I've made the report publicly available on figshare.com, a repository for
here is a direct link:
The complete report can be safely downloaded from there. Dr. Aiken, my then
supervisor at The UWI, Mona, currently has a peer reviewed paper based on
this research in press to be published by the Revista de Biologia Tropical,
but until then, this is the closest to publication I can get!
Let me know if you have any questions, I'd be glad to answer.
