Species-Abundance Relation and Diversity

1984
The scenic affluence of nature is attributable to the fact that most ecological communities contain a rich variety of biological species with widely differing abundances. Ecologists long have been interested in the distribution of abundances of species within a given area.

A statistical theory for sampling species abundances

Ecology Letters, 2007
AbstractThe pattern of species abundances is central to ecology. But direct measurements of species abundances at ecologically relevant scales are typically unfeasible. This limitation has motivated a long‐standing interest in the relationship between the abundance distribution in a large, regional community and the distribution observed in a small ...

Species-abundance distributions under colored environmental noise

Journal of Mathematical Biology, 2016
Natural communities at all spatiotemporal scales are subjected to a wide variety of environmental pressures, resulting in random changes in the demographic rates of species populations. Previous analyses have examined the effects of such environmental variance on the long-term growth rate and time to extinction of single populations, but studies of its

Species Abundance: Natural Regulation of Insular Variation

Science, 1963
Variation in numbers of land plant species on islands in the Galapagos Archipelago can be predicted on the basis of elevation, area of the adjacent island, distance from the nearest island, and distance from the center of the archipelago, but not on the basis of the area of the host island. Multiple linear regression (y = bx 1

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 ...
