Use of fatty acid signatures to assess food web dysfunction

Through a combination of field and laboratory studies, this project   will evaluate how fatty acid signatures can provide time-integrated   and energy-based depictions of food web structure. We will develop a   fatty acid signature library of available prey for two target   species, lake trout and yellow perch, both of which exhibit poor   reproductive success in Lake Michigan. We propose to assess how   changes in nutritional fatty acids, linked to food web changes, can   affect reproductive success of both species.    (fatty acids); (fatty acid); (fatty acid signatures); (trout); (lake   trout); (yellow perch); (perch)
