Studies of anthropogenic impacts on wildlife may produce inconclusive or biased results if they
fail to account for natural sources of variation in breeding performance and do not use probabilistic sampling

Dams impound the majority of rivers and provide important societal benefits, especially daily water releases that enable on-peak hydroelectricity generation. Such “hydropeaking” is common worldwide, but its downstream impacts remain unclear. We evaluated the response of aquatic insects, a cornerstone of river food webs, to hydropeaking using a life history–hydrodynamic...
