Figure 5. Minimum spanning haplotype network derived from a 658 base-pair cytochrome c oxidase subunit I in Six degrees of separation in barnacles? Assessing genetic variability in the sea-turtle epibiont Stomatolepas elegans (Costa) among turtles, beaches and oceans

Figure 5. Minimum spanning haplotype network derived from a 658 base-pair cytochrome c oxidase subunit I (COI) fragment from 57 Stomatolepas elegans collected from nine different Lepidochelys olivacea nesting on Playa Teopa, Jalisco, Mexico, six S. elegans from Caretta caretta from the western Atlantic, and six S. praegustator from C. caretta from the western Atlantic. Circle sizes are proportional to the frequency of each haplotype, with haplotype 1 being most common. Coloured pie slices are also proportional, and represent the number of S. elegans from each turtle characterized by the respective haplotype. Colours represent the nine Mexican turtles randomly sampled for S. elegans populations. Open circles with numbers indicate Atlantic haplotypes. Solid black circles designate hypothetical missing haplotypes. The network includes S. elegans haplotypes 1–21, and S. praegustator haplotypes 19, 26–30. Haplotypes 1–17, shown in colour, represent Jalisco, Mexico specimens collected from nine different turtles in the Pacific, and haplotypes 18–21 and 26–30, shown as unshaded circles, represent southeastern United States Atlantic specimens collected from six different C. caretta (see Table 1).

FIGURE 12 in Vulcanolepas scotiaensis sp. nov., a new deep-sea scalpelliform barnacle (Eolepadidae: Neolepadinae) from hydrothermal vents in the Scotia Sea, Antarctica

FIGURE 12. Benthic Ecology: The V. scotiaensis sp. nov. assemblage at the "Dog's Head" vent in E2. The morphotype present here is predominantly the 'robust' variety of V. scotiaensis sp. nov., and specimens are generally heavily encrusted with blackish Fe/Mn minerals. The greatest density of organisms is found along what is interpreted as an old, or dying active vent. The bio-density in this reduced energy environment is significantly lower than at "Carwash" (Figure 11).

FIGURE 10a in Vulcanolepas scotiaensis sp. nov., a new deep-sea scalpelliform barnacle (Eolepadidae: Neolepadinae) from hydrothermal vents in the Scotia Sea, Antarctica

FIGURE 10a. Ratios of peduncle to capitulum length. The "gracile" form (shown as series 1, a diamond) is the less ornamented variety, and by far the most abundant in the collections. During growth, the peduncle can grow up to 20 times the length of the capitulum. The trend line included is for the "gracile" form only; the R2 correlation of this regression at 0.72518 confirms a reasonable correlation—i.e. that with growth, the pedun11 cle can be expected to become proportionately longer. However, the "robust" variety (shown here as series 2, a square) has subequal p:c ratios, and this apparently changes little with growth (= age), such that some larger specimens may even possess a capitulum that is slightly longer than the peduncle. This part of the graph is isolated and used in Figure 10b. Data base 57 specimens ("gracile" from JC42 F-0396 (34), JC42 F386 (10); "robust" 13 from JC42-F0122). p = peduncle length, c = capitulum length.
