TLDR
It was suggested that wind, via wave action, may be a critical determinant of both the qualitative and quantitative aspects of biocoenotic structure in large bodies of fresh water.

TLDR
Several “indices of non-randomness” are compared with regard to their dependence on sample number, sample size and density and a new coefficientC x is proposed for use with positively contagious distributions.
