... the experiment, bats were sustained on a normal diet with a low δ 15 N and δ 13 C. Under this first food regime, the fractionation of nitrogen isotopes averaged 3.1‰δ 15 N for blood and 4.4‰ δ 15 N for wing membrane, which was almost twice as high as the corresponding fractionation of carbon isotopes. After...

... fractionation Stable isotopes of carbon occur at varying ratios as a consequence of the specific enzymatic route of CO 2 -fixation (C 3 or C 4 /CAM) in plants and in animals according to their diet (DeNiro and Epstein, 1978 , 1981 ). These observations are the basis for studies on dietary preferences...
