Data from" Euphotic Zone Metabolism in the North Pacific Subtropical Gyre Based on Oxygen Dynamics"
<p>This data set provides measurements of oxygen to argon molar ratios from discrete samples collected within the mixed layer at the long-term sampling site (Station ALOHA) of the Hawaii Ocean Time-Series program, within the North Pacific Subtropical Gyre, between November 2013 and January 2019 (near-monthly cruises). Samples were measured by membrane inlet mass spectrometry following Ferrón et al. (2015). Version 2 had corrected longitude data (in decimal degrees east). Version 3 includes a new file with estimated rates of net community production, gross oxygen production and community respiration for the mixed layer.</p>

Fig. A4 in Susceptibility of tropical mountain forests to biological invasions from the temperate and subtropical zone, exemplified by Zonitoides (Gastropoda: Gastrodontidae)
Fig. A4. Global climatic suitability for: (a) Zonitoides arboreus s.l.; and (b) Zonitoides nitidus based on Mahalanobis distances using the 20 km grid resolution. The higher the threshold, the more dissimilar are the climatic conditions to those of the majority of known occurrences, and>100% means that the climatic conditions are dissimilar to those of any other available record. Please note that the deserts of Africa, Arabia and Australia are unlikely places for a snail that inhabits (temperate) forests in its native range (Z. arboreus s.l.), and that the Great Lakes Region that seems well inhabited by Z. nitidus does not fully match its climate, what can only be explained from effects of averaging local climates at a larger grid scale.

Fig. 1 in Susceptibility of tropical mountain forests to biological invasions from the temperate and subtropical zone, exemplified by Zonitoides (Gastropoda: Gastrodontidae)
Fig. 1. Estimation of the phylogenetic relationships of the COI barcoding sequence from the Zonitoides specimens and two outgroups (labeled with their BOLD or GenBank accession numbers) using the Maximum Likelihood method based on the Tamura-Nei model. The tree with the highest log likelihood (−2138.3583) is shown. Branch lengths equal genetic distances in terms of the number of base substitutions per site. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (500 replicates) are shown next to the branches. The tree was constructed in MEGA 6.0. Please note that the shell of (living) Z. nitidus is darkly pigmented, and that the extended animal of the depicted Z. nitidus started fading.

Data from: Vertical gradients in species richness and community composition across the twilight zone in the North Pacific Subtropical Gyre
Although metazoan animals in the mesopelagic zone play critical roles in deep pelagic food webs and in the attenuation of carbon in midwaters, the diversity of these assemblages is not fully known. A metabarcoding survey of mesozooplankton diversity across the epipelagic, mesopelagic and upper bathypelagic zones (0-1500m) in the North Pacific Subtropical Gyre revealed far higher estimates of species richness than expected given prior morphology-based studies in the region (4,024 OTUs, 10-fold increase), despite conservative bioinformatic processing. OTU richness of the full assemblage peaked at lower epipelagic-upper mesopelagic depths (100-300m), with slight shoaling of maximal richness at night due to diel vertical migration, in contrast to expectations of a deep mesopelagic diversity maximum as reported for several plankton groups in early systematic and zoogeographic studies. Four distinct depth-stratified species assemblages were identified, with faunal transitions occurring at 100m, 300m, and 500m. Highest diversity occurred in the smallest zooplankton size fractions (0.2-0.5mm), which had significantly lower % OTUs classified due to poor representation in reference databases, suggesting a deep reservoir of poorly understood diversity in the smallest metazoan animals. A diverse meroplankton assemblage also was detected (350 OTUs), including larvae of both shallow and deep living benthic species. Our results provide some of the first insights into the hidden diversity present in zooplankton assemblages in midwaters, and a molecular reappraisal of vertical gradients in species richness, depth distributions, and community composition for the full zooplankton assemblage across the epipelagic, mesopelagic and upper bathypelagic zones.
