A Dutch-Malaysian expedition to the remote "Heart of Borneo" have turned up more than 160 species previously unknown to science — and perhaps more importantly, enough DNA samples to figure out how more than 1,400 species in one of the world's hottest hot spots for biodiversity are related.
"It has been a successful expedition," the project's leader, Menno Schilthuizen of the Naturalis Biodiversity Center, said in a news release from the center, based in the Dutch city of Leiden. Forty researchers from Naturalis and from Sabah Parks, a Malaysian conservation group, journeyed to Borneo's Mount Kinabalu last month to survey the area.
Scientists collected 3,500 DNA samples during the two-week expedition. Back in the lab, Naturalis' biologists will analyze the genetic code to generate family trees for all the collected plants, fungi and animals. A close look at the relationships among the novel species found on Kinabalu, compared with the wider spectrum of species throughout Borneo, could tell researchers whether Kinabalu's species evolved long ago or only recently.
"It's the first time that such an extensive expedition will go to Borneo with evolution as their main focus," Schilthuizen said. "We are following in the footsteps of Alfred Russel Wallace, who formulated a first version of the theory of evolution on Borneo."
Naturalis said spiders and fungi accounted for the largest numbers of new species found on Kinabalu. Other new species included true bugs, beetles, snails, stalk-eyed flies, damselflies, ferns, termites and possibly a frog.
The expedition came across an "El Dorado" for fungi, said József Geml, one of the researchers. "While the plant and animal life of this mountain has been the focus of numerous research projects, Kinabalu has remained terra incognita for scientific studies on fungi," Geml said. "It is difficult not to feel overwhelmed by this task. One of the manifestations of this diversity comes in the endless variety of shapes and colors that sometimes are truly breathtaking."
The researchers expect that the DNA studies will result in a scientific publication about evolution in the Heart of Borneo within a year. In the meantime, feast your eyes on these snapshots from the hot spot:
