The data above were extracted from
Thomson Reuters's
Essential
Science IndicatorsSM database. This database, currently
covering the period January 1998 to February 2008, surveys only journal
articles (original research reports and review articles) indexed by Thomson
Scientific. Articles are assigned to a category based on the journals in
which they were published and Thomson Scientific’s
journal-to-category field definition scheme. Both articles tabulated and
citation counts to those articles are for the period indicated. Naturally,
institutions publishing large numbers of papers have a greater likelihood
of collecting more citations than scientists publishing fewer papers. This
ranking is by citations per paper (impact), among those institutions that
have collected 10,000 or more citations in environment and ecology
journals. For papers with multiple institutional addresses, each
institution receives full, not fractional, citation credit.
Essential Science Indicators lists institutions ranked in the top
1% for a field over a given period, based on total citations. For the
current version, 461 institutions are listed in the field of environment
and ecology, meaning that a total of 46,100 institutions were reviewed to
obtain these results. Of the 461, 61 institutions collected 10,000 or more
citations in environment and ecology. US institutions take the top five
places in this ranking, and a total of 13 in this list of the top 20 by
citations per paper. UK institutions rank 6th, 7th, 8th, and 14th. Germany,
Sweden, and Switzerland are represented by one institution each. Of course,
the Max Planck Society represents several locations. Visit
