Sunda-Sahul floristic exchange and pathways into the Southwest Pacific: New insights from wet tropical forest trees
<p><strong>Aim</strong> Recent investigations on the floristic exchange between Southeast Asia and Australia have shown a clear dispersal directionality bias (West to East) of wet-adapted plant taxa. However, dispersal routes and directions of wet forest taxa into the South Pacific remain insufficiently known. We here aimed to establish the most likely routes and directions of plant dispersal into the Southwest Pacific islands.</p> <p><strong>Location</strong> Southeast Asia, East Asia, Australia, Southwest Pacific.</p> <p><strong>Taxon</strong> <em>Dysoxylum</em> s.l. (Meliaceae). This includes <em>Dysoxylum</em> s.s., <em>Didymocheton</em>, <em>Epicharis</em>, <em>Goniocheton</em>, <em>Pseudocarapa</em> and <em>Prasoxylon</em>.</p> <p><strong>Method</strong> We sampled 75% of the species diversity in <em>Dysoxylum</em> s.l., covering the entire distribution range, all genera and major lineages. Phylogenetic relationships of 149 accessions were reconstructed using Bayesian Evolutionary Analysis and two internal constraints. The dispersal–extinction–cladogenesis variant, founder-event speciation (DEC+J), was used for reconstructing the biogeographic history, and 100 BSMs were simulated.</p> <p><strong>Results</strong> <em>Dysoxylum</em> s.l. originated and firstly diversified in the western part of its current distribution range (incl. Indochina) during the Miocene to Pliocene, followed by an overall eastern range expansion towards Malesia, Australia and the Southwest Pacific in the Pliocene.</p> <p><strong>Main</strong> <strong>conclusions</strong> The south-eastward expansion of lineages into Wallacea and Australia is in temporal agreement with the convergence of the Asian and Australian tectonic plates since the Miocene. Long-distance dispersal is the main mechanism that led to the current distribution. Two dispersal pathways into the Southwest Pacific are identified, (1) through New Guinea and the Solomon Islands to Fiji, and (2) from New Zealand to Fiji. For both routes, Fiji was an important secondary source area for dispersal into the Southwest Pacific.</p>
