A new approach to landscape ecology involves the application of the eco-field hypothesis and the General Theory of Resources. In this study, we describe the putative eco-field of bark beetles as a spatial configuration with a specific meaning-carrier for every organism-resource interaction. Bark beetles are insects with key roles in matter and energy cycles in coniferous forests, which cause significant changes to forestry landscapes when outbreaks occur. Bark beetles are guided towards host trees by the recognition of semiotic signals using (...) a specific eco-field. These signals mainly comprise a group of scents, which are called the odourtope. Their interactions with other organisms occur by sharing relevant information from the eco-field networks in the forest ecosystem. The eco-field networks modulate the expansion of the realized semiotic niche of the bark beetle towards the potential semiotic niche. Moreover, the niche construction process can be initiated by interchanging signals among species living in the same place, where these signals allow the exploitation of the required resources. If different organisms are interdependent on signals in eco-field networks, then this process may result in the establishment of mutualistic relationships. This is an example of how evolutionary processes are initiated by the recognition of signals in a network of eco-fields. (shrink)

The processes of globalization, embraced with such eagerness in the 1990s, started being reviewed a decade later, having revealed a vicious underside. Behind the diverse masks of globalization hide murderous identities that promise different types of violence. During Brexit, the referendum in June 2016 that was to decide whether the United Kingdom left the European Union or stayed in it, Britain rejected what the EU represents—a common identity—to pursue a road on its own—a separate identity.1 Significantly, one of the elements (...) that analysts regarded as central to Brexit was immigration. According to a recent book by Nidesh Lawtoo, immigration is one of the main rhetorical tropes of the new political... (shrink)

La presencia de préstamos léxicos en una lengua es un indicio de la introducción de una palabra foránea y una nueva realidad. Aquí discutiré cómo la presencia de préstamos léxicos en las lenguas es un indicio de la pluralidad del mundo real. Para esto, tomaré la tesis expuesta por Lewis sobre la pluralidad de mundos y presentaré ejemplos del muisca y del español1, como una prueba de que el mundo, como un único lugar donde todo está incluido, conlleva la pluralidad (...) del mundo real, debido a que hay otro que suele ser desconocido y, en consecuencia, no posible dentro de sus mundos posibles.
