Aims: Exotic plant invasions are important components of global change, threatening both the stability and function of invaded ecosystems. Shifts in competitive ability of invasive plants versus their native congeners have been documented. Enhanced UV-B radiation and nitrogen (N) deposition might...

Weedy sunflower has become a problem worldwide, giving significant yield losses in sunflower and soybean fields even at low densities, decreasing their oil quality and allowing gene flow among crops and weeds. Its evolution differs among countries due to availability of wild forms. The problem is...

Xanthium spinosum is a noxious invasive weed that is spreading throughout Xinjiang Province. This plant threatens ecological safety, biodiversity, and agricultural development in affected areas. Because X. spinosum has shown strong adaptation to the divergent environment in the Hi River valley,...

To explore the effect of Galinsoga parviflora Cav., an invasive plant on seedling growth and photosynthetic physiological characteristics of broad bean (Vicia faba L.), the pot experiments were conducted to study the effects of plant heights, leaf areas, biomass, chlorophyll contents, chlorophyll...

Caesalpinia pulcherrima is an exotic species belongs to the Fabaceae family commonly known as flamboyant-mirim, and widely used for urban forestry. This study aimed to evaluate the effect of different substrates on the emergence and early seedlings growth of C. pulcherrima. The experiment was...

We conducted laboratory bioassay and pot experiments to find the difference in the allelopathic potentials of aqueous root leachates from 4-dominant tree species (Quercus acutissima Carruth., Robinia pseudoacacia L., Pinus thunbergii Parl. and Amorpha fruticosa L.) on seed germination and seedling...

This study aimed to examine the allelopathic potential of Eucalyptus and Calotropis species on seed germination and seedling growth of Acacia ehrenbergiana (Hayne), Acacia gerrardii (Benth.) and Acacia tortilis (Forssk.). The aqueous leaf extracts of Eucalyptus camaldulensis var. obtusa (Blakely), ...

Although carbon (C) additions to soil have been used in restoration to combat invasive species through changes in soil nitrogen (N) availability, carbon amendments to soil derived from plant material can impact soil N availability in a species-specific manner. As such, amendment-driven feedbacks on ...

Background and Purpose: Aster lanceolatus Willd. is a highly invasive plant in Serbia. However, mechanisms that allow A. lanceolatus to be so competitive and to become dominant in riverine plant communities are not clear. Several potentially allelopathic compounds have been identified in A....

Potentially invasive species can be identified before they start to spread by comparing their traits with those of successful invaders. A powerful tool for delimiting the traits associated with invasiveness are analyses of a number of species of the same genus, where it is more likely to detect...
