Innovation by ancient farmers to improve soil fertility continue to have an impact on the biodiversity of the Amazon, a major new study shows.
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.
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 are significant challenges to estimating the actual effects of fire on forests across a region the size of Europe.
Fire is an important disturbance factor on the land surface, and effects carbon, nitrogen and water cycles, and it is therefore important to be able to represent this process in models. (more…)
We are seeking qualified and motivated candidates to pursue a PhD studying how lighting affects tree mortality, carbon dynamics, and forest composition in tropical forests.
