The Equatorial Rain Forest: A Geological History presents the equatorial vegetation as a dynamic entity with varied and highly significant history. It also discusses other types of equatorial regions. It addresses the vegetational history from a palaeoecological viewpoint. Some of the topics covered in the book are the vegetation of equatorial regions; the prelude to the quaternary; the quaternary vegetation of equatorial Latin America; the quaternary vegetation of equatorial Africa; the cretaceous period; and the quaternary vegetation of equatorial indo-malesia. The value of vegetational history is fully covered. The effect of man on vegetation is discussed in detail. The text describes in depth the methods of studying vegetational history. The Paleocene, Eocene, and Oligocene epochs are presented completely. A chapter is devoted to the palynological evidence and synthesis. Another section focuses on the xeroseres, hydroseres and related successions. The book can provide useful information to botanists, geologists, students, and researchers.

This is the first book to review all the fields of equatorial electrojet phenomena and their relevant theories in one volume. In certain relevant sections, the book discusses both the equatorial electrojet and the world-wide parts of the Sq current systems. Onwumwchili is an internationally known and highly respected expert in the equatorial electrojet field- a brand of geomagnetism.

Perhaps the contributions of South American archaeology to the larger field of world archaeology have been inadequately recognized. If so, this is probably because there have been relatively few archaeologists working in South America outside of Peru and recent advances in knowledge in other parts of the continent are only beginning to enter larger archaeological discourse. Many ideas of and about South American archaeology held by scholars from outside the area are going to change irrevocably with the appearance of the present volume. Not only does the Handbook of South American Archaeology (HSAA) provide immense and broad information about ancient South America, the volume also showcases the contributions made by South Americans to social theory. Moreover, one of the merits of this volume is that about half the authors (30) are South Americans, and the bibliographies in their chapters will be especially useful guides to Spanish and Portuguese literature as well as to the latest research. It is inevitable that the HSAA will be compared with the multi-volume Handbook of South American Indians (HSAI), with its detailed descriptions of indigenous peoples of South America, that was organized and edited by Julian Steward. Although there are heroic archaeological essays in the HSAI, by the likes of Junius Bird, Gordon Willey, John Rowe, and John Murra, Steward states frankly in his introduction to Volume Two that “arch- ology is included by way of background” to the ethnographic chapters.

Chapters offer new understandings of how ranked societies emerged and developed in prehistoric southern Central America and northern South America (the "Isthmo-Colombian Area"). The emphasis is on integrating the results of studies of social units at a range of different scales from the household to the local commuity to the region and beyond.
