Diversity of Meiofauna from the 9°50′N East Pacific Rise across a Gradient of Hydrothermal Fluid Emissions
TLDR
The data suggest that with increasing temperature and toxic hydrogen sulfide concentrations and increasing amplitude of variation of these factors, fewer species are able to cope with these extreme conditions, which results in less diverse communities in more extreme habitats.
Comparison of molecular species identification for North Sea calanoid copepods (Crustacea) using proteome fingerprints and DNA sequences
TLDR
Proteomic fingerprinting using the MALDI‐TOF MS is recommended as an alternative or supplementary approach for rapid, cost‐effective species identification for pelagic calanoid copepod species identification.
Molecular Phylogeny and Revision of Copepod Orders (Crustacea: Copepoda)
TLDR
The phylogenetic relationships between representatives of all 10 copepod orders have been investigated using 28S and 18S rRNA, Histone H3 protein and COI mtDNA and the monophyly of Copepoda is demonstrated for the first time using molecular data.
A Reverse Taxonomic Approach to Assess Macrofaunal Distribution Patterns in Abyssal Pacific Polymetallic Nodule Fields
TLDR
This work tested to what extent distance and large-scale changes in environmental parameters lead to differentiation in two macrofaunal taxa exhibiting different functions and life-history patterns, and indicated high local and regional diversity mostly because of large numbers of singletons in the samples.
Spatially structured populations with a low level of cryptic diversity in European marine Gastrotricha
Species of the marine meiofauna such as Gastrotricha are known to lack dispersal stages and are thus assumed to have low dispersal ability and low levels of gene flow between populations. Yet, most
Molecular taxonomy confirms morphological classification of deep-sea hydrothermal vent copepods (Dirivultidae) and suggests broad physiological tolerance of species and frequent dispersal along ridges
TLDR
It is suggested that Dirivultid copepods have relatively high gene flow between vents and are able to disperse relatively easy along ridges and thus might not have undergone speciation in response to heterogeneity caused by vent fluids.
Ameiridae Boeck and Argestidae Por revisited, with establishment of Parameiropsidae, a new family of Harpacticoida (Crustacea, Copepoda) from deep-sea sediments
TLDR
A new family is proposed for Parameiropsis, with unclear relationships within Harpacticoida, because it does not have any character that could justify its inclusion within Ameiridae or even within Podogennonta and cannot be included satisfactorily within Argestidae nor Exanechentera.
Resilience of benthic deep-sea fauna to mining activities.
Distribution of free-living marine nematodes in the Clarion–Clipperton Zone: implications for future deep-sea mining scenarios
Abstract. Mining of polymetallic nodules in abyssal seafloor sediments promises to address the growing worldwide demand for metallic minerals. Given that prospective mining operations are likely to
Ultrastructure of protonephridia in Xenotrichula carolinensis syltensis and Chaetonotus maximus (Gastrotricha: Chaetonotida): comparative evaluation of the gastrotrich excretory organs
TLDR
A comparison with the protonephridia of other species of the Gastrotricha allows hypothesising the following autapomorphies of the Paucitubulata: The bicellular terminal organ with a composite filter, the convoluted distal canal cell lumen and the absence of cilia, ciliary basal structures and microvilli within the canal cell.
