1. Dams on large rivers alter hydrodynamics, reduce seasonal variability and environmental heterogeneity, have significant effects river ecology. They produce less diverse environments the community composition. Knowledge about of dams functional aspects zooplankton communities is scarce. Thus, our main goal was to investigate how Tocantins River in central Brazil changed after implementation Estreito hydroelectric power plant dam. We explored relationships taxonomic beta diversity...
<title>Abstract</title> Reservoirs transform the physical, biological and chemical characteristics of rivers, altering their flow dynamics availability nutrients. After a river is dammed, species composition in reservoir its tributaries tend to change response new conditions which are generated. This work investigates tributary rivers sites along main channel Tocantins River’s middle course. The study was conducted between 2009 2013 pre- post-dam periods evaluate effects dam on...
<title>Abstract</title> Research on hydroclimatic variations explains the relationships between water masses and global climate factors. Climate change causes changes in river flow regimes impacts ecosystems, economy, society. In this study, we characterized hydroclimatology of seven reservoirs Tocantins River, along 1,500 km during more than 12 years sampling, where analyzed climatic variables such as precipitation, solar radiation, net evaporation, air temperature, addition to hydrological...
