How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Perennial plants create productive and biodiverse hotspots, known as fertile islands, beneath their canopies. These hotspots largely determine the structure and functioning of drylands worldwide. Despite their ubiquity, the factors controlling fertile islands under conditions of contrasting grazing by livestock, the most prevalent land use in dryla...
The geodiversity of rocky ecosystems includes diverse plant communities with specific names, but their continental‐scale floristic identity and the knowledge on the role of macroclimate remain patchy. Here, we assessed the identity of plant communities in eastern Brazil across multiple types of rocky landscapes and evaluated the relative importance...
Inselbergs are azonal formations found scattered in different biomes globally. The first floristic list focusing on an inselberg in the Brazilian Amazon is presented here. We aimed to investigate floristic and phylogenetic connections among Neotropical inselbergs and analyze whether environmental variables act as a filter of plant lineages. We used...
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...
