FIG. 2 in Nest-Site Fidelity and Sex-Biased Dispersal Affect Spatial Genetic Structure of Eastern Box Turtles (Terrapene carolina carolina) at Their Northern Range Edge
FIG. 2. Spatial genetic autocorrelograms of genetic correlation coefficients (r) as a function of distance for Eastern Box Turtles in northwestern Michigan. Plots represent (A) all individuals (n ¼ 165), (B) females only (n ¼ 104), and (C) males only (n ¼ 51). Dashed lines are permuted 95% confidence intervals across all data, and error bars are bootstrapped 95% confidence intervals within each distance class. Tables below graphs represent data for each distance class including the number of pairwise comparisons (n), the correlation coefficients (r), and the P-values (p) associated with bootstrap tests of significance for positive spatial genetic autocorrelation.
FIG. 1 in Nest-Site Fidelity and Sex-Biased Dispersal Affect Spatial Genetic Structure of Eastern Box Turtles (Terrapene carolina carolina) at Their Northern Range Edge
FIG. 1. Scatterplot showing the matrix of pairwise genetic distances and matrix of pairwise geographic distances for box turtles sampled along the river corridor. Warmer colors within the kernel density indicate higher densities of points. The line (slope ¼ 1.074727e–05; R2 ¼ 0.002992) shows the correlation trend.
FIGURE 4. STRUCTURE 2.3.4 in Further examination of the geographic range of Eriogonum corymbosum var. nilesii (Polygonaceae, Eriogoneae)
FIGURE 4. STRUCTURE 2.3.4 bar graph of 14 populations with color-coded assignments to four clusters. The inferred taxonomic assignments (based on predominant color coding) are listed above each population set. Blue corresponds to Eriogonum corymbosum var. nilesii, yellow to E. corymbosum var. aureum, green for E. thompsoniae, and red (the Badlands population) is not clearly associated with the other taxa. Each vertical bar represents an individual, with proportions of the 4 colors in each based on AFLP profiles.

Data from: Social and genetic population structure of free-ranging cheetah in Botswana: implications for conservation
Once widely distributed throughout Africa, cheetahs (Acinonyx jubatus) occur today within fragmented populations and are listed as vulnerable by the IUCN. Botswana currently hosts the second largest cheetah population throughout the species' range. This study initiated a molecular genetic survey of wild Botswana cheetah populations. It focused on the relatedness within presumed social groups using 14 microsatellite markers and revealed a higher proportion of unrelated male coalitions than was expected. Based on the unrelated cheetahs only, the estimation of the genetic variation corresponded with results from recent studies on different African populations. The analysis of unrelated individuals indicated limited genetic differentiation between cheetahs from different regions of Botswana. This suggests that the Botswana cheetah population might represent a unique panmictic population as long as sufficient levels of gene flow are maintained within the distribution range. This baseline information will now be incorporated to develop management strategies and set priorities for cheetah conservation in Botswana.
Data from: Influence of northern limit range on genetic diversity and structure in a widespread North American tree, sugar maple (Acer saccharum Marshall)
Due to climate change, the ranges of many North-American tree species are expected to shift northward. Sugar maple (Acer saccharum Marshall) reaches its northern continuous distributional limit in north-eastern North America at the transition between boreal mixed-wood and temperate deciduous forests. We hypothesized that marginal fragmented northern populations from the boreal mixed-wood would have a distinct pattern of genetic structure and diversity. We analyzed 18 microsatellite loci variation in 23 populations distributed along three latitudinal transects (west, central and east) that encompass the continuous-discontinuous species range. Each transect was divided into two zones, continuous (temperate deciduous) and discontinuous (boreal mixed-wood), based on sugar maple stand abundance. Respective positive and negative relationships were found between the distance of each population to the northern limit (D north), and allelic richness (AR) and population differentiation (FST). These relations were tested for each transect separately; the pattern (discontinuous/continuous) remained significant only for the western transect. structure analysis revealed the presence of four clusters. The most northern populations of each transect were assigned to a distinct group. Asymmetrical gene flow occurred from the southern into the four northernmost populations. Southern populations in Québec may have originated from two different postglacial migration routes. No evidence was found to validate the hypothesis that northern populations were remnants of a larger population that had migrated further north of the species range after the retreat of the ice sheet. The northernmost sugar maple populations possibly originated from long distance dispersal.
