Review of Tales from the Ant World, by Edward O. Wilson

Reviewed by Don Coram

Edward O. Wilson is perhaps the most famous living naturalist.  He has written more than 30 books on nature, two of which have won Pulitzer Prizes.  He is one of the naturalists mentioned in the FMN Basic Course.  

In this book, Wilson describes the fascinating diversity among the 15,000 (known) species of ants (probably twice that number overall).  The study of ants is called myrmecology.  Ants have been around for 150 million years.  Adaptive radiation, in which a few successful ant species multiply dramatically into many species filling specialized niches, started in the Mesozoic era and led to the diversity that we can observe now.   

Wilson describes the characteristics of a variety ant species, including their physiology, behavior, personalities, and social organization.  His list includes common kitchen ants, carpenter ants, fire ants, army ants, leaf cutter ants, and bull ants.  Ants are the most warlike of all animals and the book describes some of the fiercest ones.  But there are also timid ants who disappear when threatened, only to reform the colony quickly when safe. And the society of leaf cutter ants is surprisingly complex.  You must read the book to learn about other astounding adaptations in ant species.

For us amateur naturalists, the book describes Wilson’s life-long interest in ants and nature in general.  As an 8-year-old boy, he began collecting and identifying insects in his backyard.  Between the ages of 10 and 12, he lived in Washington DC, near the National Zoo and Rock Creek Park, which were inspiring to him.  By 13, his family had moved to Mobile, Alabama, where he continued observing nature and soon found a colony of invasive fire ants.  His was the first record of these ants in the Northern Hemisphere, and they came to be a serious pest in the South.  The book continues describing Wilson’s field trips over the next 8 decades seeking ants throughout the world.  He finds them atop mountains, in deserts, on isolated islands, and in caves.  The book also describes how Wilson learned to communicate with ants.  He was able to extract and purify a fire ant pheromone and use it to communicate with ants to direct them to follow a particular human-selected trail.   Wilson is a now professor-emeritus at Harvard University.

Spruce Up your Foundation Plantings

Photo and article by Plant NOVA Natives

When developers build a neighborhood, they almost always add some shrubs against the foundations of the houses to soften the lines of the buildings. Just as they paint all the interior walls white, they use just a few conventional plant species for a uniform look until all the houses are sold.  The new owners get used to the look and never bother to change it. But the foundation planting area offers a big opportunity to beautify the landscaping, eliminate the need for pruning and help support our local birds and butterflies at the same time.
 
Native shrubs constitute an essential middle layer of the ecosystem, providing food and shelter for songbirds. Providing this layer in our yards is even more important in areas where the deer have eradicated native shrubs in the woods. Unfortunately, at the time when most of our houses were built, the importance of using native plants was not known to the builders, and so most of the commonly used plants are species that were introduced from other continents. Not only do they not provide food for wildlife, many of them have escaped into nearby natural areas, where they proceed to destroy the ecosystem there. Examples of that include Nandina (also problematic because its red berries are poisonous to Cedar Waxwings), Japanese Barberry (also problematic because it harbors ticks), Privet, Burning Bush, Leatherleaf Mahonia, Double-file and Linden Viburnum, and several species of Bush Honeysuckle.
 
Luckily, there are many non-invasive alternatives. Best of all, many of these are native plants and therefore support the birds and butterflies with which they evolved. These plants have become increasingly available at our local garden centers. For the area under a window, it makes sense to choose one whose ultimate height when full grown will not block the view, thus making pruning unnecessary and allowing the plant to assume its own graceful shape. Many have beautiful spring flowers; others have striking red berries that provide interest well into winter.
 
Of course, most people don’t know the names of the shrubs in their yards. This can be figured out by using a plant ID app such as Seek or iNaturalist. Residents can also get a free visit from an Audubon-at-Home volunteer to help identify invasive plants and strategize about alternatives.
 
Shrubs are not the only plants that are suitable for foundations. Small trees where there is room, native ornamental grasses in the sun and native ferns in the shade are all natural choices. For those who like the conventional look that came with the house, there are plenty of native shrubs that can achieve the same aesthetic. Other people might want to add character to their yard by choosing something a little different.  And rather than planting annuals every spring, why not plant a few native perennials just once to get that pop of color year after year? For more details, see the shrubs page and the foundation planting page on the Plant NOVA Natives website.
 

United Nations Sustainable Development Goals

The 2030 Agenda for Sustainable Development, adopted by all United Nations Member States in 2015, provides a shared blueprint for peace and prosperity for people and the planet, now and into the future. At its heart are the 17 Sustainable Development Goals (SDGs), which are an urgent call for action by all countries – developed and developing – in a global partnership. They recognize that ending poverty and other deprivations must go hand-in-hand with strategies that improve health and education, reduce inequality, and spur economic growth – all while tackling climate change and working to preserve our oceans and forests.

Find the list, ways to engage, and lots of resources here.

The UN asked musician AY Young to be its only US ambassador on behalf of the 17 SDGs–because he powers all of his concerts with renewable energy.

Review of Naming Nature, by Carol Kaesuk Yoon

Reviewed by Michael Reinemer

In the midst of an accelerating mass extinction where we are losing species much faster than science can identify them, this is an engrossing look at taxonomy, or how we organize life on earth.

Yoon laments our disconnects from nature. A child living among the Indigenous Tzeltal Maya people in Mexico can identify about 100 different plant species, Yoon says. How many American adults can do that?

She provides an account of “folk” taxonomies that are binominal, two-word descriptors the predate Carl Linnaeus, the botanical whiz kid from Sweden who published Systema Naturae in 1735. That system laid out the framework that most of us learned, the Linnaean hierarchy — kingdom, phylum, class, order, family, genus, species. (Of course, we use that every time we select an unadulterated native plant for our garden, relying on the scientific name — genus and species — rather than a vague or even misleading common or commercial name. Don’t we?)

Later schools of thought refined how we might arrange living things. Well into the 20th century, “cladists” organized the tree of life around the branches (clades) based on evolutionary relationships. They famously declared that, technically, fish don’t exist. Lungfish, they would explain, are more closely related to cows than they are to salmon. That news would have been nonsensical to Linnaeus, and perhaps blasphemous to Izaak Walton. Walton described his 17th century meditation on conservation, The Compleat Angler, as a “Discourse of Fish and Fishing.” In any case, the cladists’ fish-dissing were fightin’ words to other taxonomists. With breezy, engaging insights, Yoon chronicles the debates.

Winter is for Nature Lovers

Article and photos by Barbara J. Saffir (c)

Don’t hibernate! Winter is for nature lovers.

You can glimpse Bald Eagles nesting, self-heated skunk cabbage wildflowers that resemble Georgia O’Keefe paintings, perky kinglets that pop up their ruby-red crests when they’re excited, sly foxes hunting for a mate, and many other winter wonders mentioned below. It’s enough to transform winter loathers into winter lovers.

Ruby-crowned Kinglet

But before heading out on frosty trails, it’s important to gear up and to prepare so you truly have fun and stay safe rather than just enduring an uncomfortable walk.

Bring water, a snack, and a fully charged cell phone. Watch the radar with your own eyes and consult two different weather apps. Tell someone where you’re going. Dress for 20° colder than it is, especially if you’ll be standing around for more than 60 seconds. Wear layers. Feel fireplace-warm with a scarf, a hat, gloves, ear muffs, wool socks, and hand/toe warmers.  If it’s snowy, icy, or soggy wet, clip Yaktrax or similar cleats onto your waterproof shoes or consider Gore-tex boots or spiked trail-running shoes to stay warm and to prevent falling. Or grab your snowshoes or cross-country skis to discover more of winter’s treasures. 

There are also a slew of other benefits to winter treks, such as a shot of long-lasting energy, stronger muscles and bones, better cardiovascular health, and an uplifted soul.

Whose soul would not be inspired by watching colorful “snowbirds” that choose to winter in Virginia instead of Costa Rica, greenery that paints khaki forests with cheer, and Instagram-worthy views of landscapes and critters that are usually hidden by a tangled thicket of trees and shrubs? And did I mention that (virtually all) snakes and ticks are “sleeping”?

Yellow-bellied Sapsucker


Some of my favorite winter birds are Yellow-bellied Sapsuckers (no, it’s not a cartoon character), White-throated Sparrows (they sometimes sound like computers), Ruby-crowned Kinglets and Golden-crowned Kinglets (my latest infatuation), Red-breasted Nuthatches (2021 is an irruption year), and Dark-eyed Juncos (I once saw a leucistic one). I also adore photographing wintering waterfowl like Canvasback ducks with rusty red heads and bright red “vampire” eyes, elegant “super-model” Tundra Swans, chunky “boy-next-door” Snow Geese, and feisty American Wigeon ducks with green-striped heads and squeaky voices.

You can pinpoint these birds’ locations with the free eBird app and it can alert you to rarer visitors, like teensy but tough Rufous Hummingbirds.  (One is visiting the Beatrix-Farrand designed Green Spring Gardens as of late December, 2020.) Free Merlin, Audubon, and other birding apps can help you identify your finds with photos, bird songs, territory maps, and more. 

Red fox

You’ll know you’ve stumbled upon a sapsucker if you hear meow-like sounds and spot trees with perfect rows of square holes.  Itsy-bitsy Golden-crowned Kinglets might flit down beside you to show off their sunflower-yellow crests.  These and many other birds hang out in forests or at the forest edge, especially if it bumps into a meadow.  It doesn’t hurt if there’s a creek, a waterfall, a bird bath, or another water source nearby. In Northern Virginia and throughout the DMV, you’re never more than a mile from a “birdy” park or other public land. Winter ducks even promenade around the pond at Constitution Gardens near the U.S. Capitol.  Red foxes also live on the National Mall, parading around at dawn and dusk before joggers and tourists scare them away. Red foxes are probably prowling through your own backyard or neighborhood park in the winter since it’s their breeding season.

Juvenile Great Horned Owl

And don’t forget our common birds like fire-engine red Northern Cardinals (one of the most beautiful birds on the planet) that you can often see better without leaves obscuring your views. The more you notice about them, the more likely you’ll fall in love.  Relatively common birds like Bald Eagles and owls nest in the winter.  Depending on the weather, Virginia’s Great Horned owlets typically hatch in the winter. Fuzzy eaglets greet the world a tad later: by late winter or early spring.  But if you’re lucky, you might catch Ma and Pa Eagle adding new sticks to their massive nests in early winter and sitting on their eggs by February.  Both of these big nesters live along the Potomac River in Arlington near Spout Run. Another eagles’ nest flanks the main trail through the Dyke Marsh Wildlife Preserve. To find dozens of others in Northern Virginia, consult the Center for Conservation Biology’s unparalleled eagle nest map. Just don’t venture closer than 330 feet to an active nest or the feds might swoop in to bust you for breaking the law since eagles are still protected.  

At Dyke Marsh, you might also see Barred Owls “honeymooning” this winter.  Babies come a bit later. This popular peninsula on the Potomac River attracts a great variety of birds year-round.

Huntley Meadows Park is another “must see” bird hangout.  Cute Brown Creepers with two-toned curved beaks zip head first down the frigid tree trunks while Northern Pintail ducks dabble for dinner along the boardwalk of this locally famous wetland. If you’re extra lucky, you might spy a common muskrat chomping on its leafy green dinner. In late February and early March, woodcocks perform spiral “sky dances” to lure mates.

Muskrat

Some parks, like Ellanor C. Lawrence Park, hang bird feeders, which makes it even easier to gawk at beautiful birds close-up.   But you don’t have to visit those hotspots for a bevy of birds. Just trek anywhere along Fairfax County’s 40+ mile Cross County Trail and NOVA Park’s 45-mile W&OD Trail to find these treasures.  Before you go, open Fairfax County’s comprehensive “Trail Buddy” trail map in the free ArcGIS Explorer app and you’re all set.  With that in your pocket, try going on an adventure alone one day.  You’ll likely find more birds and critters.  Or if you’re in a group, stop often to listen for sounds of life.  

Wherever you go, you might encounter rascally raccoons, acrobatic eastern gray squirrels (and maybe some black morphs), white-tailed deer, and perhaps even a Virginia opossum, North America’s sole marsupial.  Salamanders and green treefrogs also stick around in the winter. Sometimes they’re no farther away than underneath a flat log or a hefty rock.  It’s best to leave them slumbering. (Unless you’re conducting an iNaturalist bioblitz!) But thumb-nail sized spring peeper frogs will announce where they are in late winter with their deafening, high-pitched wailing.

Virginia’s forests are dotted with green life all winter long. Clumps of American mistletoe are visible near the treetops. The white berries of this parasitic plant are poisonous for humans but a yummy snack for Cedar Waxwings and other crayon-colored birds.  

Lush Christmas ferns paint the forests a deep green hue.  Light-green, yellow-green, and gray-green lichens light up trees and rocks. Bog clubmosses form a spongy green oasis on the ground. Invasive plants, such as English ivy, wind their way up trees. They’re not good for the health of the trees, but birds and critters find them a warm and welcoming hideout. Pint-size partridge-berry plants (the Virginia Native Plant Society’s “Wildflower of the Year” in 2012) and spotted wintergreen plants also decorate the dirt.  The leaves of August-blooming Cranefly orchids stand out. They are green on top and plum-colored underneath.

Native and non-native flowers, berries, and seeds also brighten the winter woods. You can find little white snow drops spreading along the ground; sunshine-yellow leatherleaf mahonia and winter jasmine; spiky apricot-colored and pale yellow witch hazel flowers; and ivory and pink hellebores; along with brick-red sumac seeds, beaming American red holly berries; and glowing red winter holly berries.

And all those eye-candy seeds and berries must taste like real candy to critters and birds. Maybe they like them so much that it has transformed them from winter loathers into winter lovers.

American Energy Innovation: The Federal Policy Landscape

This Zoom Webinar was held on Dec. 14, 2020, noon-1 pm

Here is a recording of the session.

Decarbonizing the US economy will require substantial investment in research, development, and deployment of technologies that have not yet entered the marketplace at large scale. There is bipartisan support for federal policy to support such clean energy innovation—particularly under the auspices of the American Energy Innovation Act, a multi-billion-dollar piece of legislation currently under consideration in the US Senate. (A companion bill, the Clean Energy and Jobs Innovation Act, was passed by the US House of Representatives in September 2020.)

Join Resources for the Future (RFF) at this important moment for innovation policy as they host a conversation, “American Energy Innovation: The Federal Policy Landscape.” Their distinguished set of panelists—including one of the lead architects of the American Energy Innovation Act—will discuss what parts of the innovation ecosystem policy can most readily support; how past innovation policies in the United States have fared, both in the energy sector and elsewhere; how the private sector takes signals from policies; and how the discussion around energy innovation policy has unfolded on Capitol Hill over the past year.

Speakers

  • Colin Cunliff, Information Technology and Innovation Foundation
  • Spencer Nelson, Senate Committee on Energy and Natural Resources
  • Richard G. Newell, Resources for the Future
  • Kristin Hayes, Resources for the Future (moderator)

Additional speakers to be announced.

About the Advanced Energy Technologies Project

RFF’s Advanced Energy Technologies Project uses new research to incorporate a number of these advanced technologies into our E4ST power sector model, which offers a detailed representation of the grid and is widely used in policy analysis related to power sector decarbonization.

The related events series covers topics such as carbon capture and sequestration, advanced nuclear energy, enhanced geothermal systems, energy storage, and direct air capture. The series will conclude with an additional event showcasing the results of RFF’s analysis of how various policy proposals will drive investment in and deployment of these technologies.

Rainbow Pools of Huntley Meadows Park

I am almost certain that most of the FMN newsletter readers have seen or heard of the phenomenon described in this article, commonly called rainbow pools. However, since I recently had my first opportunity, unplanned as it was, to photograph them at Huntley Meadows Park I thought I would share my good fortune. I was returning to the nature center following an afternoon of trail monitoring when conditions came together and gifted me with a fleeting glimpse of this colorful phenomenon. I say fleeting because several conditions need to be met to see the rainbow effect: A. decomposed organic surface slime, B. still waters, and C. just the right angle of sun light. And they were all in convergence as I unsuspectingly walked by; and alas, the effect dissolved in ten minutes as condition C degraded.

They are called rainbow pools because the surface coating on the pools resemble oily layers of red, blue, pink, yellow, purple, and colors that may not have a name. The coating is iridescent too like an oil slick but it disperses when disturbed unlike an oil slick, so disturbing the slick is a good way to test between the two.

These rainbow pools are not a sign of pollution but are instead a natural occurrence in most wetlands. Given a combination of very still waters, a few days without rain or wind to disturb surface tension, and the correct angle of light, nature may provide you with a truly colorful experience. I have seen photos that show much more vibrant colors then in the ones I took. My personal observation is that the darker the water (more tannin) the higher the reflective value of the surface material. In addition, these pools sit among hardwood trees so less oil is exuded in the decomposition process of leaf litter when compared to pine or cypress forests. The pools in this section of the park tend to be temporal and, therefore, are less stained with leached tannins and oils creating a more pastel pallet.

HMP Rainbow Pool – photo Jerry Nissley

Most often the sheen forms as a result of decaying vegetation, especially from plant materials that exude natural oils, such as pine cones and needles. Another cause can be anaerobic bacteria breaking down iron in the soil. Once the cells begin to decay, they release a reddish slime material, which floats to the surface. Iron bacteria are of no threat to human health. They are found naturally in soils and water in low numbers and will thrive as more iron becomes available. Yet another example of how wetlands are ecologically important systems due to their high plant productivity and their capacity to recycle nutrients. Bacteria in wetland soils break down organic and inorganic structures.

The rainbow effect is typically seen during cooler months and as the sun approaches the lower degrees of an acute angle such as in the morning or as the sun is setting, providing the appropriate reflective angle. The pools pictured in this article are located in the back still waters off the wooded section of Cedar trail at HMP, not in areas near the creeks or other moving water. These photos were taken on 3 December around 3:30 p.m. as I finished an afternoon of trail monitoring. Other pools can be found in other sections of the park.

So you want to chase a rainbow? Try running down a rainbow pool at Huntley Meadows. But running on the boardwalk is not permitted … those trail monitors will get cha.
