Survival, culturing, adaptation and metal resistance of various rotifers and a gastrotrich (Minor phyla) isolated from heavily polluted industrial effluents.
To arrive at a better understanding of gastrotrich systematics and phylogeny, we performed the first cladistic analysis of nearly all known gastrotrich genera using 71 morphological characters.
The rest of taxa: nauplii larvae, gastrotrichs, kinorhynchs, polychaetes, oligochaetes and cumaceans exhibited low relative abundances (below 1%) and scarce taxonomic representation.
Protists, nematodes, rotifers, small crustaceans, tardigrades, gastrotrichs, turbellarians, oligochaetes, and insect larvae are regularly found from psammon habitats (Thane-Fenchel, 1968; Whitman and Clark, 1984; Schmid-Araya, 1998, Kotwicki et al.
Molecular phylogenies sometimes recover other groups such as rotifers and gastrotrichs nested within the core lophotrochozoans (e.
