They point to dams, which slow down the swift currents this amphibian prefers, and development, which produces sediment runoff that fills the rocky nooks hellbenders
use for shelter, the AP reported.
For most species, there is little to no historical data on measures of sperm production, and this lack of historical information is the case for hellbenders
Siltation from development projects often results in the loss of refugia for Hellbenders

Additionally, abnormalities in Ozark hellbenders
are becoming increasingly more severe.
In 2006, at the request of the Saint Louis Zoo, the Conservation Breeding Specialist Group (part of the Species Survival Commission of the World Conservation Union (IUCN), facilitated a workshop that produced a population and habitat viability assessment for the Ozark and eastern hellbenders

The high percentage of eggs that hatched and the high larval survival rates enabled hellbenders
to be released back into the wild in 2011, 2012 and 2013.

by their prominent feathery red gills, and four toes on each front foot and four toes on each hind foot.

DEMOGRAPHY OF HELLBENDERS
IN MIDDLE TENNESSEE: CAUSE FOR CONCERN?
Beginning in 2009, more than 400 young hellbenders
were raised at the Buffalo Zoo as part of DEC's effort to revitalize dwindling populations of eastern hellbenders
In October 2009, Buffalo Zoo reptile and amphibian keepers began working with DEC biologist Ken Roblee to give hellbenders
a helping hand.
Can you tell me if mudpuppies and hellbenders
