TITLE:

Population genetic structure of dourado Salminus brasiliensis (Cuvier, 1816) segregated by dams on the Rio Grande, MG

KEY WORDS:

Genetic diversity, population genetics, conservation, hydroelectric plants

PAGES: 13
BIG AREA: Ciências Biológicas
AREA: Ecologia
SUMMARY:

The Rio Grande along its course has 12 dams of hydroelectric plants and the construction of these plants in cascade caused a great impact on the river, resulting in few significant lotic stretches implying a drastic environmental alteration. Which negatively influences communities, interrupts migratory routes and leads to a decrease in spawning sites, preventing the generation of new environmental conditions for aquatic biota, which harms migratory routes, the biogenic capacity of the system, as well as the availability of food and shelter for juvenile fish. In addition to the physical impediment that dams make it impossible for larval drift, they lead to an increase in larval mortality. The dourado Salminus brasiliensis (Cuvier, 1816) is a migratory fish and the schools perform long upward migrations during spawning, other studies have already pointed out divergences in the populations after genetic analyses. Microsatellite markers constitute a tool that can be applied to questions of elucidation and inference about the genetic structure of the dourado population and the possible impacts suffered by their populations, helping in management actions aimed at reducing anthropic impacts and mitigation measures for the conservation of the species. Thus, the objective of this work is to analyze the structure of the genetic diversity of Salminus brasiliensis, in the context of the upper rio Grande basin system, analyzing the population genetic structure of microsatellites in dourados, testing whether there is an association of genetic structure with potential physical segregation caused by dams of hydroelectric plants.
