Five stunningly large forests remain on Earth: the Taiga, extending from the Pacific Ocean across all of Russia and far-northern Europe; the North American boreal, ranging from Alaskas Bering seacoast to Canadas Atlantic shore; the Amazon, covering almost the entirety of South Americas bulge; the Congo, occupying parts of six nations in Africas wet equatorial middle; and the island forest of New Guinea, twice the size of California.These megaforests are vital to preserving global biodiversity, thousands of cultures, and a stable climate, as economist John W. Reid and celebrated biologist Thomas E. Lovejoy argue convincingly in Ever Green. Megaforests serve an essential role in decarbonizing the atmospherethe boreal alone holds 1.8 trillion metric tons of carbon in its deep soils and peat layers, 190 years worth of global emissions at 2019 levelsand saving them is the most immediate and affordable large-scale solution to our planets most formidable ongoing crisis.Reid and Lovejoy offer practical solutions to address the biggest challenges these forests face, from vastly expanding protected areas, to supporting Indigenous forest stewards, to planning smarter road networks. In gorgeous prose that evokes the majesty of these ancient forests along with the people and animals who inhabit them, Reid and Lovejoy take us on an exhilarating global journey.

An absolute treasure trove of sound advice and historical detail Katherine May A delightful and a profound meditation on the variety of human experience Ian Mortimer Lara Maiklem is a phenomenon She elevates trudging around in the mud to an epic gallivant through our past Dan SnowFor over two decades Lara Maiklem has been scouring the banks of the tidal Thames looking for objects lost or discarded that tell forgotten stories In this charming sequel to the bestselling Mudlarking Lara widens her search beyond the river and reflects on life lived post pandemic reminding us that it s possible to draw meaning in the most unlikely of places As she searches the foreshore through the changing seasons she is at times aided by the gentle illumination of the falling winter sun or hindered by bright summer skies and lashing rain Yet by working in harmony with the unpredictable terrain she finds solace in aligning with the elements and uncovering the treasures that are bestowed by the tide From medieval pilgrim badges and Tudor love tokens to Georgian wig curlers and Victorian pottery each passing day unearths ordinary and extraordinary objects that tell the rich story of London s past and its inhabitants A Mudlarking Year is a gentle ode to nature history and

The astonishing story of how animals use medicine and what it can teach us about healing ourselvesAges before the dawn of modern medicine wild animals were harnessing the power of nature s pharmacy to heal themselves Doctors by Nature reveals what researchers are now learning about the medical wonders of the animal world In this visionary book Jaap de Roode argues that we have underestimated the healing potential of nature for too long and shows how the study of self medicating animals could impact the practice of human medicine Drawing on illuminating interviews with leading scientists from around the globe as well as his own pioneering research on monarch butterflies de Roode demonstrates how animals of all kinds from ants to apes from bees to bears and from cats to caterpillars use various forms of medicine to treat their own ailments and those of their relatives We meet apes that swallow leaves to dislodge worms sparrows that use cigarette butts to repel parasites and bees that incorporate sticky resin into their hives to combat pathogens De Roode asks whether these astonishing behaviors are learned or innate and explains why now more than ever we need to apply the lessons from medicating animals it can pave the way for healthier livestock more susta

teeming with fascinating and enlightening insights ObserverA narrative investigation into the new science of plant intelligence and sentience from National Association of Science Writers Award winner and Livingston Award finalist Zoe Schlanger Look at the green organism across the room or through the window the potted plant or the grass or a tree Think how a life spent constantly growing yet rooted in a single spot comes with tremendous challenges To meet them plants have come up with some of the most creative methods for surviving of any living thing us included Many are so ingenious that they seem nearly impossible Did you know plants can communicate when they are being eaten allowing nearby plants to bolster their defences They move and that movement stops when they are anaesthetised They also use electricity for internal communication They can hear the sounds of caterpillars eating Plants can remember the last time they have been visited by a bee and how many times they have been visited so they have a concept of time and can count Plants can not only communicate with each other they can also communicate with other species of plants and animals allowing them to manipulate animals to defend or fertilise them So look again at the potted plant or

¿Cómo han evolucionado las matemáticas a lo largo de los siglos? ¿En qué medida el comportamiento humano y los cambios en los estilos de vida pueden depender de ellas? ¿Hasta qué punto nuestra comprensión del universo toma forma a partir de ese tipo de conocimiento? En este libro extraordinario, Richard Mankiewicz cuenta la historia de esa actividad intelectual a través de las distintas culturas y civilizaciones, demostrando de ese modo que no se trata en absoluto de una ocupación exclusiva de filósofos, sacerdotes y científicos, sino que, de una forma u otra, afecta a la totalidad de las áreas del conocimiento humano. En cualquier momento de la historia podemos encontrar demostraciones de que las matemáticas han desempeñado y desempeñarán un papel trascendental: los mapas utilizados para el comercio y los viajes, la obsesión por el movimiento de los cuerpos celestes, la utilización de la perspectiva en el arte y la visión... En cualquier caso, una serie de fascinantes imágenes jalona inesperadamente el camino seguido por esta disciplina, desde los manuscritos medievales al arte de Dalí o Duchamp, de la austera belleza de las tablillas babilónicas a la delicada complejidad de las figuras generadas por ordenador. Mankiewicz utiliza estos referentes para elaborar un texto tan complejo como accesible, apasionante en su inmensa erudición, que conduce al lector de la mano hacia épocas y territorios que siempre quiso conocer: las civilizaciones china e hindú, la Europa medieval, las revoluciones científica y digital... Y el resultado es una maravillosa conjunción de historia, biografía y ciencia que arroja definitivamente luz sobre un universo hasta ahora inquietante y desconocido.

Una de las metas principales que se tenían al preparar la octava edición de este libro era aumentar la claridad de los análisis. Se deseaba capacitar al estudiante para que comprendiera con más facilidad los conceptos presentados, pero no se quería sacrificar la corrección matemática que ha sido de capital importancia para el buen logro de este texto. Al mejorar las explicaciones de los conceptos más difíciles e incluir comentarios paso a paso de las soluciones de los ejemplos, se ha avanzado en la meta de ayudar al estudiante conservando el rigor matemático.

Robert R. Johnson y Patricia Kuby, dos de los más respetados profesores de estadística, crearon el concepto de "lo esencial", pensando en un enfoque muy práctico de la estadística; y no sólo eso, tambien esta diseñado para el estudiante que no tiene una amplia base de estudios matematicos. Para esto, los autores presentan todo el tiempo una clara relacion entre los conceptos estudiados y las experiencias cotidianas en el mundo de hoy.

N. Katherine Hayles investiga en este libro los paralelismos entre la literatura y la teoría crítica contemporáneas y el nuevo campo interdiscisciplinario conocido como ciencia del caos. Tanto en el discurso cientifico como en el literario la autora encuentra nuevas interpretaciones del caos, que ya no es considerado como desorden, sino como un locus de maxima informacion y complejidad. Hayles muestra que el nuevo paradigma del caos incluye elementos que ya eran evidentes en la teoria literaria y la literatura antes de llegar a destacarse en las ciencias naturales. Afirma que tales similitudes entre las ciencias naturales y las ciencias humanas no son el resultado de influencias directas, sino de la existencia de raices en una matriz cultural comun.Hayles rastrea la evolucion del concepto del caos y evalua la obra de teoricos como Prigogine, Feigenbaum y Mandelbrot, para quienes el caos supone un universo abierto e imprevisible donde el conocimiento y los modelos cientificos no pueden agotar nunca las posibilidades de lo real. Pero esta vision no implica que los cientificos hayan renunciado a su busqueda de explicaciones totalizadoras para los fenomenos naturales, porque se entiende que el caos contiene su propia forma de orden.La autora examina las estructuras y los temas del desorden en La educacion de Henry Adams, en El cuaderno dorado de Doris Lessing y en algunas obras de Stanislaw Lem, y muestra que los trabajos de los teoricos posestructuralistas incorporan caracteristicas fundamentales de la teoria del caos, como el interes por vincular los sitios locales con las estructuras globales; la comprension de que en los sistemas complejos causas pequeñas pueden producir efectos masivos ; y el reconocimiento de que los sistemas complejos pueden ser tanto deterministas como imprevisibles.Este libro enriquece los actuales debates entre teoricos del caos, criticos e historiadores de la cultura, teoricos y criticos literarios interesados en la literatura de los siglos XIX y XX, investigadores en el campo de la dinamica no lineal y todos aquellos que se ocupan de la relacion entre ciencia y cultura.
