Available in PDF, EPUB and Kindle. Book excerpt: Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the milligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques find their way into the classroom when the problems involved have been suffi ciently ironed out to permit students to master the manipulations in a few lab oratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomo logical problems, and (3) to describe experiments which may be applicable for use in biology laboratory co~rses.

Download or read book Planted Forests Contributions to the Quest for Sustainable Societies written by James Reid Boyle and published by Springer Science & Business Media. This book was released on 1999-07-31 with total page 486 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume, international experts describe biological, ecological, economic and social aspects of planted forests. Representative types of planted forests are described and discussed, technical and social aspects are considered, and case studies depict the variety of purposes and uses of planted forests. Authors discuss the nature of planted forests of representative species world-wide, basic biology and ecology of plantations, and economic and social considerations in landscapes where planted forests contribute to potentially sustainable societies. The authors represent temperate and tropical forests, developed and developing nations, and all levels of intensity of planting and managing forest trees. This compilation of views and viewpoints about planted forests provides a fresh, broad outlook on trees planted for myriad purposes. Forest scientists and managers, policy experts, development officials and interested citizens will find information of value and stimuli for thinking about forestsof the future.

Download or read book Practical Methods in Ecology written by Peter A. Henderson and published by John Wiley & Sons. This book was released on 2009-04-13 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: There are few books available that provide a good introduction tothe methods and techniques for ecological research. This book willbe invaluable to lecturers teaching field courses and studentsundertaking project work in ecology. Each chapter will focus on an ecological technique. It will havean introductory section that describes the ecological principlesand theory. This will then be followed by example applications.These will focus on three most common habitats where teachers takestudents for fieldwork; the seashore, ponds and lakes, fields andwoodland. Gives specific worked examples from the main ecosystems usedfor undergraduate study - seashore, lakes/ponds, field andwoodland. Only introductory text specifically focused on fieldtechniques. Great 'how-to' guide that will show student exactly how tocarry out each method. Only text to emphasise the principles behind the techniques -taking a methods based approach rather than a taxonomic approach(eg chapters split into population measures, biodiversity measures,species richness measures rather than methods for invertebrates,methods for mammals, methods for birds etc). Greater emphasis on the equipment involved - how to make it,where to buy it. Good references to further reading and advancedtechniques.
