Influence of adult presence on juvenile activity: (a) examples of tracks (i.e. individual movements) of the juveniles in the experimental design. The left and right enclosures correspond to the single (i.e. no adult) and the exposed (i.e. adult visible) treatments, respectively. Each enclosure consisted of two arenas separated by transparent glass. The coloured paths indicate the distance travelled by individuals during 1 h recording (red and yellow: juveniles; green: adult); (b) distance travelled (mean ± S.E.) in the experimental enclosure during 1 h by juveniles, without and with the presence of an adult.

Effect of the time of day on number of encountered horned frogs, according to life-stage: (a) adults (dark brown); (b) juveniles (light brown).
Surveys between 7:00–19:00 considered diurnal, and those between 19:00–7:00 nocturnal. Bars: mean; whiskers: S.E.
