Urs G. Kormann



I am a Postdoc with Matt Betts at Oregon State University. I seek to understand the dynamics of biotic communities, interactions networks and ecosystem functions in our rapidly changing world.  I explore ways to implement this knowledge for biodiversity conservation in human-modified systems. I am particularly interested in synergistic effects of global change drivers (e.g. habitat loss, land use intensification,  climate change) in space and time.  Broadly speaking,  my interests encompass (i) why organisms are where they are, (ii) how and why species interact(or not),  (iii) what ecosystem functions they provide (or not) and (iv) movement ecology. I like to tackle research questions from different angles, that is,  by combining experimental, observational, genetic and statistical modelling approaches. I have been working in tropical and temperate systems on a broad range of taxa, sometimes with large community datasets, sometimes single-species data, but with a certain taxonomic bias towards birds, insects and plants. Currently I am involved in two projects; effects ofintensive forest management on biodiversity, ecosystem functioning and pollinator-plant interaction webs in North America , and landscape effects on plant-animal interactions in Southern Costa Rica. I have an active interest in statistics, particularly in hierarchical modelling and statistical techniques to assess community shifts in space and time.
