Download or read book Water Bears The Biology of Tardigrades written by Ralph O. Schill and published by Springer. This book was released on 2019-02-14 with total page 418 pages. Available in PDF, EPUB and Kindle. Book excerpt: Offering extensive information on tardigrades, this volume begins with a chapter on the history of tardigrades, from the first description by Goeze in 1773, until 1929, when the most comprehensive monographic approach by E. Marcus was published. Tardigrades’ organ systems, including their integument, body cavity, digestive, muscular, nervous and reproductive systems, as well as their overall external morphology, are summarized in the second chapter. Subsequent chapters present the current state of knowledge on tardigrade phylogeny, biogeography, paleontology, cytology and cytogenetics. In addition, the book provides insights into the ecology of tardigrades in marine, freshwater and terrestrial habitats. The reproduction, development and life cycles are summarized and the extraordinary environmental adaptations of encystment and cyclomorphosis, desiccation tolerance, freezing tolerance and radiation tolerance are discussed in detail. Further chapters provide an overview of key approaches in molecular tardigrade studies and describe techniques for sampling and sample processing. The book closes with a list of tardigrade taxa up to a sub-generic level, including the type species of each genus, the numbers of lower taxa in each taxon, and the main environments in which the taxa were found. Given its depth of coverage, the volume offers an invaluable resource for scientists from various disciplines who plan to research tardigrades, and for all others who are interested in these fascinating animals.

Download or read book Paleoecology Biostratigraphy Paleoceanography and Taxonomy of Agglutinated Foraminifera written by Christoph Hemleben and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1002 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agglutinated foraminifera are among the most widely distributed and abundant groups of marine meiofauna in some environments (e. g. marshes, deep-sea). They are tolerant of environmental extremes, tending to live where the evolutionarily more advanced calcareous foraminifera cannot survive. However, largely because of historical reasons, the amount of scientific effort invested in this group has been small in comparison to studies of other marine organisms. The NATO Advanced Studies Institute conference on the paleoecology, biostratigraphy, paleoceanography and taxonomy of agglutinated foraminifera in TUbingen September 17-29, 1989, was a direct outgrowth of two previous workshops on agglutinated foraminifers held in Amsterdam in September 1981 (IW AF I) and in Vienna in June 1986 (IW AF 11). As such, the TUbingen conference constitutes the Third International Workshop on Agglutinated Foraminifera (IW AF III) and was organised to provide a platform for synthesizing the current state of knowledge on this group of organisms, and to strengthen interactions between basic research and applied micropaleontology. One of the main underlying themes of the conferen:e was to identify topics in the paleoecology, biostratigraphy, paleoceanography and taxonomy of agglutinated foraminifera which are in urgent need of further research. About 80 scientists and students from 5 continents participated in the TUbingen conference, which is one measure of the growth in interest in agglutinated foraminifers over the past decade. During four days of technical sessions, scientific results were communicated in the form of 34 oral presentations and 15 poster displays.
Download or read book Soil Protozoa written by J. F. Darbyshire and published by Oxford University Press, USA. This book was released on 1994 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protozoa are active components of the soil microfauna. For example, they may stimulate bacterial metabolism and some fungal metabolites can lyse protozoa. They may be predators of bacteria and hence have a role in biological control. Their presence in groundwaters can be used as an indicator of pollution, while they are also being used to treat sewage in the activated-sludge and reed-bed processes. They are believed to be major secondary decomposers in soil and increased knowledge about these microorganisms is important to sustain soil fertility and food production. This book is the first in English for 65 years devoted entirely to soil protozoology. It is written by experienced microbiologists and should be of interest to protozoologists, other microbiologists, and soil scientists.

Download or read book A Manual of Zoology written by Richard Hertwig and published by . This book was released on 1912 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Manual of Zoology The favor with which the first and second American editions of Hertwig's Zoology have been received has led to a thorough revision of the whole with a close comparison with the latest German edition. In this there have been introduced many new features bringing the work up to date. These include a discussion of Mendelian inheritance, many modifications in the account of the theory of evolution, and a considerable enlargement of the Protozoa and especially of the pathogenic forms, making the volume of more value to the student of medicine. To have included these without changes elsewhere would have resulted in a much larger volume. But the demand in American colleges has been for a smaller work and so a reduction has been made in two ways. There has been a condensation by the elimination of unnecessary words and phrases and by the omission of considerable matter of minor importance. Then there has been the recognition of the fact that the book has two uses, one in the class room the other as a reference work. The two classes of matter have been distinguished by difference of type. No attempt has been made to bring the systematic names into accord with the latest vagaries of the systematists. No useful and could be served by changing or transferring the well-known names of Echidna, Coluber, Amia, Homarus, Unio, Holothuria, Am ba, etc., while the confusion this would introduce would be enormous. It should be understood that while the revision is based upon the German edition of Professor Hertwig, he should not be held responsible for any changes introduced. The whole responsibility for these rests upon the American reviser.

Download or read book Marine Ornamental Shrimp written by Ricardo Calado and published by John Wiley & Sons. This book was released on 2009-03-16 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine ornamental shrimp are amongst the most heavily traded invertebrate species in the aquarium industry. The majority of traded species are still collected from the wild, having a major effect on ocean ecosystems. An increase in the amount of culture of these species is now a major priority for those in the trade and for marine conservationists. Marine Ornamental Shrimp provides a global overview of the biology, culture and conservation of the major families of marine ornamental shrimp. Coverage in this thorough volume includes ecological aspects, reproductive biology, major techniques used in culture systems for maturation, larviculture, and juvenile growth, and details of the main conservation issues surrounding these important species including a discussion of the negative aspects of wild specimen collection and the ongoing efforts to mitigate such impacts. Marine Ornamental Shrimp is an important and extremely timely publication which will be an essential reference and manual for all those involved in the trade and culture of marine ornamental species, including aquaculture scientists and personnel in aquaria. Conservation biologists and invertebrate zoologists will also find much of importance within this book. Libraries in all universities and research establishments where aquaculture and biological sciences are studied and taught should have copies of this book on their shelves.
