Cultivated Vegetation Shapes Diversity and Stability of Spontaneous Herbaceous Communities in Residential Green Spaces. [PDF]

Ecol Evol
Cultivated vegetation shapes the diversity and stability of spontaneous herbaceous communities in residential green spaces, with effects varying across vegetation types. Spontaneous communities were dominated by occasional species, and community stability and dissimilarity were more closely associated with species frequency structure than with overall ...

Invasive plants optimize leaf nitrogen allocation in photosynthesis. [PDF]

New Phytol
Summary Invasive plants often outcompete co‐occurring native species by expressing acquisitive functional traits that promote high photosynthetic capacity. However, it remains unclear whether these traits are newly evolved in the introduced (‘away’) range or if invaders arrived preadapted with superior traits from their native (‘home’) range.

On the Limits of Alpine Plants: A Systematic Review of the Factors Behind Species' Elevational Range Limits. [PDF]

Ecol Evol
This systematic review of 107 studies on the factors behind the elevational range limits of alpine vascular plants shows a persistent emphasis on upper limits and abiotic factors, especially temperature, while work at lower limits is more evenly distributed across water availability, plant–plant interactions, and selection/local adaptation.

Endangered status and threatened population ecological factors in Salvia daiguii, an endemic species from Hunan, China. [PDF]

Ecol Evol
Currently, Salvia daiguii is distributed in three populations, with total of about 500 plants and less than 250 mature individuals. Habitat OM and pH are indicators that significantly affect the growth and flowering of S. daiguii. Competition for niche characteristics of dominant plants in the community affects the growth and dispersal of S.

Spatiotemporal Dynamics of Plant–Soil–Enzyme Interactions in Intertidal Wetlands [PDF]

Ecol Evol
This study reveals that during the exposure period in the Shengjin Lake intertidal wetland, the temporal gradient serves as the primary driving force for changes in the plant–soil–enzyme system, followed by alkaline phosphatase activity, nitrate nitrogen, and pH.
