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…
Sustainability (2019)
We are among the scientists who have documented the environmental and ecological changes to the Upper Gulf of California following the reduction in the Colorado River’s flow. We object to…
Veterinary Research (2019)
Harbour porpoises (Phocoena phocoena) in the North Sea live in an environment heavily impacted by humans, the consequences of which are a concern for their health. Autopsies carried out on…
The Journal of the Acoustical Society of America (2019)
Harbour porpoises are well-suited for passive acoustic monitoring (PAM) as they produce highly stereotyped narrow-band high-frequency (NBHF) echolocation clicks. PAM systems must be coupled with a classification algorithm to identify…
Population Ecology (2019)
The narrow‐ridged finless porpoise Neophocaena asiaeorientalis is a small‐toothed whale with a coastal habitat and is sensitive to human activity. Aerial sighting surveys were conducted in 2012 to evaluate the…
Marine Biodiversity Records (2019)
Harbour porpoise (Phocoena phocoena) is listed under the Annex II of the European Habitats Directive (Directive 92/43/CEE) and Member States are required to designate special areas of conservation to protect…
Aquatic Mammals (2019)
Odontocetes are usually reported giving birth to calves in breech position (fluke-first). Cephalic position (head-first) is less frequently observed and, therefore, is considered to be abnormal for the parturition. However,…
Wageningen Marine Research Reports (2019)
Harbour porpoises (Phocoena phocoena) are regularly monitored to assess how they are impacted by the construction and operation of offshore wind farms. A suitable method to do this is passive…
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…
The Journal of the Acoustical Society of America (2019)
Algorithms are presented for the accurate time of arrival difference estimation of high frequency narrow band echolocation clicks from Harbor Porpoise. These clicks typically have a center frequency of around…
