Prey selection and dietary response by wolves in a high-density multi-species ungulate community (2011, background): “Several studies have reported encounter rates to be higher for larger groups of prey (Hebblewhite and Pletscher 2002; Creel and JAJr 2005), probably because of their increased detectability.”
Responses of elk herd size to fine-scale spatial and temporal variation in the risk of predation by wolves (2005, unknown): “However, Hebblewhite & Pletscher (2002) also concluded that decreasing herd size could reduce the rate of encounter with wolves, and our data support this conclusion.”
Habitat heterogeneity and mammalian predator–prey interactions (2012, methodology): “These data should therefore be combined with data from radiotelemetry (Hebblewhite & Pletscher 2002, Andruskiw et al. 2008), which allows the track to be calibrated against time.”
Elk population dynamics in areas with and without predation by recolonizing wolves in Banff National Park, Alberta (2002, background): “The positive relationship between elk group size and elk density, combined with increased encounters and kills in larger herds, might provide a mechanism for such density-dependent predation (Hebblewhite and Pletscher 2002).”
Group territoriality and the benefits of sociality in the African lion, Panthera leo (2009, result): “Alternative strategies in response to risk was predicted by Jarman (1974), and a similar pattern was seen for elk under threat of attack by wolves (Hebblewhite & Pletscher 2002).”
Group-size-dependent association between food profitability, predation risk and distribution of free-ranging bison (2009, background): “Prey are more conspicuous to predators when they are in large versus small groups (Lindström 1989; Hebblewhite & Pletscher 2002).”
Evaluation of Potential Factors Predisposing Livestock to Predation by Jaguars (2007, background): “Because food resources inside each allotment were equally spaced we assumed that grouping was a response to increased perceived predation risk (Hebblewhite and Pletscher 2002).”
Predation by wolves ( Canis lupus ) on roe deer ( Capreolus capreolus ) in north-eastern Apennine, Italy (2004, background): “Second, Gerard et al. (1995) found a positive relationship between the proportion of open habitat and group size of roe deer, and Huggard (1993) and Hebblewhite & Pletscher (2002) observed an increase in encounter rates and attack success of wolves on large ungulate groups.”
Sex-specific behavioural responses of elk to spatial and temporal variation in the threat of wolf predation (2007, background): “Other studies suggest that large groups are encountered and attacked by predators more often than expected by chance (Krause & Godin 1995; Creel & Creel 2002; Hebblewhite & Pletscher 2002 ).”
Spatial decomposition of predation risk using resource selection functions: an example in a wolf /elk predator /prey system (2005, background): “…decompositions of predation risk have been presented by Wrona and Dixon (1991) for an aquatic planarian /trichopteran predator / prey system and by Hebblewhite and Pletscher (2002) for a wolf (Canis lupus ) /elk (Cervus elaphus ) system, but neither of these studies focused on the spatial…”
MULTI-TASKING BY MAMMALIAN HERBIVORES: OVERLAPPING PROCESSES DURING FORAGING (2004, background): “Carnivores often spend substantial amounts of time searching for and pursuing their prey (Fanshawe and Fitzgibbon 1993, Krause and Godin 1995, Hebblewhite and Pletscher 2002), and after prey are killed, may require several minutes to several days to consume the prey.”
Socioecological influences on the reproductive success of female mountain gorillas (Gorilla beringei beringei) (2007, background): “However, small-bodied and/or nocturnal species may fare better in smaller groups if concealment is more important than detection (Janson and Goldsmith 1995; Hill and Lee 1998; Hebblewhite and Pletscher 2002).”
Scales of movement by elk (Cervus elaphus) in response to heterogeneity in forage resources and predation risk (2005, unknown): “Thus, spatial separation from wolves is likely unattainable for elk in a landscape like ours and modifying group sizes (Hebblewhite and Pletscher 2002) or remaining close to cover (Kunkel and Pletscher 2000; Woff and Van Horn 2003) may be more profitable strategies.”
