Download or read book Transgenesis and the Management of Vector Borne Disease written by Serap Aksoy and published by Springer Science & Business Media. This book was released on 2008-08-21 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic, bacterial and viral agents continue to challenge the welfare of humans, livestock, wild life and plants worldwide. The public health impact and financial consequences of these diseases are particularly hard on the already overburdened economies of developing countries especially in the tropics. Many of these disease agents utilize insect hosts (vectors) to achieve their transmission to mammals. In the past, these diseases were largely controlled by insecticide-based vector reduction strategies. Now, many of these diseases have reemerged in the tropics, recolonizing their previous range, and expanding into new territories previously not considered to be endemic. Habitat change, irrigation practices, atmospheric and climate change, insecticide and drug resistance as well as increases in global tourism, human traffic and commercial activities, have driven the reemergence and spread of vector borne diseases. While these diseases can be controlled through interventions aimed at both their vertebrate and invertebrate hosts, no effective vaccines exist, and only limited therapeutic prospects are available for their control in mammalian hosts. Molecular technologies such as transgenesis, which is the subject of this book, stand to increase the toolbox and benefit disease management strategies.
Download or read book Southwood s Ecological Methods written by Peter A. Henderson and published by Oxford University Press. This book was released on 2021 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Methods by the late T.R. E. Southwood and revised over the years by P. A. Henderson has developed into a classic reference work for the field biologist. It provides a handbook of ecological methods and analytical techniques pertinent to the study of animals, with an emphasis on non-microscopic animals in both terrestrial and aquatic environments. It remains unique in the breadth of the methods presented and in the depth of the literature cited, stretching right back to the earliest days of ecological research. The universal availability of R as an open source package has radically changed the way ecologists analyse their data. In response, Southwood's classic text has been thoroughly revised to be more relevant and useful to a new generation of ecologists, making the vast resource of R packages more readily available to the wider ecological community. By focusing on the use of R for data analysis, supported by worked examples, the book is now more accessible than previous editions to students requiring support and ideas for their projects. Southwood's Ecological Methods provides a crucial resource for both graduate students and research scientists in applied ecology, wildlife ecology, fisheries, agriculture, conservation biology, and habitat ecology. It will also be useful to the many professional ecologists, wildlife biologists, conservation biologists and practitioners requiring an authoritative overview of ecological methodology.

Available in PDF, EPUB and Kindle. Book excerpt: The virtual impossibility of extracting the many different species from a habitat with equal efficiency by a single method (e.g. Nef, 1960). 1.1 Population estimates Population estimates can be classified into a number of different types; the most convenient classification is that adopted by Morris (1955), although he used the terms somewhat differently in a later paper (1960). 1.1.1 Absolute and related estimates The animal numbers may be expressed as a density per unit area of the ground of the habitat. Such estimates are given by nearest neighbour and related techniques (Chapter 2), marking and recapture (Chapter 3), by sampling a known fraction of the habitat (Chapter 4-6) and by removal sampling and random walk techniques (Chapter 7). Absolute population The number of animals per unit area (e.g. hectare, acre). It is almost impossible to construct a budget or to study mortality factors without the conversion of population estimates to absolute figures, for not only do insects often move from the plant to the soil at different developmental stages, but the amount of plant material is itself always changing. The importance of obtaining absolute estimates cannot be overemphasized.

Available in PDF, EPUB and Kindle. Book excerpt: This classic text, whose First Edition one reviewer referred to as"the ecologists' bible," has been substantially revised andrewritten. Not only have the advances made in the field since theSecond Edition been taken into account, but the scope has beenexplicitly extended to all macroscopic animals, with particularattention being paid to fish as well as other vertebrates. Ecological Methods provides a unique synthesis of themethods and techniques available for the study of populations andecosystems. Techniques used to obtain both absolute and relativepopulation estimates are described, and approaches to the directmeasurement of births, deaths, migration and the construction andinterpretation of life tables are reviewed. The text is extensively illustrated, clearly describing a widerange of equipment and methods of analysis. Comprehensive andup-to-date bibliographies to each chapter fully cover the relevantliterature, and references are given to available computer programsand internet addresses. The book has an active web site providingadditional illustrations, details of equipment and programs, andreferences to work published since the revision was completed. Likethe earlier editions, this book will be an indispensable source ofreference to researchers and students at all levels in the fieldsof ecology, entomology and zoology. Completely revised and rewritten edition of a classic. Scope extended to all macroscopic animals, notably fish andother vertebrates. Active web site displaying additional material. References to computer programmes and internet addressesthroughout the text. Affordable paperback.
Download or read book Medical Insects and Arachnids written by R.P. Lane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 733 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surprising though it seems, the world faces almost as great a threat today from arthropod-borne diseases as it did in the heady days of the 1950s when global eradication of such diseases by eliminating their vectors with synthetic insecticides, particularly DDT, seemed a real possibility. Malaria, for example, still causes tremendous morbidity and mortality throughout the world, especially in Africa. Knowledge of the biology of insect and arachnid disease vectors is arguably more important now than it has ever been. Biological research directed at the development of better methods of control becomes even more important in the light of the partial failure of many control schemes that are based on insecticide- although not all is gloom, since basic biological studies have contributed enormously to the outstanding success of international control programmes such as the vast Onchocerciasis Control Programme in West Africa. It is a sine qua non for proper understanding of the epidemiology and successful vector control of any human disease transmitted by an arthropod that all concerned with the problem - medical entomologist, parasitologist, field technician - have a good basic understanding of the arthropod's biology. Knowledge will be needed not only of its direct relationship to any parasite or pathogen that it transmits but also of its structure, its life history and its behaviour - in short, its natural history. Above all, it will be necessary to be sure that it is correctly identified.

Download or read book Ecology of Insect Vector Populations written by R. C. Muirhead-Thomson and published by Elsevier. This book was released on 2013-09-17 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecology of Insect Vector Populations provides a review and appraisal of the ecology of insect vectors of disease, with particular attention to the problems of sampling adult insect vector populations. The book examines the manner in which the inter-related problems of insect ecology, behavior, and population sampling have been explored over a wide range of investigations on disease vectors. The text focuses mainly on the study of blood-sucking dipterous insects such as tse-tse flies, mosquitoes, black-flies, and midges along with the appraisal of relevant studies on house-fly and blow-fly populations. The studies of the ecology of the wingless vectors of disease or plague such as the fleas are carried out extensively. The dissertation will be of interest to medical entomologists, animal ecologists, and epidemiologists.
Download or read book International Review of General and Experimental Zoology written by William J. L. Felts and published by Academic Press. This book was released on 2013-10-22 with total page 460 pages. Available in PDF, EPUB and Kindle. Book excerpt: International Review of General and Experimental Zoology, Volume 1 is a collection of world literature concerning developments in general and experimental zoology. This book is composed of 9 chapters, and begins with an overview of foraminiferal biology. Foraminifera are single-cell animals, which extrude granuloreticulose pseudopodia and construct monothalamous or polythalamous shells of an organic, arenaceous, or calcareous nature. The succeeding chapters explore the significance of life span in biting insects, and the optic and static components of equilibrium orientation in fish, as well as their evaluation in the central nervous system. These topics are followed by discussions on environment and reproduction in domesticated species; experimental, histochemical, and ultrastructural studies of mammalian pituitary function; and the reproductive biology of strepsirhine. The final chapters examine the phylogenesis of vertebrate mineralized tissues and the effect of chronic exposure to increased gravity on growth and form of animals. This book will prove useful to zoologists.

Download or read book Biology of Blood Sucking Insects written by Mike Lehane and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood-sucking insects are the vectors of many of the most debilitating parasites of man and his domesticated animals. In addition they are of considerable direct cost to the agricultural industry through losses in milk and meat yields, and through damage to hides and wool, etc. So, not surprisingly, many books of medical and veterinary entomology have been written. Most of these texts are organized taxonomically giving the details of the life-cycles, bionomics, relationship to disease and economic importance of each of the insect groups in turn. I have taken a different approach. This book is topic led and aims to discuss the biological themes which are common in the lives of blood-sucking insects. To do this I have concentrated on those aspects of the biology of these fascinating insects which have been clearly modified in some way to suit the blood-sucking habit. For example, I have discussed feeding and digestion in some detail because feeding on blood presents insects with special problems, but I have not discussed respiration because it is not affected in any particular way by haematophagy. Naturally there is a subjective element in the choice of topics for discussion and the weight given to each. I hope that I have not let my enthusiasm for particular subjects get the better of me on too many occasions and that the subject material achieves an overall balance.
