We review the major conceptual developments that have occurred over the last 50 years concerning the factors that influence insect biodiversity in streams and examine how well empirical descriptions and theory match. Stream insects appear to respond to both spatial and temporal variation in physical heterogeneity. At all spatial scales, the data largely(More)
We compared sources of variability and cost in paired stomach content and stable isotope samples from three salmonid species collected in September 2001–2005 and describe the relative information provided by each method in terms of measuring diet overlap and food web study design. Based on diet analyses, diet overlap among brown trout, rainbow trout, and(More)
New Zealand mud snails (Potamopyrgus antipodarum, NZMS) are invading North American freshwaters and altering native invertebrate assemblages, suggesting adverse effects may be felt by native fish populations. I examined trophic effects of NZMS in the Green River downstream from Flaming Gorge Dam (Utah), based on fish stomach contents, stable isotope(More)
We analyzed angling catch records for 341,959 muskellunge (Esox masquinongy) from North America to test for a cyclic lunar influence on the catch. Using periodic regression, we showed that the number caught was strongly related to the 29-day lunar cycle, and the effect was consistent across most fisheries. More muskellunge were caught around the full and(More)
