Harison is based at the University of Antananarivo (Madagascar) and his thesis is entitled “Landscape ecology of tropical forest trees in Madagascar”. In the context of extensive land cover change and fragmentation as well as local extinctions of frugivores, it is important to understand how tree species are responding, in particular whether seed dispersal and recruitment can still occur for certain species in fragmented landscapes. In this project, a network of forest plots have been established in two contrasting forest types: Mariarano tropical dry forest in the west and Ankeniheny-Zahamena tropical moist forest in eastern Madagascar. Satellite remote sensing has been used to characterise land cover change dynamics. Tree species traits have been used to test for sensitivity of species to landscape configuration. Finally drones are being used to test new methods for monitoring forest degradation.
