Abstract:
... Predicted increases in the frequency and intensity of droughts across the temperate biome have highlighted the need to examine the extent to which forests may differ in their sensitivity to water stress. At present, a rich body of literature exists on how leaf- and stem-level physiology influence tree drought responses; however, less is known regarding the dynamic interactions that occur belowgrou ...

Abstract:
... The growth structure of Eucalyptus plantations is the result of site environment, genetic material, and different types of interaction between neighboring plants. It is well known that sites that are more homogeneous result in greater forest productivity. However, additional factors inherent in the micro-environment or the quality of cuttings can lead to heterogeneous clonal biomass at the end of ...

Abstract:
... High descending winds generated by convective storms are a frequent and a major source of tree mortality disturbance events in the Amazon, affecting forest structure and diversity across a variety of scales, and more frequently observed in western and central portions of the basin. Soil texture in the Central Amazon also varies significantly with elevation along a topographic gradient, with decrea ...

Abstract:
... Seasonal meteorological variability within and among years has significant impact on forest productivity, thus understanding its detailed effects on tree growth contributes to the knowledge of the processes controlling forest productivity. This study used high frequency measurements of dendrometer bands (every 2–4weeks over 1–2years) to assess tree growth of four different planted forest types (Br ...

Abstract:
... Bark stripping by Asiatic black bears (Ursus thibetanus) has a serious impact on conifer plantations in Japan, resulting in physical damage to the tree trunks and reduction of the value of the timber. The aim of this study was to clarify whether these plantations are more prone to damage by bears at particular times and sites, to more effectively prevent this damaging behavior. The study was condu ...
