115 | Everything Ridge-nosed Rattlesnakes

Dr. Jenkins sits down with Dr. Andrew Holycross to discuss one of
the rarest rattlesnakes in the United States. They start by
talking about the species' distribution, which is primarily in
Mexico, and focus on the two subspecies found in the United
States: the Arizona and New Mexico Ridge-nosed Rattlesnakes. The
beginning of the podcast covers the natural history and ecology
of the species, including movement, habitat use, genetics, and
diet. They then discuss the various threats that have led to the
New Mexican subspecies becoming endangered and declines in the
other subspecies. Finally, they talk about the future of these
Sky Island Rattlesnakes in the face of climate change, including
management techniques such as genetic augmentation and assisted
migration.
