A new study by Pontes-Lopes et al. 2021 examining the impacts of the record-breaking drought and fires caused by the 2015/2016 El Niño has found that even the wet forests of central Amazonia, forests considered relatively fire-resistant, were affected by fire.

Two complementary PhD studentships have been funded thanks to donations from long-term University of Exeter supporters, the A. G. Leventis Foundation. Both will be based within the Global Systems Institute and focus on tropical forest protection and restoration, specifically understanding carbon storage within degraded and recovering forest ecosystems.

Fire is an important cause of disturbance in terrestrial ecosystems and can has a major impact on biodiversity. We evaluated the effect of fire regime on species richness and tree basal area in southern Amazon forest using Landsat and PALSAR data.

Scientists unravel how and why Amazon trees die

A huge new study has unravelled what factors control tree mortality rates in Amazon forests and helps to explain why tree mortality is increasing across the Amazon basin. The capacity of the Amazon forest to store carbon in a changing climate will ultimately be determined by how fast trees die. The new analysis found that the […]

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.
