We investigated monogonont rotifers in two natural Macedonian lakes that greatly differ in age, size and trophic state: Lake Ohrid and Lake Dojran. A main characteristic of Lake Ohrid is the scarcity of nutrients and consequently a low level of primary production. Lake Dojran represents a typical eutrophic lake. Results clearly indicate that species numbers(More)
Understanding patterns and processes in biological diversity is a critical task given current and rapid environmental change. Such knowledge is even more essential when the taxa under consideration are important ecological and evolutionary models. One of these cases is the monogonont rotifer cryptic species complex Brachionus plicatilis, which is by far the(More)
The distribution and ecology of benthic, periphytic and planktonic rotifers were investigated in a wide range of alpine waterbodies in Austria. A total 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(More)
Mating durations of copepods were found to differ significantly between fishless high-altitude waters and lowland lakes containing fish. In lowland species the whole mating process was completed within a few minutes, but it averaged over an hour in high-altitude species. Alpine copepods showed a prolonged post-copulatory association between mates, during(More)
Ongoing glacial retreat is expected to lead to numerous changes in glacier-fed rivers. This study documents the development of community composition of the hitherto widely neglected micro- and meiobenthos (MMB: bacteria, fungi, algae, protists, and meiofauna) in glacier rivers in response to the distinct habitat conditions driven by different stages of(More)
A new dicranophorid rotifer, Encentrum (Parencentrum) walterkostei n.sp., is described from an oligotrophic alpine lake. The species was abundant in the psammolittoral of the ‘Unterer Schwarzhornsee’, 2543 m above sea level. The main distinguishing taxonomic features of the new species are long, swordshaped toes and only four vitellary nuclei. Its known(More)
The International Rotifer Symposium held in České Budějovice, Czech Republic, from August 30th to September 4th 2015 was the 14th meeting of the rotifer family. These Symposia are a series of informal gatherings of researchers interested in rotifers. Participants usually include researchers who devotemost, if not all, of their time to aspects of rotifer(More)
Although closely resembling Anuraeopsis fissa, Anuraeopsis miracleae constitutes a well defined species, being more highly adapted to microaerobic, cold environments. Our observations on the Austrian population are compared with information available on specimens from the type locality in Spain. Morphological discrepancies, especially concerning(More)
Following ICZN (1999) Article 79 Chapter 17 http://www.nhm.ac.uk/hosted-sites/iczn/code/), we, with the full support of the international community of rotifer researchers as expressed during subsequent international Rotifera symposia, developed a Candidate Part of the List of Available Names for species and genera of Rotifera from the start of zoological(More)
