Stable isotope analysis provides new information on winter habitat use of declining avian migrants that is relevant to their conservation [PDF]
, 2012 Winter habitat use and the magnitude of migratory connectivity are important parameters when assessing drivers of the marked declines in avian migrants. Such information is unavailable for most species.

Global Ecology and Conservation, 2023 Stable isotopes of animal tissue have been used to estimate diet for many consumer species and places, but the ability to assign contributions to all food items is limited by the number of tracers used, and the separation of the tracer data among the ...

Degradation changes stable carbon isotope depth profiles in palsa peatlands [PDF]
, 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.

Importance of vegetation, topography and flow paths for water transit times of base flow in alpine headwater catchments [PDF]
, 2013 The mean transit time (MTT) of water in a catchment gives information about storage, flow paths, sources of water and thus also about retention and release of solutes in a catchment.

Stable Isotopes for Tracing Cardiac Metabolism in Diseases
Frontiers in Cardiovascular Medicine, 2021 Although metabolic remodeling during cardiovascular diseases has been well-recognized for decades, the recent development of analytical platforms and mathematical tools has driven the emergence of assessing cardiac metabolism using tracers. Metabolism is

Radial and axial water movement in adult trees recorded by stable isotope tracing.
Tree Physiology, 2021 The capacity of trees to release water from storage compartments into the transpiration stream can mitigate damage to hydraulic functioning. However, the location of these 'transient' water sources, and also the pathways of water movement other than ...

Probing stratospheric transport and chemistry with new balloon and aircraft observations of the meridional and vertical N2O isotope distribution [PDF]
, 2006 A comprehensive set of stratospheric balloon and aircraft samples was analyzed for the position-dependent isotopic composition of nitrous oxide (N2O). Results for a total of 220 samples from between 1987 and 2003 are presented, nearly tripling the number

13C Tracer Studies of Metabolism in Mouse Tumor Xenografts
Bio-Protocol, 2015 Mice are widely used for human tumor xenograft studies of cancer development and drug efficacy and toxicity. Stable isotope tracing coupled with metabolomic analysis is an emerging approach for assaying metabolic network activity.
