Abstract
The distribution of submerged macrophytes in the littoral zone of Lake Geneva (Switzerland) was modeled from
bathymetry, wave exposure, current strength, water quality, soil type and harvesting practice. Generalized Additive
Models (GAM) were used to identify the responses of three Potamogeton species and Chara sp. to these
environmental parameters. The maps of original data and the spatial predictions were processed in a Geographic
Information System (GIS) database. The effect of the selected environmental variables on plant distribution is
discussed in relation to species adaptive strategies. GIS and GAM appear as powerful tools to proceed from
the description of species response curves to environmental gradients toward the spatial predictions of species
distribution under changing environmental conditions.
