Use of Abundance of One Species as a Surrogate for Abundance of Others
Conservation Biology, 2010Abstract: Indicator species concepts have a long history in conservation biology. Arguments in favor of these approaches generally stress expediency and assume efficacy. We tested the premise that the abundance patterns of one species can be used to infer those of other species.

Tropical forests are recognized worldwide for providing ecosystem services that contribute greatly to biodiversity and ecosystem functioning. In this study, we hypothesize that tree species abundance distribution is determined by the commonness-rarity ...

Percolation Theory for the Distribution and Abundance of Species
Physical Review Letters, 2003We develop and test new models that unify the mathematical relationships among the abundance of a species, the spatial dispersion of the species, the number of patches occupied by the species, the edge length of the occupied patches, and the scale on which the distribution of species is mapped. The models predict that species distributions will exhibit

Abstract How many individuals of each species are there in a given community, and why? These questions, which lie at the heart of ecology, continue to motivate much ecological research. In this chapter one approach to answering these questions will be considered, i.e. the detection and interpretation of patterns of species abundance that

On the Distribution and Abundance of Species
Science, 1999Harte et al . ([1][1]) assumed the probability rule: if a species occurs in an area A , then the probability that it occurs in half of that area is a constant, a , independent of area A , satisfying 0.5 ≤ a ≤ 1. From this rule, Harte et al .

The form of species-abundance distributions
Journal of Theoretical Biology, 1980Abstract Small, isolated communities in harsh environments are sometimes found to contain many, very rare species together with a few, extremely abundant ones. The species-abundance distribution (frequencies of species vs. abundance levels) drops rapidly from an initial peak to an elongated tail.

Self-Similarity in the Distribution and Abundance of Species
Science, 1999If the fraction of species in area A that are also found in one-half of that area is independent of A , the distribution of species is self-similar and a number of observed patterns in ecology, including the widely cited species-area relationship connecting species richness to censused area ...

On the Relative Abundance of Species
Ecology, 1969When data are collected so that they can be treated as coming from a variety of sample sizes, it is possible to use the same data to test the effect of altering sample size on the fit to any model. The method is applied to nonpredatory soil mites and their fit to the "broken—stick" model of MacArthur. It is found that by choosing a quadrat size of 4 in.

A statistical theory for sampling species abundances
Ecology Letters, 2007AbstractThe 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 ...
