Species Abundance and Community Organization

Ecology, 1959
The prevalent conviction among ecologists that natural communities represent important and meaningful assemblages of organisms has prompted a diverse series of analyses. The present paper is an examination of some of the analyses as applied primarily to soil arthropods, with an explanation of some of the difficulties that have been encountered.

Species Abundances Across Spatial Scales

Science, 1999
William E. Kunin ([1][1]) investigated the effect of spatial scale on the abundance of scarce British plant species and concluded by asking whether his observed patterns hold across a wider range of species and scales, which would permit extrapolation of scale-area curves to estimate abundance ...

The relative abundance of species

1984
Ecologists have long recognized that species are not equally abundant, and that communities with similar species densities often differ in another way; the relative importance or abundance of the constituent species. Considerable effort has been expended in attempts to document differences and regularities in relative abundances, as an understanding of

Models for the logarithmic species abundance distributions

Theoretical Population Biology, 1974
Abstract Three models, developed by Karlin, McGregor and Ewens to describe evolving populations of selectively neutral genotypes, are shown to lead to various versions of Fisher's logarithmic series distribution for species abundance. Statistical inference procedures and measures of diversity which have been developed in one of the two contexts are ...
