FIGURE 5 in Laminatubus (Serpulidae, Annelida) from eastern Pacific hydrothermal vents and methane seeps, with description of two new species
FIGURE 5. Plot using ABGD (Puillandre et al. 2012) of pairwise distances across all Laminatubus joycebrooksae n. sp. and L. paulbrooksi n. sp. CytB sequences using the Kimura (K80) model. There is a clear 'barcode' gap between L. joycebrooksae n. sp. and L. paulbrooksi n. sp. with the latter taxon showing a high level of intraspecific variation. Uncorrected pairwise distances gave a similar distribution.
FIGURE 4. Combined haplotype networks from CytB data for Laminatubus paulbrooksi n in Laminatubus (Serpulidae, Annelida) from eastern Pacific hydrothermal vents and methane seeps, with description of two new species
FIGURE 4. Combined haplotype networks from CytB data for Laminatubus paulbrooksi n. sp. (top) from Pacific Costa Rica margin and Gulf of California (Mexico) localities and L. joycebrooksae n. sp. (bottom) from Costa Rica. There was little variability among the L. joycebrooksae n. sp. sequences and a distinct break to L. paulbrooksi n. sp. This corresponds to a minimum 6.4% uncorrected distance. Laminatubus paulbrooksi n. sp. showed marked intraspecific variability with distinct breaks among the three main sites; Costa Rica (9°N), Pescadero (23°N) and Guaymas Basin (27°N). * indicates the holotypes for L. paulbrooksi n. sp. and L. joycebrooksae n. sp. respectively.

Concentrations of dissolved gases at a methane seep in the deep northern Gulf of Mexico measured with an in situ mass spectrometer (ISMS)
<p>Concentrations of dissolved methane, hydrogen sulfide, carbon dioxide and oxygen in a <em>Bathymodiolus</em> mussel bed at a methane seep in the deep northern Gulf of Mexico. The data were collected with an in situ mass spectrometer (ISMS) on May 6, 2015, during a research cruise with RV Nautilus, dive H1423. The location was site MC853, at 28.12835 (lat), -89.14100 (long), in 1080 m water depth. At this site the two mussel species <em>Bathymodiolus brooksi</em> and <em>B. childressi</em> were collected. ISMS measurements were performed before and after the removal of animals from the mussel bed.</p>
