From cues to signals: evolution of interspecific communication via aposematism and mimicry in a predator-prey system. [PDF]
PLoS ONE, 2014 Current theory suggests that many signaling systems evolved from preexisting cues. In aposematic systems, prey warning signals benefit both predator and prey. When the signal is highly beneficial, a third species often evolves to mimic the toxic species,

Invasion of a stream food web by a new top predator. [PDF]
, 1999 PhDA large predator, the nymph of the dragonfly Cordulegaster boltonii (Anisoptera) (Donovan), has recently invaded Broadstone Stream, an acid headwater in southern England.

Dynamics and pattern formation in diffusive predator-prey models with predator-axis
Electronic Journal of Differential Equations, 2020 We consider a three-species predator-prey system in which the predator has a stage structure and the prey moves to avoid the mature predator, which is called the predator-taxis.

Franklin OpenThe environmental carrying capacity plays a major role in population dynamics and is highly unpredictable in predator–prey relationships. In this study, we examine a predator–prey model with logistic growth rate and variable carrying capacity of prey ...

Effects of Behavioral Tactics of Predators on Dynamics of a Predator-Prey System
Advances in Mathematical Physics, 2014 A predator-prey model incorporating individual behavior is presented, where the predator-prey interaction is described by a classical Lotka-Volterra model with self-limiting prey; predators can use the behavioral tactics of rock-paper-scissors to dispute

Numerical convergence of a Telegraph Predator-Prey system
Semina: Ciências Exatas e Tecnológicas, 2022 Numerical convergence of a Telegraph Predator-Prey system is studied. This partial differential equation (PDE) system can describe various biological systems with reactive, diffusive, and delay effects.

Stability Analysis of a Patchy Predator–Prey Model with Fear Effect
Axioms, 2022 In this paper, a predator–prey model with fear effect and dispersal is proposed. Assume that only the prey migrates at a constant rate between patches and the migration of prey on each patch is faster than the time scale of local predator–prey ...

Coordinated Architectural and Chemical Reinforcement in the Crushing Mandible of a Soldier Termite
Advanced Functional Materials, EarlyView.The crushing mandible of a soldier termite withstands substantial biting loads despite lacking mineral. Its cuticle is partitioned: convex teeth pair hardness and zinc enrichment with aligned chitin fibers for contact durability, while stiffer concave regions between teeth carry bending loads.

Revisiting the spatiotemporal dynamics of a diffusive predator-prey system: An analytical approach
Results in Physics, 2023 This study investigates some analytic solutions and phase portraits to the diffusive predator-prey system in studying the spatiotemporal dynamics of a predator-prey community in ecology through an analytical approach and a qualitative theory of planar ...
