植物学家、生态学家和进化生物学家都熟悉开普植物区（Cape Floristic Region）令人惊讶的物种丰富性和特有性，以及澳大利亚西南部kwongkan地区古老而独特的植物群。这些地区代表了古老的气候缓冲贫瘠景观（OCBILs），这是解释其丰富性和特有性的一般假设的基础。然而，很少有生态学家熟悉巴西中部和东部的campo rupestre，这是一个非常古老的山顶生态系统，既是古老谱系的博物馆，也是地方性谱系持续多样化的摇篮。一些谱系的campo rupestre的多样化早于低地cerrado的多样化，这表明它可能是南美洲东部最古老的开放植被。该植被包括超过5000种植物，占巴西植物多样性的近15%，面积相当于其表面的0.78%。回顾经验数据，我们仔细检查五个预测的OCBIL理论，并表明，坎波鲁佩斯特是完全可比的，显着收敛与fynbos和kwongkan，并满足标准的经典OCBIL。日益增加的威胁，以坎波rupestre正在损害生态系统服务，我们主张实施更有效的保护和恢复战略。
Botanists, ecologists and evolutionary biologists are familiar with the astonishing species richness and endemism of the fynbos of the Cape Floristic Region and the ancient and unique flora of the kwongkan of south-western Australia. These regions represent old climatically-buffered infertile landscapes (OCBILs) that are the basis of a general hypothesis to explain their richness and endemism. However, few ecologists are familiar with the campo rupestre of central and eastern Brazil, an extremely old mountaintop ecosystem that is both a museum of ancient lineages and a cradle of continuing diversification of endemic lineages. Diversification of some lineages of campo rupestre pre-dates diversification of lowland cerrado, suggesting it may be the most ancient open vegetation in eastern South America. This vegetation comprises more than 5000 plant species, nearly 15 % of Brazil’s plant diversity, in an area corresponding to 0.78 % of its surface. Reviewing empirical data, we scrutinise five predictions of the OCBIL theory, and show that campo rupestre is fully comparable to and remarkably convergent with both fynbos and kwongkan, and fulfills the criteria for a classic OCBIL. The increasing threats to campo rupestre are compromising ecosystem services and we argue for the implementation of more effective conservation and restoration strategies.
