Fundamentos de ecología: un enfoque ecosistémico es un texto de síntesis concebido como un manual de apoyo dirigido a estudiantes de pregrado en ciencias biológicas que quieran profundizar el estudio de la ecología y sobre todo el de los aspectos funcionales y estructurales del ecosistema. La ecología, en particular la noción de ecosistema, adquieren cada vez más importancia no solo por su valor conceptual sino también porque al definirse como la unidad mínima autosostenible, sobrepasa los términos académicos y lo posiciona en el nivel de la gestión y la política ambiental. El texto es una propuesta que tiene como objeto familiarizar la noción del ecosistema por medio de principios, definiciones, ciclos de materia, flujo de energía y aspectos generales de la organización de los ecosistemas. Estos temas, en la medida de lo posible, se complementan con ejemplos y descripciones para casos colombianos.

Although interest in ecological restoration has grown rapidly in recent years, restoration efforts have been highly empirical and have therefore been of only marginal interest to theoretical ecologists concerned with the structure and dynamics of communities. The ability to reassemble a community or ecosystem and to make it function properly actually represents a critical test of ecological understanding in the most fundamental sense. It is this idea of restoration as a technique - and even a paradigm - for ecological studies, leading in turn to improved restoration methods, that is the subject of this book.

One of the biggest threats to the survival of many plant and animal species is the destruction or fragmentation of their natural habitats. The conservation of landscape connections, where animals, plants, and ecological processes can move freely from one habitat to another, is therefore an essential part of any new conservation or environmental protection plan. In practice, however, maintaining, creating, and protecting connectivity in our increasingly dissected world is a daunting challenge. This fascinating volume provides a synthesis on the current status and literature of connectivity conservation research and implementation. It shows the challenges involved in applying existing knowledge to real-world examples and highlights areas in need of further study. Containing contributions from leading scientists and practitioners, this topical and thought-provoking volume will be essential reading for graduate students, researchers, and practitioners working in conservation biology and natural resource management.

Rapid Ecological Assessment (REA) is a methodology developed by The Nature Conservancy to provide comprehensive and reliable information about biodiversity resources in situations where time and financial resources are limited. REAs utilize a combination of remote-sensed imagery, reconnaissance overflights, field data collection, and spatial information visualization to generate useful information for conservation planning. Nature in Focus is an in-depth guide to the theory and practice of REAs, offering a detailed approach for assessing biodiversity in a rapid and integrative manner. It provides researchers with the essential tools and techniques they need to conduct an REA, and offers valuable advice about the planning and implementation aspects. The book: presents an overview of the REA methodology and sampling framework reviews all aspects of an REA: planning and management, mapping and spatial information, information management describes surveys of vegetation and fauna presents a generalized description of threat assessments explores the manner in which large amounts of data produced by different REA teams are integrated and synthesized into a cohesive set of management recommendations explains how the REA effort is documented, published, and disseminated offers a detailed REA case studyAlso included is a set of twelve color maps that describe the sequence of mapping activities in the case-study REA, along with other map examples from a range of REAs. In addition to the case study, appendixes offer a full set of REA field forms for sampling, and a model "Scope of Work" that describes the nature of work to be conducted in an REA and outlines the roles and responsibilities of the participating organizations. Nature in Focus presents the collective experience of more than ten years of REA field-testing. Conservation practitioners and biodiversity scientists who are involved with REA initiatives, along with managers, policymakers, and others involved with conservation programs will find the book a useful and nontechnical guide to an essential element of successful conservation.

• • • John Harper • • • Nature conservation has changed from an idealistic philosophy to a serious technology. Ecology, the science that underpins the technol ogy of conservation, is still too immature to provide all the wisdom that it must. It is arguable that the desire to conserve nature will in itself force the discipline of ecology to identify fundamental prob lems in its scientific goals and methods. In return, ecologists may be able to offer some insights that make conservation more practicable (Harper 1987). The idea that nature (species or communities) is worth preserv ing rests on several fundamental arguments, particularly the argu ment of nostalgia and the argument of human benefit and need. Nostalgia, of course, is a powerful emotion. With some notable ex ceptions, there is usually a feeling of dismay at a change in the sta tus quo, whether it be the loss of a place in the country for walking or rambling, the loss of a painting or architectural monument, or that one will never again have the chance to see a particular species of bird or plant.

This multi-authored volume contains peer-reviewed chapters from leading researchers and professionals in silvopastoral systems topic in Southern South America (Argentina, Chile and South Brazil). It is a compendium of original research articles, case studies, and regional overviews and summarizes the current state of knowledge on different components and aspects (pasture production, animal production, trees production, carbon sequestration, conservation) of silvopatoral systems in native forests and tree plantations. The main hypothesis of the book is that farmers have integrated tree and pasture/grassland species in their land use systems to reach higher production per unit of land area, risk avoidance, product diversification, and sustainability. These production systems also impact positively in main ecosystem processes. Management of these productive systems, Policy and Socioeconomic Aspects provide great opportunities and challenges for farmers and policy makers in our region. The book is unique on this subject in Southern South America and constitutes a valuable reference material for graduate students, professors, scientists and extensionists who work with silvopastoral systems.

This book introduces the companion modelling approach by presenting the stance that underpins it, the methods and tools used with stakeholders and the specific role of models during the process. It addresses the means to deal with the different levels of decision-making and to take into account the various power relationships. It proposes a methodology to assess the impact of the approach on the stakeholders involved in the process. The book includes 27 case studies and 7 teaching tools that describe the successful use of the approach in a variety of settings or teaching contexts. It is intended for researchers working on rural development or renewable resources management, as well as students and teachers.
