Table 1
Final models to assess the relationships between independent (sex; diel period; number of raw values) and dependent (vertical movement in m h−1, n = 12,688; and horizontal movement in m s−1; n = 13,106) variables. Hour (hour of the day), Day (each day of the study period), and Individual fish (unique IDs of the fish) were included, but varied, as random variables between the models. Bolded p-values indicate a significant result (p < 0.05).
