Figure 1. Localities of Trachymyrmex septentrionalisspecimen sampling sites in this study, color-coded by major region. The Apalachicola National Forest is highlighted in green. Major cities are denoted by gray stars and major rivers are labeled.
Figure 2. Bayesian model-based genetic clusters (K = 2) inferred from STRUCTURE analyses using nine microsatellite loci from 64Trachymyrmex septentrionalis ants across Florida. Each vertical bar represents an individual and each section between black bars represents major regions, which are labeled above. The two colors represent the two unique genetic clusters, and the proportion of each color represents the assignment probability of that individual to each cluster.
Figure 3. Isolation by distance scatterplots showing the relationship between genetic differentiation (transformed pairwise Fst values) and geographic distance (distance between sites in km) as identified by Mantel tests for Trachymyrmex septentrionalis ants in Florida. The analyses were conducted across (A) all sampling sites across all regions, (B) all sampling sites excluding SGI, (C) all sampling sites within the ANF only, and (D) all sampling sites within the peninsula only. Regression coefficients and p-values are displayed for each analysis.
Figure 4. A TCS haplotype network for Trachymyrmex septentrionalis constructed with COI mitochondrial DNA sequences. Each circle represents a unique haplotype and the relative size of circles is proportional to the number of individuals harboring that haplotype. Colors correspond to sampling sites and align with Figure 1. Tick marks on branches indicate the number of mutations between haplotypes. Small black circles represent predicted intermediate haplotypes. Haplotype clades (Ts Clades I-III) are circled, highlighted, and labeled.
