Prey limitation drives variation in allometric scaling of predator-prey interactions
(2018-10-01)
Ecologists have long searched for a universal size-scaling constant that governs trophic interactions. Although this is an appealing theoretical concept, predator-prey size ratios (PPSRs) vary strikingly across and within ...
Stomach fullness modulates prey size choice in the frillfin goby, Bathygobius soporator
(Elsevier Gmbh, Urban & Fischer Verlag, 2012-10-01)
Behaviours related to foraging and feeding in predator-prey systems are fundamental to our understanding of food webs. From the perspective of a predator, the selection of prey size depends upon a number of factors including ...
Anurans as prey: an exploratory analysis and size relationships between predators and their prey
(Blackwell Publishing, 2007-02-01)
The vertebrate predators of post-metamorphic anurans were quantified and the predator-prey relationship was investigated by analysing the relative size of invertebrate predators and anurans. More than 100 vertebrate predators ...
Anurans as prey: an exploratory analysis and size relationships between predators and their prey
(Blackwell Publishing, 2007-02-01)
The vertebrate predators of post-metamorphic anurans were quantified and the predator-prey relationship was investigated by analysing the relative size of invertebrate predators and anurans. More than 100 vertebrate predators ...
The effect of refuge on Dermestes ater (Coleoptera : Dermestidae) predation on Musca domestica (Diptera : Muscidae): Refuge for prey or the predator?
(Springer, 2006-11-01)
It is believed that habitat heterogeneity can change the extent of predator-prey interactions. Therefore, in this study we examined the effect of habitat heterogeneity (characterized here as an addition of refuge) on D. ...

The effect of hunger level on predation dynamics in the spider Nesticodes rufipes: a functional response study
(Springer, 2006-09-01)
It is well known that a predator has the potential to regulate a prey population only if the predator responds to increases in prey density and inflicts greater mortality rates. Predators may cause such density-dependent ...
Effect of prey density on intraguild interactions among foliar-and ground-foraging predators of aphids associated with alfalfa crops in Chile: A laboratory assessment
(2011)
Among the aphidophaga guild present in alfalfa [Medicago sativa L. (Fabaceae)], coccinellids forage on aphids most of the time on the foliage and carabids on the ground. The result of their combined effect can be synergistic, ...
The role of predator overlap in the robustness and extinction of a four species predator-prey network
(ELSEVIER SCIENCE BV, 2010)
Predators and preys often form species networks with asymmetric patterns of interaction. We study the dynamics of a four species network consisting of two weakly connected predator-prey pairs. We focus our analysis on the ...
