A Test Of Predator Avoidance By Larvae Of The Blue Ridge Two-Lined Salamander (Eurycea Wilderae) In Appalachian Streams, Taylor Hopkins, Emmeline Lombard, Carlos D. Camp
Georgia Journal of Science
Larval Blue Ridge Two-lined Salamanders (Eurycea wilderae) are significant components of Appalachian streams, reaching densities up to 100/m2. Not surprisingly, these salamanders fall prey to many types of predator. In order to test the hypothesis that larval E. wilderae actively avoid predators, we paired them against a variety of predators of this species. Predators included Banded Sculpins (Cottus carolinae), Chattahoochee Crayfish (Cambarus howardi), and Spring Salamanders (Gyrinophilus porphyriticus), both adult and larval. We placed larvae in a 1-m metal trough filled with water with a predator placed in a cage …
A Test Of Food Partitioning Between The Aquatic Larvae Of Two Parapatric Species Of Two-Lined Salamander (Eurycea Bislineata Species Complex) In A Zone Of Sympatric Contact, Carlos D. Camp, S. Michael Owensby, Emily Benfield, Jessica A. Wooten
A Test Of Food Partitioning Between The Aquatic Larvae Of Two Parapatric Species Of Two-Lined Salamander (Eurycea Bislineata Species Complex) In A Zone Of Sympatric Contact, Carlos D. Camp, S. Michael Owensby, Emily Benfield, Jessica A. Wooten

Phylogenetically related species with similar ecologies often partition resources when in sympatry. Food is an important factor in the co-occurrence of sympatric salamanders, and food partitioning occurs in a variety of sympatric, similar species. Several members of the Two-lined Salamander (Eurycea bislineata) species complex are largely parapatric but co-exist within a narrow zone of sympatric contact. Because larvae of these salamanders frequently occur in very high densities, we tested the hypothesis that larvae of the Blue Ridge Salamander (E. wilderae) and the Southern Two-lined Salamander (E. cirrigera) partition food in sympatry in northeastern Georgia. …
