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

open access: yesEcol 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.

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

open access: yesNew 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]

open access: yesEcol 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 <i>Salvia daiguii</i>, an endemic species from Hunan, China. [PDF]

open access: yesEcol 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.

Comprehensive Environmental Flows Assessment for Multi‐Guilds in the Riparian Habitats of the Yangtze River

open access: yesWater Resources Research, Volume 58, Issue 9, September 2022., 2022
Abstract The development of new strategies for the operation of existing dams is essential for restoring ecosystems that have already been affected by the construction and current regulation of these dams. The assessment of environmental flows (EFs) is significant in guiding such strategic dam operations.

Remotely piloted aircraft systems remote sensing can effectively retrieve ecosystem traits of alpine grasslands on the Tibetan Plateau at a landscape scale

open access: yesRemote Sensing in Ecology and Conservation, Volume 7, Issue 3, Page 382-396, September 2021., 2021
Remotely piloted aircraft systems visible remote sensing can effectively monitor ecosystem traits of alpine grassland at landscape scale. It also works efficiently in ecosystem traits retrieving and high‐resolution mapping, and helps us understand the response of these ecosystems to global changes at a scale beyond one site. Abstract Ecosystem trait is
