Foliar and ground-foraging predators of aphids associated with alfalfa crops in Chile: Are they good or bad partners?
(TAYLOR & FRANCIS LTD, 2007)
Carabids and coccinellids are the most abundant aphid predators in alfalfa. Depending on the amount of prey consumed, the impact of their combined effect can be additive, antagonistic, or synergistic. Laboratory trials ...
Community-wide responses to predation risk: Effects of predator hunting mode on herbivores, pollinators, and parasitoids
(2018-01-01)
1. Flower visitation by herbivores and pollinators often occurs simultaneously, but their potential contrasting responses to predation risk are rarely investigated in concert. Predator avoidance behaviour is common in ...
Black sea urchins evaluate predation risk using chemical signals from a predator and injured con- and heterospecific prey
(Inter-research, 2011-01-01)
The traits related to foraging and eating are crucial to our understanding of food webs. The use of signals to detect predators has strong relevance for prey survival. The black sea urchin Echinometra lucunter cohabits ...

Instabilidade difusiva em um modelo presa-predador generalista
(Universidade Federal de Santa MariaBrasilMatemáticaUFSMPrograma de Pós-Graduação em MatemáticaCentro de Ciências Naturais e Exatas, 2017-01-26)
In this work, we investigate the pattern formation of a reaction-diffusion generalist
predator-prey system with constant alternative food source and a Holling type III
functional response. The local model can exhibit up ...
