Ecology and Evolution, 2020 Predation is a pervasive force that structures food webs and directly influences ecosystem functioning. The relative body sizes of predators and prey may be an important determinant of interaction strengths.

Altruistic Duality in Evolutionary Game Theory
, 2003 A game-theoretic model of social preference and enlightened self-interest is formulated. Existence of symmetry and duality in the game matrices with altruistic social preference is revealed.

Prey–Predator Communication: For Your Sensors Only [PDF]
Current Biology, 2007 Prey have evolved myriad strategies to escape predation. Ground squirrels tailor their defensive signals to the predator at hand and use infrared warning signals in response to heat-sensitive rattlesnakes.

Complexity in a prey-predator model [PDF]
Revue Africaine de Recherche en Informatique et Mathématiques Appliquées, 2008 In this paper we consider a predator-prey model given by a reaction-diffusion system. It incorporates the Holling-type-II and a modified Leslie-Gower functional response. We focus on qualitaive analysis, bifurcation mecanisms and patterns formation. Nous considérons un modèle proie-prédateur exprimé sous forme de système de réaction diffusion.

Advanced Materials Interfaces, EarlyView.MOFs awaken graphene. MOF‐assisted ultrafast laser writing patterns porous laser‐induced graphene with CuO‐active nanodomains, creating an aptamer‐ready interface for small‐molecule capture. Coupled to an extended‐gate FET, the hybrid converts subtle biochemical binding into a clear electrical signal for resilient cortisol sensing in aqueous media ...

A two-patch prey-predator model with predator dispersal driven by the predation strength
Mathematical Biosciences and Engineering, 2017 Foraging movements of predator play an important role in population dynamics of prey-predator systems, which have been considered as mechanisms that contribute to spatial self-organization of prey and predator.
