"""In 1970, the book The Wolf: Ecology and Behavior of an Endangered Species was published, written by David Mech. It was a success. The book helped to popularize the alpha concept, because many people referred to Mech's work.

Mech has written on his website that he repeatedly asked the publisher to stop printing the book because much of the information is outdated — including the concept behind the alpha wolf. Nevertheless, the book is still being sold."""
