In a linear model with “Sex”, “Julian date”, and “Year” (continuous variable), the year parameter estimate was highly significant (t = −7.6, p < 0.001), representing 13.8% reduction of the calf body mass during 1992–2018.
In a linear model with “Sex”, “Julian date”, and “Year” (continuous variable), the year parameter estimate was highly significant (t = −7.6, p < 0.001), representing 13.8% reduction of the calf body mass during 1992–2018.
The calf recruitment index (calf per adult female/subadult) tended towards a negative trend during 1990–2018 (t = −1.87, p = 0.072), with a 16.7% reduction based on model predictions.
