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.

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.

Reefs provide a wealth of opportunity for learning about biological and ecosystem processes, and reef biology courses are among the most popular in marine biology and zoology departments the world over. Walter M. Goldberg has taught one such course for years, and he marshals that experience in the pages of The Biology of Reefs and Reef Organisms. Goldberg examines the nature not only of coral reefs—the best known among types of reefs—but also of sponge reefs, worm reefs, and oyster reefs, explaining the factors that influence their growth, distribution, and structure. A central focus of the book is reef construction, and Goldberg details the plants and animals that form the scaffold of the reef system and allow for the attachment and growth of other organisms, including those that function as bafflers, binders, and cementing agents. He also tours readers through reef ecology, paleontology, and biogeography, all of which serve as background for the problems reefs face today and the challenge of their conservation. Visually impressive, profusely illustrated, and easy to read, The Biology of Reefs and Reef Organisms offers a fascinating introduction to reef science and will appeal to students and instructors of marine biology, comparative zoology, and oceanography.

Coral reefs represent the most spectacular and diverse marine ecosystem on the planet as well as a critical source of income for millions of people. However, the combined effects of human activity have led to a rapid decline in the health of reefs worldwide, with many now facing complete destruction. Their world-wide deterioration and over-exploitation has continued and even accelerated in many areas since the publication of the first edition in 2009. At the same time, there has been a near doubling in the number of scientific papers that have been written in this short time about coral reef biology and the ability to acclimate to ocean warming and acidification. This new edition has been thoroughly revised and updated, incorporating the significant increase in knowledge gained over the last decade whilst retaining the book's focus as a concise and affordable overview of the field. The Biology of Coral Reefs provides an integrated overview of the function, physiology, ecology, and behaviour of coral reef organisms. Each chapter is enriched with a selection of 'boxes' on specific aspects written by internationally recognised experts. As with other books in the Biology of Habitats Series, the emphasis in this book is on the organisms that dominate this marine environment although pollution, conservation, climate change, and experimental aspects are also included. Indeed, particular emphasis is placed on conservation and management due to the habitat's critically endangered status. A global range of examples is employed which gives the book international relevance.

Parrotfish is startled by a strong current sweeping through the reef, when suddenly Eagle Ray appears overhead to warn Parrotfish and his neighbors that a storm is coming and to take cover. Once the storm finally passes, Parrotfish is surprised at how much their reef has changed. It's up to him and his neighbors to restore their coral reef to its former state, and to help a neighboring reef that is struggling to recover. The involvement of an unlikely helper causes an initial stir, but to everyone's surprise ends up being a hero in the effort to save the neighboring reef in trouble.An ecological story about coral reef resilience and recovery, underlining the importance of herbivores and apex predators in maintaining a coral reef ecosystem's delicate balance and ability to recover after a large-scale disturbance.

Angela Katz-McNair has never felt quite right as a girl, but it’s a shock to everyone when she cuts her hair short, buys some men’s clothes, and announces she’d like to be called by a new name, Grady. Grady is happy about his decision to finally be true to himself, despite the practical complications, like which gym locker room to use. And though he didn’t expect his family and friends to be happy about his decision, he also didn’t expect kids at school to be downright nasty about it. But as the victim of some cruel jokes, Grady also finds unexpected allies in this thought-provoking novel that explores struggles any reader can relate to.
