We explored the role of light-saturated (carbon-limited) photosynthesis ond13C of turtlegrass (Thalassia testudinumBanks ex Ko¨ nig) populations from the clear, blue waters of the Great Bahama Bank an...
Decadal diagenetic effects on d13 C and d15N studied in varved lake sediment

To assess the long-term (27 yr) effects of sediment aging on stable carbon and nitrogen isotope values (d13
C
and d15N), we used a collection of eight freeze cores of annually laminated (varved) lak...

To assess variability in carbon isotope signatures (d13
C) between and within populations under natural
conditions, with a particular emphasis on colony size, we repeatedly collected planktonic colo...
Interdecadal variation in seawater d13 C and d18O recorded in fish otoliths

Stable carbon (d13
C) and oxygen (d18O) in the otolith cores of Atlantic bluefin tuna (Thunnus thynnus) vary
temporally, with changes that quantitatively follow interdecadal variation in atmospheric...
Experimental d13 C evidence for a contribution of methane to pelagic food webs in lakes

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...
