Abstract: This project represents a survey of the genetic diversity of massive corals in the genus Porites in Guam and the Commonwealth of the Northern Mariana Islands (CNMI). DNA barcoding conducted across three habitats and seven islands revealed high cryptic diversity with some genetic clades hosting specific habitat preferences. In-depth genetic analysis of two clades within this complex revealed striking differences in their patterns of population connectivity, structure, and relative admixture between populations. These findings reveal stark differences in genetic trends that are occurring at relatively fine evolutionary scales. Results presented here underscore the need for clade-level considerations for management, conservation, and broader understanding of Mariana reef biota.
