Este libro representa el segundo aporte a la colección de "Modelos y Métodos Cuantitativos en Ciencias Ecológicas y Ambientales", iniciada por dos de los mismos autores con su libro anterior Dinámica y Manejo de Poblaciones: Modelos Unidimensionales (Acevedo y Raventós, 2003). La idea fundamental de este segundo volumen es presentar una serie de modelos que ilustran cómo se incorpora el espacio a los modelos de dinámica de poblaciones y se introduce la dinámica de las comunidades ecológicas. Josep Raventós es profesor titular de Ecología en la Universidad Alicante y especialista en Ecología de Poblaciones. José G. Segarra, integrante del programa doctoral de la UA, es especialista en Ecología Teórica. Miguel F. Acevedo es catedrático del Departamento de Geografía y Ciencias Aplicadas de la Universidad North Texas, USA, y especialista en Ingeniería Medioambiental.

Every day, biologists in parkas, raincoats, and rubber boots go into the field to capture and mark a variety of animal species. Back in the office, statisticians create analytical models for the field biologists' data. But many times, representatives of the two professions do not fully understand one another's roles. This book bridges this gap by helping biologists understand state-of-the-art statistical methods for analyzing capture-recapture data. In so doing, statisticians will also become more familiar with the design of field studies and with the real-life issues facing biologists. Reliable outcomes of capture-recapture studies are vital to answering key ecological questions. Is the population increasing or decreasing? Do more or fewer animals have a particular characteristic? In answering these questions, biologists cannot hope to capture and mark entire populations. And frequently, the populations change unpredictably during a study. Thus, increasingly sophisticated models have been employed to convert data into answers to ecological questions. This book, by experts in capture-recapture analysis, introduces the most up-to-date methods for data analysis while explaining the theory behind those methods. Thorough, concise, and portable, it will be immensely useful to biologists, biometricians, and statisticians, students in both fields, and anyone else engaged in the capture-recapture process.

Until recently community ecology& a science devoted to understanding the patterns and processes of species distribution and abundance& focused mainly on specific and often limited scales of a single community. Since the 1970s, for example, metapopulation dynamics& studies of interacting groups of populations connected through movement& concentrated on the processes of population turnover, extinction, and establishment of new populations. 'Metacommunities' takes the hallmarks of metapopulation theory to the next level by considering a group of communities, each of which may contain numerous populations, connected by species interactions within communities and the movement of individuals between communities. In examining communities open to dispersal, the book unites a broad range of ecological theories, presenting some of the first empirical investigations and revealing the value of the metacommunity approach. The collection of empirical, theoretical, and synthetic chapters in 'Metacommunities' seeks to understand how communities work in fragmented landscapes. Encouraging community ecologists to rethink some of the leading theories of population and community dynamics, 'Metacommunities' urges ecologists to expand the spatiotemporal scales of their research.
