NovakLab Publications Trematode parasites exceed aquatic insect biomass in Oregon stream food webs Although parasites are increasingly recognized for their ecosystem roles, it is often assumed that free-living organisms dominate … Preston, Layden, Segui, Falke, Brant, Novak Preprint PDF Cite DOI Data SOM Temporal shifts in intraspecific and interspecific diet variation among 3 stream predators Intraspecific variation is increasingly recognized as an important factor in ecological interactions that can exceed the role of … Falke, Henderson, Novak, Preston Preprint PDF Cite DOI Data SOM 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 … Preston, Falke, Henderson, Novak Preprint PDF Cite DOI Data SOM 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 … Segui PDF Cite What drives interaction strengths in complex food webs? A test with feeding rates of a generalist stream predator Describing the mechanisms that drive variation in species interaction strengths is central to understanding, predicting, and managing … Preston, Henderson, Falke, Segui, Layden, Novak Preprint PDF Cite DOI Data Contributions of parasites to energy flow through a stream food web Parasites are increasingly recognized for their significant roles in shaping community structure and ecosystem dynamics. Due to their … Layden Poster Using Survival Models to Estimate Invertebrate Prey Identification Times in a Generalist Stream Fish Estimates of predator feeding rates are important for understanding trophic dynamics. One common method for quantifying feeding rates … Preston, Henderson, Falke, Novak PDF Cite DOI Data SOM 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 … Saepharn Using the functional response of a consumer to predict biotic resistance to invasive prey Predators sometimes provide biotic resistance against invasions by nonnative prey. Understanding and predicting the strength of biotic … Twardochleb, Novak, Moore PDF Cite DOI Nestedness patterns and the dual nature of community reassembly in California streams: a multivariate permutation-based approach Many factors contribute to the nonrandom processes of extinctions and invasions that are changing the structure of ecological … Novak, Moore, Leidy PDF Cite Code DOI Data SOM
