Competing Interests

National Geographic Conservation Trust, Columbus Zoo and Aquarium, Disney Worldwide Conservation Fund and The Rufford Foundation may be commercial funders but they just give us a grant and do not expect anything in return. Our relationship with National Geographic Conservation Trust, Columbus Zoo and Aquarium, Disney Worldwide Conservation Fund and The Rufford Foundation is purely a donor/fund recipient one and we have no competing interests. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
