West Africa and the eastern Atlantic stretching from Mauritania in the north to Namibia in the south offer a large latitudinal stretch incorporating nearly symmetrical climatic gradients from the Equator. On the time scale of Quaternary Glacial and Interglacial cycles, today, we possess well-documented and recently published marine sedimentary records showing changes in oceanic and atmospheric circulations and terrestrial fluxes. Deep-sea sediment records contain a wide range of palaeoenvironmental indicators like oxygen and carbon isotopes, alkenones, foraminiferal and other planktonic assemblages over time periods up to and greater than 125,000 years. These are signals of temperature and circulation shifts and allow Interglacial and Glacial comparisons on a regional and inter-hemispheric scale. However, this effort to synthesize the existing knowledge cannot yet aspire to a global modelling. Linking with terrestrial records, albeit spatially patchy and generally lacking a firm chronology, this book points to shorter time scale chronologies from lakes, marshes and river deposits. Diverse and not very wellknown literature, both French and English, is reported here. Lastly, the book records recent knowledge of the first steps of human occupation of frequently hostile environments and considers the environmental impact of ancient and modern societies. * Covers the recent studies about marine Quaternary environments off West Africa, as well as continental Quaternary environments of tropical and sub-tropical West Africa (over 10,000 to 100,000 years) * Compares the parallel between palae-oenvironmental trends according to latitudinal gradients

First published in 1986, this book describes the most important medicinal plants in tropical West Africa and similar humid tropical climates. After a short introduction about early traditional medicine, the bulk of the book gives an account of locally occurring plants, grouped by their medicinal actions. Plants that affect the cardiovascular and nervous systems are discussed, as are those with antibiotic, insecticidal and molluscicidal properties. Those which affect the hormonal systems of humans are catalogued and so are others that act as adrenal-cortex, sex and thyroid hormones. There is a full botanical index, which includes the commonly found synonyms for many of the plants and the work is illustrated by the author's own water colours. It may be of particular interest and use to pharmacists, biochemists, botanists and pharmacologists and of great value to those who exploit locally available resources in treating diseases in tropical areas.

Meteorology of tropical West Africa: the Forecasters’ Handbook presents the science and practice of weather forecasting for an important region of the tropics. Connecting basic theory with forecasting practice, the book provides a unique training volume for operational weather forecasters, and is also suitable for students of tropical meteorology. The West African region contains a number of archetypal climatic zones, meaning that the science of its weather and climate applies to many other tropical regions. West Africa also exhibits some of the world’s most remarkable weather systems, making it an inspiring region for students to investigate. The weather of West Africa affects human livelihoods on a daily basis, and can contribute to hardship, poverty and mortality. Therefore, the ability to understand and predict the weather has the potential to deliver significant benefits to both society and economies. The book includes comprehensive background material alongside documentation of weather forecasting methods. Many examples taken from observations of West African weather systems are included and online case-studies are referenced widely.

While products such as bananas, pineapples, kiwifruit and citrus have long been available to consumers in temperate zones, new fruits such as lychee, longan, carambola, and mangosteen are now also entering the market. Confirmation of the health benefits of tropical and subtropical fruit may also promote consumption further. Tropical and subtropical fruits are particularly vulnerable to postharvest losses, and are also transported long distances for sale. Therefore maximising their quality postharvest is essential and there have been many recent advances in this area. Many tropical fruits are processed further into purees, juices and other value-added products, so quality optimization of processed products is also important. The books cover current state-of-the-art and emerging post-harvest and processing technologies. Volume 1 contains chapters on particular production stages and issues, whereas Volumes 2, 3 and 4 contain chapters focused on particular fruit. Chapters in Volume 2 review the factors affecting the quality of different tropical and subtropical fruits from açai to citrus fruits. Important issues relevant to each product are discussed, including means of maintaining quality and minimizing losses postharvest, recommended storage and transport conditions and processing methods, among other topics. With its distinguished editor and international team of contributors, Volume 2 of Postharvest biology and technology of tropical and subtropical fruits, along with the other volumes in the collection, will be an essential reference both for professionals involved in the postharvest handling and processing of tropical and subtropical fruits and for academics and researchers working in the area.

Wynne''s "Checklist revision" is a compilation of the taxa of benthic marine algae occurring in the broad area of the tropical and subtropical Western Atlantic Ocean. It thus covers the region from North Carolina to southern Brazil, which is the same domain as the 1960 flora of W. R. Taylor. It includes a total of 1,227 species of benthic marine algae: 763 species of red algae, 168 species of brown algae, and 296 species of green algae. There are also Notes in regard to specific information for some of the taxa treated, where appropriate. This publication includes an extensive bibliography of pertinent literature for the period following the publication of the first checklist in 1986. The Checklist includes a Table of geographic regions (countries in the region covered and coastal States of the southeastern USA) listing the literature. Five figures of the coastal regions treated are also provided.
