Table 4. Mean (range) values of each behavioural variable and results of the Friedman test (df= 3) for the experiment of Scelarcis perspicillata of the limestone quarry of Pedreres de S’Hostal (Menorca, Spain) with the four scent treatments (Macroprotodon mauritanicus, Rhinechis scalaris, Natrix maura, and an odourless control).
Only the behavioural variables that were displayed by lizards during the experiments are included in the table.
