To test these ideas we exposed laboratory rats to stress during adolescence or to unstressed control conditions. After a 5-week delay, we screened adult foraging behaviours (latency to engage in foraging, number of patch visits) and foraging performance (number of rewards eaten) in both low-threat and high-threat conditions. Wild rodents adjust forging behaviours when cues of predators are present (Orrock, Danielson, & Brinkerhoff, 2004), and foraging performance can be influenced by predation conditions (Pintor and Sih, 2009, Sih, 1982 and Werner and Hall, 1988). Foraging performance can affect 4E1RCat through the ability to mitigate exposure to threat (Morris & Davidson, 2000), attract mates (Keagy et?al., 2009 and Keagy et?al., 2011) and provision offspring (Schwagmeyer & Mock, 2008). Foraging was evaluated both with and without cues of predation, using a foraging task primary structure permitted animals to access a familiar reward by manipulating a novel object; similar assays have been used with captive and wild animals (e.g. humans and chimpanzees, Pan troglodytes: Herrmann, Hernández-Lloreda, Call, Hare, & Tomasello, 2009; spotted hyaenas, Crocuta crocuta: Benson-Amram, Weldele, & Holekamp, 2013; satin bowerbirds, Ptilonorhynchus violaceus: Keagy et al., 2009; house sparrows, Passer domesticus: Bókony et al., 2013).
