The pitfalls of ignoring behaviour when quantifying habitat selection (2014, background): “Although some behaviours can occur synchronously as a result of multitasking (Fortin et al., 2004), many behavioural strategies are employed asynchronously, often because the habitat characteristics associated with meeting different needs are spatially segregated.”
The Landscape of Fear: Ecological Implications of Being Afraid~!2009-09-09~!2009-11-16~!2010-02-02~! (2010, unknown): “…and adjust their behavior accordingly, even at the loss of feeding opportunities (Sih 1980, Edwards 1983, Stephens and Peterson 1984, Sweitzer 1996, Gilliam and Fraser 1987, Altendorf et al. 2001, Hernández and Laundré 2005, Fortin et al. 2004, 2005, Ripple and Beschta 2004a, Bergman et al. 2006).”
Reactive responses of zebras to lion encounters shape their predator–prey space game at large scale (2016, methodology): “Fortin et al. (2013) have demonstrated theoretically and empirically for caribou 5 (Rangifer tarandus) that avoidance behaviour might indeed lead to prey aggregation at 6 intermediate distance from their disturbance or threat source, here logging areas.”
Elephant-induced structural changes in the vegetation and habitat selection by large herbivores in an African savanna (2011, background): “Herbivores face trade-offs when selecting a foraging site, such as maximizing access to food while avoiding predators (Illius and Fitzgibbon, 1994; Fortin et al., 2004).”
Individual vigilance of African herbivores while drinking: the role of immediate predation risk and context (2010, background): “By allowing each individual within a group to devote less time to vigilance activities and hence more time to other activities, group living may influence the trade-offs that individuals face between vigilance and foraging activities (Illius & Fitzgibbon 1994; Fortin et al. 2004).”
Personality and foraging decisions in fallow deer, Dama dama (2011, background): “For example, a study of free-ranging bison, Bison bison, and elk, Cervus canadensis, showed that individual differences in vigilance, as measured by scanning time, varied between 0 and 31% and were inversely related to bite rate (Fortin et al. 2004).”
Group-size-dependent association between food profitability, predation risk and distribution of free-ranging bison (2009, background): “Group members may benefit from dilution effects and cooperative defence against predators (Dehn 1990; Fortin et al. 2004b; Isvaran 2007).”
Diel predator activity drives a dynamic landscape of fear (2017, unknown): “…Creel 2007, Creel et al. 2008, Liley and Creel 2008, Gower et al. 2009, Middleton et al. 2013a) because they can simultaneously process their food and scan their surroundings (Fortin et al. 2004, Gower et al. 2009) as well as escape wolves that attack them (MacNulty et al. 2012, Mech et al. 2015).”
Hunting increases vigilance levels in roe deer and modifies feeding site selection (2008, unknown): “Exclusive vigilance has been reported in roe deer (Mrlik 1998), bison, elk (Fortin et al. 2004) and free-ranging impalas Aepyceros melampus (Blanchard & Fritz 2007).”
Linking wolves to willows via risk-sensitive foraging by ungulates in the northern Yellowstone ecosystem (2006, background): “…and Lung, 2003), researchers are just beginning to obtain information about the anti-predator tactics of ungulates regarding their use of habitat (Bergman, 2003; Fortin et al., 2005, Mao et al., 2005) and foraging patterns (Ripple et al., 2001; Ripple and Beschta, 2003, 2005b; Fortin et al., 2004).”
