Modeling critical habitat breadth for Gopherus tortoises

A multi-year, multi-institution collaboration

Kevin Shoemaker

The A.P.E. lab is leading a large, multi-institution collaboration investigating the climate resilience of populations of gopher tortoise (Gopherus polyphemus) and Mojave desert tortoise (Gopherus agassizii). In this project, funded by the Department of Defense (SERDP program), we are building models of tortoise vital rates (age-structured survival, fecundity) as functions of environmental and climatic covariates and simultaneously assessing for evidence of local behavioral and physiological…
