ETAT D’ALERTE DE LA BIODIVERSITE DIVERSITE TAXONOMIQUE GESTION DES ESPECES PROTEGEES |
Résumé : |
Taxonomic and genetic diversity which seems essential for health, agriculture and ecosystem function, are eroded as wildlands are converted to other uses and many species have become extinct as a result and thousands of others face a similar fate. Humans use tens of thousands of species in their daily livesfor food, shelter, medicines and diverse forms of commerce. As population pressures increase and more and more people make use of other species for subsistence, managing these resources in a sustainable manner is not easy. Modern forms of transportation have reached all corners of the globe so that people, whatever their economic circumstances, are now more mobile than at any other time in human history. As a consequence, thousands of species are transported around the world so new diseases are emerging and agricultural systems are exposed to a multitude of new crop pests; the natural structure and function of ecological communities are being torn apart by the introduction of exotic species and intricates distributions of species produced over thousands of years are being shuffled.
Of all the biological information that is needed to manage the world’s species, the most fundamental is that provided by the discipline of systematic biology. Discovery and description of species, then phylogenetic analysis, classification and biogeography provide basic biological information about species, including name, characterization, relationships about species and geographic distribution, thus establishing the foundation for all the other biodiversity sciences such as ecology, population biology,genetics and behavior. Taken in agregate, these components support the ultimate aim of systematics to know and to understand the taxonomic and phylogenetic of life on earth.
The continuing loss and degradation of the world’s biological resources comprises the ability of nations to create a sustainable future for their citizens and managing these resources necessitates an increased commitment on the part of the world community to support the biodiversity sciences,especially in the species-rich countries where scientific capacity is least developed. This should include programs to build new or to improve existing infrastructure,enhance human resources and establish a worldwide biodiversity information network.
