Rotifer occurrence in relation to age, depth and trophic state of quarry lakese even found in the youngest (2 years of age) one, Rogoźnica 4, but both rotifer density and species richness were low there. Rotifer communities of much higher density and species diversity were noted in lakes only 4–6 years older. Lakes of over 30 years of age were strongly differentiated in rotif

The main macrophytes present were species of . and ., and, in 1993, there was an extensive covering of .. Sampling methods included quantitative samples taken using a simple syringe. Rotifers numbered from about 10 to 150 per 100 ml and formed about 2 to 20% of the micr

Factors affecting the distribution of benthic and littoral rotifers in a large marine lagoon, togethngth. Some of the physical and chemical characteristics of the lagoon were examined and related to rotifer total abundance and species richness. A preliminary list of species found at different sampling stations is given. A strong negative correlation between salinity and total abundance was found.

Distribution and ecology of rotifer communities in high-altitude alpine sites — a multivariate approl of 162 substrate classified samples was taken at 60 sampling sites situated between 1824 m and 2753 m a.s.l. in the Central Alps (predominantly gneiss) and between 1290 m and 1643 m a.s.l. in the Northeastern Calcareous Alps. Multivariate analysis allowed the recognition of distinct sampling site

Numerical taxonomic studies of the genus aracters. All analyses converge on essentially identical groupings, but fail to inject new hypotheses to remedy the confusing and overlapping taxonomy of the genus. This shortcoming is ascribed to the incompleteness of the character set which currently lacks biochemical and genetic parameters. We su

Mating behavior and mate recognition pheromone blocking of male receptors in , Müller (Rotifera)cterized as a Mate Recognition Pheromone (MRP), binds to receptors in the corona of males and blocks mate recognition. Blocking was observed in all S and L strains even though the MRP was isolated from a single L-type strain. Binding was quantified using image analysis and a 20-fold difference was o
