Biological Conservation (2016)
The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis) is the world's only freshwater porpoise and is endemic to the Yangtze River. However, it is now Critically Endangered, with its long-term survival…
Harbor porpoise (Phocoena phocoena) recovery in the inland waters of Washington: Estimates of density and abundance from aerial surveys, 2013–2015
Jefferson, Thomas A.; Smultea, Mari A.; Courbis, Sarah S.; Campbell, Gregory S.
Canadian Journal of Zoology (2016)
The harbor porpoise (Phocoena phocoena (L., 1758)) used to be common in Puget Sound, Washington, but virtually disappeared from these waters by the 1970s. We conducted systematic aerial line-transect surveys…
Seventh Meeting of the Comité Internacional para la Recuperación de la Vaquita
CIRVA
(2016)
EXTINCTION IS IMMINENT CIRVA reviewed the 2015 population survey results, which showed that only about 60 vaquitas remained at the beginning of the emergency 2-year partial gillnet ban. CIRVA also…
ASCOBANS Recovery Plan for Baltic Harbour Porpoises – Jastarnia Plan (2016 Revision)
(2016)
This is the ASCOBANS species action plan for what is called Baltic harbour porpoise population primarily inhabiting the Baltic Proper. The population’s abundance has recently been estimated at only 497…
Echolocation detections and digital video surveys provide reliable estimates of the relative density of harbour porpoises
Williamson, Laura D.; Brookes, Kate L.; Scott, Beth E.; Graham, Isla M.; Bradbury, Gareth; Hammond, Philip S.; Thompson, Paul M.
Methods in Ecology and Evolution (2016)
1. Robust estimates of the density or abundance of cetaceans are required to support a wide range of ecological studies and inform management decisions. Considerable effort has been put into…
Noise mitigation during pile driving efficiently reduces disturbance of marine mammals
Nehls, Georg; Rose, Armin; Diederichs, Ansgar; Bellmann, Michael; Pehlke, Hendrik
Advances in Experimental Medicine and Biology (2016)
Acoustic monitoring of harbor porpoises (Phocoena phocoena L., 1758) indicated a strongly reduced disturbance by noise emitted by pile driving for offshore wind turbine foundations insulated by a big bubble…
Fishers’ knowledge as an information source to investigate bycatch of marine mammals in the South China Sea
Liu, M.; Lin, M.; Turvey, S. T.; Li, S.
Animal Conservation (2016)
Bycatch mortality is a significant driver of marine mammal population declines. However, there is little information available on patterns or magnitude of bycatch mortality in many heavily fished Asian marine…
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…
