Records of harbour porpoise (Phocoena phocoena) in the mouth of the Douro River (northern Portugal) with presence of an anomalous white individual

Gil, Ágatha; Correia, Ana M.; Sousa-Pinto, Isabel
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…

Estimation of population size and trends for highly mobile species with dynamic spatial distributions

Boyd, Charlotte; Barlow, Jay; Becker, Elizabeth A.; Forney, Karin A.; Gerrodette, Tim; Moore, Jeffrey E.; Punt, André E.
Diversity and Distributions (2017)

Conventional spatial density models assume a constant relationship between densities and habitat covariates over some time period, typically a survey season. The estimated population size must change whenever total habitat…

Abundance decline in the narrow‐ridged finless porpoise population off the Pacific coast of eastern Japan

Shirakihara, Kunio; Nakahara, Fumio; Shinohara, Masanori; Shirakihara, Miki; Hiramatsu, Kazuhiko; Irie, Takahiro
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…

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.…

Harbour porpoise distribution can vary at small spatiotemporal scales in energetic habitats

Benjamins, Steven; van Geel, Nienke; Hastie, Gordon; Elliott, Jim; Wilson, Ben
Deep Sea Research Part II: Topical Studies in Oceanography (2017)

Marine habitat heterogeneity underpins species distribution and can be generated through interactions between physical and biological drivers at multiple spatiotemporal scales. Passive acoustic monitoring (PAM) is used worldwide to study…

Habitat succession of the Yangtze finless porpoise in Poyang Lake under the changing hydrodynamic and feeding environment

Han, Yong; Sun, Zhiyu; Fang, Hongwei; Bai, Sen; Huang, Lei; He, Guojian
Ecological Modelling (2020)

Poyang Lake, located in the middle and lower reaches of the Yangtze River, is the largest freshwater lake in China and the most important habitat for the Yangtze finless porpoise.…

Basin-scale distribution of harbour porpoises in the Baltic Sea provides basis for effective conservation actions

Carlén, Ida; Thomas, Len; Carlström, Julia; Amundin, Mats; Teilmann, Jonas; Tregenza, Nick; Tougaard, Jakob; Koblitz, Jens C.; Sveegaard, Signe; Wennerberg, Daniel; Loisa, Olli; Dähne, Michael; Brundiers, Katharina; Kosecka, Monika; Kyhn, Line Anker; Ljungqvist, Cinthia Tiberi; Pawliczka, Iwona; Koza, Radomil; Arciszewski, Bartlomiej; Galatius, Anders; Jabbusch, Martin; Laaksonlaita, Jussi; Niemi, Jussi; Lyytinen, Sami; Gallus, Anja; Benke, Harald; Blankett, Penina; Skóra, Krzysztof E.; Acevedo-Gutiérrez, Alejandro
Biological Conservation (2018)

Knowledge on spatial and seasonal distribution of species is crucial when designing protected areas and implementing management actions. The Baltic Proper harbour porpoise (Phocoena phocoena) population is critically endangered, and…
