“…Home range estimation, migration and movement patterns and habitat preference are the primary results of telemetry studies; however, these data can answer more specific and unique ecological questions, for example, disease transmission [31], predation and co-evolution [32], socio-ecology and breeding behaviour [33], sleep characteristics [34] and physiological studies [35]. In India, most of the studies have centred on the abovementioned primary questions (53.7%, 47.6% and 28.1% of studies, respectively).…”

Three decades of wildlife radio telemetry in India: a review

From 1983, there have been three decades of the application and development of radio telemetry for wildlife studies in India. In this article, we review 82 studies from India, covering 47 species from four taxonomic classes. We examine and discuss the trends in the selection of study species, habitats and objectives of radio-telemetry studies and the functional success of radio collars and tags. A strong bias for study species and study region is observed and researchers generally tend not to look beyond the traditional research questions. Habitats that are difficult to access, such as the Trans-Himalayas, the Himalayas and north-eastern India, are overlooked. Most of the studies aimed to infer primary information only, such as home range, migration and movement patterns and habitat preference (53.7%, 47.6% and 28.1% studies, respectively). We expect these trends to change with time as the development of technology allows researchers to explore further. We investigated the tracking histories of 483 animals and the records of 496 radio collars or tags, but detailed information could be acquired for only 330 collars or tags. Of the collars, 49% malfunctioned before the end of their anticipated life due to a variety of reasons, early battery drainage being the prevalent cause. The performance of different technologies and collar manufacturers was also analysed but the small sample size was an issue for most of the cases. Argos-based collars and tags generally failed to record most of the locations precisely and failed to transmit them successfully. Issues with permissions and capturing animals for tagging, particular to India, are also discussed. A uniform and centralized system for granting permissions and guidelines for capturing and handling animals would be beneficial to future telemetry studies.

“…Kreeger et al (1989) reported that resting body temperature and pulse rate in red foxes were about 408 C and 125 bpm, respectively. In gray wolves, resting body temperature and pulse rate were 39.78 C and 84 bpm, respectively (Kreeger et al 1990a). As with raccoons, coyotes and red foxes in our study exhibited deviations from these values that would be expected given the known cardiopulmonary effects of medetomidine and the likelihood that animals experienced some stress during capture.…”

We chemically restrained free‐ranging coyotes (Canis latrans), red foxes (Vulpes vulpes), and raccoons (Procyon lotor) using medetomidine antagonized by atipamezole. All coyotes and 80% of red foxes were sedated with mean ± standard deviation doses of 0.12 ± 0.02 mg/kg and 0.14 ± 0.02 mg/kg medetomidine, respectively. Seventy‐seven percent of raccoons were sedated with 0.21 ± 0.05 mg/kg medetomidine. In all species we observed occasional movement, muscle rigidity, and partial‐arousal during sedation. Animals were alert within 4.3–8.6 ± 3.5–8.4 min following atipamezole at 0.4 mg/kg. Medetomidine and atipamezole provided safe handling in most animals and rapid recovery without use of a controlled substance. At these doses, biologists in the field should be prepared to administer a supplementary dose of medetomidine to some animals depending on ambient conditions and the objectives of the restraint event.

“…Heart rate, a measure of the sympathetic adrenal medullary (SAM) axis, is considered a sensitive and effective measure of the physiological response to stressful stimuli (Weisenberger et al, 1996;Boissy et al, 2007). Heart rate may also reflect psychogenic responses to other stimuli and events such as agonistic behavior between pen mates, isolation, and feeding when observed heart rates exceed those expected due to physical exertion alone (Kreeger et al, 1990;Palestrini et al, 2005).…”

The potential for captivity to elicit changes in animal behavior and physiology is well known. Recent research on captive populations has examined the effect of feeding protocols, enclosure types, and enrichment programs on indices of stress and displays of species-typical behaviors. We investigated the impact of enclosure type upon captive coyotes (Canis latrans) by examining differences in coyote behavior and heart rate, among 3.3 m 2 kennels (K), 65.5 m 2 small pens (S), and 1000 m 2 large pens (L). Time budgets and repertoire of species-specific behaviors were compared among each enclosure type and to a sample of wild (W) coyotes. Baseline heart rates and heart rate (HR) responses to food delivery and fecal collection (measured as mean heart rate and latency of heart rate to return to baseline) were also compared among treatments. We found that behavioral budgeting, but not repertoire, differed significantly among enclosure types. Relative to small and large pen enclosures, coyotes maintained in kennels exhibited the greatest amount of stereotypic behavior (P < 0.0001). Coyotes kept in large pens were most similar to wild coyotes in the percentage of time they spent performing exploratory
