The Chattahoochee River Basin research in Georgia analyzed changes in water quality variables between 1985 and 2000 since the riparian buffers legislation was engaged in 1989. The Chattahoochee River itself is a nationally recognized drinking water supply for residents in the metropolitan Atlanta region. The four water quality variables investigated in the research were fecal coliform, dissolved oxygen, nitrites, and phosphorus. The water quality variable levels were compared to the drinki...

The history behind our growing water crisis: "A gem . . . An erudite romp through two millennia of water and sanitation practice and technology." — NatureTurn on the faucet, and water pours out. Pull out the drain plug, and the dirty water disappears. Most of us give little thought to the hidden systems that bring us water and take it away when we're done with it. But these underappreciated marvels of engineering face an array of challenges that cannot be s...

An introduction to insect physiology, genetics and behaviour which looks at the interaction between humans and insects, and explores both the positive and negative aspects of the relationship.

Parasites have evolved independently in numerous animal lineages, and they now make up a considerable proportion of the biodiversity of life. Not only do they impact humans and other animals in fundamental ways, but in recent years they have become a powerful model system for the study of ecology and evolution, with practical applications in disease prevention. Here, in a thoroughly revised and updated edition of his influential earlier work, Robert Poulin provides an evolutionary ecologis...

Integrated Pest Management (IPM) is an effective and environmentally sensitive approach to pest management. It uses natural predators, pest-resistant plants, and other methods to preserve a healthy environment in an effort to decrease reliance on harmful pesticides. Featuring forty chapters written by leading experts, this textbook covers a broad and comprehensive range of topics in integrated pest management, focused primarily on theory and concepts. It is complemented by two award winnin...

This is one of ten eBooks on the commercial production of ornamental fish. It is based predominantly on the author's 30 years of experience, mostly on his own farms. While a few of the eBooks are purely commercial, others, particularly those on breeding, will also be helpful to hobbyists, understandable even by beginners. The following description is provided as a guide. Includes such aspects as water availability and suitability, terrain suitability, energy and communication, statutory co...

Restoring Disturbed Landscapes is a hands-on guide for individuals and groups seeking to improve the functional capacity of landscapes. The book presents a five-step, adaptive procedure for restoring landscapes that is supported by proven principles and concepts of ecological science.Written by restoration experts with a wealth of experience teaching restoration principles and techniques to practitioners and would-be practitioners from a variety of backgrounds, the book of...

This antiquarian volume contains an accessible and concise guide to pruning, with information on the correct methods for pruning rose trees, fruit trees, ornamental trees and shrubs, and many other plants commonly found in the garden. Written in simple, clear language and profusely illustrated, this text will be of considerable utility to anyone with an interest in gardening, and it would make for a great addition to collections of gardening literature. Although old, the information contai...

As humans have come to dominate the earth, the ideal of studying and teaching ecology in pristine ecosystems has become impossible to achieve. Our planet is now a mosaic of ecosystems ranging from the relatively undisturbed to the completely built, with the majority of people living in urban environments. This accessible introduction to the principles of urban ecology provides students with the tools they need to understand these increasingly important urban ecosystems. It builds upon the ...

Often growing far above the ground, "air plants" (or epiphytes) defy many of our common perceptions about plants. The majority use their roots only for attachment in the crowns of larger, usually woody plants—or to objects such as rocks and buildings—and derive moisture and nutrients from the atmosphere and by collecting falling debris. Only the mistletoes are true parasites. Epiphytes are not anomalies and there are approximately 28,000 species—about 10 percent of the hig...

This new, fully updated and revised edition of Improved Grassland Management covers all aspects of grassland management and is of particular relevance to the UK and the Republic of Ireland, although the principles discussed apply to all temperate grassland zones. Almost twenty years ago, when the original edition of this book was written by John Frame, issues such as efficiency in the use of nutrients in manures, grassland biodiversity and greenhouse gas emissions from ruminant production ...

This practical handbook describes sampling and laboratory assessment methods for the biodiversity of a number of key functional groups of soil organisms, including insects, earthworms, nematodes, fungi and bacteria. The methods have been assembled and the protocols drafted by a number of scientists associated with the UNEP-GEF funded Conservation and Sustainable Management of Below-Ground Biodiversity Project, executed by the Tropical Soil Biology and Fertility (TSBF) Institute of the Inte...
