Robles in Lagunas de Epulauquen, Argentina: previous and recent evidence of their distinctive character
The northernmost 'robles' of Argentina, located in Lagunas de Epulauquen (northwest Patagonia), are considered a population of Nothofagus obliqua, even though they differ in some respects from individuals of other populations of the species. In order to analyse a possible genetic basis of...
