Book Description
"Herbivorous fish can benefit reef-building corals by controlling algae that compete with corals for space, but different species of herbivores have different and complementary impacts on benthic communities. Many herbivores are targeted in reef fish fisheries, and these fisheries can strongly impact the structure of herbivore assemblages. Therefore, managers need to know how changes in the herbivore assemblage scale-up to impact the overall health of a coral reef ecosystem. The objective of this study was to obtain quantitative estimates of grazing and browsing capacity for key turf grazing and macroalgal browsing parrotfishes on Caribbean coral reefs, and to use these metrics to quantify the combined grazing impacts of an entire assemblage of parrotfishes. Field work was carried out in the Florida Keys National Marine Sanctuary (FKNMS), where fishing on herbivorous fishes is prohibited and there are large populations of several species of parrotfishes that are rare or absent throughout much of the Caribbean"--Project summary.

Book Description
This volume investigates the effects of human activities on coral reefs, which provide important life-supporting systems to surrounding natural and human communities. It examines the self-reinforcing ecological, economic and technological mechanisms that degrade coral reef ecosystems around the world. Topics include reefs and limestones in Earth history; the interactions between corals and their symbiotic algae; diseases of coral reef organisms; the complex triangle between reef fishes, seaweeds and corals; coral disturbance and recovery in a changing world. In addition, the authors take key recent advances in DNA studies into account which provides new insights into the population biology, patterns of species distributions, recent evolution and vulnerabilities to environmental stresses. These DNA analyses also provide new understandings of the limitations of coral responses and scales of management necessary to sustain coral reefs in their present states. Coral reefs have been essential sources of food, income and resources to humans for millennia. This book details the delicate balance that exists within these ecosystems at all scales, from geologic time to cellular interactions and explores how recent global and local changes influence this relationship. It will serve as an indispensable resource for all those interested in learning how human activities have affected this vital ecosystem around the world.

Book Description
Parrotfish are found on almost every coral reef in the world. This ubiquity and uniqueness of their feeding action make them one of the most important groups of fishes within coral reef ecosystems. But why, exactly, are parrotfish so important to reefs? Can the evolution of a particular jaw morphology and feeding action really have had such a large impact on the health and functioning of the world's coral reefs? This book introduces the reader to this fascinating group of fishes (Labridae, Scarinae), from the morphological innovation of a jaw that has the power to bite through solid calcium carbonate, to the threats currently faced by parrotfish populations around the world. It contains new insights into their diet and food processing ability, and lifehistories, and concludes with an overview of emerging and future research directions.

Book Description
"This document provides practical advice to field practitioners based on an example from the Asia Pacific Region. Key functional groups of herbivores are identified, species are assigned to each functional group, and methods are provided for monitoring their abundance, biomass and size structure ... This document represents the first attempt to develop a monitoring program that is specifically designed to monitor key functional groups of herbivorous reef fishes as indicators of coral reef resilience. Even though it is based on the best available information, it is important to remember that the science underpinning these methods is still new and developing. Further research is now required to address knowledge gaps and refine monitoring methods"--Executive summary.

Book Description
Coral Reef Fishes is the successor of The Ecology of Fishes on Coral Reefs. This new edition includes provocative reviews covering the major areas of reef fish ecology. Concerns about the future health of coral reefs, and recognition that reefs and their fishes are economically important components of the coastal oceans of many tropical nations, have led to enormous growth in research directed at reef fishes. This book is much more than a simple revision of the earlier volume; it is a companion that supports and extends the earlier work. The included syntheses provides readers with the current highlights in this exciting science. * An up-to-date review of key research areas in reef fish ecology, with a bibliography including hundreds of citations, most from the last decade * Authoritative and provocative chapters written to suggest future research priorities * Includes discussions of regulation of fish populations, dispersal or site fidelity of larval reef fishes, sensory and motor capabilities of reef fish larvae, and complexities of management of reef species and communities

Book Description
Parrotfishes (subfamily Scarinae, family Labridae), named for their brightly colored bodies and beaklike jaw, are a unique group of marine fishes that have captured the attention of researchers, conservationists and the general public worldwide. This book brings together the world's leading authorities on the evolution, biology, ecology, fisheries and conservation of parrotfishes. In doing so, it provides a comprehensive summary of the research conducted on this unique group of fishes and highlights emerging topics and future direction.
