Origin And Evolution Of Tropical Rain Forests

Although tropical rain forests form the world?s most species-rich ecosystems, their origin and history remain unclear, except on the very short timescale of the last 40 000 years or so. This book provides the first comprehensive review of the history of tropical rain forests on a long term geological timescale, commencing with the origin of the angiosperms over 100 million years ago, which today overwhelmingly dominate these forests. Tropical rain forest evolution is discussed in a global context within an up to date plate tectonic, palaeogeographical and palaeoclimatic framework, primarily by reference to the record of fossil pollen and spores. A particularly important aspect of this book is that in addition to published literature, it relies heavily on unpublished palynological data generated for petroleum companies during the course of hydrocarbon exploration programmes. Without access to such data the book could not have been written. The main text of the book reviews the evolution of tropical rain forests on a continent by continent basis, culminating with a global synthesis of their history in relation to the changing positions of the world?s tectonic plates and changing climates. This section also establishes the age of the great tropical rain forest blocks and identifies the world?s oldest tropical rain forests. The final chapter compares 20th Century tropical rain forest destruction with prehistoric forest clearance in temperate regions, and looks for analogues of the present phase of destruction within the geological record before considering long term implications of total rain forest destruction. The book will be of interest to all concerned with tropical rain forests, especially biologists, botanists, ecologists, and students of evolution. It will be valuable for postgraduates and advanced undergraduates, as well as stratigraphers, palaeobotanists, palynologists, and petroleum geologists.

Synthesizing theoretical & empirical analyses of the processes that help shape these unique ecosystems, 'Tropical Rainforests' looks at the effects of evolutionary histories, past climate change, & ecological dynamics on the origin & maintenance of tropical rainforest communities.

In popular discourse, tropical forests are synonymous with 'nature' and 'wilderness'; battlegrounds between apparently pristine floral, faunal, and human communities, and the unrelenting industrial and urban powers of the modern world. It is rarely publicly understood that the extent of human adaptation to, and alteration of, tropical forest environments extends across archaeological, historical, and anthropological timescales. This book is the first attempt to bring together evidence for the nature of human interactions with tropical forests on a global scale, from the emergence of hominins in the tropical forests of Africa to modern conservation issues. Following a review of the natural history and variability of tropical forest ecosystems, this book takes a tour of human, and human ancestor, occupation and use of tropical forest environments through time. Far from being pristine, primordial ecosystems, this book illustrates how our species has inhabited and modified tropical forests from the earliest stages of its evolution. While agricultural strategies and vast urban networks emerged in tropical forests long prior to the arrival of European colonial powers and later industrialization, this should not be taken as justification for the massive deforestation and biodiversity threats imposed on tropical forest ecosystems in the 21st century. Rather, such a long-term perspective highlights the ongoing challenges of sustainability faced by forager, agricultural, and urban societies in these environments, setting the stage for more integrated approaches to conservation and policy-making, and the protection of millennia of ecological and cultural heritage bound up in these habitats.

This is a comprehensive, attractive, and readable introduction to tropical rain forest ecology, biogeography, and management. It tackles the subject at local, regional, and global scales, and is both up-to-date and fully integrated across disciplines.

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.

In recent years, tropical forests have received more attention and have been the subject of greater environmental concern than any other kind of vegetation. There is an increasing public awareness of the importance of these forests, not only as a diminishing source of countless products used by mankind, nor for their effects on soil stabilization and climate, but as unrivalled sources of what today we call biodiversity. Threats to the continued existence of the forests represent threats to tens of thousands of species of organisms, both plants and animals. It is all the more surprising, therefore, that there have been no major scientific accounts published in recent years since the classic handbook by Paul W. Richards, The Tropical Rain Forest in 1952. Some excellent popular accounts of tropical rain forests have been published including Paul Richard's The Life of the Jungle, and Catherine Caulfield's In the Rainforest and Jungles, edited by Edward Ayensu. There have been numerous, often conflicting, assessments of the rate of conversion of tropical forests to other uses and explanations of the underlying causes, and in 1978 UNESCO/UNEPI FAO published a massive report, The Tropical Rain Forest, which, although full of useful information, is highly selective and does not fully survey the enormous diversity of the forests.

The first edition of Tropical Rain Forests: an Ecological and Biogeographical Comparison exploded the myth of ‘the rain forest’ as a single, uniform entity. In reality, the major tropical rain forest regions, in tropical America, Africa, Southeast Asia, Madagascar, and New Guinea, have as many differences as similarities, as a result of their isolation from each other during the evolution of their floras and faunas. This new edition reinforces this message with new examples from recent and on-going research. After an introduction to the environments and geological histories of the major rain forest regions, subsequent chapters focus on plants, primates, carnivores and plant-eaters, birds, fruit bats and gliding animals, and insects, with an emphasis on the ecological and biogeographical differences between regions. This is followed by a new chapter on the unique tropical rain forests of oceanic islands. The final chapter, which has been completely rewritten, deals with the impacts of people on tropical rain forests and discusses possible conservation strategies that take into account the differences highlighted in the previous chapters. This exciting and very readable book, illustrated throughout with color photographs, will be invaluable reading for undergraduate students in a wide range of courses as well as an authoritative reference for graduate and professional ecologists, conservationists, and interested amateurs.

Rain forests represent the world's richest repository of terrestrial biodiversity, and play a major role in regulating the global climate. They support the livelihoods of a substantial proportion of the world's population and are the source of many internationally traded commodities. They remain (despite decades of conservation attention) increasingly vulnerable to degradation and clearance, with profound though often uncertain future costs to global society. Understanding the ecology of these diverse biomes, and peoples' dependencies on them, is fundamental to their future management and conservation. Tropical Rain Forest Ecology, Diversity, and Conservation introduces and explores what rain forests are, how they arose, what they contain, how they function, and how humans use and impact them. The book starts by introducing the variety of rain forest plants, fungi, microorganisms, and animals, emphasising the spectacular diversity that is the motivation for their conservation. The central chapters describe the origins of rain forest communities, the variety of rain forest formations, and their ecology and dynamics. The challenge of explaining the species richness of rain forest communities lies at the heart of ecological theory, and forms a common theme throughout. The book's final section considers historical and current interactions of humans and rain forests. It explores biodiversity conservation as well as livelihood security for the many communities that are dependent on rain forests - inextricable issues that represent urgent priorities for scientists, conservationists, and policy makers.

An engaging portrait of a community of biologists, The Tapir's Morning Bathis a behind-the-scenes account of life at a tropical research station that"conveys the uncertainties, frustrations, and joys of [scientific] fieldwork" (Science). On Panama's Barro Colorado Island, Elizabeth Royte worksalongside the scientists -- counting seeds, sorting insects, collectingmonkey dung, radiotracking fruit bats -- as they struggle to parse theintricate workings of the tropical rain forest. While showing the humanside of the scientists at work, Royte explores the tensions between the slow pace of basic research and the reality of a world that may not have time to wait for answers.

This is the first book to examine how tropical rain forest ecology is altered by climate change, rather than simply seeing how plant communities were altered. The book’s goal is to provide a current overview of the impacts of climate change on tropical forests. It aims to investigate past, present, and future climatic influences on the ecosystems with the highest biodiversity on the planet.
