Species diversity varies greatly across the world’s ecosystems. One hectare of forest can have as few as one, or, in some tropical forests, as many as 300 tree species (Fig 1 b). Explaining the global diversity patterns is one of the greatest challenges of ecology - this is particularly pressing as global change and increasing disturbance events (Fig 1 c) are causing rapid losses in diversity. Forest diversity is hypothesised to determine how resilient these forests will be to changing environmental conditions, but the links between diversity and forest resilience are yet to be tested.
There is strong evidence that the velocity of life and death in forests are accelerating across the world, with increases in tree mortality and tree growth (forest dynamics). At the same time, the species composition of tree communities has been changing, favouring faster growing trees. This project will leverage big data on tree communities and ecological theory to develop a new understanding of how the dynamics of life and death, alongside species’ life history strategies, affect species diversity and forest resilience, at a global scale. This PhD project aims to investigate (1) the role of forest dynamics (i.e. growth, recruitment and mortality rates of trees) in determining species diversity; (2) how the life-history strategies of the species within a forest influence its diversity; (3) how diversity, forest dynamics and species composition influence forest resilience – i.e. the ability for a community to ‘bounce back’ after disturbance. By helping to answer such a fundamental question in Ecology, this project contributes to our understanding of the future trajectories of biodiversity.
