    Although ecosystem degradation is often caused by existing slopes vegetated with commercial species, limited data are available for implementing practical approaches for nature restoration by transplanting native species to those vegetated slopes. Existing vegetated slopes are characterized by spatial heterogeneity in the habitat environment and competition with existing vegetation, which affect the behaviors of transplanted native species. In this study, we examined the factors affecting the survival, growth, verticillation, and flowering of Lilium pensylvanicum, a native coastal-meadow species transplanted to a vegetated road slope in Hokkaido, Japan. In the fourth year after transplantation, the number of surviving plantlets was 364 (57% of 640 transplanted plantlets) and the number of plantlets that shifted to verticillate leaves was 181 (50% of the survivors). The flowering plantlets accounted for 9% (n = 34) of the survivors. The generalized linear model showed that plantlet survival is strongly promoted by a larger bulb scale, that is, nutrient reserves. Furthermore, the survival ratio was greatly improved in the drought-prone, stressful habitats with low vegetation coverage, even for plantlets with relatively smaller bulb scales. However, in the moist habitat with high coverage, the survival ratio was greatly decreased regardless of the bulb scale size. Growth, verticillation, and flowering were facilitated by higher soil nutrient availability, such as a lower C/N ratio and thicker soil layer. Therefore, transplanting of native species to vegetated slopes requires the selection of stress-tolerant species with large nutrient reserves and identification of optimal habitats for transplanting, namely stressful environments with reduced vegetation coverage.

  • Root respiratory costs of ion uptake, root growth, and root maintenance in wetland plants: efficiency and strategy of O2 use for adaptation to hypoxia Reviewed International journal

    Oxygen use in roots is an important aspect of wetland plant ecophysiology, and it depends on the respiratory costs of three major processes: ion uptake, root growth, and root maintenance. However, O2 allocation in wetland plants has received little attention. This study aimed to determine the O2 allocation and specific respiratory cost of each process under hypoxic conditions, to better understand the strategy and efficiency of O2 use in wetland plants. The root respiration rate, nitrogen uptake, and root growth in three Carex species with different growth rates were examined under hypoxic conditions using different N sources, and the respiratory costs of ion uptake, root growth, and root maintenance were statistically estimated. All species exhibited low specific costs and low ratios of O2 allocation for root growth (2.0 ± 0.4 mmol O2 g–1 and 15.2 ± 2.7%, respectively). The specific cost of ion uptake was 20–30% lower in fast-growing species than in slow-growing species. As plant growth rate increased, the O2 allocation ratio for ion uptake increased, and that for root maintenance decreased. The cost was higher when NO3– was fed, than when NH4+ was fed, although the pattern of O2 allocation ratios for three processes was similar for NO3– and NH4+. Our results indicate that wetland plants primarily employ an O2 use strategy of minimising the respiratory costs of root growth, and fast-growing plants specifically use O2 to maximise ion uptake. These findings provide new insights into ecophysiological behaviours of roots in adaptation to hypoxia.

  • Phytometric assessment of alder seedling establishment in fen and bog: Implications for forest expansion mechanisms in mire ecosystems Reviewed

    Aims Rapid forest expansion as a result of anthropogenic activities has been observed in many mires. However, it is unclear which environmental factors are driving this expansion because there have been no systematic investigations into mire-specific tree seedling establishment. This study investigated factors affecting the establishment of common alder (Alnus japonica) in a mire.
    Methods We performed seed sowing and seedling transplantation field experiments to examine the factors influencing germination rate, seedling survival, and seedling growth of A. japonica.
    Results Germination rate and seedling survival period decreased with increasing water level, and seedling dry weight was reduced at pH < 6.0. Germination rate was also lower in the fen, whereas seedling dry weight was lower in the bog, which could be reasonably explained by the higher water level in the fen and the lower pH in the bog.
    Conclusions Our results showed that germination and seedling growth in the fen and bog were each inhibited by different mire-specific conditions: high water level and low pH, respectively. Therefore, seedling establishment could be improved by either lowering the water level in fens, to increase germination rate and survival, or raising the pH in bogs, to increase growth.

  • Functional linkage between N acquisition strategies and aeration capacities of hydrophytes for efficient oxygen consumption in roots Reviewed

    We evaluated the specific strategies of hydrophytes for root O2 consumption in relation to N acquisition and investigated whether the strategies varied depending on the aeration capacity. Aeration capacity of roots is an important factor for determining hypoxia tolerance in plants. However, some hydrophytes possessing quite different aeration capacities often co-occur in wetlands, suggesting that root O2 consumption also strongly affects hypoxia tolerance. We cultivated Phragmites australis with high aeration capacity and Zizania latifolia with low aeration capacity in hypoxic conditions with NH4+ or NO3– treatment and compared the growth, N uptake, N assimilation, and root respiration between the 2 species. In Z. latifolia grown with NH4+ treatment, high N uptake activity and restrained root growth led to sufficient N acquisition and decrease in whole-root respiration rate. These characteristics consequently compensated for the low aeration capacity. In contrast, in P. australis, low N uptake activity was compensated by active root growth, but the whole-root respiration rate was high. This high root respiration rate was allowed by the high aeration capacity. The O2 consumption-related traits of hydrophyte roots were closely correlated with N acquisition strategies, which consequently led to a compensational relationship with the root aeration capacity. It is likely that this functional linkage plays an important role as a core mechanism in the adaptation of plants to hypoxic soils.

    ハンノキの定着と成長に関わる環境条件について、現地での播種・植栽実験を通じて検証を行うことを目的とした。ハンノキが急増した釧路湿原南部を調査試験地とし、ハンノキ種子の播種とハンノキ稚樹の植栽を行い、それらの生育反応と環境要因との対応関係について解析を行った。ハンノキの種子発芽率や植栽値樹の生残率は地下水位と負の相関関係にあり、植栽稚樹の成長量は土壌水pHと正の相関関係にあることが示された。ハンノキ林の発達には、冠水しにくい(低水位)環境と、強酸性ではない環境の両条件を満たす立地が必要であることが明らかとなった。

    δ15N variations within foliage and relating ecophysiological factors in tropical evergreen tree, Combretocarpus rotundatus, were studied focusing on leaf positions, leaf nitrogen status and habitats.
    In Mud swamp and Peat swamp, the three leaves were collected at each of the nine positions consisted of three leaf positions within a branch (apical to basal) x three branch positions in a tree (higher to lower), respectively, and nitrogen concentration and stable nitrogen isotope were examined.
    Whole variation in leaf δ15N was firstly affected by the difference of habitat, secondly by branch position and thirdly by leaf position. In Mud swamp, the mean δ15N was 3.5‰ higher than Peat swamp, which reflects the difference of nitrogen source positively correlating to soil decomposition traits. In each habitat, the δ15N variation reached 3‰, and the higher values were obtained from apical leaves in higher branch. Moreover, leaf nitrogen concentration was positively correlated with the δ15N. Consequently, the isotope fractionation synchronized with photosynthesis would be closely concerned with the foliage δ15N pattern.
    This study indicated that δ15N variations within foliage would not be negligible factor to evaluate the plant δ15N value, and those variations would depend on physiological activities varying along branch position and leaf position.
