Temporal shift in nutrient input to cold-seep food webs revealed by stable-isotope signatures of associated communities
cold-seep food webs Temporal shift
2014/4/17
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...
Stable isotope signatures of benthic invertebrates in arctic lakes indicate limited coupling to pelagic production
Stable isotope signatures benthic invertebrates
2014/4/23
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...
Compositional and inter-lake variability of zooplankton affect baseline stable isotope signatures
Compositional and inter-lake variability zooplankton baseline stable isotope signatures
2014/5/21
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...
Stable isotope signatures of lotic invertebrates: Sources of variation, experimental design, and statistical interpretation
Stable isotope signatures lotic invertebrates Sources of variation, experimental design statistical interpretation
2014/6/9
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...
