Producción científica venezolana: apuntes sobre su pérdida de liderazgo en la región latinoamericana.

The evolution in scientific production and collaboration of Venezuela is discussed, identified as a country that has been characterized by the loss of leadership in recent years. The universe of analysis is composed by 1.117 Ibero American open access journals indexed by the database redalyc.org with over 250.000 articles in a period of 10 years (2005-2014). The fall of Venezuelan science is seen from mainstream science databases (in Scopus, through SJR, it showed 1.857 papers in 2005 that represented 3,4% of the region. In 2014 it had 1.592 papers, that accounted for 1,44% of the region. That is, it had a drop of -14,27%) and from Redalyc (which it had 875 articles in 2005 that they accounted for 5,5% of the region; in 2014 had 791 articles, which represented 3.0% of the region. So, it fell -9,6%); this database allows further appreciation about a high rate of concentration in the scientific and editorial production of Venezuela, as well as an endogenous behavior in terms of production and collaboration.
