Variations in grizzly bear habitat selection in relation to the daily and seasonal availability of annual plant-food resources

Disentangling the direct and indirect effects of canopy and understory vegetation on the foraging habitat selection of the brown bear Ursus arctos

“…In contrast with our results, previous studies in Canada suggested that understory vegetation such as Vaccinium spp. are heavily utilized by bears in summer (Nielsen et al 2004, McClelland et al 2020). While McClelland et al (2020) suggested that encouraging growth of understory vegetation could maximize food resources regionally for brown bears, our results suggest that understory bamboo impedes bear foraging.…”

Given the dominant understory species generally differ among ecoregions where brown bears inhabit (e.g.…”

Changing spring snow cover dynamics and early season forage availability affect the behavior of a large carnivore

“…(2006). Early season forage availability was assessed using food availability windows determined from 10 field sites in 2018 where field observations and daily camera time‐lapse images were collected throughout the growing season identifying important phonological events for multiple bear‐food species (McClelland, Coops, Kearney et al, 2020). McClelland, Coops, Kearney et al (2020) defined the availability of H. alpinum from snow melt until flowering, as nutrition is poor post flowering (Coogan, Nielsen, & Stenhouse, 2012; Nijland et al., 2013).…”

“…These SDMs, converted to binary presence–absence values, were used to mask each species to their predicted ranges within the study area. Details of these SDMs can be found in McClelland, Coops, Kearney et al (2020).…”

Protein biomarkers in serum as a conservation tool to assess reproduction: a case study on brown bears (Ursus arctos)

“…However, many populations continue to decline resulting in the need for additional management and monitoring approaches ( Dickman et al , 2011 ). Conservation and management strategies of brown bear ( Ursus arctos ) populations have evolved to include a variety of population assessment tools including using barbed wire hair snags to determine abundance and distribution of individuals ( Boulanger et al , 2018 ), fitting animals with satellite GPS-collars that provide detailed spatial data for each individual to identify habitat use ( McClelland et al , 2020 ) and developing complex models to predict survival and habitat selection ( Nielsen et al , 2010 ). To complement these features of brown bear populations (e.g.…”
