Physiology of the Cladocera


Book Description

Physiology of the Cladocera, Second Edition, is a much-needed summary of foundational information on these increasingly important model organisms. This unique and valuable review is based on the world's literature, including Russian research not previously widely available, and offers systematically arranged data on the physiology of Cladocera, assisting with explanation of their life and distribution. It features the addition of new sections and a vast amount of new information, such as the latest data on feeding, nutrition, pathological physiology, chemical composition, neurosecretion, and behavior, as well as hormonal regulation, antioxidants, and the biochemical background of effects of natural and anthropogenic factors. Additional expertly updated contributions in genetics and cytology, and a new chapter in embryology, round out the physiological chapters, and provide comprehensive insight into the state of knowledge of Cladocera and their underlying mechanisms. Cladocera crustaceans have become globally studied for many purposes, including genetic, molecular, ecological, environmental, water quality, systematics, and evolutionary biology research. Since the genome of Daphnia was sequenced and published, that system has gained much wider exposure, also leading to a rapidly growing awareness of the importance of understanding physiological processes as they relate to evolutionary and ecological genomics as well as ecogenomic toxicology. However, the physiological background on Cladocera has been fragmentary (including on the other 700 known species besides Daphnia), despite the extensive literature on species identification and morphology. This work addresses this issue by collecting and synthesizing from the literature the state of knowledge of cladoceran physiology, including discussion on both adequately and inadequately investigated fields, and thus directions of future research. - Summarizes fundamental information obtained in recent years, including on steroids, antioxidants, hormones, nanoparticles, and impact of wastewater of pharmaceutical industries - Provides the foundational information needed for scientists and practitioners from a variety of fields, including conservation and evolutionary biology, genomics, ecology, ecotoxicology, comparative physiology, limnology, zoology–carcinology, and water quality assessment - Features coverage of both Daphniids and representatives of other families, with attention drawn to little-studied aspects of their physiology, especially of those living in the litt oral zone - Includes guidance to the literature on cladoceran physiology in four languages - Discusses advantages and shortcomings of Cladocera as experimental animals and indicators of water quality




Cladocera: the Biology of Model Organisms


Book Description

Cladocerans are increasingly used in many fields of science and this volume covers a wide range of such topics. Cladocerans have a strong influence on freshwater ecosystems and in some aspects they can be used in biomanipulation projects. Their fast and easy asexual reproduction offers a wide range of possibilities for studies in many fields of research: genetics, ecology, ecotoxicology, etc. In some ways they are the Drosophila of the present day. Their global distribution makes them of special interest from a phylogenetic and biogeographic as well as an ecological point of view. Apart from the proceedings of previous symposia, there are no other books which cover the whole range of aspects. These proceedings update the last symposia as well as including completely new information on certain fields of research. Target groups are research scientists within ecology, systematic biology, evolutionary biology and population biology. The book could also be a useful source of information for special courses for students of the above mentioned topics.




Cladocera as Model Organisms in Biology


Book Description

The Third International Symposium on Cladocera, papers from which make up this volume, covered recent findings on the behaviour, life history, population genetics, reproduction, chemical communication, predator-prey interactions, epibionts, taxonomy, phylogeny, palaeolimnology and biogeography of this animal group. The Cladocera occupy an intermediate position in lake ecosystems, both as plankton and benthic organisms. Their often high abundance and their function, as transfer organisms from algae and dead organic matter to macro-invertebrates and fish, make them one of the most important organisms to affect the biological processes in freshwater ecosystems. The Cladocera living among the plankton often have recognizable distribution patterns and migrations; their size and brief life cycles make them popular in laboratory experiments; their cyclic parthenogenesis makes them suitable for many aspects of population genetics; and they are present as microfossils in lake sediments. All these features confer a unique status on the Cladocera as model organisms in many aspects of modern systematics and ecology.

Cladocera


Book Description

There is a strong tendency now for specialists in various groups of organisms, or in various processes and their consequences, to get together at more or less regular intervals to discuss their subjects. This has hap pened e. g. with the Chironomidae, Ephemeroptera, and Plecoptera among the aquatic insects, and the Rotifera, Copepoda, and Ostracoda among the zooplankton. Finally the scientists working with the Cladocera, who have been isolated from one another for a long time except on a personal basis, have decided to do the same, largely through the initiative and drive of L. Forro. Thus, the First International Symposium on Cladocera was held in Budapest on 12-16 August 1985. Most of the roughly 60 attendees were from Euro pean countries, although a fair number came from Australia, Canada, India, Nigeria, and the United States. The accompanying table presents a list of attendees by country of origin. Regrettably, a number of persons who had expressed interest in coming were unable to do so. Their names and, in two instances countries, enclosed in brackets, are given to indicate the overall extent of topics that would have been discussed. Persons who presented papers or posters are indicated by an asterisk (*). The names of persons who chaired sessions are printed in italics. A total of 34 papers and 10 posters was presented, most of which are included in this volume.







Thorp and Covich's Freshwater Invertebrates


Book Description

Readers familiar with the first three editions of Ecology and Classification of North American Freshwater Invertebrates (edited by J.H. Thorp and A.P. Covich) will welcome the comprehensive revision and expansion of that trusted professional reference manual and educational textbook from a single North American tome into a developing multi-volume series covering inland water invertebrates of the world. The series entitled Thorp and Covich's Freshwater Invertebrates (edited by J.H. Thorp) begins with the current Volume I: Ecology and General Biology (edited by J.H. Thorp and D.C. Rogers), which is designed as a companion volume for the remaining books in the series. Those following volumes provide taxonomic coverage for specific zoogeographic regions of the world, starting with Keys to Nearctic Fauna (Vol. II) and Keys to Palaearctic Fauna (Vol. III). Volume I maintains the ecological and general biological focus of the previous editions but now expands coverage globally in all chapters, includes more taxonomic groups (e.g., chapters on individual insect orders), and covers additional functional topics such as invasive species, economic impacts, and functional ecology. As in previous editions, the 4th edition of Ecology and Classification of North American Freshwater Invertebrates is designed for use by professionals in universities, government agencies, and private companies as well as by undergraduate and graduate students. - Global coverage of aquatic invertebrate ecology - Discussions on invertebrate ecology, phylogeny, and general biology written by international experts for each group - Separate chapters on invasive species and economic impacts and uses of invertebrates - Eight additional chapters on insect orders and a chapter on freshwater millipedes - Four new chapters on collecting and culturing techniques, ecology of invasive species, economic impacts, and ecological function of invertebrates - Overall expansion of ecology and general biology and a shift of the even more detailed taxonomic keys to other volumes in the projected 9-volume series - Identification keys to lower taxonomic levels




Freshwater Crustacean Zooplankton of Europe


Book Description

This work provides a user-friendly, species level taxonomic key based on morphology, current nomenclature, and modern taxonomy using molecular tools which fulfill the most pressing needs of both researchers and environmental managers. This key arms the reader with the tools necessary to improve their species identification abilities. This book resolves another issue as well: the mix of female and male characters used in keys to the calanoid copepods. Often, during the identification process, both calanoid copepod sexes are not available, and the user of such a key is stuck with an uncertain identification. Here, separate male and female keys to the calanoid copepods are provided for both the genera and species levels.







Biodiversity Hotspot of the Himalaya


Book Description

Biodiversity is declining at an alarming rate due to anthropogenic activities around the world. This book is the second volume in the new series Biodiversity Hotspots of the World, which highlights the 36 hotspot regions of the world, regions that have been designated as reaping maximum benefit from preservation efforts. This series is our humble attempt to document these hotspots as a conservation and preservation measure. The concise volumes in this series focus on the most interesting and important properties of these hotspots, covering physiography and climatology; vegetation and forest types; amphibian and reptile biodiversity; genetic diversity of crops, plants, fishes, butterflies, insects, birds, mammals, angiosperms, and gymnosperms; and much more. And of course, the unique threats and conservation efforts for the areas are addressed as well. The Himalayan Mountains are the highest mountain range in the world and include Mount Everest as well as eight other highest peaks of the world. While it is difficult to document the biodiversity of this inhospitable terrain, we do know that out of the 9,000 different species of plants recorded in the area, 3,500 plants are endemic to the Eastern Himalaya region. Anthropogenic activities including deforestation, fragmentation of habitats, pollution, high population, climate change, and poaching of wildlife pose serious threats to the biodiversity of the region. The highlands have exceptionally rich biodiversity, high endemism, and over 160 globally threatened species, including the densest population of Bengal tigers and the three largest herbivores on the continent: the Asian elephant, greater one-horned rhinoceros, and wild water buffalo. The region boasts the world’s richest counts of alpine flora within its temperate broad-leaved forests, with a total of 10,000 species of plants. This volume, Biodiversity Hotspot of the Himalayas, as well as the other volumes in this series, will be essential resources for researchers and practitioners in the fields of conservation biology, ecology, and evolution as the series concisely records the existing biodiversity of these hotspots of the world.
