Book Description
Advances in Aquatic Microbiology Volume 1 describes the characteristics of ecological niches for individual microorganisms and the intensities of individual microbiological processes in the course of turnover of various substances in reservoirs. This volume follows Volume 1 of Advances in Microbiology of the Sea book. The opening chapter presents insight to the tradition of Russian limnological microbiology followed by a discussion on conversion of inorganic nitrogen to organic nitrogen, and the microorganisms responsible for assimilatory reactions. The book considers aspects of the reduction of atmospheric dinitrogen and nitrate to ammonia and the incorporation of ammonia into organic compounds. Such considerations will relate particularly to those organisms of significance in aquatic environments. The relations between prey and predator and their significance in the investigation both the behavior of the microorganisms themselves and the prey-predator situation in general are also discussed. Chapter 4 examines how viruses, bacteria, and fungi affect the blue-green algae and the development and regulation of algal blooms. The final two chapters summarize studies in freshwater sediment microbiology and the role of bacteria in water pollution monitoring. This book caters primarily to aquatic microbiologists, but limnological microbiologists, aquatic researchers, scientists, teachers, and students with courses in aquatic microbiology will find this book invaluable.

Book Description
"Zoological Record is published annually in separate sections. The first of these is Comprehensive Zoology, followed by sections recording a year's literature relating to a Phylum or Class of the Animal Kingdom. The final section contains the new genera and subgenera indexed in the volume." Each section of a volume lists the sections of that volume.

Book Description
It is also possible that contractile vacuoles originate by some form of phase separation not yet understood and possibly involving the contractile properties of proteins, and' it is possible that this process continues to operate in the walls of the vacuoles or feeder canals. This secretory process may be the function of that part of the vacuolar apparatus which blackens on impregnation with osmic acid, and which seems to possess some degree of permanence from vacuole to vacuole and in some cases from parent to daughter cell. Remarkably little is known about the mechanism of systole. General body turgor may contribute, but it is not essential. In ciliates the main force is local and probably comes from a tension in the wall of the vacuole itself, but it is not known whether or not this is an active contraction of an oriented protein layer. The critical process for the initiation of systole is probably the opening of the pore. It is possible that in ciliates there is a rhythmically operating independent timing mechani,sm by which the vacuolar cycle is controlled, but its existence has not been demonstrated.

Book Description
Indexes the world's zoological and animal science literature, covering all research from biochemistry to veterinary medicine. The database provides a collection of references from over 4,500 international serial publications, plus books, meetings, reviews and other no- serial literature from over 100 countries. It is the oldest continuing database of animal biology, indexing literature published from 1864 to the present. Zoological Record has long been recognized as the "unofficial register" for taxonomy and systematics, but other topics in animal biology are also covered.
