Bigeye thresher shark Alopias superciliosus movements and post-release survivorship following capture on linked buoy gear Scott A. Aalbers, Michael Wang, Charles Villafana, Chugey A.Sepulveda ABSTRACT: Off the US west coast, fishery development efforts have led to the recent recommendation for authorization of deep-set buoy gear (DSBG) and linked buoy gear (LBG), two commercial gear types

Intergenerational microbial transmission in the little skate

Intergenerational microbial transmission in the little skate (Leucoraja erinacea) Katelyn Mika, Alexander S. Okamoto, Neil H. Shubin, David B. Mark Welch ABSTRACT: Microbial transmission from parent to offspring is hypothesized to be universal in vertebrates. However, evidence for this is limited as many clades remain unexamined. Chondrichthyes, as one of the earliest–branching vertebrate lineages, provide

Phylogenetic significance of clasper morphology of electric rays

Phylogenetic significance of clasper morphology of electric rays (Chondrichthyes: Batoidea: Torpediniformes) Renan A. Moreira, Marcelo R. de Carvalho ABSTRACT: Torpediniformes (electric rays) is a monophyletic group strongly supported by morphological and molecular phylogenetic studies. The claspers of electric rays, however, are poorly documented in comparation to the clasper of other batoids, especially skates, and the
