Journal ArticleDOI
Mayfly production in a Colorado mountain stream: an assessment of methods for synchronous and non-synchronous species
Russell B. Rader,James V. Ward +1 more
TL;DR: Data demonstrate that species specific production varies with gross changes in elevation, and can provide quantitative criteria for identifying species with well synchronized development and determine when it is appropriate to directly apply cohort methods while avoiding time intensive body size measurements necessary for size-frequency analyses.
Journal ArticleDOI
Spatial patterns of Ephemeroptera, Plecoptera and Tricoptera diversity in fragmented alpine streams
TL;DR: In this paper, the spatial patterns of Ephemeroptera, Plecoptera and Trichoptera diversity in fragmented alpine streams are investigated in the context of alpine watersheds.
Book ChapterDOI
Dammed Rivers of the World: Symposium Rationale
Jack A. Stanford,James V. Ward +1 more
TL;DR: Cummins as discussed by the authors describes a natural river system as an ecological continuum in which the P/R ratio (i.e., the relationship between community production and respiration) changes from much less than unity in heavily canopied reaches of small headwater tributaries to slightly greater than unity on slow, meandering areas of the river near its mouth.
Journal ArticleDOI
Differential sensitivity of Dugesia dorotocephala and Cheumatopsyche pettiti to water acidification: ecological implication for predator-prey interactions.
J. A. Camargo,James V. Ward +1 more
TL;DR: It is concluded that predation pressure can decrease in aquatic macrobenthic communities if prey are more tolerant to water acidification than predators.
Journal ArticleDOI
Diversity, distribution and seasonality of the Simuliidae fauna in a glacial stream system in the Swiss Alps
TL;DR: It is suggested that spatio-temporal habitat heterogeneity ameliorated the negative effects of high discharge conditions in summer, and enabled biotic assemblages to sustain populations under the harsh environmental conditions experienced at this time of the year.
