...Erling S. Nordøy; Anne R. Lager; Pauke C. Schots ABSTRACT The aim of this study was to monitor seasonal changes in stable isotopes of pool freshwater and harp seal ( Phoca groenlandica ) body water, and to study whether these potential seasonal changes might bias results obtained using the doubly...

... in amphibians. Most studies have relied upon destructive sampling to track changes in lipid composition; however, advances in stable isotope breath analysis allows for repeated measures on lipid and protein oxidation across ontogeny. Labelling macronutrient pools with 13 C allows measurements of rates...
