Download or read book Impact of Fire on Tussock Grassland Invertebrate Populations written by Barbara I. P. Barratt and published by Publishing Team Department of Conservation. This book was released on 2009-01-01 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The invertebrate fauna of tussock grassland in New Zealand has not been well studied, and the effect of burning on the biodiversity of the ecosystem is poorly understood by land managers. The impacts of burning on two tussock grassland invertebrate communities in Otago, New Zealand, were investigated between 1998 and 2006. At each site, three replicate 1-ha plots that were unburned (control), or burned in spring or summer were sampled. Pre- and post-burn sampling compared invertebrate densities and trophic group structure in inter-tussock (turf) and tussock samples, and recovery after treatment. Most groups were initially reduced in density post-burn. In the 1-2 year period following treatment, Thysanoptera and Hemiptera "rebounded" and reached significantly higher population densities than before the fires. By the end of the study, Amphipoda had not recovered to pre-burn densities. In general, herbivore population densities recovered over a 2-3 year period, and litter-dwelling invertebrate population densities were most negatively impacted. Season of treatment had no major impact on invertebrate responses. Coleoptera were chosen as a representative group for more detailed investigations of responses at species level. Coleoptera species richness was reduced by about 50% at 2-3 months post-burn, but recovered to pre-burn levels 3 years later. There was no evidence of a change in the density of exotic Coleoptera following the burning treatments. Invertebrate data from these sites should be considered as case studies, rather than applicable to tussock grassland in general. However, these findings have several implications for the management of tussock grassland: fire treatments that remove the litter layer are likely to reduce litter-dwelling invertebrate populations for 3 years or more; summer fires do not appear to be more detrimental to the invertebrate community than burning in spring, based upon the limited seasonal data available to us; and the exotic component of the fauna does not increase in response to fire in the first 3-4 years after burning.
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.

Download or read book Ecology written by Michael Begon and published by John Wiley & Sons. This book was released on 2020-11-17 with total page 864 pages. Available in PDF, EPUB and Kindle. Book excerpt: A definitive guide to the depth and breadth of the ecological sciences, revised and updated The revised and updated fifth edition of Ecology: From Individuals to Ecosystems – now in full colour – offers students and practitioners a review of the ecological sciences. The previous editions of this book earned the authors the prestigious ‘Exceptional Life-time Achievement Award’ of the British Ecological Society – the aim for the fifth edition is not only to maintain standards but indeed to enhance its coverage of Ecology. In the first edition, 34 years ago, it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, from which the ecological communities around us were simply material for which we sought a scientific understanding. Now, we must accept the immediacy of the many environmental problems that threaten us and the responsibility of ecologists to play their full part in addressing these problems. This fifth edition addresses this challenge, with several chapters devoted entirely to applied topics, and examples of how ecological principles have been applied to problems facing us highlighted throughout the remaining nineteen chapters. Nonetheless, the authors remain wedded to the belief that environmental action can only ever be as sound as the ecological principles on which it is based. Hence, while trying harder than ever to help improve preparedness for addressing the environmental problems of the years ahead, the book remains, in its essence, an exposition of the science of ecology. This new edition incorporates the results from more than a thousand recent studies into a fully up-to-date text. Written for students of ecology, researchers and practitioners, the fifth edition of Ecology: From Individuals to Ecosystems is anessential reference to all aspects of ecology and addresses environmental problems of the future.

Download or read book Biology of Rove Beetles Staphylinidae written by Oliver Betz and published by Springer. This book was released on 2018-05-15 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rove beetles (Staphylinidae) are common elements of the soil biota, living in the litter and deeper soil layers. Although they are one of the most diverse and speciose groups of insects, no comprehensive books on their general evolution and ecology are as yet available. This book fills that gap, discussing significant aspects and active research examples in the fields of phylogeny and systematics, ecology and conservation, and reproduction and development. The combination of review chapters and case studies provides an excellent introduction to the biology of rove beetles and enables readers to become familiar with active research fields in this megadiverse group of beetles. Offering easy access to these fields, it also demonstrates how staphylinids are used as bioindicators in applied ecosystem research, including that concerning conservation issues. Experienced scientists and beginners alike find the diversity of subjects covered intriguing and inspiring for continuing and starting their own research. The book is intended for students and researchers in biology and zoology (entomology), including morphologists, ecologists, soil scientists, evolutionary biologists, paleontologists, biogeographers, taxonomists and systematists.

Download or read book Phenology An Integrative Environmental Science written by Mark D. Schwartz and published by Springer Science & Business Media. This book was released on 2011-04-28 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenology is the study of plant and animal life cycle events, which are triggered by environmental changes, especially temperature. Wide ranges of phenomena are included, from first openings of leaf and flower buds, to insect hatchings and return of birds. Each one gives a ready measure of the environment as viewed by the associated organism. Thus, phenological events are ideal indicators of the impact of local and global changes in weather and climate on the earth's biosphere. Assessing our changing world is a complex task that requires close cooperation from experts in biology, climatology, ecology, geography, oceanography, remote sensing and other areas. This book is a synthesis of current phenological knowledge, designed as a primer on the field for global change and general scientists, students and interested members of the public. With contributions from a diverse group of over fifty phenological experts, covering data collection, current research, methods and applications, it demonstrates the accomplishments and potential of phenology as an integrative environmental science.

Book excerpt: In order to manage the world's increasingly scarce water resources we must have a sound understanding of how water moves around the planet and what influences water quality. Fundamentals of Hydrology provides an engaging and comprehensive introduction to this subject and provides real-life examples of water resource management in a changing world. The second edition of this popular book brings the text up-to-date with additional case studies and diagrams and a greater synthesis of water quality with physical hydrology. The chapters on runoff and evaporation have been updated and the final chapter on hydrology in a changing world has more material on water resource management strategies. Additionally the chapter on streamflow analysis now includes a more in-depth section on modelling runoff. The book begins with a comprehensive coverage of precipitation, evaporation, water stored in the ground and as snow and ice, and runoff. These physical hydrological processes show with respect to the fundamental knowledge about the process, its measurement and estimation and how it ties in with water quality. Following this is a section on analyzing streamflow data, including using computer models and combining hydrology and ecology for in-stream flow assessment. A chapter on water quality shows how to measure and estimate it in a variable environment and finishes with a section on pollution treatment. The final chapter brings the text together to discuss water resource management andreal-life issues that are faced by hydrologists in a constantly changing world. Fundamentals of Hydrology is a lively and accessible introduction to the study of hydrology at university level. This new edition continues to provide an understanding of hydrological processes, knowledge of the techniques used to assess water resources and an up-to-date overview of water resource management in a changing world. Throughout the text, wide-ranging examples and case studies are used to clearly explain ideas and methods.

Download or read book Fire on Earth written by Andrew C. Scott and published by John Wiley & Sons. This book was released on 2013-10-31 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earth is the only planet known to have fire. The reason is both simple and profound: fire exists because Earth is the only planet to possess life as we know it. Fire is an expression of life on Earth and an index of life’s history. Few processes are as integral, unique, or ancient. Fire on Earth puts fire in its rightful place as an integral part of the study of geology, biology, human history, physics, and global chemistry. Fire is ubiquitous in various forms throughout Earth, and belongs as part of formal inquiries about our world. In recent years fire literature has multiplied exponentially; dedicated journals exist and half a dozen international conferences are held annually. A host of formal sciences, or programs announcing interdisciplinary intentions, are willing to consider fire. Wildfire also appears routinely in media reporting. This full-colour text, containing over 250 illustrations of fire in all contexts, is designed to provide a synthesis of contemporary thinking; bringing together the most powerful concepts and disciplinary voices to examine, in an international setting, why planetary fire exists, how it works, and why it looks the way it does today. Students, lecturers, researchers and professionals interested in the physical, ecological and historical characteristics of fire will find this book, and accompanying web-based material, essential reading for undergraduate and postgraduate courses in all related disciplines, for general interest and for providing an interdisciplinary foundation for further study. A comprehensive approach to the history, behaviour and ecological effects of fire on earth Timely introduction to this important subject, with relevance for global climate change, biodiversity loss and the evolution of human culture. Provides a foundation for the interdisciplinary field of Fire Research Authored by an international team of leading experts in the field Associated website provides additional resources
