Small but important: The woody vegetation communities on the sandstone outcrops of Teyú Cuaré (Misiones, Argentina)
Rock outcrops are commonly harsh environments that maintain important components of biodiversity because they are inhabited by endemic or relictual species. We studied the diversity and structure of the woody plant of rupestrian vegetation located in the San Ignacio department (Misiones, Argentina),...

Rock outcrops phytosociology rupestrian vegetation endemic species. Rock outcrops are commonly harsh environments that maintain important components of biodiversity because they are inhabited by endemic or relictual species. We studied the diversity and structure of the woody plant of rupestrian vegetation located in the San Ignacio department (Misiones, Argentina), and evaluated the beta diversity with respect to other neighbor vegetation formation (i.e. forest and savanna). We found 32 species, most of them were arboreal nonetheless of small size. Qualea cordata (Mart.) Spreng., Monvillea euchlora Backeb., Ocotea lancifolia (Schott) Mez and Myrciaria delicatula (DC.) O.Berg were the most important in the community structure. Rupestrian vegetation showed an intermediate woody species diversity compared to nearby forests and savannas. We found a high beta diversity between rupestrian formation and the other physiognomies mainly established by richness difference. Rock environments are high-priority conservation level because their singular plant communities inhabit specific edaphic and geomorphic conditions, occurring only in a restricted geographical range. Pequeños pero importantes: las comunidades de vegetales leñosa de los afloramientos de arenisca de Teyú Cuaré (Misiones, Argentina). Los afloramientos rocosos son ambientes comúnmente rigurosos que mantiene importantes componentes de la biodiversidad por estar habitados por especies endémicas o relictuales. El objetivo del presente estudio fue evaluar la diversidad y estructura de la planta leñosa de la vegetación rupestre ubicada en el departamento de San Ignacio (Misiones, Argentina) y evaluar la diversidad beta con respecto a otras formaciones vegetales vecinas (esto es bosque y sabana). Se encontraron 32 especies de plantas leñosas, la mayoría arbóreas de pequeño tamaño. Qualea cordata (Mart.) Spreng., Monvillea euchlora Backeb., Ocotea lancifolia (Schott) Mez y Myrciaria delicatula (DC.) O. Berg fueron las más importantes en la estructura de la comunidad. La vegetación rupestre del conjunto de afloramientos estudiados mostró una diversidad leñosa media en comparación con las formaciones de bosque y sabana, con una alta diversidad beta, principalmente estructurada por la diferencia de riqueza. Estos ambientes tienen una alta prioridad para la conservación, debido a que las comunidades vegetales son fisionómica y florísticamente singulares, además de estar en condiciones edáficas y geomorfológicas con una expresión geográfica restricta.

Rock outcrops are commonly harsh environments that maintain important components of biodiversity because they are inhabited by endemic or relictual species. We studied the diversity and structure of the woody plant of rupestrian vegetation located in the San Ignacio department (Misiones, Argentina), and evaluated the beta diversity with respect to other neighbor vegetation formation (i.e. forest and savanna). We found 32 species, most of them were arboreal nonetheless of small size. Qualea cordata (Mart.) Spreng., Monvillea euchlora Backeb., Ocotea lancifolia (Schott) Mez and Myrciaria delicatula (DC.) O.Berg were the most important in the community structure. Rupestrian vegetation showed an intermediate woody species diversity compared to nearby forests and savannas. We found a high beta diversity between rupestrian formation and the other physiognomies mainly established by richness difference. Rock environments are high-priority conservation level because their singular plant communities inhabit specific edaphic and geomorphic conditions, occurring only in a restricted geographical range. |
