In the ecological models of the previous chapters much attention is given to the dynamics of a single population. In contrast, in this chapter we concentrate on the dynamics of interspecies interactions. The two-species model consists of a predator population and a prey population. Both are present within a given area with a specified carrying capacity.

Stability and Hopf Bifurcation of a Delayed Prey-Predator Model with Disease in the Predator
International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2019Dealing with the epidemiological prey–predator is very important for us to understand the dynamical characteristics of population models. The existing literature has shown that disease introduction into the predator group can destabilize the established ...

Modeling the fear effect on a stochastic prey–predator system with additional food for the predator
Journal of Physics A: Mathematical and Theoretical, 2018In the present work we have studied a prey–predator model with logistic growth of the prey in the absence of the predator. We have also considered the fear effect and have investigated the impact of fear of the predator on prey when the predator is ...

Predation has been given many different definitions. For the purposes of this chapter, it is an interaction in which one free-living individual kills and derives resources from another organism. This definition includes finches that consume seeds but does not include fish that eat the siphons of clams that are unable to retract them quickly enough ...

Simple predator-prey swarming model
Physical Review E, 2010This paper describes an individual-based model for simulating the swarming behavior of prey in the presence of predators. Predators and prey are represented as agents that interact through radial force laws. The prey form swarms through attractive and repulsive forces.

All animals are either predators or prey and, in most cases, they are both. The interactions involved in attempting to eat and avoid being eaten have strong and wide-reaching influences across all facets of ecology, from individual phenotypic responses and population dynamics, to community interactions, and even to how we attempt to manage and conserve

Ecology is concerned with the interrelationships between organisms and their environment. Observations of ecosystems containing two species, one of whom (known as the prey) serves as a food source for the other (known as the predator), indicate that the populations of the two species show out-of-phase oscillatory behavior.

Predator-prey interactions play a central role in the behavior, ecology, and population biology of most taxa and are critical in community dynamics. For elasmobranchs, most studies focus only on their role as a predator. This is an important oversight, because most species are both predator and prey, at least for periods of their life.

Predator-prey interactions have been among the most intensively studied areas of aquatic biology during the past several decades. Investigations have focused particularly on theories of “optimal foraging,” which seeks to describe predator behavior [e.g., Charnov (1976), Werner and Hall (1974), and Pyke (1984)], and “predator mediated community ...

When species interact the population dynamics of each species is affected. In general, there is a whole web of interacting species, called trophic web, which makes for structurally complex communities We consider here systems involving two species. There are three main types of interaction: (i) When the growth rate of one population is decreased,
