Warning signals and predator–prey coevolution [PDF]
Proceedings of the Royal Society of London. Series B: Biological Sciences, 2004 Theories of the evolution of warning signals are typically expressed using analytic and computational models, most of which attribute aspects of predator psychology as the key factors facilitating the evolution of warning signals. Sherratt provides a novel and promising perspective with a model that considers the coevolution of predator and prey ...

The importance of predator behaviour on risk to prey [PDF]
, 2008 Both predator and prey have evolved to maximise reproductive success by balancing food intake with risk. There has been a bias in predator-prey studies, where prey behaviour has been examined in detail, yet predators are assumed to follow simplistic ...

Stability analysis in generalist predator-prey dynamics with predator harvesting [PDF]
Computational Ecology and SoftwareThis paper seeks to explore the stability assessment of a generalist predator-prey system with predator harvesting. The study presents a model examining the dynamics between primary prey and predator, considering the existence of a generalist predator ...

Predator–prey interactions in the canopy [PDF]
Ecology and Evolution, 2020 AbstractSmall mammal abundances are frequently limited by resource availability, but predators can exert strong lethal (mortality) and nonlethal (e.g., nest abandonment) limitations. Artificially increasing resource availability for uncommon small mammals provides a unique opportunity to examine predator–prey interactions.

A MICROFOUNDATION OF PREDATOR‐PREY DYNAMICS [PDF]
Natural Resource Modeling, 2003 ABSTRACT. Predator‐prey relationships account for an important part of all interactions betweenspecies. In this paper we provide a microfoundation for such predator‐prey relations in afood chain. Basic entities of our analysis are representative organisms of species modeled similar to economic households.

Chemotactic predator-prey dynamics [PDF]
Physical Review E, 2011 A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa. Two dynamical states corresponding to catching and escaping are identified and it is shown that steady hunting is unstable.

Combining impact of velocity, fear and refuge for the predator–prey dynamics
Journal of Biological Dynamics, 2023 We develop a deterministic predator–prey compartmental model to investigate the impact of their velocities on their interactions. Prey hides in a refuge area and comes out of this area when predation pressure declines.

Go big or … don't? A field-based diet evaluation of freshwater piscivore and prey fish size relationships. [PDF]
PLoS ONE, 2018 Body size governs predator-prey interactions, which in turn structure populations, communities, and food webs. Understanding predator-prey size relationships is valuable from a theoretical perspective, in basic research, and for management applications ...

Numerical Simulation of Leslie-Gower Predator-Prey Model with Stage-Structure on Predator
Journal of Experimental Life Science, 2018 In this paper, we introduce Leslie-Gower predator-prey model with a stage-structure population on the predator. This model consists of two populations, that are prey and predator populations. Here, we divide predator into two stages.
