“…Conservation strategies and the choice of priority areas are usually based on the presence of red-listed endangered species, but abundance, persistence, geographic distribution, and level of threats should also be quantified (Kakkala & Moinen, 2013;Nakajima, Junqueira, Freitas, & Teles, 2012). Campo rupestre lineages show high phylogenetic conservatism and low dispersal and colonization capabilities and are thus highly deserving of conservation priority (Conceic¸ão et al, 2016).…”

Brazilian rupestrian grasslands (campos rupestres) are old, climatically buffered infertile landscapes, which support many endemic species. Asteraceae show the high levels of plant endemism and contain more endangered species than any other family in Brazil. Here, we evaluated the complementarity of two protected areas for the conservation of endangered Asteraceae along the Espinhaço Mountain range, Southeast Brazil. Specifically, we investigated if the known endangered Asteraceae flora of the Diamantina District Plateau (38 species) occurs in two protected areas, Rio Preto State Park and Sempre Vivas National Park, and if these areas are complimentary or overlapping in protecting endangered Asteraceae species. To survey Asteraceae, we used a standardized RAPELD protocol (21 1 ha plots) and traditional floristic collecting (117 ha polygon/32 days/average team ¼ 2.1 collectors) across different habitats and altitudes within both areas. RAPELD protocol recorded 115 species in a sample of 12,775 individuals of Asteraceae. Traditional floristic collecting recorded 172 species in a sample of 613 collections. Seventy-nine percent of endangered species known to occur within the Plateau were recollected by either RAPELD or traditional floristic collecting. Only 13% of endangered Asteraceae flora was common to both protected areas; 47% occur in Rio Preto State Park and 34% in Sempre Vivas National Park; combined, they recorded 68% of the endangered Plateau Asteraceae flora; only one critically endangered species was recorded. The two parks are complimentary but insufficient to protect the endangered Asteraceae flora of the Plateau; the uneven distribution of endangered species in the Diamantina District Plateau is a threat to their conservation.

“…Finalmente, o Cerrado e o Estado de Minas Gerais possuem os maiores números de espécies de Asteraceae ameaçadas de extinção do Brasil (Nakajima et al 2012b). Para que haja sua conservação, devem continuar a ser realizados trabalhos de inventários florísticos, para complementação das informações sobre as espécies pouco conhecidas, proporcionando assim bases científicas para a conservação das áreas ameaçadas.…”

-(Heliantheae s.l. (Asteraceae) from Parque Estadual do Biribiri, Diamantina, Minas Gerais State, Brazil). Heliantheae s.l., the third largest tribe in the Asteraceae family, has 48 genera and 379 species in Brazil, with 199 species restricted to this country. The tribe is very representative of Espinhaço Range flora, which presents a great diversity and endemism. This work presents the taxonomic treatment of Heliantheae s.l. of Parque Estadual do Biribiri (PEB), located in the Espinhaço Range, Diamantina municipality, Minas Gerais State. It provides an identification key, morphological description, geographic distribution, and taxonomic commentaries for each species. The tribe Heliantheae s.l. in PEB has nine genera and 16 species: Acanthospermum, Aldama, Cosmos, Dimerostemma, Galinsoga, and Melampodium (one species each); Aspilia and Bidens (three spp. each), and Calea (four spp.). The PEB has a great number of species Heliantheae s.l. compared with other areas of Minas Gerais State, and it has 12.5% of its species restricted to Minas Gerais State, revealing the importance of this park to protect the flora of Espinhaço Range.

“…O Cerrado é o domínio fitogeográfico brasileiro que concentra o maior número de espécies de Asteraceae ameaçadas de extinção, uma vez que esta família é muito frequente neste domínio, que tem sofrido forte pressão antrópica (Nakajima et al 2012). Os Campos Rupestres que ocorrem no Cerrado destacam-se com um elevado número de espécies endêmicas, em especial de Asteraceae (Giulietti et al 2005;Nakajima et al 2012;Ribeiro et al 2008).…”

ResumoEste trabalho consiste no levantamento florístico de Asteraceae nos Campos Rupestres das Serras da Bocaina e de Carrancas que estão localizadas no Planalto Alto Rio Grande, no sul de Minas Gerais, bem como uma análise de similaridade florística com outras áreas serranas do Planalto Brasileiro. O levantamento florístico foi realizado em 11 áreas localizadas nas Serras da Bocaina e de Carrancas. A similaridade florística foi realizada entre outras 17 áreas de Campos de Minas Gerais, São Paulo, Rio de Janeiro e Bahia. Neste levantamento florístico, a família apresentou 117 espécies, distribuídas em 43 gêneros pertencentes a 14 tribos. Os gêneros que têm maior riqueza de espécies são Baccharis (14), Lessingianthus (10), Mikania (8) e Chromolaena (8). As Serras da Bocaina e de Carrancas apresentaram maior similaridade florística com a Serra da Canastra, Serra de São José e Toca dos Urubus, enquanto a menor similaridade apresentada foi com a Serra dos Órgãos. Não houve correlação significativa em relação à similaridade florística e a distância geográfica entre as áreas analisadas. As relações na composição florística entre os grupos formados provavelmente estão relacionadas com aspectos geomorfológicos, edáficos, climáticos, além da influência vegetacional dos domínios fitogeográficos onde estes campos estão inseridos. Palavras-chave: Cerrado, afloramento rochoso, espécies endêmicas, similaridade florística AbstractThis work reports on a floristic survey of Asteraceae in rocky outcrop grasslands on the Bocaina and Carrancas mountain range, located in the Upper Rio Grande highlands, southern Minas Gerais State, as well as on an analysis of floristic similarity between mountainous areas of Brazilian Plateau. The floristic survey was carried out in 11 areas on the Bocaina and Carrancas mountain range. The floristic similarity was carried out between 17 other grasslands of Minas Gerais, São Paulo, Rio de Janeiro and Bahia. In this floristic survey, the family showed 117 species, 43 genera and 14 tribes. The richest genera were Baccharis (14), Lessingianthus (10), Mikania (8) and Chromolaena (8). The mountain range of Bocaina and Carrancas showed highest floristic similarity with the mountain range of Canastra, mountain range of São José and Toca dos Urubus, while the lowest similarity were with the mountain range of Órgãos. There was no significant correlation in relation to floristic similarity and geographical distance between the areas analyzed. The relationships in floristic composition between the groups formed are probably related to geomorphological, edaphic, climatic, vegetation beyond the influence of phytogeographic domains where these grasslands are located.
