Neotropical Savannas and Seasonally Dry Forests

Book Description
More often than not, when people think of a neotropical forest, what comes to mind is a rain forest, rather than a dry forest. Just as typically, when they imagine a savanna, they visualize the African plains, rather than those dry woodlands and grasslands found in the Neotropics. These same preconceptions can be found among scientists, as these ne

Author: The Endemism of the Vascular Flora of Mexico Present in Comarca Lagunera, an Agricultural Region in the Chihuahuan Desert

Book Description
A study of the distribution of 321 taxa of endemic vascular plants of Mexico distributed in Comarca Lagunera, a region of northern central Mexico within the Chihuahuan Desert, was conducted. The analysis consisted in detecting the areas of high richness and with this information propose areas for the conservation of plant biodiversity in this region. The study includes an analysis of species richness at the level of political units (municipalities), vegetation types, and grid cells of 10 × 10 km. Additionally, the corrected weighted endemism index was calculated using the grid cells. The sites with the richest taxa are located in the mountain areas; however, these do not coincide with the sites with the highest index of endemism since a high percentage of taxa have a restricted distribution to one of the proposed units. Thirty-six taxa are recognized with restricted distribution to the boundaries of Comarca Lagunera, most of them considered as microendemics, which have been described in recent years. Therefore, it is necessary to establish biodiversity conservation programs in the region since much of Comarca Lagunera territory is dedicated to agricultural and industrial activities.

Biological Diversity of Mexico

ISBN:
Category : Science

Pages : 864
Book Description
Mexico is among the richest countries in the world in terms of the number of native animal and plant species. Found in a wide variety of habitats--from alpine meadows and tropical forests to vast stretches of desert and isolated pockets of biogeographical uniqueness--these species comprise a fascinating, important, and vastly underutilized biological laboratory. This volume presents a collection of selected papers that explore this marvelous biological abundance. The book is divided into six parts. The first section sets the stage with geological and paleobotanical overviews; the succeeding five sections employ a strong taxonomic base to document species richness, endemism and distribution for animals and plants, followed by reviews of contrasting ecosystems and plants that are closely associated with humans. The last section summarizes the disheartening rate of habitat destruction which threatens to diminish this diversity. In addition to the purely scientific value of this important work, it provides the much-needed basic data that will help conservation policymakers assess and respond to Mexico's ecological evolution.

Author: Where Have All the Birds Gone?

Languages : en
Pages : 224
Book Description
"Things are going wrong with our environment," writes John Terborgh, "even the parts of it that are nominally protected. If we wait until all the answers are in, we may find ourselves in a much worse predicament than if we had taken notice of the problem earlier. By waiting, one risks being too late; on the other hand, there can be no such thing as being too early." Terborgh's warnings are essential reading for all who care about migratory birds and our natural environment. Why are tropical migrant species disappearing from our forests? Can we save the birds that are left? Terborgh takes a more comprehensive view of migratory birds than is usual--by asking how they spend their lives during the half-year they reside in the tropics. By scrutinizing ill-planned urban and suburban development in the United States and the tropical deforestation of Central and South America, he summarizes our knowledge of the subtle combination of circumstances that is devastating our bird populations. This work is pervaded by Terborgh's love for the thrushes, warblers, vireos, cuckoos, flycatchers, and tanagers that inhabited his family's woodland acreage while he was growing upbirds that no longer live there, in spite of the preservation of those same woods as part of a county park. The book is a tour of topics as varied as ecological monitoring, the plight of the Chesapeake wetlands, the survival struggle of Central American subsistence farmers, and the management of commercial forests.

Gentry's R’o Mayo Plants
Author: Paul Schultz MartinPublisher: University of Arizona Press
ISBN: 9780816517268
Category : Nature
Languages : en
Pages : 584
Book Description
The Río Mayo region of northwestern Mexico is a major geographic area whose natural history remains poorly known to outsiders. Lying in a region where desert and tropical, northern and southern, and continental and coastal species converge, it boasts an abundance of flora first documented by Howard Scott Gentry in 1942 in a book now widely regarded as a classic of botanical literature. This new book updates and amends Gentry's Río Mayo Plants. Undertaken with Gentry's support and participation before his death in 1993, it reproduces the original text, which appears here with annotations, and contains information on over 2,800 taxa—more than twice the 1,200 species first described by Gentry. The annotated list of plants includes information on distribution, habitat, appearance, common names, and indigenous uses. A new introduction provides historical background and a review of geography and vegetation. It also describes changes to the land and river wrought by agricultural development, expanded grazing, and lumbering. Throughout the text, the authors have endeavored to provide information on Río Mayo vegetation while emphasizing local knowledge and use of plants, to preserve Gentry's field-oriented focus, and to present botanical information with Gentry's exuberance and style. Río Mayo Plants has long stood as a book that displays a scientist's love of the English language, his fondness for native peoples, and his eye for beauty in nature. This updating of that work fills a gap in the botanical literature of this portion of North America and will be useful not only for botanists but also for biogeographers, taxonomists, land managers, and conservationists.
