Recent advances in fish cytogenetics have enhanced the interest in chromosome analysis in both fundamental (systematics and comparative genomics among fishes and other vertebrate groups) and applied (aquaculture, conservation and response to pollutants, whole genome sequencing of model fish species) research. Although the genomic material, the chromosomes, is basically the same in the various organisms, experience has clearly shown that fish chromosomes have to be handled with specific protocols. In laboratories around the world, traditional cytogenetic techniques and molecular cytogenetics have seen a vast improvement but the technical details and protocols are often not published in scientific journals because of constraints in format and size and therefore they are not accessible to the whole scientific community. These shortcomings are very well known to fish cytogeneticists and the idea to prepare a specific manual was first discussed during the first "Workshop of Fish Cytogenetics" held in Concarneau (France), in 1992. Resulting from the above workshop, a draft compilation of the techniques and protocols in fish cytogenetics available at that time had been produced and distributed privately, but never published. There does not exist, at present, any published handbook or manual specifically dealing with fish cytogenetics. This book fills this void by bringing together and updating the main techniques so that the traditional methods can be standardized. Moreover, this book includes novel developments or improvements; some of the protocols provided here are practically unknown to the scientific community and even now unpublished.

In recent years, progress in fish biology has advanced at an unprecedented rate and has led to many breakthroughs in the field. This book provides a wealth of information on the strategies that fish adopt with respect to waters with markedly different physical and chemical characteristics. It shows how their physiology, behaviour and lifestyles are adapted to exploit particular niches and gives comprehensive insight into fish life under extreme conditions. The readers are introduced to the ways in which fish exemplify many phenomena of general biological interest - the existence of competitors, chaos, and predator-prey interaction. Fish pathology as well as the components of the immune system are addressed. In this book, original and at times controversial views are presented, areas which have so far received inadequate attention are highlighted and avenues for further research are suggested.

Whether glamorised or stigmatised, teenage parenthood is all too often used to stand for a host of social problems, and empirical research results ignored. Identifying core controversies surrounding teen pregnancy and parenting, this book resolves misperceptions using findings from large-scale, longitudinal, and qualitative research studies from the US and other Western countries. Summarising the evidence and integrating it with a systems perspective, the authors explore ten prevalent myths about teenage parents, including: Teen pregnancy is associated with other behavior problems. Children of teen parents will experience cognitive delay, adjustment problems, and will themselves become teen parents. Better outcomes are achieved when teen mothers live with their own mothers. Teen pregnancy costs tax payers lots of money. Abstinence education is the best way to prevent teen pregnancy. Teen Pregnancy and Parenting ends by highlighting the prevention and intervention implications for families, practitioners, and policymakers. It will be of interest to academics and advanced students from a range of disciplines and professions including psychology, public policy, nursing, social work and sociology.

Sturgeons are considered “living fossils”, sharing many morphological and biological features with ancestral fish. Furthermore, sturgeons are of the utmost interest from an economic perspective, not only for the caviar but for the flesh. However, the wild populations of the majority of the species are at serious risk of extinction all over the world. So, it is urgent to develop strategies for both farming culture and conservation and recovery in natural habitats. This book provides a comprehensive view of the biology and sustainable development of sturgeons putting emphasis on the Southern Europe autochthonous species such as Acipenser nacarii and Acipenser sturio that share geographical distribution. Other relevant species (such as Huso huso, A. oxyrhinchus, A. ruthenus, A. stellatus) and areas (Germany, Russia, North America) are also considered. The contents are organised in three sections: Taxonomy and Biogeography (including the morphological and genetic analyses that clarify the taxonomy and phylogeny of sturgeons, focused on those from Southern Europe), Biology and Aquaculture (where several aspects of the developmental biology, feeding, and reproduction are considered in relation to the improvement of sturgeon farming), and Recovery and Conservation (that collates and analyses different recovery research actions, the ecology of the rivers for restoration as well as the problems related to the trade of caviar).

The unprecedented level of diversity recorded among the clones of self-fertilizing gynogenetic unisexuals and self-fertilizing simultaneous hermaphrodites challenges current ideas on the predominant role of recombination in promoting evolution of biological diversity. Though limited to a few species, the existence of self-fertilizing and cyclical sex changing hermaphrodites remians a puzzle to many geneticists and endocrinologists. Within a few days after the removal of a harem master or mistress, a successor changes sex and takes over the harem; the causes for the sex changing mechanism pose many challenges to socio-ecologists and behaviour specialists.This book is a synthesis of relevant and recent information on sexuality of fishes and points towards new directions of desired research.

A comprehensive study of sex differentiation gonochoric and hermaphroditic fishes, this book examines sex chromosomes and sex determining genes, emphasizing the need to search for more than one sex-determining gene residing on different chromosomes. It traces the origin of hermaphrodites from secondary gonochores and explains the conservation of homologous sex differentiation and steroid receptor genes among gonochores and hermaphrodites. The author identifies the optimal broodstock size and the appropriate candidate species for bait. He shows that the analysis of steriles and mutants has demonstrated the value of fishes as a system for genetic dissection of human development and diseases.

This is the second monograph by the author on biological materials of marine origin. The initial book is dedicated to the biological materials of marine invertebrates. This work is a source of modern knowledge on biomineralization, biomimetics and materials science with respect to marine vertebrates. For the first time in scientific literature the author gives the most coherent analysis of the nature, origin and evolution of biocomposites and biopolymers isolated from and observed in the broad variety of marine vertebrate organisms (fish, reptilian, birds and mammals) and within their unique hierarchically organized structural formations. There is a wealth of new and newly synthesized information, including dozens of previously unpublished images of unique marine creatures including extinct, extant and living taxa and their biocomposite-based structures from nano- to micro – and macroscale. This monograph reviews the most relevant advances in the marine biological materials research field, pointing out several approaches being introduced and explored by distinct modern laboratories.

This book provides a comprehensive overview of topics describing the earliest steps of fertilization, from egg activation and fertilization to the activation of the zygotic genome, in various studied vertebrate model systems. The contribution of maternal and paternal factors and their role in the early embryo as parental DNA becomes modified and embryonic genes become activated is fundamental to the initiation of embryogenesis in all animal systems. It can be argued that this is a unique developmental period, when information from the parents is compressed to direct the development of the body plan of the entire organism, a process of astounding simplicity, elegance and beauty. In addition to their fundamental scientific interest, many frontiers of biomedicine, such as reproductive biology, stem cells and reprogramming, and the understanding of intergenerational diseases, depend on advances in our knowledge of these early processes. Vertebrate Development: Maternal to Zygotic Control brings together chapters from experts in various disciplines describing the latest advances related to this important developmental transition. Each chapter is a synthesis of knowledge relevant to all vertebrates, with details on specific systems as well as comparisons between the various studied vertebrate models. The editorial expertise encompasses the fields of major vertebrate model systems (mammalian, amphibian and teleost) ensuring a balanced approach to various topics. This unique book—with its combination of in-depth and up-to-date basic research, inter-species comprehensiveness and emphasis on the very early stages of animal development—is essential for research scientists studying vertebrate development, as well as being a valuable resource for college educators teaching advanced courses in developmental biology.

This volume presents a synthesis of basic biological and conservation data for more than 30 species of sturgeons (Acipenseridae), paddlefishes (Polyodontidae) and their fossil allies in the order Acipenseriformes. Since the Jurassic, the four families of sturgeon-like fish have been restricted to the Holarctic, where until very recently they flourished in most major river systems. Today, however, virtually all species of sturgeons and paddlefishes face difficult conservation issues. Papers in the first section of this volume examine paleontology, systematics, evolution and basic biology of Acipenseriformes. The second section of this volume details current conservation status for most of the world's living species of Acipenseriformes. These papers mark the first attempt to make such a global review of recent data from across the northern hemisphere. The emerging picture is discouraging, for negative anthropogenic impacts range from overfishing to water pollution, to dams and water diversion projects, and all species are threatened to some degree. The third section of the volume considers specific human impacts and responses to conservation issues. These include: the Aral Sea ecological disaster and its impact on native sturgeons; a review of methods for restoring sturgeon populations; the use of molecular techniques in developing conservation strategies; the extreme sensitivity of sturgeons and paddlefishes to overfishing; and the history of a recently convicted caviar poaching ring. The volume's summary reviews the status of all extant species and notes future directions for research on behavior, ecology and population biology that could lead to better co-ordinated international conservation efforts.

As the largest group of extant vertebrates, fish offer an almost limitless number of striking examples of evolutionary adaptation to environmental and biotic selection pressure. The most diverse of all vertebrate groups, the higher taxa of fish traditionally have been classified by morphology and paleontology, with a much smaller input of cytogenetic information. DNA sequence data are exerting an increasingly strong influence on modern fish systematics, challenging the classification of numerous higher taxa ranging from genera to orders. The most fruitful approach, however, involves synthetic analyses of morphology, molecular phylogenetics, comparative karyology, and genome size. Karyotypes of more than 3400 species/subspecies are arranged here by fish systematics and include a list of genome size, sex chromosomes, B chromosomes, polyploidy, and locality of material fish, among others. This volume enables both beginners and advanced researchers to survey the existing literature and facilitates the implementation of an integrative approach to fish systematics. The first book on fish chromosomes in nearly 15 years, it is also the most comprehensive.
