The islands of the South Pacific are exceptional places, as are the island of New Guinea and Australia. Together they constitute the region of Oceania, one of the most biodiverse regions in the world. In addition to the highly diverse island of New Guinea, the region includes six biodiversity hotspots (East Melanesian Islands, Forests of East Australia, New Caledonia, New Zealand, Polynesia-Micronesia and Southwest Australia) and the Coral triangle (the most diverse marine region in the world). Yet the land (terrestrial) biota in many parts of this region has received little public attention. As a result awareness of the biological uniqueness of this area is relatively low. In this blog, I hope to bring to your attention the unique biodiversity of Oceania and the natural and anthropogenic processes that have created it and are continuing to affect it. I will talk about current issues and highlight some of the ongoing interesting research in the region. This will hopefully result in greater awareness about the biodiversity of Oceania.
