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).

The data above were extracted from Thomson Scientific’s Essential Science Indicators 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 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, 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. 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.

Recent controversy over the future directions of both Stanford and Melbourne university presses have raised questions about the role of in-house publishing arms in a world of commercialisation, impact agendas, alternative facts – and ever-diminishing monograph sales. Anna McKie reports
