Biogeography and biodiversity in the marine tropics: phylogenetic patterns highlight evolutionary processes driving the diversity and provinciality of coral reef fishes

Dr Peter Cowman, Australian Research Council (ARC) Centre of Excellence for Coral Reef Studies, James Cook University, Townsville, Australia

 

Combined with fossil data, time calibrated phylogenies (chronograms) can provide a window into the past, allowing the exploration of the evolutionary origins of lineages, the traits they possess, and their ancestral biogeographic affinities.

In this talk, Dr Peter Cowman will highlight how he and his collaborators have used phylogenetic trees for several families of reef-associated fishes to explore their origins and diversification on coral reefs. He will explore how reef fishes have become a major component of the Indo-Australian Archipelago (IAA) biodiversity hotspot. By integrating phylogenetic diversity metrics with ancestral biogeographic estimation of lineages, Dr Cowman will illustrate how reef fish assemblage structure and tropical provinciality have changed through time, and how they reflect both shallow and deep time connections among shallow water reef habitat.
