Biomass and primary-production of herbaceous plant communities in the Amazon floodplain

The increase in biomass of different aquatic and terrestrial herbaceous plant communities was measured during various growth periods in the Amazon floodplain near Manaus. Maximum biomass varied from 4-11.2 t ha-1 dry weight in mixed annual terrestrial communities to 6-23 t ha-1 in aquatic annual spe...
