Seasonal Dynamics of <i>Bathyarchaeota</i>-Dominated Benthic Archaeal Communities Associated with Seagrass (<i>Zostera japonica</i>) Meadows

Little is known about the seasonal dynamic of archaeal communities and their potential ecological functions in temperate seagrass ecosystems. In this study, seasonal changes in diversity, community structure, and potential metabolic functions of benthic archaea in surface sediments of two seagrass m...
