Estratto del testo

Since 1992, the International Convention on Biodiversity has emphasized the need for conservation of species and natural environments. Much discussion has involved the biological diversity of tropical forests and terrestrial ecosystems, as well as the consequences, often negative, of human activity on the long-term evolution of these environments. Although freshwaters did not always receive enough attention, their present state is often worrying.

Yet continental aquatic biodiversity displays interesting characteristics:

  • a relatively high rate of endemicity, particularly in lakes and rivers that were isolated for millions of years such as the East African great lakes, Lakes Baïkal, Biwa, and Titicaca, as well as the forest basins of the Amazon and the Congo, to name a few;
  • high genetic variability between populations of species with an enormous geographic distribution, but occupying hydrographic systems that have been isolated for more or less long periods;
  • a disproportionately large num...
