Download or read book Biodiversity Conservation in Costa Rica written by Gordon W. Frankie and published by Univ of California Press. This book was released on 2004-02-06 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The beautiful tropical dry forest of northwest Costa Rica, with its highly seasonal rainfall and diversely vegetated landscape, is disappearing even more rapidly than Costa Rica's better-known rain forest, primarily because it has been easier to convert to agriculture. This book, based on more than thirty years of study, offers the first comprehensive look at the ecology, biodiversity, and conservation status of this endangered and fragile region. The contributors, from Costa Rica, Britain, Mexico, and the United States, and representing the fields of ecology, environmental education, policy, and the law, examine the major plant and animal groups living in the dry forest and present the first technical evaluation of Costa Rica's conservation efforts. As they assess the status of their area of specialty in the dry forest, the contributors also look beyond this particular region to show how its plants and animals are ecologically and evolutionarily connected to other geographic areas in Costa Rica and Central America. Their chapters cover topics such as watershed and coastal management, plant phenology, pollination, insects, birds, mammals, amphibians, and reptiles. They also consider the socioeconomic, policy, legal, and political aspects of biodiversity conservation, giving the volume a wide-ranging perspective and making a unique contribution to our knowledge of the tropical dry forest. The book concludes with an important synthesis of the contributors' recommendations on future directions, policies, and actions that will better conserve biodiversity in Costa Rica and other neotropical forests as well.
Download or read book Phenology An Integrative Environmental Science written by Mark D. Schwartz and published by Springer Science & Business Media. This book was released on 2011-04-28 with total page 567 pages. Available in PDF, EPUB and Kindle. Book excerpt: Phenology is the study of plant and animal life cycle events, which are triggered by environmental changes, especially temperature. Wide ranges of phenomena are included, from first openings of leaf and flower buds, to insect hatchings and return of birds. Each one gives a ready measure of the environment as viewed by the associated organism. Thus, phenological events are ideal indicators of the impact of local and global changes in weather and climate on the earth's biosphere. Assessing our changing world is a complex task that requires close cooperation from experts in biology, climatology, ecology, geography, oceanography, remote sensing and other areas. This book is a synthesis of current phenological knowledge, designed as a primer on the field for global change and general scientists, students and interested members of the public. With contributions from a diverse group of over fifty phenological experts, covering data collection, current research, methods and applications, it demonstrates the accomplishments and potential of phenology as an integrative environmental science.

Available in PDF, EPUB and Kindle. Book excerpt: Most people know of aphids as garden pests, infesting the soft green tissues of plants in vast numbers and killing them by sucking out the sap. Indeed, among the 4000 or so known species of aphids about 250 are pests, and in temperate regions several are economically important agricultural pests that damage crops directly during feeding or act as v
