Flow‐mediated predator–prey dynamics influence fish populations in a tropical river
Freshwater Biology, 20191. Predator–prey interactions are an inherently local-scale phenomenon, but the intensity of these interactions can be mediated by abiotic conditions that can exert a multi-scaled influence through space and time.

DYNAMICS OF MODIFIED PREDATOR-PREY MODELS
International Journal of Bifurcation and Chaos, 2010Besides being structurally unstable, the Lotka–Volterra predator-prey model has another shortcoming due to the invalidity of the principle of mass action when the populations are very small. This leads to extremely large populations recovering from unrealistically small ones.

Inducible defense destabilizes predator-prey dynamics: the importance of multiple predators
Oikos, 2018Phenotypic plasticity in prey can have a dramatic impact on predator–prey dynamics, e.g. by inducible defense against temporally varying levels of predation.

Breeding Suppression and Predator-Prey Dynamics
Ecology, 2000In a biotic environment, current reproduction will affect future population sizes, but these future changes may also affect the optimality of current reproductive decisions. We investigate the dynamics of predator–prey cycles if both predators and prey respond to each other’s (and their own) population density by adjusting their breeding effort.

COEVOLUTIONARY DYNAMICS OF PREDATOR-PREY INTERACTIONS
International Journal of Biomathematics, 2012In this paper, with the method of adaptive dynamics, we investigate the coevolution of phenotypic traits of predator and prey species. The evolutionary model is constructed from a deterministic approximation of the underlying stochastic ecological processes. Firstly, we investigate the ecological and evolutionary conditions that allow for continuously

Group formation stabilizes predator–prey dynamics
Nature, 2007Theoretical ecology is largely founded on the principle of mass action, in which uncoordinated populations of predators and prey move in a random and well-mixed fashion across a featureless landscape. The conceptual core of this body of theory is the functional response, predicting the rate of prey consumption by individual predators as a function of ...

Life‐history traits buffer against heat wave effects on predator–prey dynamics in zooplankton
Global Change Biology, 2018In addition to an increase in mean temperature, extreme climatic events, such as heat waves, are predicted to increase in frequency and intensity with climate change, which are likely to affect organism interactions, seasonal succession, and resting ...

Dynamics of a Predator-Prey Model
SIAM Journal on Applied Mathematics, 1999Summary: We describe the bifurcation diagram of limit cycles that appear in the first realistic quadrant of the predator-prey model proposed by \textit{R.M. May} [ Stability and complexity in model ecosystems. (1974)]. In particular, we give a qualitative description of the bifurcation curve when two limit cycles collapse on a semistable limit cycle ...

Optimal Foraging and Predator–Prey Dynamics, II
Theoretical Population Biology, 1999In this paper we consider one-predator-two-prey population dynamics described by a control system. We study and compare conditions for permanence of the system for three types of predator feeding behaviors: (i) specialized feeding on the more profitable prey type, (ii) generalized feeding on both prey types, and (iii) optimal foraging behavior. We show
