Project Title: 
Consequences of disturbance history on community assembly in Andean headwater streams
Project Abstract: 
Human exploitation of freshwater systems has altered stream flows worldwide. Natural stream flow variability that native biota have adapted to over evolutionary time has been disrupted due to impoundments, water withdrawals for irrigation and global climate change. The goal of the proposed research is to better understand the influences of local large-scale landscape disturbances, stream flow dynamics and dispersal limitation in structuring headwater stream communities the Ecuadorian Andes. The Ecuadorian Andes contain strong environmental gradients across headwater streams, which are information-poor systems that are currently under direct threat from hydroelectric development.
