Reservoirs can have both positive and negative effects on differing fish species depending on the species concerned and reservoir morphology, flow regime, and basin location. We assessed the influence of limnological zones on the ichthyofauna of three large Neotropical reservoirs in two different river basins. We sampled fish through use...

Tropical dry forests are the most threatened forest type in the world yet a paucity of research about them stymies development of appropriate
conservation actions. The Paran~a River Basin has the most significant dry forest formations in the Cerrado biome of central Brazil
and is threatened by intense land conversion...
Over the last decade hydrologic monitoring efforts in the Upper Klamath Basin (UKB) of Oregon have increased in response to the continued strain on surface water and groundwater to meet competing biological and agricultural demands. The Oregon Water Resources Department (OWRD) increased its stream gaging network from three to ten...
In 2008 the U.S. Geological Survey began a Global Change study that evaluated the watershed scale response to climate change in selected basins across the United States. Fourteen basins for which the Precipitation Runoff Modeling System (PRMS) had been calibrated and evaluated were selected as study sites. PRMS is a...
With too many demands placed on too little water, the Klamath Basin and itsresidents - human and otherwise - are in dire need. There exists a significant opportunityfor mitigation in the purposeful conversion of seasonal wetlands to permanent wetlandsmanaged to increase baseline water storage levels in the Upper Basin. A...
Climate change will continue to profoundly affect water supply and aquatic ecosystems in the Pacific Northwest. Changes such as warmer air temperatures, increases in the proportion of winter rain versus snow, reduced spring snowpack, and earlier snowmelt all affect streamflow. The response to these climate impacts includes earlier runoff peaks,...
