TLDR
Hydrogen isotopic analyses of beetle chitin demonstrate the potential for development of a palaeoclimatic tool that can be used to complement current palaeoentomological methods, and demonstrate small interspecific and intraspecific variation in beetles of different habit.About:

Influence of Diet On the Distribtion of Nitrogen Isotopes in Animals
Michael J. DeNiro,Samuel Epstein +1 more
TL;DR: In this article, the influence of diet on the distribution of nitrogen isotopes in animals was investigated by analyzing animals grown in the laboratory on diets of constant nitrogen isotopic composition and found that the variability of the relationship between the δ^(15)N values of animals and their diets is greater for different individuals raised on the same diet than for the same species raised on different diets.

Influence of drinking water and diet on the stable-hydrogen isotope ratios of animal tissues
TL;DR: Environmental interpretations of deltaD values from modern and fossil animal tissues may need to account for potentially large isotopic differences between drinking water and food and require a good understanding of the physiological ecology of study organisms.

Improved Method for Determining the Stable-Hydrogen Isotopic Composition (δD) of Complex Organic Materials of Environmental Interest
TL;DR: Despite new and increasing applications in environmental studies, determinations of the stable-hydrogen isotope (δD) composition of complex organic substrates are hampered by laborious preparation as discussed by the authors.

Estimating the latitudinal origins of migratory birds using hydrogen and sulfur stable isotopes in feathers: influence of marine prey base
TL;DR: It is suggested to use a practical cutoff of δ34S >10‰ to remove marine-foraging birds from a migrant sample when using stable isotopes of hydrogen to estimate the latitudinal origins of migrants because high δDf values for marine- foraging birds could potentially distort estimates of origins.

TL;DR: In this article, the influence of diet on the distribution of nitrogen isotopes in animals was investigated by analyzing animals grown in the laboratory on diets of constant nitrogen isotopic composition and found that the variability of the relationship between the δ(15)N values of animals and their diets is greater for different individuals raised on the same diet than for the same species raised on different diets.
