Curriculum Vitae:

Marcos Longo

Tropical forests are the most biodiverse terrestrial ecosystem and contain a large fraction of land carbon, yet the role of tropical forests in the global carbon cycle is still uncertain. My main research interest is to understand how changes in climate and land cover and land use in tropical regions affect the carbon stocks, structure and functioning of tropical forests. My current research focus on integrating airborne lidar, satellite data (e.g. Landsat, MODIS, ECOSTRESS), and the Ecosystem Demography Model (ED-2) to quantify and predict the impact of human disturbances - fires, selective logging, fragmentation - on the productivity, evapotranspiration, and flammability of degraded forests. I am also interesting in understanding how extreme events such as droughts affect the dynamics of tropical forests.
