This is a completely revised, updated, and expanded version of this hugely successful book, which remains the most wide-ranging and comprehensive dictionary for the study of natural history in its broadest sense. There are over 11,000 entries, providing a working dictionary for students, teachers, researchers, and anyone having an interest within the broad arena of biodiversity studies. The extensive coverage includes classical disciplines (botany, zoology, bacteriology, mineralogy, paleontology, etc.), focusing particularly on concepts, strategies, and methodologies. New information in the book reflects major scientific developments, with special attention given to terminology relating to molecular techniques and to terminology generated by recent initiatives in the study of biological diversity and global climate change. "...this work would be useful in fields such as soil science, physical anthropology, biogeography, botany, and zoology. Fans of the first edition will love the second; those in need of a first-rate biology dictionary would do well to acquire this one." Choice "...if you're looking for a readable reference, useful for academics and non-academics alike, covering not only subtleties of language but a wide range of information relevant to the practising ecologist--you've found it!"
