Tropical landscapes are rapidly shifting from continuous tracts of undisturbed forest to complex landscape mosaics, and secondary forests comprise increasing proportions of these dynamic landscapes. Tropical landscapes will continue to change over the coming decades and research needs to keep pace with these shifts in land use so that we fully understand the value of emerging tropical landscapes for species conservation and ecosystem processes. I am interested in how tropical forest communities recover after disturbance, the interactions between the regeneration of forest plant communities and the recovery of key ecosystem processes, and how we can maintain viable populations of forest species in human-modified tropical landscapes. My principal research projects and collaborations are listed below:
Barro Colorado Nature Monument chronosequence study, Panama: Exploring long-term trends in species diversity and ecosystem function in secondary forest succession.
2ndFOR Network: A network of >45 secondary forest sites spanning the Neotropics, enabling us to make regional scale estimates about forest recovery.
Conservation potential of selectively-logged forest, Malaysia: Investigating the long-term sustainability of production forests in Danum Valley Conservation Area and surrounding forests, Sabah, Malaysia.
The environmental impacts of mega-dams in Amazonia, Brazil: This UK-Brazil partnership investigates the persistence of multiple taxa on islands in the Balbina dam reservoir in central Amazonia.
Balancing species conservation and agricultural productivity in tropical landscapes, Panama: This project aims identify how tree and bird community composition, seed dispersal and recruitment vary across gradients of forest cover and disturbance.
