Gleanings of the Week Ending December 31, 2016

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.

Best of Mulitmedia 2016 – From The Scientist so most from the Life Sciences perspective. There is a display of infographics then links to the full stories. After that there are some videos. Quite a lot happened in 2016!

How to draw PACH – I am so pleased with this pattern. Remember the paper chains that children enjoy making with strips of construction paper? I remember making them…my daughter made them too. This is a Zentangle® pattern to draw them! It’s a lot easier than I thought it would be.

Happy Anniversary to Photo Ark! 10 Years, 6,300 Animals Photographed – The post is about Joel Sartore’s project to photograph the animals of Earth. Take a lot at the Photo Ark site as well!

Pregnancy leads to changes in the mother’s brain – I think most women acknowledge that there is a change…initially thinking it is just the effect of sleep-deprivation….and later realizing that part of the change is still there after the baby is sleeping through the night. For me – it not only helped me into motherhood, it also enhanced my ability to empathize with others. That made me a better manager and leader at work.

10,000-Year-Old Turf War – Even hunter-gatherers fought other groups of hunter-gatherers. I’m still following up on articles the students in the Osteoarcheology course on Coursera are finding.

Treasure Trove of Newly Discovered Species Includes a Newt that Looks Like a Klingon – My favorite is the first image (the Phuket horned tree agamid). Which one is yours?

“Celldance” Selections – 3 short cell biology videos: cell division, dendritic cell motion, and microscopy of living cells (within the body)

The strange effects of thinking healthy food is costlier – Evidently the health=expensive equation has a bigger impact on our perception (and purchasing) than objective evidence!

Phenology of Bee Genera: MidAtlantic States: USA – A slide show of graphs showing weekly counts for bees (by genus) in the area where I live from Sam Droege at the USGS Bee Lab….and links to other slideshows by the same author

Buying Experiences vs Buying Things – An infographic comparing spending choices (there is a link to expand the infographic…makes it readable). There are a lot of reasons that spending on experience adds to our happiness more than spending on things.

3 Free eBooks – December 2016

Scrapbook of Victorian Greeting Cards. Handwritten date of 1874. Available from Internet Archive here. I focused on the Christmas cards because – after all – it is December. Styles have changed considerably! This one of a child blowing soap bubbles – with a pipe held upside down…and, evidently, indoors – was one of my favorites.

Gordan, Elizabeth; Ray, John. Buddy Jim. New York: P.F. Volland Company. 1922. Available from Hathi Trust here. I looked at everything the Internet Archive and Hathi Trust had with John Rae illustrations. I liked this one because of its depiction of outdoor experiences of a child in the 1920s. How many children today spend this much time outdoors?

Wolle, Francis. Diatomacae of North America. Bethlehem, PA: The Comenius Press. 1894. Available from Hathi Trust here. The drawings in this volume – over 2300 of them – from over 100 years ago prompted me to think about a photography project this spring (diatoms) and some Zentangle patterns. It was quite a visual feast!

Gleanings of the Week Ending December 24, 2016

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.

Skeleton Lake of Roopkund, India – The lake is in the Himalayas and covered with ice for most of the year. Researchers think that the 200 people were killed by a sudden hail storm – with hailstones up to 9 inches in circumference.

Heading off Headaches – I am fortunate to not have headaches very often. When I look at some of the preventative steps listed in the article…most of them are part of the way I live all the time.

Skeleton found in Clare cave reveal a tragic life story – The skeleton found in a cave was analyzed and found to be a boy 14-16 years old at time of his death in mid-1600s. He had endured near starvation conditions for all his life. The space he was found in was just large enough to crawl into…and I wondered if he intentionally went to the cave to be alone when he died.

The Chemistry of LED Lights – We are seeing so many LED lights in Christmas displays. Here’s the tech details behind the brilliance.

Skin proteins reveal how mummies died – Three mummies analyzed. Based on the proteins found, one might have died of tuberculosis and another from pancreatic cancer. The third one had been interred in a hollowed out log and exposed to the elements over time; the proteins had degraded and could not be identified for that one.

An Unlikely Renaissance of Appalachian Elk – Outside Grundy, VA – in a former surface coal mine, now grass covered…a place for reintroducing elk to the east coast. There are places in Kentucky and Great Smoky Mountains National Park too!

Raw foodies: Europe’s earliest humans did not use fire – An analysis of dental plaque from 1,2 million old skeletons shows they were eating meat and plants….raw. There was no indication of charred fibers or of microcharcoal.

Top Technical Advances 2016 – From The Scientist Magazine – so skewed to biological sciences.

3D Skeletal System: 5 Awesome Ligaments – I am digging into anatomy after finished the Osteoarcheology class…and starting “Anatomy of the Abdomen and Pelvis”

The Challenge of defining maturity when the brain never stops changing – “The age of 18 doesn’t have any biological magic to it.” The concept of maturity links to responsibility for actions…an important concept in our legal system.

Gleanings of the Week Ending October 15, 2016

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.

Pumpkin steel-cut oats – I am collecting pumpkin (and other winter squash) recipes. They are probably my favorite seasonal foods. I am going to use some leftover butternut squash (already cooked) for one of them today!

Salt’s Secret Success in Ancient Chaco Canyon – Evidently the salts in the soil around Chaco Canyon are not chlorides …but sulfate salts which are not toxic to maize. And the sulfate salts are useful for making pigments too which were used to color walls and pottery. The research contends that the water management systems in Chaco Canyon did not cause catastrophic salt pollution and abandonment of the area as had been previously conjectured.

A Win for the Whooping Crane’s Texas Home – I have been thinking about making a winter trip to the wildlife refuges along the Gulf Coast of Texas – seeing whooping cranes being high on the priorities for the trip – so I notice articles like this!

Thirty Years of Progress – My undergraduate degree in biology was about 35 years ago so this series of articles is a good update for me.

The London Landmark with 20,000 Skeletons in its Vault – The Museum of London – and a project to examine 1,500 skeletons from the collection and compare them with skeletons outside of London. It will be a slice through history using a lot of the same technologies used in modern medicine.

Hummingbird Whisperer Captures Close-Up Photos of Birds Visiting her Backyard – Hurray for backyard photographer Tracy Johnson – patience and persistence!

Culling of White-Tailed Deer Coming to National Parks in Western Maryland – We don’t have any natural predators for deer….so culling has become necessary. In our neighborhood, all certainly just won’t last through the spring and early summer because the deer eat them, low branches of trees are nibbled (or eaten) – even the evergreens which must be very tough eating. There are way too many deer and in a suburban area like ours culling is not an option.

Antarctic Invertebrates – Many times we only think of the larger, more visible plants and animals of an area….but biodiversity goes way beyond that view. This article makes the case about why we should care about invertebrates in the Antarctic…not just the penguins.

A Bird’s Eye View of Simmering Kilauea Volcano at Hawai’i Volcanoes National Park – Last year at this time, we were planning a trip to Hawai’i in December and we enjoyed Volcanoes National Park when we went. Now I always take a look at any article about the place. This one includes a video of the Halemaʻumaʻu Crater now – even more active than when we were there.

A Sherlock-Worthy Look at an Ancient Horse Mummy – From the steppes of Mongolia and dating from the 6^th to 8^th century CE.

Blue Jays on the Move

Our neighborhood has a troupe of resident blue jays that make their rounds – most days – through our backyard for the bird bath and swooping off to the maple and then the taller tulip poplars at the edge of the forest. Sometimes they stop to look through our gutters for bugs in the leaf debris. The picture below is one on our deck railing after he got his drink of water. That is the small part of the route that they are easy to see; some of the time I miss seeing them completely but I always hear them.

This time of year the numbers of blue jays are much higher because so many of them are migrating through Maryland to go further south for the winter. I’ve often wondered whether the resident ones ‘talk’ to the transient birds because it seems like we have more blue jays around than we have during the rest of the year.

While I was raking leaves on Wednesday (the first round of the chore for this year!), a flock of blue jays chattered (or is it more like arguing) in the trees above.

Goldfinches in the Fall

In late September, I was lucky enough to get some pictures of male goldfinches visiting my deck – for the flower seeds and birdbath. At first they looked like a slightly duller version of their normal selves.

As I looked closer at one feeding on zinnia seeds – I noticed that the feathers were in the process of changing over to winter plumage which is not the bright yellow that they have in summer. The new colors will help the birds avoid predation in the winter.

The change was even easier to see in this series of image of a goldfinch at the birdbath.

Soon the yellow feather will be gone – and there will be a brown-black-white bird that will stay around our feeders (as soon as I put seed in them again). I’ll have to develop more skill to recognize them!

Chipmunk in the Garden

A week or so ago, before my new camera arrived, I was out taking pictures of insects in the garden are at the front of my house. I heard rustling in the bushes. I wondered if it was the lizard I had seen on my front porch. More rustling. I decided it was something a little bigger than the lizard. I continued taking pictures and listening to the sounds of the front flower bed. Then I looked down at the tubing we attached to the outlet from our sump pump to drain the water further away from the house ---- a chipmunk was staring up at me. The zoomed setting was perfect for getting a quick picture!

Now that I think about it – I wonder if the tubing is still attached to the sump pump. It seems to be a highway for the chipmunk these days so there must be an opening on an end close to the house where the animal enters the tube.

3 Free eBooks – September 2016

So many good books….so little time. Here are my picks from my September online reading.

Reeves, William Pember; Wright F. and W. (painters). New Zealand. London: A. and C. Black. 1908. Available from Internet Archive here. The illustrations are wonderful….a rendering of what the country was like before the first world war.  The pictures of landscapes and natural areas encourage thinking about exploring there (hoping that those places still exist).

Johns, Thomas Rymer. Cassell’s Book of Birds. London: Cassell, Petter, and Galpin. 1869. Available on Internet Archive here. This books includes illustrations of Birds of Paradise. We still see them as amazing birds with improbable feathers. Think what a sensation they must have been when this book was published in the mid-1800s.

Rackman, Bernard, Read, Herbert Edward; Glaisher, James Whitbread Lee; English Pottery – its development from early times to the end of the eighteenth century. London: Ernest Benn, Limited. 1924.  Available on the Internet Archive here. Lots of good ideas for Zentangle patterns in this book! I am noticing that copyrights are expiring on books all the time and topics I have explored before on the Internet Archive have new books available. This was one example.

Hummingbird Moth at Brookside

I was thrilled to see a hummingbird moth enjoying the flowers at Brookside Gardens last week. The insect is always one I look for during the mid to late summer in the fragrance garden since that is where I’d seen one before. They are probably their every year but I have not seen then consistently so it was a special treat to see it and photograph it too. The images are good enough to identify it as a snowberry clearwing hummingbird moth (Hemaris diffinis) (Info from USDA and Wikipedia).

The wings have red veins but are almost always moving so fast that they are blurred or can’t be seen at all. The insect moves rapidly from flower to flower – similar to the way a hummingbird moves. I watched this one in two stretches. (Interrupted by a group of women with strollers in the garden for a ‘new mother’ outing; they need the full path and I stepped out of the way…remembering fondly that time of my life that is now more than 25 years ago).

I took lots of pictures, trying to get every angle and proboscis position. Look for the following in the slideshow below:

• A skipper butterfly photobomb
• Extended proboscis
• Fully extended wings – with a flower send through the ‘clear’ wing
• Coiled proboscis
• Antennae structure
• Bristles on the end of the abdomen
• Fuzziness of the thorax

Some Birds at Centennial

My short walk at  Centennial Park last week included several bird sightings. I was most excited about a green heron that flew into a tree not far from where I was walking. I didn’t know what it was until I managed to zoom in enough with my camera. It is surprising how well camouflaged the birds are in the foliage. It flew down to the water’s edge from the tree and I didn’t see it again until it flew away across the water.

There was a mourning dove enjoying the morning sun on a park bench. When I walked closer it flew down to the shore…then squeakily away to the island in the lake.

There were birds in some foliage near the shore with berries. One flew out and perched on the top of a sign. I think it was a mockingbird. It proceeded to fluff its feathers – looking rather comical as it preened.

Way across the lake – a great white egret was fishing in the shallows. This picture is about at the limit for the zoom on my camera but I like to take pictures of these graceful birds. There were two great blue herons that flew low over the lake while I was there…but I wasn’t fast enough to get a picture of either one.

Almost Hidden

Sometimes I take pictures and capture something unexpected – like the katydid in a day lily taken back in July.

Or the tiny spider in a black eyed susan (during the ‘Black Eyed Susans in the Morning’ photo shoot).

Sometimes I take the picture knowing that there is something more – like this tiger swallowtail almost hidden behind a sunflower. I had been taking pictures of the butterfly on the zinnias just beforehand…and decided to do the hide and seek picture just to be different.

And then there are the milkweed bugs that are hiding on just about every milkweed seed pod I find – but they are rarely positioned to be completely visible!

Lizard on the Front Porch

I see lizards more frequently when I travel (to Hawaii, to Texas, to Arizona) than I do at home. So I was pleasantly surprised to see one on my front porch a few days ago. It was in the later afternoon on a warm day – not overwhelming hot.

It appears to be an American five-lined skink, one of the most common lizards in Maryland – although its tail does not look particularly blue. It stuck around long enough for me to take a few pictures through the long narrow window beside the front door.

It another good indicator of the overall health of the habitat around the immediate vicinity of my house!

Microphotography from the 1970s

I found some microphotos from the 1970s when I was scanning some old slides and prints. The first set is algae from my last year of high school. It was a new school and the microscopes were new too. My boyfriend (a year later he became my husband) was the one with the camera and he had an adaptor to attach the camera to the microscope. The color images did not turn out as well as I wanted – the lamp was not bright enough or the film was not fast enough to make the background as white as it looked to the eye and the greens did not stand out. Still you can see the spirals of the spirogyra. I had collected samples from streams near where I lived; in one case the filamentous algae were growing on a rusting sewing machine that someone had dumped in the water (the algae had picked up the rusty color too).

The black and white image was actually better although some of the filaments look battered.

Several years later, I was taking a mycology class and had slides from various kinds of cultures fungus spore structures. We evidently didn’t bother with color slides although I wish now that we had since the dye used was a very nice blue.

Of course, all was film during that time period. There was a time lag between taking pictures and finding out if they were any good and it was relatively expensive. I’m glad we made the effort and managed the expenses. But it also increases my appreciation of digital photography!

More Dragonflies (at Kenilworth Gardens)

I posted some dragonfly pictures from Kenilworth Park and Aquatic Gardens earlier in the month but then we made more visits to the place and I got some even better pictures by zooming in even more (and using a monopod to stabilize the camera). It is easier to see wing damage (lower left wing) and how the wings attach to the insect.

Their heads and legs have more bristles than I expected…and there is a ‘face.’

The eyes bulge out – dominating the head. The wings have an intricate pattern of supports for the wing membrane and the wings are not exactly flat.

The different kinds of dragonflies have a different pattern of wing structures.

The opening in the mid-back where the wings are attached looks so alien - or not the smoothed structure of other things like fly (butterflies, birds, or airplanes).

Enjoy the slide show below of more dragonflies!

Photographs through a Window – July 2016

I stopped putting birdseed in our feeder in early July when one of the squirrels got coordinated enough to dump a little seed from it. It wasn’t happening consistently so the ‘squirrel proof’ was not filing totally but enough that I decided they didn’t need the extra food in the summer months. I still go quite a few birds to photograph through my office window. The parent of the juvenile house finches featured in yesterday’s post must have been the birds I saw most frequently around our deck.

This frazzled looking Carolina Wren might be a fledgling from the nest in an old gas grill.

Nuthatches always look alert when they are in their head-down stance. This one was enjoying the last seed I put in the feeder.

There is a male indigo bunting that I see periodically so it might be nesting nearby. I photographed the bird from my office window

Then went downstairs to get a different perspective through the French door in our breakfast area. The mourning dove provides a nice size contrast.

The juvenile cardinal still had some downy looking feathers on its breast and around its head

But its bill has turned the adult color over the past month.

I am keeping our bird bath full of fresh water so I expect that will be the reason birds will continue to visit our deck for the rest of the summer.

The bird on the right is making motions like a chick begging for food – but the one on the left does not look like they will be obliging!

Green Heron at Kenilworth Gardens

Last weekend when we went to Kenilworth Park and Aquatic Gardens, I decided to walk out to the boardwalk rather than stay in the area around the lotus and water lily ponds --- and I found the high point of the visit in the wetlands beside the boardwalk. Not far from the boardwalk, on a partially submerged fallen tree, was a green heron fishing for breakfast.

When I first saw the bird there was another nearby that flew away…but this one stayed long enough for me to move around to get some of the twigs out of my line of sight to the bird.

I zoomed out to get more of the scene. The bird was catching tiny fish – moving so quickly that I didn’t quite capture an image of the fish before it was swallowed.

The bird moved and my line of sight was even better.

The bird is only about as big as a large robin but has much heavier legs and feet...and a longer beak.

And it even posed for a maximum zoomed portrait!

Kenilworth Water Lilies

The two dominate plants at Kenilworth Park and Aquatic Gardens during June and July are the water lilies and the lotuses. The sign for the visitor center has a water lily design. The flowers rest at almost the same level as the leaves very near the water surface while the lotuses are above the water – the leaves being a layer that flutters below the flowers that are higher still. I like photographing water lilies – particularly ones that have a lot of color and the background is dark enough to set off the color.

I always wonder what causes the plants to grow only in part of a pond. Perhaps it has to do with water depth.

During our visit in late June there were quite a few geese in one of the ponds that was filled completely with water lilies. They moved through the heavy foliage. They just swim through the foliage and the plants close behind the big birds. I zoomed in (series below) to get a closer look at the geese and noticed that some were juveniles – just beginning to get their adult markings.

As usual – I looked particularly to find flowers that be being visited by bees. Do you think these two bees are the same kind of bee? The lighting makes it hard to tell.

Dragonflies at Kenilworth Gardens

Kenilworth Park and Aquatic Gardens in June and July is my favorite place to practice photographing dragonflies. We’ve been twice so far this year and seen at least three different kinds. There are the ones that are powder blue with green eyes – their wings almost clear.

There are darker ones – that look almost black….and their eyes are glossy black.

Last but not least, are the ones with black and white markings on their wings. There were not as many specimens of this particular kind so I only got two pictures.

All of the swoop among the lotus flowers and buds – alighting long enough for photographers. I captured all the above pictures with my Canon PowerShot SX710 HS…. attached to a monopod. I wanted to capture some of them dragging their abdomens in the water laying eggs…but didn’t see any so far. There were some that were defending territory; there was some noisy mid-air collisions!

Brookside Gardens’ Wings of Fancy

Brookside Gardens’ annual butterfly and caterpillar exhibit is going on now - continuing until September 25th. It’s best to go as early as possible since the conservatory where the exhibit is housed is about 10 degrees warmer than the outdoors. It if gets above 100 in the conservatory, they often close the exhibit; the butterflied like the heat but people wilt quickly in the heat and humidity.

The caterpillar part of the exhibit is an entry way before the main exhibit. A volunteer is there to explain the exhibit and point out the caterpillars on the food plants. Can you find the cecropia moth caterpillar in the image below?

If not – I’ve circled it in this thumbnail.

Right after I entered the butterfly exhibit – a blue morpho settled for a bit on one of the walls. Usually they do not sit for long with their winds open like this so I felt lucky to get the picture right away. This one looked very battered – probably near the end of a relatively short life cycle of about 115 days.

The day was warm enough for all the butterflies to be active and one of them settled on my T-shirt; I got a picture before it flew off.

But it came back and landed on the hat I’d tied to the strap of my bag.

Another butterfly liked the back of my pants.

Enjoy the slide show of my photo picks from the rest of my walk around the conservatory. I’ll be going again every time we have guests from out of town this summer!

Wallops and Chincoteague in 1978

I’ve been scanning our collection of old slides and will be posting about some of my ‘finds.’  This post is about the first exposure to Chincoteague and Wallops Island. My husband – in the early days of grad school – went on a research trip there in May of 1978 and stayed at the Refuge Inn (still our favorite place to stay). The picture of the pony corral from an upper floor of the Inn looks about the same – dated only by the cars in the parking lot.

Growing up in north Texas – the ocean scenes were new to him. The research was a collaborative effort with the Russians and they were based on a research vessel off the coast which added to the experiences. One trip out to the Russian vessel resulting in my husband’s camera getting sprayed with salt water; it never recovered fully and he started his collection of Canon cameras with the following year.

Pictures of nature are relatively timeless. There are still egrets, water, and grasses,

Gulls (and unfortunately discarded tires),

And my husband and I still try to photograph the birds in flight. He succeeded with an egret in 1978! I was surprised that there were no pictures of Great Blue Herons from 1978. Did he just not notice them….or were there not as many as there are now?

The lighthouse still shows up above the trees although the trees seem higher now.

There are still a lot of radio dishes at Wallops island that can be seen from the road.

Since he was actually on the facility, he got closer views.

He travelled with a lot of instruments. He checked a lot of equipment. He was assigned a small vacant observatory for his set up for the week. This pile was what it looked like after he packed it all back up to come home. I suppose some of the briefcases and luggage date this picture too! The plaid suitcase was one that had been collapsed on the trip up but contained laundry and seashells collected on the Wallops Island beach for the trip home!

The last to be packed: the insect repellent (he still remembers the salt water mosquitoes vividly) and his sunglasses. The packaging for OFF has a familiar look!
