Project Title: AKCSI Project 6. Genetic Connectivity among Regional Populations of red tree corals (Primnoa pacifica) in the North Pacific Ocean
Project Summary

This study will build on an ongoing study using microsatellite DNA markers to generate data on the spatial scale and pattern of genetic connectivity across a large portion of the range of P. pacifica in the North Pacific Ocean.

Anticipated Management Application(s)

Knowledge of the degree to which populations are connected through larval dispersal is imperative to effective management, yet little is known about larval dispersal capability or population connectivity in Primnoa pacifica, the dominant structure forming coral on the outer continental shelf and upper slope between the Alaska Peninsula and the Olympic Coast Marine Sanctuary (OCMS) off the Washington Coast. This study will build on an ongoing study using microsatellite DNA markers to generate data on the spatial scale and pattern of genetic connectivity across a large portion of the range of P. pacifica in the North Pacific Ocean. These data will provide important insights regarding the most appropriate tools available to resource managers to protect sensitive coral habitats and the ecosystem services they provide.

Project Title: AKCSI Project 6. Genetic Connectivity among Regional Populations of red tree corals (Primnoa pacifica) in the North Pacific Ocean
Methods/Approach

As part of ongoing studies on shallow-water populations of Primnoa pacifica in the glacial fjords of Southeast Alaska we have done much of the preliminary work developing microsatellite DNA markers for that population. This project would expand that work to six other populations of Ppacifica in the North Pacific Ocean–four populations on the continental slope in the Gulf of Alaska, one on Bowie Seamount off British Columbia (Canada), and one in the Olympic Coast Marine Sanctuary off Washington State. Samples from 50 individual colonies will be collected with an ROV (or submersible) as a piggy-back project to Project 1. Collaborating scientists from DFO-Canada and NOAA-OCMS would be asked to support the collection of genetic samples contributed to this project.
