The Dire Status of the Vaquita Has Worsened Analysis of the 2016 Acoustic Monitoring Program data has shown that almost half of the remaining vaquita population was lost between 2015…
Mixing of porpoise ecotypes in southwestern UK waters revealed by genetic profiling
Fontaine, Michaël C.; Thatcher, Oliver; Ray, Nicolas; Piry, Sylvain; Brownlow, Andrew; Davison, Nicholas J.; Jepson, Paul; Deaville, Rob; Goodman, Simon J.
Royal Society Open Science (2017)
Contact zones between ecotypes are windows for understanding how species may react to climate changes. Here, we analysed the fine-scale genetic and morphological variation in harbour porpoises (Phocoena phocoena) around…
Harbor porpoise, Phocoena phocoena, abundance estimation for California, Oregon, and Washington: I. Ship surveys
Barlow, J.
Fishery Bulletin (1988)
The density and total population size of harbor porpoise along the coasts of California, Oregon, and Washington are estimated from ship surveys using line transect methods. Surveys were completed between…
Harbor porpoise, Phocoena phocoena, abundance estimation for California, Oregon, and Washington: II. Aerial surveys
Barlow, Jay; Oliver, Charles W.; Jackson, Terry D.; Taylor, Barbara L.
Fishery Bulletin (1988)
We conducted aerial surveys in September 1984 and September and October 1985 to determine the abundance of harbor porpoise along the coasts of California, Oregon, and Washington. Two observers and…
Comparison of dolphins’ body and brain measurements with four other groups of cetaceans reveals great diversity
Ridgway, Sam H.; Carlin, Kevin P.; Van Alstyne, Kaitlin R.; Hanson, Alicia C.; Tarpley, Raymond J.
Brain, Behavior and Evolution (2016)
We compared mature dolphins with 4 other groupings of mature cetaceans. With a large data set, we found great brain diversity among 5 different taxonomic groupings. The dolphins in our…
Characterization of milk composition in narrow-ridged finless porpoises (Neophocaena asiaeorientalis) at different lactation stages
Zeng, Xianyuan; Huang, Shiang-lin; Qian, Zhengyi; Hao, Yujiang; Wang, Ding; Ji, Junhua; Nabi, Ghulam
Marine Mammal Science (2017)
Lactation plays a vital role in reproductive success, evolving with ecological adaptations of mammalian life histories. Knowledge of the lactation process in odontocetes is scarce and limited to a handful…
Using environmental DNA to assess population-wide spatiotemporal reserve use
Stewart, Kathryn; Ma, Hongjuan; Zheng, Jinsong; Zhao, Jianfu
Conservation Biology (2017)
Scientists increasingly rely on protected areas to assist in biodiversity conservation, yet the efficacy of these areas are rarely systematically assessed, often as a byproduct of underfunding, particularly in developing…
Long-term tag retention on two species of small cetaceans
Heide-Jørgensen, Mads Peter; Nielsen, Nynne H.; Teilmann, Jonas; Leifsson, Páll S.
Marine Mammal Science (2017)
The effects of tagging on small cetaceans are difficult to assess due to logistical difficulties in recapturing the whales. In this study two narwhals, Monodon monoceros, and five harbor porpoises,…
Don’t forget the porpoise: Acoustic monitoring reveals fine scale temporal variation between bottlenose dolphin and harbour porpoise in Cardigan Bay SAC
Nuuttila, Hanna K.; Courtene-Jones, Winnie; Baulch, Sarah; Simon, Malene; Evans, Peter G. H.
Marine Biology (2017)
Populations of bottlenose dolphin and harbour porpoise inhabit Cardigan Bay, which was designated a Special Area of Conservation (SAC), with bottlenose dolphin listed as a primary feature for its conservation…
Inter-species differences in polychlorinated biphenyls patterns from five sympatric species of odontocetes: Can PCBs be used as tracers of feeding ecology?
Méndez-Fernandez, Paula; Simon-Bouhet, Benoit; Bustamante, Paco; Chouvelon, Tiphaine; Ferreira, Marisa; López, Alfredo; Moffat, Colin F.; Pierce, Graham J.; Russell, Marie; Santos, Maria B.; Spitz, Jérôme; Vingada, José V.; Webster, Lynda; Read, Fiona L.; González, Angel F.; Caurant, Florence
Ecological Indicators (2017)
Concentrations of thirty two polychlorinated biphenyls (PCBs) were determined in the blubber of five sympatric species of odontocetes stranded or by-caught along the Northwest coast of the Iberian Peninsula: common…
