Analyzing branch growth is a key to understand survival and growth strategies of tree species because branch growth determines architecture, which, in turn, determines the amount of light captured by the foliage and carbon gain by the photosynthesis. In this study, we measured mass growth of first-order branches together with light intensity, branch initial size, and branch age to understand how branch growth is determined by these factors in four evergreen broad-leaved species growing under a forest canopy. We used hierarchical Bayesian approaches to fit a model that related branch growth and the factors considering nesting error structure. There were some quantitative differences in the parameter estimates. Therefore, patterns in branch growth differ among species.
