Despite growing evidence that diverse forests play an important role in ecosystem functioning, ensuring the provision of different services, whether such diversity improves their response to drought events remains unclear. In this study, we use a large tree-ring database from thirty case studies across nine European countries and eleven species, covering Mediterranean hemiboreal forests, test i...
Soil seed banks can act as an important source in forest regeneration, and the information on the seed bank composition is vital for determining the resilience of plant communities under severe environments such as urban settings. In this study, we examined the seed bank density and functional composition, and their relationships with aboveground vegetation in three remnant evergreen broad-leav...
A new genus, Diacanthomyia gen. nov. assigned to the subtribe Thyreophorina of the family Piophilidae is described based on a new species, Diacanthomyia okidoi sp. nov. recently found in Honshu and Kyushu, Japan. The new genus is somewhat similar to the European Centrophlebomyia of the subtribe. However, the new genus is distinguished from the known genera of the subtribe by the following combi...
Based on materials gained in March 2015 from the Forest Data Bank the survey of some attributes (forest address including Regional Directorate of State Forest (RDSF), area in hectares, soil unit, forest site type, dominant species in a forest stand and age of the dominant species in a stand) of post-agricultural lands occurring in Polish State Forests was conducted in the paper. Distribution of...
Typhoons are having an increasingly severe and widespread impact on forest ecosystems around the world due to climate change. However, few studies have examined impacts of strong typhoons subtropical evergreen broadleaved forests, particularly in rare old-growth forests. Here, using a 20 ha permanent plot Guangdong Province, southern China, super Typhoon Mangkhut secondary forests was quantitat...
Overwintering evergreen oaks reverse typical relationships between leaf traits in a species spectrum
The leaf economics spectrum has given us a fundamental understanding of the species variations in leaf variables. Across plant species, tight correlations among leaf mass per area (LMA), mass-based nitrogen (N m) and photosynthetic rate (A m) and leaf lifespan have been well known as trade-offs in leaf carbon economy. However, the regional or biome-level correlations may not be necessary to cor...

The response of soil respiration to acid rain in forests, especially in forests of different maturity, is poorly understood in southern China despite the fact that acid rain has become a serious environmental threat in this region in recent years. Here, we investigated this issue in three subtropical forests of different maturity [i.e. a young pine forest (PF), a transitional mixed conifer and ...
In order to better assess the spatial variability in subtropical forest biomass, the goal of our study was to use small-footprint, discrete-return Light Detection and Ranging (LiDAR) data to accurately estimate and map aboveand below-ground biomass components of subtropical forests. Foliage, branch, trunk, root, above-ground and total biomass of 53 plots (30 × 30 m) were modeled using a range o...
