“…Major review papers on terrestrial fauna and flora with dated phylogenies are pertinent here (e.g., Rix et al 2014); More specific syntheses are available for ironstone range flora (Gibson et al 2010(Gibson et al , 2012Yates et al 2011), subterranean fauna (Guzik et al 2010). High Rainfall Zone flora (Sander and Wardell-Johnson 2011); demersal fish (Molony et al 2011;Langlois et al 2012), aquatic biodiversity (Davies and Stewart 2014), and taxonomy of rare and poorly known flora (Wege et al 2015).…”

“…as well as marine fish (Langlois et al 2012) and subterranean fauna (Guzik et al 2010). Inselbergs of granite and banded ironstone have been the focus of special study in this context, each well endowed with narrow range endemics (Jacobi et al 2007;Yates et al 2011;Sander and Wardell-Johnson 2011;Gibson et al 2012;de Paula et al 2015).…”

Background Ocbil theory aims to develop hypotheses explaining the evolution and ecology of, and best conservation practices for, biota on very old, climatically buffered, infertile landscapes (Ocbils). Scope This paper reviews recent multi-disciplinary literature inspired by or reacting to aspects of Ocbil theory and discusses how it can assist conservation in biodiversity hotspots. Conclusions Ocbils occur in at least 12 out of 35 known terrestrial hotspots, but also in other biologically significant sites. Most evidence comes from the Southwest Australian and Greater Cape Floristic Regions, South America's Pantepui, and the Campo Rupestre of Brazil, though predictions of the theory have been corroborated in 22 sites across South America, Western and Eastern Africa, Southern Asia, and Oceania. Most hypotheses have been corroborated, indicating that Ocbil theory has survived largely intact after 6 years of independent scientific critique, quantitative experimentation, and development. The theory also has been extended to allow identification and characterization of OCBISs (old, climatically-buffered, infertile seascapes), and OCFELs (old, climatically-buffered, fertile landscapes). We illustrate that the principles of Ocbil theory are key to conservation of biodiversity at global scale and provide new directions for research that can improve the theoretical and practical contributions of Ocbil theory.

“…Currently there is no estimate of the proportion of endemics of the whole campo rupestre flora, but percentages are thought to be higher than that of lowland cerrado (Hughes et al 2013). Plant communities in canga sustain approximately 6 % of endemics, similar to other mainland metalliferous habitats such as the Katanga (DR Congo) copper belt and the Yilgarn ironstones in western Australia (Gibson et al 2012;Meissner et al 2009;Faucon et al 2010).…”

“…Banded iron formations (BIF) and associated ironstone landscapes are hotspots of plant diversity around the world (Gibson et al 2012, Gledhill 1970, Porembski et al 1994, Valentin et al 1999, Vincent et al 2002, supporting plant communities distinctive, both structurally and floristically from surrounding vegetation (Gibson et al 2010, Jacobi et al 2008, Yates et al 2011a). In Brazil, campo rupestre refers to rupicolous (rocky habitat) vegetation that grows on a range of geologies, including quartzite-sandstone (Harley and Simmons 1986), granite-gneiss (Queiroz et al 1996) and itabirite -an iron-rich metal sedimentary rock (Jacobi and do Carmo 2011, Jacobi et al…”

Vegetation and soil properties of an iron-rich canga (laterite) island on the largest outcrop of banded-iron formation in Serra de Carajás (eastern Amazonia, Brazil) were studied along a topographic gradient (738-762 m asl), and analyzed to test the hypothesis that soil chemical and physical attributes play a key role in the structure and floristic composition of these plant communities. Soil and vegetation were sampled in eight replicate plots within each of the four vegetation types. Surface (0-10 cm) soil samples from each plot were analyzed for basic cations, N, P and plant species density for all species was recorded. CCA ordination analysis showed a strong separation between forest and non-forest sites on the first axis, and between herbaceous and shrubby campo rupestre on the second axis. The four vegetation types shared few plant species, which was attributed to their distinctive soil environments and filtering of their constituent species by chemical, physical and hydrological constraints. Thus, we can infer that Edaphic (pedological) factors are crucial in explaining the types and distributions of campo rupestre vegetation associated with ferruginous ironstone uplands (Canga) in Carajás, eastern Amazonia, therefore the soil properties are the main drivers of vegetation composition and structure on these ironstone islands.
