    Understanding the link between interannual variations in net primary production (NPP) and soil CO<inf>2</inf> efflux (R<inf>s</inf>) is essential for evaluating carbon dynamics in forest ecosystems, particularly in ecosystems such as Moso bamboo (Phyllostachys pubescens) forests with distinctive 2-year cycles of new shoot production. In this study, we measured NPP and R<inf>s</inf> components in a Moso bamboo forest over a 5-year period to clarify the consistency of their interannual variation patterns. Our results revealed significant year-to-year variations in NPP (CV = 41%), primarily attributable to above-ground productivity, while R<inf>s</inf> components (i.e. autotrophic (R<inf>a</inf>) and heterotrophic (R<inf>h</inf>) respiration) exhibited less year-to-year variations (CV = 10%–22%). Although NPP and R<inf>s</inf> did not exhibit synchronized interannual variations, we observed marginal positive correlations between litterfall, fine root production, and R<inf>a</inf> (Spearman’s correlation coefficient = 0.9, p < 0.1). These findings suggest that while current-year NPP components may influence R<inf>a</inf>, R<inf>h</inf> variations appear to be relatively independent from NPP variations in Moso bamboo forests. We discuss the simplification of net ecosystem production (NEP = NPP − R<inf>h</inf>) estimates in Moso bamboo forests for regional C assessment, highlighting the importance of long-term monitoring of above- and below-ground processes in these ecosystems.

    <jats:title>Abstract</jats:title><jats:p>Due to policies supporting large‐scale expansion of plantation forestry, about 40% of the forests in Japan are planted forests, such as Japanese cedar (<jats:italic>Cryptomeria japonica</jats:italic>) and hinoki cypress (<jats:italic>Chamaecyparis obtusa</jats:italic>). We present the largest freely available EcoPlate dataset for planted forests in Japan, comprising data collected from a network of 74 planted forest sites (114 plots) in regions ranging from cool‐temperate to subtropical. The EcoPlate is a 96‐well microplate that contains three sets of 31 “response wells” with different carbon substrates. The utilization of each carbon substrate by the microbial community is quantified based on the color development of the well during incubation, providing a multifunctional index of the soil microbial community. Soil properties (water content, carbon, nitrogen, the carbon/nitrogen (C/N) ratio, and pH) essential for interpreting the EcoPlate results were also analyzed. Using a standardized protocol, soil was sampled between July and November 2021. A preliminary principal coordinate analysis (PCoA) was performed on the temporal integration of color density using the 31 substrates. PCo1 explained 36.5% of the variance of the overall absorbance of all substrates. A model of environmental factors, including elevation, and a model of soil properties, including pH, water content, and carbon, were the best‐fit models. EcoPlate data allow us to test hypotheses related to community ecology and the ecosystem functions of the soil microbial community in planted forests on a regional scale.

    <p>Overpopulated ungulates reduce the biomass of understory vegetation and promote the expansion of unpalatable plants in world forests. Such understory degradation may influence soil respiration (<i>R</i><sub>s</sub>) and heterotrophic respiration (<i>R</i><sub>h</sub>). Here, we examined this possibility in one cool-temperate forest in southern Kyushu, Japan. At the study site, the dominant understory vegetation, dwarf bamboo (Sasa; <i>Sasamorpha borealis</i>), has been patchy lost and replaced by an unpalatable shrub, Asebi (<i>Pieris japonica</i>), owing to sika deer feeding. We targeted three understory vegetation types: Sasa understory (SU), no understory (NU), and Asebi understory (AU). The <i>R</i><sub>s</sub>, <i>R</i><sub>h</sub>, soil temperature, and soil volumetric water content (SVWC) were measured at three points in each understory type using an automatic opening/closing chamber system from August 2022 to November 2023. We then evaluated biotic and abiotic factors, including surface litter amount, fine root biomass, and soil physiochemical properties, to examine their effects on the temperature sensitivity proxy (<i>Q</i><sub>10</sub>) of <i>R</i><sub>s</sub> and <i>R</i><sub>h</sub>. Annual <i>R</i><sub>s</sub> and <i>R</i><sub>h</sub> were estimated using continuously measured soil temperature data and temperature-<i>R</i><sub>s</sub> and <i>R</i><sub>h</sub> relationships. The temporal variation of <i>R</i><sub>s</sub> and <i>R</i><sub>h</sub> was strongly affected by soil temperature and weakly by SVWC for all understory types. The spatial variation in <i>Q</i><sub>10</sub> of <i>R</i><sub>s</sub> and <i>R</i><sub>h</sub> was explained by fine root biomass and surface litter amount, respectively, regardless of understory type. Differences in annual <i>R</i><sub>s</sub> and <i>R</i><sub>h</sub> among understory types were comparable to those among measurement points in the same understory type. This was due to the similar soil temperature and <i>Q</i><sub>10</sub> of <i>R</i><sub>s</sub> and <i>R</i><sub>h</sub> among understory types. Thus, inner-site <i>R</i><sub>s</sub> and <i>R</i><sub>h</sub> variations could be generated by the spatial variations in soil biotic factors, regardless of understory vegetation type in our study site. This means our study cannot clearly verify whether overbrowsing increases <i>R</i><sub>s</sub> and <i>R</i><sub>h</sub>, highlighting the necessity for future research.</p>

    Among soil erosion processes, the initial stage of splash soil erosion caused by throughfall kinetic energy (TKE) plays a crucial role in soil conservation within forest ecosystems. Throughfall (TF) through the upper canopy structure considerably influences TKE in coniferous plantations. Recent studies have revealed that the under-canopy structure laden with dead branches in unmanaged coniferous plantations reduces the TF; however, its specific impacts on TKE and appropriate sampling strategies remain unexplored. This study used 40 splash cups (4 for free kinetic energy and 36 for TKE) for one event (total: 600 splash cups for 15 events) in an unmanaged 36-year-old Japanese cypress plantation laden with dead branches. Additionally, unstratified and stratified Monte Carlo simulations were used to determine optimal sample sizes for stand-scale TKE estimation. Results demonstrated a strong correlation between TKE (J m<sup>−2</sup>) and TF (mm) (R<sup>2</sup> = 0.98) across all events. The stand-scale unit TKE of 12.5 J m<sup>−2</sup> mm<sup>−1</sup> was much lower than those in seven previous studies with fewer or no dead branches (range: 16.4 to 28.2, median: 18.8 J m<sup>−2</sup> mm<sup>−1</sup>). The previously developed empirical stand-scale unit TKE model considering under-canopy structure solely exhibited a 1.7-fold overestimation. Among the stand structures, a positive relationship of TKE with the distance between a sampling point and its nearest trunk (D<inf>min</inf>) was observed, which was positively correlated with the lowest dead branch height. This indicated that under-canopy dead branches weakened the TKE, likely by reducing TF and raindrop fall velocity. Stratified Monte-Carlo simulation considering the D<inf>min</inf> related spatial patterns of TKE provided a more efficient approach for capturing variability. To achieve high precision with potential errors of ≤5–10 %, a total sample size of 6–15 was appropriate. Our findings implied that the presence of under-canopy dead branches mitigates the soil erosion risk in unmanaged Japanese cypress plantations.

    Ununiform, excessive, and prolonged understory vegetation feeding by overpopulated ungulates (over-browsing) leads to heterogeneous stand structural alterations at the landscape level. However, it is not yet clear how changes in various types of stand structural alterations affect total carbon (C) stocks in forest ecosystems as the sum of aboveground C stocks (AGC) and belowground C stocks (BGC). We aimed to fill this gap in a cool temperate broadleaf–conifer mixed forest in southern Kyushu, Japan, where over-browsing of sika deer has occurred since 1980. Four replicate survey plots were established in four stand types, namely, stands with presence of understory vegetation (PU), stands with no understory vegetation (NU), stands dominated by unpalatable shrubs (SR), and stands with canopy gap areas with a lack of regeneration (CG). Using PU as a baseline, alterations in stand structure (e.g., stem density) and C stocks were evaluated for each stand type. We measured C stocks of overstory trees (height > 2 m), understory vegetation, leaf litter, fine woody debris (FWD), and coarse woody debris (CWD) as AGC. C stocks of fine roots, coarse roots, and soil organic matter (SOM) at 0–30 cm depths were measured as BGC. We also separated overstory trees according to the palatability of the deer diet. The alteration from PU to NU did not reduce AGC, BGC, or total C stocks. The alteration from PU to SR and CG was found to potentially reduce total C stocks and AGC by up to 49% and 59%, respectively. These reductions in SR and CG were mainly driven by the decreased C stock of palatable overstory trees. There were dense unpalatable shrubs in SR and large amounts of CWD in CG. However, neither was sufficient to offset the loss of palatable overstory trees in SR and CG. We also found a reduction in the C stock of leaf litter and SOM at 0–10 cm depth in NU, SR, and CG. These reductions were likely caused by reduced litterfall and increased soil erosion, implying future reductions in BGC. Our results suggest that stand structure conservation is a key guideline for C stock retention when implementing forest management strategies to prevent over-browsing. The failure to conserve palatable juvenile trees could lead to a lack of more palatable overstory trees in the future, causing irreversible changes in AGC and BGC.

    The overpopulation of large herbivorous mammals degrades understory vegetation and hence promotes soil erosion in some northern hemisphere forests. Topsoil removal via erosion reduces soil water and nitrogen (N) content as well as exposes tree roots. However, whether topsoil removal inhibits tree growth through water and N uptake limitations has not been examined. This study aimed to measure the vertical length from exposed roots surface to the soil surface (exposed root height; ERH) under degraded forest understory vegetation and to evaluate its influence on tree growth. Specifically, we examined the relationships between ERH and beech growth and identified the timing of growth reduction based on annual tree-ring analysis at the individual scale. Furthermore, we discussed the effects of water and N limitations on beech growth reduction. We studied 12 Japanese beech trees on Mt. Sanpo, southern Kyushu Island, Japan, where understory vegetation was degraded and lost due to herbivory by Japanese sika deer from 1980 to 2003. Lower amounts of leaf production and relative growth rates of stem basal area increment (BAI) were observed in beech trees with higher ERH. Segmented regression analysis, which detects the changing time of a temporal trend (i.e., break-point), revealed that the BAI has resulted in a decreasing trend after 1997.6 ± 9.0 (yr), which coincided with the field observations on understory degradation in the study site. After the break-point of the BAI, the BAI of each study tree was negatively related to intrinsic water use efficiency, an integrated index of water limitation. These results suggest that soil erosion after the degradation of understory vegetation reduced beech growth, possibly because of the water limitations associated with root exposure. Reduced beech growth will reduce the supply of the litter layer that prevents topsoil erosion, which may enhance further soil erosion and tree growth reduction.

    Abstract. The degradation of ground vegetation cover caused by large grazing herbivores frequently results in enhanced erosion rates in forest ecosystems. Splash erosion can be caused by drop impacts with a high throughfall kinetic energy (TKE) from the tree canopy. Notably larger canopy drips from structurally mediated woody surface points appear to induce even higher TKE and generate concentrated impact locations causing severe focus points of soil erosion. However, TKE at these locations has rarely been reported. This pilot study investigated the intensity of TKE at a concentrated impact location and compared it with general TKE locations under the canopy and freefall kinetic energy (FKE) outside the forest. We measured precipitation, TKE and FKE using splash cups at seven locations under Japanese beech trees and five locations outside the forest during the leafless and leafed seasons in 2021 in a mixed forest with evergreen coniferous trees and deciduous broadleaved trees in Japan. The TKE at the concentrated impact location was 15.2 and 49.7 times higher than that at the general locations under the beech and FKE, respectively. This study confirmed that canopy drip from woody surfaces could be a hotspot of soil erosion in temperate forest ecosystems. Throughfall precipitation at the concentrated impact location was 11.4 and 8.1 times higher than that at general locations and freefall, respectively. TKE per 1 mm precipitation (here, “unit TKE”) at the concentrated impact location (39.2 ± 23.7 J m−2 mm−1) was much higher than that at general locations (22.0 ± 12.7 J m−2 mm−1) and unit FKE (4.5 ± 3.5 J m−2 mm−1). Unit TKE in the leafless season was significantly lower than in the leafed season because of fewer redistribution of canopy drips induced only by woody tissue. Nevertheless, unit TKE at the concentrated impact location in the leafless season (36.4 J m−2 mm−1) was still higher than at general locations in the leafed season. These results show that potentially high rates of sediment detachment can be induced not only by throughfall precipitation but also by larger throughfall drop size distributions at the concentrated impact location, even in the leafless season. Further studies with more replication building on this first report are necessary to investigate how many of these concentrated impact locations may occur on average with different tree species to better assess the extent of the erosion risk under forests.

    Carbon dioxide and water vapor exchanges between tropical forest canopies and the atmosphere through photosynthesis, respiration, and evapotranspiration (ET) influence carbon and water cycling at the regional and global scales. Their inter- and intra-annual variations are sensitive to seasonal rhythms and longer-timescale tropical climatic events. In the present study, we assessed the El Niño-Southern Oscillation (ENSO) influence on ET and on the net ecosystem exchange (NEE), using eddy-covariance flux observations in a Bornean rainforest over a 10-y period (2010–2019) that included several El Niño and La Niña events. From flux model inversions, we inferred ecophysiological properties, notably the canopy stomatal conductance and “big-leaf” maximum carboxylation rate ( Vcmax25_BL ). Mean ET values were similar between ENSO phases (El Niño, La Niña, and neutral conditions). Conversely, the mean net ecosystem productivity was highest during La Niña events and lowest during El Niño events. Combining Shapley additive explanation calculations for nine controlling factors with a machine-learning algorithm, we determined that the primary factors for ET and NEE in the La Niña and neutral phases were incoming shortwave solar radiation and Vcmax25_BL , respectively, but that canopy stomatal conductance was the most significant factor for both ET and NEE in the El Niño phase. A combined stomatal-photosynthesis model approach further indicated that Vcmax25_BL differences between ENSO phases were the most significant controlling factor for canopy photosynthesis, emphasizing the strong need to account for ENSO-induced ecophysiological factor variations in model projections of the long-term carbon balance in Southeast Asian tropical rainforests.

    Characteristics of isoprene emission from moso bamboo leaves in a forest in central Taiwan
    © 2019 Elsevier Ltd The expansion of moso bamboo (Phyllostachys edulis) may potentially impact regional isoprene emissions. Modeling based on field measurements is an effective approach for assessing the potential impact of the moso bamboo expansion. The G93 algorithm is one of the most widely used models, however no studies have tested the applicability of the algorithm for moso bamboo isoprene emission. This study was undertaken to establish a model for reproducing moso bamboo isoprene emission fluxes. To this aim, this study examined 1) the isoprene emission ability of moso bamboo, and 2) its responses to environmental factors such as leaf temperature and light. We also tested 3) the reproducibility of the G93 algorithm for moso bamboo isoprene emission fluxes. This study used a chamber method with a modified photosynthesis system and carbon absorbents to quantify isoprene emitted from bamboo leaves in central Taiwan under the humid subtropical climate. First, we screened isoprene emission from 12 bamboo species, and the results confirmed that moso bamboo exhibited significant isoprene emission potential. Second, we measured isoprene emission fluxes from moso bamboo leaves with light controls every month from summer to spring. The isoprene emission fluxes increased with photosynthetic photon flux density (PPFD); under sufficient PPFD conditions, the seasonal changes in the isoprene emission fluxes were regulated by leaf temperature, and low isoprene emission fluxes were found in low leaf temperature conditions. Thirdly, overestimations were observed in the G93 algorithm with the original parameters in periods with leaf temperatures <23 °C. Using the G93 algorithm with site-specific parameters could improve the overestimation in the low-temperature period. This study suggests the necessity of parameterization in the G93 algorithm to reproduce the suppression of isoprene emission fluxes from moso bamboo leaves in the low-temperature period.

    Effects of soil water decline on diurnal and seasonal variations in sap flux density for differently aged Japanese cypress (Chamaecyparis obtusa) trees
    © 2018, Editura Silvica. All rights reserved. The effects of soil drought on transpiration are often neglected when predicting transpiration for forests in humid regions under the influence of the Asian monsoon. These effects have indeed been neglected for Japanese cypress, Chamaecyparis obtusa, a major plantation species in Japan and the surrounding area, probably because previous studies have reported no clear effects of soil drought on transpiration for Japanese cypress forests. However, a few studies have reported an apparent reduction in transpiration with soil drought for young Japanese cypress forests. It remains unclear whether such a reduction in transpiration is limited to young Japanese cypress forests or if it is not uncommon for mature Japanese cypress forests, which occupy a large area in Japan. To clarify this point, we conducted sap flux measurements in a year with soil drought on three differently aged Japanese cypress stands including mature (43 years old) and relatively young (23 and 26 years old) trees. In a diurnal time scale, a cross correlation analysis of sap flux density (Fd) and vapor pressure deficit (VPD) showed that the time lags between Fdand VPD were 1-3 h in dry soil conditions. These were larger than those of wet soil conditions (<1 h) for all sample trees. Fdat a given VPD in dry soil conditions was smaller than that in wet soil conditions for all sample trees; a 28%–63% reduction in the rate of change in Fdwas observed under dry soil conditions. Because our results were obtained when the non-exceedance probability of recorded monthly precipitation was 9%–18%, the results suggest the need to consider the effects of soil drought more extensively. Those effects should be considered for not only relatively young but also mature Japanese cypress when predicting diurnal and seasonal patterns of transpiration in years with soil drought, and when predicting inter-annual patterns of transpiration for Japanese cypress despite humid temperate climate.

    Applicability of Sap Flux Measurements in Moso Bamboo (Phyllostachys pubescens): Relationship between Water Absorption and Whole-tree Water Use Utilizing Granier Sensor Sap Flux Measurements.
    Although sap flux measurement is one of the most robust techniques for stand-scale transpiration estimates, its applicability to bamboo is unclear. Ultimately we aim to establish a method for sap flux-based stand-scale transpiration estimates in a bamboo forest. This study focused on establishing a method for individual-scale transpiration estimates. We conducted sap flux measurements using hand-made 1-cm length sensors, and water absorption measurements in cut-bamboo. The sensors could detect water uptake in individual plants(i.e., sap flux in moso bamboo). The diurnal changes in sap flux density reasonably well corresponded to those in water absorption. We found there was an underestimation of whole-tree water use with the 1-cm Grainer sensor; thus we suggested a modified equation for the calculation of sap flux density. In this study we could estimate individual-scale transpiration in moso bamboo using sap flux measurements.

    Effects of Coniferous Plantation Thinning on Annual Interception Evaporation: Model Verification.
    For evaluating the effect of coniferous plantation thinning on water resources, our previous study (Komatsu et al., 2007c) developed a model for predicting changes in annual evapotranspiration caused by coniferous plantation thinning. This model is comprised of transpiration and interception evaporation parts. The model needs to be verified from three viewpoints, stability of transpiration amounts with thinning, decrease in interception evaporation amounts with thinning, and applicability of the model to catchment scale. This study mainly focused on verification of the interception evaporation part. Based on seven datasets of interception evaporation derived from earlier publications, we compared model prediction results with the observed results. Model prediction results agreed fairly well with the observed results, indicating validity of the interception evaporation part of the model. Based on one dataset for verifying applicability of the model to catchment scale, model prediction results agreed fairly well with the observed results, implying applicability of the model to catchment scale. We should note that validity of the transpiration part of the model was not examined. Applicability of the model to catchment scale was not fully examined due to lack of observation data. Thus, we raised observation data that should be required for further model verification and presented guidelines for future observation studies.

    Contemporary Role of Catchment Water Balance Data for Forest Evapotranspiration Research.
    Recently, catchment water balance measurements have not been used actively for examining forest evapotranspiration compared to process-based measurements based on meteorological and sap-flow methods. This paper overviewed the history of forest evapotranspiration studies and clarified what caused this situation. This paper then pointed out that catchment water balance measurements cannot be replaced completely by process-based measurements from the viewpoints of data accuracy and feasibility of measurements. This paper also pointed out that coordination of process-based measurements and catchment water balance measurements brings new insights. Furthermore, this paper proposed several important topics that should be examined by such coordination and also proposed measures to develop environments that promote such coordination.

    Relationships between Forest Properties and Evapotranspiration Rates.
    We identified problems in clarifying relationships between forest properties (e.g., broad-leaved/coniferous, canopy height, etc.) and evapotranspiration rates, and then proposed a plan to solve the problems. Furthermore, we showed how much the plan has accomplished. The problems were such that the generality of observation results is unclear. That is, it is unclear whether observation results at a site are applicable to other sites. We pointed out that developing a model that expresses evapotranspiration rates as functions of meteorological conditions and site parameters is useful for examining the generality of observation results. Then, we developed a model and described the model structure. For using the model, four examinations are required: 1) dry-canopy evaporation rates in a growing season, 2) wet-canopy evaporation rates in a growing season, 3) seasonal pattern of dry-canopy evaporation rates, and 4) seasonal pattern of wet-canopy evaporation rates. We have completed the examination of dry-canopy evaporation rates in a growing season using the Priestley-Taylor coefficient (α), and obtained the following two conclusions. First, α values for broad-leaved forests tend to be higher than those for coniferous forests. Second, α values for coniferous forests relate to canopy height.

    Differences in Diurnal Pattern of Transpiration between Young Sugi Trees (Cryptomeria japonica) Located at the Ridge and the Bottom of a Slope
    On a mountainous slope, sap flow velocities in sugi trees (Cryptomeria japonica) located at the ridge and the bottom of the slope were measured using heat pulse sensors. Meteorological factors were also observed at the ridge and the bottom of the slope. Time lag in sap flow velocities was observed between trees at the ridge and the bottom of the slope when transpiration began to occur after sunrise or rainfall. Usually, transpiration occurred earlier at the ridge of the slope than at the bottom. The average value of the time lag was 58.5min. Additionally, differences in meteorological factors between the ridge and bottom of the slope were observed. The average and variation of the time lag were larger after sunrise than when rain ceased in afternoon. The time lag was highly correlated with differences in both vapor pressure deficit and shortwave radiation between the ridge and the bottom of the slope. Thus, we suspected that differences in both vapor pressure deficit and shortwave radiation between the ridge and the bottom of the slope caused differences in the time lag after sunrise.

    九州大学演習林内では、里山を代表する森林タイプである モウソウチク林、スギ林、広葉樹林 において、炭素吸収量（NPP）の長期モニタリングを行っている。本研究では、土壌炭素・養分蓄積の計測技術を有する Han 氏 と新たに共同し、これらの森林における 土壌呼吸（Rs） を詳細に計測する。炭素の 吸収量（NPP） と 放出量（Rh・Ra を含む土壌呼吸） の差し引きから、各森林の 炭素固定量（NEP） を算出し、その違いを比較する。さらに、吸収と放出の 環境応答特性をモデル化 し、気候変動予測値を用いて 将来の NEP を予測 することで、里山の炭素吸収を強化するための方法論を確立する。

    気候変動により予測される熱帯地域の降水パターンの変化は、森林の持つ様々な生態系サービスの発揮、ひいては地球環境にも甚大な影響を及ぼす。特に、今後発生リスクの増大が予想されるエルニーニョ現象による強度乾燥は、熱帯雨林に壊滅的ダメージを与える恐れがある。本研究は、①操作実験による強度乾燥時の個体レベルの遺伝子発現、生理応答、分光反射特性を明らかにし、②熱帯雨林を構成する多様な樹種の乾燥耐性能力を評価し、ストレス適応型の樹種や系統を探索する。③個体・樹冠レベルの分光反射特性を踏まえて過去の乾燥時の人工衛星データを解析し、乾燥に対する広域での植生応答や回復力の時空間モニタリング技術の開発を行う。

    生態系では人間にとって望ましくない「異常な」状態への変化が急激に生じることが多く、その変化を早期に検知するための警戒指標の開発が急務である。従来の指標は、生態系を生物の均一な集団とみなすような単純化と複数の安定状態の存在の前提に基づくため有効性が低い。そこで本研究では、「生態系の巨視的特性がその構成要素間の相互作用により創発的に決まる」という微視的過程に着眼した早期診断法の構築を目指す。湖沼・農地・森林をモデルケースとして、微視的特徴づけ(1.少数の生物個体・小さな空間における変化、2.構成要素間の相互作用強度の変化)に基づく新たな早期警戒指標を開発する。
