Efectos de la remoción de la biomasa aérea de las especies más abundantes sobre la estructura de un mallín patagónico
I analyzed the effect of the removal of the aerial biomass of the most abundant species on the plant community structure of a flooded meadow, located in NW Patagonia. The experimental treatments consisted of: (i) the removal of the aerial biomass of the dominant species; (ii) the removal of the aerial biomass of the dominant and the co-dominat species. The following hypothesis was tested: the dominant and the co-dominat species limit the presence and abundance of other species; as a result, species diversity and/orspeciesrichness would increase afterspeciesremovals. Significant differencesin species responses were observed only in two species, one year after the removals of species were performed. No significant differences in species diversity and species richness were observed. It is suggested that the removed species have a higher reposition rate of removed tissues than the rate of occupance of the open space by the other species.
