Predator – Prey Relationships 933 P Predator – Prey Relationships
Most marine mammals are predators, but some are also preyed upon by other species. Theoretically, the interaction between marine mammals and their prey infl uences the structure and dynamics of marine ecosystems. Similarly, predators and prey have shaped each other’s behaviors, physiologies, morphologies, and life-history strategies. However, there is little empirical evidence of these infl uen...
متن کاملPredator hunting mode and habitat domain alter nonconsumptive effects in predator-prey interactions.
Predators can affect prey populations through changes in traits that reduce predation risk. These trait changes (nonconsumptive effects, NCEs) can be energetically costly and cause reduced prey activity, growth, fecundity, and survival. The strength of nonconsumptive effects may vary with two functional characteristics of predators: hunting mode (actively hunting, sit-and-pursue, sit-and-wait) ...
متن کاملThe stochastic interactions between predator and prey under Markovian switching: competitive interaction between multiple prey
In this paper, a class of predator-prey model with prey competition is proposed, in which the interactions of predation between predator and prey are randomised and subsequently evaluated under Markovian switching. By constructing appropriate Lyapunov functions and applying various analytical methods, sufficient conditions for the existence of unique global positive solution, stochastic permane...
متن کاملLIMITED GROWTH PREY MODEL AND PREDATOR MODEL USING HARVESTING
In this paper, we have proposed a study on controllability and optimal harvestingof a prey predator model and mathematical non linear formation of the equation equilibriumpoint of Routh harvest stability analysis. The problem of determining the optimal harvestpolicy is solved by invoking Pontryagin0s maximum principle dynamic optimization of theharvest policy is studied by taking the combined h...
متن کاملOcean Acidification Disrupts Prey Responses to Predator Cues but Not Net Prey Shell Growth in Concholepas concholepas (loco)
BACKGROUND Most research on Ocean Acidification (OA) has largely focused on the process of calcification and the physiological trade-offs employed by calcifying organisms to support the building of calcium carbonate structures. However, there is growing evidence that OA can also impact upon other key biological processes such as survival, growth and behaviour. On wave-swept rocky shores the abi...
