The back-transformed least square mean annual citation rate and standard error for publications (N = 27,225) with one (N = 2,188), two (N = 5,523), three (N = 6,032), four (N = 4,949) and five or more (N = 8,533) authors in invasion science published between 1980 and 2020 and registered in Clarivate Analytics Web of Science Core Collections (see methods for screening criteria). Annual citation rate was calculated as the number of citations divided by the number of years since initial publication. Outliers for number of authors (N = 1; 642 authors) and number of citations (N = 8; > 1900 citations) were excluded.
