other populations and represents an important component of the evolutionary uses the criteria of Evolutionarily Significant Unit (ESU) (Waples 1991), i.e.,

This term can apply to any species, subspecies, geographic race, or population. Often the term species is used rather than ESU, even when an ESU is more technically considered a subspecies or variety rather Evolutionarily Significant Units Biodiversity conservation efforts tradition-ally focus on maintaining one or more mini-mum viable populations (MVP) of a focal taxon that, in theory, should persist on ecological time scales (Shaffer 1981). However, the past decade has seen an increased emphasis on conserving population-level genetic diversity To cite this article: L. P. Casacci, F. Barbero & E.

Pacific salmon recovery planning and the Salmonid Watershed Analysis Model (SWAM): a broad-scale tool for assisting in the development of habitat recovery plans. However, because multidisciplinary studies that evaluate the biodiversity within cycad species are almost non-existent intraspecific evolutionarily significant units (ESUs) have not been considered when making conservation plans. Evolutionärt betydande enhet - Evolutionarily significant unit Från Wikipedia, den fria encyklopedin En evolutionärt signifikant enhet ( ESU ) är en population av organismer som anses vara distinkta för bevarandeändamål . This dataset includes the boundaries evolutionarily significant units (ESUs) of salmon on the West Coast of the United States of America. 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. Evolutionarily Significant Unit (ESU) Reconsider the ESU interim policy on the use of propagation.

Two of these putative historical groupings were found to be genetically similar to extant evolutionarily significant units (ESUs) in the Okanogan and Wenatchee Rivers (pairwise FST = 0.004 and 0.002, respectively), and assignment tests were able to allocate 77% of the fish in these two historical groupings to the contemporary Okanogan River and Lake Wenatchee ESUs.

The National Marine Fisheries Service's (NMFS) evaluation of declining coho salmon abundance and productivity, as well as range reductions and diminished life-history diversity, supported the decision to list the Southern Oregon/Northern California Coast (SONCC) Evolutionarily Significant Unit (ESU) of coho salmon as a threatened species under The Evolutionarily Significant Unit (ESU), first conceptualised by Ryder in 1986, may offer some answer. Several definitions have been proposed for the ESU, but all make reference to units “whose divergence can be measured or evaluated by putting differential emphasis on the role of evolutionary forces at varied temporal scales”.

The Sacramento River winter-run evolutionarily significant unit (called an "ESU") of Chinook salmon is one of NOAA Fisheries' Species in the Spotlight. This initiative is a concerted, agency-wide effort launched in 2015 to spotlight and save the most highly at-risk marine species. The Evolutionarily Significant Unit (ESU), first conceptualised by Ryder in 1986, may offer some answer. Several definitions have been proposed for the ESU, but all make reference to units “whose For a given set of populations we cannot predict future outcomes, but we can make inferences about the evolutionary past. Thus, the term `significant' in ESU should be seen as a recognition that the set of populations has been historically isolated and, accordingly, is likely to have a distinct potential.

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.
