Studies on beta diversity across different spatial scales can yield insight into the ecological factors that shape communities and the mechanisms of maintenance and loss of diversity. The coastal rivers in southeast Brazil ...

Monthly samples were taken from April 1992 to March 1993 of fish assemblages present in six permanent lagoons and four ponds, fragmented from them during the drought period and during the terminal phases of desiccation, ...

Changes in richness, diversity, evenness and abundance of phytoplankton in relation to environmental variables and tributary entrances were studied along 30 km of the Parana River downstream Itaipu Reservoir. A high number ...

Riverine floodplains are among the most diverse and dynamic ecosystems, but river regulation measures have altered the natural hydrological regime threatening their ecological integrity. We compared spatial patterns of ...

Ecogeomorphology is an interdisciplinary approach to the study of river systems, and 26 one that integrates hydrology, geomorphology and ecology. Fluvial geomorphology 27 provides an initial starting point for characterizing ...
