Inter-species differences in trophic position and diet of three sympatric sea urchin species

Updated: 2015-10-15

Measurements of natural abundances of stable isotopes and direct observation of gut contents were used to determine the trophic positions of three sympatric sea urchin species. The study was conducted across a large geographical extent and between two times of the year to test for spatial and temporal variability in trophic position and diet.
