Geographic distribution patterns of species of the subtribe Lychnophorinae (Asteraceae: Vernonieae)

Abstract With 119 species distributed in 19 genera, most of the subtribe Lychnophorinae are endemic to Espinhaço Range central eastern Brazil. This region is characterized especially by campos rupestres, a grassland mosaic associated with vegetation on rock outcrops, which display high level endemism. The present work aims identify distribution patterns, collection density, richness and research bias collections. Ten geographic patterns were identified: Chapada Diamantina, dos Veadeiros adjacent mountains, Pico da Aliança, Extension Range, Central-South Arc Minas Gerais, Brasília Arc, Campos Rupestres Restinga, Diamantina Caatinga, Northwest-Southeast Diagonal East Triangle. Other Angiosperm families similar distribution, mainly Meridional, where higher collecting efforts present. Species sites intensity, however, northeast Goiás shows opposite pattern. Spearman correlation analysis strong between density richness, an exponential asymptotic model that quite significant for total variation richness. cluster presented five clusters correlated Lychnophorinae.
