Genetic architectures of postmating isolation and morphology of two highly diverged rockfishes (genus Sebastes).

Postmating isolation is thought to be an important driver of the late stages of speciation. However, relatively little is empirically known about the process compared with other isolating mechanisms that drive the early stages of speciation, especially in non-model organisms. We characterized the genetic architecture of postmating isolation between 2 rockfishes, Sebastes schlegelii and S.

An unexpected distribution record of the cold water fish Pholis fangi (Pholidae) from southern Taiwan.

Gunnel species (family Pholidae), characterized by an elongated bar-like body and usually found in shallow coastal waters, are mostly restricted to temperate to subarctic waters in the Northern Pacific Ocean, although some in the Western Pacific are distributed southward to the northern East China Sea. Despite the absence of previous records from subtropical and tropical waters, a single specimen of the fish family Pholidae was recently trawled off southwestern Taiwan. Examination on the morphological characteristics and DNA barcoding revealed this is a Pholis fangi (Wang Wang 1935), a species previously recorded only from cold waters in the Bohai and Yellow seas.
