Growth And Survival Of Wild And Head-Started Blanding’S Turtles (Emydoidea Blandingii), Callie Klatt Golba

Graduate Research Theses & Dissertations

Blanding’s Turtles (IUCN Endangered) are long-lived reptiles with delayed sexual maturity. Anthropogenic landscape changes have increased threats to juvenile turtles, resulting in unnaturally low recruitment. Head-starting has become a popular conservation strategy that aims to increase juvenile recruitment by avoiding the increased predation of the vulnerable nest and hatchling age-class. However, there is still debate about whether or not it is an effective management tool. Assessments of head-starting are becoming more prevalent, but long-term studies are needed to critically evaluate the success of such interventions. In particular, information is needed on how head-starts fare compared to wild-born turtles. The Lake …

Home Range, Habitat Use And Thermal Ecology Of The Florida Box Turtle (Terrapene Bauri) On An Anthropogenic Island In Southwestern Florida, Christina Demetrio Jan 2019

Home Range, Habitat Use And Thermal Ecology Of The Florida Box Turtle (Terrapene Bauri) On An Anthropogenic Island In Southwestern Florida, Christina Demetrio

Antioch University Dissertations & Theses

Limited information is available on the ecology of Terrapene bauri (Florida Box Turtle) in mangrove ecosystems. Radio-telemetry and iButton data loggers were used to study the home range, habitat use, and thermal ecology of ten Florida Box Turtles on an anthropogenic island in the mangrove-dominated region of southwestern Florida. The effects of weather variables on movement and activity were also examined. Home range analysis using Minimum Convex Polygons (MCP) and Kernel Density Estimates (KDE) determined an average home range size of 0.81 ha (MCP) and 2.32 ha (95% KDE). Box Turtles moved an average distance of 6.3 m per day …
