I don't know how many of you have ever read this article but it was published in 2003 by the Biological Journal of the Linnean Society and it has some very interesting findings. For those who have never read a scientific paper or may not have a lot of experience I suggest reading the Abstract and the results first to get the basic idea of the study. Being a Wildlife Biologist I am a google scholar nut. :D
I hope you enjoy!
