Temporal shifts in intraspecific and interspecific diet variation among 3 stream predators
Food-web interaction strength distributions are conserved by greater variation between than within predator--prey pairs
Species interactions in food webs are usually recognized as dynamic, varying across species, space, and time because of biotic and …

Food-web interaction strength distributions are conserved by greater variation between than within predator--prey pairs
State-structured species interactions and their consequences across levels of biological organization

A central challenge for ecology is to understand the dynamic nature of species interactions. A classic approach to community ecology …

Competitive mechanisms underlying the displacement of native crayfish by non-native crayfish

Invasive species are one of the greatest threats to biodiversity around the world. Although a seemingly harmless act, species …
Using the functional response of a consumer to predict biotic resistance to invasive prey
