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…


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…


Distribution of three sympatric cetacean species off the coast of the central-western Gulf of Thailand

Jutapruet, Suwat; Intongcome, Atichat; Wang, Xianyan; Kittiwattanawong, Kongkiat; Huang, Shiang-Lin
Aquatic Mammals (2017)

Baseline data on the distribution patterns of animals disclose the dynamic function of habitat use as it relates to the accessibility of prey, social interactions, predator-prey interactions, and inter-habitat-patch mobility.…


Marine mammal sightings around oil and gas installations in the central North Sea

Delefosse, Matthieu; Rahbek, Malene Louise; Roesen, Lars; Clausen, Karin Tubbert
Journal of the Marine Biological Association of the United Kingdom (2017)

Relatively little is known about the distribution and diversity of marine mammals around offshore anthropogenic structures. We present results obtained from incidental sightings of marine mammals around oil and gas…


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…


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,…
