The objectives of the project are:

  1. Compare the trophic niche that is occupied by California kingsnake populations in Gran Canaria 

  2. Investigate if there are changes in the trophic niche associated with sex and the ontogeny of species

  3. Determine turnover rate and discrimination factor for the species, parameters needed for stable isotope analyses

  4. Study diet composition using stable isotopes and compare it with results from gastrointestinal content analysis
