Productividad interanual e interestacional de la biomasa aérea en la Chiquitanía transicional a la Amazonía (Guarayos, Bolivia) Interseasonal and interannual productivity of above - ground biomass in a transition from Chiquitano to the Amazon (Guarayos, Bolivia)

Recent studies suggest that climate change will intensify seasonality resulting in prolonged droughts that may drastically reduce carbon storage in Amazonian forests. In order to determine drought impacts on a forest biomass at a local scale, this study allometric equations to estimate changes in tree and forest biomass based on wood density, tree height and monthly diameter growth of trees with DBH ≥ 10 cm in two plots of 1 ha (100 x 100 m) in a humid forest (BH) and a dry forest (BS) in Kenya, Guarayos (Santa Cruz, Bolivia). These estimates were used to compare biomass productivity (PBA) of a wet year (2009) and a dry one (2010). We also compared PBA among seasons (wet, semi-dry, dry, semi-wet seasons). The annual PBA was significantly higher
