Competition influences tree growth, but not mortality, in Amazonia and tropical Africa forests

Posted Posted in Africa, Amazonia, Carbon sequestration, Climate change, Drought, Forest dynamics, Forest structure, Tree growth, Tree mortality

Competition among trees is an important driver of community structure and dynamics in tropical forests. Neighboring trees may impact an individual tree’s growth rate and probability of mortality, but large-scale geographic and environmental variation in these competitive effects has yet to be evaluated across the tropical forest biome.

Fire effects on understory forest regeneration in southern Amazonia

There has been a large increase in deforestation and wildfire in Amazonia over recent years. Fire in tropical forests increases tree mortality, degrades forest structure, and reduces carbon stocks (Figure 1). Remote sensing now permits a rapid and accurate assessment of the location and extent of fires. On the ground and in forests, however, there […]
