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...

The relationship between biomass distribution and allometric growth is closely related to formation of plant ecological strategies, it is of great significance to understand adaptability of a plant to environment and to reveal mechanism of invasive plants invading a region. At present, not much has ...

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...

Human activity has greatly increased the amount of biologically available nitrogen entering the natural environment. Addition of N can affect growth of and competitive interactions between native and invasive plants, thus increasing or decreasing the risk of invasion by alien species. Bidens...

Bidens frondosa L. populations are studied in the Republic of Mordovia. The density of individuals of invasive species is high and it fluctuates on average from 78 to 202 individuals per 1 m². A comparison of the seed mass, the number of seeds per calathidium, the seed germination, and the area of...

Bidens frondosa L. is an exotic annual herb native to North America, which often co-occurs with native congener B. tripartita L. in habitats, such as abandoned arable land, farmland etc. In order to understand the invasiveness of B. frondosa, the effects of compound fertilizer on competitive...

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...
