Composição florística de angiospermas no carste do Alto São Francisco, Minas Gerais, Brasil

Abstract: A ocorrência de rochas carbonáticas delimita um tipo particular de relevo, o carste, o qual, pela geomorfologia e hidrologia específicas, difere das paisagens dominantes. Na região cárstica do Alto São Francisco, conhecida como "Mata de Pains", encontram-se exemplos marcantes de relevos cársticos ocorrentes em Minas Gerais. No cárste, a cobertura vegetal é composta por mosaico fitofisionômico apresentando áreas florestadas e áreas abertas, com notável diversidade florística. O objetivo deste estudo foi realiza… Show more

“…As for the second factor, an analysis of each sampled location indicates that the species composition is associated with the phytogeographic domain where it is located or with the regional flora. Three cases exemplify this well: (a) the greatest diversity of Pleurothallidinae and Maxillariinae is found in karsts associated with the Atlantic Forest; (b) the occurrence of species and genera typical of the Atlantic Forest in Mata de Pains (Melo et al 2013), located within the Cerrado domain, but in a transitional region with the Atlantic Forest; and (c) the distribution of species in the Cyrtopodium andersonii species complex (Batista & Bianchetti 2020), which is conditioned by the domain. Cyrtopodium glutiniferum occurs in karsts of the Atlantic Forest and bordering regions with the Cerrado (SE Brazil), C. withneri in karsts in the core region of the Cerrado (WC Brazil), and C. andersonii in the Amazon (N South America and N Brazil).…”

“…To evaluate the diversity of Orchidaceae associated with karsts in Brazil, we used the datasets of speciesLink (2021), Herbário Virtual Reflora (Flora e Funga do Brasil 2021), and the main floristic studies with records of Orchidaceae in karsts of Brazil (Warming 1908;Bianchetti et al 2005;Melo 2008;Melo et al 2013;Peixoto 2018;Ferreira & Stehmann 2020). For the dataset searches, we filtered Orchidaceae collections using the following keywords associated with karst: 'calcário(a)', 'calcáreo(a)', 'limestone ', 'carst', 'carste', 'karst', and 'cárstico(a)'.…”

“…Inventários fitossociológicos são importantes, pois fornecem o histórico de como as plantas se organizam no espaço podendo ser utilizados para o planejamento de políticas de conservação (MELO et al, 2013). Isso reforça a necessidade do aumento do número de estudos em afloramentos rochosos que proponham políticas de manejo para o ecossistema, fornecendo subsídios para conservação das espécies (SILVA, 2016).…”
