The opening chapters introduce the essential molecular and genetic concepts that underpin the subject and describe key molecular tools and methods available to the ecologist. Capturing the broad scope of the field, the book goes on to explore the use of molecular tools in the context of behavioral ecology, population genetics, phylogeography, conservation, and microbial ecology. The third edition includes coverage of exciting new technological and analytical developments, such as next generation sequencing, which have revolutionized the field over the last decade. Molecular ecology is now in a position to tackle some truly ecological questions for the first time since its inception. Blending conceptual detail with the most instructive examples, is an ideal resource for those new to the subject needing to develop a strong working understanding of the field.
