Food web dynamics / ecosystem role is complicated, needs to be studied case-by-case #ShiffmanDefense

Also used stable isotopes to assess individual diet specialization in 4 species of sharks #TweetingMyOwnPhDDefense #ShiffmanDefense

Relative diet breadth, overlap, trophic position of these sharks varied widely in different sites #TweetingMyOwnPhDDefense #ShiffmanDefense

Analyzed 11 diet breadth & overlap of 11 shark species (here are pictures of me with 7 of them) #ShiffmanDefense

A predator's ecosystem role can vary based on prey availability, competition from other predators #TweetingMyOwnPhDDefense #ShiffmanDefense
