FIGURE 5 in Genetic and phenotypic diversity of Branchinecta sandiegonensis (Crustacea: Anostraca) in the vernal pools of Baja California, México

FIGURE 5. Plots of effective size trends through time generated by Vareff. The x-axis represents time to the past expressed as the product of the generation time (T) by the mutation rate. The y-axis represents the effective size expressed as the log10 of theta, where theta = 4Neu. For abbreviations, see Fig. 1.

FIGURE 3. a in Genetic and phenotypic diversity of Branchinecta sandiegonensis (Crustacea: Anostraca) in the vernal pools of Baja California, México

FIGURE 3. a, Bayesian phylogenetic tree of B. sandiegonensis based on analysis of mitochondrial COI sequences, showing the two major clades: Clade A and Clade B (sensu Bohonak 2005). The 31 samples obtained in this study are denoted by rectangles, with colors corresponding to the region of collection. The 54 sequences downloaded from GenBank lack colored rectangles, and all are from the northern portion of the species' range in the USA (GenBank accession numbers: FJ439689-FJ439743). The tree was rooted with Branchinecta lynchi (GenBank accession numbers HM568501-HM568505). Numbers on branches indicate Bayesian posterior probabilities ≥0.8. b, Median-joining haplotype network based on 568 bp of the mitochondrial COI sequences. Circle size is proportional to haplotype frequencies; line length is roughly proportional to the estimated number of steps between haplotypes. Each geographic region is represented in a different color. For abbreviations, see Fig. 1.

Drawing modified from Fugate (1993) and morphometric features based on Timms (2012). a, total body length. b, thorax length. c, abdomen length. d, cercopod length. e, antennule length. f, right antenna length for males, and f1 for females.

FIGURE 4. a, Principal components analysis of the individual genotypes, where the region was used as class factor for the analysis. Colors correspond to the region. b, Edwards genetic distance Dendrogram. The colors below names correspond to the region. c, plots of the genetic clusters inferred by STRUCTURE (K=2, 3, 4). Each vertical column represented an individual, and pools are indicated by the legend. For abbreviations, see Fig. 1.
