Scavenging is an alternative foraging strategy to predation for many carnivore species, as they shift between predation and scavenging in response to changes in resource availability. The use of carrion may lead to interspecific competition and is thus influenced by a risk–reward trade-off to balance coexistence with guild-members, where smaller species are expected to be more vigilant due to their vulnerability to larger competitors. We used cameras to investigate the utilization of viscera from the annual moose Alces alces hunt by four sympatric carnivore species: wolf Canis lupus, wolverine Gulo gulo, red fox Vulpes vulpes and pine marten Martes martes in south-central Scandinavia, in relation to body size and habitat. Red foxes had highest probability of visiting viscera sites in both open and forested habitats. Visits by both red foxes and pine martens were longer in open habitats, while number of visits or activity did not differ between habitats. For pine martens, the probability of visiting viscera ... : # Carnivore guild utilization of hunter-provided food sources in boreal forest The data set contains 4 separate csv files used for Wikenros et al. Carnivore guild utilization of hunter-provided food sources in boreal forest Data1_Carnivore guild utilization of hunter-provided food sources in boreal forest.csv Data set used for the analysis of probability of visit to gut pile sites for wolves, wolverine, red fox and pine marten. For details regarding the analysis see Analysis A in Supporting information, Appendix 2 in the study Variables camera.id: gut pile site identity. Repeated 4 times, once per species active: days camera at gut pile site was active, maximum 28 days from deployment. wolf: “dummy variable” for wolf (e.g., 1 - the presence information at the cameras are for wolf, 0 - the presence information at the cameras are for other species) wolverine: “dummy variable” for wolf (e.g., 1 - the presence information at the cameras are for wolverine, 0 - the presence information at the cameras are for other ...
