This book provides an overview of the importance of research on relict species and presents conclusions and findings on the conservation of these species. There are relict species and populations from nearly all plant and animal groups and they contribute substantially to biodiversity across the globe. Current diversity patterns are influenced by both historic and recent ecological conditions. Relict species are of particular importance, as they usually suffer more severely from human activities than do non-relict populations; the situation is also potentially critical, as many relict species and populations have the potential to colonize large areas when the climate changes.
The more than 27 contributions in this book highlight the history and status of today's relict species and populations and apply molecular genetics, morphometry, modelling and conservation biology to describe the past and present situations and to predict future trends of relict species' distribution.
Mankind has evolved both genetically and culturally to become a most successful and dominant species. But we are now so numerous and our technology is so p- erful that we are having major effects on the planet, its environment, and the b- sphere. For some years prophets have warned of the possible detrimental consequences of our activities, such as pollution, deforestation, and overfishing, and recently it has become clear that we are even changing the atmosphere (e. g. ozone, carbon dioxide). This is worrying since the planet's life systems are involved and dependent on its functioning. Current climate change - global w arming - is one recognised consequence of this larger problem. To face this major challenge, we will need the research and advice of many disciplines - Physics, Chemistry, Earth Sciences, Biology, and Sociology - and particularly the commitment of wise politicians such as US Senator Al Gore. An important aspect of this global problem that has been researched for several decades is the loss of species and the impoverishment of our ecosystems, and hence their ability to sustain themselves, and more particularly us! Through evolutionary time new species have been generated and some have gone extinct. Such extinction and regeneration are moulded by changes in the earth's crust, atmosphere, and resultant climate. Some extinctions have been massive, particularly those asso- ated with catastrophic meteoric impacts like the end of the Cretaceous Period 65Mya.
