Stable isotopes reflect the ecological stability of two high- elevation mammals from the late Quaternary of Colorado. Quaternary Research 77, 408-417.McLean, B.S., Emslie, S.D., 2012. Stable isotopes reflect the ecological stability of two high- elevation mammals from the late Quaternary of ...
Using stable isotopes to confirm the trophic ecology of Arctic charr morphotypes from Lake Hazen, Nunavut, Canada Stable isotopes of carbon and nitrogen were used to examine differences in the feeding ecology of sympatric morphotypes of Arctic charr Sahelinus alpinus f... KRRA Guiguer,JD Reist,M...
We investigated trophic ecology variation among colonies as well as sex- and age-related differences in the diet of the southern giant petrel Macronectes giganteus, a long-lived seabird that is sexually dimorphic in size. We measured stable isotopes (δ13C, δ15N) in blood samples collected du...
Isotopic exchange between snow and atmospheric water vapor: Estimation of the snowmelt component of groundwater recharge in the southwestern United States [1] The contribution of snowmelt to groundwater recharge at four sites in the southwestern United States was evaluated using stable isotopes of O...

Researchers at the Institute of Modern Physics and collaborators have discovered two new isotopes, osmium-160 and tungsten-156, revealing potential for lead-164 to be a stable, doubly magic nucleus. This breakthrough enhances the understanding of nuclear stability and challenges traditional views on ...

Geochemistry Diurnal cycles of leaf water stable isotopes in two pine species UNIVERSITY OF NEVADARENO Franco Biondi MonnarRobertThe diurnal cycle of stable isotopic values in leaf water has not been studied extensively, and the few reports published in the peer-reviewed literature show large ...
Stable carbon and nitrogen isotopes in lake plankton and seston: variability among 10 fractions, two seasons, and two lakesPyhjrvi, located in the centre of an intensive agricultural area in southwest Finland, is an example of a lake suffering from eutrophication. The lake has been intensively ...
Using Water Stable Isotopes in the Unsaturated Zone to Quantify Recharge in Two Contrasted Infiltration RegimesLong-term continuous measurements of gas concentrations in the vadose zone are required to identify gas transport processes. A magnetic sector mass spectrometer, originally developed for industrial...
