Book Description
Refecting what a new generation of conservation biologists is doing and thinking, this vital and far ranging second edition explores where conservation biology is heading. It challenges many conventions of conservation biology by exposing certain weaknesses of widely accepted principles. Combining contributions from both the school and the new breed of conservation biologists, this insightful text focuses primarily on topics the are integral to the daily activities of conservation biologists. Several chapters address ecosystem restoration and biotic invasions as well as the the mechanics of population viability analyses, which are now a routine facet of conservation efforts. A case history approach is implemented throughout the book, with the use of practical real-world examples. Furthermore, an in-depth look at quantitative analyses is presented, allowing for models and mathematical analyses to pinpoint limitations in existing data and guide research toward those aspects of biology that are most likely to be critical to the dynamics of a species or an ecosystem.

Book Description
This is a detailed, illustrated and up-to-date study of the fauna, flora, landscapes, coastal areas and seascapes of the entire Mediterranean Basin, and the Sea itself. Since the publication of the first edition in 1999, the field has advanced in significant ways and this revision is timely.

Book Description
The Mediterranean is an outstanding 'hot-spot' of biological diversity. It is exceptional not only for this, but also because of its long history of interactions between its human inhabitants and the other fauna and flora of the region. The cradle of many civilizations, the Mediterranean region has been host to humans for thousands of years. This book is the first to synthesise our current understanding of the ecology, biology, and geology of Mediterranean animals, birds, and plants, and their habitats. The authors focus on the unique historical determinants and spatial patterns of Mediterranean biodiversity. In particular, the dramatic impacts of long-term human activities on the region's landscapes, flora, and fauna, are considered. This fascinating story will be of interest to researchers and students in ecology, biology, conservation, and geography, as well as to naturalists, and ecotourists visiting this popular holiday region.

Book Description
This assessment is the first overview of the conservation status of 877 northern African freshwater species belonging to five taxonomic groupsfish, molluscs, dragonflies and damselflies, freshwater crabs and aquatic plantsin accordance with the IUCN regional Red List guidelines. Species at risk of regional extinction are mapped and conservation measures are proposed to reduce the probability of future declines.

Book Description
The scientific community has voiced two general concerns about the future of the earth. Firstly, climatologists and oceanographers have focused on the changes in our physical environment, ie climate, oceans, and air. And secondly, environmental biologists have addressed issues of conservation and the extinction of species. There is increasing evidence that these two broad concerns are intertwined and mutually dependent. Past changes in biodiversity have both responded to and caused changes in the earths environment. In its discussions of ten key terrestrial biomes and freshwater ecosystems, this volume uses our broad understanding of global environmental change to present the first comprehensive scenarios of biodiversity for the twenty-first century. Combining physical earth science with conservation biology, the book provides a starting-point for regional assessments on all scales. The book will be of interest to those concerned with guiding research on the changing environment of the earth and with planning future policy, especially in accordance with the Global Biodiversity Convention.

Book Description
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.
