Development and Validation of Models to Assess the Threat to Freshwater Fishes from Environmental Change and Invasive Species.
June 2009 - September 2011
- Alaska Biological Science Center
Primary Questions/Objectives 1. What are the primary anthropogenic and biotic threats to freshwater ecosystems in the Lower Colorado River Basin, and how do they vary across different spatial scales? 2. Which regional fish faunas are at greatest risk to anthropogenic and biotic threats? 3. What is the association between species distributions and community composition (both taxonomic and functional) and specific threat indices at different spatial scales, and what are the predicted effects of future environmental change?
