Scientific Reports, 2021 Understanding the factors governing predation remains a top priority in ecology. Using a dragonfly nymph-tadpole system, we experimentally varied predator density, prey density, and prey species ratio to investigate: (i) whether predator interference ...

Evolution in predator–prey systems
Stochastic Processes and their Applications, 2010 We study the adaptive dynamics of predator-prey systems modeled by a dynamical system in which the traits of predators and prey are allowed to evolve by small mutations. When only the prey are allowed to evolve, and the size of the mutational change tends to 0, the system does not exhibit long term prey coexistence and the trait of the resident prey ...

Optimal Harvesting for a Predator–Prey Metapopulation [PDF]
Bulletin of Mathematical Biology, 1998 The authors investigate a deterministic, discrete-time, two-patch predator-prey model with harvesting. The model has a similar structure as the one introduced by \textit{G.N. Tuck} and \textit{H.P. Possingham} [Bull. Math. Biol. 56, No. 1, 107-127 (1994; Zbl 0789.92024)].

Role reversal in a predator–prey interaction [PDF]
Royal Society Open Science, 2014 Predator–prey relationships are one of the most studied interactions in population ecology. However, little attention has been paid to the possibility of role exchange between species, despite firm field evidence of such phenomena in nature. In this paper, we build a mathematical model capable of reproducing the main phenomenological features of role ...

Attraction and Avoidance between Predators and Prey at Wildlife Crossings on Roads
Diversity, 2020 Wildlife passages are currently built at roads and railway lines to re-establish connectivity. However, little is known about whether predator-prey interactions may reduce the effectiveness of the crossing structures.

Journal of Applied Mathematics, 2022 In this paper, we present and analyze predator-prey system where prey population is linearly harvested and affected by fear and the prey population has grown logistically in the absence of predators.

Prey and predator density‐dependent interactions under different water volumes
Ecology and Evolution, 2021 Predation is a critical ecological process that directly and indirectly mediates population stabilities, as well as ecosystem structure and function. The strength of interactions between predators and prey may be mediated by multiple density dependences ...
