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
