Raising your voice: Evolution of narrow-band high-frequency signals in toothed whales (Odontoceti)

Galatius, Anders; Olsen, Morten Tange; Steeman, Mette Elstrup; Racicot, Rachel A.; Bradshaw, Catherine D; Kyhn, Line A.; Miller, Lee A.
Biological Journal of the Linnean Society (2018)

Cetaceans use sound for communication, navigation and finding prey. Most extant odontocetes produce broadband (BB) biosonar clicks covering frequency ranges from tens of kilohertz to 150–170 kHz. In contrast, the…

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…

Differential population dynamics of a coastal porpoise correspond to the fishing effort in a large estuarine system

Lin, Wenzhi; Karczmarski, Leszek; Li, Jun; Chan, Stephen C. Y.; Guo, Lang; Wu, Yuping
Aquatic Conservation: Marine and Freshwater Ecosystems (2019)

The finless porpoise (genus Neophocaena) is susceptible to fishery‐caused mortality, and its numbers are thought to be in decline across its entire range. However, population demographics have rarely been quantified…

Analysis of the bacterial diversity in the fecal material of the endangered Yangtze finless porpoise, Neophocaena phocaenoides asiaeorientalis

McLaughlin, Richard William; Chen, Minmin; Zheng, Jinsong; Zhao, Qingzhong; Wang, Ding
Molecular Biology Reports (2011)

The aim of this study was to determine the bacteria present in the fecal material of the endangered Yangtze finless porpoise, Neophocaena phocaenoides asiaeorientalis. Fecal samples were collected from 12…

Levels of polychlorinated biphenyls are still associated with toxic effects in harbor porpoises (Phocoena phocoena) despite having fallen below proposed toxicity thresholds

Environmental Science & Technology (2020)

Polychlorinated biphenyls (PCBs) are toxic, persistent, and lipophilic chemical compounds that accumulate to high levels in harbor porpoises (Phocoena phocoena) and other cetaceans. It is important to monitor PCBs in…

Tissue-specific accumulation and body burden of parabens and their metabolites in small cetaceans

Jeong, Yunsun; Xue, Jingchuan; Park, Kyum Joon; Kannan, Kurunthachalam; Moon, Hyo-Bang
Environmental Science & Technology (2018)

Parabens have been of global concern due to their endocrine disrupting properties. However, few studies have reported tissue-specific distribution of parabens in wildlife. In this study, we measured parabens and…

Estimating effective detection area of static passive acoustic data loggers from playback experiments with cetacean vocalisations

Nuuttila, Hanna K.; Brundiers, Katharina; Dähne, Michael; Koblitz, Jens C.; Thomas, Len; Courtene‐Jones, Winnie; Evans, Peter G. H.; Turner, John R.; Bennell, Jim D.; Hiddink, Jan G.
Methods in Ecology and Evolution (2018)

Passive acoustic monitoring (PAM) is used for many vocal species. However, few studies have quantified the fraction of vocalisations captured, and how animal distance and sound source level affect detection…
