Differences in growth patterns between co-occurring forest and savanna trees affect the forest-savanna boundary

FUNCTIONAL ECOLOGY, 23(4), 689–698.

author keywords: cerrado; ecosystem dynamics; forest-savanna boundaries; leaf phenology; photosynthesis; specific leaf area
TL;DR: Comparisons of patterns of leaf phenology, stem radial growth and branch growth of co-occurring savanna and forest trees in the Cerrado region of central Brazil suggest that forest trees that invade the savanna tend to present higher growth rates and larger and denser crowns, which enhance shading and could promote changes in equilibrium of forest–savanna boundaries.
