This coherent text translates the methods of statisticians into "ecological English" so that students may readily apply these methods to the real world. Ecological Methodology, Second Edition provides a balance of material on animal and plant populations. It teaches students of ecology how to design the most efficient tests in order to obtain maximum precision with minimal work. The first part of the text focuses on biological and technical issues in statistical methodology. Students learn about advances that have been made in designing better sampling devices, along with the techniques and equipment used for sampling. The second part deals with creating solid statistical design, and presents all methods that are well-known to statisticians in a language and context that students will easily understand.

About the author (1999)

Charles Krebs is Professor of Zoology at the University of British Columbia in Vancouver and has been teaching for 40 years. He received his B.S. from the University of Minnesota and earned both his M.A. and Ph.D. from the University of British Columbia. In addition to teaching ecology, he has worked extensively on the population of rodents in Northern Canada, the United States, and Australia, trying to understand the mechanisms behind population fluctuations. He has published three ecology textbooks including Ecology: The Experimental Analysis of Distribution and Abundance, Fifth Edition and Ecological Methodology, Second Edition both published by Benjamin Cummings. In his spare time, Charles can be found drinking fine wines.hors have any!) hiking and kayaking. He is married and has three cats.
