Oil palm development had a huge negative impact on biodiversity in SE Asia and some of its iconic species, like the orangutan. The SGA has written a position statement on this issue for Africa where bonobos, chimpanzees, and gorillas occur. Read more about this and download the statement here.
The ConservationDrones that Lian Pin and I have been flying in Sumatra have been taking a large number of photos of the forest in our search for orang-utan nests. Manually checking photos to find nests is a time-consuming task. By collaborating with a team from the ETH in Zurich we are now able to detect nests with the aid of object recognition. Check the current paper for more details.
A large collaboration of researchers led by Marc Ancrenaz published a paper on orang-utan terrestriality. It is published in Nature’s open access journal: Scientific Reports: http://www.nature.com/srep/2014/140213/srep04024/full/srep04024.html
