Bidens frondosa is a new invasive species in China. However, the mechanisms underlying its invasiveness are still not understood. This study compared the new invader with its invasive congener, Bidens pilosa, and two native congeners, Bidens biternata and Bidens tripartita, in terms of their...

In laboratory studies, we determined the allelopathic potential of sweet potato (Ipomoea batatas L. (Lam.)) varieties and identified their putative allelochemicals using gas chromatography mass spectrometer (GC-MS). The allelopathic potential of sweet potato varieties was determined to control...

The role of the most common land iguana (Conolophus subcristatus) in the Galápagos Islands as an effective seed disperser is explored in this study. A total of 5705 seeds of 32 plant species were identified from 160 scats, 4545 of which (80%) appeared visually undamaged. Germination trials of 849...

The invasive plant Bidens pilosa has caused losses to agriculture and livestock. We studied the effects of B. pilosa on rhizosphere soil microorganisms and soil nutrients of different native species. The soil microbial species were examined using phospholipid fatty acid (PLFA), and the...

Berberine significantly inhibited the root growth of several invasive weeds [Bidens pilosa L., Mikania micrantha Kunth, Conyza bonariensis (L.) Cronq., Pistia stratiotes L., Alternanthera philoxeroides Griseb and the plant Arabidopsis thaliana]. The IC50 value of berberine after 7-days, on the...

In recent years, the response of fern gametophytes to environment has raised much attention. However, studies on the influence of plant invasion to fern gametophytes are scarce. Allelopathy plays an important role in biological invasion. Hence, it is necessary to study the allelopathic effects of...

According to the field survey of alien invasive plants of Jinziling, there were 23 kinds of alien invasive plants in the scenic spot. Species with the comprehensive dominance degree higher than 10% were as follows: six kinds of Asteraceae: Bidens pilosa, Aster subulatus, Ageratum conyzoides, ...

To examine the difference in photosynthetic traits and resource capture and use efficiency between three exotic plants (Eupatorium adenophorum Spreng, Alternanthera philoxeroides L. and Bidens pilosa L.) and three native plants (Picris divaricata Vaniot., Setaria plicata (Lam.) T. Cooke and Verbena ...

Parthenium hysterophorus L. and Bidens pilosa L., two species of Asteraceae, are recently recorded for the first time in the United Arab Emirates (UAE). This information is based on our recent field work and critical evaluation of the existing literature. P. hysterophorus is a highly invasive alien ...

Previously we found that soil in the late-successional-stage forest exerted the strongest allelopathic effects on invasive plants and soil in this forest had the highest concentration of abscisic acid (ABA). Therefore, we hypothesize that ABA may function as the "chemical shields" of forest...
