Shedding light: a phylotranscriptomic perspective illuminates the origin of photosymbiosis in marine bivalves

Jingchun Li, Sarah Lemer, Lisa Kirkendale, Rudiger Bieler, Colleen Cavanaugh & Gonzalo Giribet
Background: Photosymbiotic associations between metazoan hosts and photosynthetic dinoflagellates are crucial to the trophic and structural integrity of many marine ecosystems, including coral reefs. Although extensive efforts have been devoted to study the short-term ecological interactions between coral hosts and their symbionts, long-term evolutionary dynamics of photosymbiosis in many marine animals are not well understood. Within Bivalvia, the second largest class of mollusks, obligate photosymbiosis is found in two marine lineages: the giant clams (subfamily...

Going with the flow: corals in high-flow environments can beat the heat

James Fifer, Bastian Bentlage, Sarah Lemer, Atsushi Fujimura, Michael Sweet & Laurie Raymundo
Coral reefs are experiencing unprecedented declines in health on a global scale leading to severe reductions in coral cover. One major cause of this decline is increasing sea surface temperature. However, conspecific colonies separated by even small spatial distances appear to show varying responses to this global stressor. One factor contributing to differential responses to heat stress is variability in the coral’s micro-environment, such as the amount of water flow a coral experiences. High flow...

Evolutionary biogeography of the reef-building coral genus Galaxea across the Indo-Pacific ocean

Stony corals (Scleractinia) form the basis for some of the most diverse ecosytems on Earth, but we have much to learn about their evolutionary history and systematic relationships. In order to improve our understanding of species in corals we here investigated phylogenetic relationships between morphologically defined species and genetic lineages in the genus Galaxea (Euphyllidae) using a combined phylogenomic and phylogeographic ap- proach. Previous studies revealed the nominal species G. fascicularis included three genetically well-differ-...
