I have just finished writing a textbook that is of potential interest to people doing research in the life sciences,
Anderson, D. R. 2008. Model Based Inference in the Life Sciences: A Primer on Evidence. Springer, New York, NY. This book was written for people new to the information-theoretic approaches. The book is short (184pp), paperback, and inexpensive ($39). The book is as much about science philosphy and the concept of information as it is about statistics and inference. The last chapters discuss ways of making formal inference from more than one model in an a priori set (multimodel inference). Exercises follow most chapters as does a "Remarks" section. David R.
