Download or read book Parrots written by Mike Parr and published by A&C Black. This book was released on 2010-07-30 with total page 586 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first book created primarily for the field identification of parrots, one of the most familiar and colorful groups of birds. From the mighty. macaws to the diminutive pygmy parrots, the 350 species of parrots include cockatoos, parakeets, lovebirds, and Budgerigar. Most are brightly colored or even gaudy, but a few are drab, and some are nocturnal and flightess. Parrots, found throughout most of the warmer regions of the world, occur in greatest numbers in Australasian and South America. This book includes 88 superb color illustrations of every species and most identifiable subspecies of parrot, as well as range maps of their locations. It offers many firsthand insights into the ecology of each species, vocalizations, life cycle characteristics, and geographical variation. It also provides up-to-date information on the conservation status of those species of parrots that are threatened or endangered.

Download or read book Environment Concerns in Rights of Way Management 8th International Symposium written by John W. Goodrich-Mahoney and published by Elsevier. This book was released on 2011-08-11 with total page 873 pages. Available in PDF, EPUB and Kindle. Book excerpt: The management of rights-of-way by electric and telephone utilities, highway departments, gas pipeline companies, and railroads around the world is guided and constrained by policies and regulations to protect the environment. Companies that manage rights-of-way are required to comply with these regulations, and are seeking the most cost-effective management practices that, at the same time, demonstrate stewardship of the environment. Protection of biodiversity and sustainable development are especially important as national goals in many countries, and rights-of-way managers are seeking practical ways to include public participation in their operations. * Addresses environmental issues in rights-of-way planning and management * Provides a forum for information exchange among various agencies, industries, environmental consultants, and academic organizations * Presents peer-reviewed papers to help achieve a better understanding of current environmental issues involved in rights-of-way management

Download or read book Biological Invasions Theory and Practice written by Nanako Shigesada and published by Oxford University Press, UK. This book was released on 1997-02-06 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with the ecological effect a species can have when it moves into an environment that it has not previously occupied (commonly referred to as an 'Invasion'). It is unique in presenting a clear and accessible introduction to a highly complex area - the modelling of biological invasions. The book presents the latest theories and models developed from studies into this crucial area. It includes data and examples from biological case studies showing how the models can be applied to the study of invasions, whether dealing with AIDS, the European rabbit, or prickly pear cactuses. - ;In nature, all organisms migrate or disperse to some extent, either by walking, swimming, flying, or being transported by wind or water. When a species succeeds in colonising an area that it has not previously inhabited, this is referred to as an `invasion'. Humans can precipitate biological invasions often spreading disease or pests by their travels around the world. Using the large amount of data that has been collected from studies worldwide, ranging from pest control to epidemiology, it has been possible to construct mathematical models that can predict which species will become an invader, what kind of habitat is susceptible to invasion by a particular species, and how fast an invasion will spread if it occurs. This book presents a clear and accessible introduction to this highly complex area. Included are data and examples from biological case studies showing how these models can be applied to the study of invasions, whether dealing with AIDS, the European rabbit, or prickly pear cactuses. -
