Marine, coastal and wetland habitats are threatened, not only through exploitation, but also by the prospect of climate change - as ocean currents change course, sea levels rise, and rainfall patterns change. Even the once-common cod is now under threat from the combined effects of over-fishing and a dramatic change-induced decrease in the plankton that cod larvae feed on. Meanwhile, coral reefs remain especially vulnerable to rapid sea-level changes exacerbated by the effects of tourism and disease. This book gathers together a wide range of papers reporting on key research into the biodiversity conservation of these critical and increasingly threatened habitats. Collectively these papers provide a snap-shot of the types of problems they are experiencing, and offer a wealth of topical examples which render this volume especially valuable to teachers of courses in marine, freshwater and wetlands ecology, biological conservation and ecological restoration.
