Short-term temporal changes in tree live biomass in a central amazonian forest, Brazil

We monitored seventy-two 1 ha permanent plots spread over 64 km2 of terra firme forest at Reserva Ducke (Manaus, Amazonas, Brazil) over 2-yr intervals to assess the effects of a soil and topographic gradient on the rate of change in the aboveground tree live biomass (AGLB). AGLB increased significan...
