“…For example, data loggers are increasingly used in research to enable remote collection of physiological information. This often involves surgical implantation, which can cause pain and distress (Hawkins 2004) or can lead to mortality (Quinn et al 2010;Léchenne et al 2012). Studying changes in physiological parameters due to capture is important because morbidity can cause subtle but harmful effects that might go undetected (Cattet et al 2003) and bias research data (Powell and Prolux 2003;Cattet et al 2008).…”

PREFACECompilation of this document was initiated by the Norwegian Directorate for Nature Management in order to establish recommended protocols for capture, chemical immobilization, anesthesia and radiotagging of free-ranging brown bears (Ursus arctos), gray wolves (Canis lupus), wolverines (Gulo gulo) and Eurasian lynx (Lynx lynx). In addition, procedures to ensure proper sampling of biological materials for management, research and banking purposes have been included.The current protocols are based on nearly 3,000 captures of free-ranging brown bears, wolves, wolverines and lynx carried out from 1984 through 2012 in Scandinavia. Some of the results have been published as peer reviewed papers, conference presentations, theses, and reports. However, a large amount of data are still on file and will be published in the future. In addition, comprehensive reviews of the global literature on brown bears, wolves, wolverines and lynx have been carried out in order to include pertinent information from other sources.These protocols have been approved by all ongoing research projects on brown bears, wolves, wolverines and lynx in Scandinavia.We thank the contributors for their cooperative efforts. We also thank the Norwegian Directorate for Nature Management for their support. This document will be updated on a regular basis and will be available in pdf format at:

“…First, capturing and handling are stressful for animals (Cattet et al 2008, Esteruelas et al 2016. Second, although benign in most cases (Bodey et al, 2018), attaching bio-logger devices can influence behavior or even have long-term detrimental effects on individuals (Lechenne et al 2012, Bodey et al 2018.…”

Results from biologging studies are often scaled up to population-level inferences and this begs the question: Are instrumented animals representative of the population given the potential bias in individual selectivity, the influence of capture, handling and wearing bio-loggers? The answer is elusive due to the challenges of obtaining comparable data from individuals without bio-loggers. Using non-invasive genetic data of a large carnivore, the wolverine (Gulo gulo) in Scandinavia, and an open-population spatial capture-recapture model, we were able to estimate and compare survival rates of individuals fitted with GPS collars versus individuals that had never been captured and collared. We found that mortality of GPS collared individuals was 47% lower compared to individuals without GPS collars. While instrumented and non-instrumented wolverines had similar risks of dying from legal culling, GPS collared individuals displayed lower mortality rates due to causes other than legal culling. Reports of positive effects of biologging on the fitness of individuals are rather uncommon and we argue that the most likely explanation is that GPS-collars could shield animals from poaching. Our results highlight the challenges of drawing population level inferences for large carnivores when using data from an instrumented sample of the population.

“…inform conservation, where the use of telemetry devices and recapture often allows for fewer animals to be used. However, these individuals may be subjected to harms from capture, wearing tracking devices, biological sampling, and multiple recapture, [17][18][19] leading to concerns that their welfare is compromised and that they no longer represent the typical individuals of their species. How can reduction and refinement be successfully balanced?…”
