Fig. 1From: Clade-age-dependent diversification under high species turnover shapes species richness disparities among tropical rainforest lineages of Bulbophyllum (Orchidaceae)Distribution of the pantropical orchid genus Bulbophyllum across the four major tropical rainforest (TRF) regions. a Distribution of tropical rainforests sensu lato (tropical and subtropical moist broadleaf forest) based on Olsen and Dinerstein [3] as freely available from The Nature Conservancy website (http://maps.tnc.org). b Extant occurrence points (dots) of the genus in the Neotropics (red), Africa (black), Madagascar (blue) and the Asia-Pacific region (orange), based on GBIF geo-referenced specimens and additional records taken from the literature and herbarium collections (see text).
