• Cattle grazing, raptor abundance and small mammal communities in Mediterranean grasslands (2007, background): “The effects of predators on small mammals can be direct or indirect (Brown et al., 1999; Kotler et al., 2002; Torre & Dı́az, 2004).”
• APPREHENSION AND TIME ALLOCATION IN GERBILS: THE EFFECTS OF PREDATORY RISK AND ENERGETIC STATE (2004, methodology): “The gerbils appear to use a combination of time allocation and apprehension that keeps risk-per-seed-harvested constant over the course of the night (Kotler et al. 2002).”
• Patch use, apprehension, and vigilance behavior of Nubian Ibex under perceived risk of predation (2006, methodology): “For instance, they can be quantified by offering a forager artificial food patches (feeding trays) that differ in micropatch (sections within the feeding tray) structure or complexity (Kotler et al. 2002).”
• NIGHT FEEDING BY GUPPIES UNDER PREDATOR RELEASE: EFFECTS ON GROWTH AND DAYTIME COURTSHIP (2004, background): “Animals have behavioral control of where and when to forage, and it has become axiomatic that predation threat plays a prominent role in shaping use of space and time by foraging animals (e.g., Kerfoot and Sih 1987, Houston and McNamara 1999, Kotler et al. 2002).”
• Trophic cascades : the primacy of trait-mediated indirect interactions (2004, background): “Fundamentally then, there is a flexible interplay between predators and prey (Sih 1984; VanBaalen & Sabelis 1993; Brown et al. 1999; Bouskila 2001; Kotler et al. 2002; Lima 2002; Krivan & Schmitz 2003).”
• Temporal variability, threat sensitivity and conflicting information about the nature of risk: understanding the dynamics of tadpole antipredator behaviour (2009, unknown): “Publishe their activity levels according to lunar cycles (Kotler et al. 2002), avoiding foraging during periods of full moon light, presumably to avoid nocturnal predators (Clarke 1983; Bowers 1988).”
• Sleeping under the risk of predation (2005, background): “A predator that specializes on a given prey species will most likely match any change in the prey’s activity pattern (also see Kotler et al. 2002); hence, major changes in prey sleep phasing in specialized predator–prey systems are unlikely.”
• Comparative ecology of desert small mammals: a selective review of the past 30 years (2011, methodology): “Kotler et al. (2002, 2004a) quantified this by presenting gerbils with paired foraging trays in which seeds were either evenly distributed within a sandy matrix or were distributed only in the lower half of the sandy matrix.”
• Hazardous duty pay and the foraging cost of predation (2004, background): “In this regard, gerbils (Gerbillus andersoni and G. pyramidum) are known to show heightened apprehension when predators are most active, in riskier microhabitats, and during moonlit hours of the night when predators are most lethal ( Kotler et al. 2002 ).”
• MULTI-TASKING BY MAMMALIAN HERBIVORES: OVERLAPPING PROCESSES DURING FORAGING (2004, background): “Still, the trade-off between food intake rate and predation risks might be such that optimal foragers must accept a certain reduction of food intake due to vigilance (Lima and Dill 1990, McNamara and Houston 1992, Brown 1999, Brown et al. 1999, Kotler et al. 2002).”
