A well done, but brief, piece of science reporting. Despite the aforementioned brevity, the write-up is chock-full of information. As a Fellow of the Royal Geographical Society, I found myself in my element reading this article. An immensely informative and intellectually engaging read. Kudos to the Author for his pleasant writing style. Regrettably, it does not seem that the study referenced is available in full but merely the Abstract. The Abstract is though worth reading and adds more context. A decidedly worthwhile read on a topic, which until recently seemingly, was not in the forefront of scientific research.
