We wrote this book to share with other ecologists what we have learned about the structure and
use of theory and its relationship to the myriad activities that constitute modern science. Our
own quest was motivated by the sometimes unclear way in which the term “theory” is used in
both scientifi c publications and informal discussions. We needed to fi nd out what theory was

about what constitutes proper scientifi c practice.
“Cohen has produced a broad, engaging, and admirably clear discussion of intangible assets and their valuation.

Systematics may be deﬁned as the study of the kinds and diversity of organisms and the relationships among them. Taxonomy, the theory and practice of identifying, describing, naming, and classifying organisms, is an integral part of systematics.
