“…Previous studies have shown that G. parviflora contains various aromatic compounds and has antibacterial, antifungal, antioxidant, and antidiabetic pharmacological properties with economic benefits [39,40]. In addition, G. parviflora also has a strong capability to bioaccumulate heavy metals [41,42], which presents a good prospect for the remediation of heavy-metal-contaminated soil. More importantly, G. parviflora is non-toxic and could be used as a food source [9].…”

The Tibetan plateau, with complex and diverse ecosystems, is an important ecological security barrier to China. However, climate change and the spread of invasive plant species have imperiled the once pristine and diverse ecosystem of the region. To prevent the further spread and control of invasive plants, it is important to delineate the potential distribution patterns of alien invasive plants at the regional scale across Tibet and understand their responses to climate change. Galinsoga parviflora Cav., a member of the family Asteraceae, is an annual herbaceous plant distributed globally as an invasive weed and possesses characteristics that make it highly invasive, such as a strong ability to proliferate and disperse. The species is also known to have an allelopathic effect. There has been no report on the spatial distribution of G. parviflora in Tibet. Using field survey data, we investigated the risk of G. parviflora invasion and its impacts on the ecological safety of Tibet. We employed the MaxEnt model using the R language and SPSS software to optimize and select model parameters and data. We acquired various environmental variables along with current and future climate change scenarios (two carbon emission scenarios, SSP126 and SSP585, for the years 2050 and 2090) to predict the geographic distribution and potential risk areas in Tibet that G. parviflora can invade. The MaxEnt model accurately predicted the distribution of G. parviflora in Tibet with an average AUC of 0.985. The most suitable environmental conditions in which G. parviflora performed the best in Tibet included a mean annual temperature of 6.2–10.0 °C and an elevation range of 2672–3744 m above sea level. Our results indicate that low precipitation during the coldest quarter of the year (mean temperature −2–3 °C) was the most important variable predicting G. parviflora distribution. The results also showed that the species was hardly found when precipitation in the coldest quarter exceeded 155 mm. The current potential invasion risk areas for G. parviflora included the river valleys of central, southeastern, and eastern Tibet. With future climate change scenarios (i.e., SSP126, SSP585), the suitable habitats for G. parviflora distribution will likely shift to northwest regions from the southeast. Particularly under the highest carbon emission scenario (i.e., SSP585), the potential risk area expands more rapidly, and the center of distribution shifts to northwest regions. These findings provide useful information about the current and future changes in G. parviflora distribution in Tibet, which is crucial for the comprehensive and proactive management and control of G. parviflora under future climate change.

“…Under heavy metal contaminated soil, it is important to adjust plant heavy metal absorption by changing the external environment, which is important for alleviating the heavy metal stress on the plants [37]. Certain studies showed that adding straws from different crops to soil reduced the heavy metal uptake of plants [37,38]. For hyperaccumulators or accumulators, certain plant straws (such as Youngia erythrocarpa and Cardamine hirsuta) promoted the Cd uptake of the Cd-hyperaccumulator Galinsoga parviflora and the Cd-accumulator Capsella bursa-pastoris, while other plant straws inhibited these properties [8,35,36,[39][40][41].…”

The paddy soils have been contaminated by cadmium (Cd). To remedy the Cd-contaminated paddy soils, four tea types (black, green, white, and dark tea) were added to the Cd-contaminated paddy soils and planted the emergent accumulator plants Nasturtium officinale, and the effects of tea the Cd accumulation of N. officinale were studied. The green, white, and dark tea decreased the biomass of N. officinale, while the black tea had no effects. Compared with the control, the green, white, and dark teas decreased the root biomass by 12.73%, 8.18%, and 17.73%, respectively, and decreased the shoot biomass by 31.50%, 26.43%, and 33.08%, respectively. All four tea types decreased the chlorophyll a, chlorophyll b, and carotenoid contents in N. officinale. For antioxidant enzyme activity, the four tea types decreased N. officinale superoxide dismutase and peroxidase activities, while only the dark tea decreased the catalase activity. The four tea types had no effect on the shoot Cd content in N. officinale, and decreased the shoot Cd extraction due to decreased, or zero effects on the soil exchangeable Cd concentration. Therefore, tea cannot be used to improve the phytoextraction capacity of N. officinale for Cd-contaminated paddy soils.
