Partitioning of the variance in the number of prey encounter events (nPEE) explained by each of the GLMM (on the y-axis) at the scale of dives (A) and days (B). The proportion of the variance explained by the predictors via the fixed slope variance (\({{R}}_{{{F}}}^{2}\); grey bar), by the individual-specific means via the random intercept variance (\({{R}}_{{{I}}}^{2}\); yellow bar), and by the predictors via the random slope variance/covariance (\({{R}}_{{{S}}}^{2}\); blue bar). Dive metrics are calculated from the low-resolution dive profiles, i.e., simplified to five segments using the broken stick method similar to data transmitted by CTD-SRDL loggers
