The effect of Elymus nutans sowing density on soil reinforcement and slope stabilization properties of vegetation-concrete structures.

Elymus nutans is an herbaceous plant that can be used to restore degraded alpine and subalpine ecosystems. Here, we evaluated how sowing density affects soil reinforcement and slope stabilization properties of vegetation-concrete structures. To investigate the optimal sowing density of E.

Spatiotemporal photosynthetic physiology responses of remnant populations to regulated water level fluctuations.

The construction of the Three Gorges-Gezhouba Dam cascade hydropower station has changed the water level fluctuation pattern of the habitats for remnant rare and endangered populations downstream of the dam. The present study utilized biochemical markers of photosynthetic physiology to evaluate the spatiotemporal responses of remnant populations to human-regulated water level fluctuations. The results showed that the photosynthetic physiological activities of remnant populations underwent a period of rapid growth, followed by a gradual decline in the growth recovery phase after flooding.

Thalli Growth, Propagule Survival, and Integrated Physiological Response to Nitrogen Stress of var. in Shennongjia Mountain (China).

In this study, effects of nitrogen (N) availability on growth, survival of var. , and whether it respond nitrogen stress in an integrated physiological way was evaluated. Thalli growth and propagule survival, thalli N and phosphorus (P) content, and activity of phosphomonoesterase (PME) of var.

Effects of the seasonal flooding on riparian soil seed bank in the Three Gorges Reservoir Region: a case study in Shanmu River.

Introduction: The water-level fluctuation in the Three Gorges Reservoir Region has changed dramatically as a result of the hydroelectric project for flood control and power generation. The riparian seasonal hydrological environment also has changed from summer flooding with winter drought to summer drought with winter flooding. The changes of riparian seed bank and vegetation were investigated to determine the effects of the seasonal flooding on the composition and spatial distribution of riparian soil seed bank and the similarity of seed bank to standing vegetation.
