Download Evolutionary Genetics of Fishes Book in PDF, ePub and Kindle
It is my hope that this collection of reviews can be profitably read by all who are interested in evolutionary biology. However, I would like to specifically target it for two disparate groups of biologists seldom men tioned in the same sentence, classical ichthyologists and molecular biologists. Since classical times, and perhaps even before, ichthyologists have stood in awe at the tremendous diversity of fishes. The bulk of effort in the field has always been directed toward understanding this diversity, i. e. , extracting from it a coherent picture of evolutionary processes and lineages. This effort has, in turn, always been overwhelmingly based upon morphological comparisons. The practical advantages of such compari sons, especially the ease with which morphological data can be had from preserved museum specimens, are manifold. But considered objectively (outside its context of "tradition"), morphological analysis alone is a poor tool for probing evolutionary processes or elucidating relationships. The concepts of "relationship" and of "evolution" are inherently genetic ones, and the genetic bases of morphological traits are seldom known in detail and frequently unknown entirely. Earlier in this century, several workers, notably Gordon, Kosswig, Schmidt, and, in his salad years, Carl Hubbs, pioneered the application of genetic techniques and modes of reasoning to ichthyology. While certain that most contemporary ichth yologists are familiar with this body of work, I am almost equally certain that few of them regard it as pertinent to their own efforts.

Download Emerging Issues in Fish Larvae Research Book in PDF, ePub and Kindle
This book deals with the fundamentals of key physiological mechanisms involved in the development and growth of fish larvae. Chapters included show how the environmental and nutritional conditions are affecting the developmental process from its molecular basis and how these same conditions also influence the final characteristics of late larvae and fry. This volume provides recent findings on the importance of environmental rhythms, some specific nutrients and the adequate microbial environment in the developmental processes including recent results of current research projects.

Download Biology and Conservation of the European Sturgeon Acipenser sturio L. 1758 Book in PDF, ePub and Kindle
The book aims at synthesizing our current knowledge of Acipenser sturio and its management. This species, one of the most widespread sturgeon species all over Western Europe ranging from the Black Sea to the Baltic, is now on the verge of extinction. Major aspects of its biology and management, including mismanagement, are provided in a historic perspective. Similarly, the changes in the restoration programs (in situ and ex situ) initiated in France and Germany are presented. As the species occurred in sympatry with Acipenser oxyrinchus in Germany and Poland and very recently in France as well, a brief outlook on restoration-management programs of A. oxyrinchus are also provided for both North America and Northern European countries, namely Germany and Poland. As conservation-restoration actions go beyond scientific issues, non-governmental stakeholders and marine professional fishermen’s organizations have also been asked to contribute, and the key role of a French-German cooperation plan is underlined. A part of the book is devoted to perspectives. Illustrations of the European sturgeon, mainly in photographs, but also in stamps and paintings, are presented.

Download Sturgeon biodiversity and conservation Book in PDF, ePub and Kindle
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.
