Description: The extreme biological richness of Indo-Pacific fishes inspires speculation regarding the origins and maintenance of marine biodiversity. Geographic comparisons among species, especially phylogeographic comparisons, can provide substantial insights into the complex physical and ecological processes that create and maintain alpha and beta diversity. The comparative approach brings replication among species such that general patterns can be inferred and specific hypotheses can be tested. For example, multispecies spatial comparisons can identify locations harboring elevated or unique biodiversity, can quantify the strength and quality of connectivity among sites, and can test for the effects of specific geographic attributes on gene flow. The comparative approach also facilitates testing the effects of species traits on intraspecific attributes including population structure. Such comparative investigations are enabled by biogeographic and phylogeographic characterizations for a growing number of Indo-Pacific species and data syntheses among research groups. This session strives to bring together researchers from across a variety of disciplines to develop a more comprehensive understanding the region’s biodiversity processes – a cornerstone of effective management.

Expected Audience: Our broad target audience includes interdisciplinary researchers in the areas of biogeography and phylogeography who take a multispecies and geographic approach to understanding fish biodiversity. Approaches include population genetic, genomic, comparative biology, seascape ecology, experimental, and theoretical modeling applications. We will especially seek to highlight initiatives focused on developing biodiversity knowledge to address the goal of developing more effective regional fisheries management strategies.
