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.
