    Scientific journal, Abstract

    Monitoring tropical ecosystem services such as carbon stock and biodiversity with satellite remote sensing is essential for addressing climate change and biodiversity loss, but collecting ground truth data is costly. We investigated whether Unmanned Aerial Vehicles (UAVs) can reduce the costs. First, we developed a method to estimate Above-Ground Carbon (AGC) and biodiversity index (mixing ratio of pioneer and late-successional species) based on data derived from UAV-RGB images in four Forest Management Units (FMUs) in Malaysia. Second, we tested whether adding UAV-based ground truth (i.e., estimated carbon and biodiversity index) improves satellite-based models. We built machine learning models to estimate AGC and biodiversity index based on Landsat metrics and inventory data across Malaysia and Indonesia (395 plots). Accuracy was low without local inventory data (287 plots outside the four FMUs; R 2  = 0.43 and 0.46 for AGC and biodiversity, respectively). Adding UAV-based data ( n  = 934) significantly increased the accuracy ( R 2  = 0.51 and 0.48), which was comparable to the model with the full dataset including local inventory data ( R 2  = 0.53 and 0.60). These results underscore that integrating UAV and satellite analyses facilitates the monitoring of ecosystem services in tropical forests by reducing costs while maintaining accuracy.

  • Exploration capacity versus specific enzymatic activity of ectomycorrhizas in response to primary productivity and soil phosphorus availability in Bornean tropical rainforests
    Kei-ichi Okada; Daiki Yokoyama; Shin-ichiro Aiba; Kanehiro Kitayama
    Scientific Reports, 14, 1, Springer Science and Business Media LLC, 03 Feb. 2024
    Scientific journal, Abstract

    Ectomycorrhizal (ECM) fungi are functionally important in biogeochemical cycles in tropical ecosystems. Extracellular enzymatic activity of ECM on a ground-area basis is the product of two attributes; exploration capacity (ECM surface-area) and specific enzymatic activity. Here, we elucidated which attribute better explained the ECM enzymatic activity in response to different levels of soil phosphorus (P) and Nitrogen (N) availability in five Bornean tropical rainforests. We determined the surface area of ECM root tips as well as the enzymatic activities per ECM surface area for carbon (C), N and P degrading enzymes in each site. We evaluated the relationship of ECM enzyme activities with the resource availabilities of C (Above-ground net primary production; ANPP), N, and P of ECM by a generalized linear mixed model. The ECM enzymatic activities on a ground-area basis were more significantly determined by specific enzymatic activity than by the exploration capacity. Specific enzymatic activities were generally negatively affected by C (ANPP) and soil P availability. ECM fungi enhance the specific enzyme activity rather than the exploration capacity to maintain the capacity of nutrient acquisition. The less dependence of ECM fungi on the exploration capacity in these forests may be related to the limitation of C supply from host trees. We highlighted the adaptive mechanisms of ECM fungi on nutrient acquisition in tropical ecosystems through the response of enzymatic activity to nutrient availability across the elements.

    Scientific journal, Abstract

    Interspecific relationships between growth and survival are critical determinants of tree species diversity maintenance in forests. The trade‐offs between growth and survival in co‐occurring tree species are believed to arise along a continuum of life‐history strategies. For example, co‐occurring species range from those that grow slowly and survive well in resource‐poor environments to those that grow quickly but have low survival rates in resource‐rich environments. However, uncertainties remain regarding how growth–survival trade‐offs are related to species traits, tree sizes or environmental conditions.

    We examined how the relationships between species traits and growth–survival relationships shift in response to changes in stem sizes and across census periods with different climate conditions (frequency of strong winds, drought intensity) across 45 co‐occurring tree species based on 23 years of growth and survival records in a warm temperate rainforest on Yakushima Island, Japan. We developed hierarchical Bayesian models of relative growth and survival rates, including leaf traits, wood density and 95‐percentile maximum stem diameter as explanatory variables. We tested the relationships between estimated trait‐mediated growth–survival relationships and the indices of climate events during five census periods.

    Each trait's effects on growth–survival relationships differed across the five census periods in response to climate conditions. Interspecific growth–survival relationships affected by a single trait axis for leaves or wood tended to be negative. In contrast, those affected by the maximum stem diameter tended to be positive. Such trends increased with more frequent strong winds or more intense droughts. The single‐trait effects on growth–survival relationships were stronger for smaller sizes than for larger sizes. For all traits combined, we found a significant growth–survival trade‐off only for small‐sized stems in three of five census periods.

    Synthesis. Our results indicate that the effect of species traits on the growth–survival relationships depended on tree sizes, the census periods or both in response to the frequency or intensity of climate events. We argue the importance of incorporating spatial and temporal variations in environmental conditions into long‐term data from tree census to predict forest dynamics.

    古い地質を持つボルネオ島などでは多様な熱帯降雨林生態系が成立している。その要因として、生元素として最も重要な窒素（N）とリン（P）の時空間的な非対称性が考えられる。NもPも生物の代謝や遺伝に普遍的に関わっているが、土壌風化プロセスの過程で、２つの元素のうちどちらかが欠乏する時空間的なパターンが生じる。さらに、元素欠乏に対して、樹木はNとPの間で異なる応答を示す。地球化学的なNとPのアンバランスと生物学的な応答の非対称性が組み合わさることにより、多様な生態系が形成される可能性が高い。本研究は、安定した地質を持ち、生物地球化学的な反応速度の速いボルネオ島熱帯降雨林を精査することにより、この独創的な仮説を検証する。本年度は以下を実施した。
    マレーシア・サバ州（ボルネオ島）において、堆積岩起源の土壌上に成立している熱帯降雨林に複数の調査区を設定し、各調査区において土壌断面を5か所掘削し、表層の有機物層から下層に向けて土壌サンプルを採集した。採集した土壌は、サバ州内の共同研究施設に持ち帰って、前処理を行った。また、各調査区で優占樹種を選択し、陽葉と材サンプルを各種4個体から採集し、冷蔵して実験室に持ち帰った。一部サンプルは凍結乾燥し保管、さらに残りのサンプルについては熱風乾燥し粉砕後に日本に持ち帰った。陽葉と材の熱風乾燥サンプルの一部については、硫酸・過酸化水素により湿式灰化し、ICPにより全P濃度を、比色法により全N濃度を決定した。

    マレーシアなどの木材生産林の一部では、過去の無秩序な伐採により森林を荒廃させた反省から、持続可能な森林管理の実践的手法として低インパクト伐採が行われている。この方法は年間収穫量を従来の数十パーセント以下に抑えるほか、残存木の損傷や地表撹乱にも配慮している。低インパクト伐採の効果については、これまで森林地上部を中心に研究されてきた。しかし、伐採インパクトの違いが、森林地下部の現存量回復にどのような影響を及ぼすかという問題は、未解明なまま残されている。ボルネオ熱帯林における伐採インパクトの違いが細根現存量の回復時間に及ぼす影響とその要因を明らかにするため、マレーシア・サバ州のMaliau Basin森林保護区の原生林と、その周辺地域で過去に伐採が行われた森林を対象に、調査区設定のための候補地選定と樹木のサイズ計測を行った。混交フタバガキ林の原生林に設置した既存の調査プロットで毎木調査を実施したところ、原生林に特徴的なL字型のサイズ分布となっていた。また、胸高直径5 cm以上の個体を対象とした胸高断面積合計は48.8 m2/ha、地上部現存量は484.6 Mg/haと推定された。保護区周辺部の伐採が行われた森林では、地元の森林事務所スタッフらの情報提供により、2015年に低インパクト伐採が行われた場所と、2010年に従来型伐採が行われた場所を候補地として選定した。現地の状況を確認したところ、低インパクト伐採の森林は、場所によって状況が異なるものの原生林の樹種組成がある程度保たれているようであった。従来型伐採の森林では、多くの個体につる植物が繁茂し、個体を覆っているため、生育が阻害されている場所が目立った。以上のように、原生林、従来型伐採、低インパクト伐採の森林間比較を行うための基盤整備を進めた。

    Large within-species variation is observed in sessile organisms, such as forest trees, shrubs and intertidal barnacleｓ. Dealing with those systems consisted of multiple species, this study examined the relationship between within-species, among-individual variations of life-history measures (in particular, size-dependent growth) and among- species coexistence. We quantified within-species variation using long-term repeated census records, applying bias-free new methods. Life-long integration of variation characterized species-level turnover rates. The fast-slow trade-off among species facilitated the equitability mechanism of coexistence.

  • Mechanisms of conifer dominance in tropical forests: life history, hydraulics and soil nutrition

    Conifers of families Podocarpaceae and Araucariaceae can become dominant in mountains and on nutrient-poor soils in tropical forests which are otherwise dominated by angiosperm trees. Conifer dominance increases on more nutrient-deficient soils. On soils with intermediate fertility, conifers are 'long-lived pioneers', which regenerate during rare disturbance events and reside in canopy for a long time. On severely nutrient-deficient soils, conifers regenerate continuously. We suggest that soil fertility affects the growth of angiosperm trees, which modifies the light environments in the forest, and thereby determines conifer dominance. Apparently drought-resistant characters in conifers seem to reflect the adaptation to nutrient deficiency.

    We studied the issue of invasive plants into nature reserve area of West Java, Indonesia. We found about 30 invasive plants, Clidemia hirta, Eupatoriumspp. in herb layer, and Maesopsis eminiiin tree layer seemed to threaten the native vegetation. Quinine and teak do also in some areas. Schima wallichiiwhich is often planted to reconstruct native vegetation was diversified weakly in the region, thus the possibility that plantations disturb the genetic diversity seemed to be low.

    For the purpose of evaluating coexistence mechanisms of tree species in tropical and subtropical rain forests in South-East Asia, we estimated demographic and allometric parameters in terms of community-wide and species-specific Bayesian probability distributions by employing long-term forest-plot census data. Based on estimated parameters we examined inter-specific trade-offs in demography and allometry. We evaluated contributions of detected trade-offs and disturbance-responses to coexistence by means of the analysis of stratified competition model.

    It was predicted that the concentration of soil phosphorus was low due to soil weathering and the residual soil phosphorus would not be available to biota due to its strong sorption with weathered soil minerals in the inland tropical rain forest ecosystems in Borneo. We widely surveyed Borneo and selected forest ecosystems of low phosphorus availability. We studied the ecophysiology of phosphorus-use efficiency and phosphorus acquisition efficiency of trees as well as the roles of soil microbial communities to elucidate the mechanisms of long sustainability of such phosphorus-limited rain forests.

    相場 慎一郎
    本研究は、東アジアの多雨林の純一次生産量の長期変動を明らかにすることを第一の目的としている。植物は光合成によって二酸化炭素を固定して有機物を生産している。この総生産量から呼吸による損失量を差し引いた量が純一次生産量であり、地上部については、森林の現存量(幹と大枝)の増加分+葉や小枝の生産量として定義される。森林の現存量の増加分は樹木サイズの継続測定によって既存の経験式を用いて推定できる。葉や小枝の生産量を直接測定するのは困難であるが、原生的森林では生産量と死亡量がつり合うと仮定できるので、リター(落葉・落枝)量の測定によって推定できる。温帯と熱帯の調査地を比較することで、地理変異についても明らかにすることが第二の目的である。これまで、リター量については、キナバル山では共同研究により8年間におよぶデータが蓄積され、屋久島では申請者自身により6年間のデータが揃っている。リター量は年変動が大きく、平均値の推定と長期変動パターンの検出には長期間の調査が必要とされる。そこで、本年度も、屋久島で引き続きリタートラップによるリター量のモニタリングをおこなった。リタートラップにたまった落葉・落枝は申請者がおおよそ月1回のペースで回収し、葉・繁殖器官・枝・その他に分別して乾重を測定した。6年間調査した4か所の調査地の間には、同調した年変動が見られ、最大の年は最小の年の1.4-1.5倍の速度を示した。リターの内訳を見ると、繁殖器官の同調性が顕著であった。

  • Investigation of the relationships between tree-specdes diversity and the functions of tropical rain forests

    The objectives of this study are to understand the control of the functions of tropical rain forests by tree-species diversity. In order to achieve this goal, we took an innovative approach in that we compared two naturally species-rich (Malaysia) versus species impoverished (Hawaii) tropical rain-forest regions. The working hypothesis was that a greater species pool (i.e. regional species diversity) could provide more nutrient-use efficient species to reduced nutrient availability while a impoverished species pool would provide lesser nutrient-use efficient species to reduced nutrient availability leading to a temporally variable biomass in response to nutrient availability. To test this working hypothesis, we set up one soil chronosequence in each region, along which soil nutrient availability changed due to soil aging and associated geochemical processes. We investigated the above-ground net primary productivity and nutrient-use of the major tree species in each region. The adove-ground net primary productivity was estimated by repeated measures of secondary growth of trees plus litter-fall rate which was measured bi-weekly. The intact leaves were collected from the major trees in each site and wet-digested to analyze foliar minerals. In Hawaii where regional species richness (i.e. species pool) was small, above-ground net primary productivity and biomass increased with increasing soil nitrogen availability towards a peak stage where soil nitrogen and phosphorus were abundant, followed by an abrupt decline phase where soil phosphorus availability declined. By contrast, such an abrupt change did not occur in Malaysia because more phosphorus-use efficient species replaced inefficient species with declining soil-phosphorus availability. Thus our working hypothesis was accepted.

    To study the maintenance mechanism of biodiversity on Borneo Island, we conducted research in Merimbun Heritage Park, Mt. Kinabalu, Sabah, Betung Kerihun National Park, West Kalimantan, and Berau, East Kalimantan for 257 days. We made plots of 4ha in Brunei, 6-ha in Kalimantan, and 1.5ha for plant ecological study, and collected 2733 plant specimens. Lowland of Borneo Island is dominated by Dipterocarpaceae, but there are many kinds of Dipterocarpaceae forests. The species numbers of trees bigger than 4.8cm in DBH in 1-ha were ranged from ca 70 to 220, lowest in swamp, the second was riverbank forest, and forest on hill was most rich. The mechanism of coexistence was studied in congeneric species of Sterculiaceae, Meliaceae, and Palmae. Genetic diversity was studied in Licuala and Cyrtostachys of Palmae. The role of animals for seed dispersal was also studied.

  • 多雨林の樹木群集における多様性―生産性仮説の検証

    本研究は、多雨林の樹木群集について、野外データに基づき、生産性が高いほど種多様性が高いという多様性-生産性仮説を検証することを第一の目的とした。地上部の生産性は、積み上げ法によって葉の生産と地上部現存量回転速度の和として推定する。樹木種多様性がすでに明らかになっていて、葉の生産と地上部現存量回転速度の長期継続調査を行っているアジアの2か所の山岳(屋久島・マレーシア)をおもな対象とした。
    地上部の純一次生産速度を推定するために、鹿児島県屋久島(暖温帯多雨林)では、リタートラップをもちいてリター(落葉・落枝)を月1回回収し、葉・繁殖器官・枝・その他に分別して乾重を測定し、葉の生産速度を推定した。また、地上部の純一次生産の決定要因のひとつであるリターの分解速度を調査した。マレーシアのキナバル山(熱帯多雨林)では、調査区の樹木の幹直径を再測定し、地上部現存量回転速度を推定した。緯度傾度にそった解析のため、沖縄県西表島の亜熱帯多雨林でも調査区を設定した。以上のデータとこれまでに共同研究によって蓄積されたデータにもとづき、広域スケール(緯度・標高傾度)での多様性-生産性関係について検討した。
    以上の成果のうち、マレーシアで得られた結果の一部は、共著論文として学術誌で発表した。おもな内容は、かんばつが森林の生産性に与えた影響(Aiba ＆ Kitayama 2002)、調査区の樹木組成と種数-面積関係(Aiba, Kitayama ＆ Repin 2002)、異なる地質条件における生産性の標高による変化(Kitayama ＆ Aiba 2002)などである。
