“…Most sensors that provide continuous tracking needed for RTVFs require large batteries or those that can recharge (Millspaugh et al ., ). Therefore, the first criterion to consider is the size of the individual that can be monitored without the attached sensor having a negative physiological, behavioral or demographic effect (Moll et al ., ).…”

Fences can both enhance and detract from the conservation of wildlife, and many detrimental impacts are associated with creating physical barriers. By contrast, virtual fences can restrict, control or minimize animal movement without the creation of physical barriers, and present key benefits over traditional fences, including: (1) no need for construction, maintenance or removal of traditional fences; (2) rapid modification of boundaries both temporally and spatially based on specific conservation concerns; (3) application of novel conservation approaches for wildlife that integrate monitoring, research and management; and (4) social-psychological benefits that may increase support for conservation. We review the various types of sensory, biological and mechanical virtual fences, and the potential benefits and costs associated with fully integrating virtual fences into protected area management and wildlife conservation. The recent development of real-time virtual fences represents the potential for a new 'virtual management' era in wildlife conservation, where it is possible to initiate management actions promptly in response to real-time data. Wide-scale application of virtual fences faces considerable technological and logistical constraints; however, virtual fences are increasingly popular and soon will offer realistic management strategies for both terrestrial and avian wildlife conservation.

“…As suggested by Moll et al [78], the combination of multiple forms of evidence, as included here, allow researchers to obtain a broader view of the effects of marking individuals. For species included in reintroduction programs, where the stresses to each individual are high, it is paramount to understand the effects of devices aimed to monitor individuals before release.…”

Short-term effects of GPS collars on the activity, behavior, and adrenal response of scimitar-horned oryx (Oryx dammah)

et al. 2020

GPS collars have revolutionized the field of animal ecology, providing detailed information on animal movement and the habitats necessary for species survival. GPS collars also have the potential to cause adverse effects ranging from mild irritation to severe tissue damage, reduced fitness, and death. The impact of GPS collars on the behavior, stress, or activity, however, have rarely been tested on study species prior to release. The objective of our study was to provide a comprehensive assessment of the short-term effects of GPS collars fitted on scimitar-horned oryx (Oryx dammah), an extinct-in-the-wild antelope once widely distributed across Sahelian grasslands in North Africa. We conducted behavioral observations, assessed fecal glucocorticoid metabolites (FGM), and evaluated high-resolution data from tri-axial accelerometers. Using a series of datasets and methodologies, we illustrate clear but short-term effects to animals fitted with GPS collars from two separate manufacturers (Advanced Telemetry Systems-G2110E; Vectronic Aerospace-Vertex Plus). Behavioral observations highlighted a significant increase in the amount of headshaking from pretreatment levels, returning below baseline levels during the post-treatment period (>3 days post-collaring). Similarly, FGM concentrations increased after GPS collars were fitted on animals but returned to pre-collaring levels within 5 days of collaring. Lastly, tri-axial accelerometers, collecting data at eight positions per second, indicated a > 480 percent increase in the amount of hourly headshaking immediately after collaring. This post-collaring increase in headshaking was estimated to decline in magnitude within 4 hours after GPS collar fitting. These effects constitute a handling and/or habituation response (model dependent), with animals showing short-term responses in activity, behavior, and stress that dissipated within several hours to several days of being fitted with GPS collars. Importantly, none of our analyses indicated any long-term effects that would have more pressing animal welfare concerns.

“…The camera collars weighed 1.5 kg, or approximately 2% of body mass, based on average weights of adult male white‐tailed deer in the region (Hellickson et al ). An earlier assessment on animal stress due to wearing camera collars demonstrated no difference in fecal glucocorticoid metabolite levels between deer outfitted with and without collars (Moll et al ). We visually observed 3 of the camera‐collar–equipped deer the evening after they were captured and released.…”

Food habits of adult male white‐tailed deer determined by camera collars

Many factors influence what and why animals select the foods they eat. Several methods have been used to estimate food habits of herbivores, but they all have limitations such as defining available foods and misrepresenting particular forages. We evaluated plant consumption by adult male white-tailed deer (Odocoileus virginianus) with camera collars in a semi-enclosed population in southern Texas, USA, during late autumn 2010. We collected 1,241 videos taken at all times of the day and night from 15 camera collars and confirmed consumption of 40 plant species with an 84% probability of identification. Diets of individual deer varied considerably, though there was an apparent preference for prickly-pear cactus (Opuntia engelmannii) and blackbrush acacia (Vachellia rigidula). Our results were consistent with other conventional studies of food habits of deer in the region. Yet, we feel camera collars provide a more thorough and detailed representation of forage species available and consumed. Strategic deployments of camera collars could advance the understanding of nutritional requirements and behavior of deer because a broad array of concurrent data can be collected. Published 2015. This article is a U.S. Government work and is in the public domain in the USA.
