GENERAL RESEARCH TOPICS

My research is mainly in Fish Community Ecology and Ecological Modelling.
In Fish Community Ecology, my research concerns the biodiversity and the spatial
distribution of fish according to the environmental characteristics and the response of fish
community to the human disturbances. The distribution of fish is considered according to the
scale of variation, varying from local to regional and global scales, in relationship with the
environmental variables.
In Ecological Modelling, I am mainly interested in the applications of Artificial Neural
Networks in Ecology, using supervised and un-supervised learning algorithms. However, I am
also familiar for the uses of classical modelling techniques, like classical statistic methods
(multiple linear regression, multi-variate analyses, ...) and modern statistical methods (CART,
GAM, PLS, ...).
One of my favorite papers is Application of neural network for nonlinear modeling in
ecology (Ecological Modelling 1996, 90: 39-52), which concerns a comparison of Artificial
Neural Networks and classical statistcs to model ecological data. My second favorite paper is
Energy availability and habitat heterogeneity predict global riverine fish diversity
(Nature 1998, 391 : 382-384), which applied the artificial neural networks to predict the
species richness of fish in the world. (See my Publications
in
http://sovan.lek.free.fr/slek/publi/PubliLek.htm
for a complete list of publications)
My research topics included:

Environmental Alteration, Native and Non-Native Fish Species


Impacts of Dams on Fish Assemblages

Biological Invasions in Freshwater Systems

Fish Community Spatial & Temporal Organisation in Temperate Lakes
