Fig. 7 in A new Pipistrelle bat from the oceanic Island of Príncipe (Western Central Africa)
Fig. 7.—Selected echolocation calls of Pseudoromicia principis sp. nov. with three examples (A, B, C) of calls showing decreasing frequency modulation (FM) and increasing quasi-constant frequency (QCF) elements. Calls were directly recorded from free-flying bats at dusk in Santo António city and surroundings.

Fig. 3.—Portrait of Pseudoromicia principis sp. nov. showing a typical pipistrelle-like appearance. Pelage is chocolate brown dorsally and ventrally although tips of the ventral pelage present a distinct light creamy tinge. Photograph by Jorge Palmeirim.

Fig. 2.—Bayesian phylogenetic reconstruction based on the mitochondrial gene cytochrome b (Cytb). Values above branches represent Bayesian posterior probabilities and values below branches are bootstrap values of maximum likelihood (support values <50 are not shown). The right column presents sequences GenBank accession numbers. The sequence JQ956446 is listed in GenBank as Pseudoromicia tenuipinnis but it was probably misidentified. See Table 1 for a complete list of the specimens used and main text for details of the molecular analyses.

Diversification of the orchid genus Tridactyle: origin of endemism on the oceanic islands of São Tomé & Príncipe in the Gulf of Guinea
<p><b>Aim</b>: Oceanic islands have played an important role in our understanding of the diversification of organisms, and phylogenetic estimates have been used in this context to investigate the origin of island diversity and its relationship to the continent. Using a typical orchid genus rich in island endemics and with widespread continental relatives, we aim to compare alternative hypotheses of diversification with a focus on island endemism.</p> <p><b>Location</b>: Tropical Africa and the Gulf of Guinea Islands of São Tomé & Príncipe, Central Africa.</p> <p><b>Taxon:</b> <i>Tridactyle</i> genus (Orchidaceae).</p> <p><b>Methods</b>: We used genome skimming to sequence the whole chloroplast genome and nuclear ribosomal genes from 157 individuals of 34 <i>Tridactyle</i> species and 15 individuals of 12 other orchid genera (outgroups) to infer a time-calibrated phylogenetic tree of the genus <i>Tridactyle</i>. We also used multiple statistical methods to infer the geographic ranges of the ancestral nodes from the estimated phylogeny. Alternative hypotheses for the origins of endemism on the islands of São Tomé and Príncipe were investigated based on the biogeographic reconstruction of the genus.</p> <p><b>Results</b>: The estimated phylogeny of <i>Tridactyle</i> and reconstruction of geographic ranges for the ancestral nodes suggested a general history of allopatric speciation for the genus, in particular via colonisation of the islands of the Gulf of Guinea that induced a long period of geographic isolation. The most parsimonious hypothesis to explain island endemism in <i>Tridactyle</i> involved 6 independent colonisations of the islands from the continent.</p> <p><b>Main conclusions: </b>In contrast to other cases of oceanic island endemism that involved adaptive radiation on an island or within an archipelago, endemism in <i>Tridactyle</i> is better explained by multiple colonisation events from the continent to São Tomé and Príncipe, with subsequent divergences due to geographic isolation but only one potential instance of further diversification on the islands.</p>
