworks event. Looking at the map – we expected to see the fireworks in the park at some point but the time it was schedule came and went. Lightning was still lighting up the sky. We decided that the show must have been canceled. About 5 minutes later we heard a barrage of fireworks sounds…we looked out the window again and it was obviously the fireworks in the park – high, loud, a steady stream of bursts for at least 15 minutes! I took pictures through hotel window. Toward the end, it was obvious that there were a lot of smoke in the air from the fireworks…they began to look like science fiction images of explosions inside a nebula.

I’m seeing more stories about how environmentally unfriendly fireworks can be…impacting air quality and then the remnants of the explosions (some toxic) drifting down over a wide area. And many pets are panicked by the sounds of fireworks. Evidently some places are moving toward drone light shows rather than fireworks. Maybe I’ll find one of those shows next year. I appreciate the effort Norman, Oklahoma put in for their event this year…even though I ended up observing it from my hotel window!

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.

Extended maternal care central factor to human other animal, longevity – In species where offspring survival depends on the longer-term presence of the mother, the species tends to evolve longer lives and a slower life pace, which is characterized by how long an animal lives and how often it reproduces.

The 'gene deserts' unravelling the mysteries of disease - Less than 2% percent of the human genome is dedicated to coding for genes which produce proteins, while much of the remaining 98% has no obvious meaning or purpose. But scientists are slowly managing to accrue information about the ‘gene deserts’ apparent purpose and why they exist.

These Stunning Butterflies Flew 2,600 Miles Across the Atlantic Ocean Without Stopping – Painted Lady butterflies spotted in French Guiana where they are not usually found. Sequencing the butterflies’ genome revealed that they were related to African and European painted ladies – not North American. And looking at weather data revealed that wind conditions in the weeks prior to the sighting were favorable for the butterflies moving from Africa to South America.

Simple test for flu could improve diagnosis and surveillance - Fewer than one percent of people who get the flu every year get tested, in part because most tests require trained personnel and expensive equipment. The current version of new test is a low-cost paper strip that distinguishes between influenza A and B and subtypes H1N1 and H3N2. It works at room temperature…takes about 90 minutes. They are working to reduce the time to 15 minutes.

To Save the Red Knots, Look to Blue Carbon – Red Knots migrate over 9,000 miles to the Arctic to breed. Along the way they stop for meals of mussels and clams in coastal areas. This post highlights 6 projects from around the world that are restoring those area…for the red knots and the health of the planet.

Photography In the National Parks: Two Cave Parks Above and Below – Wind Cave National Park and Jewel Cave National Monument. Full of ideas for photographing inside caves and above them! My first thought was to see if there is a trail that goes over the top of Sequiota Cave and Spring near Springfield MO (we did a boat tour of the cave last spring).

Surprising phosphate finding in NASA's OSIRIS-REx asteroid sample – Remembering when we went to the launch of the mission in September 2016.

Swift Parrots and the Heartbreak of Rare Species – Endangered Australian parrots…with only an estimated 500 birds left in the wild. “We conservationists bear witness to so much loss: of species, ecosystems, and the places we know and love. Often, it feels like we’re watching extinction in real time, powerless to stop it. But there is value in staring these losses in the face. Value in bearing witness to a rare parrot with an uncertain future, knowing full well I might mourn its extinction in a few years time. If the worst happens, at least I will have cherished it while it was here.”

A Big Picture of the US Housing Market - High interest rates, supply constraints and growth in home insurance premiums (particularly in states like California and Florida) are all driving housing costs. There is some news that’s more positive. Nearly 450,000 new apartments were finished in 2023, the highest rate in about three decades. However, average rents remain above pre-pandemic levels in most markets.

Sheep & Solar: A “Beautiful Symbiotic Relationship” - When solar farms use sheep instead of mowers for vegetation management, they minimize burning fossil fuels, and costs associated with labor are also reduced. Investment costs for a solar farm might include water tanks, troughs, a small water pump to fill the troughs, predator-proof fencing, and dividing into sections for rotational grazing. The sheep eat the tall grass, weeds, and clover, and their chomping inhibits the vegetation from blocking the panels. Their steady consumption of forage on the land prevents grassy plants from growing high enough to block sunlight from reaching the panels, maintaining the productivity of the array. Sheep are the most appropriate ruminant species when it comes to vegetation management on solar farms because they are too small to damage the panels when rubbing against them, and they are not predisposed to chewing on wires or jumping on the panels.

Green Heron in the Neighborhood

/

The forecast said the day was going to be very hot and humid…so I was out taking my daily walk at 7 AM. As I neared the first pond – a bird flew out of the shallows and land at the other end of the pond. I managed to use the zoom on my camera to see what it was: a green heron. It was standing up tall making it a little easier to spot. It is surprising how well their coloring blends into the environment.

They are occasional visitors to our neighborhood ponds. There is not enough habitat here for them to be residents. This time the bird was looking for breakfast. It stalked down through the grass to the edge of the pond – eventually sitting   at the edge of the water. The morning light was excellent for photography.

A grackle flew down nearby for a drink.

I was walking slowly closer to the heron…although across the pond from its location. The grackle startled it enough for it to move along the bank and then up into the grass again….before it flew away.

Balloon Glow – June 2024

/

Last June, my husband and daughter attended the annual Balloon Glow in Ozark, MO’s Finley Park while I was in Dallas; they sent me pictures  and I wrote about the vicarious experience….also realized that I wanted to attend the event this year. This year it was sunny rather than thunder storming before the event. It was hot a muggy. That did not deter the crowds at all. We parked in overflow parking and got to the the field where the balloons were going to be inflated shortly before dusk. Our timing was near perfect. The teams were just starting to fill the ballons with hot air. The first one to come upright was an old-fashioned one with gold swags on the side. Others quickly followed.

We took a break to buy lemonade and snow cones. We walked around the roped off perimeter surrounding the balloons to see different vantage points. As it got darker, the periodic burn of the heaters lit up the ballons and made percussion type noises. It was a dramatic and beautiful summer event.

I was drinking the ice melt from my large lemonade but still felt dehydrated when I got home. I took a picture of the moon that was almost in the treetops ….and then focused on rehydrating before bedtime!

Zooming – June 2024

/

Lots of opportunities to capture images of some of my favorite subjects in June 2024: big cats, birds, butterflies, and (of course) flowers. Some were close to home (Dickerson Park Zoo, Lake Springfield Boathouse) while others were from our two days in Eureka Springs, Arkansas.

Big cats. The animals are obviously in some kind of enclosure. The cheetah at the Dickerson Park Zoo was photographed from a high deck over the enclosure…maxing out the zoom capability of my camera; it was the only one that did not have a fence between me and the cat! The other three images had the fence challenge; it is most visible in the lion image. It’s always a little unnerving to realize that a tiger, even looking very relaxed, is following me with his eyes!

Birds. I always see birds the best after I get home and look at my images on a big monitor. The optics of the camera allow me to get very close views without being close to the bird! The peacock (head and feet) images were taken at Dickerson Park Zoo and the bluebird and purple martin were near the Lake Springfield Boathouse.

Butterflies. The three butterflies on rocks were taken in the parking area of the Eureka Springs & Northern Arkansas Railway. The insects were fluttering around looking for moisture. The butterfly on a flower was in the meadow near the Lake Springfield Boathouse. Butterflies are as challenging to photograph as birds, but it does help to keep a distance. If the insects are on a flower or looking for moisture, they might sit for long enough to capture an image; sometimes a little bit cooler temperatures help too.

Other wildlife. The lizard shedding its skin must have been terrified of the people walking on the boardwalk; it would have felt the vibration. We stood back once we realized it was there…and I got my picture. The same was true of the cicada although it flew to the post (I saw it in the air and followed with my camera already zooming) and then flew again within about 30 seconds.

Flowers. And then there are flowers.  I love to take pictures of flowers filling the frame. I like that using the zoom blurs the background – often to various shades of green. Depending on the light, the background can also go black (the leaf on a vine). My strategy it to capture the ‘as is’ in a way that appeals to me. The blade of grass almost like a pointer to one of the stamens in the day lily image was a bit of serendipity!

As we near the end of the month – I am savoring these zoomed images!

Gleanings of the Week Ending June 29, 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.

The Electric Revolution of Gardening Tools is Here – Hurray! We’ve been completely transitioned to battery powered yard tools for a few years now. I wouldn’t be mowing my own yard without our electric mower. Our old gas-powered one was noisy and my throat got scratchy from the fumes. Now I think of mowing the yard as a challenging exercise rather than a negative impact on my hearing and lungs!

US Cities Ranked by Vehicle Miles Traveled – As I read the article, I wondered where Dallas/Fort Worth fit since they were not on the top 10 list. I went to the source cited in the article and found that Dallas/Fort Worth was 19th.  Other Texas cities are high too – San Antonio at 14, Houston at 18 and Austin at 22.

See Frida Kahlo in Her Element in a New York Show of Rare Photographs – There is a picture of her (and Diego) viewing a solar eclipse in 1932 (Detroit)!

The apple detectives hunting for lost varieties - Apple fanatics across the UK are now taking samples from very old apple trees in hopes of learning more about antique varieties, and perhaps making some surprising discoveries. That's because there are apples, documented in 19th-Century books like Robert Hogg and Robert Bull Graves' The Herefordshire Pomona, that have slipped through people's fingers.

In North Macedonia, an Ancient Lake Faces Modern Threats – Lake Ohrid - 19 miles long, nine miles wide and 945 feet deep, teeming with fish, snails, leeches, flatworms, phytoplankton, crustaceans, and more. Of the lake’s roughly 1,200 known native species, 212 of them are endemic, occurring nowhere else. It faces growing threats, including from overfishing, nutrient pollution, invasive species, booming tourism, unregulated building, official neglect, and perhaps the most inexorable challenge of all, global warming.

Rare White Bison Calf Born at Yellowstone National Park - Photographed on June 4, as a group of bison crossed a road with traffic stopped.

A supermarket trip may soon look different, thanks to electronic shelf labels - This month, Walmart became the latest retailer to announce it’s replacing the price stickers in its aisles with electronic shelf labels. The new labels allow employees to change prices as often as every ten seconds. They haven’t come to the Walmart near me yet…I’ll be looking for them every time I shop there.

A new way to measure aging and disease risk with the protein aggregation clock - Although there are other "clocks" to measure ageing and health, most of them are based on nucleic acids like DNA. A biological clock based on proteins could be a useful complement to these existing clocks, as proteins are among the most abundant molecules in cells and are crucial for all cellular functions. With the help of such a protein aggregation clock, scientists and doctors might move one step closer towards helping people age healthily and preventing age-related diseases.

Tiny beauty: how I make scientific art from behind the microscope – Great illustrations…worth scrolling through.

New metric for blood circulation in brain to better understand dementia - By accurately measuring how pulsatility is transmitted in the brain, researchers can better understand the underlying mechanism of brain conditions (including Alzheimer’s disease and other forms of dementia) and potentially guide development of new treatments.

Macro Photography – June 2024

/

My yard is full of subjects for macro photography this time of year.

The wildflower garden is in its second season and is very lush after the spring rains…both flowers and insects abound.

The area in our front yard that once hosted a large tree (before we moved here) now has mushrooms after almost every rain. It is surprising how quickly they can develop and then degrade to black goo.

One of the daylilies I planted last under the red maple is blooming this year. Hopefully the plant will propagate to surround the trunk. There are enough buds to appreciate this year from a photographic standpoint.

I’ve let the Virginia Creeper that came up in the front flowerbed cascade over the castle rocks. Mowing the lawn contains it once it is in the grass. I like the foliage now and it will look great in the fall when it turns red.

I’ve found several eggs in the grass and always try a photograph. This one was white. The cracks in the shell around the edges and inside appealed to me. The grass offers a sense of scale.

I took pictures of two small branches blown off by an overnight storm – making a macro image of the part that interested me the most.

The plant by the mailbox is full of buds. Another plant of the same type is near the house, but its buds always get eaten and there are holes in the leaves!

The two ‘hens’ that I bought last year at a farmers’ market have more and more chicks. There were only 3 chicks at the beginning of the season. I count more than 30 chicks in this image when I look at it on a bigger monitor!

I enjoy ‘filling the frame’ with magnified images from my yard!
