Download or read book Nematodes in Soil Ecosystems written by Diana W. Freckman and published by University of Texas Press. This book was released on 2014-11-06 with total page 221 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many species of the phylum Nematoda, the nonsegmented worms, play an important role as animal or plant parasites; most species are active contributors to the decomposition cycle in soil ecosystems, but the details of that contribution are just beginning to be understood. Agricultural nematologists, vitally involved in the study of the methodology, taxonomy, and biology of the species due to the direct relationship between crop yield and the size of plant-parasitic nematode populations, have provided much information about the nematodes. More recently, ecologists have contributed additional data on the structure and function of the total soil community, including energy flow and nutrient cycling, and have examined the critical and multifaceted role of soil nematodes in such communities. Nematodes in Soil Ecosystems provides a valuable synthesis of significant research in this area and may stimulate further important communication between the agricultural and ecological branches of nematode research.

Download or read book Nematodes as Environmental Indicators written by Michael John Wilson and published by CABI. This book was released on 2009 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nematodes are the most wide spread multicellular animals in nature and analysis of nematodes in terrestrial, freshwater and marine environments as well as their role and function in ecosystems, can be used for environmental monitoring. Compared to other organisms, they offer the greatest potential as bioindicators and can be used to study gene expression in relation to environmental challenges, to monitor changing impacts on the environment and in laboratory ecotoxicity tests. This volume addresses classical and molecular approaches to nematode community analysis, the contemporary field of nematodes as biosensors, as well as genomic aspects of nematode bioindicators. In addition, the case studies stress the importance of these bioindicators and demonstrate the commercial potential of these technologies.

Download or read book Ecology of Freshwater Nematodes written by Walter Traunspurger and published by CABI. This book was released on 2021-07-16 with total page 397 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Nematode Trapping Fungi written by Ke-Qin Zhang and published by Springer Science & Business. This book was released on 2014-04-22 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: These chapters provide up-to-date information on nematophagous fungi, particularly those of the Orbiliaceae in Ascomycota, whose asexual states produce nematode-trapping devices. The authors consider fungal-nematode interactions, fossil fungi, the biodiversity, ecology and geographical distribution of nematode-trapping fungi, and their potential use in biocontrol of nematodes, all in detail. Nematode-trapping fungi with adhesive or mechanical hyphal traps are the main focus of this book which begins with an overview of the data on nematode-trapping fungi, including their taxonomy, phylogeny and evolution. Subsequent chapters expand upon the methods and techniques used to study these fascinating fungi. Keys for genera of Arthrobotrys, Drechslerella and Dactylellina, which include all reported species of predatory orbiliaceous fungi are presented and numerous species from these genera are morphologically described and illustrated. The ecology of nematode-trapping fungi is expertly presented: their occurrence and habitats, their geographical and seasonal distribution and the effects of soil conditions and nematode density on their distribution all feature amongst the relevant themes. Further chapters examine the use of nematode-trapping fungi in biological control and the authors consider nematicidal activities in detail, exploring the many compounds from fungi that feature in nematicidal activities and of course useful paths for further study on this topic. This is a highly informative and carefully presented book, providing scientific insight for scholars with an interest in fungi and in biological control of nematodes.
