Gause’s Principle, also known as the competitive exclusion principle or Gause’s law, is a fundamental concept in ecology that describes the competition between species for limited resources. It states that two species that compete for the same resources cannot coexist in the long term at constant population values. When one species has even a slight … Read more

The history of the Lotka-Volterra predator-prey model can be traced back to the early 20th century. Alfred J. Lotka, an American mathematician and biophysicist, first proposed the model in 1910 in the context of autocatalytic chemical reactions.
