Many a beautiful plant cultivated to deformity, and arranged in strict geometrical beds, the whole pretty affair a laborious failure side by side with divine beauty.A Thousand-Mile Walk to the Gulf is the second book in John Muirs Wilderness-Discovery series. It is within this work that we are really given strong clues toward Muirs future trailblazing movement for environmental conservation, in such comments as The universe would be incomplete without man; but it would also be incomplete without the smallest transmicroscopic creature that dwells beyond our conceitful eyes and knowledge.Muirs walk from Indiana to Florida was conceived in order to explore and study further the flora and fauna across states. He undertakes this alone, a dangerous choice perhaps so soon after the civil war, as many characters along the way forewarn. Indeed, Muir is threatened by a robber, and we see a new side to the quiet, lowly gentleman we know as he springs into self-defence mode with lightning initiative and remarkable courage.This is not the only facet of Muirs personality that is uncovered throughout this journey. He makes reference to feeling dreadfully lonesome and poor, which is intriguing as his circumstances are self-sought: Stayed with lots of different people but preferred sleeping outside alone where possible. He spends a substantial period of time struck down with malaria, which does not come as a surprise; he was covering many miles on an unsustainably meagre diet with thirst often quenched with swamp water or not at all.Join Muir in Kentucky forests, Cumberland mountains, Florida swamps and all the elegantly described trees, plants, creatures and rocks in-between. A Thousand-Mile Walk to the Gulf teaches us as much about Muir himself as it does the ecosystems in the wilderness across those 1,000 miles.

In "A Treatise on Sheep," Ambrose Blacklock presents an exhaustive exploration of ovine management, encompassing breeding, husbandry, and the economic significance of sheep in agricultural practices. This work, framed in a didactic literary style, seamlessly integrates scientific observations with practical advice, making it a critical reference during the agricultural revolution in Britain. BlacklockAos meticulous attention to detail and clear, accessible prose render complex ideas relatable, while his comprehensive insights into the nutritional and behavioral needs of sheep establish a significant contribution to agrarian literature. Ambrose Blacklock, a noted 18th-century agronomist, was profoundly influenced by the evolving agricultural landscape of his time. His personal experiences as a farmer and observations of contemporary livestock practices informed the writing of this treatise. Blacklocks backgrounds in both farming and scientific inquiry reveal a unique perspective, positioning him as both a practitioner and a theorist in the burgeoning field of agronomy, thus enabling him to address the challenges faced by farmers in managing sheep herds.

With its blend of practical knowledge and foundational theories, Blacklocks work not only serves as a guide for modern farming techniques but also enriches our understanding of the historical context of agricultural development.

Num bosque cheio de árvores e animais, nasceu uma plantinha misteriosa, que ganhou o nome de Onze-horas, logo após ser vista por um beija-flor, que certamente já conhecia essa categoria de planta floral, diferentemente dos demais habitantes do bosque, que por nunca ter visto uma dessas, viviam curiosos para saber da vida de Onze-horas. A plantinha era adorada por todos, que por gostar tanto dela, passavam pelo local diariamente para cumprimenta-la e lhe desejar um bom dia. Ela respondia os cumprimentos de todos os seus amigos, sorridente. Onze-horas gostava de conversar com a minhoca, que era quem lhe contava todas as novidades do bosque. Todos tinham curiosidade para saber a cor, o perfume, a textura e a estaço do ano que a plantinha floria. A partir disso, quando ja estava bem proximo de ocorrer a floraço de Onze-horas, para no perder o momento exato de tal acontecimento, a melhor amiga da plantinha organizou um grupo de voluntarios para fazer uma vigilia, no intuito de saber qual o dia e a hora da floraço. Quem sera a melhor amiga da plantinha? Qual sera o dia e a hora que as flores da plantinha desabrocharam? Quem foram os animais voluntarios escolhidos para fazer a vigilia? E ainda porque a plantinha tem o nome de Onze-horas?

"The owner of a garden that is so small that but few plants can be grown in it naturally desires to confine her selection to such kinds as will be likely to give the greatest amount of bloom and require the least amount of care.At the head of the list it is quite safe to place the sweet-pea. This old and universal favorite blooms profusely and throughout the entire season if prevented from ripening seed. It is beautiful, wonderfully varied as to coloring, and so fragrant that it is almost a rival of the rose in this respect. "

LAcqua, questo elemento fondamentale per la presenza stessa della vita sulla Terra. La sua presenza in quantita enormi sul nostro pianeta, fa si che tale elemento, nonostante la sua importanza, non venga rispettato e preso, da parte delluomo, nella dovuta considerazione. Solo negli ultimi anni alcuni studiosi hanno rivolto la loro attenzione ad esso, spesso, purtroppo, non ricevendo lappoggio della scienza cosiddetta convenzionale: le loro ricerche hanno portato a conoscenza di alcune prerogative che la caratterizzano e che la pongono ai nostri occhi sotto una luce decisamente diversa.Tali studi affermano infatti che essa possiede una memoria, addirittura una sua intelligenza organizzatrice, che potrebbe aver avuto un ruolo fondante nellorganizzazione delle prime cellule e aver dato loro la scintilla vitale.In questo libro cerco di aggiungere un piccolo segmento per chiudere un cerchio che era rimasto per me aperto negli anni rispetto ad alcune certezze e ai tanti dubbi che mi hanno accompagnato fin qui, e che ultimamente risultavano un po vacillanti.

Natures creations are more sophisticated and elegant than anything humans have created. Geckos can run upside down along ceilings. Termite mounds can stay cool in the desert without air conditioning. Adapt explores how we can harness such ideas through the ground-breaking new science of biomimicry - which looks to nature to solve pressing problems in engineering and science. From the depths of the oceans to the ice sheets of the Arctic, Amina Khan talks to the researchers at the forefront of this exciting new science, who are designing everything from wind turbines to military camouflage. An entertaining eulogy to the power of evolution, this captivating book is a must read for anyone with an interest in design, nature and technology.Khan leaves no stone unturned... Readers will leave this book with a buzzing excitement. - BBC Wildlife

El cambio climático (CC) se refiere a la modificación a largo plazo del clima producida por uno o más de los siguientes factores: i) cambios internos dentro del sistema climático; ii) interacción entre componentes climaticos; iii) cambios en fuerzas externas originados por fenomenos naturales o por actividades humanas o por la interaccion de cambios naturales y humanos (World Meteorological Organization [WMO], 2012; Carvajal, 2011a). Por su parte, la variabilidad climatica (VC) se refiere a la desviacion de las estadisticas del clima de un determinado periodo (mes, estacion o año) respecto a las estadisticas a largo plazo de dicho periodo, destacando las desviaciones tipicas y los fenomenos extremos en escalas temporales y espaciales que se extienden mas alla de la escala de un fenomeno meteorologico en particular (WMO, 2012; Quintero et al., 2012). En los paises en vias de desarrollo, las microcuencas abastecedoras de acueductos rurales estan siendo afectadas por la disminucion de los servicios ecosistemicos hidrologicos (SEH) principalmente como efecto de la VC. Esta problematica genera un efecto negativo en la resiliencia de los socioecosistemas, lo cual incrementa la vulnerabilidad frente a los impactos de la VC; se afectan los recursos hidricos en cantidad y calidad, disminuye la calidad de vida de las personas y aumentan los niveles de pobreza. La VC puede incrementar los eventos extremos como sequias, olas de calor y frio o intensas lluvias. Cuando se presenta fenomeno de El Niño, el efecto sobre los caudales de los rios se expresa en reducciones y puede superar el 30% respecto al periodo de referencia. Mientras que, cuando se presenta el fenomeno de La Niña, los efectos son contrarios y pueden presentarse excedentes de caudales con un incremento desde el 12% hasta el 60%, respecto a un periodo de referencia (Instituto de Hidrologia, Meteorologia y Estudios Ambientales [IDEAM], 2015)
