Ste. Marguerite River until they reached the Labrador Plateau, which they were required to trek across to access the Moisie River. Eventually they reached the Hamilton River and finally Ungava Bay and their destination, Fort Chimo. Although the trip was not without its trials, especially when they were unsure of the correct direction of their destination, it was a success overall for amassing specimens. In total 1,862 specimens were collected, which represented 141 species of birds and 30 species of mammals. Murie’s time in Canada provided him with skills needed for a lifetime working in wildlife biology. Because of the pristine and relatively untouched conditions of the arctic due to the lack of humans, Murie was able to establish a more holistic understanding of humans’ impact on an environment, which he would develop more in subsequent trips around North America. Alaska In 1920, following his work in Canada, Murie accepted a position working for the U.S. Biological Survey in Alaska, studying the caribou in Alaska to locate the largest caribou populations, with the intention of crossbreeding them with reindeer. Murie was also expected to collect specimens of various animals, and act as a Fur Warden by enforcing laws that protected animals against illegal fur trade practices. Murie was also encouraged to ensure large caribou populations in the region. To do so, one practice employed by the U.S. Biological Survey during this time was predator poisoning, which reduced predator populations in order to increase prey species. However, the more Murie studied caribou populations, the more he opposed this idea.] Although Murie at first was not extremely vocal in his opposition, he began to express his views. He remarked, “I have a theory that a certain amount of preying on caribou by wolves is beneficial to the herd, that the best animal[s] survive and the vigor of the herd is maintained. Man's killing does not work in this natural way, as the best animals are shot and inferior animals left to breed. I think that good breeding’s as important in game animals as it is in domestic stock. With our game, however we have been accustomed to reverse the process killing off the finest animals and removing the natural enemies which tend to keep down the unfit.” Murie saw that hunting by humans was counter to trends produced by nature, and counteracted Darwin’s survival of the fittest. He believed the true cause
