I am working in a group looking to understand the role of forest elephants in structuring tropical forest communities. A part of this project would be determining how far elephants disperse seeds.
Now we can model this, but it is a punt in the dark without finding out seed passage times (how long a seed takes to get through an elephants digestive system). I am trying to think of ways of measuring this without harming the elephants (e.g. using a temperature data logger), and in such a way theat we can recover any devices we do use (elephants can go a long way in 24-48 hours).
If anyone one has any ideas, or has worked on a similar project, let me know!
