Genetic Connectivity of Pelagic Fishes (Katsuwonus pelamis and Scomberomorus commerson) across the Indo-West Pacific Alexis Jackson 1, Paul Barber 2 1. Yale University 2. Boston University, MBL
2
Species of Study Katsuwonus pelamis Scomberomorus commerson Katsuwonus pelamis
3
°° Katsuwonus pelamis Scomberomorus commerson
5
Biogeography of Indo-West Pacific
6
Regional genetic differentiation of Linckia laevigata
7
Collection Sites
8
Objectives 1. Investigate population structure of pelagic fishes in IWP 2. Investigate population dynamics of pelagic fish
9
Hypotheses 1. Fishes not affected by Pleistocene 2. Limited flow to Indian and Pacific 3. K. pelamis different from Scomberomorus
