Neste livro me dediquei a falar mais sobre o dromedário que é da família dos camelos, também chamado de camelo árabe ou camelo de uma corcunda. O camelo de duas corcundas é comum na Ásia. Como estive em Dubai, Egito e em Israel onde reina absoluto os dromedarios e foi com esta especie que tive bastante contato em maio de 2023. Animal domesticavel, forte, resistente, util para transporte de pessoas e carga, fornece leite para alimentaço humana e tambem carne e pele para confecço de roupas ou tendas. Sem o auxilio destes animais seria muito mais dificil a vida humana nos desertos.

El nombre de Henry David Thoreau ha llegado a nuestros días ligado a dos libros capitales para el pensamiento individualista y antiautoritario: "Ensayo sobre la Desobediencia Civil" y "Walden". Sin embargo, "Caminar" fue su obra mas popular. Concebida para una conferencia y leida en numerosas ocasiones, solo se llego a publicar postumamente en 1862. "Caminar" es un ensayo brillante, una exposicion de la filosofia del deambular, pero tambien la defensa de un pensamiento salvaje que arroje sobre nuestra conciencia una luz mas parecida a la de un relampago que a la de una vela. Un canto ecologista muy personal, su ironia y el rumbo vagabundo que por momentos toman sus reflexiones, hacen de la lectura de este libro algo tan tonificante como un paseo de buena mañana. Y no hace falta que Thoreau nos recuerde que el aburrimiento no es sino otro nombre de la domesticacion.

Los sabios y apasionados consejos de E.O. Wilson a las nuevas generaciones de científicos.Querido amigo:Después de medio siglo de enseñar a estudiantes y a jóvenes profesionales de la ciencia, he tenido el privilegio y la suerte de haber aconsejado a muchos cientos de jovenes de talento y ambiciosos. Como resultado, he acumulado un conocimiento profundo, una filosofia, en realidad, de lo que es necesario saber para tener exito en el ambito de la ciencia. Espero que puedas sacar provecho de los pensamientos y relatos que te ofrecere a lo largo de las cartas que siguen.Ante todo, y muy importante, te exhorto a permanecer en el camino que has escogido y a seguirlo tan lejos como te sea posible. El mundo te necesita, y mucho.Edmund O. WilsonReseñas: Inspirador... Deberia estar en las estanterias de todos los institutos y bibliotecas.Library JournalQuiero expresar mi agradecimiento. Gracias por recordarme, a mi y a otros miles, por que nos convertimos en cientificos. Bill Stevens, The New York Times Book ReviewEdward O. Wilson aconseja a los investigadores presentes y futuros, y comparte su sabiduria con las nuevas generaciones de cientificos. Lo hace a traves de anecdotas autobiograficas que han forjado su carrera como cientifico, sus exitos y sus fracasos, animado por la motivacion que lo ha llevado a convertirse en uno de los biologos mas importantes del mundo.En este momento de la historia de la humanidad en el que nuestra supervivencia esta mas vinculada que nunca a los conocimientos cientificos, Wilson insiste en que el talento no reside en la inteligencia matematica, sino en la pasion por plantear un problema y saber resolverlo. Desde la colision de las estrellas hasta la exploracion de los bosques tropicales y las profundidades de los oceanos, Wilson infunde en sus lectores el amor por la creatividad cientifica y el respeto por el humilde lugar que ocupa el ser humano en el ecosistema del planeta. Un libro para cientificos, jovenes y no tan jovenes, sobre la pasion y el placer por el descubrimiento.

Sugada por desmedido e indecifrável imbróglio, que transformou radicalmente sua vida, Ana Elisa se descobriu completamente sem rumo na vida. Após perder tragicamente toda sua família; ainda despreparada para qualquer tipo de trabalho que pudesse custear a propria subsistencia, passou a visualizar na carreira de modelo profissional o seu eldorado secretamente almejado; a panaceia que seria capaz de resolver de vez todos os seus problemas. Contudo, o desenfreado desejo de um dia brilhar nas passarelas no lhe permitiu perceber as armadilhas espalhadas em seu caminho e por ele se perdeu. Decepcionada com os recorrentes maus resultados colecionados, ousou considerar que a mesma quimera poderia ser realizada na pessoa de uma descendente sua e, sem ponderar a possibilidade de colher resultados to desastrosos quanto os anteriores, no se absteve de eleger a ciencia como sua possivel aliada para conquistar um futurista e insensato objetivo.

Lovecrafts short essay Cats and Dogs, which we propose to our readers today, was written on November 23, 1926, and was included in 1949 in Something About Cats and Other Pieces, a collection of fantasy, horror and science fiction short stories, poetry and essays by the great American author, published by Arkham House.Certainly Lovecraft, like other great authors who preceded him, loved cats very much. He demonstrates this fully in his essay with these words: Between dogs and cats my degree of choice is so great that it would never occur to me to compare the two. I have no active dislike for dogs, any more than I have for monkeys, human beings, tradesmen, cows, sheep, or pterodactyls; but for the cat I have entertained a particular respect and affection ever since the earliest days of my infancy. In its flawless grace and superior self-sufficiency I have seen a symbol of the perfect beauty and bland impersonality of the universe itself, objectively considered, and in its air of silent mystery there resides for me all the wonder and fascination of the unknown. The dog appeals to cheap and facile emotions; the cat to the deepest founts of imagination and cosmic perception in the human mind. It is no accident that the contemplative Egyptians, together with such later poetic spirits as Poe, Gautier, Baudelaire and Swinburne, were all sincere worshippers of the supple grimalkin. () Cats are the runes of beauty, invincibility, wonder, pride, freedom, coldness, self-sufficiency, and dainty individuality -- the qualities of sensitive, enlightened, mentally developed, pagan, cynical, poetic, philosophic, dispassionate, reserved, independent, Nietzschean, unbroken, civilised, master-class men. The dog is a peasant and the cat is a gentleman.

This volume originates in a conference session that took place at the 2018 International Council of Archaeozoology conference in Ankara, Turkey, entitled "Humans and Cattle: Interdisciplinary Perspectives to an Ancient Relationship." The aim of the session was to bring together zooarchaeologists and their colleagues from various other research fields working on human cattle interactions over time. The contributions in this volume reflect well the breadth of work being undertaken on the ancient relationship between humans and cattle across the continents of Europe, Africa and Asia, and from the late Pleistocene to postmedieval period. Almost all involve the study of archaeological cattle remains and use different zooarchaeological methods, but the combination of these approaches with that of ethnography, isotopes and genetics is also featured.

Una historia más pertinente que nunca sobre los microbios, las bacterias y cómo la enfermedad afecta nuestra vida cotidiana y a la prosperidad de nuestras sociedades. Los superhéroes en este esquema son los cientificos, bacteriologos, medicos y tecnicos medicos, que descubrieron los microbios e inventaron las vacunas para contrarrestarlos. De Kruif revela los descubrimientos ahora aparentemente simples pero realmente fundamentales de la ciencia.Un libro fascinante que describe la vida y obra de un grupo de hombres de siglos pasados que sentaron las bases para conocer y comprender el mundo de los seres vivos mas pequeños de la Tierra y nuestra relacion con ellos. La obra se inicia con la vida de Anton van Leeuwenhoek, quien reporto el primer avistamiento bajo el microscopio de seres desconocidos, abriendo a los seres humanos las puertas del mundo microbiano.Tambien trata de Louis Pasteur, quien demostro la dramatica cercania de los contactos entre esos seres y nosotros: a traves de sus estudios sobre el papel de los microorganismos en la elaboracion de cerveza y vino, dejo clara la existencia de ese mundo hasta entonces desconocido, que si bien no nos vigila en el sentido estricto del termino, si desempeña un papel fundamental en nuestras vidas.
