An overarching issue, which this book addresses, is whether global climate change is a dominant driver of change in the structure and function of all natural water-based ecosystems, or whether direct human population growth and accelerated consumption are playing an equal or greater role. This book divides the whole aquatic realm into 21 ecosystems, from those on land (both saline and fresh water) to those of the open and deep oceans. It draws on the understanding of leading ecologists to summarize the state and likely condition by the year 2025 of each of the ecosystems. Written for academic researchers and environmental professionals, the aim is to put the climate change debate into a broader context as a basis for conservation science and planning.Gives detailed separate treatments of 21 ecosystems based on well-worked case studies.Unique review of how ecosystems are likely to change over the next 20 years spanning marine, freshwater and terrestrial-saline environments.Polunin puts the climate change debate into a broader context, as a basis for conservation science and decision making.
