Abstract

Heip, C. (1976). On the relative abundance of natural populations. Biol. Jb. Dodonaea 44: 210-216

The constant and similar statistical variability shown by various aquatic populations is postulated to be a result of competition for space. When competition for space occurs, numbers of species should form a series of abundance in which two adjacent species differ by a factor which at closest packing is 1.27. This hypothesis is tested by comparing different communities where competition for space is expected to occur (marine phytoplankton) or not (brackish water copepods).
