DOWNLOAD EBOOKThe massive grasslands of Brazil -- known as the cerrados -- which cover roughly a quarter of its land surface and are among the most threatened regions in South America, have received little media attention. This book brings together leading researchers on the area to produce the first detailed account in English of the natural history and ecology of the cerrado/savanna ecosystem. Given their extent and threatened status, the richness of their flora and fauna, and the lack of familiarity with their unique ecology at the international level, the cerrados are badly in need of this important and timely work.

DOWNLOAD EBOOKAnts have always fascinated the nature observer. Reports from ancient Egypt and Mesopotamia indicate that ants interested humans long ago. Myrmecology as a science had its beginning in the last century with great naturalists like Andre, Darwin, Emery, Escherich, Fabre, Fields, Forel, Janet, Karawaiew, McCook, Mayr, Smith, Wasmann and Wheeler. They studied ants as an interesting biological phenomenon, with little thought of the possible beneficial or detrimental effects ants could have on human activities (see Wheeler 1910 as an example). When Europeans began colonizing the New World, serious ant problems occurred. The first reports of pest ants came from Spanish and Portuguese officials of the fifteenth and sixteenth centuries in Trinidad, The West Indies, Central America and South America. Leaf-cutting ants were blamed for making agricultural development almost impossible in many areas. These ants, Atta and Acromyrmex species, are undoubtedly the first ants identified as pests and may be considered to have initiated interest and research in applied myrmecology (Mariconi 1970).

DOWNLOAD EBOOKThis is the first volume of the monumental Handbook of Middle American Indians, a definitive encyclopaedia of the environment, archaeology, ethnology, social anthropology, ethnohistory, linguistics, and physical anthropology of the native peoples of Mexico and Central America. The Handbook was published in cooperation with the Middle American Research Institute of Tulane University under the general editorship of Robert Wauchope (1909–1979). This volume of the Handbook was edited by Dr. Robert C. West (1913–2001), Boyd Professor of Geography at Louisiana State University, an outstanding authority on Latin America. He was formerly cultural geographer for the Smithsonian Institution. Included in this first volume are chapters written by leading authorities in various fields of the natural and social sciences that are concerned with the natural environment of Middle America, its role in the shaping of Indian cultures, the earliest primitive hunters of this area, the beginnings of agriculture, and the broad patterns of prehistoric civilizations there. There are articles on the geohistory and paleogeography of Middle America, its surface configuration and associated geology, hydrography, the American Mediterranean, oceanography and marine life along the Pacific coast, weather and climate, natural vegetation, the soils and their relation to the Indian peoples and cultures, fauna , the natural regions of Middle America, the primitive hunters, the food-gathering and incipient agricultural stage of prehistoric Middle America, origins of agriculture there, and the patterns of farming life and civilization. The Handbook of Middle American Indians was assembled and edited at the Middle American Research Institute of Tulane University with the assistance of grants from the National Science Foundation and under the sponsorship of the National Research Council Committee on Latin American Anthropology.
