When asked by the General Editor to prepare a book-length treatment concerning the nature of the Canary Islands, our aims were rather ambitious. A general monograph was to be written, embracing all the disciplines of natural history applicable to these islands, and over twenty scientists were approached for contributions. However scientists are 'time machines' ; our proposed list of contents has changed a good many times. Cooporation of other authors was gained and, finally, a fairly rounded project appeared revealing different and lesser known aspects of Canary Island Nature. Since Centuries the Canary Islands have attracted the attention of travellers. Earliest reports may be traced back some two thousand years but real scientific investigation began about 1800, the time of Alexander von Humboldt and his visit to the islands; older reports are scarce, sometimes rather confusing because of geographic inaccuracies. But the 19th Century will remain as the century of fundamental explorations, connected with names such as Leopold von Buch, F. C. MacGregor, Sabin Berthelot, Philip Barker Webb, J. Viera y Clavijo, F. von Fritsch, C. Bolle, D. H. Christ, O. Simony, G. Hartung, H. Mayer etc. , all familiar and intimately connected with our knowledge of the natural history of the archipelago. Even the much criticised Ernst Haeckel has provided us with lively descriptions of his visit to one of the 'Fortunate Islands'. The 20th Century brought new interest, new fields to be explored, and new expeditions to the islands.
The volcanic and oceanic nature of the Canary Islands, its rich plant biodiversity and high rate of endemism, as well as the relict character of some of its plant communities make it a territory of great biological interest. The main geographic, climatic, bioclimatic, biogeographic and floristic features of the Islands are shown and related to the distributional pattern of potential communities along an altitudinal gradient. Current vegetation units and their ecology are described and illustrated with numerous pictures. Potential vegetation units are summarized and comprehensive maps of the potential natural vegetation for each island are given. Human impact on the natural landscape, the occurrence of invasive plants, and the probable impact of climate change on the flora and vegetation are discussed. The conservation status of flora and vegetation are assessed. Four appendixes include a syntaxonomical scheme, a brief history of botanical studies and explorations in the Islands, ethnobotanical notes, and a list of selected literature.
Isolation, extinction, conservation, biodiversity, hotspots.
A fascinating study of the important role of biology in European expansion, from 900 to 1900.
An essential guide to birds of the Canary Islands, an area with an impressive range of species This comprehensive guide covers all bird species found in the Canary Islands, a group of beautiful islands that are home to endemics such as the Blue Chaffinch, and are one of the best places in the world to see a number of rare species. The book covers every species recorded in the Canary Islands, including vagrants. Included are 73 colour plates illustrating more than 300 species, with text on facing pages for quick and easy reference. The concise text covers status, distribution, habitat, identification, voice and taxonomy. Also incorporated is an introduction with information on the geography and climate of the Canary Islands, plus habitats, birding sites and conservation.
Oceanic islands offer biologists unparalleled opportunities to study evolutionary processes and ecological phenomena. However, human activity threatens to alter or destroy many of these fragile ecosystems, with recent estimates suggesting that nearly half of the world's insular endemics are threatened with extinction. Bringing together researchers from around the world, this book illustrates how modern research methods and new concepts have challenged accepted theories and changed our understanding of island flora. Particular attention is given to the impact of molecular studies and the insights that they provide into topics such as colonisation, radiation, diversification and hybridisation. Examples are drawn from around the world, including the Hawaiian archipelago, Galapagos Islands, Madagascar and the Macronesian region. Conservation issues are also highlighted, with coverage of alien species and the role of ex situ conservation providing valuable information that will aid the formulation of management strategies and genetic rescue programmes.
Population theory.
Biologists searching for a resource that explores all of the exciting changes that have occurred recently in the field will turn to this eighth edition. It offers insight into the multidisciplinary nature of the field, presenting a sound historical base, up-to-date coverage, and a look at the latest controversies. The authors evaluate conflicting theories and provide a reasoned judgment as to which is preferable. In a new chapter the authors examine marine biogeography, so that biologists can compare and analyze the data, patterns and problems arising from continental, marine and island biogeography.
