Summary: Assessing the effects of plant-host shift is crucial for monitoring insect populations and intervention in conservation and pest management. A single-species two-patch model is proposed to study the movement pattern and viability of an insect that exhibits density-dependent dispersal. The model is validated using laboratory experiments and applied to Drosophila suzukii, showing that a shift in fruit host choice can significantly impact the growth and persistence of the species.

Summary: The study revealed that Praxelis clematidea in China exhibits autonomous apomixis as its reproductive mode, allowing seed production without the need for pollen. This characteristic significantly enhances the species' potential for successful colonization and dispersal into new areas, contributing to its high invasion potential. Effective control measures should be implemented to prevent autonomous (pollen-independent) seed production.

Summary: This study investigated the ecological recovery following the management of Salvinia molesta in South Africa. The presence of S. molesta negatively impacted the food web structure, but after mechanical or biological control, there was an improvement in the food chain structure.

Summary: Climate warming has direct and indirect impacts on plant invasion success. However, the effects of rising temperatures and plant density on invasive alien aquatic species remain largely unknown. A microcosm experiment revealed that temperature, plant density and neighbor identity influenced the traits and growth of the invasive species, and rising temperature could enhance competition or facilitation among these species.

Summary: Aquatic invasive plants can have significant impacts on ecology and economy, making effective management essential. However, there is limited research on recreational user engagement in biological control, and existing studies have given little emphasis on important predictors from outdoor studies. This study explores the factors influencing recreational users' willingness to participate in controlling aquatic invasive plants, and finds that recreational factors, knowledge of invasive plants, and participation in water-based activities are significant incentives to engage.

Summary: This study demonstrates that invasive plant Ambrosia artemisiifolia adapts its seed traits in response to climate variations along latitudes and longitudes. Germination time is delayed with increasing latitude and longitude, while germination rate shows a reversed pattern. Temperature is identified as the dominant driver of the variability in seed traits and germination.

Summary: The increased global flow of humans and trade has heightened the risk of invasion by exotic alien plants. Investigating the colonizing ability of invasive alien organisms in local areas is important for developing prevention and control measures. Model predictions regarding the spread of Flaveria bidentis to southern China have been controversial.

Summary: This review presents the current research status of allelopathic algal inhibition by aquatic plants, listing common aquatic plant species and allelochemicals. It discusses the inhibition mechanism of allelochemicals on algae and summarizes key factors affecting allelopathic inhibition, such as pH, temperature, algal cell density, and allelochemical concentration. The present utilization modes of allelochemicals on algae are also presented. The article highlights existing problems in the study and proposes suggestions for further research.

Summary: This study constructed microcosms to simulate the decomposition processes of aquatic plant residues and invasive algae, finding that the addition of algae promoted the decomposition and produced a positive co-metabolism effect. The response of plant residues to algal organic matter differed, with P. australis showing the highest co-metabolism intensity. As shallow lakes face the double pressure of eutrophication and global warming, the co-metabolism effect of residue decomposition processes should be considered in future lake management.

Summary: The study investigated the composition, dynamics, and co-occurrence patterns of bacteria and fungi in the phyllosphere of the invasive aquatic plant Alternanthera philoxeroides. The study revealed significant associations between the community composition of attached microbes and plant stoichiometry, substrate composition, and extracellular enzyme activity. Deterministic processes played a predominant role in the assembly of attached bacteria, while stochasticity was the major driver for attached fungal assembly. The study provides important insights into the microbes and their interactions in the phyllosphere of A. philoxeroides, a key invasive species under national management and control.

Summary: This study aimed to estimate the allelopathic intensity of four Asteraceae invasive plant species and investigate the effect of silver nanoparticles on their allelopathy. The results showed that silver nanoparticles intensify the allelopathic intensity of these invasive plants, particularly Bidens pilosa. This study is of significant importance for understanding the ecological impact of invasive plants.

Summary: In this study, the effects of nutrient enrichment, salinity, and their interaction on the competitive interactions between a native macrophyte (wild celery) and a nonindigenous invasive macrophyte (hydrilla) were experimentally examined. The results showed that fertilizer enhanced wild celery's leaf area and aboveground biomass, but did not enhance hydrilla's competitiveness. Salinity negatively affected wild celery's leaf area and biomass, and also reduced hydrilla's belowground biomass production, but did not influence competition.
