MARION — Learn about amphibians at the Marion Natural History Museum.

Herpetologist Scott Smyers will present a study of Wood Frog populations in high elevations in the White Mountains of New Hampshire on Friday, April 12 from 6:30 to 7:30 p.m.

Smyers is a vice president and senior scientist at Oxbow Associates and has studied the behavior and ecology of amphibian and reptile species native to the eastern United States for more than 20 years. He has also led field studies for pond-breeding amphibians using various trapping techniques.

Smyers’ experience with amphibians includes laboratory studies of three species of pond-breeding salamanders in southern Louisiana including Ambystoma opacum, Ambystoma maculatum and Ambystoma talpoideum.

Take a look at ecosystems that are hidden in plain sight, many along the well-traveled Appalachian Trail. Guests will learn about amphibian species distribution, changes in communities and shifts in calling phenology that reveal how complicated these ecosystems are for amphibian survival.
