Abstract Detail



Biogeography

Nge , Francis Jason [1].

Biogeography of Pomaderreae (Rhamnaceae) across Australia and New Zealand marked by older continental island vicariance and recent repeated long-distance events.

The Australasian Rhamnaceae tribe Pomaderreae contains c. 250 species across 10 genera, the majority of which are found in southern Australia, with several species found across northern, southwest Western Australia, and New Zealand. Here, we aim to: (1) assess the phylogenetic relationships, infrageneric classification and (2) biogeographic and evolutionary history of this tribe. We utilised a Next Generation hybrid capture sequencing approach to obtain 40 nuclear loci and near complete plastid genome for all species within the genus. Our phylogenetic analyses provide insights into the evolutionary history of this group. In addition, multiple dispersal events were detected from Australia to New Zealand across multiple species and clades within Pomaderris. The timing, significance, and drivers of these patterns are discussed.
