Inter- and intraspecies differences in biomarker responses and contaminant levels in two mysticete species (Balaenoptera physalus and Balaenoptera edeni) of Gulf of California (Mexico) and Mediterranean Sea
Inter- and intra-species differences in biomarker responses and contaminant levels were investigated in twomysticete species, finwhale (Balaenoptera physalus) and the unexplored species Bryde whale (Balaenoptera edeni) of Gulf of California (Mexico) and fin whale of Mediterranean Sea, using skin bio...
