“…This movement pattern is similar to previous results (King et al 2004, Roe et al 2010. For example, captive-bred juveniles of the northern water snake (N. sipedon) showed low activity and used very limited areas during their early phase of release (Roe et al 2010).…”

“…Also, eastern massasaugas (S. catenatus) translocated into new habitat initially stayed at the site where they were released. After that, they gradually increased their activity, possibly for exploring the new habitat (King et al 2004). In this study, the released captive-bred juveniles might adapt themselves to the new habitat during the first week.…”

“…It is reported that the sunlight through forest light gaps could be sufficient for the basking of juvenile snakes in woodland forests (Blouin-Demers et al 2007). For example, black ratsnake (E. obsoleta) juveniles spent much of their time underground or inside of rock clumps (Blouin-Demers et al 2007), and eastern massasauga (S. catenatus) preferred a habitat where plentiful logs were present (King et al 2004). In addition, approximately 10% of the total of released captive-bred juvenile ratsnakes was counted on trees.…”

To determine the movement patterns, home range, and use of structural features of captive-bred one-or two-year-old Amur ratsnake (Elaphe schrenckii) juveniles in the natural habitat, we radio-tracked a total of 11 juvenile snakes in a mountain valley in Chiaksan National Park, South Korea, between August 21 and September 20, 2010 and between June 13 and July 13, 2011. During the first week of the release, most juveniles moved short distances, daily, but they increased their distances after the first week. The body weight of the juveniles was negatively related with the movement rate (dividing the number of movements by the number of relocations), which was positively related with the mean daily distances moved and the size of both a kernel 50% and 95% home range. During the study period, the juveniles moved daily, approximately 17 m, and the size of the minimum convex polygon and the 50% and 95% kernel home ranges were 1.8 ha, 0.4 ha, and 3.0 ha, respectively. The released captive-bred juveniles were more frequently confirmed underground or on the ground rather than on rocks or on trees. Our results suggest that the body condition of released individuals, the seasonal time of the release, and the existence of available prey and shelters in the habitat should be carefully considered when releasing captive-bred Amur ratsnake juveniles for the rehabilitation of field populations.

“…With documented snake declines (Kingsbury and Attum, 2009), such utility is likely to be necessary. King et al (2004) have already shown that LDT of captive born snakes may be of use in re-establishing extirpated populations of Eastern Massasaugas (Sistrurus c.…”

“…The mitigation of human-snake conflict through the relocation of nuisance animals has been the primary motivation behind snake translocation (Hardy et al, 2001;Nowak et al, 2002;Butler et al, 2005;Kingsbury and Attum, 2009). However, now that snake declines are being documented (Kingsbury and Attum, 2009), translocation has increasingly been investigated as a purely conservation tool, through the augmentation of a current population to increase its viability or the creation of a new population in a part of a species' historical range (Plummer and Mills, 2000;King et al, 2004;Kingsbury and Attum, 2009;Roe et al, 2010). Since translocation is likely to remain a popular management tool, especially for venomous snakes, it is crucial that its effects on subject animals be further studied.…”

The behavioral and physiological effects of long-distance translocation on Western Rattlesnakes (Crotalus oreganus)

Kory Hayden HeikenLong-distance translocation (LDT), the relocation of an animal outside of its home range, is a popular strategy for mitigating conflict between humans and venomous snakes. While LDT has been demonstrated to prevent a snake's return to the location of capture, it may result in increased mortality, magnitude and frequency of movements, and activity range sizes. Thus, it has generally been discouraged. However, the effects of LDT on stress physiology and thermoregulation have gone largely unstudied in reptiles.To elucidate these effects, we conducted an experimental LDT on Western Rattlesnakes (Crotalus oreganus) on Vandenberg Air Force base in California.Fourteen snakes were monitored, beginning in mid July 2012 and ending in early September. Each was implanted with a radio transmitter and iButton temperature data logger within the coelomic cavity. In late August, seven snakes were translocated to similar habitat, approximately 30 kilometers away, where they were monitored for 9-13 days. Prior to translocation, all snakes were tracked every other day, while after translocation all snakes were tracked every day. A 'Before-After Control-Impact' (BACI) experimental design was used, with a dedicated control group, but also with the translocated group serving as control prior to the act of translocation.We collected data on snake body temperatures (T b ) and temperatures (T e ) of physical operative temperature models (OTMs) that simulated non-thermoregulating snakes and allowed for a comparison of habitat thermal quality between our two study sites. Together, T b and T e allowed for a formal assessment of thermoregulatory effectiveness. Additionally, blood concentrations of corticosterone (CORT), the primary stress hormone in reptiles, and testosterone (T), a metric of male reproductive ability that is often negatively associated with CORT, were assayed just prior to translocation and again at the end of the study. During each of the two sampling periods, in addition to baseline hormone concentrations, stressed hormone concentrations were assayed following the application of an acute stressor (the baseline blood draw plus one hour's captivity in a plastic bucket). We also studied the effect of LDT on the CORT and T response (stressed concentration minus baseline concentration). Furthermore, we evaluated how LDT impacted a suite of behaviors related to defense and movement, as well as snake body mass and body condition index (BCI). Finally, we assessed the effects of LDT on movements and spatial use (activity range size). We sought to assess the effects of LDT on movements, spatial use, and behavior in order to facilitate comparison with other translocation studies, as well as to evaluate those impacts in a physiological context. In addition to assessing the impact of LDT on CORT and T separately, we v evaluated a relationship between the two steroid hormones, and, using a model selection approach, we evaluated relationships between CORT and T and movements and spatial use.The thermal quality of the h...
