Algunos símbolos en el mito del origen del mundo en Oxkintok

Durante los seis años de trabajo de campo de la Misión Arqueológica de España en México, mientras se llevaba a cabo el Proyecto Oxkintok, de excavaciones y restauraciones en esa ciudad maya del noroeste de Yucatán, hubo una intensa relación con los habitantes del pueblo de Maxcanú. Un mito de origen recogido entonces es ahora analizado bajo la perspectiva del simbolismo de determinados elementos, y de su aprovechamiento para arrojar algo de luz sobre el pasado prehispánico del área.From 1985 until 1991 the team of the Misión Arqueológica de España en México was the guest of the small town of Maxcanú (Yucatán), while working in the maya ruins of Oxkintok. One mith colected in this time is here analised and argumented on the ground of literary simbolism

Tres himnos al sol

Todos los autores están de acuerdo en la importante significación de la heliolatría mesoamericana. Para entender cabalmente las expresiones arqueológicas de la religiosidad maya debemos indagar profundamente en los cultos solares del área, y una de las mejores maneras, a mi entender, de realizar tal cosa es a través del análisis de los textos escritos que han llegado hasta nosotros. Trataré aquí de desvelar el sentido de un himnoplegaria al sol característico, y lo compararé con otro procedente del altiplano mexicano. Finalmente, llevaré más allá la comparación, describiendo un himno del antiguo Egipto.All scholars are aware of the importance of the heliolatric cults in Mesoamerica. In this paper I analyse three hymns dedicated to the sun in the Maya area, in the Central Mexico Highlands and in the ancient Egypt. I think this is a very good path to a better understanding of those religious practices

The spatial scaling of food web structure across European biogeographical regions

The species–area relationship (SAR) is one of the most well-established scaling patterns in ecology. Its implications for understanding how communities change across spatial gradients are numerous, including the effects of habitat loss on biodiversity. However, ecological communities are not mere collections of species. They are the result of interactions between these species forming complex networks that tie them together. Should we aim to grasp the spatial scaling of biodiversity as a whole, it is fundamental to understand the changes in the structure of interaction networks with area. In spite of a few empirical and theoretical studies that address this challenge, we still do not know much about how network structure changes with area, or what are the main environmental drivers of these changes. Here, using the meta-network of potential interactions between all terrestrial vertebrates in Europe (1140 species and 67 201 feeding interactions), we analysed network–area relationships (NARs) that summarize how network properties scale with area. We do this across ten biogeographical regions, which differ in environmental characteristics. We found that the spatial scaling of network complexity strongly varied across biogeographical regions. However, once the variation in SARs was accounted for, differences in the shape of NARs vanished. On the other hand, the proportion of species across trophic levels remained remarkably constant across biogeographical regions and spatial scales, despite the great variation in species richness. Spatial variation in mean annual temperature and habitat clustering were the main environmental determinants of the shape of both SARs and NARs across Europe. Our results suggest new avenues in the exploration of the effects of environmental factors on the spatial scaling of biodiversity. We argue that NARs can provide new insights to analyse and understand ecological communities
