Download or read book Life of Inland Waters written by James G. Needham and published by Comstock Publishing Associates. This book was released on 2019-03-15 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work is a textbook of fresh-water life dealing with its forms, its conditions, its fitnesses, its associations, and its economic aspects. The ecologic side of fresh-water biology is emphasized. Due consideration is given to the educational, economic, sanitary, social, civic, and aesthetic aspects of the subject. Limnology in America today is in its infancy. The value of its past achievements is just beginning to be appreciated. The benefits to come from a more intensive study of water life arc just beginning to be disclosed. That there is a widespread interest is already manifest in the large number of biological stations at which limnological work is being done. We recommend this volume as a general introduction to all students and teachers of this subject.

Download or read book Perspectives in Urban Entomology written by G. W. Frankie and published by Academic Press. This book was released on 2013-09-17 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Perspectives in Urban Entomology is a collection of papers presented at the "Ecology and Management of Insect Populations in Urban Environments" held in Washington, D.C. in 1976. This collection deals with urban entomology with emphasis on insects, insect-plant relationships, and arthropods in the urban environments. One paper examines the causes why certain species manage to survive in an urban environment while others do not. The book cites one example—the Rothamsted insect survey—and analyzes the pressures of development in the surrounding land area. One paper addresses the educational and esthetic value of an insect-plant relationship in an ever expanding development of urban spaces. Another paper shows the value and benefit of a scientific investment in urban agriculture—defined as small-scale agriculture in urban areas—as contributing to food crops. Some papers also examine the use of insecticides and technology transfer in the management of urban pest control. This book will be valuable for entomologists, urban planners and developers, environmentalists, and for general readers residing in metropolitan areas.
