FYI: ESA journals and Ecology Letters, in contrast to Science, Nature, PNAS, and PLoS ONE, will not publish papers previously posted to a “citable public archive outside the author’s home institution”, such as arXiv. See Jabberwocky Ecology for details.
ESA says they will be discussing their policy on this at the ESA meeting. No word on if Ecology Letters also plans to revisit their policy. (UPDATE #2: ESA policy has changed; they now allow preprints).
UPDATE: Apparently the staff writers for Nature have been following this discussion! From an article in this week’s (Aug. 2) issue, on how population geneticists are starting to use arXiv:
Some biology journals, such as those published by the Ecological Society of America in Washington DC, for example, expressly prohibit pre-publication in citable public archives.
That choice of example can hardly be a coincidence…
