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:
... Knot-related defects are important criteria for timber grading of valuable tree species. Clear-wood production through pruning has been an important issue in silviculture and forest management. In this study, knot attributes, branch occlusion and discoloration under natural and artificial pruning were investigated in a 10-year-old Betula alnoides plantation to determine the effectiveness of artifi ...

Abstract:
... Forest management affects stands’ vegetation structure, which influences bird communities. Since the effects of forest practices are usually more pronounced if the exotic tree species are planted, we surveyed bird communities and mapped the vegetation structure in stands of non-native broad-leaved and coniferous trees, black locust and black pine, in a central European country, the Czech Republic. ...

Abstract:
... In the dry forests of the western United States frequent fires historically maintained a diversity of habitats in multiple seral stages. Over the past century, fire suppression and preferential harvest of large trees has led to a densification and homogenization of forests, making them more prone to larger and more severe wildfires. In response, fuel reduction treatments have become common practic ...

Abstract:
... Rainforest restoration is an important application in today’s multipurpose management of secondary forest. However, our knowledge of tree species’ traits and responses to treatment is insufficient for foresters to make good decisions for sustainable management. The aim of our study was to see whether it is possible to predict tree species’ responses to increased light based on species’ traits, and ...

Abstract:
... We present a long-term quantitative analysis of forest damage caused by the brown bear (Ursus arctos) in the biggest refuge of this species in Poland. Based on questionnaires distributed to the relevant authorities we estimated the number of trees damaged by bears in 1991–2013, changes in the tree species composition and large-scale factors potentially affecting the extent of damage. We also discu ...

Abstract:
... In water-limited regions, adaptive management of forest and water relationships has been put forward, to implement hydrology-oriented silviculture to reduce stand evapotranspiration and, at the tree level, to improve growth and water use efficiency (WUE). The main goal of this study was to evaluate the effect of thinning in the short and medium term on tree growth, climate (drought) sensitivity, W ...

Abstract:
... Tropical dry forests are highly endangered ecosystems that have been scarcely studied. Many species within these forests suffer regeneration problems due to unsustainable management regimes. In particular, a regeneration problem has been detected in a forest of tara (Caesalpinia spinosa), a neotropical tree of high ecological and economic value, in Atiquipa (Peru). The study of the spatial pattern ...

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 ...

Abstract:
... Little is known about sustainable forest management and tree growth in the Amazon forest. Reliable growth data from trees are very important in the context of forest management. Tree-characteristics such as architecture and competition are associated with diameter growth. Previous studies analyzing tree growth have indicated that these variables can describe these effects for temperate and boreal ...
