The general theory of species abundance distributions
Abstract. A central issue in ecology today is that of the factors determining the relative abundance of species within a natural community. The proper application of the principles of statistical physics to the problem of species abundance distributions (SADs) has enabled us to identify the fundamental ecological principles responsible for the near universal features observed. These principles ...
متن کاملMissing the rarest: is the positive interspecific abundance-distribution relationship a truly general macroecological pattern?
Lepidopterists have long acknowledged that many uncommon butterfly species can be extremely abundant in suitable locations. If this is generally true, it contradicts the general macroecological pattern of the positive interspecific relationship between abundance and distribution, i.e. locally abundant species are often geographically more widespread than locally rare species. Indeed, a negative...
متن کاملPredicting the species abundance distribution using a model food web.
A large number of models of the species abundance distribution (SAD) have been proposed, many of which are generically similar to the log-normal distribution, from which they are often indistinguishable when describing a given data set. Ecological data sets are necessarily incomplete samples of an ecosystem, subject to statistical noise, and cannot readily be combined to yield a closer approxim...
متن کاملThe implicit assumption of symmetry and the species abundance distribution.
Species abundance distributions (SADs) have played a historical role in the development of community ecology. They summarize information about the number and the relative abundance of the species encountered in a sample from a given community. For years ecologists have developed theory to characterize species abundance patterns, and the study of these patterns has received special attention in ...
