Diversity under a magnifier lens: the case of Typhlotanaidae (Crustacea: Tanaidacea) in the N Atlantic.

Research focusing on 'stout-bodied' typhlotanaids collected from several sites around Iceland and adjacent N Atlantic region has resulted in the description of 15 species new to science, as well as the creation of eight new genera. Typhlotanais eximius Hansen, 1913 is redescribed and transferred to a new genus, while Typhlotanais crassus and Peraeospinosus adipatus are transferred to the genus Larsenotanais. The morphological and the molecular data were combined to consolidate and confirm the validity of the results obtained from both approaches.

Mislabeling and nomenclatorial confusion of Kudinova-Pasternak, 1985 (Crustacea: Tanaidacea) and establishment of a new genus.

Re-examination of historical collections allowed us to resolve the taxonomic status of Kudinova-Pasternak, 1985, originally described based on a single specimen from Great-Meteor Seamount. The holotype of this species was considered lost and the species redescribed based on a second specimen from the type locality by Błażewicz-Paszkowycz (2007a), who placed on a newly established genus . Thorough morphological analysis of and species and recently obtained genetic data of typhlotanaids from N Atlantic and NW Pacific waters allow us to conclude that the redescription of by Błażewicz-Paszkowycz (2007a) was based on a wrongly labelled specimen that, rather than a type of , represents in fact a new species of .

gen. nov., sp. nov. (Crustacea, Tanaidacea) from the southeast Australian coast, with comments on the distribution and habitat preferences of Chondropodinae.

Based on material collected from the shelf off southeast Australia (offshore of Portland), a new genus and new species, gen. nov., sp.

Nematode responses to an Arctic sea-ice regime: morphometric characteristics and biomass size spectra.

Body size is one of the most important traits of organisms that affects their behavioral life histories, physiologies, and energy requirements. For sediment-dwelling organisms, such as free-living nematodes, body size is a direct adaptation for living in sediments with a particular particle size, but other environmental factors, e.g.

Integrative systematics and ecology of a new deep-sea family of tanaidacean crustaceans.

A new family of paratanaoidean Tanaidacea - Paranarthrurellidae fam. nov. - is erected to accommodate two genera without family classification (Paratanaoidea incertae sedis), namely Armatognathia Kudinova-Pasternak, 1987 and Paranarthrurella Lang, 1971.

Deep ocean seascape and Pseudotanaidae (Crustacea: Tanaidacea) diversity at the Clarion-Clipperton Fracture Zone.

Understanding the diversity and spatial distribution of benthic species is fundamental to properly assess the impact of deep sea mining. Tanaidacea provide an exceptional opportunity for assessing spatial patterns in the deep-sea, given their low mobility and limited dispersal potential. The diversity and distribution of pseudotanaid species is characterized here for the Clarion and Clipperton Fractures Zone (CCZ), which is the most extensive deposit field of metallic nodules.

New species of Typhlotanaidae (Crustacea, Tanaidacea) from the Brazilian coast: genera Hamatipeda, Meromonakantha and Paratyphlotanais, with description of Targaryenella gen. nov.

Benthic samples collected along the Brazilian coast yielded the description of four new species from three genera of Typhlotanaidae: one Hamatipeda (H. prolata), one Meromonakantha (M. mauri) and two Paratyphlotanais (P.

BioTIME: A database of biodiversity time series for the Anthropocene.

Motivation: The BioTIME database contains raw data on species identities and abundances in ecological assemblages through time. These data enable users to calculate temporal trends in biodiversity within and amongst assemblages using a broad range of metrics. BioTIME is being developed as a community-led open-source database of biodiversity time series.

Systematic and taxonomic observations on the subfamily Synapseudinae Guţu, 1972 and related metapseudid taxa (Crustacea: Tanaidacea: Apseudomorpha), with the erection of a new genus and descriptions of three new species.

The tanaidacean metapseudid subfamily Synapseudinae Guţu is reviewed, partially revised and the type species, Synapseudes minutus Miller, redescribed. As rediagnosed and defined here, the Synapseudinae is restricted to the genera Synapseudes Miller, Vicinisyndes Guţu, and Creefs Stępień Błażewicz-Paszkowycz. The genera Curtipleon Băcescu and Cryptapseudes Băcescu are excluded from this subfamily.
