Sand burial and precipitation enhancement changed status of tillerous clonal plant Stipa bungeana as dominated species in sandy grassland.
Article in BMC plant biology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSand burial and precipitation drive the community structure and function of semi-arid grassland. Stipa bungeana is a tillerous clonal plant that often forms a community in the sandy grassland, however, it is not clear how sand burial, precipitation enhancement and their interaction on importance of S. bungeana in the plant community. In the semi-arid desertification grassland in northern China, we conducted a two-years field experiment with simulated sand burial (no sand burial, 2 cm and 5 cm sand burial) and precipitation enhancement (ambient precipitation, 1/7 and 2/7 precipitation enhancement) treatments, and the morphological characteristics and important value of S. bungeana were determined.
resultsSand burial and precipitation enhancement promoted the growth of S. bungeana tillers, but reduced the size and aboveground biomass of S. bungeana tuft, thus affecting the status of S. bungeana in the community. Sand burial and precipitation enhancement also significantly reduced plant density and aboveground biomass of all other species except S. bungeana.
conclusionsThese results revealed that S. bungeana may lose its status as the constructive species, due to the accumulation of the negative effects of sand burial. Our findings may be helpful to better understand the process of desertification, and will contribute to grassland management and vegetation restoration in semi-arid desert areas.
