confrontation and / or dependence, in the sense of scavenging ”, explains Ruth Blasco. The experimental series, which involve both large carnivores, such as the brown bear, and small carnivores, for example the fox or the badger, have been developed mainly in the Lleida Pyrenees, especially in the Parc Natural de l’Alt Pirineu, where there is no human conditioner that can alter the behavior of animals. “This circumstance is vital when extrapolating the experimental data, since the studies that have been carried out with carnivores in captivity or semi-freedom could run the risk of reflecting alterations in their behavior that would leave a different taphonomic stamp, and therefore , would lead to inadequate archaeological interpretations ”comments Ruth Blasco. Neotaphonomy The experimental approach arose in

2010 to respond to the occupational Bolivia Email Lists complexity of some Pleistocene sites, such as the Cova del Toll, in Moià (Barcelona), where one of the main species represented is the cave bear (Ursus spelaeus) . The first experimental results were published in the journal PLOS ONE in 2014. This Neotaphonomy project has the permission, supervision and collaboration of the Brown Bear Monitoring teams, the Alt Pirineu Natural Park, and the Department of Agriculture, Branch, Fisheries and Food of the Generalitat de Catalunya. In the same way, the experimental line is part of the research project “Sharing space: the interaction between hominids and carnivorSince Human Immunodeficiency Virus type 1 (HIV-1) was discovered in the early 1980s, the epidemic in the western world has been dominated by subtype B of this virus,

which traveled from Africa to the US via Haiti. . However, the pattern of subsequent spread remains poorly understood. Now, for the first time, an international team of scientists from the European Society for Translational Antiviral Research (ESAR) has mapped the spread routes of the virus around the world after it reached the US in the early 1970s. The study , which is published this Wednesday, June 15 in the Journal of Molecular Epidemiology and Evolutionary Genetics of Infectious Diseases, suggests that the expansion of HIV-1 subtype B reflects the geopolitical events of the second half of the 20th century, HIV is one of the fastest evolving human pathogens, which has now made it possible to study its movements over the years. Researchers have analyzed almost 9,000 genomes of HIV-1 subtype B strains from 78 countries,
