Journal of Biogeography, Volume 52, Issue 8, August 2025.ABSTRACT Aim During glacial periods, highly mobile species often shifted to warmer, ice‐free regions known as refugia, which frequently maintained higher genetic diversity than newly colonised areas after glacial retreat. We analyse complete mitogenome sequences from 11 killer whale samples in Nemuro Strait to test the hypothesis that waters around ...

Craniogenetic studies in Sus scrofa: With emphasis on the ‘orbitosphenoid’ problem
The Anatomical Record, Volume 308, Issue 7, Page 1931-1943, July 2025.Abstract The orbitosphenoid is a skeletal element of the endocranium of extant mammals. However, it has also been described in many of their fossil ancestors. Craniogenetic studies show that it is composed of two types of bone: first, the cartilaginous ala orbitalis and parts of the trabecular plate are transformed by endochondral ossification; second,

Steno bredanensis (Cetacea: Delphinidae) [PDF]
Mammalian Species, 2011 Steno bredanensis (Cuvier in Lesson, 1828) is a small odontocete commonly called the rough-toothed dolphin. A slender, gray dolphin with a slightly darker cape, this species is most easily distinguished from other small delphinids by a gradually sloping forehead and a long rostrum. It is the only species in the genus Steno. Despite reports of sightings

Marine Mammal Science, Volume 41, Issue 3, July 2025.ABSTRACT Beaked whales (Cetacea; Ziphiidae), one of the most diverse families of cetaceans, can be identified by species‐specific, frequency‐modulated echolocation signals. Of the 24 known species of beaked whales, over half have been assigned a unique signal type. A novel echolocation pulse belonging to an unknown beaked whale species was recorded off
