This book is number two in a series for Primates in Fragments. In this volume, ten years after the first http://www.springer.com/social+sciences/anthropology+%26+archaeology/book/978-0-306-47696-9, we continue to address issues regarding primates within a fractured landscape. There are seven sections based on specific categories of primates in fragments. In the Introductory section, authors discuss the issues surrounding primates in remnant habitats as well as encourage discussion about what we mean by fragmentation on a landscape scale. In the Long-Term and Regional Studies section, authors present information on changes that have occurred during longer studies as well as changes that have occurred over regions. In the Landscape, Metapopulations and the Matrix section, authors cover topics from dry to moist forests, and from metapopulations to single species use of multiple fragments locations. In Feeding and Behavioral Ecology, authors take a closer look at the flexibility and responsiveness of primates in fragments in terms of their food choices, resource use, and behavioral changes. In Endemic, Endangered, and Nocturnal Primates authors uncover details involving critical primates living in major city centers to the heights of the Himalayas. In Genetics, Disease and Parasites authors cover topics including population viability, disease and parasite transmission between primates in fragments and humans. Finally, in the Conservation and Ecology: Threats and Management section, we synthesize information in this volume and make recommendations for the future of work in this field and the survivability of primates in fragments.

Igapó forests are a common part of the Amazon whose ecosystems are critical to our shared human future. The introduction addresses the structure, function and dynamics of igapó forests in the Amazon basin, focusing on their uniqueness due to their high level of complexity defined as the many ways that different components of igapó forests in the Amazon basin ecosystem interact and also on how those interactions are on a higher-order compared to other tropical forests. The text then breaks down the igapó ecosystem using these sections: (1) Igapó forests over space and time, (2) Water, light and soils, (3) The carbon cycle, (4) Litter, fungi and invertebrates, (5) Vertebrates, (6) Plant population studies, (7) Plant community studies, and (8) Human impacts and management. Experts from around the world serve as chapter authors that review what is known about their specific part of the igapó ecosystem, what research they have done, and also what needs to be done in the future.

Face to the current global energy crisis, there is an urgent necessity of searching for alternatives to fossil fuels, and this book shows how timber is a promising resource for sustainable energy production. Northeast Mexico represents an important forest resource to satisfy the needs of the population in these areas. In order to harness these forest resources, technology for exploring these valuable resources must be developed. These technologies (with special reference to biology and wood technologies) are available in scattered form in a few books but there is no central, comprehensive source for practical forest scientists for adopting efficient forest management, practice, and exploration. This book deals with the characterization of the vegetation, morphology, phenological development, biomass production (leaf, litter, wood), and bioenergy of some timber-yielding species of Northeast Mexico, which will serve as a guide to study timber-yielding plants in the native vegetation of Tamaulipan thornscrub and experimental plantations. This includes morphology, vegetation cover, biomass production in terms of volume leaf biomass, litter, and volume of fire wood and timber. Special emphasis is given to the estimation of bioenergy products and chemical composition (Ph, extractable lignin, and inorganic elements). Large variations exist in vegetation cover, morphology, phenological development, biomass production of leaf and litter, volume of wood and various variable of bioenergy products among the selected species. The maximum production was found in summer and the volume of the harvestable timber was obtained in experimental plantations. This book, therefore, will serve as a practical handbook to characterize timber-yielding plants, which will help to efficiently manage forestry resources.

In order to feed the world, global agriculture will have to double food production by 2050. As a result, the use of soils with fertilizers and pesticides in agronomic ecosystems will increase, taking into account the sustainability of these systems and also the provision of food security. Thus, soil ecosystems, their health, and their quality are directly involved in sustainable agronomical practices, and it is important to recognize the important role of soil microbial communities such as mycorrhizal fungi, their biodiversity, interactions, and functioning. Soil ecosystems are under the threat of biodiversity loss due to an increase of cultivated areas and agronomic exploitation intensity. Also, changes in land use alter the structure and function of ecosystems where biodiversity is vital in the ecosystem. Soils are a major aid in food production in all terrestrial ecosystems; however, this means they are also involved in gas emission and global warming. Thus, in agronomic ecosystems, several mitigation practices have been proposed to promote the increase of carbon soil stock, and the reduction of warming gas emission from soils. In South America, most of the rural population depends economically on agriculture and usually works in family units. New, organic, safe, and sustainable agro-forestry practices must be applied to support local communities and countries to achieve hunger eradication, rural poverty reduction, and sustainable development. This book compiles new information for mycorrhizal occurrence in natural and anthropic environments in South America. It includes new reports of mycorrhizal fungi diversity along different mycorrhizal types and their effect on plant communities, plant invasions, the use of mycorrhizal fungi for ecological and sustainable studies, management programs of natural and agroecosystems, and forestry and food-secure production. This book fills the gaps in biodiversity knowledge, management and safe food production of mycorrhizas. It should be a valuable help to researchers, professors and students, to aid in use of mycorrhizal fungi while also focusing on their biodiversity, sustainable safe food production, and conservation perspectives.

The three islands comprising the Cayman Islands support 415 native taxa in a land area over 100 square miles, 29 of which are uniquely Caymanian. This field guide satisfies the needs of the professional botanist, while providing the non-expert and eco-tourist with an introduction to the unique endemic flora of the Cayman Islands.

In recent years considerable progress has been made in elucidating wood decay mechanisms. This basic knowledge not only has the potential to develop alternative environmentally-benign wood preservatives, but may also impact other areas such as bioremediation and pulp and paper. This book will summarize the latest knowledge of the developments, potential impacts, and applications from some of the world's leading experts.
