These are projects I am currently working on:
The following projects have recently been finished:Interests
I am specifically interested in vegetation ecology, vegetation dynamics,
and plant species diversity at various spatial and temporal scales. In
the past few years, my research has focused on modeling biophysical constraints
of species and community distribution along spatial (real) and theoretical
gradients, and on modeling species competitive dynamics on large spatial
scales. This research required the interaction of plant ecophysiology,
ecological theory, biophysical ecology and involved mainly GIS-analyses,
programming and statistics. Additionally, I have a strong sympathy for
field floristics, species diversity theories, and ecological theories in
general.
