Manejo integrado de florestas úmidas neotropicais por indústrias e comunidades: aplicando resultados de pesquisa, envolvendo atores e definindo políticas públicas. Belém: Embrapa-Amazonia Oriental: IUFROc2002  ap. 114-123.cil.  aData on recruitment and mortality are reported for trees ~ 5 cm dbh from 257 species at the Tapajós National Forest over an eight-year period after selective logging and in a nearby unlogged control area. Recruitment increased with time after logging while mortality was very high immediately after logging due to felled and damaged trees but slowed down by year 5 after logging. In the unlogged forest, recruitment and mortality were nearly equal during the period. Both recruitment and mortality rates were higher for light-demanding species than for shade-tolerants in the logged area over the study period, but in the undisturbed forest this situation was reversed. The effect of logging on dynamics of commercial species was positive, insofar as their mortality represented less than 15% of their recruitment. In the undisturbed forest, mortality and recruitment of commercial species were in equilibrium.  aExploração Florestal  aDinâmica de Floresta  aFloresta amazônica  aFloresta Nacional do Tapajós  aMortalidade de árvore  aRecrutamento de árvore
