25 Years, 25 Images – Celebrating twenty-five years since the launch of NASA Earth Observatory (EO) on April 29, 1999 and the EO website with a slideshow!

Insurance Companies: Consider Climate Risk Events As “Constant Threats” - Up until recently, most people weren’t concerned with how their ability to be insured would change — until catastrophic climate disasters began to wreak havoc on communities around the country. I am very glad I don’t own property in Florida or south Texas or California!

New Constitution Gardens (in Washington DC) Will Be a Biodiversity Mecca – Glad there are plans to improve the area. I always enjoyed it even though it was beginning to show its age in the 1990s and early 2000s when we lived in Maryland and visited with our young daughter.

Stunningly Preserved Ancient Roman Glassware Turns Up in a French Burial Site – Found during construction of a new housing development. I am always amazed at how durable a material we normally thing of as ‘breakable’ can be!

Cicada dual emergence brings chaos to the food chain - Cicada emergences can completely rewire a food web. For predators, these emergences are a huge boom in resources. It's basically like an all-you-can-eat buffet for the hungry predator. A study, published in 2023, found the emergence of periodical cicadas changes the diets of entire bird communities. Scientists have found that wild turkeys, for example, will capitalize on the bounty, leading to a wild turkey boom. However, caterpillars, usually preyed on by birds, were left off the dinner menu and their numbers more than doubled. This in turn led to damage to trees caused by out-of-check caterpillar populations. Rising temperatures will lead to periodical cicada emergences starting earlier in the year, experts believe, as well as an increase in unexpected, "oddly-timed" emergences.

Earlier Springs Cause Problems for Birds - As climate change warms our planet, causing spring to arrive weeks earlier than it has historically, birds are struggling to keep up. It’s not just the green vegetation they miss, but the pulse of protein-rich insects many bird species consume on both their breeding grounds and their migratory stop-over points. Birds will still breed but not quite as successfully because food will be more limited. Instead of chicks hatching as insect populations boom, those chicks may catch the end of the insect pulse.

Why you should let insects eat your plants – I skew the additions to my yard toward native plants….and let whatever insects show up enjoy. My community sprays for mosquitos so there probably is some reduction of other insects because of that. But there are enough left to support a barn swallow (and other insect eating birds) flock in our community.

Quantifying U.S. health impacts from gas stoves - Even in bedrooms far from kitchens, concentrations of nitrogen oxide frequently exceed health limits while stoves are on and for hours after burners and ovens are turned off. All the houses I’ve purchased as an adult, have had electric stoves/ovens except one and I only lived there for 3 years. But – in the 1950s and 1960s, my parents had gas stoves/ovens. Back then the houses were not as airtight as they are now so that might have reduced our exposure; my sisters and I never had asthma or other breathing problems, fortunately.

Inside the exquisite Tibetan monasteries salvaged from climate change – Built in the 1300s, the monasteries are impacted by a significant increase in the intensity of storms and rainfall across the region. Increased rainfall saturates the rammed-earth buildings, as moisture in the soil is drawn upward into the walls, leading to issues such as leaking roofs and rising damp. Local people have gained diverse skills, from reinforcing walls to crafting metal statues and restoring paintings. Over the past 20 years, a team of local Lobas trained by Western art conservationists have replaced the old, leaky roofs of the temples with round timbers, river stones, and local clay for waterproofing, and have restored the wall paintings, statues, sculpted pillars and the ceiling decorations, giving these centuries-old monuments a new life.

Possible Conch Shell Communication in Chaco Canyon Explored - The settlements of Chaco Canyon that spread around each sandstone great house fit into the sphere of sound produced by conch shell trumpet blasts; perhaps the settlements were designed to ensure that every resident could hear the notifications.

Gleanings of the Week Ending February 10, 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.

Sleep tight: A curious history of beds through the centuries – From 4,500 year old ‘beds’ at Skara Brae (Scottish island of Orkney…rectangular enclosures, around the length of a human…made from slabs of cold, hard stone…with tall headboards and raised sides) to Durrington Walls near Stonehenge (spectral outlines of long-vanished wooden bed boxes, where the builders of that monument may have once slept) to a clay figurine of a woman slumbering peacefully on her side, one hand under her head, on a simple raised platform to the gilded wooden bed in King Tut’s tomb (including a rigid, raised headrest rather than a soft pillow) to mats of dried leaves or animal skins to box beds to the ‘tick mattress’…hints of beds of the past.

Peru’s High-Altitude Hunter-Gatherers Ate Mostly Plants – Wild potatoes and the root vegetables made up 80% of their diet.

Rethinking Monarchs: Does the Beloved Butterfly Need Our Help? - The Xerces Society has published a joint statement signed by 10 top monarch biologists warning against the captive rearing and releasing of monarchs by backyard and commercial breeders. Such activities, they wrote, “promote crowding and disease spread.” The monarch is not in peril since the winter population in Mexico has shown no continued decline for the past 10 years. --- But there are some that still argue for continued ‘help.’

Deceptively Beautiful Invasive Plants – Avoid Lessor Celadine, Mimosa Tree, English Ivy…..Today, we have the opportunity to make gardening choices that benefit both the aesthetics of our gardens and local wildlife by removing invasive species and replacing them with beautiful and wildlife-friendly native alternatives. 

See the World Through the Eyes of Animals with These Stunning New Videos - To “see through” animal eyes, the team uses two cameras—one sensitive to ultraviolet light and one sensitive to visible light. Together, they capture light in four distinct wavelengths: blue, green, red and ultraviolet.

New genetic variants found in large Chinese mother–baby study - Mothers with higher blood pressure give birth to lighter and shorter babies than do mothers with lower blood pressure. This was just one of a multitude of links between maternal health and fetal development observed in a large genetic analysis of Chinese parents and their babies, which included some unexpected results. The researchers sequenced genetic data from blood samples taken from the parents and umbilical-cord blood of the infants and collected physical information about the mothers and their babies, including height and weight. The researchers identified discrepancies in the effect of some genetic variants on the same trait between mothers and their babies. For example, some variants were associated with altered cholesterol levels in infants but not in their mothers, and vice versa.

Preserving History at Bandelier National Monument – Two videos that show recreations of what the structures looked like in use based on archeological findings.

The 4-Second Nap: Unusual Sleep Habits of Animals - The killer whale, which can go a month or more without sleeping. Or the chinstrap penguin, which researchers recently discovered sleeps in four-second microbursts. Compare that to the koala, which conks out for most of the day.  When dolphins are sleeping with one hemisphere, one eye closes and one remains open. They sometimes rest motionless near the surface of the water or swim slowly, still able to breathe when needed. African elephants sleep for the least amount of time recorded of any land mammal.  The domestic horse sleeps just under three hours on average each day, and the domestic pony sleeps about three hours and 20 minutes. 

How a walk in nature restores attention - The study, conducted in 2022 between April and October, analyzed EEG data recorded on each of 92 participants immediately before and after they undertook a 40-minute walk. Half walked through Red Butte, the arboretum in the foothills just east of the University of Utah, and half through the nearby asphalt-laden medical campus. The participants that had walked in nature showed an improvement in their executive attention, whereas the urban walkers did not.

Climate change is causing a pothole plague. Are robots and self-healing pavement the solution? - In the United States, about 44 million drivers reported damage to their vehicles from potholes in 2022, which was a massive 57% increase over 2021, according to AAA. New developments offer hope for addressing potholes more effectively amid climate change, and are attracting investors….but innovations take time to be implemented.

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.

Two Baby Condors at Pinnacles National Park Are Healthy, ‘Adorable Fluffballs’ – Avian flu killed at least 20 California Condors in Arizona and Utah last spring…so the health of these birds is great news. So far, their lead levels (often a problem if their parents bring them carrion with bullet fragments) are low. They will make their first flights in October or November.

Biden Designates Baaj Nwaavjo I'tah Kukveni - Ancestral Footprints of the Grand Canyon National Monument – Protecting the land around Grand Canyon National Park.

Nearly Two-Thirds of All Species Live in the Ground, Scientists Estimate - Soils are richer in life than coral reefs or rainforest canopies, providing a home to nearly two-thirds of all species. The study is the first to tally the total number of soil dwellers, large and small, finding that more than twice as many species live in the ground as was previously thought: 59 percent of all species depend on soil for their survival, including 90 percent of fungi, 86 percent of plants, and 40 percent of bacteria.

Incredible Winners of Light Microscopy Awards Show Artistry of Scientific Imaging – The beauty of microscopic life….

Research Sheds Light on Steamboat Geyser’s Eruptions, Past and Present – They discovered that the strength of shaking decreased as snow depth increased. The ability of snow to absorb sound makes a difference!

Stunning Fields of Sunflowers Are Blanketing North Dakota – The states farmers grew 625,000 acres of sunflowers this year…and they bloom throughout August. Maybe one year we’ll make the trek to see them; I haven’t been to North Dakota before.

Exceptional Winners of the 2023 Nature inFocus Photography Awards – Beautiful…and educational. My favorite image is the ant with aphids (“A Sappy Alliance”).

What Pots Say—and Don’t Say—About People – “What can such a well-traveled artifact tell us about the people who left it in the ground? Its culture of origin may be less important than how it fit into life where it was found.”

Microplastics found in human heart tissues, both before and after surgical procedures - Everywhere scientists look for microplastics, they've found them -- food, water, air and some parts of the human body….even in the heart. But it still is not known how/if the microplastics impact the cardiovascular system.

Microalgae vs. Mercury - In the search for ways to fight methylmercury in global waterways, scientists at Oak Ridge National Laboratory discovered that some forms of phytoplankton are good at degrading the potent neurotoxin.

Avi Kwa Ame, Sacred Land in Nevada, to Be Preserved as a National Monument – Good! Another place to see when we make a trip in the west.

Volvo Delivers Its 1st Electric Heavy-Duty Truck in Africa – The truck is being used for collecting waste in Rabat, Morocco. Morocco is also home to the world’s biggest concentrated solar power facility.

A 90-year-old tortoise named Mr. Pickles just became a father of 3. It's a big 'dill' – Radiated tortoise native to Madagascar and critically endangered…at the Houston Zoo.

One of Europe’s last free-flowing rivers declared a National Park – Albania’s Vjosa River. Europe is also removing dams along other river just as we are in the US…but rivers that have been controlled by barriers will never be the way they were before the dam.

Clinics on wheels bring doctors and dentists to health care deserts – It’s a step forward and might work well for preventative or chronic care…but what happens in cases where the need is more urgent…like broken bones, having a baby, the aftermath of a car accident?

Technology over the long run: zoom out to see how dramatically the world can change within a lifetime – A graphic from ‘Our World in Data’ – worth the look. See the big developments they selected occuring during your lifetime….and when technologies we take for granted came along.

Take a Virtual Tour of the ‘Doomsday’ Seed Vault – Its doors are only opened a few times each year for new seed entries. The seeds come from countries from all over the world and are kept at -18 degrees Celsius. The most recent withdrawal was to re-establish a seedbank that had been destroyed in Aleppo during the Syrian Civil War.

Urban Trees Could Cut Summer Heat Deaths by a Third – Increasing tree cover to 30% could reduce premature deaths from urban heat islands by 40%. Sounds like a good idea of heath…and makes the cities more appealing too. Other actions can help too: green roofs/walls, light colored roofs/walls/landscape pavers, and replacing impervious surfaces with plants and soils.

Fresh produce contaminated with toxic BPA-like chemicals found in food labels – A Canadian study found that the chemicals migrate from labels in packaging materials into the food!

Common sweetener suppresses mouse immune system — in high doses – An artificial sweetener (sucralose) that might become a drug to reduce or replace immunosuppressive drugs that often have a lot of unpleasant side effects (if humans react to it the same as mice).

Fibromyalgia likely the result of autoimmune problems – Maybe this change in thinking (neurologic to immune system) will improve diagnosis and management of the disease.

How freezing changed the green pea – A little food history

Massive Antarctic Lake Vanishes in Just Three Days – A lot can be learned with observations from space…and once we see something interesting like this there is historical imagery that can provide a view from past years too.

Top 25 birds of the week: Bird Interactions! – Birds with others…of their own species and sometimes another bird species.

The Finalists of the Bird Photographer of the Year 2021 Are Announced – Just found this post that came out back in April…enjoy a double dose of bird photos in this gleanings list.

Photos of the Week – June 17, 2021 – Spider photos from The Prairie Ecologist

Fire Destroyed 10 Percent of World’s Giant Sequoias Last Year—Can They Survive Climate Change? – Very sad….and this year there could be more fires.

6 Surprising Tales of Predatory Birds – The 6 birds featured are: pelicans, great blue herons, turkeys, crows, kelp gulls, and vampire finches.

Coelacanths may live nearly a century, five times longer than researchers expected – An ancient form of fish that evidently lives a long time, reaches maturity at about 55 years old and gestates offspring for 5 years. This slow life history has implications for conservation of the fish. I also wondered how many other species we know only from fossils had slow life histories compared to organism we observe today.

Top 25 Birds of the week: Habitats! – Birds are everywhere (at least now/recent past). The decline in insect populations could make it problematic for many species to survive.

The Institutions of Extraterrestrial Liberty (Day 1: https://tinyurl.com/4t7zjv72 Day 2: https://tinyurl.com/2f9n4b72 Day 3: https://tinyurl.com/48rbba2k Day 4: https://tinyurl.com/5bbey7pr) – A series of webinars chaired by Charles Cockell (I enjoyed his astrobiology course on Coursera back in 2015 and his “Life in the Universe Pandemic Series’ back in Spring 2020). The subject in these webinars is freedom beyond Earth with talks on everything from liberty in Martian settlements to war in space. This is not about the search for life beyond Earth, but it is about the human future beyond Earth and how human societies might evolve over time. The schedule for each of the days is in the comments section so it is easy to select segments easily.

Gigantic flying pterosaurs had spoked vertebrae to support their 'ridiculously long' necks -- ScienceDaily – Their necks were longer than a giraffe’s…and the vertebrae had internal structure not seen in any other animal. The discovery was made with a CT scan and petrographic sections through the bone.  

Linking Birds, Farmer Attitudes and Conservation – The approach is not as straightforward as it might seem…there are nuances and feedback loops that need to be considered to get a positive result.

A breathtaking treasure reveals the power of the woman buried with it : Research Highlights – Early Bronze Age southeastern Spain…heavy silver diadem, silver ornaments…pots with intricate silver plating and daggers with silver-plated handles.

Challenging Conservation Not to Leave Women Behind – An example from the Solomon Islands….globally relevant.

100-Year-Old Lungs Yield Genetic Samples of 1918 Flu Viruses | The Scientist Magazine®- Lungs of 2 soldiers and a civilian preserved in formalin….from the first wave of the 1918 flu…when it was not as deadly as the later waves.

Why Peru is reviving a pre-Incan technology for water - BBC Future – One of the world’s first efforts to integrate nature into water management on a national scale. Projects include protecting high altitude cushion bogs and shoring up ancient water storage (routing water in the wet season to natural infiltration basins). These are ‘slow water’ solutions…mitigations that should be studied for other areas that are drying out as the climate changes.

An Estimated 50 Billion Birds Populate Earth, but Four Species Reign Supreme | Smart News | Smithsonian Magazine – And the 4 species are: house sparrow, European starling, ring-billed gull, and barn swallow.

How humanity has changed the food it eats - BBC Future – Perspectives on the processing of food through our history (and pre-history)…and where we are now. It is still possible to make choices that are healthy for us…but a lot of ultra-processed ‘foods’ readily available that are not.  

Hawai’i Island Festival of Birds

Wow – 5 days of the virtual Hawai’i Island Festival of Birds. Like the other virtual festivals we’ve seen….I want to go to the Hawai’i festival some year…the sooner the better! When we travelled to the big island in 2015, it was before we’d been to any birding festivals and I took only a few (poor) pictures of birds.

When we go back – I’ll be more prepared after having the experience of this virtual festival. My cameras (and photographic skills) are better than in 2015 too.

The sessions were pre-recorded and not as lengthy some of the other festivals. This was the only festival where native names and language (Hawaiian) were an integral part of the festival.

I listened to all the sessions…even the ones that were readings of books for children about Hawaiian birds….and I learned something from them all.

Day 1 was the longest because I also watch the two virtual field trip sessions:

  • An interview with the authors/photographer for the Field Guide to the Birds of Hawai’i…how it was put together and introducing a topic woven throughout the conference - the extinctions of native birds and actions to help the surviving species

  • Natural history and status of Hawaii’s seabirds….the impact of sea level rise on Midway Atoll where 91% of seabirds nest in Hawaii…and translocation projects to higher islands (islands within islands to keep mammalian predators out of nesting areas). Pacific Rim Conservation

  •  A Virtual Tour of Hakalau Forest National Wildlife Refuge…only place in Hawaii where native forest birds are stable and increasing…We’d get a guide or go with a tour group from the festival when we go. Birds are hard to see in the forest!

  • A Virtual Tour of Kaulana Manu Nature Trail … newly opened…off the saddle road on the big island. There is good signage and it’s something we could do on our own. There was a decontamination station for cleaning boots; there is a fungus that causes Rapid Ohi’a Death…a tree that many native birds depend on.

  • The status of eBird, Merlin, and Community Science in Hawaii….I need to remember to load Merlin’s Hawaii pack before we go!

  • Choosing the best binocular for You!...some binoculars have a short enough minimum focus distance that they can be used for butterfly watching; I quickly decided that, for me, I’d rather use my camera’s zoom to get close images of butterflies rather than watching them through binoculars. But – I did hear about Insect Shield Scarves…which might be something to have for warm weather birding!

Day 2:

  • Marvelous Moli…The albatross…The speaker wrote a book – Holy Moli….If we want to see them on nests we’ll have to go to Kauai. Maybe the festival will have a field trip for that.

  • Kolea…Pacific Golden Plover…learned a lot about how tagging has evolved over the years and how sophisticated tagging has shown how long and exact their migration is. The book by the speaker found here.

  • Hula and storytelling….listening and watching…like a meditation

  • Albatross of Kauai, the story of Kaloakulua…a particular Laysan Albratross from 2013/2014 season

Day 3:

  • Papahanaumokuakea Marine National Monument…a big place…not sure how we would ever be able to visit

  • Garbage guts…a children’s book about plastic garbage in the sea and a Laysan albatross

  • Tracking the endangered ‘Akiapola’au…with transmitters and receivers in the Pu’u maka’ala Natural Area Reserve. I remembered that my daughter and I walked around part of that reserve in 2015. I didn’t photograph any birds, but I did take one of my favorite pictures of the whole trip just as we left the fenced area heading back to the car – a camellia among tree fern fronds

2015 12 IMG_7720.jpg

Day 4:

  • Albatross…doing nest counts….they live very long lives (there is a female that was tagged in 1956 on Midway Atoll that is still producing healthy chicks there!)…World Albatross Day was June 19, 2020

  • A Perfect Day for an Albatross (book)… the author talked about producing the book and demonstrated her block print technique before the book was read by 2 educators at Kauai

  • Manu, the Boy who Loved Birds (book)…author talking with the publisher and the expert that helped with the book…and then a reading of the book…thinking about recent extinctions and what we can do to help surviving species in Hawaii

Day 5

  • Hawaii Wildlife Center…bird assistance/hospital and conservation programs…I learned that warm water is required if birds need to be washed because their normal temperature is higher than ours and if they are injured/oily/emaciated, they will go into shock if washed with room temperature water!

  • Manu-o-Ku (white tern) nesting in Honolulu…what happens when the chick falls out of the nest? Most of the time, volunteers are called and it’s put back in the nest or in the tree close to the nest…and the parents welcome it back!

  • No Ka Manu Hea Keia Nuku? (To which bird does this beak belong) (book) – In Hawaiian and about Hawaiian birds! It was a great finale to the Festival.

And after all the joy of the videos, I won a drawing for a festival swag pack that will be coming in the mail! The virtual festival was a great addition to our mid-October during this pandemic year!

Abstract Aerial Photos of Iceland's Rivers Look Like Watercolor Paintings – A little art photography to start out the gleanings this week.

Tomb Containing Three Generations of Warrior Women Unearthed in Russia | Smart News | Smithsonian Magazine – Evidently research is revealing that warrior women were the norm, not the exception, in Scythian culture. Scythians lived in small tribes, wore trousers (practical since they were on horseback much of the time) and fought with bows and arrows.

Protecting the Sonoran Pronghorn from Extinction – It’s complicated….lots of agencies involved….an international border that is becoming a migration barrier.

Is Notre-Dame Too Fragile to Be Saved? | Smart News | Smithsonian Magazine – Removing the scaffolding that was melted by the fire is evidently going to be a big challenge.

Whooping cough evolving into a superbug -- ScienceDaily – The research was done in Australia…but it probably applies to the US as well. Bottom line: we need to be developing an improved whooping cough vaccine.

One Reason Colorado Playgrounds Are Looking Way More ‘Natural’ | Colorado Public Radio – I like the new types of playgrounds….more than swing sets and slides…bringing in some natural elements.

White Sands National Monument Redesignated As A "National Park" – A beautiful and unique place. I’ve only been there once…but it was very memorable. The biggest surprise for me was that even on a hot day in June, the sand was not hot! Being white really does reflect the heat up and away.

2019 Year In Review: Some Great Photo Tips – So many beautiful places to photograph….take some time in a natural place (National Parks are awesome…but there are other places that are great too).

Striking Portraits of Rare and Endangered Birds by Tim Flach – I tend to like bird pictures from the wild…but these are amazing portraits. Virginia Cardinal – I was surprised to see it in this grouping…as far as I know they are not different than the Northern Cardinal. Cornell’s Allaboutbirds doesn’t have a listing for them.

Mealworms safely consume toxic additive-containing plastic -- ScienceDaily – Not an answer to the plastic problem…more like basic research that could be incorporated into a partial solution. The biggest gain comes from dramatically reducing single use plastics.

Earth at Night – This is an eBook from NASA that was last updated in December 2019….lots of pictures of the earth at night, analysis, and the technology behind the images.

Genomes Sequenced for Every US and Canada Butterfly | The Scientist Magazine® - Work by an evolutionary biologist at University of Texas Southwestern Medical Center. 845 butterfly species were studied.

Adding copper strengthens 3D-printed titanium -- ScienceDaily – Current titanium alloys used in 3D printing were prone to cracking and distortion. The copper alloy seems to overcome that problem.

When the best way to take notes is by hand - BBC Future – I like to take notes by hand….it always seemed easier to me than using a laptop (although I tried using a laptop to take notes in meetings during my career). Now it seems that it is better for internalizing concepts too. No need for me to try to change to anything else!

Blue Whales’ Hearts Can Beat Exceptionally Slowly | The Scientist Magazine® - As low as 2 times per minute! The high was 37 beats per minute.

Image of the Day: Ochre Paint | The Scientist Magazine® - Evidently ancient people heated aquatic bacteria mats growing in iron rich water to make a bright red paint which was used for rock art. The paint contains microfossils of the bacteria (Leptothrix ochracea). The red color is highly thermo-stable…something that has applicability to manufacturing.

Crows could be the smartest animal other than primates - BBC Future – Clever crows. Not so long ago we thought humans were the only ones to make and use tools.

Incredible Winners of the 2019 EPSON International PANO Awards – Panoramic photographs…a little eye candy for the week.

Trashed farmland could be a conservation treasure -- ScienceDaily – Interesting idea…but how much land is in this category and what happens to the people that are still trying to eke out an existence on that land.

Future For Silversword Plants At Halaeakalā National Park Dark – Rare plants…have not recovered as well as the Nene (Hawaiian goose) – for several reasons. Plants around the world are having to adjust to changing climate and some will not be able to change fast enough to continue to exist in the same places…some may become extinct. I hope the Silversword survives.

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.

Go Orchids: North American Orchid Conservation Center – A great site for learning about orchids…mentioned in my second post about the class I attended at the Smithsonian Environmental Research Center.

In praise of drawing - The Painters Keys – This is post originally written in 2006 but still very applicable today. I looked more at Internet Archive for some of the ‘how to draw’ books that were mentioned in the article; it’s amazing that in a 40-year period in the 1800s so many were published. A more recent post – from a science education perspective – was published in 2015: Rediscovering the forgotten benefits of drawing. I am contemplating taking a ‘next step’ from Zentangles to realistic drawings.

Time-Lapse Videos Capture Echinopsis Cacti in Bloom – Eye candy videos…beautiful.

Free Technology for Teachers: 7 TED-Ed Food Science Lessons – We could all learn a little more about the food we consume….educate ourselves to eat wisely.

Research Dollars Go Farther at Less-Prestigious Institutions: Study | The Scientist Magazine® - Interesting finding. I wonder if it will change how some organizations that award research dollars make decisions in the future.

Material formed from crab shells and trees could replace flexible plastic packaging -- ScienceDaily – This type of technology gives me hope. Recycling can’t do everything. We have to reduce the non-compostable materials in our packaging…have a net decrease in what has to be (expensively) recycled and/or go to the landfill.

Recovery: America’s Giant Squirrel Back from the Brink – Cool Green Science – I’ve seen signs about the Delmarva Fox Squirrel when we have gone to Blackwater National Wildlife Refuge but have never seen one. It’s good to hear a environmental improvement story!

As usual – I can’t resist the ’25 birds’ posts from National Geographic. Here are two that have come out recently: Top 25 Bird Interactions and Top 25: Wild Birds with Spectacular Catches

BBC - Future - The complicated truth about a cat’s purr – We all like to think that when our cat purrs that it is a sound of happiness…but is it?

Compound Interest - Volcanic eruptions: the chemistry of lava and volcanic gases and Compound Interest - The chemistry of spinach: the iron myth and ‘spinach teeth’ – Two posts from Andy Brunning. In the first one – click on the graphic and the larger version of the infographic will appear....a timely post with the volcanic event in Hawaii this summer.

Monitoring Conservation Easements

This December is my first experience volunteering to do the annual monitoring of conservation easements for the Howard County Conservancy. I went to a training back in September and then ‘shadowed’ an experienced monitor visiting 2 easements in November. In December, I was ready to monitor 2 easements with a cohort that was doing it for the first time as well.  The owners were notified by Howard County Conservancy that we would be monitoring on a particular day and the weather cooperated for both days – dry and not overly cold. The first property was mostly forest and the hike around the property was different than my usual hike since there were no well-defined trails; deer trails or picking a path through the briars (glad we were doing this in December when it was cold enough to wear heavy pants to protect my legs from thorns). It was a wonderful early winter ‘walk in the woods.’

The land was crossed by a stream that feeds into the Patuxent River. We had one stream crossing over a culvert but made another stepping on rocks; it was good that it had not rained recently. Most of the trees were native…but there was a substantial clump of bamboo growing on one streambank.

The land was easier to see with the leaves on the ground. As usual, I noticed fungi.

There was an odd holly-like plant as part of the understory. The leaves looked like holly but the top did not.

20171205_112732.jpg

At the end of the walk, I rejoiced that the property owner had made the effort to make it a conservation easement and that it was about that same as it had been in previous years.

The second easement was entirely different: surrounded by housing developments and an active farm/golf related business rather than forest. The business was about the same as it had been in the previous year…but there was a change at the farm: a guard dog. The dog did not appear immediately, but no one was home. We could tell that there had been some earth moving going on upslope from the stream that starts on the farm and eventually flows into the Patuxent River. If a heavy rain came – a lot of soil would slump down into the stream. The dog appeared…and we decided to gracefully retreat without completing our check of the easement. The monitoring will have to be done when the owner or their representative can be there. It was a rattling experience, but we enjoyed a hefty morning snack with hot tea/latte to recover!
