Consumer‐resource stoichiometry in detritus‐based streams
Stoichiometric relationships between consumers and resources in detritus-based ecosystems have received little attention, despite the importance of detritus in most food webs. We analysed carbon (C),Expand
The contribution of headwater streams to biodiversity in river networks
The diversity of life in headwater streams (intermittent, first and second order) contributes to the biodiversity of a river system and its riparian network. Small streams differ widely in physical,Expand
The role of macroinvertebrates in stream ecosystem function.
This review focuses on some of the roles of macroinvertebrate functional groups, i.e. grazers, shredders, gatherers, filterers, and predators, in stream-ecosystem processes. Many stream-dwellingExpand
Life history and production of stream insects.
Studies of the production of stream insects are now numerous, and general factors controlling the secondary production of stream communities are becoming evident. In this review we focus on howExpand
Nutrients stimulate leaf breakdown rates and detritivore biomass: bottom-up effects via heterotrophic pathways
Most nutrient enrichment studies in aquatic systems have focused on autotrophic food webs in systems where primary producers dominate the resource base. We tested the heterotrophic response toExpand
Stream macroinvertebrate response to catchment urbanisation ( Georgia ,
1. The effects of catchment urbanisation on water quality were examined for 30 streams (stratified into 15, 50 and 100 km ± 25% catchments) in the Etowah River basin, Georgia, U.S.A. We examinedExpand
Whole-system nutrient enrichment increases secondary production in a detritus-based ecosystem.
Although the effects of nutrient enrichment on consumer-resource dynamics are relatively well studied in ecosystems based on living plants, little is known about the manner in which enrichmentExpand
Nutrient enrichment reduces constraints on material flows in a detritus-based food web.
Most aquatic and terrestrial ecosystems are experiencing increased nutrient availability, which is affecting their structure and function. By altering community composition and productivity ofExpand
Leaf Litter as a Source of Dissolved Organic Carbon in Streams
ABSTRACT Dissolved organic carbon (DOC) is an abundant form of organic matter in stream ecosystems. Most research has focused on the watershed as the source of DOC in streams, but DOC also comes fromExpand
Organic matter flow in stream food Webs with reduced detrital resource base
Food webs based on flows of organic matter were developed for two small streams to examine food web response to a large reduction in detrital inputs. At the study site, Coweeta Hydrologic LaboratoryExpand
