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
Evolutionary Ecology simultaneously unifies conceptual and empirical advances in evolutionary ecology and provides a volume that can be used as either a primary textbook or a supplemental reading in an advanced undergraduate or graduate course. The focus of the book is on current concepts in evolutionary ecology, and the empirical study of these concepts. The editors have assembled a group of prominent biologists who have made significant contributions to this field. They both synthesize the current state of knowledge and identity areas for future investigation. Evolutionary Ecology will be of general interest to researchers and students in both ecology and evolutionary biology. Researchers in evolutionary ecology that want an overview of the current state of the field, and graduate students that want an introduction the field, will find this book very valuable. This volume can also be used as a primary textbook or supplemental reading in both upper division and graduate courses/seminars in Evolutionary Ecology.

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
