Abstract In spite of the fully-hinged shell being the defining characteristic of box turtles, few studies have quantified the behavioural use of the shell in response to predator encounters. While it is often assumed that box turtles simply withdraw into their shell in response to threats, we expected variability among individuals in shell usage and in the degree of head and limb retraction because withdrawal is likely to be costly. We tested the behavioural and physiological responses of free-ranging eastern box turtles to stimuli of varying intensity: observation only, a visual stimulus, a poke on the leg, or a pinch on the leg before being flipped. The more intense the simulated predatory stimulus, the more likely turtles were to fully close their shell. However, stimulus intensity did not affect plasma corticosterone or lactate levels. This may be due to too brief or weak of a stimulus, increased parasympathetic activity, or seasonal effects. Upon capture and during handling, almost all turtles withdrew into their shells and closed their anterior plastron, although fewer closed their posterior plastron, and a few engaged in other behaviours such as biting and urinating. Older, larger turtles were able to close their shells with greater strength than younger and smaller turtles. Our results indicate that in spite of their fully closable shell, box turtles exhibit a graded response to perceived threats. This suggests that full closure of the shell is likely to be costly and occurs only in response to the most intense stimuli.

Few studies have characterized the prevalence of intraerythrocytic parasites in free-ranging chelonian populations or their occurrence across habitats. It is hypothesized that chelonians in different habitats have different exposures to vectors and thus, differences in hemoparasite presence. This study explored the prevalence and intensity of intraerythrocytic parasites by examining blood smears from four species of Illinois turtles: wild Blanding’s turtles (Emydoidea blandingii), eastern box turtles (Terrapene carolina carolina) (EBT), and ornate box turtles (Terrapene ornata ornata) (OBT) and headstarted alligator snapping turtles (Macrochelys temminckii) (AST). Intraerythrocytic parasites were identified in all examined species except for the alligator snapping turtle. For all age classes, Blanding’s turtles had both the highest prevalence of hemoparasites and intensity of infection of all sampled species, while adult Blanding’s turtles had a significantly higher prevalence than juveniles (P<0.05). As this is the first study of hemoparasites in Illinois chelonians, further research is needed to identify the specific species of intraerythrocytic parasite, the potential vectors, and the effect these hemoparasites have on the health of chelonians.

in Canada, Nuttall’s Cottontails (Sylvilagus nuttallii nuttallii) occur in southcentral British Columbia (BC), where they are federally listed as a species of special Concern due to their presumed small populations and limited distribution in fragmented habitats. Their habitat use and movement patterns are poorly known at this northern edge of their distribution. We used livetrapping, radio-collaring, and fecal pellet surveys to examine Nuttall’s Cottontails’ use of remaining patches of native habitat as well as use of human-impacted areas. Cottontails were present in low densities and only about half of presumably suitable patches of native sagebrush-steppe were occupied. Cottontails were more likely to occur in shrubby habitat, but at a fine scale cottontails used areas that had a lower density of shrubs and finer substrates. movement patterns differed significantly between areas of varying habitat quality, with longer movements in natural habitat. one radio-collared male cottontail used anthropogenic habitats adjacent to native habitat; this use corresponds with landowner reports. However, it is not clear whether Nuttall’s Cottontails are able to use anthropogenically-impacted areas to maintain populations or in areas where such habitats are not near native habitats. our results suggest that these animals are rare and occur primarily in remnant patches of shrub-steppe within BC.
