                         composition and biomass content of tropical forests, which are not 
                         adapted to this disturbance. To assess the impact of understorey 
                         fires on above-ground biomass, this study was conducted in the 
                         northern Brazilian Amazon (Roraima state), where uncontrolled 
                         forest fires are recurrent. Fifty plots (0.25 ha each) distributed 
                         across five fire disturbance classes were inventoried. Losses in 
                         biomass stocks were significant (\−57% and \−63%) 
                         for forests that suffered from recurrent fires and progressively 
                         occurred until some point between 3 and 7 y after the last fire, 
                         as deduced from previous studies. Twelve years after a fire event, 
                         biomass stocks were reconstituted, although differences in the 
                         floristic composition were associated with greater fire severity, 
                         particularly driven by the dominance of the Cecropia spp. In 
                         thrice-burned forests, live biomass reached levels of secondary 
                         forests of the same region. For large trees (> 50 cm dbh), the 
                         reduction (\−54%) in biomass was significant in 
                         thrice-burned areas. These findings highlight the threat that 
                         fires represent for tropical rain forests and emphasise the need 
                         for long-term surveys in order to distinguish between the effects 
                         of fire severity, fire frequency and time-since-fire artefact.",
