Comprehensive guide to world's species - 83 angelfishes and 121 butterflyfishes.
Butterflyfishes (family Chaetodontidae) are a highly conspicuous component of fish fauna on coral reefs throughout the world. In light of their strong dependence on coral, they are often regarded as the epitome of coral reef fishes. This volume examines the ecology and conservation of coral reef butterflyfishes. It provides important insights on their evolution and key events and adaptations that have led to their proliferation within coral reef ecosystems. Key to the longevity of butterflyfishes is the evolution of coral-feeding—a central focus of the ecological chapters in this volume. The book also highlights key threats and challenges related to the conservation of butterflyfishes and ends with an overview of current and future research directions.
A fragile outsider living in London, Joy struggles to pull the threads of her life back together after her mother's sudden death. As family secrets come to light, she unearths the ties between her mother, grandfather, the wife of the king, a fearsome warrior, and a brass head's pivotal connection to them all.
Butterflyfishes of the family Chaetodontidae are conspicuous members of almost all tropical reefs. These colorful fishes have attracted a great deal of attention from both the scientific community and especially the aquarium fish industry. At first one is tempted to say that butterflyfishes are abundant worldwide, but the evidence does not support this statement. The biomass of chaetodontids on reefs may range from 0.02-0.80%, and in terms of numbers they comprise only 0.04-0.61 % of the individuals on the reef. Yet in spite of these relatively small numbers they have been extensively studied. A quick census shows some 170 articles on or about butterfly fishes, with 78% of them being published since the 1970's. Along with the cichlids and damselfishes they might be one of the most studied and well published family of tropical fishes. Why then have chaetodontids attracted so much attention? The butterflyfishes are mostly shallow water inhabitants that are approachable and easily recognizable, making their study very feasible. Their bright coloration has provoked many hypotheses but has posed more questions about coloration than it has provided answers. And despite their apparent overall morphological similarity, their highly structured and varied social systems have made them an ideal model for such studies. The reasons for choosing these organisms are indeed as diverse as the studies themselves.
Ages 9 to 12 years. A must-have for any home or school library, this fascinating book highlights 30 of the most fascinating creatures in the sea. The beautiful full-colour photographs and interesting descriptions highlighting the design features of each creature make this book a must read.
The need for a volume dealing with the concept of indicator organisms became evident during a symposium on the subject, organized by the present editors for the Southern California Academy of Sciences. Ques tions were posed about the appropriate uses of indicator organisms and the "rules" governing the application of the indicator concept to particular problems. For example, how does one distinguish true indicators from biological anomalies? What kinds of organisms can appropriately be associated with conditions and events at various scales in time and space? To what extent does one species represent other species in the same environmental setting? Can the indicator concept be applied to the context of modern sampling and analytical technology? How can anthropogenic perturbations be distinguished from natural phenomena? How can unlike matrices from differing data bases with differing scales best be matched? Such questions are especially pertinent in today's research environment. The use of indicator organisms, while certainly not new, is the corner stone for much scientific research. In the past two decades, indicator organisms have played increasingly important roles in the development and implementation of public policy. In particular, indicator organisms are being used to describe local environments and natural or anthropogenic perturbations to them, although there are pitfalls and problems associated with those usages. A growing number of nonbiologists, including physical oceanographers, find indicator organisms helpful, and sometimes essential, to their re search.
