The vascular cambium is the main lateral meristem responsible for secondary growth of trees. There are a number explicit and implicit assumptions behind this statement which allow questions to be raised about mechanism underlying radial Based on hypothesis diurnal strains plant organs, it anticipated that process can understood as an adaptation cyclically changing mechanical stress in direction...

We present a microhistological key for identification of plant fragments consumed and partially digested by free-roaming, forest cervids based on collection 92 species representing forage availability the Western Carpathian forests. The represents determination tool to facilitate analyses faecal ruminal material. summarized, integrated, developed current knowledge microstructures plants Cervida...

Assessing forest stand conditions in urban and peri-urban areas is essential to support ecosystem service planning and management, as most of the ecosystem services provided are a consequence of forest stand characteristics. However, collecting data for assessing forest stand conditions is time consuming and labor intensive. A plausible approach for addressing this issue is to establish a relat...

The close-to-Nature management method of interplanting broad-leaved trees after thinning monoculture plantations is an important mixed species restoration model to improve the ecological service and functions effectively as well reduce productivity decline multi-generation continuous planting monoculture. Thus, selection tree for establishing forest its adaptability are key issues. In this stud...

Charcoal from archaeological contexts differs off-site pollen samples as it is mainly a product of intentional human action. As such, analysis charcoal excavations valuable addition to studies past vegetation and the interaction between humans environment. In this paper, we use dataset consisting 6186 dated tree species 1239 sites proxy explore parts Holocene forest development human-vegetation...

The dieback of common ash (Fraxinus excelsior L.) has dramatically decreased the abundance species in Europe; however, tolerance trees varies regionally. is considered to be a result synergy genetic and environmental factors, suggesting an uneven future potential populations. This also implies that wide extrapolations would biased local information needed. Survival during 2005–2020, as well sta...

PACs (polycylic aromatic compounds) are air pollutants formed in incomplete combustion, e.g., vehicle engines. Vegetation can potentially remove substantial amounts and act as bioindicators of these pollutants. Increased knowledge the pollutant removal efficiencies different tree species is essential for understanding potential benefits trees provide urban residents. We investigated leaf/needle...

Accurate tree positioning and measurement of structural parameters are the basis forest inventory mapping, which important for biomass calculation community dynamics analyses. Portable backpack lidar that integrates simultaneous localization mapping (SLAM) technique with a global navigation satellite system receiver has greater flexibility than terrestrial laser scanning, but it never been used...
