Experimental d13 C evidence for a contribution of methane to pelagic food webs in lakes
methane to pelagic food webs Experimental
2014/5/5
We tested the hypothesis that low stable carbon isotope (d13
C) values commonly observed for zooplankton in
humic lakes are due to their feeding on isotopically light methane-oxidizing microbes, and...
Major contribution from littoral crustaceans to zooplankton species richness in lakes
littoral crustaceans zooplankton species
2014/5/5
A study of pelagic and littoral species richness among microcrustaceans in 2,466 Norwegian lakes recorded 120
crustacean species: 77 cladocerans, 31 cyclopoids, and 12 calanoids, respectively. Very f...
Nutrient and light availability regulate the relative contribution of autotrophs and heterotrophs to respiration in freshwater pelagic ecosystems
Nutrient light availability regulate the relative contribution
2014/4/23
In this study, two main hypotheses were addressed. (1) Bacteria contribute proportionally less than autotrophs to
ecosystem respiration as trophic status increases. This hypothesis was examined in a ...
Contribution of phytoplankton and bacterial cells to the measured alkalinity of seawater
phytoplankton bacterial cells
2014/4/23
We report the first direct measurements of the contribution of phytoplankton and bacterial cells to the measured
alkalinity of unfiltered seawater. Phytoplankton and bacterial cells suspe...
