In this study, two plots in a secondary and another two in planted Pinus densiflora stands were exposed to different forest treatments, and the ectomycorrhizal (EM) biomass and its ergosterol content was measured for a year. The unmanaged plot in the

To better understand soil carbon cycling in forest ecosystems, we studied the proportion of fungal sheath area (FSA) in the cross-sectional ectomycorrhizal area in 13 tree species. Ectomycorrhizal samples were collected from subalpine and temperate f

Fine-root turnover is an important component of forest carbon dynamics. We detail the characteristics of the minirhizotron method of measuring fine-root turnover and discuss its methodological implications. Minirhizotron data are relative values prop

In forest ecosystems, fine roots have a considerable role in carbon cycling. To investigate the seasonal pattern of fine root demography, we observed the fine root production and decomposition processes using a minirhizotron system in a Betula-domina

In terrestrial ecosystems, mycorrhizal fungi are considered to have important role on carbon cycling and its biomass has been studied to quantify their role. We noted why mycorrhizal fungi are important on carbon cycling and focused one of the key fa

At the first report of this series, we reconfirmed the importance of the study to quantify the role of mycorrhizal fungi in forest carbon cycling. In this report, we focused on the ergosterol analysis method, a general method to quantify the biomass

We estimated the role of mycorrhizal fungi quantitatively in a Japanese red pine (Pinus densiflora) forest. We directly estimated several parameters to calculate the amount of carbon consumed by mycorrhizal fungi, such as the biomass of fungi in ecto

Winter CO2 emissions from soil and snow-covered surfaces can represent a significant fraction of the annual carbon cycle in cool-temperate broad-leaved deciduous forests. The sources of this CO2 production are, however, poorly understood. To clarify

We conducted field and culture experiments to study the effects of arbuscular mycorrhizal (AM) fungi on the establishment of the alien plant Oenothera laciniata (Onagraceae) in a coastal sand dune in Japan. We examined the distribution of plants, AM
