I use species
distribution models (SDMs) to solve macroecological questions that are often related to studying
the impact of global change on species, their ranges, their traits, and to
biodiversity and communities. Much of my work has centered on improving and
conceptualizing the SDM metho- dology. I frequently also combine it with other approaches.
I use phylogenies and
phyloge- netic comparative methods to study the evolution of species, their
traits, and how they adapt to a changing environment and thus contribute to
assemble to com- munities and to form biodiversity at a range of scales. I mostly
work with plants, often trees, but some- times also with animals (birds, fish) as study
I use (and rarely contribute to develop) dynamic approaches to study the effects of demographic and physiology on species and ecosystem responses to global change. My primary interest is to find novel ways to study rege- neration, growth and mortality as important demographic processes to study global change effects.
I often use Geographical Informa- tion
Systems (GIS) and Remote Sensing (RS) tools to generate large
extent predictive layers useful for model building and ecological
analyses. The scaling of climate layers from coarse (global, regional climate
models) to a high spatial resolution (e.g. 100m, 1km) and to derive physiologically meaningful predictors are important elements.
