Book Synopsis Grassland Invertebrates by : Jim P. Curry
Download or read book Grassland Invertebrates written by Jim P. Curry and published by Springer Science & Business Media. This book was released on 1993-11-30 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grasslands comprise more than a quarter of the Earth's land surface. In addition to supporting a wide range of vertebrates such as domestic livestock and a variety of games species, grassland is the natural habitat for a wide range of invertebrate species, and this book considers those which occur in grassland and their impact on soil fertility and herbage growth. It describes grassland as a habitat for invertebrates, the groups which occur there and their abudance. An extensive literature on grassland invertebrates scattered through numerous scientific journals and reports is drawn on in an attempt to develop an overview. In the opening chapter the major grassland types are considered and the features which influence the distribution and abudance of the invertebrates which inhabit them are discussed. Next the major taxonomic groups are reviewed in turn, with a brief account of their biology and ecology and of their ecosystem role. Some general features of grassland invertebrate communities are then described and teh factors which influence th epopulation densities of their constituent species are considered. Particular attentionm is given to the ways in which populations are influenced by management practices. The final and largest chapterdeals with the various ways in which invertebrates influence important grassland processes through ingestion of organic matter, interaction with injurious species is considered, with particular emphasis on the potential for achieving this through manipulating grassland management practices.
Book Synopsis Biodiversity of Soil Arthropods in a Native Grassland in Alberta, Canada by : Jeffrey S. Newton

This book was released on 2013 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils have traditionally been treated as a "black box" due to the challenges of studying this complex medium. The living component of soil consists of a complex network of roots and mostly very small, highly abundant, and extremely diverse group of microbes, protists, and other invertebrates. In my thesis I explore the diversity of subterranean ants living in a native grassland in Alberta, Canada, and their symbiotic relationship with root-feeding aphids and mealy bugs (Hemiptera: Sternorrhyncha). I identify multiple species of ants and Sternorrhyncha, with varying degrees of specificity of their symbiosis. I also conclude that there is little species-level host-plant specificity. The latter part of my thesis concerns mites and springtails, which are the most abundant soil micro invertebrates. Biomass of these extremely small organisms is difficult to assess, and as a result many estimation formulae based on body size measurements have been published. However, these estimation methods have rarely been tested. I review published formulae and tested them with newly acquired mite-weight data. While some formulae strongly over- or under estimate mite biomass, other models perform remarkably well. Using abundance and biomass data, I present the results of the effects of a summer of drought on native grassland soil mites. While drought normally negatively affects most soil arthropod densities, I observed an increase. While the mechanism is not yet clear, this result suggests that some grassland soil mite taxa may be able to benefit from drought conditions. Finally, I study how changes in environmental conditions, like predicted climate change, may affect native grassland communities. A full-factorial design was used, including a warming, drought, added precipitation, low intensity defoliation, and high intensity defoliation treatments. Results showed that all treatments affected the studied mite assemblages, but the effects differed per mite taxon. In summary, I have shown that the abundance and diversity of soil biota not only still offer opportunity for discovery, but also react to environmental changes in a way that allows them to be used as biomonitors. These responses vary according to which taxa are being studied, emphasizing the importance of not oversimplifying this rich and complex community.

Book Synopsis Economic and Ecological Significance of Arthropods in Diversified Ecosystems by : Akshay Kumar Chakravarthy
Download or read book Economic and Ecological Significance of Arthropods in Diversified Ecosystems written by Akshay Kumar Chakravarthy and published by Springer. This book was released on 2016-10-20 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Arthropods are invertebrates that constitute over 90% of the animal kingdom, and their bio-ecology is closely linked with global functioning and survival. Arthropods play an important role in maintaining the health of ecosystems, provide livelihoods and nutrition to human communities, and are important indicators of environmental change. Yet the population trends of several arthropods species show them to be in decline. Arthropods constitute a dominant group with 1.2 million species influencing earth’s biodiversity. Among arthropods, insects are predominant, with ca. 1 million species and having evolved some 350 million years ago. Arthropods are closely associated with living and non-living entities alike, making the ecosystem services they provide crucially important. In order to be effective, plans for the conservation of arthropods and ecosystems should include a mixture of strategies like protecting key habitats and genomic studies to formulate relevant policies for in situ and ex situ conservation. This two-volume book focuses on capturing the essentials of arthropod inventories, biology, and conservation. Further, it seeks to identify the mechanisms by which arthropod populations can be sustained in terrestrial and aquatic ecosystems, and by means of which certain problematic species be managed without producing harmful environmental side-effects. This edited compilation includes chapters contributed by over 80 biologists on a wide range of topics embracing the diversity, distribution, utility and conservation of arthropods and select groups of insect taxa. More importantly, it describes in detail the mechanisms of sustaining arthropod ecosystems, services and populations. It addresses the contribution of modern biological tools such as molecular and genetic techniques regulating gene expression, as well as conventional, indigenous practices in arthropod conservation. The contributors reiterate the importance of documenting and understanding the biology of arthropods from a holistic perspective before addressing conservation issues at large. This book offers a valuable resource for all zoologists, entomologists, ecologists, conservation biologists, policy makers, teachers and students interested in the conservation of biological resources.

Book Synopsis Grasslands in Europe by : Peter Veen
Download or read book Grasslands in Europe written by Peter Veen and published by BRILL. This book was released on 2014-04-14 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grasslands are an important element of European nature. About half of Europe's endemic species depend on grasslands, whether in mountains, lowlands, river plains or coastal areas. Many grasslands originate in traditional agricultural landscapes. Modern intensification, however, brings many of these ecosystems under threat. 'Grasslands in Europe' is a tribute to these important ecosystems. It was written by an international team of grassland experts, who describe twenty-four case studies from countries in all of Europe - ranging from the grasslands of Gotland and #land (Sweden) to the Spanish Dehesa, and from the hay meadows of the British Pennine Dales to the steppes of Turkish Anatolia. Together, these case studies provide a fascinating glimpse into the various European grasslands, their value for nature, culture and agriculture, and the threats they are facing today. The accessible text as well as the rich illustrations will appeal to a wide audience. Grasslands in Europe contains a large number of stunning full-colour photographs of grassland landscapes, species and cultural history. It also contains many maps and infographics. Thematic chapters provide essential background information on topics such as grassland fauna, the history of agriculture, grassland communities, and the connection between grasslands and climate. The book also analyses the opportunities and risks of EU policy to conserve these grasslands. It offers a farmer-centred outlook to manage and to maintain the European grasslands of high nature value.
