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.

2021 09 IMG_9162 (5).jpg

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.

2021 09 IMG_9162 (11).jpg

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!

Patuxent Research Refuge – Milkweed and Goldenrod

/

The milkweeds are going to seed and the goldenrods are blooming at the South Tract of Patuxent Research Refuge last week – typical fall meadow views. The milkweed seed pods have burst open and are spilling their seeds to the wind. The seeds have the possibility of starting new stands of the plant next year. The stands that are healthy now will come up from the roots already well-established next spring (i.e. no seed sprouting required).

2021 09 IMG_9170 (1).jpg

My favorite picture of the morning was the very first one I took – with the dew still sparkling on the fluff and the seeds still neatly emerging from the opening pod.

Often the goldenrod and milkweed are mixed in meadow areas but there are some almost pure stands of the goldenrod. It is the hero in the fall for migrating Monarchs and other nectar feeding insects. Sometimes the plant gets blamed for allergies, but it is insect pollinated, rather than wind. People with fall allergies are more likely to be feeling the impact of ragweed pollen!

Patuxent Research Refuge – Waterlilies

/

Last week, my husband and I spent a morning at the South Tract of Patuxent Research Refuge. It’s about 30 minutes from where we live. The weather was a sunny and cool – typical early fall and a great time to be out and about.…and there were waterlilies blooming!

The first ones I noticed were in an area where the water level had recently dropped, based on the number of lilypads that were out of the water rather than floating. There was also a lot more vegetation in the water in that area other that water lilies.

Toward the end of our walk, we were between two ponds and the light was right for reflections. I liked the light pink of this first flower…even though a lilypad bisected the reflection.

The next flower I photographed I remembered to apply the rule of thirds after I took the first image….and have to admit – I like the second one better!

The visitor center was open but we didn’t go in. We’ll be back to see fall foliage in a few weeks!

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 oil-field ‘fugitive’ that can slip into the water supply – The methane leaks into ground water are yet another reason fossil fuel is problematic. The industry evidently can’t or won’t clean up…making moving away from fossil fuels as quickly as possible even more urgent – although climate change should be enough for the world to be doing that already.

Top 25 birds of the week: Brown Birds – Not all birds are colorful! Watching small brown birds can be just as much fun though.

Ancient Human Presence Revealed At White Sands National Park - Researchers Push Back Date Of Human Arrival In North America Thousands Of Years – Fossilized footprints in the gypsum sand playa deposits…dated to the Late Pleistocene.

Mexico’s Ancient Inhabitants Moved Land and Bent Rivers to Build Teotihuacán – Still more being learned from an archaeological site that has been studied for many decades. LiDAR is one of new technologies that is yields a lot of new information.

Poorly circulated room air raises potential exposure to contaminants by up to six times – COVID has prompted more detailed research on this topic…and the discoveries should be used to improve building ventilation systems to help control other air-borne diseases.

Why colorful food is good for you – I like the colors and flavors….it’s an added benefit that they are also healthy choices!

NASA’s James Webb Space Telescope Will Launch Into Orbit in December – Finally!

River research reveals scale of macroplastic pollution – A plastic bottle takes a long time to break down….450 years and requires UV light. With so many bottles getting into rivers around the world, it is important to understand how they travel…how they begin to breakdown. They are going to be around for a very long time and, right now, more are still entering the rivers.

Research shows more people living in floodplains – From NASA. Tragedies that are getting worse as population increases and climate change causes flood risk changes.

Making Beetles Pee Can Protect Your Garden – Maybe this is also a pathway to an effective way to control insects like aphids without pesticides!

High Key at Conowingo

/

On Sunday morning we left our house about 7:30 AM to drive to Conowingo – about a 1.5 hour drive from where we live. Below the dam is our favorite place to see bald eagles. This is not the best time of year, but it was a sunny fall morning – a good time for a short daytrip.  

There were some black vultures on top of a car parked near the entrance gate at Conowingo Fisherman’s Park. I had heard about it happening but hadn’t see it before. There didn’t seem to be many photographers along the fence however there were cormorants and gulls over and on the water. There were more cars than usual but apparently the owners were mostly there for fishing. We saw several with very large catfish (looked like the invasive flathead catfish). The spillways on the far side of the dam were active…but it didn’t seem like there was much water churn on our side of the river.

I had just started surveying the abutment, rocks and island with my bridge camera mounted on a monopod, when the battery connection problem that I had experienced previously began. I had to take the camera off the monopod and remove the foot to open the battery compartment and try to increase the thickness of the paper wedge I had been using to hold the battery more firmly on the contacts. I put everything back together and it still didn’t work consistently. I was able to see an adult bald eagle on the abutment and a great blue heron on a spit of rocks and gulls flying over the water --- but the camera would not work for long enough to get a good picture. So – I gave up and pulled out my small Point and Shoot (Canon Powershot SX730 HS). I was very disappointed in what I could do with less zoom than the bridge camera. So --- I opted to try some high key pictures. My first subject was large sycamore with branches that hang over the water. The color variation in the leaves was more visible with the background mostly bright white although I did one with the water partially visible.

My favorite is the one below with the foliage in the lower right corner. I can image this in a presentation with some words in the upper left!

2021 09 IMG_5244 (6).jpg

Next --- I chose to photograph the electrical towers. I was not aware of the blue (vignetting) in the upper corners until I looked at it on the monitor at home….but I like the little bit of color!

2021 09 IMG_5244 (4).jpg

One of the towers on the island in the river contained a surprise that I didn’t see until it was on the larger screen: a bald eagle standing on a nest! It is not a good eagle shot…the bird is facing away and blurry….too far away for the Point and Shoot to get a crisp image. But it shows how the eagles use of the manmade structures!

Overall – I was pleased with the morning…even though it was quite different than I’d planned!

Rough Green Snake

/

My son-in-law saw (and photographed) a rough green snake while he was hiking at Ritter Springs State Park near Springfield, Missouri. What a wonderful color! His picture prompted me to do a search to identify it…learn more about the snake.

Avery Resized_20210908_152014.jpeg.jpg

The highpoints of what I found: They are exploited by the pet trade – and people that want to keep them as pets (I’d rather they stay in the wild!). The snake eats insects and other small invertebrates - spends most of its time in trees, often near water. Not venomous. Their range evidently extends into the area where I live in Maryland, but I’ve never seen one. I’m going to start looking for them. It would be quite a thrill to see them in the wild.

Not long after I received the picture, there was a blog post from DFW Urban Wildlife that included some pictures of a rough green snake in Texas! It contained some other critters that are hard to spot in the wild. I am going to look more closely for them…hone my observation skill. It’s probably true that there is almost always more to see out in nature than we notice!

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.

20210909_090222.jpg

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.

20210909_113756.jpg

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

20210909_091438 clip.jpg

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)!

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.

Young female black bears in Asheville, North Carolina, are big, have cubs early – More research needed…it’s still not known what is causing them to be so much bigger and mature early…or if the population is increasing or not. It is clear that there are quite a few bears and lots of opportunity for interactions between people and bears – many not healthy for the bears.

The alarming risks of mixing common drugs – It is a problem that is acute in most elderly patients with good medical care. Their various doctors have gradually built up the medications…and the regime to take them all appropriately becomes daunting. Hopefully it will become best practice to constantly review and minimize drugs that are prescribed.

Work Of First African American Painter With International Reputation Explored – Henry Ossawa Tanner (1859-1937)

Hummingbirds can smell their way out of danger – I was thinking a lot about hummingbirds this past week after my success photographing one at Brookside Gardens.

Praying Mantis – I see these more frequently in the fall…but not every fall. There are so many mantis egg cases, there should be plenty to see; I need to improve my observation skills.

How much energy do we need to achieve a decent life for all? – The most important take away from this study: “energy for eradicating poverty does not pose a threat for mitigating climate change.” That is good news

The lost generation of ancient trees – The ancients are dying….and there are not enough trees old enough to replace them. There are various ways being tried to veteranize younger trees so they can play the role of ancient trees in ecosystems.

Fall Armyworms are Attacking Lawns and Crops on an ‘Unprecedented’ Scale – Hmmm…maybe this is a prompt to reduce or eliminate the grassy portion of the yard.

Mammoth Cave National Park: The World's Longest Cave Is Longer Than Before - 8 more miles mapped bringing the total to 420 miles!

Hand pollination of crops is of major importance – I was surprised that hand pollination is already used for important crops like apple, palm oil and cocoa.

Brookside Gardens in September 2021 – Plants

/

Of course – the plants are always a big draw for a visit to Brookside Gardens – never an exception to that. I did a landscape shot of the garden area the hummingbirds come.

2021 09 IMG_8675 (1).jpg

There was a plant in that garden with various stages of flowers that captured my attention while I waited from the hummingbird.

2021 09 IMG_8675 (2).jpg

I never was able to find the hummingbirds perched in the magnolia even after I saw them fly into the tree…but the tree’s developing seedpods were good subjects too.

2021 09 IMG_8675 (3).jpg

There was hibiscus blooming in a big pot to the side of our position.

2021 09 IMG_8675 (4).jpg

Turning around – I tried to capture the colors in the castor plants – leaves and seeds.

It was beginning to get a little hot, so we walked toward some shade. I was glad I had my water bottole in the back pocket of my photovest.  I can easily shorten the monopod for carrying or keep it extended to use as a walking stick. As we walked toward the rose garden – I took a zoomed picture of a datura flower. I liked the white color…gentle curves.

Maybe I was a little fixated on white since I photographed white roses as soon as we got to the rose garden.

I opted to sit on a bench in the shade under the wisteria arbor and took the rest of the photos of the morning for there! The zoom capability of my camera (Canon Powershot SX70 HS) is one of my favorite tools. I love to experiment. As I zoom beyond the optical zoom, the images tend to get a softer focus (for example, the very magnified underside of a rose below….which is my favorite flower picture of the morning).

And that was (another) enjoyable field trip/photography session to Brookside Gardens!

Brookside Gardens in September 2021 -Insects

/

While I was watching for hummingbirds at Brookside Gardens, there was ample time to photograph the antics of bumblebees in the same flowerbed. They were all over the blue/purple plants.

Further back – there was a bush that was attractive to tiger swallowtails. I haven’t seen as many of them as I usually do this year, so I was pleased to photograph a female (with blue on the lower part of the wing) and a male with battered wings.

I also photographed two skippers – one in the same area as the bees and butterflies, the other in the rose garden. They look like they are the same species male and female (looking at the difference in the end of abdomen).

All the insect pictures are using the zoom on the camera (Canon Powershot SX70 HS) rather than trying to use a macro lens. The insects are too far into the beds to get close enough for macro work…and I like having more depth of field and blurring of the background. The second image of the skipper (on the rose bud and new leaves) is my favorite insect image of the morning!)

Brookside Gardens in September 2021 – Hummingbird

/

We visited Brookside Gardens last week – getting there about 9 AM when the temperature was still very pleasant. Our goal was to see some hummingbirds in the fragrance garden. We chose a weekday to avoid the crowd of photographers with the same objective in mind; the plan worked, and we were the only ones in the area the hummingbirds frequent. This is the toward end of the season for hummingbirds and the females are the ones still around…the males are already further south. We saw and heard the little birds almost immediately.

I was using my bridge camera (Canon Powershot SX70 HS) in Program mode…mounted on a monopod. That gear works well for me because it is maneuverable and has a lot of magnification adjustable with a fingertip. The camera also has a burst mode that worked well during this attempt. It helped that it was a sunny day – plenty of light on the birds!

Even though I saw hummingbirds frequently – in the trees, in the air, quickly flitting over the flowers – I only managed one good series of images. It was feeding near the middle of the bed with flowers attractive to hummingbirds. I’ve selected the 12 best pictures from the bursts of images I took for the slideshow below.

Note how compact the body of the bird is with the feet not visible at all. The muscles it takes to move the wings so rapidly to maneuver into position relative to flowers must be in excellent condition – and require a lot of energy. The bird looked nicely rounded; hopefully this bodes well for a successful migration south for the winter.

More about out visit to the gardens over the next few days about the insects and plants we saw…

Ready to Volunteer Again

/

Over the past week or so – I’ve been attending training sessions at the Howard County Conservancy’s  Mt Pleasant in preparation for field trips that might happen this fall. With schools in the county just starting this week, there is a lot that is TBD for the fall field trips. There are more that the usual challenges: potential for COVID-19 outbreaks (vaccination and masking helps but is not 100%), shortage of bus drivers, and a higher percentage of new volunteers than in past years. The usual weather challenge for the outdoor programs seems small in comparison!

I am hopeful that there will be at least some field trips. The scheduling requirements probably mean there will not be a lot of them until October, and there might be some opportunities where the volunteer gig will be in the school yard rather than at Mt. Pleasant. Either way – being outdoors with students is something I look forward to every fall; I missed it in 2020.

The training session this past week was on a sunny, cool day after Hurricane Ida came through our area. I couldn’t resist some photography before/after the session.

Honors Garden

Sweet Bay seed pods just outside the Honors Garden – smaller than the pods of the Southern Magnolia but still looking like red M&Ms peeking out of the pod.

A little fall look with sunshine bringing out the changing color of leaves

IMG_5168.jpg

Looking again at a tree stump cut earlier in the pandemic. I noticed that the rings are somewhat concentric for the early years of the tree’s life. Then they get very closely spaced on the side toward the bottom of these image. The tree seemed to grow skewed to the left!

IMG_5176.jpg

As I got close to my car, I noticed that the old pear tree in the old orchard is loaded with fruit this year!  .

The place….the people…it feels good to be on the cusp of fall volunteering!

Texas Butterflies

/

After I shared my video of the Monarch butterfly emerging with my sisters, we started talking about the butterflies they are seeing in Texas. They are not seeing as many as they remember being around in the past….and in recent years the only times they have noticed Monarchs is in the fall during migration. One sister noticed 2 butterflies drawn to her cosmos…more than she had noticed before.  The plants are blooming profusely.

There was a Monarch that moved all around the garden. The picture shows that it is a female. The yard has plenty of nectar  for the butterfly but no milkweed for eggs/caterpillars. This time of year, a lot of plants go dormant in that part of Texas unless they are watered and milkweed usually grows in places that aren’t watered. Is this butterfly already on its way further south?

gina IMG_5125.jpg

She sent pictures of another butter asking for an ID. It’s obviously one of the swallowtails. The pictures of the upper side show clearly that it is a male pipevine swallowtail. Again – enjoying the nectar in the yard…but there are no host plants for caterpillars.

Gina IMG_5124.jpg

In the not so distant past – there would have been a lot more butterflies drawn to the nectar in her garden. Butterflies – like a lot of other insects – are declining rapidly. There are a lot of reasons…mostly derived from human activity. Hopefully our actions can begin to reverse the trend…starting now. Nectar plants are prevalent in many gardens although skewing more toward native species rather than exotics would be an improvement. Beyond that, I am going to focus on host plants and not keeping my garden so tidy that I remove chrysalises/cocoons!

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.

Entomologists Eradicated the First Asian Giant ‘Murder’ Hornet Nest of 2021 – Includes a picture of the 9 layers of the nest that was carved into an alder tree’s interior.

Turning thermal energy into electricity – It seems like this type of electricity production would have application beyond the military. Even solar panels produce heat and finding a way to automatically harness that into more electricity would be a good thing.  

Climate Change Producing More “Fire Weather” as Far East as Oklahoma – It’s not just the west coast that has a higher risk for fire as the planet gets hotter.

Aztec Pictograms Are the First Written Records of Earthquakes in the Americas – One of the pictograms matched to a 1507 earthquake that coincided with a solar eclipse!

Food systems: seven priorities to end hunger and protect the planet – A thoughtful commentary re ending hunger and improving diets; de-risking food systems; protecting equality and rights; boosting bioscience; protecting resources; sustaining aquatic foods; and harnessing digital technology.

Eating walnuts daily lowered 'bad' cholesterol and may reduce cardiovascular disease risk – There was a similar article about pecans a few days ago. I’m glad I like both walnuts and pecans! However – ½ cup is a lot to eat in one day. Usually ¼ cup is considered a serving.

Top 25 birds of the week: Woodpeckers! – I always enjoy hearing a woodpecker in the forest…and its a special tree to see them in our yard. The piliated, downy, and red-bellied woodpeckers are native to our area.

How to fight microplastic pollution with magnets – Many people filter their drinking water…but the conversation about filtering microplastics is newer. Hopefully filters that are effective and affordable will become the norm. It will take a long time to reduce the microplastic load already in the Earth’s water. We are just not recognizing the damage they are causing.

Americans Moving to Disaster-Prone Areas, Despite Climate Change – I’ve started to think about this more recently so appreciated seeing this post. Taking climate change into account – why would anyone buy property in areas that will be increasingly flood prone or incredibly hot/dry? A house nestled in a forest may look appealing but there are an increasing number of people that have already experienced the hazards of that beauty.

1,800-Year-Old Flower Bouquets Found in Tunnel Beneath Teotihuacán Pyramid – I visited Teotihuacan in the spring of 1966 when my parents took me to Mexico City. It was one of the highlights of the trip. The new discoveries are interesting….and I am thinking about whether I would like to see it again. Maybe in spring of 2026? The article references a site with some great pictures of Teotihuacan – worth a look.

Taking a Day off

/

What does ‘taking a day off’ mean when one is post-career? Next year it will be a decade since I left my career – my formal ‘work’ - behind. I’ve filled my days with a wide variety of activities that vary from day to day, season to season…evolving over the years. For some reason, I’ve been thinking about what is means now to ‘take a day off’ --- I still do it occasionally. There are some characteristics of those days:

  • I clear the day of other commitments. For example – I write my daily blog for the ‘day off’ ahead of time and post it so that it gets released at the appropriate time without anything more from me.

  • The day is filled with activities that are different than my normal…maybe it is spent traveling or in a special class or on a field trip…or maybe it is simply a pajama day at home, being lazy.

  • The normal daily goals I have for myself (books browsed, steps, Zentangle tiles, calorie limit, yoga time) become optional. I might still achieve some of them….but they are not required.

I don’t take a day off completely very often because I enjoy every day so much. There is no equivalent to the surge of activity that used to happen during my career that would exhaust me emotionally and physically…. necessitating a day off to recover. A partial day off does happen with some regularity because achieving some of the daily metrics takes enough time that I can’t achieve them all with the other unique activities of the day. There is so much to enjoy every day!

Zentangle® – August 2021

/

The August Zentangle tiles include some from the end of July – made after I had done the post a little early for the July tiles while I was still in Texas…and then making the road trip home. There are tiles made in Texas, Missouri, Kentucky and Maryland in this batch!

Making tiles is a calming activity before bedtime or while I am watching a burst of news. A variety of pens were used this month: Ultra Fine Sharpie Markers, Fine Sharpie Pens (new), various brands of gel pins (some with glitter…in Texas), Sakura Pigma Pen 05, and Sakura white Gelly Roll for highlighting.

It seems that doing something creative like making one or more tiles every day helps me be creative in other areas of my life. This month I’ve been breaking some of my dietary bad habits (dramatically reducing refined sugar and eliminating soft drinks) and tightening my personal actions re climate change. Those are significant changes for me….and require creativity for the actions I take to be as effective as possible.

Ten Little Celebrations – August 2021

/

So much to celebrate in August….

Drive through West Virginia. The beauty of the interstate in West Virginia (I64, I79, I68) that is part of my route from Springfield, Missouri to my home in Maryland is something to celebrate. It is full of curves, forests, mountains….and not a lot of traffic. It’s easy to enjoy as I drive.

IMG_5090.jpg

Cloud at sunset. Maybe it is being in the right place at the right time to see it that makes this a little celebration for me! This was taken from my office window.

Home again. I like to travel…but every time I do, I celebrate coming home. This time the delta variant ramped up while I was traveling and was relieved to get home…glad that my precautions on the road (vaccination last spring, masking, hand sanitizer, air purifier in hotel room, eating outdoors or in the car/hotel room) evidently worked.

Macro photography. My husband got me started with new gear and I’m improving although I am still at the stage of celebrating every in-focus image I get.

Stopping my diet Pepsi habit. I am celebrating more than 2 weeks free of my habit….still very consciously avoiding soft drinks completely!

Sunny day that was not overwhelmingly hot. We’ve had so many very hot days…that it was a treat to have one that was pleasant outdoors. My other strategy is to get some outdoor time before 8 AM before the day heats up.

Farmers Market. It’s fun to shop for veggies straight from the farm. In August, the cantaloupe, watermelon, tomatoes, and peppers were all tasty. The watermelons may be what I celebrate the most.

Zentangle tiles make on the deck in the early morning. A celebration pf creativity to start the day.

Spaghetti squash custard. Yum. I celebrated the flavor and texture of a simple custard.

Video of a Monarch butterfly emerging. Probably the high point of August for me. I’ve always wanted to capture the moment. And this time I did!

So much ice is melting that Earth’s crust is moving – When the weight of ice is removed, the land lifts upward…but new measurements show that it moves horizontally as well.

Top 25 birds of the week: Spiderhunters and Sunbirds! – Lots of colorful feathers in this group!

Pecan-enriched diet shown to reduce cholesterol – 470 calories per day is a lot of pecans more than ½ cup. I like pecans but will generally stick to about ¼ cup at a time…may skew toward eating pecans over other nuts although walnuts are a healthy choice as well.

California Drought Hits World’s Top Almond Producer – And maybe almonds are a nut that will be increasing in price…maybe driving people away from almond milk. I’ve already made my switch to lactose free milk.

Northern paper wasps recognize each others faces – Each face is unique!

Giant clams have a growth spurt – thanks to pollution – Evidently modern clams grow faster than ancient ones because of nitrates in the water. It doesn’t necessarily mean that are healthy…just that they are growing faster.

Photography In The National Parks: Fun Fact Photography, Part 2 – The post not only includes ‘fun facts’ about the National Parks – it also explains how the images were captured!

What happens to your brain when you give up sugar – A well timed article for me --- I am dramatically reducing refined sugars and artificial sweeteners in my diet (i.e., I still eat foods that are sweet like bananas).  I thought the headaches that occurred in the first week of my new diet were the simultaneous reduction in caffeine but maybe they were also caused by the sugar reduction.

Watch a bolt of lightning strike the Washington Monument – The monument is on a hill and the tallest thing around…..a conduit to the ground for lightning.

Nine things you should know about sea horses – The males give birth! Like many creatures right now – they are in trouble from climate change (and overfishing in some parts of the world). Not long ago – I learned that there is a species of seahorse native to the Chesapeake Bay. They live in sea grasses and estuaries…habitats that are in trouble.

Electric cars and batteries: how will the world produce enough? – One of the important steps that needs to ramp up as batteries (and solar cells) reach end of life – is recycling. We need to think about closed loops for the resources required to manufacture future renewables!

New analysis of landmark scurvy study leads to update on vitamin C needs – An example of the research behind how those ‘daily requirements’ of vitamins and minerals were developed. I wonder if more of the values need to go through a validation…how many would change just as the vitamin C requirement did.

Top 10 Grassland Species Across the Globe – The ones we have in the US are Long-billed Curlew, Black-footed Ferret, Pronghorn, Swift Fox, and American Bison.

The multi-billion dollar giants that are melting away – Glaciers. When they are gone…many parts of the world will be drier places. This article is primarily about central Asia…but the situation in South America is similar.

Loss of biodiversity in streams threatens vital biological process – Fungi and bacteria can’t do the decomposition job alone…the aquatic insects (often larvae) and crustaceans are needed too. And the populations and diversity of those organisms in our streams is declining.

Top 25 birds of the week: plumage! – Bird photographs…always colorful and interesting.

Gender revolutions in who holds the purse strings – The study was done in Britain…I wonder if similar (or different) changes are happening elsewhere in the world.

‘Polluter pays’ policy could speed up emission reductions and removal of atmospheric CO2 – A change that could speed up the transition we need to make…if we can somehow overcome the lobbying for the status quo trajectory.

Photography In The National Parks: Fun Fact Photography – This is a kind of photography you can do in lots of places. A little curiosity and a camera…some web searches…a neat cycle of learning/art that can turn again and again.
