How important are the mountains for understanding forest patterns along elevation gradients. In this talk, I will describe a tropical forest laid upon an elevation gradient in a geomorphic disequilibrium to understand whether spatial patterns of slope and slope-dependent processes may cause nonlinear patterns of vegetation. The focus of the study is the upper Icacos River basin in the Luquillo Mountains, Puerto Rico ? a landscape currently adjusting through erosion to a 4-My-ago uplift event. These findings indicate that forest patterns on this tropical elevation gradient are strongly influenced by both climate and erosional controls driven by tectonics.
