Table 1. Description of the Brazil nut tree recruitment pulses at Purupuru Lake, Central Amazonia.

Period of establishment based on our combined estimate of tree ages, mean diameter of trees (± standard deviation), and mean age in each pulse based on the Gaussian finite mixture model (± bootstrap confidence interval).

Recruitment Pulse	Period of establishment	Nº of trees	Average diameter (cm)	Average age (yr)
1st Pulse	1604–1818	41	132.7 (±29.3)	303 (289–314)
2nd Pulse	1840–1989	43	64.7 (±33.2)	119 (106–134)
