EcoSim is an individual-based predator-prey ecosystem simulation in which agents can evolve. It has been designed to investigate several broad ecological questions, as well as long-term evolutionary patterns and processes such as speciation and macroevolution.
The Lotka–Volterra predator-prey model makes a number of assumptions about the environment and biology of the predator and prey populations: [5] The prey population finds ample food at all times. The food supply of the predator population depends entirely on the size of the prey population.
The aim of Huffaker’s 1958 experiment was to “shed light upon the fundamental nature of predator–prey interaction” [2] and to “establish an ecosystem in which a predatory and a prey species could continue living together so that the phenomena associated with their interactions could be studied in detail”. [3]
It models the population growth of a predator/prey system over time. It has the following characteristics: There are two breeds of turtles, called sheep and wolves. Sheep and wolves move randomly and have limited energy. Wolves and sheep lose energy by moving. If a wolf or sheep has zero energy, it dies. Sheep gain energy by eating grass.
Often a computer screen simulation program is used on animals, such as birds of prey, to detect prey selection. [15] Another type looks into how apostatic selection can act on the predator as well as the prey, as predator plumage polymorphism can also be influenced by apostatic selection.

Dan Trachtenberg, director of 2022’s straight-to-streaming, Emmy-winning Prey movie, has another two Predator projects on the horizon — including a top-secret one that might again debut on Hulu.
where N is the prey and P is the predator population sizes, r is the rate for prey growth, taken to be exponential in the absence of any predators, α is the prey mortality rate for per-capita predation (also called ‘attack rate’), c is the efficiency of conversion from prey to predator, and d is the exponential death rate for predators in ...
