Large-Scale Patterns of Turnover and Basal Area Change in Andean Forests

摘要: General patterns of forest dynamics and productivity in the Andes Mountains are poorly characterized. Here we present first large-scale study Andean using a set 63 permanent plots assembled over past two decades. In North-Central tree turnover (mortality recruitment) growth declined with increasing elevation decreasing temperature. addition, basal area increased Lower Montane Moist Forests but did not change Higher Humid Forests. However, at higher elevations lack net excess mortality recruitment suggests negative environmental impacts. North-Western Argentina, appear to be influenced by land use history addition variation. Taken together, our results indicate that combinations abiotic biotic factors vary across gradients important determinants Andes. More extensive longer-term monitoring analyses will necessary understand how demographic processes woody biomass responding changing conditions along through this century.
