Invasive plants exert significant ecological impacts on native plants, communities, and ecosystems. However, consistent conclusions regarding how traits of invasive plants, native plants, and their divergences affect invasion dynamics are still lacking. Here, we conducted a pairwise common garden experiment to investigate how invasion was influenced not only by invasive plants but also by native plants, aiming to elucidate the role of invasive-plant traits, native-plant traits, and their divergences in invasion processes.

Front Plant Sci

May 2024

Key Laboratory of Resource Biology and Biotechnology in Western China, Ministry of Education, Northwest University, Xi'an, China.

Article Synopsis
  • The study investigates how neighboring plant touch (thigmomorphogenesis) and shading affect the growth of clonal plants, particularly how these factors interact in dense vegetation.
  • It was found that parental ramets (parent plants) exposed to touch in ambient light conditions had offspring with reduced leaf expansion, while the offspring's growth was influenced by the light conditions of both the parent and the offspring's environment.
  • The interaction between parental touch and shading can complicate the growth responses of understory plants, as certain traits like shade avoidance can be influenced positively or negatively depending on the parent's light environment.
