  • Erosion of plant genetic resources : causes and effects
  • Special issue. Agriculture - systems - landscapes - resources
  • of erosion of crop genetic resources.
  • Replacement of a diversity of landraces with few unified modern varieties as part of a wider agricultural modernization is the main cause of genetic erosion. Genetic erosion has negative developmental effects when the modern varieties which replace
  • Genes are not information: rendering plant genetic resources untradeable through genetic restoration practices

  • In this paper, the A. argues that a Midwestern plant conservation science institution (MPCSI) challenges genetic commodification through distinct knowledge-making and social practices. He analyzes the socionatural implications of this institution’s
  • use of genetic technology in native ecosystem restoration. He focuses on specific techniques used by the MPCSI’s scientists to view genes as embodied relational entities, rather than abstract information. He details the MPCSI’s emerging relationship
  • with commercial seed nurseries to illustrate how decommodification is integral to commodification. Finally, he argues that that although the MPCSI’s genetic restoration strategy necessitates limited market engagements, their scientific practices and institutional

  • L'A. met l'accent sur la conservation des ressources en Amérique latine, et tout particulièrement sur la nécessité d'étudier le potentiel de la flore autochtone de la région du Sertao, au nordest du Brésil. Il est urgent de trouver des moyens pour
  • protéger ces ressources en vue de leur utilisation future. (OP).
  • The South-Italian city - a cultural - genetic type of city in Mediterranean regions.
  • Ethnobiodiversity and plant genetic resources in the Alp-Balkan-Carpath-Danube (ABCD) area
  • Genes and biogeographers incorporating a genetic perspective into biogeographical research
  • Genetic applications in biogeography
  • The A. provides an overview and assessment of how geographers could potentially incorporate a genetic perspective into biogeographical research focused on past, present, and likely future species distributions. This effort is especially timely
  • as the lat 2 decades have seen monumental advances in the knowledge of how organismal molecular biology functions to create the physiological and reproductive characteristics of species and their respective populations. In addition, these genetic studies also
  • Genetic applications in biogeography
  • After a brief overview of selected molecular markers, the AA. discuss lines of biogeographic inquiry involving genetic analyses where geographers can potentially make the greatest contribution. Examples from their own genetically-based biogeographic
  • research are provided. These include examination of spatial patterns of genetic variation, inferences about paleoenvironmental conditions, determination of evolutionary relationships, and analysis of genetic effects of human activity.
  • The role of molecular genetics in sculpting the future of integrative biogeography
  • The AA. review the expanding role of molecular genetics in the emergence of a vibrant and vital integrative biogeography. A proliferation of different approaches, sequences, and genomes have provided for the integration of a biogeography of the Late
  • Neogene with other Earth and biological sciences under the rubrics of phylogeography, landscape genetics, and phylochronology. The AA. illustrate how a molecular genetics framework has provided robust and novel reconstructions of historical biogeographical
  • pattern and process in 3 different systems, and finish with some thoughts on the role a molecular genetic-based biogeography will play in predicting alternative futures of biodiversity.
  • Genetics and the environment: understanding geographical variations in the incidence of childhood diabetes
  • Childhood diabetes is thought to result from exposure to environmental factors which trigger a pathogenic response in genetically susceptible children. Evidence of marked spatial and temporal variation in the incidence of childhood diabetes around
