Colombia es uno de los países más ricos del planeta en especies de mariposas. La abundancia de publicaciones científicas sobre estos lepidópteros contrasta con la escasez de textos dirigidos al lector no especializado, de ahi que la Universidad del Rosario considerara oportuno editar este libro, profusamente ilustrado, que pone al alcance del lego el complejo mundo de estos insectos. La obra permite entender que es una mariposa y como se desarrolla; por que en Colombia son tan abundantes y variadas; por que la ciencia se interesa en ellas y como las afectan las amenazas contra la biodiversidad. Al documentar la belleza, variedad e importancia de las mariposas se espera ayudar a crear una mayor conciencia de la urgencia de conservar los bosques, las cañadas y los matorrales que habitan. La Universidad quiere, ademas, presentar el terreno recien adquirido para su Estacion Experimental de Campo Jose Celestino Mutis, donde, entre otras actividades, continuaran las investigaciones sobre las mariposas a cargo de la Facultad de Ciencias Naturales y Matematicas.

Lo scopo di questo libro sul problema dei cambiamenti del clima globale e quello di far parlare i dati sperimentali sul clima del passato remoto, storico e recente e farli conoscere agli interessati. Oggi si parla molto di clima senza che ci sia stata sufficiente diffusione di dati empirici facilmente reperibili in bibliografia che permettono di sviluppare un approccio essenzialmente descrittivo che puo aiutare a meglio conoscere la complessa e ancora poco conosciuta scienza del clima.A livello di divulgazione e invece in atto una specie di censura per avvalorare lipotesi della natura antropica del riscaldamento globale (Antropogenic Global Warming - AGW) come verita ufficiale non concedendo spazio ai tanti dubbi che pure ci sono e connotando un problema scientifico come un mito ideologico. Sono invece proprio i dubbi elementi essenziali per il progresso scientifico.

Publicado en 1859, El origen de las especies de Charles Darwin llegó a ser conocido como "el libro que sacudió al mundo". Su primera edición se agotó el primer día y lo mismo ocurrió con las seis versiones posteriores. Hasta el dia de hoy, la teoria de la evolucion del naturalista genera controversia. Segun Darwin, las especies compiten por la supervivencia; las que sobreviven dan lugar a la siguiente generacion, que a su vez incorpora variaciones naturales favorables y las transmite hereditariamente. Hasta su muerte, Darwin reescribio incansablemente su teoria y en cada una de las seis ediciones se incluyeron nuevas investigaciones. Esta es lo que puede considerarse su obra definitiva.Considerado todavia uno de los tratados biologicos mas innovadores y desafiantes jamas escritos, El origen de las especies, con su enfoque de los procesos evolutivos, conmociono a gran parte del mundo occidental cuando se publico en 1859. En esta nueva edicion, los lectores entraran en contacto con La obra mas importante sobre biologia jamas escrita.

El Parque Nacional Natural Gorgona (PNNG) ubicado frente a la costa Pacífica de Colombia, en jurisdicción del departamento del Cauca, es una de las principales áreas protegidas del Chocó Biogeográfico, donde la exuberante selva humeda tropical alberga una alta riqueza biologica aun desconocida para la ciencia. La presente obra es solo una muestra de la riqueza entomologica que albergan las islas Gorgona y Gorgonilla y ha sido posible gracias al aporte de 36 autores de Colombia, Mexico, Argentina, Estados Unidos e Inglaterra, quienes a lo largo de tres decadas realizaron expediciones esporadicas a estas islas para reunir en 19 capitulos aspectos de la taxonomia, morfologia, distribucion e historia natural de 259 especies de insectos pertenecientes a 16 ordenes, ademas de incluir 476 fotografias tomadas en campo y en laboratorio por reconocidos fotografos de la naturaleza e investigadores de la entomologia.Insectos de la isla Gorgona registra informacion relevante sobre insectos acuaticos, los mas primitivos y de corta vida, sobre los maestros del camuflaje que pasan inadvertidos a la espera de sus presas y sobre otros grupos que no se observan facilmente, pero que dan cuenta de su presencia dados los continuos sonidos o los destellos de luz que emiten. En cuanto a diversidad sorprenden las numerosas especies que se encontraron en la isla y que prestan importantes servicios ecosistemicos como la polinizacion, los que actuan en el control de otros insectos y los que intervienen en el reciclaje de materia organica, ademas sobresalen los insectos sociales que prestan sus servicios ambientales.Varias especies de insectos se han nominado en honor a la "isla ciencia", como se conoce a Gorgona: neuroptero Trichoscelia gorgonensis, el piojo de los libros Loneura gorgonaensis, los grillos Ripipteryx gorgonaensis y Copiphora gorgonensis, la mosca colgante Pazius gorgonensis, la abeja de las orquideas Euglossa gorgonensis, las mariposas Mesosemia zonalis gorgoniensis y Parides iphidamas gorgonae y las hormigas Leptogenys gorgona y Technomyrmex Gorgona, lo que convierten a esta isla en un importante referente entomologico para Colombia y el mundo.

Published in 1859, Charles Darwins The Origin of Species became known as The Book that Shook the World. Its first edition sold out on the first day, and the same happened with six subsequent versions. To this day, the naturalists theory of evolution is controversial. According to Darwin, species compete for survival, and those that survive give rise to the next generation, which in turn incorporates favorable natural variations and passes them on hereditarily. Until his death, Darwin tirelessly rewrote his theory, and new research was included in each of the six editions. This is what can be considered his definitive work.Still considered one of the most innovative and challenging biological treatises ever written, The Origin of Species, with its approach to evolutionary processes, shocked much of the Western world when it was released in 1859. In this new edition, readers will come into contact with the most important work on Biology ever written.

Dry stone walls the thousands of miles of stone ribbon stretching across the landscapes of the Scottish Highlands, Yorkshire Dales and Cotswolds use construction methods which have existed for thousands of years. Indeed, dry stone structures in the Orkney Islands and Ireland are even older than the Egyptian pyramids. A dry stone wall is more than a pile of rocks. It is a carefully built combination of specialized stones, each co-operating with the other to create something useful, strong and attractive. No mortar is used. The wall relies on friction and gravity, and the skill of the builder, to keep it together. The basic building principles are easily learned and this book provides step-by-step instructions to develop the skills to build many different types of wall and structure. With nearly 200 photographs and diagrams,
