1. Kazuho Matsumoto, Kei Terasawa, Shingo Taniguchi, Mizue Ohashi, Ayumi Katayama, Tomonori Kume, Atsushi Takashima, Spatial and seasonal variations in soil respiration in a subtropical forest in Okinawa, Japan, ECOLOGICAL RESEARCH, 10.1111/1440-1703.12386, 38, 3, 479-490, 2023.05, To clarify soil respiration (soil CO2 efflux, R-s) characteristics in a subtropical evergreen broad-leaved natural forest in Yambaru, Okinawa, Japan, we examined spatiotemporal variation in R-s and its determining factors. We then compared yearly R-s with the value in other forests. The spatial variation in R-s (coefficient of variation [CV] = 38.9%) was not significantly related to temperature or soil water content but was evidently dependent on ground surface litter coverage. R-s was greater in summer (ca. 7-10 mu mol m(-2) s(-1)), and its seasonal variation was exponentially related to soil temperature (Q(10) = 2.16). As a function of soil temperature, we estimated a yearly mean stand-scale R-s of 5.17 mu mol m(-2) s(-1), and a total carbon efflux from the soil of 1959 g C m(-2) year(-1) for 2014. Despite showing similar seasonal patterns as those in temporal forests, the R-s in this ecosystem is very high throughout the year, and the yearly value is much higher for natural mature forests. A mass balance approach suggests that the large amount of belowground carbon allocation of plants contributed to the high CO2 emissions from the soils..

Hayato Abe, Ayumi Katayama, Shingo Taniguchi, Atsushi Takashima, Tomonori Kume, Kazuho Matsumoto, Effects of differences in aboveground dead organic matter types on the stand-scale necromass and CO2 efflux estimates in a subtropical forest in Okinawa Island, Japan, ECOLOGICAL RESEARCH, 10.1111/1440-1703.12317, 37, 5, 609-622, 2022.09, Dead organic matter (DOM), which consists of leaf litter, fine woody debris (FWD; = 28,750 m(2) and >= 2058-42,875 m(2), respectively, were required. Our results showed that CWD considerably contributed to stand-scale carbon stocks and efflux among aboveground DOM in this forest, resulting in a major source of errors in the stand-scale estimates..
3. Kobayashi Makoto, Pamela H. Templer, Ayumi Katayama, Osamu Seki, Kentaro Takagi, Early snowmelt by an extreme warming event affects understory more than overstory trees in Japanese temperate forests, ECOSPHERE, 10.1002/ecs2.4182, 13, 7, 2022.07, The occurrence of extreme warm events and early snowmelt is predicted to increase in high-latitude ecosystems, even during periods of time when there is no coincident reduction in total precipitation. However, because extreme events like these occur unpredictably, little is known about how advancing snowmelt by a single extreme warm event, without a reduction in precipitation amount, influences overstory trees and understory vegetation simultaneously in an ecosystem. We conducted a warming experiment (four 20 x 20 m plots) in temperate forests of Japan to determine the effects of earlier snowmelt on both understory dwarf bamboo plants and overstory birch trees. Our experimental treatment advanced snowmelt by about 10 days and increased soil temperatures that were associated with increased rates of soil nitrogen (N) mineralization and nitrification. Furthermore, these changes led to lower C:N ratios of leaves together with the greater growth of understory bamboo vegetation, with no changes in leaf C:N or growth rates of overstory birch trees. Together, our results demonstrate that advancing snowmelt by an extreme warm event in temperate forests is likely to affect N cycling and will benefit understory vegetation without a commensurate change in overstory vegetation, likely due to the increase in available soil N. These results also demonstrate that with the projected increase in the frequency of extreme warm events and advanced snowmelt, understory vegetation is likely to benefit more than overstory trees in Japanese temperate forests with heavy snow..

Yoshinori Shinohara, Shin'ichi Iida, Tomoki Oda, Ayumi Katayama, Kenji Tsuruta, Takanori Sato, Nobuaki Tanaka, Man-Ping Su, Sophie Laplace, Yoshio Kijidani, Tomonori Kume, Are calibrations of sap flow measurements based on thermal dissipation needed for each sample in Japanese cedar and cypress trees?, TREES-STRUCTURE AND FUNCTION, 10.1007/s00468-022-02283-3, 2022.04, Key message As the estimated parameters differed across samples, even from the same site, sample-based calibration is the recommended procedure. A trait-based approach (i.e., the use of structural parameters of the trees) would be an alternative procedure. The thermal dissipation method (TDM) is widely used for estimating transpiration by individual trees or stands. Although the importance of TDM calibration experiments is widely recognized, there is still no consensus on whether the calibration should be undertaken in practice for each species, site, or tree sample. The primary reason is that intraspecific variations in the fitting parameters have not been well examined in multiple sites. To address this, we performed TDM calibration experiments using 24 Cryptomeria japonica and Chamaecyparis obtusa samples collected from six regions in Japan and Taiwan. The sap flux density (F-d) based on the original TDM parameters was underestimated for most samples. Using a common set of parameters for 21 samples reduced the systematic underestimation. In addition, root mean square error (RMSE) was reduced by 44%. Site- and sample-based calibration reduced the RMSE by 69% and 75%, respectively. The estimated parameters for the samples varied, even among samples obtained from the same site. The recommended procedure is to obtain sample-specific parameters by performing a calibration experiment after measuring F-d under the target conditions. An alternative procedure is to use the parameters for other trees of the same species at the same site. Further, we discovered that one of the two parameters determined for each sample significantly correlated with the diameter/age ratio and height of the corresponding tree. A trait-based approach for predicting calibration parameters based on associated tree features allows the parameters to be determined without the need for calibration experiments..

Uchida, Ayumi Katayama, Yuko Yasuda, Tsutomu Enoki, Kyoichi Otsuki, Shinya Koga, Yasuhiro Utsumi, Age-Related Changes in Culm Respiration of Phyllostachys pubescens Culms With Their Anatomical and Morphological Traits, Frontiers in Forests and Global Change, 10.3389/ffgc.2022.868732, 5, 2022.04, Compared to trees, little is known about the respiratory characteristics of bamboo, especially culm respiration. In this study, we measured the respiration rates of current year, 2, 3, and above 4-year-old Moso bamboo (Phyllostachys pubescens) culms and examined its relation to culm morphology and anatomical structure. Current year culms had substantially higher respiration rates (1.9 ± 0.46 μmol m–2 s–1) compared to older culms (2, 3, and above 4-year-old average: 0.17 ± 0.09 μmol m–2 s–1). Culm wood density increased with age, with the concurrent thickening of parenchyma cell walls in the culm tissue. Nitrogen content in the culm tissue decreased with culm age. Both culm wood density and nitrogen content had significant relationships with culm respiration rate. On the other hand, culm height, wall thickness, and circumference did not affect culm respiration rate. Although bamboo culms did not change in size through the year, anatomical changes in the culm tissue that accompanied the aging of a culm affected the respiration. The culm age would have a significant effect on the evaluation of the respiratory characteristics of the bamboo forest. Our results suggested that young culms required a large amount of respiration to grow “inward” as cell wall thickening and also to maintain the relatively large amount of active tissue..

17. Aboveground biomass in managed and unmanaged bamboo forests for Phyllostachys pubescens and Phyllostachys bambusoides
本稿は,福岡演習林内の放棄モウソウチクおよびマダケ林に設置した,管理放棄したプロット(コントロール区)とタケノコ採取を行ったプロット(処理区)における4年間の地上部バイオマスのモニタリング結果を報告する。本研究の竹林の地上部バイオマスは両種とも,同じ福岡演習林内に生育する森林に比較すると低かった。コントロール区における新規稈数,および処理区におけるタケノコ採取数は明確な2年周期はなく,地上部バイオマス増加量は年変動が非常に大きかった。4年間の地上部バイオマス増加量平均値は森林と比較すると非常に高く,放棄竹林であっても生産性は森林よりも高いことが明らかとなった。一方,タケノコ採取により地上部バイオマスの減少が確認できたが,タケノコ採取数は減少しなかった。モウソウチク,マダケともに新規稈数の年変動が大きいことから,今後はさらに長期間のモニタリングが必要であることが示唆された。This report presents results of four-year monitoring of aboveground biomass in a control plot (i.e., abandoned forest) and a treatment plot (i.e., bamboo shoot harvested forest) for a Moso bamoboo forest (Phyllostachys eduli)) and a Madake bamboo forest (Phyllostachys bambusoides) in Kasuya research forest. Aboveground biomass in control and treatment plot was lower than broad leave forests in Kasuya Research forest. Two-year cycle for new culm and harvested bamboo shoot was not observed and inter-annual variation in aboveground biomass increment was very high. Aboveground biomass increment was higher than those for forests in Kasuya research forest, suggesting that abandoned bamboo forests have very high productivity. Bamboo shoot harvest decreased aboveground biomass, but did not affect number of harvested bamboo shoot. High inter-annual variation in new culms suggests that longer-time monitoring is necessary to examine dynamics of bamboo forest..
