A clarification of the meaning of the covariance of the community matrix is presented along with calculating equations for both the mean species covariance and the covariance of the row and column means. A brief discussion of α selection and its determination of the covariance is given, followed by table for determining the expected number of species in a community from a knowledge of mean α and cov α.
