The Scientific Bases for the Preservation of the Hawaiian Crow available in PDF, EPUB and Kindle. The Hawaiian Crow, or 'Alala, once an inhabitant of large forested areas of Hawaii, is now found only in the wild in a relatively small area of the central Kona coast. The decline of the 'Alala is part of a larger phenomenon of reduction and extinction of forest birds throughout Polynesia that has been associated with human colonization. It is a symptom of underlying ecological problems. In this book, a committee of experts in ornithology, captive propagation, conservation biology, population genetics, and ecology analyzes existing data about the 'Alala and details its findings, conclusions, and recommendations concerning recovery efforts for this endangered bird.

This book was released on 1997-03-21. The Scientific Bases for Preservation of the Mariana Crow available in PDF, EPUB and Kindle. This book, while focusing on current preservation challenges posed by the Aga, or Mariana crow, also reflects the larger issues and challenges of biodiversity conservation in all oceanic island ecosystems. It evaluates causes for the continuing decline of the Aga, which exists on only the two southernmost islands in the Mariana archipelago, Guam and Rota, and reviews actions to halt or reverse the decrease. This book reminds us of the importance and challenge of preserving the unique environmental heritage of islands of the Mariana archipelago, the need for increased knowledge to restore and maintain native species and habitats, and the compelling and lasting value of extensive public education to stimulate environmentally informed public policy development.

Download and read online ebook Our Common Journey write by National Research Council. This book was released on 1999-12-09. Our Common Journey available in PDF, EPUB and Kindle. World human population is expected to reach upwards of 9 billion by 2050 and then level off over the next half-century. How can the transition to a stabilizing population also be a transition to sustainability? How can science and technology help to ensure that human needs are met while the planet's environment is nurtured and restored? Our Common Journey examines these momentous questions to draw strategic connections between scientific research, technological development, and societies' efforts to achieve environmentally sustainable improvements in human well being. The book argues that societies should approach sustainable development not as a destination but as an ongoing, adaptive learning process. Speaking to the next two generations, it proposes a strategy for using scientific and technical knowledge to better inform future action in the areas of fertility reduction, urban systems, agricultural production, energy and materials use, ecosystem restoration and biodiversity conservation, and suggests an approach for building a new research agenda for sustainability science. Our Common Journey documents large-scale historical currents of social and environmental change and reviews methods for "what if" analysis of possible future development pathways and their implications for sustainability. The book also identifies the greatest threats to sustainabilityâ€"in areas such as human settlements, agriculture, industry, and energyâ€"and explores the most promising opportunities for circumventing or mitigating these threats. It goes on to discuss what indicators of change, from children's birth-weights to atmosphere chemistry, will be most useful in monitoring a transition to sustainability.

Osborn. This book was released on 2024-05-02. Feather Trails available in PDF, EPUB and Kindle. The story of one woman’s remarkable work with a trio of charismatic, endangered bird species—and her discoveries about the devastating threats that imperil them. In Feather Trails, wildlife biologist and birder Sophie A. H. Osborn reveals how the harmful environmental choices we’ve made—including pesticide use, the introduction of invasive species, lead poisoning, and habitat destruction—have decimated Peregrine Falcons, Hawaiian Crows, and California Condors. In the Rocky Mountains, the cloud forests of Hawai’i, and the Grand Canyon, Sophie and her colleagues work day-to-day to try to reintroduce these birds to the wild, even when it seems that the odds are steeply stacked against their survival. With humor and suspense, Feather Trails introduces us to the fascinating behaviors and unique personalities of Sophie’s avian charges and shows that what endangers them ultimately threatens all life on our planet. More than a deeply researched environmental investigation, Feather Trails is also a personal journey and human story, in which Sophie overcomes her own obstacles—among them heat exhaustion, poachers, rattlesnakes, and chauvinism. Ultimately, Feather Trails is an inspiring, poignant narrative about endangered birds and how our choices can help to ensure a future not only for the rarest species, but for us too. "An intimate look at the wonder and effort needed for working with endangered species in the wild. [Osborn's] matter-of-fact writing style and wry humor make the reader part of the action."—Booklist (starred review)
