Aim The brackish water mysid, Neomysis integer, is one of the most common mysid species along the coasts of the north-east Atlantic. In the present study, the phylogeographical patterns were examined throughout the distribution range of N. integer. I

Streptocephalus sirindhornae, new species, the first freshwater anostracan from Thailand, is widespread in the northeast of the country. It is morphologically closest to the Indian species S. dichotomus, but a sequence analysis of its SSU rDNA gene r

Axenic mass cultivation of Acanthamoeba castellanii in laboratory fermentors (141) yielded after 20 days approximately 3 g cells (wet weight). After a short lag phase amoebal cell numbers increased exponentially to a maximum of 3.5 x 10(5) cells per

A simple procedure for the axenic cultivation of the free-living soil amoebae Acanthamoeba castellanii and Hartmannella vermiformis in chemostats was developed. Amoebal cell numbers, optical density and protein concentrations were determined to quant

Free-living soil amoebae consume a wide variety of food, including algae, yeast, small protozoa and especially bacteria, which they digest to fulfil their nutritional requirements. Amoebae play an active role in the nitrogen mineralization in soils d

The nuclear small subunit ribosomal DNA (18S rDNA) of 27 anostracans (Branchiopoda: Anostraca) belonging to 14 genera and eight out of nine traditionally recognized families has been sequenced and used for phylogenetic analysis. The 18S rDNA phylogen
