Figure 3 in Isolation by geographical distance after release from Pleistocene refugia explains genetic and phenotypic variation in Xylotrupes siamensis (Coleoptera: Scarabaeidae)
Figure 3. Phylogenetic networks of the three analysed loci and three historical scenarios explaining the origin of the CLAOS population tested using the DIYABC program. The colour of each individual shown in the network corresponds to the taxonomic assignment colour in the DIYABC analysis. Scenario 2 was the most likely model selected by the program (~60% posterior support), and scenario 1 also received moderate support (~30% posterior support). Results of posterior support among scenarios and model checking, in addition to the estimated parameter values (population sizes and divergence times), can be found in the Supporting Information (Figs S3–S8).
Figure 1 in Isolation by geographical distance after release from Pleistocene refugia explains genetic and phenotypic variation in Xylotrupes siamensis (Coleoptera: Scarabaeidae)
Figure 1. Different male horn phenotypes in Xylotrupes siamensis. Left panels show exemplars of males of the Tonkinensis (short horn) phenotypes and right panels the Siamensis (long horn with a cephalic horn denticle) phenotype. Samples from the CLAOS population (for details, see Table 1; Fig. 2) exhibit intermediate horn length, and the major males have the cephalic horn denticle.
Figure 4 in Isolation by geographical distance after release from Pleistocene refugia explains genetic and phenotypic variation in Xylotrupes siamensis (Coleoptera: Scarabaeidae)
Figure 4. Associations between three biogeographical distance measures and genetic differentiation (FST), measured at three loci (CO1, ITS2 and H3), for populations of Xylotrupes siamensis. Mantel test statistics (r) indicate the strength and significance of correlations between the genetic distance and biogeographical distance. Distance calculations are detailed in the Material and Methods section. Least cost distances were subject to rescaling and are thus unitless.
Figure 2. A in Isolation by geographical distance after release from Pleistocene refugia explains genetic and phenotypic variation in Xylotrupes siamensis (Coleoptera: Scarabaeidae)
Figure 2. A, the sampling sites of Xylotrupes siamensis populations in this study. White circles indicate samples of the Tonkinensis form and grey circles the Siamensis form. The Mekong River is indicated using a thick grey line; elevational differences are shown via a coloured scale, where a lighter colour depicts higher elevation (maximum = 4000 m a.s.l.). B, location of the study area within the Asia–Pacific region. C–E, species distribution model predictions based on the Last Interglacial (C), the Last Glacial Maximum (D) and current climatic conditions (E) are shown, where darker blue indicates higher predicted climatic suitability.
An evaluation of isolation by distance (IBD) and isolation by resistance (IBR) on genetic structure of the Persian squirrel (Sciurus anomalus) in the Zagros forests of Iran
<p>For conservation of wild species, it is important to understand how landscape change and land management can affect gene flow and movement. Landscape genetic analyses provide a powerful approach to infer effects of various landscape factors on gene flow, thereby informing conservation actions. The Persian squirrel is a keystone species in the woodlands and oak forests of Western Asia, where it has experienced recent habitat loss and fragmentation. We conducted landscape genetic analyses of individuals sampled in the northern Zagros Mountains of Iran (provinces of Kurdistan, Kermanshah, and Ilam), focusing on evaluation of isolation by distance (IBD) and isolation by resistance (IBR), using 16 microsatellite markers. The roles of geographical distance and landscape features including roads, rivers, developed areas, farming and agriculture, forests, lakes, plantation forests, rangelands, shrublands and rocky areas of varying canopy cover, and swamp margins on genetic structure were quantified using individual-based approaches and resistance surface modelling. We found a significant pattern of IBD but only weak support for an effect of forest cover on genetic structure and gene flow. It seems that geographical distance is an important factor limiting the dispersal of the Persian squirrel in this region. The results of the current study inform ongoing conservation programs for the Persian squirrel in the Zagros oak forest.</p>
