My chosen source of ecological information is a book called, “Are We Smart Enough to Know How Smart Animals Are?” by Dr. Frans de Waal. A book originally purchased for another course, but it has become one of my most utilized and favourite reference books. I would classify this as an academic peer-reviewed review, given that it is written by a professional in the field and the schools endorsement of the book, alongside the bibliography and citations, I feel it is safe to regard it as academic. There is no methods or results sections, this book refers to many previously done studies and uses them plus his experiences in order to create his conclusions making it a review type source.
