Terrestrial, marine and freshwater ecosystems are undergoing an unprecedented period of change as a consequence of human activities. Among the foremost threats to biodiversity, climate and land use changes are redrawing the geographical distribution of species on Earth surface. There is an urgent need to understand how such changes will impact on the ecosystem functioning and services. The principle of conservation biogeography is to use the conceptual ideas and methodological approaches of biogeography to address such real world conservation issues.
The main objectives of conservation biogeography are to provide predictions about the changing state of biodiversity over time and to provide anticipative solutions to facilitate the response of biodiversity to future environmental changes. Global change impact modelling is one of the most burning issues and a dynamic research area in conservation biogeography.
The emphasis of my activities is on:
- Improving and applying ecological modelling approaches to predict global change related species distribution shifts in the future
- Including a variety of environmental variables from varying data sources (e.g. climate, land use, soil properties, biotic interactions) in ecological models to predict species distributions shifts under global change
