We succinctly review and document new cases of diseases of the skin and the skeletal system and external traumata in cetaceans from Ecuador, Colombia, Peru, Chile, Argentina, Uruguay, Brazil, and…
Mate guarding in male Dall’s porpoises (Phocoenoides dalli)
Willis, Pamela M.; Dill, Lawrence M.
Ethology (2007)
Mate guarding, whereby a male closely attends and defends a fertile female from extra-pair matings, is one mating tactic males of many species use to protect their paternity. Although female…

Tonay, A. M.; Dede, A.; Öztürk, A. A.; Öztürk, B.
Rapports et Procès-Verbaux des Réunions de la Commission Internationale pour l'Exploration Scientifique de la Mer Méditerranée (2007)
The study was based on stomach content from 42 harbour porpoises bycaught or stranded between April to June in 2002 and 2003, on the Turkish western Black Sea coast. Seven…
Perception of low-frequency acoustic signals by a harbour porpoise (Phocoena phocoena) in the presence of simulated offshore wind turbine noise
Lucke, Klaus; Lepper, Paul A.; Hoeve, Bert; Everaarts, Eligius; van Elk, Niels; Siebert, Ursula
Aquatic Mammals (2007)
Using auditory evoked potential (AEP) methods, a study was conducted on a harbour porpoise (Phocoena phocoena) at the Dolfinarium Harderwijk in The Netherlands. The study measured the audible range of…
Responses of cetaceans to anthropogenic noise
Nowacek, Douglas P.; Thorne, Lesley H.; Johnston, David W.; Tyack, Peter L.
Mammal Review (2007)
1. Since the last thorough review of the effects of anthropogenic noise on cetaceans in 1995, a substantial number of research reports has been published and our ability to document…
The ontogeny of echolocation in a Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis)
Li, Songhai; Wang, Ding; Wang, Kexiong; Xiao, Jianqiang; Akamatsu, Tomonari
The Journal of the Acoustical Society of America (2007)
Acoustic and concurrent behavioral data from one neonatal male Yangtze finless porpoise (Neophocaena phocaenoides asiaeorientalis) in captivity were presented. The calf click train was first recorded at 22 days postnatal,…
Comparison of echolocation behaviour between coastal and riverine porpoises
Akamatsu, Tomonari; Teilmann, Jonas; Miller, Lee A.; Tougaard, Jakob; Dietz, Rune; Wang, Ding; Wang, Kexiong; Siebert, Ursula; Naito, Yasuhiko
Deep Sea Research Part II: Topical Studies in Oceanography (2007)
Echolocation behaviour of a harbor porpoise and six finless porpoises was recorded in open-water systems using acoustic data loggers (A-tag). In total 1359 click trains were recorded during 4.6 h…
Intermingling of dalli-type Dall’s porpoises into a wintering truei-type population off Japan: Implications from color patterns
Amano, Masao; Hayano, Azusa
Marine Mammal Sci (2007)
There are two major color morphs, truei and dalli types, of the Dall's porpoise and the latter includes two minor morphs. A small number of dalli types are found among…
Decrease stress; train your animals: The effect of handling methods on cortisol levels in harbour porpoises (Phocoena phocoena) under human care
Desportes, Geneviève; Buholzer, Lisette; Anderson-Hansen, Kirstin; Blanchet, Marie-Anne; Acquarone, Mario; Shephard, Gwyneth; Brando, Sabrina; Vossen, Arndt; Siebert, Ursula
Aquatic Mammals (2007)
Circulating cortisol levels are accepted as a sensitive indicator of acute stress in marine mammals, particularly in relation with capture and handling. The present study provides the first long-term monitoring…
Cytokines and acute phase proteins as markers for infection in harbor porpoises (Phocoena phocoena)
Fonfara, S.; Siebert, U.; Prange, A.
Marine Mammal Sci (2007)
(...) Impairment of immune function and inflammatory incidences in marine mammals are generally difficult to detect (King et al. 1996, Zeneto-Savin et al. 1997, Funke et al. 2003). Therefore, markers…
