Nutrients cause consolidation of soil carbon flux to small proportion of bacterial community

Nature Communications, 2021
The fate of soil carbon depends on microbial processes, but whether different microbial taxa have individualistic effects on carbon fluxes is unknown.

Effects of Upwelling Intensity on Nitrogen and Carbon Fluxes through the Planktonic Food Web off A Coruña (Galicia, NW Spain) assessed with Stable Isotopes

Diversity, 2020
The input of new nutrients by upwelling in shelf waters, and the associated carbon and nitrogen fluxes, can be traced by their stable isotope signatures in organic matter.

Radiocarbon reservoir effects in human bone collagen from northern Iceland [PDF]

, 2012
Human bone collagen from a series of Icelandic human pagan graves was radiocarbon (14C) dated to aid understanding of early settlement (landnám) chronologies in northern Iceland. These individuals potentially consumed marine protein.

Seasonally resolved growth of freshwater bivalves determined by oxygen and carbon isotope shell chemistry [PDF]

, 2010
By means of a monitoring experiment in two rivers in the Netherlands, we establish a relationship between seasonally resolved growth rates in unionid freshwater bivalves and their environment.

A forensic approach to understanding habitat use from stable isotope analysis of (avian) claw material [PDF]

, 2003
1. The potential of using stable isotope signatures of avian claws in order to infer diet and habitat use was investigated. 2. Highly significant relationships observed between stable carbon and nitrogen isotope ratios (¹³C, &

Dry season limnological conditions and basin geology exhibit complex relationships with δ13C and δ15N of carbon sources in four Neotropical floodplains. [PDF]

PLoS ONE, 2017
Studies in freshwater ecosystems are seeking to improve understanding of carbon flow in food webs and stable isotopes have been influential in this work.

Recent freshening in the Kara sea (Siberia) recorded by stable isotopes in Arctic bivalve shells, [PDF]

, 2005
Oxygen and stable carbon isotope records along the growth direction on shells of the bivalve species Astarte borealis and Serripes groenlandicus reliably record all important aspects of the bottom water hydrography in the shallow southeastern Kara Sea ...

Applications of stable carbon isotopes in soil science with special attention to natural 13C abundance approach

Hungarian Geographical Bulletin, 2019
Since the invention of the isotope ratio mass spectrometer, isotope analysis has shed light on many key processes in the Earth’s ecosystems. Stable isotope analysis was first applied in the field of chemistry and geochemistry, while the use of isotopic ...

Stable carbon isotopes in archaeobotanical remains and palaeoclimate

Contributions to Science, 2008
Es descriu una metodologia recent per a inferir la precipitació en el passat basada en l’anàlisi de la composició isotòpica del carboni (δ13C) en restes arqueobotàniques. Un cop descrita la base fisiològica de la tècnica, s’il·lustra l’aplicabilitat de δ13C mitjançant un exemple referent al NE peninsular.
