CLIMEX predicts the effect of climate change on species distribution, using simulation and modeling techniques. CLIMEX attempts to mimic the biological mechanisms that limit species' geographical distribution and determine their seasonal phenology and relative abundance.

DYMEX is a modular modelling package that allows the user to develop and run deterministic population models of biological organisms rapidly. These population models are structured around species' lifecycles, which in turn consist of the growth stages that individuals pass through during their life.
