The Healthy Donkey provides a fascinating background to the history of this iconic animal and introduces potential owners to everything they need to know about donkey guardianship, with useful information about diet, bedding and grooming. Those already familiar with donkeys will also find invaluable information about addressing behavioural issues using patience, kindness and bodywork using the Tellington TTouch techniques - a non-invasive system of touch and massage designed to bring about calmness, trust and confidence. Case studies show how these techniques can be used to address a variety of problems.

Believe it or not, the book of Genesis might have been the most Darwinian text in the ancient world. And throughout the opening books of Scripture, we find ideas that would also become prominent insights of the biologist Charles Darwin interlaced with the Bibles one-of-a-kind origin story. Key plot markers come to the surface again and again, driving the history of Israel and the Jesus movement forward to its cosmic completion.Biblical scholar Dru Johnson calls us beyond typical creation-versus-evolution debates to explore the conceptual worlds underlying both Scripture and evolutionary science. He points toward remarkable continuities and discontinuities between the Bibles central concerns and those of Darwin and modern scienceideas so fundamental that they can easily escape our notice.The Hebrew creation accounts, Johnson argues, weave together three key themes on the origins and development of humans and animals, themes that are also essentially Darwinian: the connection among scarcity, cooperation, and violence the fitness of creatures to their environments the genealogical aims of sexual reproduction Can the ideas of Scripture and evolutionary science be mutually illuminating? When we enter deeply into the metaphysical imagination of the biblical authors, we discover surprising ways in which the two accounts convergeand conflict.

Human beings have always wanted to become more just and more altruistic, and hoped that future generations would be morally better than the last. In the past, education, teaching, self-discipline, reading, knowledge, and moral exemplars were the main ways to achieve this. But these methods are sometimes ineffective and take a long time to work, especially in the global context where the survival of the human species is threatened by environmental disasters, pandemics, and terrorism. Some writers claim that to deal with these tremendous challenges, we need to find better ways to make people more moral. Genetics, neuroscience, and pharmacology might allow us to alter human biology to make people more generous, compassionate, and empathic. But the moral bio-enhancement project raises many questions: which human traits or dispositions should we change? Should we change emotions or reason? Does moral bio-enhancement allow for freedom? What kind of freedom does it threaten? Are we already practicing forms of moral bio-enhancement without realizing it? This book tries to answer these questions, providing a map of the debate about moral enhancement.

El comportamiento social representa un aspecto central de la conducta de los animales que se manifiesta a través del contacto físico y del uso de diversas señales de comunicación (ej., químicas, auditivas, visuales), lo que modula, entre otras, las interacciones asociadas al acceso a recursos criticos como alimento, apareamiento o refugio para evitar depredadores, y posibilitan grados variables de cuidado de las crias y distintas formas de cooperacion.El comportamiento social ha enfatizado el uso de unas pocas especies de laboratorio, asi como especies silvestres de regiones distintas de Chile y otras regiones vecinas. Este libro explora los estudios realizados en especies menos conocidas, como algunos vertebrados e invertebrados nativos de Chile, los cuales tienen un alto potencial para contribuir directamente a un desarrollo integrativo de la teoria existente.En los capitulos de este libro se aborda la diversidad de elementos del comportamiento social examinados y como dichos elementos difieren o se asemejan a aquellos de otras especies ya estudiadas. Ademas, se entrega organizadamente informacion hasta ahora dispersa sobre variados atributos del comportamiento social de especies nativas de Chile. Se enfatiza la necesidad e importancia de desarrollar aun mas el estudio cientifico del comportamiento social en especies nativas.El presente volumen busca educar a un publico no especializado sobre la singularidad y el valor cientifico del comportamiento social que caracteriza a la fauna nativa de este pais. Ademas, se espera incentivar a estudiantes en formacion e investigadores de disciplinas afines a considerar modelos sociales locales y explorar nuevos organismos de estudio para abordar problematicas novedosas e integrativas.

Desde la aparición de la agricultura hace más de 12.000 años el ser humano se ha embarcado en un ciclo recurrente de mejora y selección de numerosas especies vegetales, cuyos productos ha venido utilizando para su propia alimentacion o como materia prima para la industria.El descubrimiento del ADN y el desarrollo de las tecnicas de ingenieria genetica han dado lugar a una autentica revolucion en el campo de la mejora vegetal, desde el momento en que han permitido romper definitivamente las barreras interespecificas que restringian la transferencia de genes entre las distintas especies.En este libro se describen de forma pormenorizada las principales tecnicas de ingenieria genetica aplicadas en la actualidad a la mejora de los cultivos mas importantes, asi como las estrategias y soluciones que se han venido desarrollando en los ultimos años para lograr una optimizacion de su productividad (en terminos cuantitativos, cualitativos y fenologicos) y de las condiciones de procesamiento de los productos derivados de ellos.Asimismo, se presta una especial atencion a las propuestas encaminadas a conseguir unas practicas agricolas mas respetuosas desde un punto de vista medioambiental y, en particular, a aquellas dirigidas a la lucha contra los principales tipos de plagas que afectan a los cultivos.Finalmente, se lleva a cabo una extensa reflexion sobre las consecuencias que el desarrollo y el cultivo cada vez mas generalizado de plantas transgenicas estan teniendo para las sociedades humanas y, en particular, sobre las razones que han llevado a hacer de los organismos vegetales modificados geneticamente uno de los principales motivos de controversia en lo concerniente a la aplicacion practica de los postulados de la ingenieria genetica.

For people living in Costa Rica or visiting the country for the purpose of researching, observing, and photographing wild birds, this work is a fundamental starting point. It describes relevant data for the conservation, research, and recreational enjoyment of 108 species of birds that have a limited geographic distribution, meaning they can only be observed in this part of the world.For each of the species covered in the work, a description is included with useful data related to their habitat, behavior, distribution, and conservation status. In addition, more than 180 high-quality photographs are included, which, together with a detailed description of the anatomical aspects of each species, are intended to facilitate their identification. The data included come from field observations for more than a decade, as well as from the most up-to-date scientific literature.Also included is a section on the main regions and specific sites in Costa Rica recommended for observing endemic birds. Furthermore, the areas of endemism are characterized, ranging from southeastern Honduras to western Panama. The reader also has a registration list to record the species observed and the code of ethics for bird watchers proposed by the Ornithological Association of Costa Rica, so that the human-bird relationship is as harmonious as possible and allows the permanent enjoyment of this activity, which constitutes the main purpose of the work.

How does biotechnology touch on human destiny? What are its promises and challenges? In search for a response, the present volume turns to the thought of Hans Jonas, one of the pioneers and founding fathers of bioethics. The continued relevance of his ideas is exemplified by the way Jurgen Habermas applies them to the current debate. The chief promise of biotechnology is to increase our freedom by overcoming the limits of the human condition. The main risk of biotechnology, as both Jonas and Habermas seeit, is to diminish or outright abolish our capacity for responsibility and morality. It is argued that the greater freedom is not simply freedom from constraints but freedom for our destiny: the freedom to be the benevolent, responsible, and spontaneous authors of our lives, capable of communion and love. The touchstone for evaluating any biotechnological procedure has to be this greater freedom.
