QUANTIFYING SEASONAL HOME RANGES OF CAPTIVE-REARED. RECENTLY-RELEASED JUVENILE BLANDING’S TURTLES (EMYDOIDEA BLANDINGII)
Substantial threats to reptile species biodiversity have become apparent in the last few decades. This is partly caused by significant losses in grasslands and their associate prairie-wetland ecosystems. One Midwestern prairie-wetland species, the Blanding’s turtle (Emydoidea blandingii), is at risk of extirpation due to habitat loss, fragmentation, and increased predator populations. Consequently, many wildlife managers have invested in the conservation of this species. However, much of the spatial requirements for juveniles of this species are understudied. We released two yearly cohorts of juvenile, captive-reared E. blandingii in a prairie wetland in 2016 and 2017. Using ground-based radio-telemetry, we calculated seasonal home ranges (HR; spring, summer, fall, and annual) from May 2016 – November 2016, and May 2017 – November 2017. We calculated HRs using Minimum Convex Polygons (MCP) and Kernel Density Estimates (KDE; at 50% and 90% CI) using ArcMap 10.4.1. For the 2016 released cohort, we found significant differences in 90% HRs between the spring and fall compared to summer and annual estimates, with HR size largest in the summer. This data will provide wildlife managers with valuable insight into the ecology of captive-reared and released juvenile E. blandingii.
