Plankton Rotifers


Book Description




Rotifers (Rotifera)


Book Description

Rotifers (Rotifera) are animals which occur in every type of aquatic environment, both marine and freshwater. They owe their wide distribution to rapid reproduction. Due to their abundance, they play an important role in freshwater ecosystems. There are around 2000 rotifer species, 1350 of them from Europe. This book provides a guide to rotifers, including topics such as the origin of rotifers, taxonomy and systematics, morphology, anatomy, biology, ecology, zoogeography, and methods of sample collection, preservation, storage, and processing. It also provides information on orders, families and genera, as well as a survey of species, based on illustrations including many original color micrographs. In total, over 460 rotifer species found in Poland are presented and characterized, as well as over 140 species found in neighboring countries.




Biology of Rotifers


Book Description

Since the two previous rotifer symposia in Lunz and Gent were highly successful, it was considered important to continue the tradition every third year. Thus a third rotifer symposium was held in Uppsala, Sweden, Aug. 30-Sept. 4, 1982. In the beginning of 1981 the first circular was mailed to the participants of the previous symposia, who in turn were requested to suggest names of other scientists to be invited. As a result many people expressed interest, about 70 of whom finally participated in the symposium (not including temporary visitors from nearby). The participants represented 22 countries, in Europe, North America, Asia and Australia. As with the earlier symposia, some subjects were selected in advance, mainly during discussions between Henri Dumont, Birger Pejler and Peter Starkweather when they met at the SIL congress in Kyoto 1980. Some broad topics such as 'Marine rotifers' were covered for the first time, while other topics were continuations, though more specialized, of previous themes. Thus it is interesting to follow, through the three symposium volumes, recent development within the areas of feeding, popUlation dynamics and ultrastructure. Each prospective participant (with the exception of the reviewers) was invited to present one short paper (alone or with collaborators), which resulted in more than 40 such contributions. Thus, the week's schedule became very crowded, unfortunately leaving no time for more comprehensive workshops etc. However, during the evenings general discussions were held on the topics presented during the day.




Rotifera X


Book Description

This volume reflects the latest developments in the research of a global community of rotifer researchers, who came together at Illmitz, Austria in 2003. Contributions are manifold and span fields from phylogeny and evolution of the phylum Rotifera to practical aspects of aquaculture and ecotoxicology. Major issues include phylogeny and evolution, genetics and molecular ecology, new aspects of rotifer anatomy through the application of confocal laser-scanning microscopy, anhydrobiosis, long-term studies in lakes and rivers, population dynamics and community ecology, trophic relationships between copepods and rotifers, alongside biodiversity studies based on classical taxonomic concepts and molecular approaches. Although primarily focussed on one taxonomic group, the scientific outcome of this meeting is of relevance to the study of other aquatic microinvertebrates as well.




Plankton Regulation Dynamics


Book Description

Continuous cultures, i.e. chemostats with an continuous dilution rate, are model ecosystems for the study of general regulation principles in plankton communities. Further to an introduction, general continuous culture methods and especially the characteristics of rotifer continuousculture systems are presented. Sections on metabolism and energetics in chemostats, growth models, competition and predator-prey interactions, as well as the application of rotifer continuous cultures to ecotoxicology and their use in aquaculture are included.







Rotifera IX


Book Description

This volume is a record of the proceedings of the IXth International Rotifer Symposium, which was held in Khon Kaen, Thailand, on January 16-23, 2000. The symposium was the first meeting of the international group of rotifer researchers held in Asia. The volume contains reviews and research papers dealing with diverse aspects of scientific research related to Rotifera and their ecology. Some of the topics addressed are: taxonomy and zoogeography, ecology, phylogeny and evolution, physiology, biochemistry and population genetics, aquaculture, and ecotoxicology. This book is special because it contains a unique compilation of contemporary rotifer-related research, and is the eighth of a series of rotifer symposium proceedings published in Developments of Hydrobiology. This update of Rotifera studies will be of great interest to invertebrate zoologists, hydrobiologists, ecologists, and aquaculturists, particularly those interested in freshwater habitats.




Large Lakes


Book Description

The vast majority of the world's lakes are small in size and short lived in geological terms. Only 253 of the thousands of lakes on this planet have surface areas larger than 500 square kilometers. At first sight, this statistic would seem to indicate that large lakes are relatively unimportant on a global scale; in fact, however, large lakes contain the bulk of the liquid surface freshwater of the earth. Just Lake Baikal and the Laurentian Great Lakes alone contain more than 38% of the world's total liquid freshwater. Thus, the large lakes of the world accentuate an important feature of the earth's freshwater reserves-its extremely irregular distribution. The energy crisis of the 1970s and 1980s made us aware of the fact that we live on a spaceship with finite, that is, exhaustible resources. On the other hand, the energy crisis led to an overemphasis on all the issues concerning energy supply and all the problems connected with producing new energy. The energy crisis also led us to ignore strong evidence suggesting that water of appropriate quality to be used as a resouce will be used up more quickly than energy will. Although in principle water is a "renewable resource," the world's water reserves are diminishing in two fashions, the effects of which are multiplicative: enhanced consumption and accelerated degradation of quality.




Rotifer Symposium VI


Book Description

As in previous symposia, some current research topics were selected for review and eight invited papers were presented. For the first time a paper was presented on the historical aspects of Rotiferology, covering European research between 1680-1950. A special workshop session was devoted to a debate on a controversial topic: Rotifer Phylogeny. The workshop resulted in a very successful discussion and the integration of scattered evidence and hypotheses on the phylogenetic origin of rotifers, the relationships between major rotifer groups, and the mechanisms of evolution.




Rotifer Symposium IV


Book Description

The fourth international rotifer symposium was Wednesday afternoon a tour of Edinburgh, includ held in Edinburgh, Scotland, August 18 - 25, 1985, ing a visit to the Palace of Holyrood, was arranged. hosted by the Institute of Terrestrial Ecology. This This was followed by an evening banquet with meeting continued the tradition of holding rotifer traditional Scottish entertainment. On Thursday symposia at three-year intervals. The first an evening most participants attended a fireworks dis nouncement of the fourth meeting was circulated at play which was part of the Edinburgh Festival. Fi the end of 1983 to almost 300 people whose names nally, an excursion to Loch Lomond and the Tros appeared on the mailing list of the international sach hills was arranged for the Saturday after the newsletter, Rotifer News. In total, 68 people from meeting. 23 countries attended the meeting. It is interesting The organisers would like to thank Mr. C. J. to note that, of these 68 participants, 21 had at Place and colleagues at the Institute of Terrestrial tended the first meeting, held in Linz, Austria, Ecology for their invaluable help in organising the 1976, and 13 had attended all three previous meet meeting and preparing the symposium volume for ings. publication. We are also grateful for financial sup As in previous symposia, some research topics port from the Royal Society, the British Council were identified in advance of the meeting as being and British Petroleum (Scotland).
