In this paper, we consider positive solutions of a predator-prey model with diffusion and under homogeneous Dirichlet boundary conditions. It turns out that a certain parameter m in this model plays a ...

Spatially explicit models are constructed for predator dispersal, predator-prey interactions, and prey dispersal and population dynamics in a system where the appropriate spatial and temporal scales ...

Predator-prey cycles are among the fundamental phenomena of ecological systems: the population sizes of predators and their prey, for instance foxes and hares, are frequently subject to regular ...

Predator Prey models are used to measure the interaction between species in an environment. This project investigates predator/prey equations and provides a pictorial interface in Scratch for ...

Marine food webs are highly complex. Until now, researchers have been unable to understand exactly how they are affected by climate change, overfishing and other threats. Scientists at the ...

In the 1920s, two mathematicians working on separate continents proposed the same set of mathematical equations for describing population growth and decline in biological systems. Alfred Lotka, a ...

Predator Prey models are used to measure the interaction between species in an environment. This project investigates predator/prey equations and provides a pictorial interface in Scratch for ...
