| Résumé : |
"The proposition that the migration of organisms between habitat patches could be enhanced bycorridors has been much discussed among conservation biologists. But the few experimental studies support-ing the usefulness of corridors have all concerned animal species. We investigated the role of corridors in seeddispersal, studying population genetic and demographic structure in metapopulations of the rare, pond-dwelling, autogamous plant species Ranunculus nodiflorus L. in the Fontainebleau Forest (France). Differenti-ation on three polymorphic isozyme markers was strong among local populations (ponds) within metapopu-lations (sites) and moderate among metapopulations. Partial Mantel tests revealed that the connection ofponds through temporarily flooded natural corridors, facilitating seed migration, had a strong negative effecton genetic differentiation between local populations and that a pond was more likely to be colonized whenconnected by corridors to other occupied ponds. Thus, corridors are probably a key element of landscapestructure for metapopulation dynamics in R. nodiflorus. From a conservation perspective, our results suggestthat corridors could increase the chance of persistence of plant species living in fragmented habitats by pro-moting seed dispersal between habitat patches." |
