The Universal Individual-Based Model (UIBM)

Picture: Video 1: - This demo shows UIBM-screenshots. It starts with screenshots of the model start. Two more shots display the results of virtual experiments done with UIBM. They are followed by some shots of inspecting major component functions. The demo ends with shots of inspecting component structure.

UIBM - The Next Generation of Biodiversity Models

Basic UIBM Idea

(which makes UIBM a biodiversity model)
Once a template species is successfully constructed from databases and a Universal Individual-Based Model is developed along that way, more species can be easily constructed, since information in the databases is idential for all species.

Demo-Video 2

Click on the figure to watch the template species Arrhenatherum elatius grow in the virtual world. In the demo-video the ontogeny is followed from seedling to the time of first flowering.

Demo-Video 3

Click on the figure to watch a virtual vegetation survey plot with 1,000 Arrhenatherum elatius plants.
The 1,000 plants are contained in 100 databases. At an interval of milliseconds of simulatin time 10 plants are queried from a database, stepped and then committed again to the same database. At the end of the whole sequence shown in this video simulation time proceeds to the next time step (in this case: + 1 hr).
