We present moment orientated tests of fit for some discrete distributions used in ecological applications. The distributions covered are the Poisson, negative binomial, zero-truncated Poisson, logarithmic, zero-inflated Poisson, binomial, beta-binomial, geometric, Neyman Type A and the bivariate Poisson. Each distribution is illustrated by reference to ecological data. The tests of fit we give are often more powerful than traditional chi-squared tests.
