This book addresses an important problem in ecology: how are communities assembled from species pools? This pressing question underlies a broad array of practical problems in ecology and environmental science, including restoration of damaged landscapes, management of protected areas, and protection of threatened species. This book presents a simple logical structure for ecological assembly and addresses key areas including species pools, traits, environmental filters, and functional groups. It demonstrates the use of two predictive models (CATS and Traitspace) and consists of many wide-ranging examples including plants in deserts, wetlands, and forests, and communities of fish, amphibians, birds, mammals, and fungi. Global in scope, this volume ranges from the arid lands of North Africa, to forests in the Himalayas, to Amazonian floodplains. There is a strong focus on applications, particularly the twin challenges of conserving biodiversity and understanding community responses to climate change.
Southeast Asia is highly diversified in terms of socio-ecosystems and biodiversity, but is undergoing dramatic environmental and social changes. These changes characterize the recent period and can be illustrated by the effects of the Green Revolution in the late 1960s and 1970s, to the globalization of trade and increasing agronomic intensification over the past decade. Biodiversity Conservation in Southeast Asia provides theoretical overviews and challenges for applied research in living resource management, conservation ecology, health ecology and conservation planning in Southeast Asia. Five key themes are addressed: origin and evolution of Southeast Asian biodiversity; challenges in conservation biology; ecosystem services and biodiversity; managing biodiversity and living resources; policy, economics and governance of biodiversity. Detailed case studies are included from Thailand and the Lower Mekong Basin, while other chapters address cross-cutting themes applicable to the whole Southeast Asia region. This is a valuable resource for academics and students in the areas of ecology, conservation, environmental policy and management, Southeast Asian studies and sustainable development.
"Irresistible" - Literary Review Fig trees have affected humanity in profound but little-known ways: they are wish-fulfillers, rainforest royalty, more precious than gold. Ladders to Heaven tells their incredible story. They fed our pre-human ancestors, influenced diverse cultures and played a key role in the birth of civilisation. More recently, they helped restore life after Krakatoa's catastrophic eruption and proved instrumental in Kenya's struggle for independence. Figs now sustain more species of bird and mammal than any other fruit - in a time of falling trees and rising temperatures, they offer hope. Theirs is a story about humanity's relationship with nature, as relevant to our past as it is to our future.

This study of plant anatomy is based on newly available data on the structure and spatial organization of the vascular system of plants. For the first time, by means of a new technique of intracellular moulding, the vascular system can be observed in its length. Many examples are chosen from among the major groups of the plant kingdom to illustrate the vast field of applications of histological moulding: anatomical structures that have so far been little understood or unknown are described and hypotheses relative to the cambial functioning are presented. Following a summary of basic concepts of xylem anatomy, the text is illustrated with many diagrams and photographs of moulds made for the most part with scanning electron microscope. The successive steps of the technical implementation of moulding, are described with precision. The book is addressed not only to scientists and students, but also to professionals concerned with wood, trees, and plants in general.
The book provides data on all the species of the two genera Genera Brachystelma Sims and Ceropegia L. in India for their bioprospection and conservation.

A biography of a staple grain we often take for granted, exploring how wheat went from wild grass to a world-shaping crop. At breakfast tables and bakeries, we take for granted a grain that has made human civilization possible, a cereal whose humble origins belie its world-shaping power: wheat. Amber Waves tells the story of a group of grass species that first grew in scattered stands in the foothills of the Middle East until our ancestors discovered their value as a source of food. Over thousands of years, we moved their seeds to all but the polar regions of Earth, slowly cultivating what we now know as wheat, and in the process creating a world of cuisines that uses wheat seeds as a staple food. Wheat spread across the globe, but as ecologist Catherine Zabinski shows us, a biography of wheat is not only the story of how plants ensure their own success: from the earliest bread to the most mouthwatering pasta, it is also a story of human ingenuity in producing enough food for ourselves and our communities. Since the first harvest of the ancient grain, we have perfected our farming systems to grow massive quantities of food, producing one of our species' global mega crops-but at a great cost to ecological systems. And despite our vast capacity to grow food, we face problems with undernourishment both close to home and around the world. Weaving together history, evolution, and ecology, Zabinski's tale explores much more than the wild roots and rise of a now-ubiquitous grain: it illuminates our complex relationship with our crops, both how we have transformed the plant species we use as food, and how our society-our culture-has changed in response to the need to secure food sources. From the origins of agriculture to gluten sensitivities, from our first selection of the largest seeds from wheat's wild progenitors to the sequencing of the wheat genome and genetic engineering, Amber Waves sheds new light on how we grow the food that sustains so much human life.

Grasses are a principal source of food for mankind and play an important role in stabilizing the land surface of much of the globe. Understanding seed dormancy in the Gramineae is therefore of considerable significance to world agriculture and global ecology. This book provides a comprehensive review of the occurrence and explanation of seed dormancy in grasses. Experimental evidence is considered in depth for a single species, the wild oat (Avena fatua), probably the most widely studied species for understanding seed dormancy in the plant kingdom. The evidence for this species is compared with other examples among the Gramineae to reach some general conclusions about the nature of seed dormancy in grasses. Essential reading for all those who need to understand the mechanisms of seed dormancy, this book will be a valuable text for advanced students and professionals in plant physiology, crop science, plant breeding and agronomy.
For centuries, people have understood that forests, and our utilisation of them, influence the climate. With modern environmental concerns, there is now scientific, governmental, and popular interest in planting trees for climate protection. This book examines the historical origins of the idea that forests influence climate, the bitter controversy that ended the science, and its modern rebirth. Spanning the 1500s to the present, it provides a broad perspective across the physical and biological sciences, as well as the humanities, to explain the many ways forests influence climate. It describes their use in climate-smart forestry and as a natural climate solution, and demonstrates that in the forest-climate question, human and sylvan fates are linked. Accessibly written with minimal mathematics, it is ideal for students in environmental and related sciences, as well as anyone with an interest in understanding the environmental workings of forests and their interactions with climate.

This volume provides a wide-ranging survey of all the major grain legumes from the standpoint of both their evolution and their potential for further development and improvement as economically important food crops. The legumes have a vital role to play in both the developed and developing worlds by providing an alternative nitrogen source to the artificially produced nitrogenous fertilizers used, which although boosting cereal yields, often have had adverse environmental effects. The grain legumes are a valuable crop possessing the ability to fix nitrogen by Rhizobium biosynthesis and thus contribute to the natural nitrogen cycle. The book surveys the changes which have occurred in the course of plant domestication leading to our present pulse crops and oilseed legume crops. The author then discusses the benefits to be gained from evaluation and improvement of grain legume genetic resources. It is through this comparative approach that the overall potential of these crops is highlighted.
This book is a bridge between organismal/community approaches to food web dynamics and ecosystem-level approaches to production. It explains topics including autotrophy, heterotrophy, omnivory, decomposition, foraging behavior and theory, trophic cascades, bioenergetics, and production. |
