"The Australian coastline is 18% occupied by a very special and beneficial habitat of extraordinary trees and larger shrubs bathed regularly by flooding tides and washing waves. This practical guide describes each of these highly adapted plants." - - Back cover.
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.
A comprehensive update of this popular and practical introduction to mangrove and seagrass biology providing a concise and affordable overview.
Protection of the environment has nowadays become a major challenge and a condi tion for survival of future human generations and life on Earth in general. Yet it is still far too much of a dream or hope rather than a reality in the policy of our societies. Presently we are experiencing an unprecedented exponential growth of demography combined with a race for profit, resulting in excessive consumption particularly of en ergy, and a serious impact on the world ecosystems. Various types of pollutants and emerging new diseases not only disrupt the normal course of life, but also above this some of the atmospheric pollutants are most likely involved in the changing climate. We fear and literally shiver at the thought that the "changing climate" would ultimately disrupt the fragile thermodynamic equilibrium between the atmosphere and the oceans. Are we insensitive to these facts to the point of pushing our descendants, some genera tions ahead, into a new glacial period after a first period of warming up, at least, in northern Europe, like the one that took place 13 to 14 millennia ago? Surely the planet's nature is not prepared to be dominated by man and will go its way, whether humanity will be alive or dead.
Coral reefs are the largest landforms built by plants and animals. Their study therefore incorporates a wide range of disciplines. This encyclopedia approaches coral reefs from an earth science perspective, concentrating especially on modern reefs. Currently coral reefs are under high stress, most prominently from climate change with changes to water temperature, sea level and ocean acidification particularly damaging. Modern reefs have evolved through the massive environmental changes of the Quaternary with long periods of exposure during glacially lowered sea level periods and short periods of interglacial growth. The entries in this encyclopedia condense the large amount of work carried out since Charles Darwin first attempted to understand reef evolution. Leading authorities from many countries have contributed to the entries covering areas of geology, geography and ecology, providing comprehensive access to the most up-to-date research on the structure, form and processes operating on Quaternary coral reefs.
