Habitat fragmentation and reduction in the availability of suitable habitats are significant threats to ecosystems in particularly for freshwater ones. For instance, accessibility, availability, and quality of breeding sites of Atlantic salmon, Salmo salar, can be restricting in some rivers due to human activi- ties and dams. Such threats may affect distribution of potential breeders because after their up-river migration, salmon females distribute within available breeding sites. Spatial distribution of females determines the spatial distribution of breeder males. Dominant males try to monopolise several fe- males, whereas subordinate males adopt a sneaky behaviour. Access to females by males depends on the spatial distribution of females ...
