Chloride concentrations in surface waters have been increasing over the last several decades at multiple locations throughout the United States. At times, it appears that ambient chloride concentrations now reach…
This project tests the hypothesis that temperature limits the distributions of aquatic insects through its effect on resource allocation, and that warming decreases reproduction by shunting energy away from egg…
Funk’s insatiable curiousity has served him well during 45 years as a instrumental player on landmark freshwater studies at the Stroud Center.
When stream temperatures rise, often as a result of climate change or thermal pollution or a lack of tree shade, mayflies display poorer growth.
