PLOS ONE (2017)

The harbour porpoise is the only cetacean species native to German waters. Since human pressures are suggested to shorten their reproductive lifespan, basic knowledge on reproduction is strongly required. One…

...The Yangtze finless porpoise (Neophocaena asiaeorientalis asiaeorientalis), endemic to the middle and lower reaches of the Yangtze River and the adjoining Poyang and Dongting lakes (Gao and Zhou 1993), is…

Genital interactions during simulated copulation among marine mammals

Orbach, Dara N.; Kelly, Diane A.; Solano, Mauricio; Brennan, Patricia L. R.
Proceedings of the Royal Society B: Biological Sciences (2017)

Genitalia are morphologically variable across many taxa and in physical contact during intromission, but little is known about how variation in form correlates with function during copulation. Marine mammals offer…

Characterization of milk composition in narrow-ridged finless porpoises (Neophocaena asiaeorientalis) at different lactation stages

Zoology Conference 2017 (2016)

The increased number of juvenile and newborn harbour porpoise strandings along the German Baltic coasts in summer provides evidence for a possible local calving and nursing ground in this area.…

Saving the Yangtze finless porpoise: Time is rapidly running out
