GOING WITH THE FLOW: THE ECOLOGICAL LINKAGES OF NEOTROPICAL FISHES TO HYDROLOGY
The Neotropics has numerous large river systems and the highest diversity of freshwater fishes on Earth. Flow characteristics of these rivers are a factor that has been linked to life cycle and ecology of many freshwater fishes. Human activities and their consequences, such as climate change, infrastructure development, and land use change, are altering the natural hydrology of Neotropical rivers. Hydrologic alterations also could disrupt the life cycles and ecological linkages of fishes to river flows. To quantify the ecological implications of changing hydrology on fish, a comprehensive understanding of relationships between hydrology and ecology is needed. We did a systematic review of the literature to answer: What are the relationships between the natural flow regime and the ecology of fishes in major Neotropical river systems? Our preliminary results returned >1500 papers published since 1945. Research has focused mainly in the Amazon (36%) and Parana (21%) basins. Using a text-mining approach, we identified the linkages of flow characteristics with reproduction, feeding, growth, and species. Our results could help inform new research and the decision-making process for management and conservation in the region in light of ongoing landscape and river alterations.
