Can fishways restore river connectivity? A case study using β diversity as a method of assessmentPassagens para peixes podem restaurar a conectividade fluvial? Um estudo de caso usando diversidade β como método de avaliação
(2018-01-01)
Aim: β diversity was used as an indicator to test the hypothesis that a fishway can increase river connectivity, as a reduction in the value of this metric indicates greater similarity among fish assemblages. Methods: ...

Dispersal of fish eggs and larvae in a cascade of small hydropower plants with fish ladders
(Springer, 2020-10-10)
This study was conducted to investigate fish eggs and larvae dispersal in a river stretch influenced by small hydropower plants in Southeast Brazil. The main hypothesis is that the downstream dispersal of free-flowing eggs ...
Análise da estrutura genética populacional de duas espécies de Characiformes (Pygocentrus nattereri e Potamorhina latior) na região da bacia do Rio Madeira, Rondônia
(Universidade Estadual Paulista (Unesp), 2013-02-27)
The order Characiformes gathers approximately 1,670 freshwater species, of which at least 1,300 occur in Brazil. To date relatively few genetic studies have been conducted with species of this group, particularly in the ...
When roads cross streams: fish assemblage responses to fluvial fragmentation in lowland Amazonian streams
(Soc Brasileira Ictiologia, 2020-01-01)
Roads affect biodiversity by increasing mortality rates, habitat loss, and natural landscape fragmentation. Poorly installed culverts can impound streams, changing the environmental conditions, and affecting aquatic ...

(Universidade Federal de Santa MariaBrasilGeociênciasUFSMPrograma de Pós-Graduação em Geografia e GeociênciasCentro de Ciências Naturais e Exatas, 2018-11-26)
This research has the perspective of providing subsidies for a better planning for future actions that involve the management of water resources as well as help in the maintenance of artificial reservoirs, since the formation ...
Reproductive aspects of the prawn macrobrachium amazonicum in a continental population living downstream of a hydroelectric damAspectos reprodutivos do camarão dulcícola macrobrachium amazonicum em uma população vivendo a jusante da barragem de uma usina hidrelétrica
(2020-01-01)
The migratory behavior of females of the freshwater prawn Macrobrachium amazonicum (Heller, 1862) can indicate a strategy that optimizes the population establishment. With this idea in mind, we evaluated the reproductive ...
Reservoir design and operation: Effects on aquatic biota-a case study of planktonic copepods
(2013-03-20)
Copepod assemblages from two cascade reservoirs were analyzed during two consecutive years. The upstream reservoir (Chavantes) is a storage system with a high water retention time (WRT of 400 days), and the downstream one ...
