The present study summarized information on the morphometric characteristics and weight-length relationships (WLRs) of pregnant females, non-pregnant females and males of harbour porpoise, Phocoena phocoena (Linnaeus, 1758) along the Rize…
Asymmetric genitalia and lateralized mating behaviors occur in several taxa, yet whether asymmetric morphology in one sex correlates or coevolves with lateralized mating behavior in the other sex remains largely…
Absence of genetic differentiation is usually taken as an evidence of panmixia, but can also reflect other situations, including even nearly complete demographic independence among large-sized populations. Deciphering which situation…
Knowledge about reproductive parameters in male harbour porpoises such as testicular histology and germ cell maturation as well as seasonal changes in spermatogenesis is scarce. Thus, the aim of the…
...In the course of the pioneer virtopsy-driven stranding response program in Hong Kong (HK) waters, virtopsy using postmortem computed tomography (PMCT) has been implemented to augment conventional necropsy. A growing…
Contact zones between ecotypes are windows for understanding how species may react to climate changes. Here, we analysed the fine-scale genetic and morphological variation in harbour porpoises (Phocoena phocoena) around…
...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…
The mechanism by which odontocetes produce sound is unique among mammals. To gain insight into the physiological properties that support sound production in toothed whales, we examined myoglobin content ([Mb]),…
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…
