Galapagos Tortoises

My friend Stephen Blake has collected movement data on Galapagos Tortoises  for two years.

The data is available at

We would like to understand more about the tortoises's movement, for example

what makes them migrate, how are they influenced by climate changes,

why smaller tortoises don't migrate, how they choose routes, etc.

If you are interested in working on these problems, let me know.
