Endangered Species Research (2013)
Active sound emitters (‘pingers’) are used in several gillnet fisheries to reduce bycatch of small cetaceans, and/or to reduce depredation by dolphins. Here, we review studies conducted to determine how…
Sexual dimorphism of Dall’s porpoise and harbor porpoise skulls
Frandsen, Marie Schou; Galatius, Anders
Mammalian Biology - Zeitschrift für Säugetierkunde (2013)
To evaluate and quantify sexual dimorphism of skull shape and assess the ontogenetic background for differences, samples of 134 harbor porpoise (Phocoena phocoena) and 85 Dall's porpoise (Phocoenoides dalli) were…
Comparative morphology of porpoise (Cetacea: Phocoenidae) pterygoid sinuses: Phylogenetic and functional implications
Racicot, Rachel A.; Berta, Annalisa
Journal of Morphology (2012)
High-resolution X-ray computed tomographic scans were used to examine pterygoid sinus morphology within extant porpoise species and one delphinid (Tursiops truncatus), in order to consider: 1) intraspecific and interspecific variation…
The modulation rate transfer function of a harbour porpoise (Phocoena phocoena)
Linnenschmidt, Meike; Wahlberg, Magnus; Damsgaard Hansen, Janni
Journal of Comparative Physiology A (2012)
During echolocation, toothed whales produce ultrasonic clicks at extremely rapid rates and listen for the returning echoes. The auditory brainstem response (ABR) duration was evaluated in terms of latency between…
Organization and number of orexinergic neurons in the hypothalamus of two species of Cetartiodactyla: A comparison of giraffe (Giraffa camelopardalis) and harbour porpoise (Phocoena phocoena)
Dell, Leigh-Anne; Patzke, Nina; Bhagwandin, Adhil; Bux, Faiza; Fuxe, Kjell; Barber, Grace; Siegel, Jerome M.; Manger, Paul R.
Journal of Chemical Neuroanatomy (2012)
The present study describes the organization of the orexinergic (hypocretinergic) neurons in the hypothalamus of the giraffe and harbour porpoise – two members of the mammalian Order Cetartiodactyla which is…
The ecological role of the vaquita, Phocoena sinus, in the ecosystem of the northern Gulf of California
Riofrío-Lazo, Marjorie; Arreguín-Sánchez, Francisco; Zetina-Rejón, Manuel; Escobar-Toledo, Fabián
Ecosystems (2012)
From an ecosystem management perspective, analysis of the functional roles of species is a challenge. It is valuable to determine which species are irreplaceable within a given community based on…
Harbour porpoises (Phocoena phocoena) and wind farms: a case study in the Dutch North Sea
Scheidat, Meike; Tougaard, Jakob; Brasseur, Sophie; Carstensen, Jacob; van Polanen Petel, Tamara; Teilmann, Jonas; Reijnders, Peter
Environmental Research Letters (2011)
The rapid increase in development of offshore wind energy in European waters has raised concern for the possible environmental impacts of wind farms. We studied whether harbour porpoise occurrence has…
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…
Geographic variation of skeletal ontogeny and skull shape in the harbour porpoise (Phocoena phocoena)
Galatius, A.; Gol’din, P. E.
Canadian Journal of Zoology (2011)
All extant porpoise species show paedomorphic skeletal traits. These traits are hypothesized to be connected with rapid growth to reproductive size and could thus show geographic variation according to ecological…
Investigations of thyroid and stress hormones in free-ranging and captive harbor porpoises (Phocoena phocoena): A pilot study
Siebert, Ursula; Pozniak, Blazej; Anderson Hansen, Kirstin; Nordstrom, Gwyneth; Teilmann, Jonas; van Elk, Niels; Vossen, Arndt; Dietz, Rune;
Aquatic Mammals (2011)
Increasing anthropogenic activities in the marine environment are potential threats to the health of harbor porpoises by causing unnatural continuous stress to the animals. The present study was a first…
