They are defined as a population that is substantially reproductively isolated from cospecific populations and represents an important component in the evolutionary legacy of the species. Evolutionarily Significant Units of Rare Pygmy Sunfishes (Genus Elassoma) J. M. QUATTRO, W. J. JONES, AND F. C. ROHDE Mitochondrial and nuclear gene variation is described from populations repre-senting the range of two species of rare pygmy sunfishes, Elassoma boehlkei and Elassoma okatie, in the Carolinas. Evolution is change in the heritable characteristics of biological populations over successive generations. These characteristics are the expressions of genes that are passed on from parent to offspring during reproduction. Different characteristics tend to exist within any given population as a result of mutation, genetic recombination and other sources of genetic variation.

A classification of populations that have substantial reproductive isolation which has led to adaptive differences so that the population represents a significant evolutionary component of the species. Evolutionary significant units have also been classified as populations that exhibit reciprocal monophyly and no recent gene flow. At the center of both tasks over the past decade and a half has been the concept of the evolutionarily significant unit (ESU)—roughly speaking, an important chunk of a species. Almost since the term first appeared in the scientific literature, an intense debate has raged over how, exactly, to define this basic unit of conservation—especially with reference to the ESA in the United States.

An evolutionarily significant unit, or ESU, of Pacific salmon is considered to be a "distinct population segment" and thus a "species" under the Endangered Species Act. Chinook salmon, Chum salmon, Coho salmon, Pink salmon, Sockeye salmon, and steelhead are all included in the dataset.

Delineating ESUs is important when considering conservation action.
