    Quantifying cultural ecosystem services (CESs) has been difficult using traditional methods such as questionnaires, so increasing numbers of studies are utilizing big data obtained from social media for evaluation of CESs. Although data obtained from social media are often considered to be biased and non-representative, the actual effects of biases on evaluations of CESs are rarely quantified. In this study, we sampled posts from a microblogging service, Twitter, and investigated the effects of demographic biases on three indicators capturing aspects of social media which can be used for evaluations of CESs (spatial distribution, sentiment of post, and travel cost), focusing on the Japanese national parks as a case study. We found that Twitter users obtained from the randomly sampled 1% posts had a different distribution of demographic attributes (age, sex, and residential prefecture) from the Japanese population. More importantly, we found that activities on the platform such as estimated frequency of georeferencing and posting are different among demographic groups. This indicates that spatial distribution of CESs commonly evaluated by the number of georeferenced posts can be affected by additional demographic biases which cannot be captured by statistics based on all users on social media platforms. On the other hand, among the three indicators, only spatial distribution was strongly affected by the demographic attributes of users, indicating that the potential effects of biases are different for each indicator tested. These results clearly show that consideration of demographic attributes and their potential effects would be necessary to obtain representative and inclusive evaluations of CESs.

    Under the J-Credit Scheme, the amount of certified carbon credits generated from forest management (forest credits) has been increasing every year. However, many of them remain unsold. In this study, we aimed to clarify the characteristics and motivations of forest credit buyers and to examine issues to activate forest credit trading. We sent questionnaires to 179 forest credit buyers from six forest management projects in Niigata Prefecture, of which 96 responded. Most of the forest credit buyers were small and mid-sized companies that aimed to contribute to the local forest. The amounts of credits they bought were also small, mostly less than 5 t-CO2. Most of the buyers were encouraged to buy forest credits by either prefectural officials, the credit creators, or intermediaries (coordinators) such as local banks. Among these, coordinators were effective in obtaining new buyers and expanding sales channels. However, many of the buyers who were encouraged by coordinators bought only small amounts of credits and were less willing to continue buying. In contrast, buyers who actively learned about forest credits without being encouraged by others were more willing to continue buying larger amounts of credits. Thus, in order to activate forest credit trading, it would be effective to increase efforts to motivate buyers who were encouraged by coordinators, and to increase opportunities to catch the attention of companies that are willing to contribute to the forest environment.

    The urgency to conserve and restore forests for their multifaceted benefits is escalating. We spotlight Japan's new Forest Environment Tax, a novel fiscal measure crafted to finance public‐beneficial ecosystem services through enhanced forest management.

    To convey the expert perceptions of the policy, we present the results of a survey targeting individuals immersed in Japan's forest policies, which aimed to assess attitudes toward the various benefits that forests provide. We classified forest functions into five core areas: wood production, soil and water conservation, mitigation of anthropogenic global warming, wildlife conservation and cultural utilities.

    We found that stakeholders closely involved in forest policies in Japan prioritize soil and water conservation as the paramount function over the mitigation of anthropogenic global warming. The results of the survey underscore the necessity of evaluating forest management practices and the importance of recognizing the multiple values that can be derived from forests. While there has been much attention to the carbon benefits of forests in the region and beyond, we emphasize the need to avoid an excessive focus on this single ecosystem service and to ensure that the other important multifunctional values of forests are not overlooked.

    Policy implications: We call for a more holistic approach that recognises the interdependence of the different functions of forests and the importance of valuing forests as natural capital in all their dimensions.

    Mountain streamwater chemistry is an effective indicator of forest condition. In 2022, we conducted a nationwide investigation of mountain streamwater chemistry in Japan, leveraging citizen‐participatory sampling. This approach involved 629 individuals with regular exposure to mountain and natural environments. Although our primary aim was to sample at locations from a 2003 study, we also welcomed samples from new sites. In total, 1414 streamwater samples were collected one time from each forested watershed at the baseflow condition. Our study focused on stream nitrate (NO<sub>3</sub><sup>−</sup>) concentration as a key indicator of anthropogenic nitrogen (N) loading impacts on forests. We compared NO<sub>3</sub><sup>−</sup> concentrations in 2022 with those from 2003 at identical sampling points. After excluding 179 points with evident human‐created features upstream, the mean NO<sub>3</sub><sup>−</sup> concentration in 2022 was 0.328 mg N L<sup>−1</sup> (n = 1236). Comparing data from 1088 points sampled in both years, the mean value in 2022 (0.324 mg N L<sup>−1</sup>) was significantly lower than that in 2003 (0.359 mg N L<sup>−1</sup>, p &lt; 0.05). Notably, 88.5% of sampling points showed differences within ±0.25 mg N L<sup>−1</sup>. The spatial distribution pattern of mountain stream NO<sub>3</sub><sup>−</sup> concentrations in 2022 did not consistently align with large cities, industrial areas, or N deposition sources. This unique approach marked the first nationwide participatory survey for collecting mountain streamwater in Japan. Our success in ensuring sample quality through accessible explanations, manuals, and videos demonstrates the potential of citizen science. However, the quantitative evaluation of scientific accuracy remains a forthcoming challenge.

    In this study, we examined roles of three vegetation characteristics in provisioning of a recreation service by applying a machine-learning method to 4,708,229 spatially-explicit records of hiking activity in Japan. Then, expected impacts of land-use changes assessed and mapped based on the model. Associations between a recreation service and three vegetation characteristics were considerably variable depending on the social and natural environment such as accessibility and altitude. As a consequence, expected impacts of unit changes in vegetation characteristics on the service flow were considerably heterogeneous throughout the study area. The signs (positive or negative) of the impact can be reversed depending on the contexts even among nearby sites. Such notable but variable contributions of vegetation on a recreation service should be carefully reflected in landscape management. Even moderate changes in either the quantity or quality of vegetation can have a considerable impact on the frequency of hiking activity. Landscape management for promotion of the recreation service should be carefully designed for each locality on the grounds of the context-dependent effects of vegetation.

  • Plant characteristics drive ontogenetic changes in herbivory damage in a temperate forest Reviewed International journal

    Understanding ontogenetic differences in plant defenses and herbivory damage is crucial for obtaining a better understanding of plant life-history strategies, community assembly, and dynamics. Although many studies have compared plant defenses or herbivory damage between ontogenetic stages (e.g. sapling vs. adult), how the effects of plant characteristics on leaf herbivory damage change during plant ontogeny has rarely been examined across species or in a species-rich natural community.
    To elucidate the effects of plant characteristics, we compared the relationships of leaf herbivory by insects with stem density, plant size, and leaf traits between saplings and adults for almost all co-occurring woody species (56 species, ranging from rare to abundant) in a Japanese temperate forest.
    In most species, adults were larger, fewer in number, and had leaf traits that were potentially less favorable to herbivores (e.g. stronger, or with more phenolics). In contrast, we observed species-specific directions of changes in herbivory damage between adults and saplings with plant phylogeny or density having no clear effect. The relationships between some plant traits and herbivory damage were ontogeny dependent, indicating a shift from chemical to physical defense as plants mature, although most of the species characteristics studied were highly correlated between stages. Such ontogeny-dependent relationships between plant traits and herbivory damage could cause variation in the ontogenetic changes in herbivory damage among species depending on the value of plant traits. Moreover, the direction and magnitude of the effects of ontogenetic differences in species traits on the ontogenetic differences in herbivory damage varied depending on the traits. Together, these factors could have caused the observed ontogenetic changes in herbivory damage among species.
    Synthesis. Our study demonstrated how relationships between plant characteristics and herbivory damage can change ontogenetically across many coexisting woody species in a forest community, suggesting that plant traits may perform different functions related to herbivory at different ontogenetic stages. This has rarely been considered in previous dualistic comparisons of individual traits and herbivory damage between ontogenetic stages, and it is vital for understanding plant life-history strategies across stages in relationships with herbivores in natural communities.

    Japanese cedar (Cryptomeria japonica) is the most important timber species in Japan; however, its pollen is the primary cause of pollinosis in Japan. The total number of pollen grains produced by a single tree is determined by the number of male strobili (male flowers) and the number of pollen grains per male strobilus. While the number of male strobili is a visible and well-investigated trait, little is known about the number of pollen grains per male strobilus. We hypothesized that genetic and environmental factors affect the pollen number per male strobilus and explored the factors that affect pollen production and genetic variation among clones. We counted pollen numbers of 523 male strobili from 26 clones using a cell counter method that we recently developed. Piecewise Structural Equation Modeling (pSEM) revealed that the pollen number is mostly affected by genetic variation, male strobilus weight, and pollen size. Although we collected samples from locations with different environmental conditions, statistical modeling succeeded in predicting pollen numbers for different clones sampled from branches facing different directions. Comparison of predicted pollen numbers revealed that they varied &gt;3-fold among the 26 clones. The determination of the factors affecting pollen number and a precise evaluation of genetic variation will contribute to breeding strategies to counter pollinosis. Furthermore, the combination of our efficient counting method and statistical modeling will provide a powerful tool not only for Japanese cedar but also for other plant species.

    Understanding how the ecological properties of a landscape yield ecosystem services is essential for sustainable management and sound decision-making. For cultural ecosystem services, however, it is not always clear whether the ecological attributes of a landscape are responsible for heterogeneity in service provisioning. In addition, seasonal and scale-dependent changes in effects of landscape attributes have rarely been examined. To answer these questions, we analyzed associations between various landscape attributes and a proxy of a cultural ecosystem service, that is, monthly number of hiking records for 1953 mountains in Japan crowdsourced from a social networking service for hikers. Landscape attributes were summarized at five spatial scales from a 5- to a 100-km radius from a summit. The effect of primary vegetation on frequency of hiking activity was positive at a spatial scale of 5 km in many months and was especially important in early summer and autumn, whereas the effects of total vegetation cover were generally not important. The positive effect of mountain height was dominant in summer, whereas the positive effects of population density at 50 and 100 km were dominant in winter. The height of a summit relative to the highest point in the surrounding area was important at the intermediate (10 and 20 km) scales. As a whole, seasonal and scale-dependent changes in the relationships between most of the landscape attributes and number of hiking records were apparent. Such changes should be carefully considered in future studies on cultural ecosystem services.

    Resprouting is one of the life-history strategies of plants in response to disturbance, and is related to functional traits of leaves and wood. Previous studies have shown that shade-tolerant species, characterized by higher leaf dry matter content (LDMC), leaf thickness, leaf toughness, and wood density, tend to have lower resprouting ability (Shibata et al. 2014). However, it remains unclear whether these relationships hold not only among species but also within species. This study aims to clarify how intraspecific variation in leaf and wood functional traits is related to sprouting ability, and to compare these patterns with interspecific relationships.
    The study surveyed 248 individuals of eight woody species in a beech forest in Niigata Prefecture, Japan. In June 2024, we measured the diameter of the stems and then cut them off at the base. At that time, leaf and wood samples were collected to measure LDMC, specific leaf area, leaf thickness, leaf toughness and wood density. In October, we recorded the number, basal diameter and height of all sprouts emerging from each stump. We constructed GLMMs using the probability of sprouting, number of sprouts, total basal area of sprouts, and maximum height of sprouts as response variables. Explanatory variables included stem basal area and functional traits. Species were included as a random effect on both intercepts and slopes.
    LDMC and leaf thickness had significant positive effects on the total basal area of sprouts, indicating that individuals with sun-leaf traits such as higher LDMC and thicker leaves tended to produce greater sprouting biomass within species. This pattern is opposite to the interspecific trend, where shade-tolerant species with higher LDMC tend to have lower sprouting ability. These results suggest that the mechanisms influencing sprouting ability differ between intra- and interspecific levels.

    To understand the adaptive significance of resprouting ability, the size dependency of resprouting ability after stem clipping for 24 deciduous trees at Ogawa Forest Reserve was formulated and correlated to functional traits and life history traits.

    All studied species resprout as juveniles, but many trees lost resprouting ability after attaining a particular size. The ontogenetic changes in resprouting ability for each species were described with three parameters, Initial sprouting ability (Rsap), Size of maximum sprouting (Rmax), and Increasing rate of sprouting ability. Rsap was negatively correlated with maximum basal area and specific force to punch leaf, and positively with size distribution index (SDI); higher SDI indicates disturbance dependent. Species with relatively large Rmax had higher SDI than species with relatively small Rmax.

    These results suggest that disturbance dependent trees have high resprouting ability as juveniles and keep resprouting ability until adults, and they may adapt to infrequent fire. Disturbance independent trees, in contrast, resprout only as juveniles, indicating resprouting as adults is less important. Shrubs had high resprouting ability throughout life, and frequent stem alternation may be adaptation to frequently disturbed site.

    多くの木本植物は、地上部が撹乱などにより失われた際に萌芽再生する能力を持っている。萌芽発生量はある特定の株サイズでピークを持っており、その萌芽特性は樹種ごとに異なっている。一般に萌芽には地下資源への投資が必要とされており、様々な生活史特性とトレードオフが発生していると考えられる。本研究では、まずそれぞれの樹種がどのような萌芽特性を持っているのかを明らかにし、その上で萌芽特性に影響を及ぼしている生活史特性を探った。

    北茨城市小川群落保護林周辺の伐採１年目の２次林皆伐跡地にて調査を行った。調査は地下資源を用いた萌芽の成長が終わり、独自に光合成成長を開始する前と考えられる６月から８月上旬の初夏の間に行った。落葉高木１２種、落葉小高木３種を対象とし、株サイズの異なる個体を１種あたり１８－３８個体を選び、切り株断面の直径と地際からの高さ、萌芽枝の根元直径と長さを測定した。

    親株の断面積（S）と発生萌芽断面積の合計（P）との関係をP=aSb-cS（a,b,cは定数）という式を用いて回帰することで、ある株サイズで萌芽発生量のピークを持つ曲線を得ることができ、回帰パラメータが樹種特有の萌芽特性を示していた。さらに、これまで小川試験地で得られた生活史特性に関するデータを用いて萌芽特性と生活史特性との関係を考察した。

    2026.3   日本生態学会第73回全国大会   種内及び種間における木本樹種の萌芽能力と機能形質の関係性

    　More details

    Award type：Award from Japanese society, conference, symposium, etc. 

    萌芽は攪乱に対する植物の生活史戦略の一つであり，葉の機能形質とも関係している。先行研究では，耐陰性樹種は萌芽能力が低い傾向があることが示されており(Shibata et al. 2014)，これらの樹種はLDMC（Leaf dry matter content），葉の厚さ，物理的強度が高い特徴を持つ。しかし，こうした関係が種間だけでなく，種内の個体差においても成立するかは明確ではない。本研究では種内における葉の機能形質と萌芽能力の関係性を解明するとともに，種間における萌芽能力と機能形質の関係性との違いを検証することを目的とした。
    調査は新潟県のブナ林で行い，主要16樹種548個体を対象とした。2024，2025年6月に幹直径を計測後，根本から伐採した。伐採時に同個体の葉を採取し，LDMC，SLA（Specific Leaf Area），葉の厚さ，葉の物理的強度を計測した。同年10月に各株の萌芽の根本直径，高さを計測した。解析は萌芽の合計基底断面積，最大高を応答変数とし，幹直径より求めた株断面積，各機能形質，年度を説明変数としたGLMMを構築した。いずれも樹種をランダム効果に含めた。種間関係は，萌芽を株断面積から予測するGLMMに各樹種の平均株断面積を入力して得た樹種別予測値と，樹種平均形質の相関で評価した。
    種内では萌芽の合計基底断面積に対してLDMC，葉の厚さの有意な正の影響，SLAの有意な負の影響が示され，高いLDMCや厚い葉などの陽葉形質を持つ個体ほど萌芽再生量が多い傾向が各樹種に共通してみられた。一方，種間では萌芽の合計基底断面積とLDMCの間で有意な強い負の相関が示され，LDMCの大きい耐陰性樹種ほど萌芽再生量が小さかった。以上の結果は，機能形質が萌芽能力に影響する仕組みが種内と種間で異なる可能性を示唆する。当日は種内，種間で萌芽能力と機能形質の関係性が逆転することについて議論する。

    ブナ林低木層の構成樹種にとって，林冠ギャップ形成や雪圧害，動物の被食などによる損傷後の萌芽再生は重要な生活史戦略である。本研究では，伐採から1および2成長期後の萌芽応答に対する光環境と攪乱季節の影響を評価し，それらが常緑樹種と落葉樹種でどのように異なるのかを明らかにした。本研究は新潟県魚沼市のブナ二次林で，落葉11種・常緑5種の16樹種を対象に冬・春伐採を行い，萌芽枝の有無，本数，合計基底断面積，最大高を測定した。解析は，8樹種の萌芽応答を1・2成長期後まで追跡し林分単位の光環境を計測したデータ(N＝317)と，16樹種の1成長期後の萌芽応答および個体単位の光環境を計測したデータ(N=423)を用い，光環境，伐採季節，株サイズ，常緑・落葉を説明変数とするベイズGLMMを構築した。1成長期後の萌芽の合計基底断面積および最大高には，伐採後の光環境と冬伐採の有意な正の影響がみられたが，2成長期後は光環境の影響のみが残った。以上から，撹乱季節の影響が萌芽初期には強いが，長期的には光環境の影響がより強くなると示唆された。また，冬伐採の正の効果は常緑樹より落葉樹で大きく，撹乱季節に対する萌芽応答の落葉樹・常緑樹間の差が示された。

    2025.7   The 11th EAFES International Congress   Intra- and interspecific relationships between sprouting ability and functional traits of woody species in a Japanese beech forest

    　More details

    Award type：Award from international society, conference, symposium, etc. 

    Resprouting is one of the life-history strategies of plants in response to disturbance, and is related to functional traits of leaves and wood. Previous studies have shown that shade-tolerant species, characterized by higher leaf dry matter content (LDMC), leaf thickness, leaf toughness, and wood density, tend to have lower resprouting ability (Shibata et al. 2014). However, it remains unclear whether these relationships hold not only among species but also within species. This study aims to clarify how intraspecific variation in leaf and wood functional traits is related to sprouting ability, and to compare these patterns with interspecific relationships.
    The study surveyed 248 individuals of eight woody species in a beech forest in Niigata Prefecture, Japan. In June 2024, we measured the diameter of the stems and then cut them off at the base. At that time, leaf and wood samples were collected to measure LDMC, specific leaf area, leaf thickness, leaf toughness and wood density. In October, we recorded the number, basal diameter and height of all sprouts emerging from each stump. We constructed GLMMs using the probability of sprouting, number of sprouts, total basal area of sprouts, and maximum height of sprouts as response variables. Explanatory variables included stem basal area and functional traits. Species were included as a random effect on both intercepts and slopes.
    LDMC and leaf thickness had significant positive effects on the total basal area of sprouts, indicating that individuals with sun-leaf traits such as higher LDMC and thicker leaves tended to produce greater sprouting biomass within species. This pattern is opposite to the interspecific trend, where shade-tolerant species with higher LDMC tend to have lower sprouting ability. These results suggest that the mechanisms influencing sprouting ability differ between intra- and interspecific levels.

    ブナ二次林において持続的な用材生産を実現させるためには間伐後にブナ実生による更新を確実にする必要がある。間伐直後の林分では林床の光環境は大幅に改善されるが，間伐からの年数経過に従って林床の光環境は悪化する。2023年の春から秋にかけてブナ当年生実生を対象に行った調査により，間伐直後の林分では当年生実生の生存・成長および冬芽サイズなどの翌年以降の投資量が大幅に増加するが，間伐からの年数が経過した林分では減少するという結果が得られた。そこで本研究では特に当年生実生の冬芽サイズに着目し，継続調査として2年生実生を対象に春の伸長量・展葉枚数・葉面積を調査することにより，当年生時の光環境が2年生時の成長に与える影響を明らかにすることを目的とした。その結果，当年生時の光環境が良好で冬芽サイズが大きいほど2年生時の伸長量，展葉枚数は増加するという結果が得られ，2年生時及びそれ以降の実生の生育に大きな影響を与える可能性が示唆された。発表当日は葉面積の解析も踏まえ光環境勾配に対する実生の成長特性にも着目しながら，その後の実生の生育について考察したい。

    National parks are important as places for nature conservation and nature-tourism. However, it is difficult to balance these two functions, which has created many conflicts. Thus, sustainable use of national parks has become a challenge. If we show that protecting nature and ecosystems increases the satisfaction of tourists, we can prove that nature conservation has a great impact on human well-being.

    In recent years, many tourists have been uploading nature photos to social networking services (SNS) and enjoying them with a lot of “likes”. Thus, we thought that the number of "likes" obtained by posting a photo on SNS can be used as an indicator of the level of satisfaction of the tourists.

    In this study, all 34 national parks in Japan were included in the analysis. The national park area was divided into three zones according to the level of protection by the Ministry of Environment. We used Twitter, one of the most popular SNS in Japan. We collected metadata of geo-tagged Twitter photos taken in national parks between 2018 and 2020. We also collected metadata of geo-tagged Twitter photos taken outside of national parks by the same users who posted inside national parks. We used generalized linear mixed model to analyze the impact of the level of protection of the geo-tagged location of the photo on the number of “likes”.

    The number of “likes” increased significantly for photos taken in national park zones with a higher level of protection. The results showed that in national park zones with higher levels of protection, tourists can take and post more attractive photos. In conclusion, this study showed that nature conservation in national parks has a significant effect on improving human well-being through posting attractive nature photos on SNS.

    親株の断面積（S）と発生萌芽断面積の合計（P）との関係をP=aSb-cS（a,b,cは定数）という式を用いて回帰することで、ある株サイズで萌芽発生量のピークを持つ曲線を得ることができ、回帰パラメータが樹種特有の萌芽特性を示していた。さらに、これまで小川試験地で得られた生活史特性に関するデータを用いて萌芽特性と生活史特性との関係を考察した。

    This study analyzed geo-tagged photos posted on social media to reveal following questions; (1) Is there a significant increase in the number of posts (i.e., increased number of cultural service users) during flowering periods around the colonies of beautiful spring plants (Hepatica nobilis, Lysichiton camtschatcensis, Erythronium japonicum)? (2) Does the content of the posted photo (content of cultural service usage) change seasonally? As a result, this study showed that the flowering of spring plants (1) contributed little to the increase in the number of users of cultural services, and (2) contributed significantly to the qualitative aspect of the use of cultural services (i.e., what kind of ecosystem elements are enjoyed by visitors).
