Calibrating individual tree biomass models for contrasting tropical species at an uneven-aged site in the native Atlantic Forest of Brazil: A direct comparison of alternative approaches, sample sizes, and sample selection methods

•Calibration of existing species-specific models are viable for abundant tropical species.•Inclusion of tree height enhanced calibration performance of species-specific models.•Use of woody specific gravity improved prediction accuracy across species and sites.•One to three randomly selected trees were sufficient for effective model calibration.
