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:
... Knowledge about tree age is critical to forestry, nature conservation and ecological studies. Direct age determination of large diameter trees through increment cores is complicated by various obstacles, primarily because of rot and insufficient borer length. Here, we aim to (1) test the accuracy of various methods (tree-ring width, basal area increment, age-size relationship) for tree age estimat ...

Evaluation of ecosystem C storage in restored mangrove forests will provide important information for management and conservation practices, climate change mitigation strategies and reduction of emissions from deforestation and forest degradation (REDD+) schemes. Despite this, a gap remains in the understandin ...

Abstract:
... Observations of increasing global forest die-off related to drought are leading to more questions about potential increases in drought occurrence, severity, and ecological consequence in the future. Dry soils and warm temperatures interact to affect trees during drought; so understanding shifting risks requires some understanding of changes in both temperature and precipitation. Unfortunately, str ...

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 ...

... Tree microhabitats – e.g. cavities, bark pockets or crown dead wood – have been described as key habitat elements, which are particularly important for birds, bats and xylobiont insects. They are therefore vital for promoting biodiversity in forest ecosystems. The occurrence of such tree microhabitats in forest stands is closely related to forest management. In Central European cultural landscapes ...

In temperate forests of Central Europe, by contrast, the ecological role of fire has largely been neglected even though the high frequency of wildfires in naturally fire-prone forests is well documented. In this study, we focused on semi-natural forests dominated by Pin ...

Abstract:
... Management of boreal forests with clear-cutting has a marked effect on forest biodiversity. One directly and severely affected group of species is ectomycorrhizal fungi (EMF), because of their dependence on living host trees. Key questions in nature conservation and potentially for fungal ecosystem services are whether EMF communities as regenerated stands age will develop into a similar compositi ...

We quantified tree morta ...
