There is a need to understand how alteration of physical processes on the Rio Grande River have impacted aquatic biota and their habitats, and a need to predict potential future effects of climate change on biotic resources in order to prescribe research and management activities that will enhance conservation of aquatic species. We propose a project with the goal of developing monitoring recommendations and identifying research needs for aquatic ecological resources in the Big Bend region of the Rio Grande. This goal will be targeted by synthesizing and analyzing available data and literature for aquatic species in the project region. In particular, we will work to develop time series of abundance and population...

**Executive Summary: **The Big Bend reach of the Rio Grande is an important region for binational collaboration on ecosystem management and restoration. The river is well protected from further development as a national wild and scenic river and by national and state parks on both sides of the border, but has been degraded over time primarily by altered hydrology, water quality degradation, and non-native species impacts. The success of future restoration and management efforts depend on a fuller understanding of the linkages between physical and chemical processes and biotic communities. A robust monitoring program in the region and targeted research are needed to supply this understanding. In this report, we synthesize...
