Resumen

MUNOZ, Fernando et al. COMPOSITION, STRUCTURE AND DIVERSITY OF POPULATIONS OF NOTHOFAGUS GLAUCA LOCATED IN THE MEDITERRANEAN ZONE OF CHILE. Gayana Bot. [online]. 2013, vol.70, n.1, pp.82-91. ISSN 0717-6643.  http://dx.doi.org/10.4067/S0717-66432013000100009.

The forests of Nothofagus glauca are located in the mediterranean zone of central Chile. Its elimination to enable soil for agricultural, forestry, more cattle use as well as the utilization of its wood for fuelwood and coal, reduced drastically its surface. Forests of N. glauca, that are located in the Coast and Andes chain mountain of the central zone of Chile, were studied. Across forest inventory, during summer of 2008 and 2009, it was recorded the composition, structure and diversity of the communities inhabited by N. glauca, some of which were selected to be climbed for seed collection to be used for genetic diversity studies. The results indicated a great difference between the forests of N. glauca located in Coast and the Andes. The forests of the Coast chain mountain, presented major species richness of each stand, dominance and diversity of species between communities. In all studied forests, N. glauca was the predominant species in all strata of crown (dominant, codominant, suppressed), with diameter class structures principally of the type "inverse J-shaped". The best seed production, in quantity and quality, was registered in Coast chain mountain forest.

Palabras clave : Nothofagus; plant communities; alpha and beta diversity; species richness.
