Marine Biology (2018)
Determining the drivers that are responsible for the fine-scale distribution of cetacean species is fundamental to understand better how they respond to changes in their environment. We utilized information theoretic…
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…
Conservation plan for the harbour porpoise Phocoena phocoena in The Netherlands: Towards a favourable conservation status
Camphuysen, Kees C. J.; Siemensma, Marije L.
NIOZ Reports (2011)
- This is a conservation plan for the Harbour Porpoise Phocoena phocoena based on the current seasonal occurrence and abundance of porpoises within waters under Dutch jurisdiction. - The conservation…
Environmental drivers of harbour porpoise fine-scale movements
van Beest, Floris M.; Teilmann, Jonas; Dietz, Rune; Galatius, Anders; Mikkelsen, Lonnie; Stalder, Dominique; Sveegaard, Signe; Nabe-Nielsen, Jacob
Marine Biology (2018)
Quantifying intraspecific variation in movement behaviour of marine predators and the underlying environmental drivers is important to inform conservation management of protected species. Here, we provide the first empirical data…
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.…
Using passive acoustic monitoring to investigate the occurrence of cetaceans in a protected marine area in northwest Ireland
Todd, Nicole R. E.; Cronin, Michelle; Luck, Cian; Bennison, Ashley; Jessopp, Mark; Kavanagh, Ailbhe S.
Estuarine, Coastal and Shelf Science (2020)
Under the EU Habitats Directive, cetacean species must be maintained at favourable conservation status in European waters. Whether this is achieved via protected area designation, curtailment of activities such as…
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…
Stable oxygen isotopes reveal habitat use by marine mammals in the Río de la Plata estuary and adjoining Atlantic Ocean
Drago, Massimiliano; Valdivia, Meica; Bragg, Daniel; González, Enrique M.; Aguilar, Alex; Cardona, Luis
Estuarine, Coastal and Shelf Science (2020)
Detailed knowledge on habitat use by marine mammals is critical for understanding their ecological role and for adequate management. Here, we assess the habitat use patterns of thirteen species of…
