Table 2 (a) The 8 species that changed significantly in abundance in the 30 quadrats of group 4 (the swamp) from T1 (1985) to T2 (2015). (b) Changes in abundances of these 8 species in 500 quadrats of group 1 during the same time interval. A taxonomic data table archived in Condit et al. (2017a) includes the family names and taxonomic authorities for all 455 species of the BCI data base
