Download or read book The Invertebrates written by R. S. K. Barnes and published by John Wiley & Sons. This book was released on 2009-04-13 with total page 507 pages. Available in PDF, EPUB and Kindle. Book excerpt: The majority of undergraduate texts in invertebrate zoology (of which there are many) fall into one of two categories. They either offer a systematic treatment of groups of animals phylum by phylum, or adopt a functional approach to the various anatomical and physiological systems of the better known species. The Invertebrates is the first and only textbook to integrate both approaches and thus meet the modern teaching needs of the subject. This is the only invertebrate textbook to integrate systematics and functional approaches. The molecular systematics sections have been completely updated for the new edition. Strong evolutionary theme which reflects the importance of molecular techniques throughout. Distills the essential characteristics of each invertebrate group and lists diagnostic features to allow comparisons between phyla. New phyla have been added for the new edition. Stresses comparisons in physiology, reproduction and development. Improved layout and illustration quality. Second edition has sold 14000 copies. Nature of the first edition: 'Students will like this book. It deserves to succeed.'

Download or read book Recent Freshwater Ostracods of the World written by Ivana Karanovic and published by Springer Science & Business Media. This book was released on 2012-01-05 with total page 620 pages. Available in PDF, EPUB and Kindle. Book excerpt: Their story began 500 million years ago, but we only started to get to know them in 1746, when Linné described the first ostracod species. Vividly portraying the freshwater ostracods, this comprehensive reference work gathers the knowledge gained during some 250 years, but which to date has remained scattered throughout the literature. It starts with an introduction to the class Ostracoda with a special focus on freshwater ostracods and highlights practical methods in their study. The systematic part includes an introduction to all families; identification keys for all subfamilies, genera and species; diagnoses for each subfamily and genus; and lists of synonyms and distribution of species. The text is richly illustrated with distribution maps, line drawings of key generic characteristics, and numerous SEM photographs. Serving as an excellent starting point for all further research on freshwater ostracods, it can be widely used not only by ostracodologists, but also by crustaceologists, evolutionists and ecologists.

Download or read book Conservation of Endangered Freshwater Fish in Europe written by Arthur Kirchhofer and published by Birkhäuser. This book was released on 2012-12-06 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two events have recently improved the prospects of protecting fish and their environment in Switzerland: the acceptance of a new Federal Water Protection Law in the plebiscite of May 17th 1992, and the new Federal Legislation on Fisheries, in force since January 1st 1994. With this legal framework, the possibilities for protection of nature and landscape have now considerably improved in Switzerland. The most important aims of the Federal Law on Water Protection are to safeguard the natural habitats of the native flora and fauna and water as the habitat of aquatic organisms. This includes not only the preservation or restoration of water quality in lakes and rivers, but also, in rivers used for hydroelectricity, irrigation or as industrial or other water supplies, the maintenance of sufficient water to fulfill the minimal requirements for fish. However, good quality water in sufficient quan tities alone is not enough to guarantee the survival of fish. Intact fish habitats comprise various phYsical structures including plenty of hiding places, hunting grounds, reproduction and nursery areas within suitable distances from each other. This third aspect of conservation and restoration of aquatic habitats is a central point in the new Federal Law on Fisheries. Whereas the former versions of this law were more concerned with fishery regulations, the recent legislation defines new areas of responsibility for the federal and the cantonal governments.
