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.

The unifying theme of the NMFS species policy is the desire to identify and conserve important genetic resources in nature, thus allowing the dynamic process of evolutioa to continue largely unaffected by human factors. of Evolutionarily Significant Units Paul McElhany, Mary H.

Bjorkstedt* Northwest Fisheries Science Center Conservation Biology Division 2725 Montlake Boulevard East Seattle, Washington 98112-2097 *Southwest Fisheries Science Center Santa Cruz/Tiburon Laboratory, Salmon Analysis Branch An evolutionarily significant unit is a population of organisms that is considered distinct for purposes of conservation. Delineating ESUs is important when considering conservation action. 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).

Evolutionarily significant unit

Evolution occurs when evolutionary processes such as natural selection and genetic drift act on this variation, resulting Evolutionarily Significant Units, Distinct Population Segments, and the Endangered Species Act: Reply to Pennock and Dimmick. ROBIN S. WAPLES.

Introduction text, evolutionarily significant units (ESUs) represent ideal targets for conservation because they contain the raw material for future evo-lutionary adaptations (Bowen & Roman, 2005; Fraser & Bernatchez, 2001; Pauls et al., 2013). Thus, population viability evaluations should begin with the challenging task of delineating these intraspecific units 2014-07-01 · Recovery Plan for The Evolutionarily Significant Units of Sacramento River Winter-run Chinook Salmon and Central Valley Spring-run Chinook Salmon and the DPS of California Central Valley Steelhead.

the Act if the population represents an evolutionarily significant unit (ESU) of the biological species. An ESU is a population (or group of populations) that (1) is substantially reproductively isolated from other conspe- cific population units, and (2) represents an important component in the evolutionary legacy of the species.

Evolutionarily Significant Unit (ESU). 1.2.1 Background on Listing Determinations Under the ESA, a species, subspecies, or a distinct population segment (DPS) may be listed as threatened or endangered. To identify the proper taxonomic unit for consideration in an ESA

An ESU is a population (or group of populations) that (1) is substantially reproductively isolated from other conspe- cific population units, and (2) represents an important component in the evolutionary legacy of the species. by Cate Moore on March 10, 2013. According to the National Marine Fisheries Service (NMFS, NOAA Fisheries) a population must satisfy two criteria to be considered an ESU: (1) it must be substantially reproductively isolated from other conspecific population units; and (2) it must represent an important component in the evolutionary legacy of a species. 69 Fed. Reg. at 31355. Part One sets the theme of the book by focusing on the Evolutionarily Significant Unit (ESU), a concept introduced by the National Marine Fisheries Service (NMFS) in 1991 for identification of distinct population segments in Pacific salmon.

Delineating ESUs is important when considering conservat The Designatable Unit, unlike the Evolutionarily Significant Unit, arises in the process of determining status as a device for reporting status and not as a concept for subspecific systematics. 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. Many translated example sentences containing "evolutionarily significant unit" – German-English dictionary and search engine for German translations. 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”.

This term can apply to any species, subspecies, geographic race, or population. 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. Evolutionary significant units have also been classified as populations that exhibit reciprocal monophyly and no recent gene flow.
