Scientific Reports (2017)
Understanding demographic trends and patterns of gene flow in an endangered species is crucial for devising conservation strategies. Here, we examined the extent of population structure and recent evolution of…
Behavioral responses of a harbor porpoise (Phocoena phocoena) to sounds from an acoustic porpoise deterrent
Kastelein, Ronald A.; Huybrechts, Janne; Covi, Jennifer; Helder-Hoek, Lean
Aquatic Mammals (2017)
To determine whether sounds from the FaunaGuard Porpoise Module or Acoustic Porpoise Deterrent-01 (APD-01) can deter harbor porpoises (Phocoena phocoena) far enough away from an offshore pile driving site to…
Long-term association between a solitary common dolphin (Delphinus delphis delphis) and a harbour porpoise (Phocoena phocoena)
Ryan, Conor; Macleod, Greig; Dinsdale, Cameron; Cook, Stuart
Aquatic Mammals (2017)
(...)The occurrence of solitary dolphins (i.e., those in isolation from conspecifics) is well-documented in the case of bottlenose dolphins (Tursiops truncatus) along the western seaboard of northern Europe (Lockyer, 1990);…

Milani, C. B.; Vella, A.; Vidoris, P.; Christidis, A.; Koutrakis, E.; Frantzis, A.; Miliou, A.; Kallianiotis, A.
Journal of the Marine Biological Association of the United Kingdom (2017)
Cetacean stranding reports in the North Aegean Sea were recorded since 1998 from Strimonikos Gulf in Chalkidiki up to Alexandroupoli on the Turkish border and in a few northern Aegean…
Directional acoustic wave manipulation by a porpoise via multiphase forehead structure
Zhang, Yu; Song, Zhongchang; Wang, Xianyan; Cao, Wenwu; Au, Whitlow W. L.
Physical Review Applied (2017)
Porpoises are small-toothed whales, and they can produce directional acoustic waves to detect and track prey with high resolution and a wide field of view. Their sound-source sizes are rather…
Return of harbor porpoises (Phocoena phocoena) to San Francisco Bay
Stern, S. Jonathan; Keener, William; Szczepaniak, Isidore D.; Webber, Marc A.
Aquatic Mammals (2017)
Harbor porpoises (Phocoena phocoena) were rarely seen in San Francisco Bay prior to 2008 despite numerous marine mammal search efforts beginning in the 1970s. The species inhabited the bay historically…
Habitat-based density models for three cetacean species off southern California illustrate pronounced seasonal differences
Becker, Elizabeth A.; Forney, Karin A.; Thayre, Bruce J.; Debich, Amanda J.; Campbell, Gregory S.; Whitaker, Katherine; Douglas, Annie B.; Gilles, Anita; Hoopes, Ryan; Hildebrand, John A.
Frontiers in Marine Science (2017)
Managing marine species effectively requires spatially and temporally explicit knowledge of their density and distribution. Habitat-based density models, a type of species distribution model (SDM) that uses habitat covariates to…
Linear transect surveys of abundance and density of cetaceans in the area near the Dzharylgach Island in the north-western Black Sea
Gladilina, E. V.; Vishnyakova, K. A.; Neprokin, O. O.; Ivanchikova, Yu. F.; Derkacheva, T. A.; Kryukova, A. A.; Savenko, O. V.; Gol’din, P. E.
Vestnik Zoologii (2017)
The first assessment of cetacean density and abundance by linear transect survey was conducted in 2016 and 2017 in the shallowest coastal area of the Ukrainian sector of the north-western…
Long-term effectiveness of pingers on a small population of finless porpoises in Japan
Amano, M.; Kusumoto, M.; Abe, M.; Akamatsu, T.
Endangered Species Research (2017)
Finless porpoises Neophocaena spp. are under pressure from various anthropogenic impacts due to their coastal habitat. Net fishery bycatch is considered a major risk for the populations around Japan, and…
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…
