Join us for a Bio at Noon seminar from Dr. Corinna Breusing (URI).
Title: Evolutionary genetics and physiology of mollusk-bacteria symbioses from deep-sea chemosynthetic environments.
Abstract: “Animal-microbe symbioses are increasingly recognized as ubiquitous biological phenomena that are crucial for many ecological and evolutionary processes. In the deep sea, intriguing mutualistic symbioses exist between invertebrate animals and chemosynthetic microbes that form the basis of many vent and seep ecosystems worldwide. While both mineral and genetic resources from these unique ecosystems gain increasing interest in human society, plans for the sustainable management of vent and seep biodiversity are still in their infancies, given that the genetic structure, connectivity and ecology of associated animal and microbial populations is poorly understood. In this seminar, I will present some aspects of my work on the evolution, conservation and physiology of symbiotic mollusk species from deep-sea chemosynthetic environments. Specifically, my talk will address 1) gene flow and genetic subdivision in the ecologically important deep-sea mussel species (Bathymodiolus spp.) from mid-Atlantic vents, 2) unusual symbiont transmission pathways in vesicomyid clams and 3) planned studies on symbiont-mediated niche partitioning in deep-sea vent snails of the genus Alviniconcha.”
