en A substantial fraction of stored freshwater available on neotropical inselbergs is impounded within the rosettes of bromeliads. Their high water retention capacity can potentially have an outcome on the inselberg community as well as on the surrounding environment. However, there are no studies measuring and extrapolating the water retention cap...

Questions Environmental filters limit the set of potentially coexisting species in plant communities. Paradoxically, some of the world's most biodiverse communities are subjected to strong abiotic filters. We explored how environmental heterogeneity provides conditions for niche segregation in a harsh megadiverse ecosystem, focusing on fine‐scale f...

Granite and/or gneiss inselbergs are excellent examples of geomorphologic stable island habitats, considered as Old, Climatically Buffered, Infertile Landscapes (OCBILs). However, contrary to oceanic islands, their underlying drivers of diversity patterns remain to be investigated. Here, we studied 24 inselbergs in south-eastern Brazil, aiming to u...

Background Isolated monoliths of granitic and/or gneissic rock rising abruptly from the surrounding landscape are known as inselbergs. Dome-shaped inselbergs are common throughout the Atlantic Forest in south-eastern Brazil, a region known as Sugarloaf Land (SLL). This study aimed to create the first checklist of vascular plant species occurring on...

Larger flowers greatly increase among-individual pollen exchange within populations. However, water costs associated to transpirational cooling also increase with increasing flower size. Overall, the interplay between pollen and resource limitation determine the intensity of selection on flower size and this process is mostly dependent on gender an...

Inselbergs are granitic and gneissic rock outcrops, which rise abruptly above their surroundings, located in temperate and tropical regions They are considered as terrestrial islands, due to harsh environmental conditions (e g lack of soil and water, high temperatures) their vegetation is clearly distinguished from the surrounding matrix The widesp...

o Pão de açúcar, ícone das olimpíadas de 2016, é um dos afl oramentos rochosos mais famosos do mundo. entretanto, além do rio de janeiro, outras regiões do país também abrigam essas formações de composição principalmente granítica e/ou gnáissica, denominadas inselbergs. essas 'ilhas terrestres' inseridas na mata atlântica, bem como em outros biomas...

The Atlantic forest is among the hottest hotspots for biodiversity conservation. Within this biome, inselbergs are isolated granitic and gneiss rocks that rise sharply above the lowland surrounding forests. Due to prevailing stressful conditions and resource paucity of inselbergs, distinguished plant communities are formed in these rocky-associated...

Os afloramentos rochosos ocorrem de forma dispersa sobre ampla porção do globo terrestre. Estes são locais de dimensões restritas, muitas vezes de difícil acesso, baixo interesse econômico, e menor diversidade que a da Mata Atlântica (CONCEIÇÃO & GIULIETTI, 2002; CONCEIÇÃO et al., 2007a; RIBEIRO et al., 2007; MOURA et al., 2011). Apesar disto esses ambientes vêm sendo pesquisados em todo o mundo e sob diferentes abordagens, em função de suas especificidades e relevância para pesquisas em áreas diversas, como ecofisiologia, evolução, biogeografia e ecologia (SCARANO, 2007; RIBEIRO et al., 2007). Na paisagem da região sudeste brasileira os afloramentos rochosos graníticos e gnáissicos são muito frequentes, com destaque para os cenários encontrados nos Estados do Rio de Janeiro e Espírito Santo, com centenas de pontões facilmente visíveis e alguns que apresentam desníveis acima de 1.000 m em relação à matriz florestal circundante (MOURA et al., 2011). Devido ao isolamento geográfico, estas regiões são consideradas como refúgios ecológicos, centro de dispersão de plantas suculentas e ressurreição (poiquilohídricas) e elevado grau de endemismo. Embora estes afloramentos rochosos sejam frequentes, ainda são poucos os estudos ecológicos sobre a vegetação que neles ocorrem. A escassez desses estudos dificulta análises comparativas que são de suma importância para a compreensão e conservação desse tipo singular de vegetação (CAIAFA & SILVA, 2005).
