Tooth microwear texture in odontocete whales: variation with tooth characteristics and implications for dietary analysis
Understanding the diets and trophic relationships of toothed whales is central to understanding their roles in marine ecosystems, and associated conservation issues. Yet this is problematic because direct observation of what free ranging marine mammals eat is difficult. Quantitative 3D textural anal...
