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…
Abundance and seasonality of Dall’s porpoise (Phocoenoides dalli) in southeast Alaska
Jefferson, T. A.; Dahlheim, M. E.; Zerbini, A. N.; Waite, J. M.; Kennedy, A. S.
NOAA Technical Memorandum NMFS-AFSC-385 (2019)
Little is known about Dall’s porpoise (Phocoenoides dalli) population biology in Southeast Alaska. Here we present the first abundance estimates for Dall’s porpoise in the waters of Southeast Alaska. We…
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,…
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…
Long-term passive acoustic monitoring revealed seasonal and diel patterns of cetacean presence in the Istanbul Strait
Dede, Ayhan; Öztürk, Ayaka Amaha; Akamatsu, Tomonari; Tonay, Arda M.; Öztürk, Bayram
Journal of the Marine Biological Association of the United Kingdom (2013)
The Istanbul Strait (Bosphorus) is a part of the Turkish Straits System, connecting the Aegean Sea and the Black Sea. There are three cetacean species in the Strait, namely the…
Habitat preferences among three top predators inhabiting a degraded ecosystem, the Black Sea
Sánchez-Cabanes, Alicia; Nimak-Wood, Maja; Harris, Nicola; de Stephanis, Renaud
Scientia Marina (2017)
This study investigated whether there is evidence of widespread niche partitioning based on environmental factors in the Black Sea and tested the hypothesis that physiographic factors may be employed as…
Where is the risk? Integrating a spatial distribution model and a risk assessment to identify areas of cetacean interaction with fisheries in the northeast Atlantic
Breen, Patricia; Brown, Susie; Reid, David; Rogan, Emer
Ocean & Coastal Management (2017)
Throughout their range, marine mammals are vulnerable to incidental capture in fishing gear. Bycatch is a particularly important issue for cetaceans, which generally have lower potential rates of population growth…
Diurnal variation in harbour porpoise detection – Potential implications for management
Williamson, L. D.; Brookes, K. L.; Scott, B. E.; Graham, I. M.; Thompson, P. M.
Marine Ecology Progress Series (2017)
Robust information on animal distributions and foraging behaviour is required to target management and conservation measures for protected species and populations. Visual survey data are commonly used to model these…
Year-round spatiotemporal distribution of harbour porpoises within and around the Maryland wind energy area
Wingfield, Jessica E.; O’Brien, Michael; Lyubchich, Vyacheslav; Roberts, Jason J.; Halpin, Patrick N.; Rice, Aaron N.; Bailey, Helen
PLOS ONE (2017)
Offshore windfarms provide renewable energy, but activities during the construction phase can affect marine mammals. To understand how the construction of an offshore windfarm in the Maryland Wind Energy Area…
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…
