- Abstract
The flora and the vegetation of basaltic outcrops were studied in central Argentina. Coverabundance scores were recorded for 303 plant species in 48 relevés distributed in four outcrop locations ranging between 400 to 900 m asl. The association between the floristic composition and climatic variables were explored through an ordination analysis, and the vegetation of the outcrops was classified into four major types through a classification technique. The floristic composition of the outcrops was significantly associated to climate at the regional scale and the four sites differed in species richness, diversity and dominance. We conclude that well conserved basaltic outcrops from central Argentina are relevant habitats for the conservation of endemic species and over exploited taxa. [ABSTRACT FROM AUTHOR]
