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 ...
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 ...
The effectiveness of post-contact defenses in a prey with no pre-contact detection
(Urban und Fischer VerlagJena, 2013-06)
Most empirical and theoretical papers on prey–predator interactions are for animals with long-range detection, animals that can detect and react to predators long before these touch the prey. Heavy-bodied and chemically ...
Prey choice by Nesticodes rumpes (Araneae, Theridiidae) on Musca domestica (Diptera, Muscidae) and Dermestes ater (Coleoptera, Dermestidae)
(Amer Arachnological Soc, 2006-01-01)
Nesticodes rufipes is widely distributed in tropical and subtropical regions, being strongly associated with humans. However, few behavioral and ecological studies have investigated interspecific interactions between these ...

How population loss through habitat boundaries determines the dynamics of a predator-prey system
(Elsevier B.V., 2014-12-01)
The increased persistence of predator-prey systems when interactions are distributed through the space has been acknowledged by both empirical and theoretical studies. One salient feature of predator-prey interactions in ...
Consuming Costly Prey: Optimal Foraging and the Role of Compensatory Growth
(2021-03-18)
Some prey are exceptionally difficult to digest, and yet even non-specialized animals may consume them—why? Durophagy, the consumption of hard-shelled prey, is thought to require special adaptations for crushing or digesting ...
