Durante eones, las mentes más grandes de la humanidad han carecido de respuestas confirmables a las preguntas que definen y explican el significado de la existencia humana: qué somos y qué nos creó. En Genesis, el celebre biologo Edward O. Wilson examina la historia evolutiva y nos ofrece una descripcion reveladora de los profundos origenes de la sociedad. Al afirmar que las creencias religiosas y las cuestiones filosoficas se pueden reducir a componentes puramente geneticos y evolutivos, y que tanto el cuerpo como la mente humanos poseen una base fisica que obedece a las leyes de la fisica y la quimica, Genesis demuestra que el unico modo que tenemos para comprender el comportamiento humano es estudiar las diversas historias evolutivas de las especies no humanas.Wilson demuestra que se han observado al menos diecisiete (entre ellas la rata topo desnuda africana y el camaron que deja sus huevos en una esponja) que han desarrollado sociedades avanzadas basadas en niveles de altruismo y la cooperacion parecidos a los humanos. Ya sea escribiendo sobre dipteros que bailan como acrobatas o bancos de anchoas que se apiñan como medida de proteccion para parecer un pez gigantesco, Edward O. Wilson elabora una obra innovadora sobre la teoria evolutiva con las observaciones biologicas y humanisticas por las que es conocido y admirado.

Steven Weinberg, premio Nobel de Física por su contribución a la unificación de dos de las fuerzas básicas de la naturaleza -la fuerza débil y el electromagnetismo-, aborda en este libro la gran aventura intelectual de nuestro tiempo: la busqueda de una teoria final, aquella en la que todas las preguntas fundamentales hallarian respuesta sin requerir una explicacion en terminos de otros principios. Weinberg, que no solo es un gran fisico sino un excelente divulgador, nos explica de manera llana y comprensible la idea de esta teoria final, los pasos que han conducido hacia ella ylos obstaculos que encuentra, dejandonos en la frontera de esa tierra prometida.

R.A. D'Inverno There is little doubt that Einstein's theory of relativity captures the imagination. Not only has it radically altered the way we view the universe, but the theory also has a considerable number of surprises in store. This is especially so in the three main topics of current interest that this book reaches, namely: black holes, gravitational waves, and cosmology. The main aim of this textbook is to provide students with a sound mathematical introduction coupled to an understanding of the physical insights needed to explore the subject. Indeed, the book follows Einstein in that it introduces the theory very much from a physical point of view. After introducing the special theory of relativity, the basic field equations of gravitation are derived and discussed carefully as a prelude to first solving them in simple cases and then exploring the three main areas of application. Einstein's theory of relativity is undoubtedly one of the greatest achievements of the human mind. Yet, in this book, the author makes it possible for students with a wide range of abilities to deal confidently with the subject. Based on the author's fifteen years experience of teaching this subject, this is achieved by breaking down the main arguments into simple logical steps. The book includes numerous illustrative diagrams and exercises (of varying degrees of difficulty), and as a result this book makes an excellent course for any student coming to the subject for the first time.

This book includes descriptive keys for identifying every stage of all the species of ticks reported in Europe and northern Africa. It includes descriptive texts on the ecology and prominent features of each species, together with ink illustrations and distribution maps of more than 60 species of hard and soft ticks. The text for each species was prepared by specialists, the illustrations were made especially for this book and the maps were compiled on the basis of more than 40 years of records. This book is the first to offer keys for more than 60 species of ticks (both immature and adult) in the target territory. It also includes supplementary information with bibliographical details for each species.

Having been the fourth largest lake on the globe roughly 50 years ago today the Aral Sea no longer exists Human activities caused its desiccation and the formation of a huge new desert the Aralkum which can be regarded as one of the greatest ecological catastrophes and at the same time the largest primary succession experiment of mankind This volume brings together the results of international and interdisciplinary long term studies on the new desert ecosystem and is divided into four main sections The first section provides an overview of the physical characteristics of the area and covers geological pedological geomorphological and climatological aspects and their dynamics especially dust storm dynamics The second focuses on the biotic aspects and highlights the spatial and temporal patterns of the flora and fauna In the third section studies and projects aiming to combat desertification by phytomelioration and to develop strategies for the conservation of biodiversity are presented The book is rounded off with a section providing a synthesis and conclusions

The birds, animals, insects, trees and plants encountered by the majority of the worlds people are those that survive in, adapt to, or are introduced to, urban areas. Some of these organisms give great pleasure; others invade, colonise and occupy neglected and hidden areas such as derelict land and sewers. Urban areas have a high biodiversity and nature within cities provides many ecosystem services including cooling the urban area, reducing urban flood risk, filtering pollutants, supplying food, and providing accessible recreation. Yet, protecting urban nature faces competition from other urban land uses.The Handbook of Urban Ecology analyses this biodiversity and complexity and provides the science to guide policy and management to make cities more attractive, more enjoyable, and better for our own health and that of the planet. This Handbook contains 50 interdisciplinary contributions from leading academics and practitioners from across the world to provide an in-depth coverage of the main elements of practical urban ecology. It is divided into six parts, dealing with the philosophies, concepts and history of urban ecology; followed by consideration of the biophysical character of the urban environment and the diverse habitats found within it. It then examines human relationships with urban nature, the health, economic and environmental benefits of urban ecology before discussing the methods used in urban ecology and ways of putting the science into practice.The Handbook offers a state-of the art guide to the science, practice and value of urban ecology. The engaging contributions provide students and practitioners with the wealth of interdisciplinary information needed to manage the biota and green landscapes in urban areas.
