Fauna Europaea: Gastrotricha.

Fauna Europaea provides a public web-service with an index of scientific names (including important synonyms) of all living European land and freshwater animals, their geographical distribution at country level (up to the Urals, excluding the Caucasus region), and some additional information. The Fauna Europaea project covers about 230,000 taxonomic names, including 130,000 accepted species and 14,000 accepted subspecies, which is much more than the originally projected number of 100,000 species. This represents a huge effort by more than 400 contributing specialists throughout Europe and is a unique (standard) reference suitable for many users in science, government, industry, nature conservation and education.

[Homocysteine and cognitive functions in bipolar depression].

Aim: The aim of the study was to evaluate a relationship between concentrations of hoocysteine (HCY), vitamin B12 and folic acid and disturbances of cognitive functions during acute episode of bipolar depression.

Methods: 116 patients were studied (93 women, 23 men), aged 20-78 (mean 51±13) years during acute episode of bipolar depression. Depression was evaluated by the 17-item Hamilton's Depression Rating Scale (HDRS).

Checklist of Gastrotricha of the Polish Baltic Sea with the first reports of Heterolepidoderma joermungandri Kånneby, 2011, and Turbanella hyalina Schultze, 1853.

Gastrotricha is a cosmopolitan phylum of aquatic and semi-terrestrial invertebrates comprising more than 800 described species. Up to now, only five taxonomic and faunistic papers have been published on the gastrotrichs of the Polish Baltic Sea and 27 taxa have been found (including three freshwater, which were found in estuaries). This article presents a complete list of brackish and estuarine Gastrotricha from the Polish Baltic Sea accompanied by localities and the first observations of gastrotrich species inhabiting the underwater macrophytes.

Gastrotricha from the Poznań Palm House--one new subgenus and three new species of freshwater Chaetonotida (Gastrotricha).

Gastrotricha is a cosmopolitan phylum of aquatic and wet terrestrial invertebrates comprising about 800 described species. Gastrotrichs have never been studied in artificial habitats such as greenhouses. In this paper we present 13 species belonging to 5 genera of the family Chaetonotidae that have been found in a water body with tropical aquatic plants.
