Terrestrial hermit crabs are among the most widespread beach-dwelling organisms with key ecological functions but receive only very limited research attention. Sebastian Steibl demonstrates how physical parameters shape their overall distribution, presents a possible mechanism for their speciation and coexistence and shows for the first time how different human activities can have a major impact on their populations. The author points out that terrestrial hermit crabs, due to their conspicuous behavior to utilize shells, are a good model to study mechanisms of competition and coexistence in natural populations. Furthermore, they are suitable indicator organisms to assess human impact, as they respond differently depending on the type of anthropogenic disturbance. About the Author: Sebastian Steibl is a PhD student at the Institute of Animal Ecology at the University of Bayreuth, Germany. In his actual PhD research, he builds up on the presented work to investigate the architecture as well as functionality of small insular ecosystems and to analyze how different anthropogenic disturbances impact those ecosystem processes.

Two troubled turtles and one sinking friendship. Can Fish Kid save them all or will it end in turtle disaster? Fish Kid’s third epic ocean adventure is set on a small island in the Maldives, the perfect place for Fish Kid to supercharge his fish powers. His friendship with bestie, Emely, soon hits a snag during a tricky sea turtle rescue. Secretly wishing for powers of her own, Emely’s strange behaviour leaves Fish Kid wondering if their friendship and the super-sick turtle will survive. And if things weren’t bad enough, another turtle from the sanctuary goes missing. Can this super hero-in-the-making use his fishy powers to save the day?

This book covers in one volume materials scattered in hundreds of research articles, in most cases focusing on specialized aspects of coral biology. In addition to the latest developments in coral evolution and physiology, it presents chapters devoted to novel frontiers in coral reef research. These include the molecular biology of corals and their symbiotic algae, remote sensing of reef systems, ecology of coral disease spread, effects of various scenarios of global climate change, ocean acidification effects of increasing CO2 levels on coral calcification, and damaged coral reef remediation. Beyond extensive coverage of the above aspects, key issues regarding the coral organism and the reef ecosystem such as calcification, reproduction, modeling, algae, reef invertebrates, competition and fish are re-evaluated in the light of new research and emerging insights. In all chapters novel theories as well as challenges to established paradigms are introduced, evaluated and discussed. This volume is indispensible for all those involved in coral reef management and conservation.

Interest in land crabs has burgeoned as biologists have increasingly focused on the evolution of terrestriality. Before the publication of this volume in 1988, there had been no single comprehensive source of information to serve biologists interested in the diverse aspects of terrestrial decapod crustacean. Biology of the Land Crabs was the first synthesis of recent and long-established findings on brachyuran and anomuran crustaceans that have evolved varying degrees of adaptation for life on land. Chapters by leading researchers take a coordinated evolutionary and comparative approach to systematics and evolution, ecology, behaviour, reproduction, growth and molting, ion and water balance, respiration and circulation, and energetics and locomotion. Each discusses how terrestrial species have become adapted from ancestral freshwater or marine forms. With its extensive bibliography and comprehensive index, including the natural history of nearly eighty species of brachyuran and anomuran crabs, Biology of the Land Crabs will continue to be an invaluable reference for researchers and advanced students.
