Harbor porpoise thyroids: histologic investigations and potential interactions with environmental factors.
The thyroid plays an important role in development and is of primary importance in metabolism and heat loss for cetaceans, including the harbor porpoise (Phocoena phocoena). Several studies have demonstrated that environmental contaminants can alter various aspects of thyroid function in mammals and may contribute to various histologic changes. The present study completes the data set of a 2006...
متن کاملHarbor Porpoise and Fisheries: an Uncertainty Analysis of Incidental Mortality
The harbor porpoise (Phocoena phocoena) in the western North Atlantic is subject to mortality due to entanglement in gillnets. Such incidental mortality threatens a population if it is too large relative to the potential population growth rate. Critical values for incidental mortality have been established by the International Whaling Commission and the U.S. Marine Mammal Protection Act. As in ...

متن کاملRespiratory properties of blood in the harbor porpoise, Phocoena phocoena.
Harbor porpoises are active divers that exchange O(2) and CO(2) with the environment during a fast single breath upon surfacing. We investigated blood O(2)-transporting properties, buffer characteristics, Cl(-) transport via the erythrocyte anion exchanger (AE1), circulating nitric oxide metabolites and hemoglobin nitrite reduction in harbor porpoises with the aim to evaluate traits that are ad...
متن کاملHARBOR PORPOISE (Phocoena phocoena): Northern California/Southern Oregon Stock
STOCK DEFINITION AND GEOGRAPHIC RANGE In the Pacific, harbor porpoise are found in coastal and inland waters from Point Conception, California to Alaska and across to Kamchatka and Japan (Gaskin 1984). Harbor porpoise appear to have more restricted movements along the western coast of the continental U.S. than along the eastern coast. Regional differences in pollutant residues in harbor porpois...
