Population Structure, Seasonal Activity, and Larval Density of the Hellbender,
Cryptobranchus alleganiensis, in Pisgah National Forest, North
Principal Investigator: W. Jeffrey Humphries, Clemson University, Clemson,
This project will address several questions that have remained unanswered
pertaining to hellbenders in western North Carolina that are crucial to
the species future conservation plans.
- What is the population size and density of hellbenders in the selected
- How does population structure (ratio of adults, juveniles, and larvae;
adult body size differences) relate to stream size and how does it vary
among main stream stems and tributaries of the main stem?
- Is there a seasonal difference in nocturnal activity of hellbenders
in the selected streams, and how does activity of southern Appalachian
populations compare to activity reported in the central Appalachians?
- What are the best methods for detecting and monitoring larval and
