Download or read book Bird Census Techniques written by Colin J. Bibby and published by Academic Press. This book was released on 2012-12-02 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild birds are counted for a wide variety of reasons and by a bewildering array of methods. However, detailed descriptions of the techniques used and the rationale adopted are scattered in the literature, and the newcomer to bird census work or the experienced bird counter in search of a wider view, may well have difficulty in coming to grips with the subject as a whole. While not an end in itself, numerical and distributional census work is a fundamental part of many scientific and conservation studies, and one in which the application of given standards is vital if results are not to be distorted or applied in a misleading way.This book provides a concise guide to the various census techniques and to the opportunities and pitfalls which each entails. The common methods are described in detail, and illustrated through an abundance of diagrams showing examples of actual and theoretical census studies. Anyone with a bird census job to plan should be able to select the method best suited to the study at hand, and to apply it to best effect within the limits inherent in it and the constraints of the particular study.The Royal Society for the Protection of Birds and the British Trust for Ornithology have for many years pioneered the collaboration of amateurs and professionals in various census studies. Three members of their staff, each with extensive field experience, now pool the knowledge of these investigations to lay the groundwork for sound census work in future years.

Download or read book Sedge Cyperaceae Genera of Africa and Madagascar written by Jane Browning and published by Troubador Publishing Ltd. This book was released on 2017-05-16 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sedges (of the plant family Cyperaceae) can appear seemingly insignificant. On closer inspection, however, their hidden, complex and remarkable constructive design is revealed. In order to facilitate identification of the 63 genera occurring in Africa and Madagascar, this book includes, for the first time, photographs of the living sedge plants in their natural habitats and line drawings of their morphology. Additionally, photographs of small fruits, as they appear under a microscope, are included as well as full botanical descriptions, so that a detailed assessment of these plants is possible. The genera illustrated and accounted for here, carry the names that were applied at the turn of the century. Most of these names are still in use today, however, due to recent and on-going research there have been changes, not only to genera, but also to species within these genera. A list of these name changes is included so that the work is fully up to date at this time. Sedges are widely distributed in a number of diverse habitats (most often found in wetlands and on the margins of lakes, rivers and streams). This publication focuses on those genera occurring in Africa and Madagascar, however, as these plants are also represented on other continents, the taxonomic tools for identification presented here will be useful to those further afield. Beyond this, this book provides a window to the beauty of these often overlooked, but exquisite, plants.
Download or read book Aquatic Plants in Britain and Ireland written by C. D. Preston and published by BRILL. This book was released on 2022-06-13 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past 50 years, major changes have taken place in the distribution of aquatic plants in Europe. Many species have declined whilst other species have increased in abundance or spread, including several that were originally introduced from the New World. Despite the relative richness of the aquatic flora of Britain and Ireland, it is a neglected area of study. This book is not an identification manual but provides a summary of the distribution, habitat and reproductive biology of 200 taxa in 72 genera, with individual distribution maps, and also summarizes their distribution overseas. A joint project of I.T.E. (now C.E.H.), the Joint Nature Conservation Committee and the Environment Agency.

Download or read book World Checklist of Cyperaceae written by Rafaël Govaerts and published by Royal Botanic Gardens Kew. This book was released on 2007-01 with total page 765 pages. Available in PDF, EPUB and Kindle. Book excerpt: The sedge family, Cyperaceae, is the third largest family of monocotyledonous plants. They are of significant economic importance, especially among rural communities in the tropics, where sedges are intensively used. The World Checklist of Cyperaceae provides a single source guide to the correct names of all sedges, the source of their publication and indicating which names are currently accepted and which are synonyms. It will be a standard nomenclatural reference for further research into this important family. This makes it an invaluable reference for agriculturists, horticulturists, ecologists, conservationists and plant biologists.

Download or read book Ordination of Plant Communities written by R.H. Whittaker and published by Springer. This book was released on 1978 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: A large part of ecological research depends on use of two ap proaches to synthesizing information about natural communities: classification of communities (or samples representing these) into groups, and ordination (or arrangement) of samples in relation to environmental variables. A book published in 1973, 'Ordination and Classification of Communities,' sought to provide, through contributions by an international panel of authors, a coherent treatise on these methods. The book appeared then as Volume 5 of the Handbook of Vegetation Science, for which R. TuxEN is general editor. The desire to make this work more widely available in a less expensive form is one of the reasons for this second edition separating the articles on ordinction and on classification into two volumes. The other reason is the rapid advancement of understanding in the area of indirect ordination-mathematical techniques that seek to use measurements of samples from natural communities to produce arrangements that reveal environmental relationships of these communities. Such is the rate of change in this area that the last chapter on ordination in the first edition is already, 4 or 5 years after it was written, out of date; and new techniques of indirect ordination that could only be mentioned as possibilities in the first edition are becoming prominent in the field. In preparing the second edition the chapter on evaluation of ordinations has been rewritten, a new chapter on recent developments in continuous multivariate techniques has been included, and references to recent work have been added to other chapters.
Download or read book Ethnobotany written by C. M. Cotton and published by Wiley. This book was released on 1996-08-06 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in ethnobotany has increased dramatically in recent years. The search for new medicines by the pharmaceutical industry has turned to plant natural products and to ethnobotanical studies as a first step in bioprospecting. These studies are making a valuable contribution to the cataloguing of biological diversity and hence to the conservation of endangered ecosystems and the human societies which depend upon them. Discussing traditional methods of plant management as well as plant use, this textbook is an authoritative and fascinating introduction to this exciting area of plant biology. Citing examples from throughout the world and drawing on a wide range of source materials, the author describes the history of the interactions between plants and people and the concepts, methodology and future direction of ethnobotanical study. Capturing current interest in traditional medicine, as well as the potential for exciting new drug discoveries, Ethnobotany: Principles and Applications is an informative, stimulating and timely text which includes an extensive bibliography.
Download or read book Bound Lives written by Rachel Sarah O'Toole and published by University of Pittsburgh Pre. This book was released on 2012-04-15 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bound Lives chronicles the lived experience of race relations in northern coastal Peru during the colonial era. Rachel Sarah O'Toole examines how Andeans and Africans negotiated and employed casta, and in doing so, constructed these racial categories. Royal and viceregal authorities separated "Indians" from "blacks" by defining each to specific labor demands. Casta categories did the work of race, yet, not all casta categories did the same type of work since Andeans, Africans, and their descendants were bound by their locations within colonialism and slavery. The secular colonial legal system clearly favored indigenous populations. Andeans were afforded greater protections as "threatened" native vassals. Despite this, in the 1640s during the rise of sugar production, Andeans were driven from their assigned colonial towns and communal property by a land privatization program. Andeans did not disappear, however; they worked as artisans, muleteers, and laborers for hire. By the late seventeenth and early eighteenth centuries, Andeans employed their legal status as Indians to defend their prerogatives to political representation that included the policing of Africans. As rural slaves, Africans often found themselves outside the bounds of secular law and subject to the judgments of local slaveholding authorities. Africans therefore developed a rhetoric of valuation within the market and claimed new kinships to protect themselves in disputes with their captors and in slave-trading negotiations. Africans countered slaveholders' claims on their time, overt supervision of their labor, and control of their rest moments by invoking customary practices. Bound Lives offers an entirely new perspective on racial identities in colonial Peru. It highlights the tenuous interactions of colonial authorities, indigenous communities, and enslaved populations and shows how the interplay between colonial law and daily practice shaped the nature of colonialism and slavery.
