Fig. 8From: Are diurnal time-budgets and activity patterns density-dependent in the Shelduck (Tadorna tadorna) wintering in Algeria? An analysis across multiple temporal scalesRelationships between population size and diurnal activities of the Shelduck wintering in Sabkha Djendli (Northeastern Algeria). Size and grey-color intensity of the scattered points are set to values of activity time-budgets. The solid blue lines represent a linear regression with a Gaussian GLM fit and 95% confidence regions in light greyBack to article page
