Kin-related spatial structure in brown bears Ursus arctos (2005, methodology): “To eliminate auto-correlated data, we used only locations outside the winter den and separated by at least 100 h, which corresponds to the minimum time between the weekly localizations of the bears (Dahle and Swenson 2003b).”
Kernel-based home range method for data with irregular sampling intervals (2006, methodology): “The value of hs in kernel and time kernel calculations was set to 1500 m, which falls between the error in localizing and the median hs calculated with LSCV (Kenward, 2001; Dahle and Swenson, 2003a).”
Estimating Population Size of Elusive Animals with DNA from Hunter‐Collected Feces: Four Methods for Brown Bears (2005, methodology): “She may also have been inside her usual home range because the home ranges based on a minimum of only 16 relocations were underestimates of the true home ranges (Dahle & Swenson 2003a).”
Brown bears possess anal sacs and secretions may code for sex (2011, background): “…Society of London 143 One reason why little is known about olfactory communication in bearsmay be that they are elusive, have large home ranges (our study area: male, 1055km2; female, 217km2) (Dahle & Swenson, 2003), and are difficult to capture (Dahle & Swenson, 2003; Arnemo et al., 2006).”
Large carnivore expansion in Europe is associated with human population density and land cover changes (2021, background): “…and is considered to be a good compromise between information precision and the average home range of these species in Europe that can vary between 100 km2 to more than 1,000 km2, depending on the species and region (Dahle & Swenson, 2003; Jedrzejewski et al., 1996, 2007; Mancinelli et al., 2018).”
Roads and supplemental feeding affect home-range size of Slovenian red deer more than natural factors (2012, background): “An inverse relationship between home-range size and population density has been observed in many other species of various taxonomic groups (e.g., Dahle and Swenson 2003a; Mares et al. 1982; Nagy and Haroldson 1990).”
Terrain use by an expanding brown bear population in relation to age, recreational resorts and human settlements (2007, methodology): “The radio-collared bears were located approximately weekly using standard triangulation methods from the ground or homing from the air (Dahle and Swenson, 2003).”
Estimating effective landscape distances and movement corridors: Comparison of habitat and genetic data (2015, background): “Males and females have intra and inter-sexually overlapping home ranges (Dahle and Swenson 2003) and dispersal primarily occurs by males, while females typically are philopatric (Swenson et al. 1998).”
Ultimate and proximate mechanisms underlying the occurrence of bears close to human settlements: review and management implications (2014, unknown): “Female brown bear body size increases with better food conditions and lower bear densities (Zedrosser et al. 2006), and homerange size decreases with increasing bear densities (Dahle & Swenson 2003b, Dahle et al. 2006).”
POPULATION DENSITY AND FOOD CONDITIONS DETERMINE ADULT FEMALE BODY SIZE IN BROWN BEARS (2006, methodology): “Also here we chose a radius of 17.84 km; the median adult male home range was 1,055 km2 in this area (Dahle and Swenson 2003).”
Should I stay or should I go? Natal dispersal in the brown bear (2007, methodology): “…independently of density, because matrilineal assemblages were formed both in the core and the periphery of our study populations (Støen et al. 2005), which corresponded with high-and low-density areas of the brown bear distribution in Scandinavia (Swenson et al. 1998a, b; Dahle & Swenson 2003b).”
Conservation of brown bear in the Alps: space use and settlement behavior of reintroduced bears (2005, background): “…than females in both brown and black bear populations, at least in summer (mating) and autumn (Huber and Roth, 1993; Powell et al., 1997; Kaczensky, 2000; Dahle and Swenson, 2003a, 2003b), the males introduced in the Italian Alps did not have significantly larger ranges than the introduced females.”
