The Isolation of Animal and Plant Populations: Aspects for a European Nature Conservation Strategy,ropean Community is preparing a directive to protect the natural habitats including the wild flora and fauna, aiming at a coherent system of habitats throughout Europe called NATURA 2000. This ambitious directive requires considerable area contribution from the member states, emphasising the protection of the rare and most endangered habitats.

Introductory Remarks: Population Biology, the Scientific Interface to Species Conservation,ith its methods and theoretical background — a large proportion of the tasks which are necessary to make proposals for practical conservation projects..Examples are shown which demonstrate the potentials of population biological analyses on different levels of integration and with different experime

Gene Conservation and the Preservation of Adaptability,mic conservation deserve priority. Adaptability requires the existence of genetic variation that is either adaptively inferior or neutral under the respectively prevailing environmental conditions. On this basis, the significance of genetic load and environmental heterogeneity for the maintenance of

,The Stabilizing Potential of Spatial Heterogeneity — Analysis of an Experimental Predator-Prey Syste of the prey and the reproduction rate of the predator (especially if coupled to its feeding rate) proved to be of great importance. On the other hand, properties which determine the dispersal capacity affected the SPSH only to a minor degree.

Ecological Risk Analysis for Single and Multiple Populations,ed population under environmental and demographic stochasticity. The parameters are the mean value, variation, distribution and correlations of life history traits such as survival, fecundity and migration, and density dependence in recruitment. Probabilities of population decline and extinction are

Genetic and Phenotypic Variation in Relation to Population Size in Two Plant Species: , and ,,esulting in loss of genetic variation and fixation of deleterious alleles. This process often involves a decrease in viability (inbreeding depression) and therefore may significantly affect the probability of extinction of populations. To assess the relevance of these predictions, the amount of gene
