Size-dependent leaf area ratio in plant twigs: implication for leaf size opti…

Background and Aims Although many hypotheses have been proposed to explain variation in leaf size, the mechanism underlying the variation remains not fully understood. To help understand leaf size variation, the cost/benefit of twig size was analysed, since, according to Corner’s rule, twig size is positively correlated with the size of appendages the twig bears. Methods An extensive survey…
