This is an adult three-lined salamander (Eurycea guttolineata). The three-lined salamander is a stream-adapted salamander, meaning that the larvae are fully aquatic and live in streams. This species is found throughout the southeastern US

Northern dusky salamanders (Desmognathus fuscus) are a species of stream-adapted salamander found throughout the northeastern US. The larvae are aquatic and live in streams, while the adults live on streambanks. This individual is an adult.

This is a red salamander (Pseudotriton ruber), a large stream-adapted salamander species found throughout the eastern US. The larvae of this species are fully aquatic and live in streams, while the adults are more terrestrial and can be found near stream banks.

This is a Northern Slimy Salamander (Plethodon glutinosus). This salamander species is fully terrestrial and can be found throughout the mid-Atlantic and Appalachians. 

To adapt to rising sea levels, coastal wetlands can migrate landward at the expense of adjacent freshwater wetlands and upland ecosystems, but migration can be hindered by natural and anthropogenic barriers. This photo shows marsh migration into an upland forest in Maryland. 

This is a red eft, the juvenile stage of the red-spotted newt (Notophthalmus viridescens viridescens). The juvenile stage of this newt is fully terrestrial, while the larval and adult stages are fully aquatic.

This is a macro photo of unhatched spotted salamander (Ambystoma maculatum) larvae. Spotted salamanders lay their eggs in vernal pools and wetlands in late winter and early spring.

These two American toads (Anaxrus americanus) are in amplexus, or mating position. In this position, the male toad grasps the female toad behind her front legs and does not let go.

A toad (Anaxyrus sp.) inflates an air sac on its neck to make a trilling call. Toads and frogs call during the breeding season to attract potential mates, and each species has a unique call that can be used to identify them.

This adolescent chick, hatched and raised at the USGS Patuxent Wildlife Research Center, is one of ten whooping cranes being released in Louisiana in February 2011. It is a milestone for the state and for the birds, which have not lived in the state since the 1950s.
