Between 2003 and 2007, Thomson Reuters indexed 76,440 papers that listed at least one author address in Brazil. Of those papers, the highest percentage appeared in journals categorized under the heading of agricultural sciences, followed by plant & animal sciences and microbiology. As the right-hand column indicates, Brazil has yet to attain the world impact average in any of the fields shown, although its score in mathematics for the five-year period was at 89% of the world mark (or just 11% below: 1.28 cites per paper for Brazil versus the world average of 1.44 citations). The nation's relative impact was also comparatively strong in physics, ecology/environmental, and geosciences.
