Book Description
El venado cola blanca (Odocoileus virginianus) es un animal silvestre que habita prácticamente en todo el Continente Americano. En México, prácticamente en todo el país, excepto en la Península de Baja California. Tiene alrededor de 500,000 años en su forma actual y 20 millones de evolución. Económicamente, es considerado el trofeo de cacería mayor más importante en todo el mundo. Presenta dimorfismo sexual al mostrar diferencias de forma, coloración y tamaño entre machos y hembras. Tiene hábitos crepusculares, pueden encontrarse en grupos de 2 a 6 y hasta 15 individuos. Tiene un órgano conocido como vomeronasal. Es un órgano auxiliar del sentido del olfato que le da al venado un sexto sentido y que es usado principalmente durante el apareamiento, para detectar sustancias secretadas por las hembras. Tiene hígado, pero no tiene vesícula biliar. Su carne es magra y bajo contenido de colesterol. Es rumiante y herbívoro. Forrajea la vegetación para consumir hojas, brotes, frutos y semillas, así como hongos. El hábitat se encuentra prácticamente en todos los hábitats, siempre que estos le proporcionen suficiente refugio y alimento. No es común en las partes más secas y abiertas del matorral xerófilo ni en las partes más densas y húmedas del bosque tropical perennifolio. Los microbios en el rumen, además de que sintetizan las vitaminas hidrosolubles del complejo B y la K que es liposoluble, hacen posible que el venado obtenga nutrientes que no son disponibles a los animales no rumiantes y convierten nitrógeno no proteico a proteína bacteriana, rica en aminoácidos.

Book Description
Landscape Ecology is an emerging science of gaining momentum over the past few decades in the scientific as well as in the planning-management worlds. Although the field is rooted in biology and geography, the approaches to understanding the ecology of a landscape are highly divers. This hybrid vigor provides power to the field. One can no longer view a local ecosystem or land use in isolation from global areas and time frames. The surrounding landscape mosaic and the flows and movements in a landscape must be considered, especially the linkage between humans requiring resources provided by nature, the constraints on their use as well as the responding landscape.

Book Description
A definitive guide to the depth and breadth of the ecological sciences, revised and updated The revised and updated fifth edition of Ecology: From Individuals to Ecosystems – now in full colour – offers students and practitioners a review of the ecological sciences. The previous editions of this book earned the authors the prestigious ‘Exceptional Life-time Achievement Award’ of the British Ecological Society – the aim for the fifth edition is not only to maintain standards but indeed to enhance its coverage of Ecology. In the first edition, 34 years ago, it seemed acceptable for ecologists to hold a comfortable, objective, not to say aloof position, from which the ecological communities around us were simply material for which we sought a scientific understanding. Now, we must accept the immediacy of the many environmental problems that threaten us and the responsibility of ecologists to play their full part in addressing these problems. This fifth edition addresses this challenge, with several chapters devoted entirely to applied topics, and examples of how ecological principles have been applied to problems facing us highlighted throughout the remaining nineteen chapters. Nonetheless, the authors remain wedded to the belief that environmental action can only ever be as sound as the ecological principles on which it is based. Hence, while trying harder than ever to help improve preparedness for addressing the environmental problems of the years ahead, the book remains, in its essence, an exposition of the science of ecology. This new edition incorporates the results from more than a thousand recent studies into a fully up-to-date text. Written for students of ecology, researchers and practitioners, the fifth edition of Ecology: From Individuals to Ecosystems is anessential reference to all aspects of ecology and addresses environmental problems of the future.

Book Description
For one or two semester courses in Introductory Biology targeting non- and mixed majors. The goal of this text is to provide an engaging and easy to use book with an innovative and interactive media program. It achieves a unique balance in emphasizing concepts without sacrificing scientific accuracy. The new MediaTutor, found at the end of each chapter, integrates the text and media by providing a brief description of the CD or WEB activity and the time requirement for completion. In creating the book and the media package, the authors and Prentice Hall reached out to the biology community - involving educators from around the country to help address the diverse needs of todays students. How do you engage your students and help make biology relevant to them? *NEW - Chapter-opening Case Studies and chapter-ending Case Studies Revisited - Includes Did Dinosaurs Die from Lack of Sunlight? from the chapter on Photosynthesis and Teaching an Old Grain New Tricks from the chapter on Biotechnology. Provides an innovative framework for students to learn and make connections between biological concepts and processes. *Earth Watch/Health Watch essays - Covers biodiversity, ozone depletion/pre
