Abstract

In Brazil, freshwater ecosystems are facing multiple anthropogenic pressures, such as agricultural intensification, urbanization and intensifying climate change effects. To disentangle these effects, multiple-stressor research seeks to analyze the variety of stressors acting simultaneously to elucidate how stressor interactions affect individual organisms to whole ecosystems. The aim of this project is to conduct the first mesocosm experiments investigating the interactive effects of climate change and agricultural stressors on freshwater organisms in Brazil. The experiments will disentangle the individual and combined effects of agricultural intensification and climate change on benthic stream macroinvertebrates as a model community. Understanding how climate and agricultural stressors individually and interactively impact aquatic organisms will inform stressor mitigation prioritization and best-practice agricultural management to protect freshwater ecosystems.
