Effects of euthanasia method on stable‐carbon and stable‐nitrogen isotope analysis for an ectothermic vertebrate [PDF]
Rapid Communications in Mass Spectrometry, 2013 RATIONALE Stable isotope analysis is a critical tool for understanding ecological food webs; however, results can be sensitive to sample preparation methods. To limit the possibility of sample contamination, freezing is commonly used to euthanize invertebrates and preserve non‐lethal samples from vertebrates ...

Stable isotopes in diatom silica [PDF]
, 2010 Diatom silica is a form of biogenic opal (SiO2.nH2O, Figure 1) containing oxygen, silicon, carbon and nitrogen isotopes that can be used in lacustrine and marine paleoenvironmental studies.

Using stable isotopes to follow excreta N dynamics and N2O emissions in animal production systems
Animal, 2013 Nitrous oxide (N2O) is a potent greenhouse gas and the dominant anthropogenic stratospheric ozone-depleting emission. The tropospheric concentration of N2O continues to increase, with animal production systems constituting the largest anthropogenic ...

Neanderthals, hypercarnivores, and maggots: Insights from stable nitrogen isotopes
Science AdvancesReconstructions of Eurasian Neanderthal diets based on stable nitrogen isotope ratios (δ 15 N) typically place hominins at the top of the food web, together with, or above, hypercarnivores, such as lions and wolves.
