Uncovering operational interactions in genetic networks : application to an apoptosis network
Biological networks of large dimensions, with their diagram of interactions, are often well represented by a Boolean model with a family of logical rules. An advantage of Boolean and discrete modelling is the possibility of fully characterizing all qualitative dynamical trajectories of a particular network, based simply on the structure of links and interactions between nodes. A biological network (...)

Niche dynamics of sympatric herbivores
The distributions of the Trans-Himalayan large herbivores are fragmented, engendering a spatial heterogeneity in their species-richness. We capitalised on this natural-experiment situation to understand the niche dynamics of herbivores in relation to the number of sympatric species. We used the blue sheep Pseudois nayaur, a relatively widely distributed mountain ungulate, as a model species to address the issue. We selected three discrete valleys in (...)

Creating dynamic maps of biodiversity : examples in R + Google Earth
The seminar will focus on application of open source tools for
analysis of biodiversity data. The focus is put on R statistical
computing environment and its various Environometrics and Spatial
packages. There are three main opportunities for using R : (1) vitality
and high speed of development of R, (2) academic openness of developers
and their willingness to collaborate, and (3) increasing sympathy for
spatial (...)
