“…Several types of underground systems are responsible for more than 50% of the plant biomass in the CRs. These bud banks are an adaptation to disturbance (Klimes˘ová and Klimeš, 2007) represented in the CRs by savanna fires and the arid season (Conceição and Pirani, 2005;Kolbek and Alves, 2008), and sometimes can guarantee an impressive longevity for some species (Alves et al, 2013).…”

Circumscribing campo rupestre – megadiverse Brazilian rocky montane savanas

Currently campo rupestre (CR) is a name accepted and used internationally by botanists, zoologists, and other naturalists, usually applied to a very specific ecosystem, despite the lack of a consensual published circumscription. We present a tentative geographic circumscription of the term, combining data on climate, geology, geomorphology, soil, flora, fauna and vegetation. The circumscription of campo rupestre proposed herein is based on the following premises:(1) the classification of vegetation is not an exact science, and it is difficult to attain a high degree of consensus to the circumscription of vegetation names; (2) despite this, vegetation classification is useful for conservation and management. It is thus desirable to circumscribe vegetation types with the greatest attainable precision; (3) there is a need to preserve all montane and rocky vegetation types, regardless of classification, biome, etc; (4) the CRs are formed by a complex mosaic of vegetation types including rock-dwelling, psammophilous, aquatic, epiphytic, and penumbral plant communities. Campos rupestres stricto sensu are a Neotropical, azonal vegetation complex endemic to Brazil, forming a mosaic of rocky mountaintop "archipelagos" inserted within a matrix of zonal vegetation, mainly in the Cerrado and Caatinga provinces of the Brazilian Shield (southeastern, northeastern and central-western regions), occurring mainly above 900 m asl. up to altitudes exceeding 2000 m, having measured annual precipitation between 800 and 1500 mm, and an arid season of two to five months.Keywords: rocky savana, montane savana, rock-dwelling vegetation, biogeographic elements, vegetation classification, Neotropics. Circunscrevendo campo rupestre -savanas montanas rochosas megadiversas do Brasil ResumoAtualmente campo rupestre (CR) é um termo aceito e internacionalmente usado por botânicos, zoólogos e outros naturalistas, geralmente aplicado a um ecossistema muito específico apesar de não haver uma circunscrição de consenso. Nós apresentamos uma ciscunscrição geográfica tentativa do termo, combinando dados de clima, geologia, geomorfologia, solo, flora, fauna e vegetação. A circunscrição de campo rupestre aqui proposta se baseia nas seguintes premissas: (1) a classificação da vegetação não é uma ciência exata e é difícil atingir um alto grau de consenso sobre a circunscrição de nomes de vegetação; (2) apesar disto, a classificação da vegetação é útil para conservação e manejo. Assim é desejável descrever os tipos de vegetação com a maior precisão tangível; exista a necessidade de se preservar todos os tipos de vegetação montanos e rochosos, independentemente de sua classificação, bioma, etc. (4) os CRs são formados por um complexo mosaico de tipos de vegetação incluindo comunidades sobre rocha, psamíóilas, aquáticas, epífitas e penumbrais. Os campos rupestres stricto sensu são um complexo de vegetação endêmico ao Brasil, azonal, Neotropical, inserido numa matriz de vegetação zonal, sobretudo nas províncias do Cerrado e da Caatinga do Escudo do Bra...

“…Clonality and long-lived individuals have been documented in a few studies, mostly of plants (Alves et al 2013;Neves et al 2014). Long-lived marine fish from the coastline of the SWAFR (Molony et al 2011) provide a novel case paralleling the long-lived terrestrial organisms dominating some Ocbils.…”

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.

“…This strategy may contribute to individual longevity. Estimated age of the oldest individuals of Vellozia kolbekii is 551 years (Alves 1994), and 3801 years for Jacaranda decurrens (Bignoniaceae), one of the oldest known living Neotropical plants (Alves et al 2013). …”
