“…The mean current modeled suitability for K. flavescens within Illinois, Iowa, and Missouri, where the species is currently threatened with extirpation (Christiansen et al., ), was 12% and ranged from 0% to 50%. By 2050, the suitability of this region increased.…”

“…Although the IUCN () lists K. flavescens as a species of Least Concern, Christiansen et al. () documented recent severe declines in isolated populations in Illinois, Iowa, and Missouri. These declines are thought to be due primarily to a combination of predation and habitat loss (Christiansen et al., ).…”

“…Specifically, climate change is predicted to affect individual growth rates (Du & Ji, ), population sex ratios (Janzen, ), fecundity (Ficetola, Thuiller, & Padoa‐Schioppa, ), reproductive phenology (Lovich et al., ), and predation rates (Chessman, ; Christiansen et al. ). Most studies examining how climate change may affect chelonians have focused on sea turtles (e.g., Hawkes et al., ; Rees et al., ), with relatively little attention given to freshwater turtles.…”

Chelonians are expected to be negatively impacted by climate change due to limited vagility and temperature‐dependent sex determination. However, few studies have examined how freshwater turtle distributions may shift under different climate change scenarios. We used a maximum entropy approach to model the distribution of five widespread North American Kinosternon species (K. baurii, K. flavescens, K. hirtipes, K. sonoriense, and K. subrubrum) under four climate change scenarios. We found that areas with suitable climatic conditions for K. baurii and K. hirtipes are expected to decline substantially during the 21st century. In contrast, the area with suitable climate for K. sonoriense will remain essentially unchanged, while areas suitable for K. flavescens and K. subrubrum are expected to substantially increase. The centroid for the distribution of four of the five species shifted northward, while the centroid for K. sonoriense shifted slightly southward. Overall, centroids shifted at a median rate of 37.5 km per decade across all scenarios. Given the limited dispersal ability of turtles, it appears unlikely that range shifts will occur rapidly enough to keep pace with climate change during the 21st century. The ability of chelonians to modify behavioral and physiological responses in response to unfavorable conditions may allow turtles to persist for a time in areas that have become increasingly unsuitable, but this plasticity will likely only delay local extinctions.
