Molecular analysis of parapoxvirus from a spotted seal Phoca largha in Japan

Preliminary Report - Biology of the Spotted Seal (Phoca largha) in Alaska from 1962 to 2008

Cranial features of the spotted seal, Phoca largha, in the Nemuro Strait, considering age effects.

Cranial features (development, individual variation, and sexual dimorphism) were examined from the 23 metrical characters and 2 nonmetrical characters (the degree of closure of the 9 cranial sutures and the presence of sagittal crest) in the two spotted seal specimen groups at the Nemuro Strait, Hokkaido. One specimen group was incidentally taken in the salmon trap nets between 1982 and 1983 (n...

Sequence variation and gene duplication at the MHC DRB loci of the spotted seal Phoca largha.

The major histocompatibility complex (MHC) is one of the most important genetic systems associated with resistance to infectious diseases in vertebrates. The spotted seal (Phoca largha) is one of the most endangered species in China. In this study, we present the first step in the molecular characterization of a DRB-like locus in the spotted seal by analyzing the nucleotide sequence of the poly...

Molecular Analysis of Parapoxvirus Detected in Eight Calves in Japan

Molecular analysis of parapoxvirus envelope genes was performed. Parapoxvirus DNA was detected in eight calves from eight farms in Iwate Prefecture, Japan, between April and September 2010. Seven of the detected viruses were identified as bovine papular stomatitis virus (BPSV) by sequencing, because their nucleotide identity was more than 96.8% similar compared with BPSV strain V660. Among them...

Amphibious hearing in spotted seals (Phoca largha): underwater audiograms, aerial audiograms and critical ratio measurements.

Spotted seals (Phoca largha) inhabit Arctic regions that are facing both rapid climate change and increasing industrialization. While little is known about their sensory capabilities, available knowledge suggests that spotted seals and other ice seals use sound to obtain information from the surrounding environment. To quantitatively assess their auditory capabilities, the hearing of two young ...
