Yellow Spotted Salamander (Ambystoma maculatum) Egg Sac

A light rain sprinkled the South Coast of Massachusetts on Friday night with temperatures still hovering in the high 30s/low 40s.  We had not yet seen any sign of spotted salamander mating congresses and no egg sacs so far this season because temperatures have been unfavorable.  In fact, we experienced an April Fool’s Day snow storm this year.  Nothing to write home about, only a couple of inches of heavy flakes, but still enough to delay the kick start to spring.  Even frogs and spring peepers have been few and far between.  The wild seems eerily silent this year.

Spotted Salamander Individual Egg

After last night’s gentle rain, Turtle Journal opted to scour the shallow channels of Marion’s abandoned Goldwitz Bog this morning, and we found a small concentration of spotted salamander egg sacs in the very early stage of development.  Obviously, since it was broad daylight, we saw no spotted salamander specimens.

Development of Spotted Salamander Eggs and Larvae

Combining original Turtle Journal footage from last season with material from Yale University in 1920, the video clip above documents the development phases of spotted salamander eggs.  The eggs we found today in the abandoned Goldwitz cranberry bog, as pictured above, are clearly at early stages of development.  You can read about last year’s nighttime adventure to discover the spotted salamander mating congress under Turtle Journal articles ”Slithering Salamanders, Turtleman!  Why Did the Spotted Salamander Cross the Road?”  and “Portrait of a Spotted Salamander.”  (ASIDE:  Fortunately, you won’t have to read about how the Turtleman got a permanent “dueling” scar across his nose while scrambling through the bog’s thorny bushes in the dark of night.)

Spotted Salamander Egg Sacs in Goldwitz Bog

Today’s egg sacs were in the same approximate location of last year’s mating congress, although much, much fewer in number.  We expect to see more mating activity over the coming nights, especially if there’s any warm rain in the forecast.

Close Inspection Show Early Developmental Stage of Eggs

And the camera zooms even further to show the eggs/embryos in early stages of development.

Extreme Close Up of Individual Egg Sacs

With an extreme close up of individual egg sacs, and comparing them to the video above, you can clearly see how early in the development process these larvae remain.  We suspect … based on our continuing observations of this area … that the eggs may have been deposited last night, April 1st/2nd.

Entire Eco-System Springs to Life

Sometimes we forget how important these events are to the entire eco-system as colonies of interesting critters erupt around salamander and frog mating aggregations, a magical time on the South Coast when the entire bog springs to life and to sound.  We leave you with a trilling chorus of “A Little Amphibian Night Music” … an original creation by the Slithering South Coast Croakers.

Ars Gratia Artis — Driftart of Cape Cod

Wednesday, December 3rd, 2008

“Home with a View” Driftart on Cape Cod Bay

L’art pour l’art, the French expression and philosophy that transformed itself into the haughty Latin ARS GRATIA ARTIS encircling the Metro-Goldwyn-Mayer roaring lion, championed the purity of art solely for art’s sake.  Within this philosophy, a work of art possesses inherent and intrinsic value distinct from any moral lesson or utilitarian purpose.  Art is simply art.

Anonymous Driftart Scattered Along Deserted Beaches

While it may prove a difficult challenge to maintain that purist philosophy in the chic galaries and trendy studios of SoHo, the abandoned beaches of wintry Cape Cod afford the lonely pleasure of artistic expression beyond the smothering glare of adoring fans and nattering critics and without any thought of commercialism.  In fact, ephemeral driftart goes unseen and unappreciated by anyone except its creators, transient flocks of waterfowl, a stray seal or two that may haul up to bask nearby, and a few layered, bundled, wind-blown and eccentric hikers.

No Place Like Home for the Holidays

The Turtle Journal calls these creations driftart, a contraction of drift and art.  When we first explored the winter beaches of the Outer Cape, wandering miles from the nearest landing, we were surprised to encounter driftart scattered randomly along the Great Back Beach from Chatham to Provincetown, and the long, lonely stretches of bayside beach from Provincetown to Jeremy Point in Wellfleet, more than 45 miles of sand, surf, wrackline and little else from each November through March. 

“Home Sweet Home” Driftart

Where nothing had been yesterday, a collage of flotsam and jetsam springs to life, created first by the inspiration of a single artist, then augmented by other hardy designers and shaped into a unique community artwork.  Every few days until an Atlantic storm erases the entire masterpiece, someone adds a touch here or links existing objects there to invoke a new effect.  Located quite literally in the middle of nowhere, seen by no one, shaped for the pure, simple pleasure of anonymous artists who create it, and vanishing into unnoticed oblivion within a blink of the storm god’s whim, these driftart works are a true manifestation of arts for art’s sake.

Blackfish Creek Driftart

Sightings of actual driftartists are as rare as credible photographs of bigfoot or glimpses of urban graffiti taggers.  They create their works outside the view of civilization, during times when fleeting, summer civilization has returned to its mainland roots and when the Outer Cape has resumed its natural state of raw, uncontrollable wildness.  We suspect you’d be surprised by their identity and they’d be equally surprised to be viewed as artists.  Yet, we like to think of these individuals as kindred warriors to those prehistoric cave artists of 30 millennia ago who created masterpieces of expression in cryptic, inaccessible underground locations unlikely ever to be seen by a fawning public.  And so it is with Cape Cod driftartists who build their creations along equally inaccessible winter beaches with the sure knowledge that their work will soon disappear unseen and unnoticed into the ocean depths.  Art of art’s sake.  Ars gratia artisL’art pour l’art

 

The New Naturalists: Next Generation of Herpetologists

Young Herpetologist Meets Her First Terrapin Hatchling

The most sacred duty of any naturalist, especially one with thinning silver locks, involves sharing the experience of Nature and recruiting successors among the next generation to continue the critical mission of observation, documentation and conservation.  While my colleagues and I employ undergraduate and graduate interns each season to “learn the trade” of field science, our special joy comes from opportunites to engage with the youngest scientists, those for whom an adventure in the wild becomes a transformational experience that may change the course of their lives and the future of our world. 

Don Lewis and Young Herpetologists with Terrapin Hatchlings

Partnering with such exceptional conservation advocates as the Massachusetts Audubon Society, the National Marine Life Center, the Cape Cod Museum of Natural History, and Massachusetts Marine Educators (among too many others to mention in a short post), we have had the privilege to introduce children from nine months to nine decades to Nature through the unparalleled teaching model of turtles.  Seemingly helpless hatchlings melt the hardest hearts.  I’ve watched jaded curmudgeons with expressions so sour they could change sunshine into hail; I watched their eyes mist as they witnessed a tiny hatchling poke its head through its eggshell at the instant of birth.  For children who come to the field with fewer preconceptions of the natural world, these interactions are pure joy.

Discovering a Hatchling as It Emerges from the Egg

Because turtles, and especially hatchlings, appear so accessible to children, they create an immediate and tangible link with Nature.  In decades of wildlife research and education, we have never encountered a person WITHOUT a turtle story to tell.  Often an octogenarian will smile the smile of a todler as her eyes beam and she tells the tale of how her dad introduced her to a baby turtle he had found in the pond behind their home.

Baby Meets Baby

We can never forget the young girl who eagerly and tenderly held a four-year-old snapping turtle at the Earth Day celebration at Mass Audubon’s Wellfleet Bay Wildlife Sanctuary in 2003.  We wonder how she showed no fear of what this then timid turtle would become as it grew into a mighty and fearsome snapper.  She simply felt the joy of touching Nature in such a personal way.

Four-Year-Old Meets Four-Year-Old Snapping Turtle

During field season, we use every opportunity to involve children in our research, especially when releasing critters back into the wild.  On the beaches of the Outer Cape, the setting is perfect for youngsters to meet turtles in a completely natural venue and to learn about them in ways that books simply can never convey.

Turtles Create Transformational Moments

A message from today’s post?  Take every opportunity to introduce children to Nature and show them critters in their natural habitat.  The rewards of the moment will be enormous as you see pure, honest joy burst across their faces.  But this singular experience will pay dividends for a lifetime as memories form touchstones that will shape the course of their lives and the future of our world.  Bring your family into Nature and see what futures you, too, can create.
