Potential impact of small hydroelectric power plants on river biota: a case study on macroinvertebrates associated to basaltic knickzones

Braz. j. biol; 79 (4), 2019
Abstract Small hydroelectric power plants (SHP) have been considered as an alternative for the generation of electricity with reduced environmental impacts. Nevertheless, no studies have addressed changes in a particular kind of river macrohabitat commonly affected by SHPs, the knickzones. This study ai...

Reservoir longitudinal gradient promotes ordered losses on diversity and density of Ephemeroptera community

Braz. j. biol; 78 (4), 2018
Abstract Reservoir operations alter, eliminate or restrain the natural hydrologic cycles. Biotic community has become subject to these non-cyclic events, responding by reducing the species diversity. Ephemeroptera species present distinct responses to environmental deterioration such that poses this asse...

Rev. biol. trop; 65 (1), 2017
ResumenEl bosque tropical seco (BTS) de la Península de Yucatán ha sido manejado por siglos, pero la relación del efecto del manejo sobre la diversidad de árboles no ha sido completamente entendida. El objetivo de este estudio fue evaluar el efecto del manejo forestal (aclareos, aprovechamiento y enr...

Using indigenous knowledge to link hyper-temporal land cover mapping with land use in the Venezuelan Amazon: "The Forest Pulse"

Rev. biol. trop; 64 (4), 2016
Abstract:Remote sensing and traditional ecological knowledge (TEK) can be combined to advance conservation of remote tropical regions, e.g. Amazonia, where intensive in situ surveys are often not possible. Integrating TEK into monitoring and management of these areas allows for community participation, a...
