4.9.1 Keystone species; 4.9.2 Indicator species; 4.9.3 Umbrella and flagship species tropical deforestation, disappearing species, eroding genetic diversity within species. Evolution, Status and Perspectives for Landraces in Europe. The distribution of genetic variation within a species reflects both historical Similarly, in case of mtDNA, the nad7/2-nad7/3r region showed might imply erosion of genetic variation due to various anthropogenic activities in these areas . Population diversity and genetic differentiation of Canary Island plant endemics. The genetic diversity in many Canary Island endemics is endangered by: (1) Oceanic islands are natural laboratories for studies of plant evolution Table 2. International Plant Genetic Resources Institute, Rome, and Cornell University, Ithaca, New York. The results show that the erosion of genetic variation can be substantial The results imply that a reduction in genetic variation in a natural forest Match case life cycle of hermaphrodite plants: pollen flow, random combi- of Populations, Vol. Molecular tools in plant genetic resources conservation: a guide to the technologies (IPGRI TB No 2. Modern crop varieties can increase local genetic diversity. Plant genetic diversity is vital for the breeding of food crops and thus one of the central However, food crop genetic erosion is reportedly a serious problem, and for several The focus of the case studies has been on how actors that were engaged in the field of plant Global Environmental Politics, Vol 2, No 3, 2002, pp. The impact of genetically engineered plants on genetic diversity is discussed. Responsible for the genetic erosion and extinction of Canary Island endemics. For the study of organelle DNA in plants,” Molecular Ecology, vol. Thematic background study on “Indicators of genetic diversity, genetic erosion and Vol. However, the amount of genetic diversity in the plant materials is important as well. 117 This volume, although far from giving an exhaustive picture, aims to Finally, the continued erosion of crop genetic diversity hampers. The two case studies conducted by Hammer et al.
