The Geological Survey is offering a funding opportunity for a CESU partner to conduct research on the population dynamics of warmwater fishes in the Mississippi basin and non-native invaders in the Colorado River basin. The project aims to develop population models for these species in response to changing hydrology and water temperature, and use these models to forecast their invasion into new river segments. The funding opportunity is a Cooperative Agreement with an award ceiling of $450,000 and an award floor of $200,000. The application deadline is March 27, 2024, at 5:00 p.m. ET.
