Though seasonally dry tropical forests are equally as important to global biodiversity as tropical rainforests, and are one of the most representative and highly endangered ecosystems in Latin America, knowledge about them remains limited because of the relative paucity of attention paid to them by scientists and researchers and a lack of published information on the subject. Seasonally Dry Tropical Forests seeks to address this shortcoming by bringing together a range of experts in diverse fields including biology, ecology, biogeography, and biogeochemistry, to review, synthesize, and explain the current state of our collective knowledge on the ecology and conservation of seasonally dry tropical forests. The book offers a synthetic and cross-disciplinary review of recent work with an expansive scope, including sections on distribution, diversity, ecosystem function, and human impacts. Throughout, contributors emphasize conservation issues, particularly emerging threats and promising solutions, with key chapters on climate change, fragmentation, restoration, ecosystem services, and sustainable use. Seasonally dry tropical forests are extremely rich in biodiversity, and are seriously threatened. They represent scientific terrain that is poorly explored, and there is an urgent need for increased understanding of the system's basic ecology. Seasonally Dry Tropical Forests represents an important step in bringing together the most current scientific information about this vital ecosystem and disseminating it to the scientific and conservation communities.

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
have also provided a west-to-east dispersal opportunity for some lowland
seasonally dry tropical forest species, moving from the coast to the Marañon
valley or vice versa (Bridgewater et al., 2003; LinaresPalomino et al., 2003).

Tropical dry deciduous forests (TDFs) can be found in severe and extremely variable climates characterized by low annual rainfall, 5-6 dry months within the annual cycle, and nutrient-poor soil. Several terms have been used for this vegetation type such as seasonally dry tropical forest (SDTF), tropical dry deciduous forest, monsoon forest, caatinga, cuabal, etc. More than any other factor, the lack of precipitation during a prolonged portion of the year is what produces true dry forest, an ecosystem type characterized by plants and animals with specific adaptations to survive the long dry season. Deciduousness is the single most important adaptation among plants to the extended droughts. Most of the trees drop their leaves after the rains end, and essentially halt photosynthesis, as they would otherwise be unable to survive the water loss during the dry season. TDFs are subject to intensive anthropogenic disturbances and are among the most at-risk ecosystems in the world. In order to assess the conservation status of this forest type, information is required on its distribution pattern, climate, the structure and functional traits of its vegetation, phenology, strategies for coping with drought and nutrient poverty, and disturbances and their effects. In this book, we review important studies on TDFs around the globe, particularly those in the northern dry deciduous forests of India. We put forward the claim that those TDFs that experience drought and arise on nutrient-poor sites feature adaptations such as deciduousness, as well as a variety of nutrient conservation strategies. They also experience biotic disturbances, which can result in fragmentation and ecosystem conversion, and therefore exhibit changes in biomass, productivity, and soil microbial biomass, etc.
In this book, we review important studies on TDFs around the globe, particularly those in the northern dry deciduous forests of India.

This publication gives a broad ecological overview of current condition in the three main parts of the biosphere, the seas, the land and inland waters. It also provides an historical context, from the origin of life on the planet onward. This has been done to demonstrate the long history of life on earth and to emphasise the brevity of human existence. The first part of the book includes a discussion of the components of biodiversity and an account of the expansion of this diversity through geological time and the pattern of distribution on the planet. The second part covers features of human impacts on the environment and the uses currently made of biodiversity. The main lesson drawn is that while life itself has remarkable tenacity, the tenure on earth of individual species has always been a strictly limited one. The environment of any species has two main roles: to provide the essential materials for growth and reproduction of the species and to remove or transform its waste products. A failure of either of these two will have an adverse or catastrophic impact on the species concerned. Ecosystems and the biosphere continue to function because the relentless pressure of natural selection has meant that organisms have evolved that thrive on the waste products of other organisms. This is considered in the book to be the function of biological diversity. A large number of tables and maps are presented in this publication, including a table on biodiversity at country level. This book has a companion volume, 'Life Counts'.

In this book, the habitats of our apelike ancestors of the Miocene epoch -- some 7 to 20 million years ago -- are re-examined from the perspective of knowledge yielded by the buried fossil soils in which they have been found. Fossilized soils, or paleosols, are distinctive layers within a sedimentary or volcanic sequence, and they also can be clues to former ecosystems and other aspects of paleoenvironments. Here the author characterizes in detail some 20 kinds of paleosols from the Kenyan and Pakistani localities for the dryopithicane and ramapithicine apes made famous by L.S.B. Leakey and D.R. Pilbeam. The extensive evidence cited allows for the reassessment of vegetation and landscape features of ancient tropical sites that are the source of much of what is known about our remote Miocene ancestors. The text also provides a basis for understanding paleosols formed in all tropical climates and alluvial settings, and offers a model for future research on human evolution and major events in the geological history of soils. It is a valuable resource for paleontologists, anthropologists, and soil scientists.
