The regions of the world which experience a mediterranean type climate, with a cool wet season alternating with a hot dry summer, contain some of the world's most attractive landscapes. In the Old World, the mediterranean landscapes became the cradle of civilization; other mediterranean areas of the world have attracted considerable populations for many centuries. These large human populations have exerted consid erable stress on the fragile ecosystems which developed in these sunny, but droughted, fire-prone land scapes. The mediterranean landscape has thus become one of the most threatened in the world. In recent years much has been learned about the structure and function of mediterranean-type ecosystems (Di Castri and Mooney 1973, Mooney 1977, Thrower and Bradbury 1977, Mooney and Conrad 1977, Specht 1979, 1981, Miller 1981, Di Castri et at. 1981, Conrad and Oeche11982, Queze11982, Margaris and Mooney 1981, Kruger et ai. 1983, Long and Pons 1984, Dell et ai. 1986, Tenhunen et ai. 1987). Much of this research has been fostered under the International Biological Program (IBP), UNESCO Man and the Biosphere Program (MAB) and, recently, the International Society of Mediterranean Ecologists (ISOMED). To facilitate intercontinental comparisons, many of these studies have concentrated on a limited number of intensive sites thought to be representative of a general region.

Human activities are causing species extinctions at a rate and magnitude rivaling those of past geologic extinction events. Exploring mediterranean-type ecosystems - the Mediterranean Basin, California, Chile, Australia, and South Africa - this volume addresses the question whether biological diversity plays a significant role in the functioning of natural ecosystems, and to what extent that diversity can be reduced without causing system malfunction. Comparative studies in ecosystems that are similar in certain respects, but differ in others, offer considerable scope for gaining new insights into the links between biodiversity and ecosystem functioning.

This publication presents a comprehensive treatment of the genus Bromus L. and its occurrences on the Iberian Peninsula. Previously, Bromus had only been given limited attention in a number of floras (e.g. Willkomm, 1861; Losa Espana, 1961). A complete review of literature on the subject is used as the base of this review of Bromus, and nearly 4000 specimens of Bromus were studied and compared to other Bromus specimens from outside the Iberian Penisula. A list of sampling locations of the specimens is provided, documenting the location (UTM coordinates), country, gathering date, ecology, collector and the sheet number of the respective herbarium.

The key to preserving and managing biodiversity is understanding which processes are important at different scales, and how changes affect different components of biodiversity. In this book, existing theories on diversity are synthesised into a logical framework. Global and landscape-scale patterns of biodiversity are described in the first section. In the second, the spatial and temporal dynamics of diversity are emphasised. The third section develops an integrated set of mechanistic explanations for diversity patterns at the levels of population, community, ecosystem and landscape. Finally, case studies examine diversity patterns in marine and terrestrial ecosystems and the effects of biological invasions. The book concludes with a discussion of the economics of preserving biological diversity. This book will interest research workers and students of ecology, biology and conservation.

Predation is an ecological factor of almost universal importance for the biol ogist who aims at an understanding of the habits and structures of animals. Despite its pervasive nature opinions differ as to what predation really is. So far it has been defined only in negative terms; it is thought not to be par asitism, the other great process by which one organism harms another, nor filter-feeding, carrion-eating, or browsing. Accordingly, one could define predation as a process by which an animal spends some effort to locate a live prey and, in addition, spends another effort to mutilate or kill it. Ac cording to this usage of the word a nudibranch, for example, that feeds on hydroids would be a predator inasmuch as it needs some time to locate col onies of its prey which, after being located, scarcely demand more than eating, which differs little from browsing. From the definition just proposed consumption of the prey following its capture has been intentionally omit ted. Indeed, an animal may be disposed of without being eaten. Hence the biological significance of predation may be more than to maintain nutrition al homeostasis. In fact, predation may have something in common with the more direct forms of competition, a facet that will be only cursorily touched upon in this book.

In recent years considerable progress has been made in elucidating wood decay mechanisms. This basic knowledge not only has the potential to develop alternative environmentally-benign wood preservatives, but may also impact other areas such as bioremediation and pulp and paper. This book will summarize the latest knowledge of the developments, potential impacts, and applications from some of the world's leading experts.
