Descriptive statistics of the results of the behaviour of males (ex-ante) and the behavioural responses of males exposed (ex-post) to the treatment waters. Nstone: handling the air-stone as frequency (n), Tstone: time (s) of handling the air-stone as time, AntFlic: time (s) of antennal flicking, CrayMov: time (s) of crayfish moving. Sample size (N), means, standard deviation (SD), and ranges (minimum and maximum) are shown.
