Dear all, Isi has published the 2013 impact factor, and  IF of some journals were lowed and sometimes banned especially because of self citation. Among the journals devoted to acarology and systematics SYSTEMATIC AND APPLIED ACAROLOGY got its first impact factor of 1.115 , INTERNATIONAL JOURNAL OF ACAROLOGY, is with impact factor 0.691 ACAROLOGIA is not referenced. Can somebody explains the differences noted with the indexes published by SJR (http://www.scimagojr.com/index.php)? (see the attached files ) .
