Book Description
Ten synapomorphies are described that support the proposed sister group relationship of the Eocene Kushlukiidae and the Eocene to Recent Luvaridae as the superfamilial clade Luvaroidea at the node between the siganid and zanclid+acanthurid clades of acanthuroid fishes. The Kushlukiidae previously have been known only on the basis of Kushlukia permira Danilchenko from the Eocene of Turkmenistan, but another species of that age is shown to have been present in India; the latter is not given a new specific name because the two specimens of it are only fragments. In addition to the well known Recent species Luvarus imperialis, three fossil species have been referred to the Luvaridae: Proluvarus necopinatus Danilchenko from the Eocene of Turkmenistan is here recognied as a valid species of Luvarus, with Proluvarus becoming a junior synonym of Luvarus; Eoluvarus bondei Sahni and Choudhary from the Eocene of India is shown to be not a luvarid but, rather, a member of the fossil perciform family Exelliidae, the affinities of which family are poorly understood; Luvarus praeimperialis Arambourg from the Oligocene of Iran is shown to be not a luvarid but, rather, a representative of the new genus Aluvarus of such uncertain affinity that we simply place it incertae sedis among the percomorphs. Among the materials used by Danilchenko in the description of Proluvarus necopinatus only the holotype and the five other largest specimens (about 326-495 mm SL) represent that species. All of the other specimens are smaller than about 215 mm SL and represent two new species of a new genus of luvarid, Avitoluvarus dianae and A. mariannae. Numerous derived features are used to define both the Kushlukiidae and Luvaridae. Within the Luvaridae, the preponderance of derived features is found in Luvarus, whereas Avitoluvarus has only two unequivocal synapomorphies. The Luvaroidea, therefore, are represented by the Eocene Kushlukiidae with one genus and two species (Kushlukia permira and K. sp.) and the Luvaridae with one Eocene genus with two species (Avitoluvarus dianae and A. mariannae) and one genus, Luvarus, with one Eocene species, L. necopinatus, and one Recent species, L. imperialis.

Book Description
Reef fish spawning aggregations, ranging from small groups to many tens of thousands of individuals, are spectacular but poorly known natural phenomena whereby fish assemble at specific times and locations to spawn. For some species these large groups may be the only form of reproduction, the high fish numbers briefly giving a false impression of stability and abundance—an ‘illusion of plenty’. They are often a focus for intensive seasonal fishing because of their predictability and because many important commercial fishes form them. Highly vulnerable to overexploitation, many aggregations and their associated fisheries, have disappeared or are in decline. Few are effectively managed or incorporated into protected areas. Aggregations are not well understood by fishery scientists, managers and conservationists and their significance little appreciated by fishers or the wider public. To ensure their persistence to replenish important fisheries in coral ecosystems, maintain their ecosystem function and continue to delight divers, a significant change in perspective is needed to foster protection and management. This book provides comprehensive and practical coverage of the biology, study and management of reef fish aggregations, exploring their how, when, where, and why. It explores ways to better protect, study, manage and conserve them, while identifying key data gaps and questions. The text is extensively illustrated with many unique, never before published, photographs and graphics. Case studies on over 20 interesting and important fishes are included, outlining their biology and fisheries and highlighting major concerns and challenges.

Book Description
The second volume in the Fauna Malesiana book series gives an extensive overview of the larval development of 124 families of fishes, many of them of importance for both fishery and from ecological perspectives. The families that are described originate from the center of global marine biodiversity: the tropical Indo-Pacific Oceans, a region rich in coral reefs, as well as mangrove, estuarine, and coastal shelf habitats. The identification guide not only documents the ontogeny of these fishes but also provides the means to identify these extraordinarily diverse larvae to the level of family. The book offers a wealth of instructive and detailed figures and illustrations (219 plates, each consisting of approximately 4 figures) for enabling the identification of these families and their larval specialization.

Book Description
Analysis of Genetic Variation in Animals includes chapters revealing the magnitude of genetic variation existing in animal populations. The genetic diversity between and within populations displayed by molecular markers receive extensive interest due to the usefulness of this information in breeding and conservation programs. In this concept molecular markers give valuable information. The increasing availability of PCR-based molecular markers allows the detailed analyses and evaluation of genetic diversity in animals and also, the detection of genes influencing economically important traits. The purpose of the book is to provide a glimpse into the dynamic process of genetic variation in animals by presenting the thoughts of scientists who are engaged in the generation of new idea and techniques employed for the assessment of genetic diversity, often from very different perspectives. The book should prove useful to students, researchers, and experts in the area of conservation biology, genetic diversity, and molecular biology.

Book Description
Research on the large array of tropical estuarine fishes has increased markedly in recent years and hence scientific knowledge about most aspects of these important fishes' biology and ecology is now catching up with that of their temperate equivalents. This landmark book draws together a vast wealth of information on tropical estuarine fishes and provides a vital reference point for all aspects of their study. The book's comprehensive contents include thorough coverage of the types and distribution of these fishes, their diversity and the environmental conditions and communities in which they live. Full details of their biology and ecology are an integral part of this book, as are details of these fishes' dependence on estuaries, man's interaction with the estuarine fish community and the conservation of estuarine species and the often threatened habitats upon which they depend. The author, Stephen Blaber, has a vast wealth of experience in the subject areas covered by this book and has produced a stimulating and extremely valuable volume that will be of huge importance for all those concerned with these fishes. He is based at CSIRO Marine Research, Cleveland, Queensland, Australia. Readership should include: fish biologists; fisheries scientists; aquatic scientists including those concerned with brackish, marine and freshwater environments; ecologists; environmental scientists and population biologists. Students studying for qualifications in fish biology and fisheries, particularly where there is a tropical element to their course will find this book of great value as a reference. Copies of the book should be available on the shelves of all libraries in research establishments and universities where biological sciences, fish biology, fisheries science or aquatic sciences are studied and taught.

Book Description
Ever-increasing interest in oceanography and marine biology and their relevance to global environmental issues creates a demand for authoritative reviews summarising the results of recent research. Oceanography and Marine Biology: An Annual Review has catered to this demand since its founding by the late Harold Barnes fifty years ago. Its objective
