Impact of the global warming on the spatial distribution of fishery resources along the French coast : Observations and scenarios
This aims to study the impact of climate warming on the spatial distribution of fish in the North Atlantic, using the new habitat model called the Non-Parametric Probabilistic Ecological Niche Model (NPPEN). The model NPPEN is nonparametric and requires only presence data. It is based on concept of...
