Description: The extreme biological richness of Indo-Pacific fishes inspires speculation regarding the origins and maintenance of marine biodiversity such as the regular decrease in species richness from the Indo-Australian Archipelago (IAA) to the remote Insular Pacific. Comparative approaches among species can provide substantial insights into the complex physical and ecological processes that create and maintain biodiversity. 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. The proposed session will encompass a broad range of disciplines (i.e. population genetics, phylogeography, macroevolution, paleoenvironmental reconstruction, biogeography, functional ecology) with the ultimate goal of providing new insights regarding the mechanisms that shaped current biogeographical patterns and the processes required to sustain them. The overarching goal of the session is to promote exchange among different disciplines to inspire future multi-disciplinary approaches for the study of coral reef fish biodiversity thereby developing 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.
