Long time ago I built some dynamic models of bryophyte metapopulation dynamics (see publications ol1, ol2, ol3) in order to learn under what conditions a species can survive in a dynamically changing substrate mosaic.

Currently I am involved in a FW5 project TRANSPLANT (with Petr Dostál, Zuzana Münzbergová, Tomáš Koubek, Martin Křivánek) coordinated by Jan van Groenendael (Nijmegen University) that studies survival of grassland species in the fragmented European landscape.

Our group has been working in the following areas:

• tracking changes in demography and allocation due to management changes: do plants allocate more into dispersal structures (in order to escape) if habitat changes? This is mainly done by Petr Dostal.
  
  
• using dynamical models to understand and predict species persistence in fragmented landscapes. We collaborate particularly with the Swedish group (Sara Cousins, Johan Ehrlen, Ove Eriksson, Mikael Milden). This is the work of Zuzana and myself. More information is available in our talk given at the POP2003 meeting in Copenhagen
  
  
• we developed a technique to identify available, but unoccupied habitats using phytosociology data. More details here.
