... used to prepare media (−23.6±0.5‰). The differences between the δ 13 C values of the pure sugars and the ovaries were primarily caused by the presence of additional carbon sources in the diet, especially corn meal and yeast ( Table 1 ). As expected, stable isotope ratios in the ovaries remained...

...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...

... using delta notation. These values were calibrated using a standard mixture consisting of ethyl and methyl esters of 14:0, 16:0, 18:0 and 20:0 supplied by Indiana University Stable Isotope Reference Materials, where r 2 of the known versus expected relationship was >0.98. A three-level...

... 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...
