A linear model is developed for species dissimilarity. The model, which potentially can be used in conjunction with any species dissimilarity index, is designed for data sets which involve both multiple species and multiple environmental variables. The total species dissimilarity is divided into components with 1 component being assigned to each environmental variable or interaction of environmental variables. Unbiased estimates for the variance of each component are provided.
