Research at the University of Exeter examines how measurements of charcoal reflectance can be used to understand fire regimes and carbon dynamics in tropical forests in South America.
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.
The public selection process is now open for assessing and selecting candidates for admission to the Masters and PhD programme in the Tropical Forests Science Programme at the National Institute of Amazonian Research (INPA) with research projects matching themes of the Post-graduate programme in Tropical Forest Science (PPG-CFT).
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.
The fire regime of tropical forests is changing rapidly, with implications for forest cover, carbon storage, species composition, biodiversity, function, and climate. These changes are having a range of impacts over varying spatiotemporal scales and are explored in a journal special issue on the Transformation of Tropical Forests through Fire.
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 […]
New research in Geography at the University of Exeter is developing a charcoal reflectance methodology into a novel metric with which to assess fire severity and the amount of energy that has been delivered across burned areas in the UK, USA and Brazilian Amazon.
We are seeking qualified and motivated candidates to pursue a PhD in forest degradation and ecosystem services in tropical montane forests.
Our recent research highlights the negative effects of fire on the forest carbon sink in seasonally flooded forests in southern Amazonia, an area rich in diversity at the forest-savanna transition, including permanent forest plots from the Parque Estadual Araguaia.
