The data above were extracted from
Clarivate'sEssential
Science IndicatorsSM database. This database, currently
covering the period January 1997 to December 2007, 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 Clarivate’s journal-to-category field
definition scheme. Both articles tabulated and citation counts to those
articles are for the period indicated. Naturally, scientists publishing
large numbers of papers have a greater likelihood of collecting more
citations than scientists publishing fewer papers. This ranking is by total
citations. For articles with multiple authors, each author receives full,
not fractional, citation credit. Another ranking could be based on
citations per paper, which reveals weighted impact.
A survey of the research interests of these scientists reveals some major
themes: biodiversity, population dynamics, ecosystem functioning and the
impact of man, global climate change, conservation biology, and
ecotoxicology including the environmental effects of organic contaminants
(Giesy, Jones, and Kannan). Essential Science Indicators lists authors
ranked in the top 1% for a field over a given period, based on total
citations. For the current version, 2,800 authors are listed in the field
of environment/ecology, meaning that a total of approximately 280,000
authors’ records were reviewed to obtain these results
