(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…
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…
Abundance and distribution of cetaceans in the Gulf of Alaska
Rone, Brenda K.; Zerbini, Alexandre N.; Douglas, Annie B.; Weller, David W.; Clapham, Phillip J.
Marine Biology (2017)
To effectively protect and manage marine mammals, contemporary information on their abundance and distribution is essential. Several factors influence present-day insight including the accessibility of the study area and the…
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…
Coming of age: Do female harbour porpoises (Phocoena phocoena) from the North Sea and Baltic Sea have sufficient time to reproduce in a human influenced environment?
Kesselring, Tina; Viquerat, Sacha; Brehm, Ralph; Siebert, Ursula
PLOS ONE (2017)
The harbour porpoise is the only cetacean species native to German waters. Since human pressures are suggested to shorten their reproductive lifespan, basic knowledge on reproduction is strongly required. One…
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.…
Bubble curtains attenuate noise from offshore wind farm construction and reduce temporary habitat loss for harbour porpoises
Dähne, M.; Tougaard, J.; Carstensen, J.; Rose, A.; Nabe-Nielsen, J.
Marine Ecology Progress Series (2017)
Effects of constructing the DanTysk offshore wind farm (German Bight, 80 turbines, 6 m diameter foundations) were studied by passive acoustic monitoring of pile-driving noise and harbour porpoise Phocoena phocoena…
Genetic footprint of population fragmentation and contemporary collapse in a freshwater cetacean
Chen, Minmin; Fontaine, Michael C.; Ben Chehida, Yacine; Zheng, Jinsong; Labbé, Frédéric; Mei, Zhigang; Hao, Yujiang; Wang, Kexiong; Wu, Min; Zhao, Qingzhong; Wang, Ding
Scientific Reports (2017)
Understanding demographic trends and patterns of gene flow in an endangered species is crucial for devising conservation strategies. Here, we examined the extent of population structure and recent evolution of…
Behavioral responses of a harbor porpoise (Phocoena phocoena) to sounds from an acoustic porpoise deterrent
Kastelein, Ronald A.; Huybrechts, Janne; Covi, Jennifer; Helder-Hoek, Lean
Aquatic Mammals (2017)
To determine whether sounds from the FaunaGuard Porpoise Module or Acoustic Porpoise Deterrent-01 (APD-01) can deter harbor porpoises (Phocoena phocoena) far enough away from an offshore pile driving site to…
Long-term association between a solitary common dolphin (Delphinus delphis delphis) and a harbour porpoise (Phocoena phocoena)
Ryan, Conor; Macleod, Greig; Dinsdale, Cameron; Cook, Stuart
Aquatic Mammals (2017)
(...)The occurrence of solitary dolphins (i.e., those in isolation from conspecifics) is well-documented in the case of bottlenose dolphins (Tursiops truncatus) along the western seaboard of northern Europe (Lockyer, 1990);…
