Branch diameter profile of five sample trees: (a) and (b) stand Sault, tree 5; (c) stand B24, tree 1; (d) stand B34, tree 4; (e) stand Citou, tree 4; (f) stand Lub, tree 2. Horizontal axes: 0 = apex; 100 = tree base. Dots: highest branch observed in every annual shoot. Circles: other branches observed (in one shoot every three shoots). The vertical dotted line is for the CR value. (a) solid line: individual model. (b–f) line with small dashes: overall model with fixed effects only; line with large dashes: overall model with fixed effect and random tree effect; solid line: overall model with fixed effect and random tree and annual shoot effects
