A thorough understanding of carbon storage patterns in forest ecosystems is crucial for forest management to slow the rate of climate change. Here, we explored fine-scale biomass spatial patterns in a...
This study aimed to evaluate the seasonal variations of Greenhouse Gas fluxes (CH4, CO2, and N2O), Greenhouse Gas (GHG) emissions, and Global Warming Potential (GWP) over the extent of the regions and...
Land abandonment and secondary forest succession have played a significant role in land cover changes and forest cover increase in mountain areas in Europe over the past several decades. Land abandonm...
This study used 45 permanent sample plots investigated in 2007 and 6 permanent sample plots investigated in 2008 in Maoer Mountain natural secondary forest area and 68 permanent plots investigated in...
We surveyed the initial stage of a Platypus quercivorus infestation in a secondary forest dominated by Quercus serrata and Q. variabilis. Forty-three of 646 Q. serrata and 49 of 645 Q. variabilis tree...
Root biomass and surface area were estimated using two methods in a broad-leaved secondary forest in southern part of Kyoto Prefecture. Root systems (n=6) were dug out as samples. Dry weights and diam...
The stand structure of a secondary forest established on the Osaka group and related factors were analyzed. Twenty-seven quadrats were set in the forest, and every tree in those quadrats was measured....
Nowadays, under conditions in which forest areas are being opened with increasing number of forest roads due to great need for forest resources, the need for a well-kept system of forest roads becom...
Developing forest management plans for sustaining the full range of forest values is a challenging task. One of the difficulties in this process is to set and achieve management objectives, and conser...
The biogenic volatile organic compound (BVOC) composition of ambient air at a rural field site near Djougou, Benin has been studied as part of the AMMA (African Monsoon Multidisciplinary Analysis) pro...
