F I G U R E 2 in Phylogeography of Solomon Islands blossom bats reflects oceanic divides and Pleistocene connections

F I G U R E 2 Phylogeographic relationships among Melonycterini blossom bats (a) the Solomon Islands archipelago with bathymetric depths less than 120 m (ETOPO1, Amante & Eakins, 2009) shaded in dark grey to indicate possible land bridge connections during the Last Glacial Maximum. Islands shaded in colour represent those sampled for this study, samples were unavailable for islands shaded in light grey (EPSG: 4326–WGS 84). (b) Phylogenetic tree made using maximum likelihood methods in RAXML depicting relationships among all Nesonycteris and Melonycteris samples. Values indicate maximum likelihood bootstrap support and black circles on nodes denote values = 100. (c) Representation of the taxonomic treatment of Nesonycteris prior to this study comprising two species; (d) Alternate taxonomic treatment of Nesonycteris from the results of this study comprising four species (N. far = N. fardoulisi, N. mac = N. maccoyi); The results of STRUCTURE analyses for various datasets are presented as (e) Dataset 1, a single run, k = 4; (f) Dataset 2, a single run, k = 2; (g) Dataset 3, a single run, k = 3; and (h) Dataset 4 (five runs R1–R5, k = 4). In STRUCTURE results (e–h), each bar indicates the probability of assignment to different genetic clusters.
