In this study, we aimed to develop height growth models using forest data with the measured total height, bole and diameter at breast targeting Robiniapseudoacacia plantations of various ages, located in restoration former mining areas a lignite center Northwestern Greece. To achieve goal, 24 circular plots were randomly established different ages. Eleven tested for fit, selection was based on ...
Long-term CO2 enrichment of a forest ecosystem: implications for forest regeneration and succession.
The composition and successional status of a forest affect carbon storage and net ecosystem productivity, yet it remains unclear whether elevated atmospheric carbon dioxide (CO2) will impact rates and trajectories of forest succession. We examined how CO2 enrichment (+200 microL CO2/L air differential) affects forest succession through growth and survivorship of tree seedlings, as part of the D...
To investigate chemical and color changes of the polymeric constituents of black locust (Robinia pseudoacacia) wood during heat treatment, extractive-free wood flour was conditioned to 30% initial moisture content (MC) and heated for 24 h at 120 °C in either an oxygen or nitrogen atmosphere. The color change was measured using the CIELAB color system. Chemical changes of the wood components wer...
