Gleanings of the Week Ending October 12, 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.

Who Was Buried in Spain’s Megalithic Necropolis of Panoría? - More women than men were buried in Panoria, where human remains were interred in collective burials between 4,100 and 5,600 years ago.

On Navajo Lands, Ancient Ways Are Restoring the Parched Earth - Traditional rock and stick structures, similar to those used by Native peoples long before Europeans arrived on the continent, are not only delivering water to crops they are also restoring the watershed and those of neighbors, helping to sequester carbon, and reviving this high-desert ecosystem…. an opportunity to begin developing localized food economies.

Megadiverse flowering plant family on isolated islands – A high number of evolutionary events -- occurred in the aster family (daisies, sunflowers, and asters) within relatively short time periods on many islands worldwide.

Why is Mount Everest so big? New research highlights a rogue river – but deeper forces are at work - Everest is around 250m taller than the other great peaks of the Himalayas. It is also growing by about 2mm each year – roughly twice as fast as it has been growing on average over the long term. The Arun river’s course changed around 90,000 years ago, eroding away rock that was weighing Everest down – and the mountain has bounced up in response, by somewhere between 15 and 50m. However, the “fundamental cause” of the peak’s size is the tectonic processes that create mountains.

Researchers Grow an Extinct Plant From a 1,000-Year-Old Seed - Israeli researchers have grown the seed of a previously unknown species of flowering plant into a mature tree. In the late 1980s, archaeologists excavating caves in the northern Judean desert discovered a well-preserved but mysterious seed that had likely been carried there by animals. The seed could be dated to between 993 C.E. and 1202 C.E. and that it was a unique member of the commiphora family, a flowering plant known for its aromatic resins. Chemical analysis of the leaves shows an abundance of medical properties in the leaves, and its lack of fragrance matches descriptions of the tsori in the Bible.

Rare and Elusive Australian Bird, Once Thought Extinct for 100 Years, Discovered by Indigenous Rangers and Scientists – Night parrots are generally difficult to detect—a fact that has been long recorded in Indigenous culture. The elusive species creates tunnels and nests in dense spinifex bushes and emerges at night to forage for seeds.

5 things to know from this week’s big report on cannabis - A new report from the National Academies of Sciences, Engineering and Medicine finds the disconnect between the states and the federal government is leading to fragmented policies, and risks to the public. 5 takeaways:

  1. People consume cannabis more regularly than alcohol in the U.S.

  2. Weed and vapes can be super potent and that’s not always disclosed

  3. You can get psychoactive hemp products even in states where cannabis is illegal

  4. Research on cannabis is stifled

  5. Cannabis can be dangerous, but people hear more about its benefits than risks

Biodiversity Becoming a Top Priority - A survey of 300 landscape architects, designers, and landscape architecture educators in the U.S. found that 96 percent of landscape architects are familiar with the impacts of the biodiversity crisis. 45 percent have made biodiversity conservation a top priority of their practice and another 41 percent consider biodiversity as part of their organization’s environmental ethos.

Medical imaging breakthrough could transform cancer and arthritis diagnosis - A new hand-held scanner developed by University College London researchers can generate highly detailed 3D photoacoustic images in just seconds, paving the way for their use in a clinical setting for the first time and offering the potential for earlier disease diagnosis (cancer, cardiovascular disease, and arthritis). What a boon if this could become the new standard…avoiding waiting for an imaging appointment, having to sit still for a long time, and higher cost of current technology!

Incredible Winners of the 2024 Natural Landscape Photography Awards – Couldn’t resist this collection of beautiful images to finish off the gleanings for this week.

Meadow at Lake Springfield Boathouse

I opted to drive myself the Lake Springfield boathouse last week so I could photograph the meadow/prairie and the other plantings near the boathouse before the rest of the Identifying Woody Plants class arrived. The beautyberry was spectacular! I am so glad I planted some in my yard recently and hope it makes it through the winter to be a great plant next year.

The common milkweed had already been cut down but there were several pods spilling their seeds where the plants once stood.

The asters seemed to be hosting the most insects in the meadow/prairie area. I was thrilled to see Monarch butterflies; they were large ones…the ones that go all the way to Mexico for the winter. The thistles were releasing their seeds and the golden rods were the second most popular nectar plant for insects.

It was a great day to see the meadow in fall glory!

Missouri Master Naturalist Training – Week 1

The training to become a Missouri Master Naturalist (MMN) started last week. Some weeks there is only one session…sometimes there are more sessions or field trips or chapter meetings. September and October are going to be busy months this year! The first class was at the Springfield-Greene County Botanical Center starting at 6 PM. I went a little early do some late afternoon photography in the garden areas near the building. I always enjoy the rain garden area with the duck sculpture almost covered with vegetation this time of year. There were goldenrod soldier beetles on the asters and golden rods….skippers on the asters. A mallow was beginning to fade nearby.

On my way from the rain garden to the build I noted what looked like a large basket beside the sidewalk; I didn’t try to open it.

In the raised bed near the door there were several interesting plants…including some chard and an oak leaf hydrangea in bloom.

Inside I met the rest of the people that will be in the class with me. There were handouts that included a Missouri Master Naturalist tote bag. Since we all got one, I am thinking about making some Zentangle patterns on the back so that I can easily identify my bag!

The lecture topics were History of Conservation and Insects. I appreciated that we had a break to walk around between lectures since my back starts hurting if I sit for longer than an hour!

I am using a blank book my daughter picked up at a recent conference for note taking since the activity is part of my learning strategy (forces me to pay closer attention). The charts are evidently not going to be posted or sent to us so my notes will be what I will have from the class.

I find myself comparing this class with the one for Maryland Master Naturalist 9 years ago; but realizing that whatever they do here in Missouri for training is geared for the type of volunteer opportunities available here….and the volunteer work is why I am in the training!

Lake Springfield – August 2024

We set out to the Clay Henshaw Memorial Access on Lake Springfield since we had not viewed the lake from that perspective before. It was a little too late in the morning for birding, but I took a few pictures of flowers growing in the area.

There was a large (lotus?) leaf on the water surface that had interesting patterns of green in the deteriorating leaf that curled upward at the edges.

The sun was very bright, and we could feel the temperature rising.

We headed over to the boathouse…. which is our favorite place on the lake. The area around the building is full of native plants created by the area Master Naturalists…some with seed pods already.

As we started toward the meadow, I noticed that that the purple martins have already left. There were a few birds near the feeders…and the moon was visible in the nearly clear sky.

I took pictures of dragonflies that landed on the paved path or in the grass long enough for me to photograph. Most of them didn’t…they were on the prowl for breakfast.

The thistles were attracting skippers, but I didn’t see larger butterflies feeding in the meadow.

The sunny meadow had a lot of tall vegetation…not as colorful as earlier in the season. Many of the meadow plants are producing seed now. The goldenrod has not started blooming yet.

As we got to the far side of the meadow, a bird flew into a tree. I got several reasonably good pictures: a Great Crested Flycatcher!

There are two trenches made by storm runoff in that area…and both are dry right now. It’s been a dry August here.

We turned around and made our way back to the car…pleased with our morning activity before the heat of the day became overwhelming.

Fall Meadow at Lake Springfield Boathouse (1)

We visited the meadow near the Lake Springfield (Missouri) Boathouse last week  on a sunny, but relatively cool fall morning. Near the Boathouse, I noticed some beautyberry and asters.

The large cup plant has already been cut down - the stumps of the 4-angled square stems obvious.

We noticed that the purple martin houses had been taken down; there were big mowers in the area around the boathouse as we walked toward the meadow.

A lot of meadow plants have already produced seed. The goldenrods and asters are still blooming…and a few thistles.  

The area that becomes an overflow creek during heavy rains was dry but there were some interesting plants around it:

Invasive bush honeysuckle with lots of red berries.

Seed pods of mallows.

There was only one milkweed plant I saw in the meadow…and wondered what happened to the plants I had seen earlier in the season. Perhaps they fell over, and the other plants hid them?

On the other side of the visitor center, I did find some milkweed with bursting seed ponds. The plants had fallen over but the seeds were still spilling out and floating away.

The vines in the trees were easy to see. The leaves on both poison ivy and Virginia creeper turn red in the fall! The edge of the forest is full of trees with the vines growing up the trunks and into the higher branches.

Tomorrow’s post will be about the insects we saw.

Patuxent Research Refuge – Misc.

Of course, there are other things besides waterlilies, milkweeds and goldenrod to see this time of year at the South Tract of Patuxent Research Refuge. I did some experimental photography with some grass seed heads and asters…liked the results.

The cattails are exploding with fluff. If it doesn’t float away fast enough it becomes matted around the stalk.

Many plants are going to seed in the meadow.

In the forest there are hits of color…just a few leaves at this point. Green still dominates.

There was an old jumble of trunks…some upright and others leaning over…with shelf fungus in profusion.

There is a bird blind around a collection of feeders but I wasn’t quiet enough to walk up to it without all the birds taking flight. I managed to notice finches on the feeders and mourning doves below.

Sometimes something appears that I don’t expect – like this fire hydrant in the meadow. It isn’t that far from the visitor center but far enough that I would have thought one closer would be more useful and it was surrounded by wild vegetation – a little surprise. It was rusted enough that I wondered if it was still functional.

Overall – every time I got to the refuge, I notice something that I haven’t seen before!

Macros – September 2021

My smartphone, a clip on macro lens, and Bluetooth shutter control were the gear I used for the macro photos feathered in this month’s post. They are all from a short walk in Howard County Conservancy’s Mt Pleasant from the parking area and into the Honors Garden. The set up works very much like the bridge camera (with lens, diffuser, manual focus) in that I must get close to the subject and move the phone to get the focus perfect. It has the advantage of being a lot more compact than the other set up!

The rain from the night before had left everything with a sheen or droplets of water. Often the wet increased the richness of the colors…and the shine. The thin clouds provided good, diffuse light – a good day for smartphone macro photography. The cedar was on my way to honors garden.

The seed pods on the magnolia were not flat enough to be an easy shot! The depth of field is very narrow with magnification.

I experimented with different perspectives of cone flowers

And asters. In the last picture, the depth of field gave me the blurring around the edges than I wanted.

The birds nest fungus was in a mulched area near the parking lot. Some of the cups seem to hold water!

Even grass seeds take on a different perspective in a zoomed image.

…And these are the best of the rest (note the insect hiding inside a flower)!
