Book excerpt: Bachelor Thesis from the year 2015 in the subject Biology - Behaviour, South Eastern Kenya University, Kitui Campus, language: English, abstract: Termites are eusosial organisms that have a profile of destructive and menacing organisms that serve an insignificant role in Earth’s ecology complex system. In the semi arid parts of Kenya, they are thought to be the primary cause of vegetation denudation especially during the dry seasons. Even after several years of Biology advancement its uncouth how most people have failed to appreciate the incredible role this animal perform in their niche for the benefit of humanity, especially in the inhospitable arid and infertile environments. Moisture shortage and the elevated temperatures characterize these regions, which has discouraged the survival of many decomposers in this environment leaving only a few species that have adapted to the conditions to survive, notably several species of termites. Water is life; this truth is not lost on these creatures. Some species of termites have evolved to such a level that they have the abilities to forage over unusual long distances and partially control their own dwelling environments, through the construction of nests structures in such a way that humidity and temperature does not vary all seasons. Termites create ingenious nests (mounds) from their waste materials and soils through tightly packing every particle together, creating waterproof corridors. For this reason, many have termed them as soil engineers. The termites’ ability to digest cellulose gives them advantage over other soil macro decomposers. This is enhanced by their mutualistic coexistence with certain bacteria in their gut that enables them to digest cellulose, which is the main constituent of their diet. Overall, Termites are most active soil macro inverts dominating the decomposition process in arid and semi arid environment during the dry seasons.

Download or read book Management of Semi-arid Ecosystems written by Brian Harrison Walker and published by Elsevier Science & Technology. This book was released on 1979 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extensive regions of the world have a climate which, whilst permitting development of a continuous vegetative cover, is too dry for successful annual cropping. These are the semi-arid areas where land use is based on the natural vegetation. Easily degraded and difficult to maintain, they are under increasing pressure as expanding human populations move in and endeavour to force a living from them. As a result they contain some of the worst examples of resource degradation. This book examines the problems and opportunities involved in man's use of semi-arid areas. The authors are all actively involved in research and land management in the areas discussed. Each chapter begins with a detailed, up-to-date account of the ecology of the region (its climate, soils, vegetation, fauna and main ecological characteristics). This is followed by a history of land use, problems involved in its management, a review of current research and recommended land use practices. The common features of semi-arid ecosystems are brought together in a final section.

Available in PDF, EPUB and Kindle. Book excerpt: This Volume comprises 12 chapters in an attempt to bring available information on biology, social behavour and economic importance of termites. Chapters in this book dealing with termites identification provide a review on most updated information of their systematics. Ecologically, termites interact with living and non-living surroundings and deliver a wide range of behaviors. In a separate chapter termites ecology is examined and explored. Termites depend on their gut microbes for digestion of complex polysaccharides of wood into simpler molecules. Information provided on termite gut microbiome and lignocellulose degradation constitutes an important contribution. Termite biology and social behaviour have been addressed comprehensively. Trail pheromones are responsible for the orientation and recruitment of nestmates to the food sources. Once arriving at a potential food source, termites assess its quality using a different set of cues. A separate chapter on trail pheromones, cues used during foraging and food assessment, with preferences for foraging sites, contributes a wealth of information. Emphasis has been given on reviewing ecological benefits of termites in other chapters. The information with respect to termite species as an edible insect and the overall role it plays in food and nutrition security in Africa is quite informative. A separate chapter dealing with importance of termites and termitaria in mineral exploration constitutes a significant step in addressing the economic importance of this insect group.

This book was released on 1997 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In natural ecosystems, termites are typical ecosystem engineers and, in semi-arid ecosystems, often keystone species. It is thus likely that termites play a major beneficial role through promotion of essential ecological processes in agroecosystems in conflict with their well-established role as pests. This paper reviews the impacts of land clearing and preparation, cropping systems and management practices on termite diversity and activity. Current knowledge of the role of termites in agroecosystem function is discussed with reference to soil processes, vegetation cover, atmospheric gas exchanges and agricultural intensification. Methods for assessing termite diversity and function are outlined and priority research areas are suggested.

This book was released on 2010-10-20 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biology of Termites, a Modern Synthesis brings together the major advances in termite biology, phylogenetics, social evolution and biogeography. In this new volume, David Bignell, Yves Roisin and Nathan Lo have brought together leading experts on termite taxonomy, behaviour, genetics, caste differentiation, physiology, microbiology, mound architecture, biogeography and control. Very strong evolutionary and developmental themes run through the individual chapters, fed by new data streams from molecular sequencing, and for the first time it is possible to compare the social organisation of termites with that of the social Hymenoptera, focusing on caste determination, population genetics, cooperative behaviour, nest hygiene and symbioses with microorganisms. New chapters have been added on termite pheromones, termites as pests of agriculture and on destructive invasive species.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is the fifth in a series of publications produced over the last five years on the ecology of tropical savannas. The volumes arise from work undertaken by the Responses of Savannas to Stress and Disturbance (RSSD) Program, under the auspices of the International Union of Biological Sciences (IUBS) Decade of the Tropics Programme, co-sponsored by the UNESCO Man and the Biosphere (MAB) Program. Savannas cover just under one third of the world's land surface and contain a large and rapidly growing proportion of the world's population as well as the majority of its rangelands and livestock. Most savannas are experiencing increasing pressures from demographic and economic changes that have increased dramatically over the past few decades. In addition to the changing patterns in demography and economics, and the forecasts of global warming further alert us to the most important challenge - to conserve and manage wisely the savanna ecosystems of the world. It is this conservation that forms the basis of the work of the RSSD Program. This fifth publication is comprised of research papers presented at the RSSD's international symposium held in Darwin, Australia, in 1988. The papers address the Australian perspective and intercontinental comparisons and come from an international, expert authorship.

This book was released on 2012-12-06 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aerial photography has revealed the striking, widespread phenomenon of repeating patterns of vegetation in more arid areas of the world. Two interdependent phases, bands of dense and sparse vegetation, alternate in the landscape. This volume synthesizes half a century's accumulated knowledge of both theoretical and applied landscape function from a variety of these regions. It covers structure, dynamics, and methods of study, as well as disturbances to these landscapes and relevant management issues. Various chapters discuss the role of modeling in answering questions about the origins and complex processes of banded landscapes.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the full breadth of forest entomology. It combines the work of forest entomologists working on the impact and management of forest pests with those involved in diversity assessment and conservation of insects in forests. Forests and Insects demonstrates that both these disciplines demand an understanding of population and community biology. The book covers such topics as colonization of trees by insects, population dynamics of forest insects, insect natural enemies, the effects of climate change and pollution on forest pests, spatial variation in the abundance of insects,the mineralization of carbon by termites, the impact of herbivorous insects, and the conservation of forest insect diversity, including the effects of forest fragmentation and deforestation. This Royal Entomological Society Symposium volume will be of great interest to all agricultural and forest entomologists, population and community biologists, pest management specialists and anyone concerned with the conservation of forest biodiversity.

Available in PDF, EPUB and Kindle. Book excerpt: Insect Ecology: An Ecosystem Approach, Fifth Edition provides the most updated and comprehensive knowledge of the diversity of insect responses to environmental changes and their effects on ecosystem properties and services. Written by an expert in the field, this book addresses ways in which insect morphology, physiology and behavior tailor their adaptation to particular environmental conditions, how those adaptations affect their responses to environmental changes, and how their responses affect ecosystem properties and the ecosystem services on which humans depend for survival. This edition also addresses recent reports of global declines in insect abundance and how these declines could affect human interests. Insect Ecology: An Ecosystem Approach, Fifth Edition is an important resource for researchers, entomologists, ecologists, pest managers and conservationists who want to understand insect ecology and to manage insects in ways that sustain the delivery of ecosystem services. Graduate and advanced undergraduate students may also find this as a useful resource for entomology and specifically insect ecology courses. The only insect ecology text that emphasizes insect effects on ecosystem properties and services, as well as evolutionary adaptations to environmental conditions Includes new material on long-term trends in insect abundance, addressing the so-called “insect apocalypse Offers crucial updates on mechanisms by which insects affect, and potentially regulate, ecosystem structure and function Applies ecological principles to improved management of insects for the sustainable delivery of ecosystem services
