Stable isotope analyses reveal major nutritional deficiencies in captive vs. field juvenile individuals of Pinna nobilis

Combining stable isotope analyses and geolocation to reveal kittiwake migration

Determining migratory strategies of seabirds is still a major challenge due to their relative inaccessibility. Small geolocators are improving this knowledge, but not all birds can be tracked. Stable isotope ratios in feathers can help us to understand migration, but we still have insufficient baseline knowledge for linking feather signatures to movements amongst distinct water masses. To under...

YEARBOOK OF PHYSICAL ANTHROPOLOGY 34:283-321 (1991) Stable Isotope Analyses in Human Nutritional Ecology

Extracting nutrients is of upmost importance to the survival of any individual or species. One of the distinguishing characteristics of the order Primates is the vast range of nutritional adaptations it exhibits. Within our own species all manner of adaptations are practiced and it has been a major focus of research to determine when and where these various patterns originated. We present one m...

Stable Isotope Analyses of Tooth Annuli Reveal Temporal Dietary Records: An Example Using Stellar Sea Lions

Stable Isotope Application in Animal Nutrition Science

The application of stable isotope analysis (SIA) has become a standard scientific approach in Agricultural and Ecological researches and, more in general, in several disciplines such as biology, botany, zoology, organic chemistry, climatology, and nutrition. The main objectives of this paper are (1) to provide a simple definition of stable isotopes and (2) to illustrate analytical measurement m...

STABLE-ISOTOPE SIGNATURES (dC AND dN) OF DIFFERENT TISSUES OF PINNA NOBILIS LINNAEUS, 1758 (BIVALVIA): ISOTOPIC VARIATIONS AMONG TISSUES AND BETWEEN SEASONS

The fan mussel Pinna nobilis is a rapidly growing suspension-feeding bivalve endemic to the Mediterranean Sea and usually inhabits seagrass meadows. This endangered bivalve assimilates carbon and nitrogen isotopic ratios in tissues from its food sources. The dC and dN signatures were used to demonstrate isotopic variation among three tissues (digestive gland, gills and muscle) and (for digestiv...
