Recovery of a marine keystone predator transforms terrestrial predator-prey dynamics. [PDF]
Proc Natl Acad Sci U S A, 2023 Significance While there has been much effort to understand how sea otter recovery transforms nearshore ecosystems, the effects on terrestrial systems have remained uninvestigated.

Bacterial predator-prey dynamics in microscale patchy landscapes. [PDF]
Proc Biol Sci, 2016 Soil is a microenvironment with a fragmented (patchy) spatial structure in which many bacterial species interact. Here, we explore the interaction between the predatory bacterium Bdellovibrio bacteriovorus and its prey Escherichia coli in microfabricated landscapes.

Barrier-mediated predator-prey dynamics [PDF]
EPL (Europhysics Letters), 2021 The survival chance of a prey chased by a predator depends not only on their relative speeds but importantly also on the local environment they have to face.

A synthetic Escherichia coli predator–prey ecosystem [PDF]
Molecular Systems Biology, 2008 We have constructed a synthetic ecosystem consisting of two Escherichia coli populations, which communicate bi‐directionally through quorum sensing and regulate each other's gene expression and survival via engineered gene circuits.

F1000Research, 2013 Heterogeneity among prey in their susceptibility to predation is a potentially important stabilizer of predator-prey interactions, reducing the magnitude of population oscillations and enhancing total prey population abundance.

Does sex-selective predation stabilize or destabilize predator-prey dynamics? [PDF]
PLoS ONE, 2008 Little is known about the impact of prey sexual dimorphism on predator-prey dynamics and the impact of sex-selective harvesting and trophy hunting on long-term stability of exploited populations.We review the quantitative evidence for sex-selective ...

Pattern Dynamics in a Spatial Predator-Prey System with Allee Effect [PDF]
Abstract and Applied Analysis, 2013 We investigate the spatial dynamics of a predator-prey system with Allee effect. By using bifurcation analysis, the exact Turing domain is found in the parameters space.

Characterization of predator-prey dynamics, using the evolution of free energy in plasma turbulence [PDF]
, 2012 A simple dynamical cascade model for the evolution of free energy is considered in the context of gyrokinetic formalism. It is noted that the dynamics of free energy, that characterize plasma micro-turbulence in magnetic fusion devices, exhibit a ...

Mathematics Open, 2023 During smart anti-predator adaptations, preys use their size, fleeing capability and herd in their evolutionary tug-of-war with the predators. Predator–prey ecology is teeming with such examples where predators can be defeated or even killed by the group

Predator discrimination of prey promotes the predator-mediated coexistence of prey species
Royal Society Open Science, 2022 The predator discrimination of prey can affect predation intensity and the prey density dependence of predators, which has the potential to alter the coexistence of prey species.
