Download or read book 100 Butterflies and Moths written by Jeffrey C. Miller and published by Harvard University Press. This book was released on 2007 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Walking a forest trail in Costa Rica, a visitor might be struck by the sight of an iridescent blue morpho butterfly fluttering ahead in the filtered daylight, or an enormous silk moth, as magnificently patterned and subtly colored as a Persian carpet, only emerging to fly at night. Elsewhere, vivid yellow and orange sulphur butterflies flock to puddles to sip the concentrated minerals. Such is the dazzling variety of the butterflies and moths unique to this region. Gathered by biologists Daniel Janzen and Winifred Hallwachs in the forests of northwestern Costa Rica, 100 tropical butterflies and moths represent the diversity in large-format photographs by Jeffrey Miller that document the dizzying variety of shapes, colors, and markings. The photographs are accompanied by species accounts and images of the corresponding caterpillar. The authors recount these insects' feats of mimicry and migration, lift the veil on their courtship, and show how the new technology of DNA barcoding is changing the picture of Lepidopteran biodiversity. The authors also tell the success story of Area de Conservacion Guanacaste, where the long-term work of Janzen and Hallwachs, a team of caterpillar collectors, and the participation of neighboring farming communities has deepened understanding of Costa Rica's Lepidoptera and has brought about advances in restoration ecology of tropical habitats, biodiversity prospecting, biotechnology, and ecotourism development.

Download or read book For the Health of the Land written by Aldo Leopold and published by Island Press. This book was released on 2012-07-16 with total page 263 pages. Available in PDF, EPUB and Kindle. Book excerpt: Aldo Leopold's classic work A Sand County Almanac is widely regarded as one of the most influential conservation books of all time. In it, Leopold sets forth an eloquent plea for the development of a "land ethic" -- a belief that humans have a duty to interact with the soils, waters, plants, and animals that collectively comprise "the land" in ways that ensure their well-being and survival. For the Health of the Land, a new collection of rare and previously unpublished essays by Leopold, builds on that vision of ethical land use and develops the concept of "land health" and the practical measures landowners can take to sustain it. The writings are vintage Leopold -- clear, sensible, and provocative, sometimes humorous, often lyrical, and always inspiring. Joining them together are a wisdom and a passion that transcend the time and place of the author's life. The book offers a series of forty short pieces, arranged in seasonal "almanac" form, along with longer essays, arranged chronologically, which show the development of Leopold's approach to managing private lands for conservation ends. The final essay is a never before published work, left in pencil draft at his death, which proposes the concept of land health as an organizing principle for conservation. Also featured is an introduction by noted Leopold scholars J. Baird Callicott and Eric T. Freyfogle that provides a brief biography of Leopold and places the essays in the context of his life and work, and an afterword by conservation biologist Stanley A. Temple that comments on Leopold's ideas from the perspective of modern wildlife management. The book's conservation message and practical ideas are as relevant today as they were when first written over fifty years ago. For the Health of the Land represents a stunning new addition to the literary legacy of Aldo Leopold.
