The data above were extracted from
Thomson Reuters's
Essential Science IndicatorsSM database. This database,
currently covering the period January 1998 thorough October 2008, surveys
only journal articles (original research reports and review articles)
indexed by Thomson Reuters. Articles are assigned to a category based on
the journals in which they were published and Thomson Reuters’s
journal-to-category field definition scheme. Both articles tabulated and
citation counts to those articles are for the period indicated. Here our
ranking of journals in ecology and environmental sciences is by citations
per paper to reveal weighted impact. Essential Science Indicators
lists journals ranked in the top 50% for a field over a given period, based
on total citations.
In ecology and environmental sciences, 168 journals are listed, meaning 336
journals in this field were surveyed. Of these 168 journals, 54 received
10,000 or more citations during the period. This ranking should be
recognized as distinctly different from Thomson Reuters’s impact
factor rankings, which are presented in the Journal Citation Reports issued
each year. The impact factor is calculated as citations in Year 3 to a
journal’s contents in Years 1 and 2, divided by the number of
so-called citable items (regular articles and reviews) in Years 1 and 2.
Thus, the above ranking reveals longer term impact (citations per paper).
The data for the multidisciplinary journals listed –
Science, Nature, and the Proceedings of the National
Academy of the USA – take into account only those articles that
have been classified by Thomson Reuters as ecology and environmental
sciences papers.
