When first published in 1971, Amazonia was a pioneering contribution to the emerging field of cultural ecology. Betty Meggers argued that the Amazon's luxurious vegetation concealed significant limitations for human exploitation, placing a ceiling on pre-Columbian population density and social complexity. Amazonia in this revised new edition includes recent biological and climatic data. Ethnographic and archaeological evidence reemphasize the complexity of the ecosystem and broaden our understanding of past and present sophisticated adaptations among indigenous groups.

Chinese New Migrants In Suriname written by Paul B. Tjon Sie Fat and has been published by Amsterdam University Press this book supported file pdf, txt, epub, kindle and other format this book has been release on 2009 with Social Science categories.

This book covers various aspects of New Chinese Migration in Suriname in the 1990s and early 2000s. It is an ethnography of New Chinese Migrants in the context of South- South migration, but also a first ethnography of Chinese in Suriname, as well as an analysis of Surinamese ethnic discourse and ethnopolitics. Starting in the 1990s, renewed immigration from China changed the dynamics of the Surinamese Chinese community, which developed from a Hakka enclave to a culturally and linguistically diverse, modern Chinese migrant group. Local positioning strategies of Chinese had always depended on ethnic entrepreneurship and political participation, but were now complicated by anti-immigrant sentiments.

The scope of ecology. The clue to the field of ecology is found in the Greek word, οἲκος, home. The point of view in the following treatise is constantly that which is inherent in the term itself. Ecology is therefore considered the dominant theme in the study of plants, indeed, as the central and vital part of botany. This statement may at first appear startling, if not unfounded, but mature reflection will show that all the questions of botanical science lead sooner or later to the two ultimate facts: plant and habitat. The essential truth of this has been much obscured by detached methods of study in physiology, morphology, and histology, which are too often treated as independent fields. These have suffered incomplete and unsymmetric development in consequence of extreme specialistic tendencies. Analytic methods have dominated research to the exclusion of synthetic ones, which, in a greatly diversified field, must be final, if botanical knowledge is something to be systematized and not merely catalogued. Physiology in particular has suffered at the hands of detached specialists. Originally conceived as an inquiry into the origin and nature of plants, it has been developed strictly as a study of plant activities. It all but ignores the physical factors that control function, and the organs and tissues that reflect it. Ecology and physiology. There can be little question in regard to the essential identity of physiology and ecology. This is evident when it is clearly seen that the present difference between the two fields is superficial. Ecology has been largely the descriptive study of vegetation; physiology has concerned itself with function; but, when carefully analyzed, both are seen to rest upon the same foundation. In each, the development is incomplete: ecology has so far been merely superficial, physiology too highly specialized. The one is chaotic and unsystematized, the other too often a minute study of function under abnormal circumstances. The greatest need of the former is the introduction of method and system, of the latter, a broadening of scope and new objectives. The growing recognition of the identity of the two makes it desirable to anticipate their final merging, and to formulate a system that will combine the good in each, and at the same time eliminate superficial and extreme tendencies. In this connection, it becomes necessary to point out to ecologist and physiologist alike that, while they have been working on the confines of the same great field, each must familiarize himself with the work and methods of the other, before his preparation is complete. Both must broaden their horizons, and rearrange their views. The ecologist is sadly in need of the more intimate and exact methods of the physiologist: the latter must take his experiments into the field, and must recognize more fully that function is but the middleman between habitat and plant. It seems probable that the final name for the whole field will be physiology, although the term ecology has distinct advantages of brevity and of meaning. In this event, however, it should be clearly recognized that, although the name remains the same, the field has become greatly broadened by new viewpoints and new methods.

The Amazon -that name was given to the biggest river on earth and is often used for the whole area of its basin too. This geographical region is currently referred to as Amazonia, thus emphasizing the peculiar character of its aquatic and terrestrial reaches. The Amazon embodied the dream of many a naturalist to explore what for a long time was a terra incognita. In recent years, however, Amazonia has emerged as a main centre for 'development' by some of the countries in which it lies and by foreign industrialized nations. The development projects and enterprises have aroused woridwide interest and have given rise to discussions on their aims and their consequences to the Amazonian nature. Limnological and ecological investigations in Amazonia started only about 40 years ago. The editor had the good fortune to partake in them from the very beginning. He spent his decisive years in Amazonia, and dedicated his life's work to that research and to that country and the Amazonian people. Nearing the end of his scicntific activities, hc is gratcful to bc ablc to summarizc in this book most of the knowledge we possess at present of Amazonian limnology and landscape ecology.
