Dead Sea Asphalt from the Excavations in Tel Arad and small Tel Malhata
No full textAsphalt was found in the excavations of Tel Arad and Small Tel Malhata in the Northern Negev, Israel, in levels dated as Early Bronze I and II. Detailed chemical analysis indicates that this material, used as a glue on various utensils, resembles natural occurrences of asphalt blocks which are occasionally found floating on the Dead Sea. Although the historical records of 2000 years ago indicate that Dead Sea asphalt has been an important trade item of the region, this is the first evidence that Dead Sea material can be found outside its source area. It also indicates that the export of Dead Sea asphalt had begun at least 3000 years before the earliest historical record by Diodorus of Sicily (ca. 50 A.D.).Du bitume a été trouvé au cours de fouilles de Tell Arad et du petit Tell Malhata dans le nord du Néguev, en Israël, dans les niveaux datés du Bronze Ancien I et II. L'analyse chimique indique que ce bitume, utilisé sur des objets divers, est de même nature que les blocs de bitume que l'on trouve parfois flottant à la surface de la Mer Morte. Les textes anciens mentionnent que le bitume de la Mer Morte était une denrée d'exportation importante de la région il y a deux mille ans; le bitume de Tell Arad et du petit Tell Malhata est le premier témoin de ce matériau en dehors de son lieu d'origine. Il indique aussi que le commerce du bitume de la Mer Morte a commencé au moins 3000 ans avant l'apparition de la première mention historique faite par Diodore de Sicile vers l'an 50 de notre ère.Nissenbaum Arie, Serban Andrei, Amiran Ruth, Ilan Ornit.

Speciation of chilean Rhinocryptidae (Avian) based on their behaviour
No full textThe current classification of the chilean representatives of the passerine family Rhinocryptidae includes eight species. Three of them contain subspecies that don't exhibit clear differences. Moreover, differences among two lineages of _Scytalopus_ genera and two species of _Pteroptochos_ are cryptic. We propose a new methodology based on ecological and behavioural patterns in order to understand the concept of speciation in this group of birds. According to our results, we postulate that there is not a cut criteria to establish differences among three sister lineages of current classification. This way the methodology developed by us does not allow to establish divergence for a given common ancestor. Our methodology allows to establish comparison among previously determined phylogenetic lineages. Our results show how when integrating behaviour and ecological terms as biological traits next to morphological characters of the plumage, it allows us to conclude that there is decrease of the distances among sister lineages in the cluster tree
