Dr. Charles Krebs

Charles J. Krebs is an international authority on the population dynamics of small mammals, which, at successive stages of his career, he has studied in the Eastern Arctic, England, California, Indiana, British Columbia, and the Yukon. Although small mammals are his specialty, Dr Krebs is well acquainted with the general population literature on plants and animals, and has written an outstandingly good text-book, now in its second edition. The principal thrust of the book is that ecological problems are unlikely to be solved until descriptions are followed up by experiments. Besides being a productive research worker, Dr Krebs is an excellent teacher.
