Degradation changes stable carbon isotope depth profiles in palsa peatlands [PDF]
Biogeosciences, 2014 Palsa peatlands are a significant carbon pool in the global carbon cycle and are projected to change by global warming due to accelerated permafrost thaw. Our aim was to use stable carbon isotopes as indicators of palsa degradation.

Food webs in forest and pasture streams in the Waikato region, New Zealand: A study based on analyses of stable isotopes of carbon and nitrogen, and fish gut contents. [PDF]
, 1997 Stable isotopes of carbon (C) and nitrogen (N) were studied in 11 stream communities in the Waikato region of New Zealand. From comparisons of mean d13C and d15N values, food webs in the shaded, forest streams were clearly based on allochthonous material

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.

Stable and radiogenic isotopes as tracers for soil degradation [PDF]
, 2008 Soil erosion seriously threatens mountain slopes. Direct measurement of soil erosion in the field is difficult and needs long term recording. However, stable and radiogenic isotopes are potential tracers for soil erosion estimation and would enable a ...

Structure and flow of carbon and nitrogen to the western Irish Sea Nephrops norvegicus fishery: a stable isotope approach. [PDF]
, 2008 PhDStable isotope analysis was used to describe the structure and flow of organic matter (carbon and nitrogen) from primary production in the water column to the benthos, and into secondary production that supports a fishery for the lobster Nephrops ...

A pilot study of stable isotope fractionation in Bombyx mori rearing
Scientific Reports, 2023 Hydrogen, oxygen, carbon, and nitrogen isotopes derived from three different strains of silkworms at different life stages involved in silkworm rearing, were measured to understand the fractionation characteristics of stable isotopes at different stages ...

Centrifugal Separation of Carbon Isotopes Using Heptafluoropropane as Processing Gas
Journal of Isotopes, 2020 The demand for stable isotopes has increased in the field of medical diagnosis, biopharming, quantum communication and so on. Natural carbon has two stable isotopes: 12C (98.89%) and 13C (1.11%). 13C in high abundance is mainly used in tracer field.
