“…These high CO 2 emissions related to high microbial activity with high plant biomass [31]. In this study, the biomass of Phragmites was the highest, compared with those of Sphagnum and sedge [15] (Supplemental Table 2). Root exudates are an important source of labile organic matter for soil microbial communities and are released at greater rates during the growing season than when the plants are dormant [32].…”

“…This result might be an exceptional case of inhabitation of a Sphagnum in this site. Most distributions of Sphagnum were observed at tussock structures as microtopography by sedges and grasses within a wetland (74 %) and the shaded slope area under Pinus densiflora's canopy in wetland boundary (26 %) [15]. Plant productivity such as emergent vegetation is generally the largest C flux into ecosystems, and any alteration thereof could drive changes in ecosystem C storage [37].…”

Microbial Community and Greenhouse Gas Fluxes from Abandoned Rice Paddies with Different Vegetation

The area of rice paddy fields has declined continuously in East Asian countries due to abandonment of agriculture and concurrent socioeconomic changes. When they are abandoned, rice paddy fields generally transform into wetlands by natural succession. While previous studies have mainly focused on vegetation shifts in abandoned rice paddies, little information is available about how these changes may affect their contribution to wetland functions. As newly abandoned fields proceed through succession, their hydrology and plant communities often change. Moreover, the relationships between these changes, soil microbial characteristics, and emissions of greenhouse gasses are poorly understood. In this study, we examined changes over the course of secondary succession of abandoned rice paddies to wetlands and investigated their ecological functions through changes in greenhouse gas fluxes and microbial characteristics. We collected gas and soil samples in summer and winter from areas dominated by Cyperaceae, Phragmites, and Sphagnum in each site. We found that CO2 emissions in summer were significantly higher than those in winter, but CH4 and N2O emission fluxes were consistently at very low levels and were similar among seasons and locations, due to their low nutrient conditions. These results suggest that microbial activity and abundance increased in summer. Greenhouse gas flux, soil properties, and microbial abundance were not affected by plant species, although the microbial community composition was changed by plant species. This information adds to our basic understanding of the contribution of wetlands that are transformed from abandoned rice paddy systems.

“…Mean values of daily mean temperature and monthly precipitation of the study site from 2011 to 2018 were ranged from about − 2°C (January) to about 27°C (August) and from about 13 mm (January) to about 380 mm (July), respectively (Additional file 1: Figure S1). The wetland is a typical APTs consisting of seven wetland units (Hong and Kim 2013a). Inflow water from the watershed of the study site was the major water source and precipitation was the minor one (Hong and Kim 2013a).…”

Changes in vegetation and flora of abandoned paddy terraces in responses to drawdown

In order to assess the impacts of drawdown for land-use change on a Sphagnum-marsh, we compared the vegetation and flora of the wetland before and after the drawdown with focusing on the population of Sphagnum palustre L. Remarkable changes in the coverage of S. palustre and the major vegetational components of the wetland were observed. The coverage of S. palustre markedly decreased by about 75% (from approx. 247 m 2 in 2011 to approx. 62 m 2 in 2015) after the drawdown. Tree species such as Salix spp. extended (from about 70% to about 83% in the total coverage of the wetland), whereas herbaceous species shrunk after the drawdown. Uplandinhabiting species such as obligate plants for uplands (OBU) increased, whereas wetland-inhabiting species such as facultative plants for wetlands (FACW) and OBW decreased in terms of vegetational coverage. The total number of plant species decreased from 70 species to 62 species after the drawdown, including the disappearance of some wetland-inhabiting species from the wetland. We suggest that the attention for further studies on the abandoned paddy terraces (APTs) and effort for the management and conservation of APTs and APT-inhabiting species that are vulnerable to human-induced disturbances have to be paid more.

The purpose of this study is to reveal the effect of plant life cycle to plant settlement by 1 year monitoring. The subjects of monitoring are the plants (3 plant life cycle, 9 taxa) well established in the mesocosm. 18 mesocosms were divided into 3 sets and water levels were maintained at 0, 20 and 60 cm during 16 weeks from mid-May, respectively and at 0 cm except these 16 weeks. Height and population size of transplanted perennial plants (Scirpus tabernaemontani, Zizania caduciflora, Typha (Typha angustifolia and Typha orientalis)) at 1st year were not affected by diverse water level, though any more seedlings of these species were not settled at this condition. In contrast, water level condition strong influenced annual and biennial plant, relatively. As a result, timing and duration of flooding have great effect on successful settlement of annual and biennial plant without rhizome.
