Anthropogenic stressors often co‐occur in ecosystems, but their combined impacts are rarely assessed using field experiments. Press disturbances particularly can reshape community dynamics, altering their capacity to withstand or recover from acute pulse disturbances by modifying response diversity.

The export of emergent aquatic insects is a critical energy subsidy for terrestrial food webs. While urbanization is known to alter stream communities, its effects on the size structure of these insect subsidies and the subsequent consequences for riparian predators remain poorly understood.

Potential Impacts of Low Flows on Fish Foodscapes and Production in a Braided River
ABSTRACT Changes in river discharge affect the physical composition and connectivity of habitats which, in turn, may shape the spatial distribution of fish food abundance, accessibility and quality—the ‘foodscape’—of river ecosystems. However, the influence of river flows on fish foodscapes has received very little attention from scientists. We studied

Range-wide Distribution and Genetic Structure of Acroneuria frisoni Stark and Brown, 1991 (Plecoptera; Perlidae): Tools for Reintroduction to Central Illinois [PDF]
Acroneuria frisoni Stark & Brown, 1991(Plecoptera: Perlidae), is a highly threatened stonefly species which in Illinois alone has experienced a 98% loss of its historical range. Some previously degraded drainages within the state have improved in quality
