Paperback. Condición: Very Good. First Edition. Illustrated with a few charts, octavo, pp xxii, 452, upper corners slightly bruised, otherwise very clean internally, paperback, the upper corner slightly creased. ["Habitat fragmentation and global climate change are the two major environmental threats to the persistence of species and ecosystems. The probability of a species surviving such changes is strongly dependent on its ability to track shifts in the environmental, either by moving between patches of habitat or by rapidly adapting to local condition. These 'solutions' to problems posed by environmental change depend on dispersal propensity, motivating our desire to better understand this important behavior. This book is a comprehensive overview of the new developments in the study of dispersal and the state-of-the-art research on the evolution of this trait. The causes, mechanisms, and consequences of dispersal at the individual, population, and species levels are considered. The promise of new techniques and models for studying dispersal, drawn from molecular biology and demography is explored. Perspectives on the study of dispersal are offered from evolution, conservation biology, and genetics. Throughout the book, theoretical approaches are combined with empirical data, and examples are included from as wide a range of species as possible."].

Rústica (Tapa blanda). Condición: Bien. Estado de la sobrecubierta: Sin cubierta. Materia: Historia universal. Características físicas: Restos de forro de plástico en el lomo. El lomo tiene una pequeña rotura en la parte inferior. Ubicación: R29B2-12. El volumen 10 de la colección Historia Universal Siglo Veintiuno, titulado La Alta Edad Media y redactado por el historiador belga Jan Dhondt, ofrece una síntesis clara y documentada del periodo comprendido entre los siglos V y XI, etapa fundamental para la configuración del mundo europeo posterior a la caída del Imperio romano. Publicado por Ediciones Castilla en 1971, este tomo aborda como materia principal la historia medieval, con especial atención a los procesos de transición cultural, institucional y económica que definieron la Alta Edad Media. Dhondt analiza el impacto de las invasiones germánicas, la formación de los reinos romano-bárbaros, la consolidación del cristianismo como fuerza estructurante y la articulación de nuevas formas de poder y sociabilidad, culminando en el surgimiento del sistema feudal y el renacimiento carolingio. El enfoque temático destaca las continuidades y rupturas con respecto al mundo antiguo, así como la progresiva formación de una Europa cristiana occidentalizada. A través de una prosa didáctica y fundamentada, el autor integra perspectivas políticas, culturales, económicas y religiosas, ofreciendo una visión de conjunto útil tanto para especialistas como para lectores que buscan una introducción rigurosa a esta etapa histórica. Este volumen resulta especialmente valioso para estudiantes de historia, medievalistas y docentes interesados en los orígenes de la civilización europea. LIBRO.

Paperback. Condición: Near Fine. Paperback in near fine condition, bumped corner. Inscribed by author on half title page. In nature there exist three main types of biotic interactions between individuals of different species: competition, predation, and mutualism. All three exert powerful selection pressures, and all three shape communities. However, the question of how important interspecific competition in nature really is remains controversial and unresolved. This book provides a critical and exhaustive review of the topic. Although the examples are limited mostly to birds (interspecific competition and community structure have been exhaustively studied in this animal group, and a lot of experimental data are available), the conclusions reached have a far broader relevance to population ecologists in general. The book reasons that the coexistence of species is the result of both past and presently on-going interspecific competition. Furthermore, understanding the importance of interspecific competition in natural systems will be increasingly important when modelling the effects of climate change on populations.

Condición: Good. xxi, 452, text figs. . PB. Corner bumped. Crease to corner or rear wrapper. Good. The ability of species to migrate that has interested ecologists for many years. Now that so many species and ecosystems face major environmental change, the ability of species to adapt to these changes by dispersing, migrating, or moving between different patches of habitat can be crucial to ensuring their survivial. This book provides a timely and wide-ranging overview of the study of dispersal and incorporates much of the latest research. The causes, mechanisms, and consequences of dispersal at the individual, population, species and community levels are considered. The potential of new techniques and models for studying dispersal, drawn from molecular biology and demography, is also explored. Perspectives and insights are offered from the fields of evolution, conservation biology and genetics. Throughout the book, theoretical approaches are combined with empirical data, and care has been taken to include examples from as wide a range of species as possible. [9780198506591].
