Life history traits of the fish community in Lake Annecy: evidence from the stable isotope composition of otoliths

Knowledge and Management of Aquatic Ecosystems, 2015
Stable isotope analysis (SIA) of fish otoliths shows great potential for exploring the ecology of fish, but this method has not been applied to the study of lacustrine fish communities.

Identification of secondary microbial methane and biodegradation: Case study from Luliang oil and gas field, Junggar Basin, China

Journal of Natural Gas Geoscience, 2019
The “secondary microbial gas” is defined as natural gas generated via the biodegradation of oil reservoirs. Since methane dominates, it is also called “secondary microbial methane”.

The effect of 12C + 12C rate uncertainties on s-process yields [PDF]

, 2010
The slow neutron capture process in massive stars (the weak s-process) produces most of the s-only isotopes in the mass region 60 < A < 90. The nuclear reaction rates used in simulations of this process have a profound effect on the final s-process ...

Integrating isotopes and documentary evidence : dietary patterns in a late medieval and early modern mining community, Sweden [PDF]

, 2017
We would like to thank the Archaeological Research Laboratory, Stockholm University, Sweden and the Tandem Laboratory (Ångström Laboratory), Uppsala University, Sweden, for undertaking the analyses of stable nitrogen and carbon isotopes in both human and

Global Nitrogen Deposition Promotes Carbon Sink Formation in Terrestrial Ecosystems

Advanced Science, EarlyView.
Nitrogen deposition alleviates ecosystem N limitation and enhances carbon sinks. Using 829 observations, we show 36% of deposited N is retained globally (39.15 Tg N yr−1), with distinct NHx and NOy contributions. This retention drives a terrestrial C sink of 0.88 Pg C yr−1 (25.48%), highlighting the importance of pool‐specific C:N stoichiometry ...

Variation in the isotopic signatures of juvenile gray snapper (Lutjanus griseus) from five southern Florida region [PDF]

, 2010
Measurements of 18O/16O and 13C/12C ratios in the carbonate of juvenile gray snapper (Lutjanus griseus) sagittal otoliths collected during 2001–2005 from different southern Florida regions indicated significant variations in the ratios between Florida ...

Long-term carbon and nitrogen dynamics at SPRUCE revealed through stable isotopes in peat profiles [PDF]

, 2017
Peatlands encode information about past vegetation dynamics, climate, and microbial processes. Here, we used δ15N and δ13C patterns from 16 peat profiles to deduce how the biogeochemistry of the Marcell S1 forested bog in northern Minnesota responded to ...
