Abstract Pteronarcys stoneflies, which are traditionally considered shredders in eastern North America, inhabit second- through seventh-order streams in the Little Tennessee River (LTR) drainage basin. Because very little coarse allochthonous particulate organic matter occurs in the relatively large (sixth- and seventh-order) LTR, we analyzed the gut contents of five individuals from each of five sites and two dates (August and December) (n = 50) along a fourth- through seventh-order stretch of… 

Trophic Levels and Functional Feeding Groups of Macroinvertebrates in Neotropical Streams

It is observed that practically all macroinvertebrates fed upon fine detritus which indicates the importance of this food resource in neotropical streams and the affinity of taxa to each FFG using fuzzy codes is transcribed.

Ecological speciation by temporal isolation in a population of the stonefly Leuctra hippopus (Plecoptera, Leuctridae)

An atypical population of the stonefly Leuctra hippopus at a site in central Norway, the Isterfoss rapids, is studied and it is concluded that this population is in the process of sympatric speciation, with temporal isolation being the most important direct barrier to gene flow.

Habitat Segregation and Nymphal Life History of Two Nesameletus Species (Ephemeroptera: Nesameletidae) in a Mountain Stream

It is proposed that the selection of oviposition sites by females is the primary mechanism determining the distribution of nymphs within and outside forest.

Retesting a prediction of the River Continuum Concept: autochthonous versus allochthonous resources in the diets of invertebrates

In invertebrate diets from the Salmon River, Idaho, are investigated by examining the gut contents of archived specimens from the longitudinal set of sites sampled in the original 1976 RCC study and by collecting invertebrates from these same sites in 2009, finding no apparent shifts in diets over the ∼30-y time span.

Invertebrate food webs along a stream resource gradient

SUMMARY 1. The flow of energy through food webs with similar species can vary with both space and time. The river continuum concept (RCC) provides a useful framework for predicting variability in the

Food webs in tropical Australian streams: shredders are not scarce

Comparison of the fauna of 20 streams showed that the study sites were similar to, or not atypical of, low-order streams in the Queensland wet tropics.

Numerical and per capita responses to species loss: mechanisms maintaining ecosystem function in a community of stream insect detritivores

There was no simple relationship between biodiversity and ecosystem functioning, however, when numerical or per capita compensation does occur, stability of function should rise with diversity in such “interactive” assemblages.

Elevated Allochthony in Stream Food Webs as a Result of Longitudinal Cumulative Effects of Forest Management

The river continuum concept (RCC) predicts a downstream shift in the reliance of aquatic consumers from terrestrial to aquatic carbon sources, but this concept has rarely been assessed with

Movement patterns and ecology of Pteronarcys nymphs (Plecoptera).: Observations of marked individuals in a Rocky Mountain stream

The Pteronarcys californica (Newport) nymphs were caught and recaptured over a 3-month period to determine their movement patterns and home range size, and females were larger than males at all ages.

Macroinvertebrate functional feeding groups in the middle and lower reaches of the Buffalo River, eastern Cape, South Africa. I. Dietary variability

SUMMARY 1  The question of whether the diets of twelve abundant macroinvertebrate taxa from the middle and lower reaches of the Buffalo River (eastern Cape, South Africa) were too variable to

The Transformation of Energy by a Stream Detritivore, Pteronarcys Scotti (Plecoptera)

The bioenergetics of a detritus—feeding stonefly Pteronarcys scotti, were invetigated and a 17—month energy budget for the average nymph was tabulated.

Trophic Basis of Production Among Net-Spinning Caddisflies in a Southern Appalachian Stream

The results show that the omnivorous caddisflies are not the major consumer of detritus and algae, and that they produce moredetritus in their feces than they consume, thusearing to lower the food quality of the seston.

Stable carbon and nitrogen isotope analysis of seston in a regulated Rocky Mountain river, USA

The isotopic composition of stonefly larvae, Pteronarcys californica, varied among sites, and closely matched that of the local seston (especially FPOM), suggesting that with respect to detritus origin, larvae were opportunistic foragers.

Variation in genetic structure among populations of the caddisfly Helicopsyche borealis from three streams in northern California, U.S.A.

Geographical and taxonomic differences observed in this study underscore the importance of understanding both population structure and genetic relationships among populations in the design and interpretation of stream faunal studies.

Population genetics of the burrowing mayfly Dolania americana : geographic variation and the presence of a cryptic species

The genetic structure of Dolania populations in South Carolina, Alabama, and Florida was examined using starch gel electrophoresis and revealed that the Alabama site contained both D. americana Edmunds and Traver and an undescribed species.

Trophic Relations of Aquatic Insects

The present focus is on the level at which generaliza­ tions are possible and the ecological importance of such generalizations, rather than the food habits of particular species.

Genetic Variation in Stream Mayfly (Insecta: Ephemeroptera) Populations of Eastern North America

The biochemical data suggest that the currently accepted classification of these genera should be reassessed, andeterogeneity of inbreeding values among loci in a given species suggests possible selection at some loci.
