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 data (…)

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 (…)
