Abstract

Fungi are among the most versatile and diverse groups of organisms in their morphology, life cycles, and ecology. This has provided endless fasci­ nation and intrigue to those who have studied fungi, but it has also made it difficult to understand fungal biology from the perspective of the broader fields of evolution, ecology, genetics, and population biology. That is changing. Details of fungal biology have been elucidated at an exciting pace, increasingly allowing us to understand fungi on the bases of general biological principles. Moreover, many who study fungi have lately emulated some of the great mycologists and plant pathologists of the early years in applying an insight born of broad perspective. This change has been particularly apparent in fungal population biology. In this book, many of those at the forefront of that change summarize, integrate and comment on recent developments and ideas on populations of fungi. By taking a broad perspective, they show how new information on fungi may contribute to concepts and ideas of biology as a whole. Just as important, they contribute to further invigoration of fungal population research by illuminating mycology with new ideas and concepts, derived in part from other biological fields.

Abstract

Scientific reserach on natural disasters is now implementing new methodologies and aproaches as consequences of: 1. mutating impact of extreme natural events in response to societal change like land use, lifelines, communications, transportation, etc.; 2. development which claim for new urban and industrial territories, often in hazard prone areas; 3. impact of modern society on natural climate variability (climate change) and con­ sequently, on spatial and temporal frequency of extreme events related to hydro­ logical cycle. As consequence of the above mentioned items it is necessary to develop a global approach to territory in order to understand reciprocous influence between climate dynamics with their extreme consequences like floods and landslides and socio-eco­ nomic development. In such a way, and in response to societal change, scientific re­ search on floods and landslides is beginning to loose the classical mono disciplinary approach and it is starting to be a science of the hydrological processes. The course on "Floods and Landslides: integrated risk assessment" held in Orvieto (Italy) 19-26 may 1996, has been organised by the European Commission specifically with the aim of transferring to young European scientists these new views, in order to contribute to a future scientific community, capable to face with the future environ­ mental problems.
