Pre-Whaling Genetic Diversity and Population Ecology in Eastern Pacific Gray Whales: Insights from Ancient DNA and Stable Isotopes
Population Ecology Pre-Whaling Genetic Diversity
2015/12/11
Commercial whaling decimated many whale populations, including the eastern Pacific gray whale, but little is known about
how population dynamics or ecology differed prior to these removals. Of partic...
δ18O water isotope in the iLOVECLIM model (version 1.0) – Part 3: A palaeo-perspective based on present-day data–model comparison for oxygen stable isotopes in carbonates
δ18O water isotope LOVECLIM model A paleo-perspective present-day data–model comparison oxygen stable isotopes carbonates
2014/12/12
Oxygen stable isotopes (δ18O) are among the most useful tools in palaeoclimatology/palaeoceanography. Simulation of oxygen stable isotopes allows testing how the past variability of these isotopes in ...
Revealing organic carbon sources fueling a coral reef food web in the Gulf of Mexico using stable isotopes and fatty acids
Revealing organic carbon sources coral reef food web Gulf of Mexico stable isotopes fatty acids
2014/4/2
Carbon and nitrogen stable isotopes and fatty acids (FAs) revealed primary producer organic carbon sources that fuel a coral reef food web with river influence. A stable isotope mixing model was used ...
Statistical Analysis of Rice Samples for Compositions of Multiple Light Elements (H, C, N, and O) and Their Stable Isotopes
Rice Samples Compositions of Multiple Light Elements
2010/9/15
Stable isotopic compositions and elemental contents of the H, C, N, and O in 163 rice samples were analyzed. The samples were taken from three different farming countries; Japan (n = 103), United Stat...
Interpretation of benthic foraminiferal stable isotopes in subtidal estuarine environments
Interpretation benthic foraminiferal stable isotopes subtidal estuarine environments
2010/1/21
Here we present a novel approach for the interpretation of stable isotope signatures recorded in benthic foraminifera from subtidal estuarine environments. The stable isotopic composition (δ18O and δ1...
Estimating Evaporation Using Stable Isotopes:Quantitative Results and Sensitivity Analysis for Two Catchments in Northern Canada
Stable Isotopes Quantitative Results Sensitivity Analysis
2009/10/26
The stable isotope-mass balance method can provide useful water balance
information in ungauged catchments. The method has been used to evaluate
evaporation and water balance at two contrasting site...
Preliminary Identification of Ground-water Nitrate Sources Using Nitrogen and Carbon Stable Isotopes,Kansas
Preliminary Identification Ground-water Nitrate Sources Nitrogen and Carbon Stable Isotopes
2009/10/20
Increasing nitrate-N in ground water is a problem in many areas with limited ground-water supplies, such as west-central Kansas. However, potential sources of nitrate-N are not known. Nitrate-N concen...
Studies and applications of stable isotopes in precipitation
climate variability GCMs paleoclimate stable isotopes in precipitation
2009/7/14
This paper reviews observation- and model-based studies of stable isotopes in precipitation and discusses the Global Network for Isotopes in Precipitation (GNIP) and other regional networks and projec...
Spatial and temporal variability of prairie lake hydrology as revealed using stable isotopes of hydrogen and oxygen
Spatial temporal variability hydrogen and oxygen
2014/4/17
Evaporation and groundwater fluxes are thought to regulate hydrologic variability in lakes of the northern
Great Plains, but little is known of how the relative importance of these processes may vary...
