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 model was particularly inspired by the work of Italian physicist Vito Volterra, who had developed his predator-prey equations based on observations of fish populations in the Adriatic Sea during World War I. Volterra's work showed that during the war, when fishing was reduced due to military activities, the proportion of predator fish ...
Examples include predator-prey competition and host-parasite co-evolution, as well as mutualism. Evolutionary game models have been created for pairwise and multi-species coevolutionary systems. [58] The general dynamic differs between competitive systems and mutualistic systems.
In this model, if e < m, the steady state value of p is 1 – (e/m) while in the other case, all the patches will eventually be left empty. This model may be made more complex by addition of another species in several different ways, including but not limited to game theoretic approaches, predator–prey interactions, etc.
The solution to these equations in the simple one-predator species, one-prey species model is a stable linked oscillation of population levels for both predator and prey. However, when time lags between respective population growths are modeled, these oscillations will tend to amplify, eventually leading to extinction of both species.

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.
Asymmetric games are frequently used to model mate choice (sexual selection) [36] or parent-offspring interactions. [ 57 ] [ 58 ] [ 59 ] [ 53 ] Asymmetric games are also used to model interspecific interactions such as predator-prey, [ 60 ] host-parasite [ 61 ] or plant-pollinator signalling. [ 62 ]
