Vegetation of carbonate outcrops in mountains of central Argentina. In mountains of Central Argentina, which have severe fragmentation and replacement of natural vegetation, rocky outcrops are important habitats for biodiversity conservation, as refuges for endemic and rare species.

Vegetation of carbonate outcrops in mountains of central Argentina. In mountains of Central Argentina, which have severe fragmentation and replacement of natural vegetation, rocky outcrops are important habitats for biodiversity conservation, as refuges for endemic and rare species. In this paper,we explore the local compositional variation of vegetation in calcium and dolomitic outcrops of Sierras deCórdoba and compare associations between different geochemical types and floristic composition alonga local altitudinal gradient. Four adjacent outcrops of different geochemical types located in different positions in a local elevation gradient from 1000 to 1800 m.a.s.l. were selected and cover-abundance ofall vascular plants at 216 rélevés, was estimated. Significative differences of compositional vegetation attributes occurred between the different lithologies and altitudinal strata. At the local scale, the floristic composition appeared related to the geochemical typology of outcrops and this pattern is overlapped with altitude. It was possible to establish relationships between the presence of different vascular plants and different types of calcitic and dolomitic rocks, independently of their position in the altitudinal gradient.The importance of these variables in structuring the habitat and filtering of species is confirmed, and itsimportance in looking for priorities in conservation of these singular habitats. En las montañas del centro de Argentina, con una intensa fragmentación y reemplazos dela vegetación natural, los afloramientos rocosos constituyen hábitats importantes para la conservaciónde la biodiversidad, como refugios de especies endémicas y raras. En este trabajo se exploró lavariación composicional local de la vegetación en afloramientos de mármoles cálcicos y dolomíticosde las sierras de Córdoba y se compararon las asociaciones entre diferentes tipologías geoquímicas yla composición florística en un gradiente altitudinal. Se relevaron cuatro afloramientos adyacentes detipologías geoquímicas diferentes localizados en diferentes posiciones en un gradiente de altitud desde1000 hasta 1800 msm, estimándose abundancia-cobertura de todas las plantas vasculares en 216censos. Los atributos composicionales estructurales de la vegetación revelaron diferencias significativasentre litologías similares en diferentes estratos altitudinales y entre diferentes litologías para un mismoestrato altitudinal. La composición florística local está relacionada con la tipología geoquímica de losafloramientos y la altitud se sobrepone a ese patrón. Se establecieron relaciones entre la presencia dediferentes especies vegetales y tipologías de rocas calcíticas y dolomíticas de manera independiente asu posición en el gradiente de altitud. Se confirma la importancia de estas variables en la estructuracióndel hábitat y filtrado abiótico de especies y la importancia de su conocimiento para establecer prioridadesen su conservación.
