Download or read book MANUAL DE T CNICAS DE MONTA A E INTERPRETACI N DE LA NATURALEZA Bicolor written by Javier A. Melendo Soler and published by Editorial Paidotribo. This book was released on 2006-08-31 with total page 318 pages. Available in PDF, EPUB and Kindle. Book excerpt: Este libro está estructurado en doce capítulos, con numeroso soporte gráfico, que recogen de la forma más compleja posible los aspectos que debemos conocer al adentrarnos en el medio natural. El orden y la composición de los capítulos son los siguientes: Orientación y cartografía Se describen los sistemas de referencia y las técnicas de orientación sustentadas en ellos. La utilización de mapas, brújulas y otros instrumentos, necesarios para planificar nuestros itinerarios. La interpretación de los mapas de los lugares por los que nos desplazamos es el soporte principal para el desarrollo de nuestra excursión y el mejor medio para no extraviarnos. Técnicas de progresión por senderos e itinerarios de media y baja montaña El senderismo, la media montaña, la alta montaña sin necesidad de utilizar vías de escalada, forman el contenido de este capítulo. Caminar por diferentes tipos de terreno y conocer el material adecuado para la actividad. ¿Qué debemos llevar puerto?, ¿qué material debo transportar? Son algunas de las preguntas que todos nos hacemos y que tratamos de contestar. El cálculo de la duración de la excursión, a sí como sus períodos de pausa, nos obligará a establecer tiempos en función de los desniveles o de la longitud por correr. Meteorología Gracias a los medios informativos actuales, no deberíamos comenzar nuestras actividades sin informarnos de la meteorología prevista. La interpretación de ésta no termina con la televisiva imagen de unas nubes encima de un mapa. El conocimiento de la dinámica atmosférica y la interpretación de los signos naturales evolutivos permitirá evitarnos más de una situación comprometido, o al menos estar preparados para enfrentarnos a ella. Se expone un detallado estudio sobre las temperaturas, las precipitaciones y la presión atmosférica. Interpretación del paisaje La mirada requiere un adiestramiento para contemplar. Diferentes personas pueden acercarse a un mismo paisaje y tener percepciones diferentes. El presente capitulo pretende dotar al observador de un bagaje instrumental que le permita interpretarlo. Los métodos de estudio utilizados serán: las unidades del paisaje, su caracterización, su dinámica propia de un terreno vivo y su valoración tanto individual como grupal. Organización de campamentos y travesías de media montaña Cuando nuestra actividad ocupa más de un día, se hace necesaria la acampada. La organización de un campamento fijo, o un campamento itinerante, está sometida a unas condiciones y a una normativa que es imprescindible conocer. Desde el respeto al medio natural, deberemos elegir las ubicaciones más seguras para la acampada. El equipo de acampada que debemos trasportar, tanto personal, como colectivo, complementa a los materiales necesarios para el desarrollo de la actividad. Senderos y caminos El auge del senderismo ha provocado la creciente señalización de muchos caminos. Son muchas las zonas que están incentivando el uso de los caminos tradicionales, o incluso abriendo nuevos caminos. La autora nos acerca a la actual normativa y regulación de estos senderos. La interpretación del medio ambiente Los efectos resultantes de la modificación que el hombre imprime al medio natural condicionan su protección. Los contenidos de este capítulo se orientas hacia las pautas de conducta que debemos adoptar. El conocimiento de la normativa medioambiental en nuestro país, así como la evaluación del impacto ambiental, nos ayudarán a conseguir este objetivo. Seguridad en montaña, utilización del material de seguridad y técnicas básicas de escalada en roca La progresión en la montaña con seguridad requiere conocer las normas que debemos cumplir en caso de un accidente, o para solicitar socorro. El conocimiento de técnicas básicas de escalada, así como el material necesario para éstas, es importante tanto si nuestra actividad es la escalada, como si a lo largo de nuestro recorrido tenemos que utilizar, para nuestra seguridad, cuerdas u otro material auxiliar. Nudos, anclajes y maniobras con cuerdas En continuidad con las maniobras de seguridad, se describen los principales nudos y los anclajes, tanto naturales como artificiales. Las maniobras con cuerdas son el complemento imprescindible en terrenos escarpados, o con dificultades naturales infranqueables. El rápel, las técnicas de ascenso, las de aseguramiento, auto-rescate, o el trasporte de accidentados, forma parte de éstas. Supervivencia La prudencia y nuestra preparación colaboran a evitar los accidentes. L sentido común y algunos conocimientos básicos pueden ser imprescindibles ante situaciones limite. Saber utilizar los recursos naturales y propios, para obtener agua, alimentos, o bien procurarnos un refugio, son algunos de los apartados tratados en este capítulo. Preparación física y nutrición para la realización de actividades en la naturaleza El acercamiento a unas actividades más exigentes requiere alcanzar un adecuado nivel de condición física. Si no queremos que nuestras excursiones se conviertan en una tortura, deberá estar en consonancia nuestra capacidad física con los objetivos a alcanzar. El autor describe las normas básicas para el entrenamiento de excursionistas y montañeros, así como los sistemas de obtención de la energía, en los que se sustenta una nutric8ón e hidratación adecuadas. Medidas preventivas y primeros auxilios en el medio natural Se recoge un amplio abanico de las lesiones y accidentes que pueden darse en el medio natural. La necesidad de una rápida instauración de medidas de auxilio, así como una correcta aplicación de éstas, nos obliga a ser insistentes en su conocimiento. La lejanía de cualquier centro sanitario hace todavía más necesario que las personas que se desplazan por la naturaleza conozcan a fondo las maniobras de primeros auxilios.

Download or read book Capybara written by José Roberto Moreira and published by Springer Science & Business Media. This book was released on 2012-08-16 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: The capybara is the neotropical mammal with the highest potential for production and domestication. Amongst the favorable characteristics for domestication we can list its high prolificacy, rapid growth rate, a herbivorous diet, social behavior and relative tameness. The genus (with only two species) is found from the Panama Canal to the north of Argentina on the east of the Andes. Chile is the only country in South America where the capybara is not found. The species is eaten all over its range, especially by poor, rural and traditional communities engaged in subsistence hunting. On the other hand, in large urban settlements wildlife is consumed by city dwellers as a delicacy. The sustainable management of capybara in the wild has been adopted by some South American countries, while others have encouraged capybara rearing in captivity.

Download or read book Banana Genomics and Transgenic Approaches for Genetic Improvement written by Sukhada Mohandas and published by Springer. This book was released on 2016-09-08 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bananas and plantains are among the most important food and cash crops in the world. They are cultivated in more than 135 countries, across the tropics and subtropics, with an annual global production of ca. 130 million metric tonnes. Though bananas are one of the most important components of food security in many developing countries, banana production is threatened by both abiotic and biotic stresses. These include a wide range of diseases and pests, such as bunchy top virus, burrowing nematodes, black Sigatoka or black leaf streak, Fusarium wilt, etc. In recent years, considerable progress has been made and several biotechnological and genomic tools have been employed to help understand and unravel the mysterious banana genome. Molecular and genomic studies have helped to decipher the Musa genome and its evolution. Genetic linkage map and whole genome sequencing of both Musa acuminata and Musa balbisiana (progenitors of cultivated banana) have completely changed the way of thinking and the approach on banana crop improvement. Whole-genome sequencing has helped to improve the selection of quantitative traits such as yield, as well as the selection of optimal parents for developing required hybrids in breeding programs. Gene isolation and the analysis of mutants have helped in the characterization of genes of agronomic value and the associated regulatory sequences. With the advent of molecular markers and new statistical tools, it is now possible to measure the diversity, identify genes and useful alleles linked to important agronomic traits. Further these alleles can be incorporated into cultivars through marker assisted selection or through transgenic approach. Transgenic approaches are potential tools for direct transfer of these genes into popular cultivars, which are generally not amenable for conventional breeding techniques, in specific with crops such as bananas which are sterile, triploid and heterozygous thereby making it difficult to reconstruct the recurrent genotypes in banana. Transgenic techniques thus have helped overcome the difficulty of working with sterile, triploid banana crop. In the last five years, enormous amount of new information and techniques have been generated for banana. A comprehensive book entitled “Banana: Genomics and Transgenic Approaches for Genetic improvement” on banana genomics, latest transgenic technologies and tools available for improved crop development in banana will address all these requirements.

Download or read book High Altitude Primates written by Nanda B. Grow and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 368 pages. Available in PDF, EPUB and Kindle. Book excerpt: The basic goal of the volume is to compile the most up to date research on how high altitude affects the behavior, ecology, evolution and conservation status of primates, especially in comparison to lowland populations. Historically, the majority of primate studies have focused on lowland populations. However, as the lowlands have been disappearing, more and more primatologists have begun studying populations located in higher altitudes. High altitude populations are important not only because of their uniqueness, but also because they highlight the range of primate adaptability and the complex variables that are involved in primate evolution. These populations are good examples of how geographic scales result in diversification and/or speciation. Yet, there have been very few papers addressing how this high altitude environment affects the behavior, ecology, and conservation status of these primates. ​
