Neutralism (a term introduced by Eugene Odum) [22] describes the relationship between two species that interact but do not affect each other. Examples of true neutralism are virtually impossible to prove; the term is in practice used to describe situations where interactions are negligible or insignificant. [23] [24]
The Kendall rank coefficient is often used as a test statistic in a statistical hypothesis test to establish whether two variables may be regarded as statistically dependent. This test is non-parametric , as it does not rely on any assumptions on the distributions of X or Y or the distribution of ( X , Y ).
Biological applications of bifurcation theory provide a framework for understanding the behavior of biological networks modeled as dynamical systems. In the context of a biological system, bifurcation theory describes how small changes in an input parameter can cause a bifurcation or qualitative change in the behavior of the system.

Inclusive fitness theory (and the related kin selection theory) are general theories in evolutionary biology that propose a method to understand the evolution of social behaviours in organisms. While various ideas related to these theories have been influential in the study of the social behaviour of non-human organisms, their application to ...
The theory was popular in the 1970s and 1980s, when it was used as a heuristic device, but lost importance in the early 1990s, when it was criticized by several empirical studies. [ 5 ] [ 6 ] A life-history paradigm has replaced the r / K selection paradigm, but continues to incorporate its important themes as a subset of life history theory. [ 7 ]

By stotting (also called pronking), a springbok (Antidorcas marsupialis) signals honestly to predators that it is young, fit, and not worth chasing.. Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species.
