In February 2009, Thomson Reuters added official Five-Year Impact Factors, Eigenfactors and Article Influence Scores to the 2007 JCR. An explanation of these new metrics can be found at http://science.thomsonreuters.com/press/2009/8499916/ There is still a far from complete understanding of the complex ecosystems in the Neotropics, although they have been studied since the first expeditions of the old world naturalists Marcgrave, Humboldt, Spix, Darwin, Bates and Müller. The aims and scope of the Journal are, besides taxonomic and zoogeographic surveys, analyses of animal communities and their relationship with biotic and abiotic environmental conditions. This includes the fauna of both terrestrial and fresh water ecosystems in the Neotropics. Contributions that represent original research and mini-reviews are welcome.
