Landscapes are spatially heterogeneous geographic areas composed of interacting vegetation patches or ecosystems, ranging from natural systems to human-modified environments. Such a template influences the spatial patterns of species distribution and key ecological processes.
Spatial ecology is the confluence point between ecology and geography. This discipline focuses on identifying spatial patterns in the environment and on examining the influence of such patterns on the geographic distribution of ecological events like the spatial distribution of organisms. Landscape ecology makes use of methodological approaches developed in spatial ecology. One of the core research areas of landscape ecology is to relate landscape patterns across a variety of scales to key ecological processes and mechanisms (e.g. species dispersal, species interactions, habitat selection) across a variety of scales.
The emphasis of my activities is on:
- Using spatial modelling techniques to improve the sampling of conservation-interest species
- Applying spatial modelling techniques to long-term biodiversity monitoring data to document changes in species distribution
- Optimizing long-term biodiversity monitoring projects for spatial modelling applications
- Understanding the habitat selection patterns and processes of organisms in human-modified landscapes
