Freshwater Meiofauna


Book Description

Meiofauna are a diverse and numerous component of the fauna in freshwater ecosystems, but have been mostly ignored by freshwater scientists. Freshwater Meiofauna aims to raise the awareness of this enigmatic, microscopic component of the freshwater biota, by providing the first-ever, comprehensive review of their biology and ecology. The first section of the book gives indepth accounts of the systematics, morphological characteristics, life histories and ecological requirements of the main freshwater meiofaunal taxa (i.e. microturbellarians, rotifers, gastrotriches, nematodes, water mites, microcrustaceans and tardigrades). The second section then takes an integrated approach to review the current state-of-play in meiofaunal ecological research in freshwaters, addressing important issues, such as the importance of meiofaunal taxa in the trophic dynamics of freshwater ecosystems and the process underpinning the distribution patterns observed in meiofaunal assemblages. This book should appeal to a wide range of freshwater scientists, including novices in the study of freshwater meiobenthology and established researchers in freshwater ecology, for whom the meiofauna represent an unopened "black box". Our ultimate goal is that this book will serve to promote the idea that the zoology of freshwater habitats concerns more than just fish, macroinvertebrates and microbes.




Freshwater Nematodes


Book Description

Nematodes are the most numerous metazoans in aquatic sediments. The majority of conducted studies on these aquatic forms focus mainly on those in marine and estuarine habitats. Nematodes from inland water bodies have been relatively forgotten or ignored.




Methods in Stream Ecology


Book Description

Methods in Stream Ecology, Second Edition, provides a complete series of field and laboratory protocols in stream ecology that are ideal for teaching or conducting research. This updated edition reflects recent advances in the technology associated with ecological assessment of streams, including remote sensing. In addition, the relationship between stream flow and alluviation has been added, and a new chapter on riparian zones is also included. The book features exercises in each chapter; detailed instructions, illustrations, formulae, and data sheets for in-field research for students; and taxanomic keys to common stream invertebrates and algae. With a student-friendly price, this book is key for all students and researchers in stream and freshwater ecology, freshwater biology, marine ecology, and river ecology. This text is also supportive as a supplementary text for courses in watershed ecology/science, hydrology, fluvial geomorphology, and landscape ecology. - Exercises in each chapter - Detailed instructions, illustrations, formulae, and data sheets for in-field research for students - Taxanomic keys to common stream invertebrates and algae - Link from Chapter 22: FISH COMMUNITY COMPOSITION to an interactive program for assessing and modeling fish numbers




New Horizons in Meiobenthos Research


Book Description

Since research on meiobenthos was last compiled in a textbook (2008/2009), the number of theoretical and applied studies has been growing rapidly. Supported by new methods and digital evaluation, meiobenthology has developed into a wide field, with more and more researchers studying cross-disciplinary aspects. New perspectives were summarized in a booklet (2019) to draw attention to promising research directions. The present book, written by leading experts, is a compilation of new thinking, data, methods and approaches in many relevant fields of recent meiobenthos research. The topics addressed range from bacteria and biofilms to globally changing processes, from polar regions to the deep-sea and from freshwater ecosystems to the ocean. So, this book is not simply another meiobenthos textbook - it is an attempt to identify new horizons in meiobenthos research, driven by the vision of advancing knowledge and understanding of benthic ecosystems.




Meiobenthology


Book Description

This is a comprehensive treatise on meiobenthology, the science of small animals which live, often disregarded even by zoologists, in huge numbers in all aquatic sediments. Covering all the scientific literature on the subject, particular emphasis is placed on ecological and systematic aspects. After a survey of the biotope conditions and important methods, the animals are introduced in a systematic account. This is followed by a report on the meiobenthos in relevant biotopes. The book concludes with an analysis of the productive role and the position of meiofauna in the food web and perspectives for future research.




Freshwater Ecology and Conservation


Book Description

This practical manual of freshwater ecology and conservation provides a state-of-the-art review of the approaches and techniques used to measure, monitor, and conserve freshwater ecosystems. It offers a single, comprehensive, and accessible synthesis of the vast amount of literature for freshwater ecology and conservation that is currently dispersed in manuals, toolkits, journals, handbooks, 'grey' literature, and websites. Successful conservation outcomes are ultimately built on a sound ecological framework in which every species must be assessed and understood at the individual, community, catchment and landscape level of interaction. For example, freshwater ecologists need to understand hydrochemical storages and fluxes, the physical systems influencing freshwaters at the catchment and landscape scale, and the spatial and temporal processes that maintain species assemblages and their dynamics. A thorough understanding of all these varied processes, and the techniques for studying them, is essential for the effective conservation and management of freshwater ecosystems.




Ecology of Freshwater Nematodes


Book Description

Nematodes are incontestably the most numerous and the most diverse metazoans in freshwater habitats, and these properties bestow exceptional significance to their role in the environment. An array of functional roles has been attributed to them: they are grazers on bacteria and primary producers, regulators of decomposition of plant material, predators, prey for other animals, and closely associated symbionts of bacteria and other organisms. Freshwater nematodes are central in the context of environmental monitoring, pollution assessments, global warming and food webs, and this is increasingly being recognized. Moreover, the short generation time (a few days to months) of many species makes nematodes ideal for laboratory studies. This book offers guidelines for studying the ecology of free-living nematodes, including detailed protocols and case studies.




Ecology and Classification of North American Freshwater Invertebrates


Book Description

"The third edition of Ecology and Classification of North American Freshwater Invertebrates continues the tradition of in-depth coverage of the biology, ecology, phylogeny, and identification of freshwater invertebrates from the USA and Canada. This text serves as an authoritative single source for a broad coverage of the anatomy, physiology, ecology, and phylogeny of all major groups of invertebrates in inland waters of North America, north of Mexico." --Book Jacket.




Nematoda


Book Description

This section of the Handbook of Zoology is intended as a comprehensive and exhaustive account of the biology of the taxa Gastrotricha, Nematoda, Nematomorpha, Priapulida, Kinorhyncha, Loricifera, Gnathostomulida, Micrognathozoa, Rotifera, Seisonida and Acanthocephala, covering all relevant topics such as morphology, ecology, phylogeny and diversity. The series is intended to be a detailed and up-to-date account of these taxa. As was the case with the first edition, the Handbook is intended to serve as a reliable resource for decades. Many of the taxa of this volume are comparatively unknown to many biologists, despite their diversity and importance for example in meiofaunal communities (Gastrotricha, Rotifera, Gnathostomulida), their fascinating recent discoveries (Loricifera and Micrognathozoa), their importance as parasites (many nematodes, Nematomorpha, Acanthocephala) and their importance for evolutionary questions (e.g. Priapulida, Gastrotricha). The groups covered range from those poor in species (such as Micrognathozoa with 2 known species) to the species-rich and diverse Nematoda and their ca. 20.000 described species. While each taxon is covered by one chapter, nematodes are treated in several chapters dedicated to their structural, taxonomic and ecological diversity.




Freshwater Animal Diversity Assessment


Book Description
