Frontiers in Marine Science (2021)
The conservation of harbor porpoises (Phocoena phocoena) appears to be failing in Europe. There are particular concerns about this species in the Baltic Proper, Black, and Mediterranean Seas, as well…
Stable oxygen isotopes reveal habitat use by marine mammals in the Río de la Plata estuary and adjoining Atlantic Ocean
Drago, Massimiliano; Valdivia, Meica; Bragg, Daniel; González, Enrique M.; Aguilar, Alex; Cardona, Luis
Estuarine, Coastal and Shelf Science (2020)
Detailed knowledge on habitat use by marine mammals is critical for understanding their ecological role and for adequate management. Here, we assess the habitat use patterns of thirteen species of…
First record of Burmeister’s porpoise (Phocoena spinipinnis) in the Falkland Islands (Malvinas)
Weir, Caroline R.; Rutherford, Susan
Marine Biodiversity Records (2019)
The Burmeister’s porpoise Phocoena spinipinnis is a small, poorly-studied, and Near Threatened cetacean species, with a limited geographic range comprising the Pacific and Atlantic coastal temperate waters of five South…
Porpoises the world over: Diversity in behavior and ecology
Teilmann, Jonas; Sveegaard, Signe
Ethology and Behavioral Ecology of Odontocetes (2019)
Unlike the large number of species of true dolphins, there are only seven porpoise or phocoenid species, inhabiting different habitats and climate zones. They range from ice-covered water in the…
Pingers reduce the activity of Burmeister’s porpoise around small-scale gillnet vessels
Clay, T. A.; Alfaro-Shigueto, J.; Godley, B. J.; Tregenza, N.; Mangel, J. C.
Marine Ecology Progress Series (2019)
Incidental mortality (bycatch) in gillnet fisheries is a major threat to many cetacean populations. Acoustic alarms or pingers are a widely adopted management tool used to deter dolphins and porpoises…
Distribution and habitat use of a cryptic small cetacean, the Burmeister’s porpoise, monitored from a small-scale fishery platform
Clay, Thomas A.; Mangel, Jeffrey C.; Alfaro-Shigueto, Joanna; Hodgson, David J.; Godley, Brendan J.
Frontiers in Marine Science (2018)
There is widespread evidence that small-scale fisheries (SSF) bycatch threatens many populations of small cetaceans, yet conservation efforts are often limited by a lack of basic knowledge regarding their abundance,…
Raising your voice: Evolution of narrow-band high-frequency signals in toothed whales (Odontoceti)
Galatius, Anders; Olsen, Morten Tange; Steeman, Mette Elstrup; Racicot, Rachel A.; Bradshaw, Catherine D; Kyhn, Line A.; Miller, Lee A.
Biological Journal of the Linnean Society (2018)
Cetaceans use sound for communication, navigation and finding prey. Most extant odontocetes produce broadband (BB) biosonar clicks covering frequency ranges from tens of kilohertz to 150–170 kHz. In contrast, the…
Choroid plexus cyst in a neonatal Burmeister’s porpoise (Phocoena spinipinnis)
Díaz-Delgado, J.; Groch, K. R.; Wiegand, M. W.; Secchi, E. R.; Réssio, R.; Natália, F. C. C.; Catão-Dias, J. L.
Journal of Comparative Pathology (2017)
Neuroectodermal developmental anomalies are reported rarely in cetaceans and central nervous system cysts are not described. We describe the gross, microscopical, histochemical and immunohistochemical features of a neuraxial myelencephalic cyst…
Comparative anatomy of the bony labyrinth of extant and extinct porpoises (Cetacea: Phocoenidae)
Racicot, Rachel A.; Gearty, William; Kohno, Naoki; Flynn, John J.
Biological Journal of the Linnean Society (2016)
The inner ear anatomy of cetaceans, now more readily accessible by means of nondestructive high-resolution X-ray computed tomographic (CT) scanning, provides a window into their acoustic abilities and ecological preferences.…
Morphology and variation in porpoise (Cetacea: Phocoenidae) cranial endocasts
Racicot, Rachel A.; Colbert, Matthew W.
The Anatomical Record (2013)
Evolution of endocranial anatomy in cetaceans is important from the perspective of echolocation ability, intelligence, social structure, and alternate pathways for circulation to the brain. Apart from the importance of…
