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…

Dr. Shoemaker’s PhD dissertation focused on the conservation of bog turtles (Glyptemys muhlenbergii) in New York and Massachusetts. Building upon an existing capture-recapture dataset, he estimated population vital rates and abundance of these turtles in small wetlands in eastern New York (Dutchess County) and assessed for evidence of dispersal within a complex of multiple neighboring wetlands. His work also used microsatellite genotypes to further assess gene flow within these wetland…
