内容説明
This volume is based on a workshop on "Population Biology of. Plants The Interfaces (Genetics, Physiology, Demography, Biogeography)", with a specific profile on "Diversification of Plant Populations in relation to Modes of Reproduction and Dispersal Genetic and Physiological Mechanisms", held in Port-Camargue, France, from May 21-25, 1984. This workshop was initiated by the "Unit of Population and Community Biology", in Montpellier, and sponsored by the NATO Scientific Affairs Division (ARW grant 876/83) and by the CNRS (Table ronde). All populations are subjected to environmental "screening". Given a genetic diversity whose expression can be modified by a degree of demographic and individual plastici ty (at the morphological and physiological levels), they present a structure related to their environment. Ideally populations should be studied simultaneously from the point of view of the population geneticist, the physiologist and the demographer . These specific approaches only become fully meaning full in the "light of Evolution".
Among the evolutionary forces that quantitatively act on the frequencies, objects of interest of workers specialising in Population Biology are selection and drift. An other main object of the study must be dispersal. But, its playing extent - relative to the other forces - in the adjustment to the environment is not fully recognized.
