Assesses the conservation status of Clemmys insculpta, the wood turtle, which ranges discontinuously in north-eastern North America and is confined to specific habitats associated with streams. Information is included on the turtle's geographic distribution in Canada and the United States, population size and trends, protection status, habitat, general biology, factors limiting the turtle population size and distribution, and the special significance of the species. Concludes with brief discussion of the current consensus regarding the status of the species and a recommendation for designation of the species as vulnerable.

I investigated the habitat selection of wood turtles (Glyptemys insculpta) in a landscape within active agriculture and assessed the risk of agricultural practices. I tracked 23 wood turtles and recorded their habitat use versus availability on a 3rd and 4th order scale. I found that wood turtles preferred fields over the forest and that hay fields are likely an attractant to wood turtles due to high food availability and low canopy cover. Wood turtles used the hayfields during the hay harvest season, and stayed close to field edges. I monitored the movement response of wood turtles as they were approached by agricultural machinery and found that most turtles could not successfully escape the mower. My study shows that agriculture poses a high risk to wood turtles in an agricultural landscape and management strategies are necessary to prevent populations from extirpation.

The wood turtle, Glyptemys insculpta, is listed as threatened federally in Canada and provincially in Nova Scotia (NS) and New Brunswick (NB). Historic surveying for G. insculpta in these provinces has been arbitrary and geographic knowledge gaps persist. To address these gaps, this research developed species distribution models for NS and NB using Maxent software, G. insculpta occurrence data, and environmental data relevant to the species' ecology. Resulting important model variables included 'Elevation', 'Distance to Alder', and 'Watercourse Density'. The model outputs were used to guide field surveys, which recorded G. insculpta occurrences at twelve new sites. In NS, the model output's prediction of G. insculpta distribution overlapped with 80.4% of identified core habitat, but only 4.6% of this predicted distribution was within protected areas. The findings will contribute to conservation of this at-risk species by predicting its distribution, and in doing so, inform future survey efforts and conservation decisions.

Herein, I examine two aspects of overwintering ecology of wood turtles (Glyptemys insculpta) in Nova Scotia, Canada. The research was conducted in a region that supports a large population of G. insculpta despite being located near the northeastern edge of the species' range. Using radio telemetry, I monitored turtles across two consecutive winters to investigate microhabitat properties that are critical to hibernation in G. insculpta. The sample population overwintered in a range of habitats; some different from those reported elsewhere in the species' range. Conventionally, wood turtles rely on highly oxygenated rivers, and have been previously described as hypoxia-intolerant. Data from this study indicate that wood turtles are capable of surviving dormancy in hypoxic oxbows. Accordingly, I propose that G. insculpta is a hypoxia-tolerant species, and further hypothesize that a diversification of overwintering strategies may allow the local population to adapt to environmental stochasticity associated with life at the edge of the species' range. I also examined communal hibernation and seasonal site fidelity and show the first known accounts of male-female congregating, mating, and synchronized spring emergence in G. insculpta, and suggest that communal hibernation is linked to increased mating opportunities. Using historical telemetry data for a subsample of mutual turtles, long-term patterns in seasonal site fidelity revealed that among adult females, differing life history strategies may exist. Although migratory females are often viewed as outliers by decision makers, the survival and genetic contribution of these 'risk takers' may be critical to local populations, and ultimately effect evolution of the species. Above all, the findings have implications for conservation in that they warrant a new definition of critical overwintering habitats for G. insculpta, and highlight why the dismissal of outlying seasonal movement data can result in inadequate protection of corridors between hibernacula and nesting sites.
