Book Description
Mangroves are distinctive tropical plant communities that occupy the intertidal zone between sea and land. They are of major ecological importance, have economic value as a source of food and raw materials, and serve as a buffer from flooding and climate change-induced sea level rise. Mangroves are under threat from pollution, clearance and over-exploitation, and increasing concern has driven demand for an improved understanding of mangrove species. This book provides an introduction to mangroves, including their taxonomy, habitat-specific features, reproduction and socio-economic value. Fully updated to reflect the last two decades of research, this new edition of a key text includes newly documented taxa, new understandings of vivipary and the evolution of mangrove species, and a rich set of colour illustrations. It will appeal to researchers and students across a range of disciplines, including botany, ecology and zoology.

Book Description
The first volume of Evolutionary Bio/ogy was published eleven years ago. Since that time eleven volumes and one supplement have appeared. As stated in earlier prefaces, we are continuing the focus of this series on critical reviews, commentaries, original papers, and controversies in evolu tionary biology. lt is our aim to publish papers primarily of greater length than normally published by society journals and quarterlies. We therefore invite colleagues to submit chapters that fall within the focus and standards of Evolutionary Bio/ogy. The Editors vii Contents 1.
