To provide hormone evidence on reproductive seasonality and maturity of the Yangtze finless porpoise, the authors monitored the monthly variations of serum reproductive hormones of a male Yangtze finless porpoise…
Reproductive behaviors are poorly known for the Yangtze finless porpoise Neophocaena phocaenoides asiaeorientalis. In this study, the parentage of an isolated Yangtze finless porpoise population inhabiting the Yangtze Tian-e-Zhou Baiji…
Natural hybridization occurs rarely in mammals compared with other taxonomic groups of animals. Cetaceans appear unique among mammals in exhibiting striking karyological uniformity, which suggests that they have the potential…
Stranded harbour porpoises were analysed to investigate differences in stranding patterns along the North and Baltic Sea coasts of Schleswig-Holstein, Germany. A total of 1,015 stranded or bycaught harbour porpoises…
This report summarises the available knowledge on odontocete (toothed whale) distribution, behaviour, migration and threats and was compiled for the Bonn Secretariat of CMS.
A total of 1,268 harbour porpoises were obtained from fishing nets in Icelandic coastal waters from September to June in the years 1991 to 1997. Foetal sex ratio was 1.2:1…
Biological parameters for harbour porpoises are reviewed throughout their range in the North Atlantic. Most information is based on studies of a combination of directed catches, bycatches and strandings. All…
The harbour porpoises kept at the Fjord & Bælt since April 1997 offer a unique opportunity to gain a better understanding of the reproductive function in harbour porpoises, especially in…
Species Information The harbour porpoise is one of the smallest cetacean species, born at 80-90 cm and only occasionally reaching lengths of close to 2 m. In general, harbour porpoises…
In this study, we analyse some aspects of the macro- and microscopical appearance of gonads of harbour porpoises (Phocoena phocoena) from Icelandic coastal waters. Sampling of animals bycaught in gillnets…
