Temporal variation in the baseline stable carbon isotope (δ13C) value of a well-studied, productive lake was examined over a 26-yr period using archived samples of the herbivorous zooplankter Daphnia ...

A pattern of succession has been demonstrated at Gulf of Mexico cold seeps proceeding from a high-biomass endemic community dominated by grazers to a diverse community of endemic and nonendemic speci...
We tested the hypotheses that benthic macroinvertebrates, especially chironomid larvae in the Tribe Chironomini, from small oligotrophic arctic lakes are only weakly linked to pelagic food sources, a...
Water movement affects carbon and nitrogen isotopic signatures of algae, possibly through effects on boundarylayer thickness. We describe a laboratory experiment carried out in artificial streams, whi...
Zooplankton are commonly used to establish a baseline isotopic signature for pelagic production in lakes. Our objective was to evaluate this approach by quantifying among-lake and within-lake variabil...
In a subset of a stream food web, whole-body isotope values of d13C and d15N were measured for eight populations of lotic invertebrates. Observed isotopic differences among species corresponded broadl...
