...Nathan Wolf; Seth D. Newsome; Marilyn L. Fogel; Carlos Martínez del Rio SUMMARY The analysis of hydrogen stable isotopes (∂D) is a potentially powerful tool for studying animal ecology. Unlike other stable isotopes used in ecological research, however, we are less familiar with the physiological...

... rates, carbon and nitrogen stable isotope analysis in manatee epidermis is useful in summarizing average dietary intake over a long period of time rather than assessing recent diet. In addition to turnover rate, a diet–tissue discrimination value of 2.8‰ for 13 C was calculated for long-term captive...

... with dietary sugar. Using indirect calorimetry, i.e. measurement of rates of O 2 consumption and CO 2 production, in combination with carbon stable isotope techniques, we found that nectarivorous bats Glossophaga soricina use recently ingested sugars to provide ∼78%of the fuel required for oxidative metabolism...

... on the amaranth diet had higher 13 C enrichment (2.0±0.2‰) than bats on the soya diet (0.1±0.1‰). Our results support recent hypotheses of the effect of nutrition on diet-tissue isotopic discrimination and turnover rate, and further shows that blood stable isotope analysis is an adequate approach to track...
