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 ...
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 ...

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 ...

On certain new exact solutions of a diffusive predator-prey system
(2013-05-01)
We construct exact solutions for a system of two coupled nonlinear partial differential equations describing the spatio-temporal dynamics of a predator-prey system where the prey per capita growth rate is subject to the ...

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 ...
