Un cas d'école : l'espèce type du genre Heterolepidoderma Remane (Gastrotriches, Chaetonotidae)
Bulletin mensuel de la Société linnéenne de Lyon, 2010L'année de description et de publication de la diagnose du genre Heterolepidoderma Remane (Gastrotriches, Chaetonotidae) étant controversée, les auteurs se sont livrés à une analyse critique des différentes publications dans lesquelles ce taxon a été utilisé au début, afin de déterminer la référence à prendre en compte comme étant celle de la ...

Baltic Sea Gastrotricha—one new species and one new record of Chaetonotida from Poland
Zootaxa, 2015Gastrotricha is a cosmopolitan phylum of aquatic and semi–aquatic invertebrates that comprise about 820 described species, which are divided into two orders: Chaetonotida Remane, 1925 [Rao & Clausen, 1970] and Macrodasyida Remane, 1925 [Rao & Clausen, 1970].

New species and records of freshwater Chaetonotus (Gastrotricha: Chaetonotidae) from Sweden
Zootaxa, 2013Chaetonotus is the most speciose genus of the family Chaetonotidae within Gastrotricha, a small phylum of aquatic acoelomate invertebrates. The freshwater gastrotrich fauna of Sweden has been studied during the last five years and so far 44 species have been reported in the literature from the country. This study describes the new species, Chaetonotus (

Many meiofaunal species are reported to be cosmopolitan, but due to uncertainties of identification, the affiliation of specimens from geographically distant areas to the same species-taxon is problematic. In this study, we examined morphological and molecular variation in samples of Xenotrichula intermedia Remane (Gastrotricha: Chaetonotida) from the ...

Partial 18S rRNA gene sequences of four macrodasyid and one chaetonotid gastrotrichs were obtained and compared with the available sequences of other gastrotrich species and representatives of various metazoan phyla. Contrary to the earlier molecular data, the gastrotrich sequences did not comprise a monophyletic group but formed two distinct clades ...

Gastrotricha is a cosmopolitan phylum of aquatic and semi-terrestrial invertebrates comprising over 820 described species. Virtually no taxonomic or faunistic data exist on freshwater Gastrotricha of the Arctic. So far, 10 studies have recorded Gastrotricha from the entire area of the Svalbard Archipelago; only in two were gastrotrichs determined to ...

Demographic life history data are used as a means of assessing effects of increasing concentrations of DDT on the longevity and reproductive rate of Lepidodermella squammata, a common aquatic micrometazoan, These obligate parthenogens were cultured individually in slide depressions, each juvenile being transferred to its own depression upon hatching ...

Two new genera and species of Gastrotricha are described from the psammon of a freshwater body in Brazil: Redudasys fornerise and Arenotus strixinoi. The former is the first undoubted member of the order Macrodasyida recorded from a freshwater environment.
