摘要: Inselbergs sensu lato are isolated, mainly granitic and gneissic, rock outcrops, forming old landscape elements on crystalline continental shields all continents. Mats consisting of monocots occur open rocky slopes, a conspicuous habitat these outcrops. Brazilian lowland inselbergs consist species-rich mats with large numbers endemics Bromeliaceae standing out as characteristic in communities. For the first time, we provide checklist mat-forming bromeliads Brazil investigate whether regional species pool influences diversity inselberg mats. Furthermore, through modelling analysis, looked for potential distribution endemic to inselbergs, expecting that they would show narrower niche width than non-endemic species. Our data indicate existence particular phytogeographical region Atlantic Forest south-eastern Brazil, comprising harbouring highly diverse flora Bromeliaceae, which call Sugar Loaf Land. In addition, our projections reveal smaller predicted areas compared species, former apparently being controlled by climatic factors. addition climate pools, island-like character seems play an important role speciation rupicolous Bromeliaceae.
