Download or read book Quantitative Methods in Landscape Ecology written by Robert H. Gardner and published by Springer. This book was released on 1991 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Landscape ecology as a modern interdisciplinary science is making use increasingly of quantitative research techniques adopted from other fields. So far, no synthetic reference has been available to those wishing to acquaint themselves with new approaches to quantitative analysis of spatial heterogeneity at the landscape level. This book seeks to meet this need by providing a conceptual framework and illustrating potential applications for methods such as pattern analysis, spatial statistics, fractals modeling, broad-scale studies, and extrapolation across scales. Each technique is discussed in sufficient detail to be adaptable to a variety of research problems. Quantitative Methods in Landscape Ecology will be an important resource for researchers and students of landscape and ecosystem ecology in understanding and analyzing the dynamics of complex spatial systems."--
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.
Download or read book Southwood s Ecological Methods written by Peter A. Henderson and published by Oxford University Press. This book was released on 2021-04-01 with total page 624 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.

This book was released on 2021-08-24 with total page 356 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laboratory Methods for Soil Health Analysis Analyzing, comparing, and understanding soil health data The maintenance of healthy soil resources is instrumental to the success of an array of global efforts and initiatives. Whether they are working to combat food shortages, conserve our ecosystems, or mitigate the impact of climate change, researchers and agriculturalists the world over must be able to correctly examine and understand the complex nature of this essential resource. These new volumes have been designed to meet this need, addressing the many dimensions of soil health analysis in chapters that are concise, accessible and applicable to the tasks at hand. Soil Health, Volume Two: Laboratory Methods for Soil Health Analysis provides explanations of the best practices by which one may arrive at valuable, comparable data and incisive conclusions, and covers topics including: Sampling considerations and field evaluations Assessment and interpretation of soil-test biological activity Macro- and micronutrients in soil quality and health PLFA and EL-FAME indicators Offering a practical guide to collecting and understanding soil health data, this volume will be of great interest to all those working in agriculture, private sector businesses, non-governmental organizations (NGOs), academic-, state-, and federal-research projects, as well as state and federal soil conservation, water quality and other environmental programs.

Download or read book Biology of Earthworms written by Ayten Karaca and published by Springer Science & Business Media. This book was released on 2010-11-09 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Earthworms, which belong to the order Oligochaeta, comprise roughly 3,000 species grouped into five families. Earthworms have been called ‘ecosystem engineers’; much like human engineers, they change the structure of their environments. Earthworms are very versatile and are found in nearly all terrestrial ecosystems. They play an important role in forest and agricultural ecosystems. This Soil Biology volume describes the various facets of earthworms, such as their role in soil improvement, soil structure, and the biocontrol of soil-borne plant fungal diseases. Reviews discuss earthworms’ innate immune system, molecular markers to address various issues of earthworm ecology, earthworm population dynamics, and the influences of organic farming systems and tillage. Further topics include the characteristics of vermicompost, relationships between soil earthworms and enzymes, the role of spermathecae, copulatory behavior, and adjustment of the donated sperm volume.
