Genetic diversity and potential function of microbial symbionts associated with newly discovered species of Osedox polychaete Worms

Article Abstract:

The genetic diversity of symbiotic bacteria associated with two newly discovered species of Osedax isolates from Monterey Bay is investigated. The members of this unusual genus of bone-eating worms have formed variable associations with symbiotic bacteria that allows for the observed differences in colonization and success in whale fall environments throughout the world's oceans.

Novel forms of structural integration between microbes and a hydrothermal vent gastropod from the Indian Ocean

Article Abstract:

Novel forms of structural integration between endo- and episymbolic microbes and an unusual new species of snail from hydrothermal vents in the Indian Ocean are described. This novel metazoan-microbial collaboration illustrates the great potential of oganismal adaptation in chemically and physically challenging deep-sea environments.

Environmental acquisition of thiotrophic endosymbionts by deep-sea mussels of the genus bathymodiolus

Article Abstract:

A hybrid population of mussels from the mid-Atlantic ridge (MAR) is exploited to test the strictly cytoplasmic maternal cotransmission (SCMC) hypothesis. The northern and southern mussel species differ diagnostically in their mitochondrial DNA sequences, and they integrate along an intermediate segment of the MAR axis.
