Stable Isotope Q Fig.1 Stable Isotope Signiture for Species 1,2, and 3. 1. Based on Figure 1, which species feeds highest on the food chain? Which species is the dominant prey species for species 1 ? Figure 2. Contribution (fraction) of isotope signature indicative of vole consumption in plasma, red blood cells (RBC) or scale from the snake C. c. foxii. 2. Did this snake exhibit a diet shift in terms of the number of voles it has consumed? Has it eaten more, less, or the same number of voles recently than it had previously eaten? 3. List two advantages and two disadvantages each of gut content analysis and stable isotope analysis in accurately determining an organism's diet..

which species feeds highest on the food chain? Which species is the dominant prey species for
species 1 ? Figure 2. Contribution (fraction) of isotope signature indicative of vole consumption in
plasma, red blood cells (RBC) or scale from the snake C. c. foxii. 2. Did this snake exhibit a diet
shift in terms of the number of voles it has consumed? Has it eaten more, less, or the same
number of voles recently than it had previously eaten? 3. List two advantages and two
disadvantages each of gut content analysis and stable isotope analysis in accurately determining
an organism's diet.
