Competition occurs when the interaction of two organisms has an adverse effect on both. The primary models for competition are based on the Lotka-Volterra equations. Replacement series experiments are a standard approach to evaluating the competitive relationships of two or more species. Measures of niche overlap, such as similarity indices, are often used as initial indicators of competition although they are recognized not to be true measures of competition. The probability of a species being present may be related to environmental variables and the presence of other species using logistic regression.
