Book Synopsis A Handbook of Field Methods for Research on Rice Stem-borers and Their Natural Enemies by : T. Nishida
Download or read book A Handbook of Field Methods for Research on Rice Stem-borers and Their Natural Enemies written by T. Nishida and published by Blackwell Scientific Publications Limited. This book was released on 1970 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: The population of many Asian countries are dependent on rice for their staple diet and therefore any insight into the ecology of rice stem-borers and their natural enemies would not only be of scientific interest, but also of considerable economic value. This handbook presents some of the methods that might prove useful in carrying out such research, and thus makes it possible to speed up the progress of research on the insects in question in sub-tropical and tropical rice-growing areas.

Book Synopsis A Technical Manual for Parasitic Weed Research and Extension by : J. Kroschel
Download or read book A Technical Manual for Parasitic Weed Research and Extension written by J. Kroschel and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 285 pages. Available in PDF, EPUB and Kindle. Book excerpt: Parasitic weeds of the families Cuscutaceae, Orobanchaceae and Scrophulariaceae are considered to be among the major problems facing agriculture in the Tropics and Subtropics. In the last decades, enormous efforts have been made and success achieved by scientists all over the world in gaining a better understanding of their biology and ecology as well as of control methods. However, no substantial reduction of infestation has been achieved in the past and control strategies specific to the different parasites, crops and farming systems must be further developed or adapted and realised among a wider farming population with suitable extension methods. This `Technical Manual' provides up-to-date methodologies for various aspects of research and extension related to parasitic weed species of the genera Striga, Alectra, Orobanche and Cuscuta. It has the intention to support scientists and extension workers of international and national research and extension institutes and universities, who are either new to the subject or plan to apply further techniques they are not yet familiar with.

Book Synopsis Ecological Methods by : T.R. Southwood
Download or read book Ecological Methods written by T.R. Southwood and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 548 pages. 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.

Book Synopsis Ecology and Biogeography in Sri Lanka by : C.H. Fernando
Download or read book Ecology and Biogeography in Sri Lanka written by C.H. Fernando and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 511 pages. Available in PDF, EPUB and Kindle. Book excerpt: When the late Professor Joachim Illies suggested in 1980 that I edit a volume of the Monographiae Biologicae on Sri Lanka, I was glad to accept the challenge. Although I had spent only six years of my research and teaching career in Sri Lanka, I had made personal contact or corresponded with many scientists who had worked in, still work in, or who have studied material from Sri Lanka. The present domicile of the authors of the chapters in this volume shows the wide geographic spread of interest in Sri Lanka, and indicates also the dispersion of Sri Lankan scientists like myself. Sri Lanka has had a relatively long history of indigenous scientific research in the natural sciences. From the early work of Kelaart (1852, Prodromous Fauna Zeylanicae, Ceylon Govt. Press, 250 pp.) to the present time, there has been a more or less sustained research effort in the natural sciences. The Colombo Museum, which celebrated its centenary only a few years ago, and the world famous Peradeniya Botanical Gardens, served as repositories and bases for continued research on the fauna and flora. There are a number of land marks in these studies.
