Spatial learning based on visual landmarks in the freshwaterblenny Salaria fluviatilis (Asso, 1801)

The use and learning of visual landmarks seem to be strongly influenced by ecological demands and vary according to habitat, sex and, presumably, dominance status. In blennies, sexes differ in their home-range extension and this could predispose them to use different mechanisms to navigate. The main...
