title: Erratum.
abstract: In Roger Lewin's Research News article "Recount on Amazon trees" (5 Feb., p. 563), two errors occurred. At the end of the third paragraph, the quote from Alwyn Gentry should have ended, ". . . with 63% of species represented by single individuals and only 15% of species represented by more than two individuals." The last word of the article should have been "importance."
