Forest understories play a vital role in ecosystem functioning and the provision of services. However, extent to which environmental conditions drive dominant ecological strategies forest at continental scale remains understudied. Here, we used ~29 500 vegetation plots sampled across Europe classified into 25 types explore relative macroclimate, soil pH tree canopy cover driving abundance-weigh...

The late Early/early Middle Miocene flora from Parschlug (Styria, Austria) is famous for its numerous specimens and high diversity. Some taxa previously described are revised here 42 new angiosperm leaf morphotypes/taxa described. Climate Leaf Analysis Multivariate Program (CLAMP) applied to assess the palaeoclimate. An update of tool most suitable modern climate CLAMP calibration dataset intro...

This work develops methods to account for shoot structure in models of coniferous canopy radiative transfer. Shoot structure, as it varies along the light gradient inside canopy, affects the efficiency of light interception per unit needle area, foliage biomass, or foliage nitrogen. The clumping of needles in the shoot volume also causes a notable amount of multiple scattering of light within c...

Relative pollen productivity (RPP) is a key parameter for quantitative reconstruction of past vegetation cover. However, RPP estimates are rarely obtained in the subtropical and tropical regions. In this study, extended R-value (ERV) model was used to estimate major plant taxa evergreen broadleaved mixed forests middle China based on soil samples data from 23 sites. The best result with combina...

To understand the impact of climate change on tree radial growth in Southeast China’s subtropical evergreen broadleaved forest, comparative research growth–climate associations Schima superba was conducted. This dominant species examined at both its southern and northern distribution margins through dendroclimatology. The results showed that S. stands a high elevation margin were positively cor...

The structure of forests has changed with an increase in soft-wooded broadleaved species over the past decade. demand for hard-wooded can be met by replacing them compressed wood species. Existing technologies do not fully take into account density variations that exist along height a tree trunk. In this study, we examined variability birch and aspen microstructures trunk, including vessels per...

Litterfall, directly and indirectly, affects the soil physicochemical properties, microbial activity, diversity of fauna flora by adding organic matter nutrients to soil. This study explores litterfall dynamics such as production, litter decomposition rate, associated nutrient return in three forest types, that is, camphor tree (CTF), Masson pine (MPF), mixed (CMF), subtropical China. Results s...

Identifying emerging invasive species is a priority to implement early preventive and control actions. In terms of the number tree species, forestry represents second largest pathway introduction, with an debt likely existing for alien conifers in Europe. 1900s, network arboreta was established southern Belgium assess wood production potential prospective conifer broadleaved species. Here, we u...
