A Guide to Southern Temperate Seagrasses describes the exceptionally diverse seagrasses in the temperate parts of the southern hemisphere. This book introduces readers to the evolution, biology and ecology of the southern temperate seagrasses and presents a visual key to allow species identification using easily recognisable features. Detailed information is presented summarising the distinctive features of each species or 'complex', with brief notes about their taxonomy, reproduction and ecology.With information provided in a highly concise format, this book allows readers to rapidly identify a particular seagrass, as well as other species that it may easily be confused with, confirm that the species occurs in a certain area, and access general information on the biology and ecology of the species. It is a valuable resource for students, researchers, environmental consultants and both government and non-government agencies.
