Cosmopolitanism of microbial eukaryotes in the global deep seas

Deep sea environments cover more than 65% of the earth’s surface and fulfil a range of ecosystem functions, yet they are also amongst the least known habitats on earth. Whilst the discovery of key geological processes, combined with technological developments, has focused interest onto geologically active areas such as hydrothermal vents, most abyssal biodiversity remains to be discovered ( Danovaro et al. 2010 ). However, as for terrestrial reservoirs of biodiversity, the world’s largest biome is under threat from anthropogenic activities ranging from environmental change to the exploitation of minerals and rare‐earth elements ( Kato et al. 2011 ). It is therefore important to understand the magnitude, nature and composition of deep sea biological communities to inform us of levels of local adaptation, functionality and resilience with respect to future environmental perturbation. In this issue of Molecular Ecology, Bik et al. utilize 454 Roche metagenetic environmental sequencing to assess microbial metazoan community composition and phylogenetic identity across deep sea depth gradients and between ocean basins. The analyses suggest that although the majority of microbial eukaryotic taxa are regionally restricted, a small percentage might maintain cosmopolitan deep sea distributions, and an even smaller fraction appear to be eurybathic (live across depth gradients).     

Implications of the UNCLOS Marine Scientific Research Regime for the Current Negotiations on Access and Benefit Sharing of Marine Genetic Resources in Areas Beyond National Jurisdiction

Abstract

Access to marine genetic resources (MGRs) in areas beyond national jurisdiction (ABNJ) and the sharing of benefits arising out of the utilization of these resources are among the most contentious at the UN Intergovernmental Conference on Marine Biodiversity of Areas Beyond National Jurisdiction. This article examines the applicability of the marine scientific research (MSR) regime of the UN Convention on the Law of the Sea (UNCLOS) to the access and benefit-sharing issues. It concludes that the MSR regime of UNCLOS provides the legal basis for setting up nonmonetary-benefit sharing obligations, including the dissemination of information, data, and research results concerning MGRs at the UN negotiations on marine biodiversity in the ABNJ.     

Biodiversity and historical biogeography of stalked crinoids (Echinodermata) in the deep sea

About 95 species of stalked crinoids are now described from 60m to hadal depths, but our knowledge remains far from complete. Depending on which species concept is used, estimates of species richness can be dramatically different. It is necessary to have a homogeneous concept for taxonomic units. The abundance of the crinoid fossil record allows a discussion of the ancestry of deep sea crinoid fauna. Stalked crinoids have a horizontal diversity pattern with three regional centres of high diversity (i.e. western tropical Pacific, western tropical Atlantic and north-eastern Atlantic). Vertical patterns show two faunal strata which vary in importance among provinces. The epibathyal stratum has apparently remained relatively similar in intertropical areas since the Mesozoic. Despite environmental changes related to glaciation since the Middle Miocene, the deepest crinoid fauna (i.e. the deep sea fauna sensu stricto at depths more than 1000 ± 200 m) have a very ancient origin with a dispersion closely related to plate tectonics. The bathyal fauna on hard substrates includes a few living fossils and has a high historical interest.     

Aromatic hydrocarbon degradation patterns and catechol 2,3-dioxygenase genes in microbial cultures from deep anoxic hypersaline lakes in the eastern Mediterranean sea

Several mixed cultures able to grow on different aromatic hydrocarbons were obtained from different depths (between 3500 and 3660 m under the sea surface) of water/brine interfaces (1 to 5 m over the estimated brine surface) of three deep hypersaline anoxic basins (Urania, Discovery and Atalante) in the eastern Mediterranean sea. Eight strains which completely removed toluene from the medium in six to 10 days were isolated from one of the mixed cultures obtained from the Urania basin. The strains grew on toluene and yeast extract in the presence of NaCl concentrations of up to 50 and 100 g l(-1), respectively, indicating that they are halotolerant rather than halophilic. Even though DNA fingerprinting methods showed that the strains were strictly related, two groups could be found on the basis of the plasmid profile. Metabolic profiling and partial sequencing (350 bp) of the 16S rDNA showed that the strains were related to Pseudomonas mendocina. A 320 bp fragment of the catechol 2,3-dioxygenase gene from all the strains was aimplified by PCR. The sequence of the fragment showed 100% identity with xylE from pWW53 of Pseudomonas putida MT53 isolated from soil. Southern hybridisation experiments showed that catechol 2,3-dioxygenase is plasmid encoded.     

Observations on the development and maintenance of the deep sea barnacle,Octolasmis aymonini geryonophila (Pilsbry)

Thirty-two pedunculate barnacles, O. a. geryonophila, were maintained in culture for a period of 2 yr in the laboratory. These barnacles were obtained from the pleopods and mouth parts of the giant marine isopod, Bathynomus giganteus, which had been collected, at a depth of 200 fathoms, in the Gulf of Mexico.

The carina, scutum, mandible and maxilla of adult barnacles were typical of deep water species. However, the tergum and labrum were intermediate between those of shallow and deep water species.

Adults 3.1–4.1 mm in length were cultured in sea water (15–19°C), and fed on benthic copepods such as Tisbe furcata and Laophonte sp. Three broods of nauplii from 8 barnacles were obtained in 2 yr. Larvae were reared on plankton collected from Coney Island waters in which nauplii reached Stage IV in 10–14 days at 16°C. Isochrysis galbana and Thalassiosira pseudonana individually or in combination maintained nauplii to Stage IV, but with very high mortality. The lack of spines on the carapace edge of the nauplii distinguishes this deep water species from the shallow water form, O. mulleri.     

国家管辖范围以外区域海洋生物多样性保护的新视域: 包括海洋保护区在内的划区管理工具

随着人类对海洋资源开发利用强度的增加, 海洋生物多样性的养护面临更大挑战。联合国大会决定在《联合国海洋法公约》框架下拟定一份新的法律文书, 以解决国家管辖范围以外区域海洋生物多样性(marine biological diversity of areas beyond national jurisdiction, BBNJ)的养护与可持续利用问题。包括海洋保护区在内的划区管理工具(area-based management tools (ABMTs), including marine protected areas (MPAs))是BBNJ国际文书谈判的一个重要议题。目前谈判尚处于早期阶段, 各国对ABMTs/MPAs缺乏共同的观点。本文通过分析ABMTs/MPAs的定义和内涵以及两者的异同点、目标、与现有相关法律文书、框架和机构的关系、一般原则和方法、现有框架以及面临的缺乏调查数据、缺失全球性法律框架以及缺少利益相关者参与等挑战, 提出需提高设立海洋保护区的科学性、建立有效的监测与执法机制以及加强国际合作等建议。
