Inclusion of water temperature in a fuzzy logic Atlantic salmon (Salmo salar) parr habitat model.
As water temperature is projected to increase in the next decades and its rise is clearly identified as a threat for cold water fish species, it is necessary to adapt and optimize the tools allowing to assess the quantity and quality of habitats with the inclusion of temperature. In this paper, a fu...
