Global changes such as increasing CO2, rising temperature, and land-use change are likely to drive shifts in litter inputs to forest floors, but the effects of such changes on litter decomposition remain largely unknown. We initiated a litter manipulation experiment to test the response of litter decomposition to litter removal/addition in three successional forests in southern China, namely ma...

It is widely recognized that the long-term growth of forests benefits biomass carbon (C) sequestration, but it is not known whether the long-term growth of forests would also benefit soil C sequestration. We selected 79 representative soil profiles and investigated the influence of the forest stand age on the soil C dynamics of three soil layers (0-10, 10-20 and 20-30 cm) in temperate broadleav...

Remote sensing capabilities to monitor evergreen broadleaved vegetation are limited by the low temporal variability in greenness signal. With canopy computed from digital repeat photography (PhenoCam), we investigated how related seasonal changes leaf age and traits as well variation of trees’ water fluxes (characterized sap flow conductance). The results showed that sprouting leaves mainly res...

Four new Hydnellum species are described. roseoviolaceum sp. nov . grows in dry pine heaths on acidic, sandy soil. It is close to H. fuligineoviolaceum , another pine-associated species, but differs by smaller spores, an initially rose-coloured instead of violet flesh fresh basidiomata and a mild taste. scabrosellum coniferous forests calcareous shares general morphology with scabrosum which al...

The aim of this study was to delimit potential rockfall propagation zones based on simulated 2 m resolution trajectories using Rockyfor3D for block volume scenarios ranging from 0.05–30 m3, with explicit inclusion the barrier effect standing trees, an area approx. 7200 km2 in Switzerland and Liechtenstein. For determination start cells, as well slope surface characteristics, we used terrain mor...

Soils harbor a vast diversity of soil microbiota, which play crucial role in key ecosystem processes such as litter transformation and mineralization, but how complex plant-soil interactions shape the composition microbiota remains elusive. We performed amplicon sequencing DNA isolated from mineral topsoil six common European trees planted multi-site garden monoculture stands broadleaved maple ...

Individual tree crown (ITC) delineation in temperate forests is challenging owing to the presence of broadleaved species with overlapping crowns. Mixed coniferous/deciduous characteristics that differ type thus require a flexible method delineation. The ITC based on multi-criteria graph (MCG-Tree) addresses this problem monospecific or mixed by combining geometric and spectral information. was ...

In order to comprehend detailed forest resources, the use of high spatial resolution data is expected. However, the efficeint forest cover type classification method of high spatial resolution data is not cleared yet. So, this study discussed the potential of the forest cover type classification such as classification of coniferous forest, broadleaved forest, and mixed forest, and tree speices ...

Silver birch (Betula pendula Roth) is a popular tree species forming stands in nearly the whole of Europe. In Poland, one most representative broadleaved growing on rather poor soils, very often as mix with Scots pine (Pinus sylvestris L.). Central Europe, forms trunk sweeps, and at older age thick branches. Due to that, harvester thinning operation can be challengeable when trying process logs...

Rainfall interception by vegetation plays an important role in the hydrological cycle. Next to rainfall characteristics, is influenced tree size, crown structure and bark morphology. How traits determine across functionally morphologically wide-ranging species poorly understood. We determined ratios (interception:gross precipitation) canopy storage capacities of seven temperate deciduous broadl...
