Cetacean occurrence, habitat preferences and potential for cetacean-fishery int...
Goetz, Sabine; Read, Fiona L.; Ferreira, Marisa; Martínez Portela, Julio; Begoña Santos, Maria; Vingada, José; Siebert, Ursula; Marçalo, AnaIberian Atlantic waters are heavily exploited by Spanish and Portuguese fisheries. Overlaps between fishery target species and cetacean diet, and between fishing grounds and cetacean foraging areas, can lead to cetacean–fishery interactions including bycatch mortality of cetaceans. The present study assesses cetacean distribution, habitat preferences and hotspots for cetacean–fishery interactions by using a coo...

An assessment of contaminant concentrations in toothed whale species of the NW ...
Méndez-Fernandez, Paula; Webster, Lynda; Chouvelon, Tiphaine; Bustamante, Paco; Ferreira, Marisa; González, Angel F.; López, Alfredo; Moffat, Colin F.Concentrations and patterns of polychlorinated biphenyls (PCBs) and polybrominated diphenyl ethers (PBDEs) in the blubber of the five most common toothed whales off the Northwest Iberian Peninsula (NWIP), specifically common dolphin, long-finned pilot whale, harbour porpoise, striped dolphin and bottlenose dolphin, were investigated. The study revealed that differences in PCB and PBDE concentrations among the s...

Méndez-Fernandez, Paula; Pierce, Graham J.; Bustamante, Paco; Chouvelon, Tiphaine; Ferreira, Marisa; González, Angel F.; López, Alfredo; Read, Fiona L.This study aims to assess niche segregation among the five main toothed whales that frequent the NW Iberian Peninsula waters: the common dolphin, the harbour porpoise, the bottlenose dolphin, the striped dolphin and the long-finned pilot whale. We used cadmium (Cd) and stable isotope ratios (delta C-13 and delta N-15) as ecological tracers to assess degree of segregation in diet/trophic level and in foraging ha...
