Useful resources in nature have ever been screened based solely on actual experiences of mankind since a long time, and this is true even at this moment when our science has greatly advanced. New useful materials are urgently demanded to be sought in nature by human beings, for they have a rapid increase of their population as well as rapid diversification of their life style. In reply to such a heavy pressure, more effective way is to be found out in introducing useful materials supplied more safely to mankind. To establish a reliable guide in screening unknown materials from the wild plants, it is expected to have more certain system of biodiversity. If we will known correct relationships among plant species and sufficient information in each species, it will be possible to infer what materials are in which species.

Biological invasion, an issue of growing importance due to the significant increase in international transportation and trade, can disturb the balance of local ecosystems and even destroy them. This collection of papers presented at the International Conference on Assessment and Control of Biological Invasion Risks held in August 2004 at Yokohama National University discusses risk assessment, risk management and eradication. It also includes contributions reporting on the current status of invasion and the properties of alien species in East Asia.

ASSESSMENT AND CONTROL OF BIOLOGICAL INVASION RISKS

Peter H. Raven

A modern approach to understanding the evolution and diversification of land plants, one of the most exciting areas of plant systematics. It consists of three sections - origin and diversification of primitive land plants; origin and diversification of angiosperms; speciation and mechanisms of diversification - each section corresponding to a major area in plant evolution. In each case, data from molecular, morphological, and paleontological approaches are presented, backed by recent progress and new findings, together with proposals for future research. A guide to the latest in plant systematics, heightening awareness of prospective future problems.
