MIGHT NITROGEN LIMITATION PROMOTE OMNIVORY AMONG CARNIVOROUS ARTHROPODS (2003, background): “…demonstrated important roles for habitat structure and physical refuges (MacRae and Croft 1996, Agrawal and Karban 1997, Roda et al. 2000, Norton et al. 2001, Finke and Denno 2002), active prey defenses (Lucas et al. 1998, Snyder and Ives 2001), and predator preferences (Colfer and Rosenheim 2001).”
CONTRASTING TROPHIC CASCADES GENERATED BY A COMMUNITY OF GENERALIST PREDATORS (2001, background): “As the relative intensity of direct predation and indirect effects due to intraguild predation fluctuate, so too will the net impact of predators on herbivore densities (Snyder and Ives 2001).”
INTRAGUILD PREDATION USUALLY DOES NOT DISRUPT BIOLOGICAL CONTROL (2006, background): “For the pest, there was no clear trend; of the 6 studies with a positive effect on the pest, 1 was done on a leaf, 3 were done on branches, 1 was done on groups of 2 – 6 plants and 1 was done on many plants (Table 1). This last study ( Snyder and Ives, 2001 ) actually presents evidence for effects o”
The effect of semi-natural habitats on aphids and their natural enemies across spatial and temporal scales (2014, neutral): “R2 corresponding to marginal R2 (i.e. the variance 1; ⁄P < 0.05; ⁄⁄P < 0.01. actively avoided carabids (Snyder and Ives, 2001).”
A synthesis of subdisciplines: predator–prey interactions, and biodiversity and ecosystem functioning (2004, background): “…predation can cause increasing predator diversity to disrupt the suppression of a pest species; as more predators occur, intraguild predators inhibit the primary predators on a pest species, thus leading to higher pest densities (Rosenheim et al. 1993; Brodeur & Rosenheim 2000; Snyder & Ives 2001).”
Functional benefits of predator species diversity depend on prey identity (2005, result): “There was limited evidence for net negative MPEs in these experiments, unlike many other studies of MPEs (e.g. Snyder & Ives, 2001; Rosenheim, 2001), but this is probably due to the short timescale of the experiments.”
Aphid parasitoids in biological control (2012, background): “However, in other systems where aphids actively defend themselves, sessile aphid mummies can suffer high levels of predation (Snyder and Ives 2001).”
Aphid suppression by natural enemies in mulched cereals (2004, background): “In a similar system involving pea aphids on alfalfa, ground beetles disrupted biological control by parasitoids, while in turn other generalist predators (Nabidae and web spiders) and parasitoids acted additively ( Snyder & Ives, 2001, 2003 ).”
Biodiversity and biocontrol: emergent impacts of a multi-enemy assemblage on pest suppression and crop yield in an agroecosystem (2003, background): “In cases where antagonistic interactions are particularly strong, a multi-enemy assemblage could even exert less biocontrol than would be imposed by a single enemy species (for example, Snyder & Ives 2001 ).”
Can the enemy release hypothesis explain the success of invasive alien predators and parasitoids? (2011, background): “1989; Roy and Pell 2000; Snyder and Ives 2001, 2003), and can exacerbate prey outbreaks by removing key specialists (Rosenheim et al. 1999; Snyder and Ives 2001).”
Video analysis to determine how habitat strata affects predator diversity and predation of Epiphyas postvittana (Lepidoptera: Tortricidae) in a vineyard (2007, background): “However, simply increasing predator abundance (Prasad and Snyder, 2004) or diversity (Snyder and Ives, 2001; Snyder and Wise, 2001; Wilby et al., 2005) does not always result in greater control of target pests.”
Intraguild interactions in aphid parasitoids (2000, methodology): “Snyder & Ives (2000) also observed that disruption of aphid biological control by carabid beetles was higher at low initial aphid densities, suggesting that IGP is to some extent density-dependent.”
Can generalist predators be effective biocontrol agents? (2003, background): “We still have a limited understanding of how pest regulation is affected (or not) by intraguild competition, behavioral interference, predation and cannibalism among predators (105, 172, 173, 182, 185, 186, 199, 200, 210), interactions between specialists and generalists (97, 242), and disruption by”
Aphids and their natural enemies are differently affected by habitat features at local and landscape scales (2012, background): “P. melanarius disrupt the biological control of parasitoid wasps by preying on the aphid mummies (Snyder and Ives, 2001).”
