Broad phylogenomic sampling improves resolution of the animal tree of life
TLDR
This data reinforce several previously identified clades that split deeply in the animal tree, unambiguously resolve multiple long-standing issues for which there was strong conflicting support in earlier studies with less data, and provide molecular support for the monophyly of molluscs, a group long recognized by morphologists.
The Magnitude of Global Marine Species Diversity
TLDR
The first register of the marine species of the world is compiled and it is estimated that between one-third and two-thirds of marine species may be undescribed, and previous estimates of there being well over one million marine species appear highly unlikely.
Higher-level metazoan relationships: recent progress and remaining questions
TLDR
The relationships of the five main metazoan lineages—Porifera, Ctenophora, Placozoa, Cnidaria and Bilateria—remain subject to conflicting topologies according to different taxonomic samples and analytical approaches.
Kinorhyncha from Disko Island, West Greenland
TLDR
This book describes Kinorhyncha from Disko Island, West Greenland as a coral Montastrea cavernosa (Linnaeus), and describes its classification as Echinoderes—Greenland—Disko Island—Classification.
The first record of cyclomorphosis in Tardigrada based on a new genus and species from Arctic meiobenthos1
TLDR
Preliminary histological and physiological investigations indicate that the cyclomorphotic stages tolerate freezing and lower salt concentration and the presence of the pseudosimplex (cyclomorphotic) stage is indicated in other eutardigrades.
Spiralian Phylogeny Informs the Evolution of Microscopic Lineages
TLDR
The emerging concept of a microscopic, acoelomate, direct-developing ancestor of Spiralia is reviewed and 402 orthologs mined from genome and transcriptome assemblies of 90 taxa are assessed.
The Tidal Genus Echiniscoides and Its Variability, with Erection of Echiniscoididae fam.n. (Tardigrada)1
TLDR
It can be concluded that two species of Echiniscoides exist and that E. sigismundi (M. Schultze, 1865) is a complex of small species mainly distinguished by its co‐variation of cutic‐ular and claw features.
Molecular phylogeny of Arthrotardigrada (Tardigrada).
Tardigrades are microscopic ecdysozoans with a worldwide distribution covering marine, limnic and terrestrial habitats. They are regarded as a neglected phylum with regard to studies of their
Submarine columns of ikaite tufa
In the small Ikka Fjord in southwestern Greenland, we have studied remarkable submarine tufa columns forming over alkaline springs by abiotic precipitationof the metastable, cold-water mineral ikaite
Ice formation in the freeze-tolerant eutardigrades Adorybiotus coronifer and Amphibolus nebulosus studied by differential scanning calorimetry
TLDR
This paper describes ice formation in two freeze-tolerant eutardigrades Adorybiotus coronifer and Amphibolus nebulosus, and suggests that the reduction in ice content is functionally related to increased amounts of water kept unfrozen due to interactions with macromolecules.
