    • ...Intraguild predation, defined as predator–prey interactions among consumers that share the same trophic level (Holt and Polis 1997), is ubiquitous in aquatic and terrestrial systems (Werner and Gilliam 1984)...
    • ...Theory predicts that coexistence is possible when intraguild prey are better competitors for a single, shared resource (Holt and Polis 1997), but empirical observations demonstrate coexistence occurs even when predators are better competitors (Navarrete et al. 2000)...

    • ...Furthermore, theoretical investigations have revealed parameter regions that lead to both stabilizing and destabilizing dynamics in simple models (Holt and Polis 1997; McCann and Hastings 1997; Kuijper et al. 2003; Tanabe and Namba 2008; Namba et al. 2008; Verdy and Amarasekare 2010)...
    • ...Traditional analyses of IGP models reached the following: (1) the coexistence of all species in the system is contingent on the greater competitive abilities of Y, relative to the omnivore Z , to consume the shared resource (Holt and Polis 1997; McCann and Hastings 1997); (2) enrichment destabilizes the system (Holt and Polis 1997; Diehl and Feissel 2001); (3) if the gain of the omnivore by predation on the consumer exceeds the negative ...
