Pocos podían sospechar que la caída del mundo clásico se iba a precipitar sobre la cuenca del Mediterráneo durante un periodo medieval que llegó a durar mil años. Las luchas larvadas por el poder, las migraciones, las nuevas ideas religiosas y las invasiones bárbaras hicieron el resto. En esta obra, Ramón Sanchis, analiza el desarrollo del conocimiento a lo largo de toda la Edad Media y en la que Al Ándalus fue clave en la conservación y recuperación de la cultura clásica. Se profundizará en los acontecimientos que marcaron a la sociedad y la cultura de la época como la caída del Imperio romano de Occidente, la evolución del cristianismo primitivo, la gnosis, las Escuelas de ...
Un viaje de vacaciones a Italia será el desencadenante que ponga al descubierto un sorprendente misterio. John Leslie Hotson, un tenaz investigador, especialista en el teatro de la época isabelina, adquiere en un anticuario de Padua unas cartas manuscritas de autor desconocido. En ellas descubre unas citas sobre el asesinato de un escritor inglés que implica al servicio secreto de Su Majestad. En Londres, con la ayuda del investigador Calvin Hoffman y la documentalista Sophie Anniston, comenzará a indagar el contenido de las cartas. No aparecen nombres. No hay firmas.

The Mediterranean's Iron Age period was one of its most dynamic eras. Stimulated by the movement of individuals and groups on an unprecedented scale, the first half of the first millennium BCE witnesses the development of Mediterranean-wide practices, including related writing systems, common features of urbanism, and shared artistic styles and techniques, alongside the evolution of wide-scale trade. Together, these created an engaged, interlinked and interactive Mediterranean. We can recognise this as the Mediterranean's first truly globalising era. This volume introduces students and scholars to contemporary evidence and theories surrounding the Mediterranean from the eleventh century until the end of the seventh century BCE to enable an integrated understanding of the multicultural and socially complex nature of this incredibly vibrant period.
I Twenty-five years ago, at the Conference on the Comparative Reception of Darwinism held at the University of Texas in 1972, only two countries of the Iberian world-Spain and Mexico-were represented.' At the time, it was apparent that the topic had attracted interest only as regarded the "mainstream" science countries of Western Europe, plus the United States. The Eurocentric bias of professional history of science was a fact. The sea change that subsequently occurred in the historiography of science makes 1972 appear something like the antediluvian era. Still, we would like to think that that meeting was prescient in looking beyond the mainstream science countries-as then perceived-in orde...
Plant organ abscission is a developmental process regulated by the environment, stress, pathogens and the physiological status of the plant. In particular, seed and fruit abscission play an important role in seed dispersion and plant reproductive success and are common domestication traits with important agronomic consequences for many crop species. Indeed, in natural populations, shedding of the seed or fruit at the correct time is essential for reproductive success, while for crop species the premature or lack of abscission may be either beneficial or detrimental to crop productivity. The use of model plants, in particular Arabidopsis and tomato, have led to major advances in our understan...
