Introduction
I focus on several research areas including (1) Transgenerational effects in clonal plants: ecological and evolutionary consequences of transgenerational life-history traits that are related to environmental factors such as herbivory, physical disturbance and availability of resources; (2) Invasive plant ecology: roles of clonal life-history traits in plant invasion; (3) Plant-insect interactions: roles of generalist and specialist herbivores in plant invasion.

Article
Plants have evolved a variety of defense traits against foliar herbivory, including the production of primary and secondary metabolites, the allocation of chemical compounds, and morphological plasticity. Using two vegetative generations of the invasive clonal species Alternanthera philoxeroides, we investigated the effects of maternal and offsprin...
Article
Full-text available
The ability to tolerate novel herbivores is widely considered to influence plant invasion success. For clonal plants that have reduced capacity to evolve in response to novel herbivores, legacy effects of herbivory on parental plants might be translated to offspring ramets, resulting in pre-adaptation to tolerate herbivory for new vegetative growth...
Article
Epigenetic changes and maternal effects, collectively termed transgenerational effects, allow responses of organisms to environmental factors to be passed between generations. This is well-known in the case of sexual reproduction but little studied in asexual reproduction, which is often the primary mode of reproduction in clonal plants. To test fo...
Article
Full-text available
Purpose Benefits of clonal integration have been widely documented in clonal species, but quantitative tests of the translocation of resources in both directions between older and younger ramets (e.g., transport rate and partitioning pattern) are still scarce. Methods A control experiment, using a clonal species Alternanthera philoxeroides as plan...
Preprint
Interactions between alien plants and the newly emerging enemies in introduced ranges may determine plant invasion success. However, little is known about whether herbivory-induced responses are transmitted across vegetative generations of plants, and whether epigenetic changes are involved during this process. In a greenhouse experiment, we examin...
Article
Aims Phenotypic plasticity enables plants to buffer against environmental stresses and match their phenotypes to local conditions. However, consistent conclusive evidence for adaptive plasticity has only been obtained for a few traits. More studies on a wider variety of plant functional traits and environmental factors are still needed to further u...
Article
Full-text available
Aims: Invasive plants are a major threat to biodiversity and may adversely affect food security. Clonal integration enables the sharing of resources between connected ramets and can enhance plant performance in many invasive species. However, few studies have examined the role of clonal integration when weeds are exposed to plant growth regulators...
Article
Aims Recent studies have revealed heritable phenotypic plasticity through vegetative generations. In this sense, changes in gene regulation induced by the environment, such as DNA methylation (i.e. epigenetic changes), can result in reversible plastic responses being transferred to the offspring generations. This trans-generational plasticity is ex...
Article
• High-biodiversity communities have been shown to better resist plant invasions through complementarity effects. Species richness (SR) is a widely used biodiversity metric but lacks explanatory power when there are only a few species. Communities with low SR can have a wide variety of phylogenetic diversities (PD), which might allow for a better p...
Article
Spatial heterogeneity of soil nutrients and earthworm activity can each increase the performance of plant species, but their interactive effects have been little studied. The ability of plants to forage for nutrients by concentrating roots where nutrients are concentrated can partly explain the positive effects of nutrient heterogeneity, but whethe...
Article
Biological invasions are determined by interactions between resident plant communities and exotic plants. Time of invasion and species diversity of resident plant communities may greatly affect exotic plant invasions. We assembled low‐ and high‐diversity resident plant communities by sowing seeds of four and eight grassland species, respectively, a...
Article
Environments experienced by parent ramets of clonal plants can potentially influence fitness of clonal offspring ramets. Such clonal parental effects may result from heritable epigenetic changes such as DNA methylation, which can be removed by application of DNA de‐methylation agents such as 5‐azacytidine. ● To test whether parental shading effects...
Article
Tolerance to herbivory influences the success of invasive species in introduced ranges, and thus a comparison of the difference in herbivory tolerance between invasive and native species may help to understand the mechanisms of plant invasions. We conducted a greenhouse experiment in Beijing, China to examine effects of aboveground herbivory (by a...
Article
A worth noticing pattern in current invasive biology is the clonal ability of many of the world's worst invasive plants. Selective placement of ramets (i.e. foraging behavior) can intensify ramet performance and allocation, and place more ramets in the more favorable microhabitats, which can maximum utilize resource and share risk in heterogeneous...
Article
Aims The plant-herbivore interaction is one of the most fundamental interactions in nature. Plants are sessile organisms, and consequently rely on particular strategies to avoid or reduce the negative impact of herbivory. Here, we aimed to determine the defense strategies against insect her-bivores in the creeping invasive plant Alternanthera philo...
Article
Clonal integration, i.e., resource sharing between interconnected ramets, can help clonal plants tolerate abiotic stress. However, few studies have directly examined the ecological significance of clonal integration in the ability of clonal plants to tolerate biotic stress such as herbivory. We grew clonal fragments of an invasive clonal plant Alte...
Article
Full-text available
Parental environments may potentially affect offspring fitness, and the expression of such parental effects may depend on offspring environments and on whether one considers an individual offspring or all offspring of a parent. Using a well-studied clonal herb, Alternanthera philoxeroides, we first grew parent plants in high and low soil-nutrient c...
Article
Biodiversity commonly plays important roles in ecosystem functioning. While many studies have tested effects of species diversity on productivity, carbon and nitrogen cycling and resistance to biological invasion, few have examined how diversity of submerged macrophytes affects the water quality of aquatic ecosystems. We assembled aquatic microcosm...
Article
Responses to both submergence and de-submergence are important for evaluating flood tolerance of plants. Clonal integration (resource translocation between connected ramets within clones) has been shown to increase flood tolerance of amphibious clonal plants. However, no study has truly separated the effects of clonal integration during de-submerge...
Article
Repeated exposure to submergence and de-submergence may induce acclimation in plants growing in riparian areas. However, the effect of each consecutive submergence and de-submergence event has not been evaluated separately. We subjected a riparian species Alternanthera philoxeroides to two different fluctuation frequencies: low fluctuation frequenc...
Article
Full-text available
The evolution of phenotypic plasticity of plant traits may be constrained by costs and limits. However, the precise constraints are still unclear for many traits under different ecological contexts. In a greenhouse experiment, we grew ramets of 12 genotypes of a clonal plant Hydrocotyle vulgaris under the control (full light and no flood), shade, a...
Article
Aims Clonal integration can increase performance of clonal plants suffering from environmental stress, and clonal plants in many wetlands commonly face stress of flooding accompanied by salinity. However, few studies have tested roles of clonal integration in amphibious plants expanding from terrestrial to aquatic saline habitats. Methods Basal (ol...
Article
Full-text available
Background and aimsFine-scale spatial heterogeneity of soil nutrients often increases growth of plants, especially clonal species. Herbivory could change this positive effect of soil heterogeneity. Furthermore, detritivory may alter soil heterogeneity and indirectly modify herbivory. However, little is known about the interactive effects of soil nu...
Article
 What confers invasive alien plants a competitive advantage over native plants remains open to debate. Many of the world’s worst invasive alien plants are clonal and able to share resources within clones (clonal integration), particularly in heterogeneous environments. Here, we tested the hypothesis that clonal integration benefits invasive clonal...
Article
Defoliation by herbivores commonly imposes negative effects on plants, and physiological integration (resource sharing) can enhance the ability of guerilla clonal plants to tolerate stresses. Here we examined whether physiological integration can increase the ability of phalanx clonal plants to withstand defoliation. On a high mountain grassland in...

Full-text available
To restore deteriorated lake ecosystems, it is important to identify environmental factors that influence submerged macrophyte communities. While sediment is a critical environmental factor for submerged macrophytes and many studies have examined effects of sediment type on the growth of individual submerged macrophytes, very few have tested how se...
Article
Full-text available
Nutrients may affect the invasiveness of alien plants and the invasibility of native plant communities. We performed a greenhouse experiment to investigate the interactive effect of invasion by a clonal herb Hydrocotyle vulgaris and nutrient enrichment on biomass and evenness of native plant communities. We established three types of plant communit...
Article
Some clonal plants can spread their ramet populations radially, and soil heterogeneity and clonal integration may greatly affect the establishment of these types of populations. We constructed Alternanthera philoxeroides populations with a radial ramet aggregation, allowing old ramets of clonal fragments to concentrate in central pots and younger r...
Article
Full-text available
Aims Clonal plant species have the potential for high relative performance in heterogeneous environments, and this might increase the competitive ability and invasiveness of introduced clonal plant species. It was hypothesized that clonal species whose performance responds more to heterogeneity of a resource have higher competitive ability in habit...
Article
Full-text available
Biological invasions can have strong negative impacts on native biodiversity and ecosystem functions. Water level and nitrogen deposition are important factors that can affect plant invasions in wetlands. Hydrocotyle vulgaris of the Apiaceae family is a perennial herb introduced to China that can be established and multiplied rapidly in a variety o...
Article
Full-text available
Physiological integration between connected ramets can increase the performance of clonal plants when ramets experience contrasting levels of resource availabilities in heterogeneous environments. It has generally been shown or assumed that clonal integration has little effect on clonal performance in homogeneous environments. However, a conceptual...
Article
Full-text available
We conducted a greenhouse experiment to test how clonal integration affected the growth responses of Spartina anglica to light intensity heterogeneity in light availability and whether such effects depended on contrast light intensity. The experiment had three homogeneous treatments and two heterogeneous treatments. In the homogeneous treatments, b...
Article
Full-text available
Some introduced clonal plants spread mainly by vegetative (clonal) propagules due to the absence of sexual reproduction in the introduced range. Propagule pressure (i.e. total number of propagules) may affect the establishment and thus invasion success of introduced clonal plants, and such effects may also depend on habitat conditions. A greenhouse...
Article
Full-text available
Disturbance is common and can fragment clones of plants. Clonal fragmentation may affect the density and growth of ramets so that it could alter intraspecific competition. To test this hypothesis, we grew one (low density), five (medium density) or nine (high density) parent ramets of the floating invasive plant Pistia stratiotes in buckets, and ne...
Article
The presence of algae can greatly reduce the amount of light that reaches submerged macrophytes, but few experimental studies have been conducted to examine the effects of algae on biomass and structure of submerged macrophyte communities. We constructed communities with four submerged macrophytes (Hydrilla verticillata, Egeria densa, Ceratophyllum...
Article
Full-text available
Aims Soil heterogeneity is common in natural habitats. It may trigger foraging responses (placing more ramets and/or roots in nutrient-rich patches than in nutrient-poor patches) and further affect the growth of plants. However, the impact of soil heterogeneity on competitive interactions has been little tested. Methods We conducted a greenhouse e...
Article
Full-text available
Environments are patchy in not only abiotic factors but also biotic ones. Many studies have examined effects of spatial heterogeneity in abiotic factors such as light, water and nutrients on the growth of clonal plants, but few have tested those in biotic factors. We conducted a greenhouse experiment to examine how patchy distributions of competito...
Article
Full-text available
Soil is commonly composed of particles of different sizes, and soil particle size may greatly affect the growth of plants because it affects soil physical and chemical properties. However, no study has tested the effects of soil particle heterogeneity on the growth of clonal plants. We conducted a greenhouse experiment in which individual ramets of...
Article
Full-text available
Spatially heterogeneous distribution of interspecific competitors and intraspecific aggregation of offspring ramets may affect the growth and size structure of clonal plant populations, but these have been rarely studied. We conducted a greenhouse experiment in which we grew a population of eight offspring ramets (plants) of the stoloniferous clona...
Article
Spatial heterogeneity is common in aquatic conditions, but few studies have examined the effects of heterogeneous distributions of biological factors on aquatic plants. Spirogyra (Spirogyra arcta) coexists with many submerged macrophytes, such as Ceratophyllum demersum, but no study has examined the effects of heterogeneous distributions of spirogy...
Article
Full-text available
Environmental heterogeneity is universal and occurs at various spatial scales. Many studies have examined effects of environmental heterogeneity on growth of individual species, but few have tested the effects on species composition and biomass of plant communities, especially those consisting of submerged macrophytes. Moreover, no study has tested...
Article
Full-text available
The capacity of small clonal fragments to survive and grow is a major factor in the spread of clonal plants, especially aquatic species. This study of the introduced, invasive, amphibious, stoloniferous herb Alternanthera philoxeroides in China tested the effects of fragment size, of loss of the stolon apex, and of the original position of a fragme...
Article
Full-text available
Fine-scale, spatial heterogeneity in soil nutrient availability can increase the growth of individual plants, the productivity of plant communities and interspecific competition. If this is due to the ability of plants to concentrate their roots where nutrient levels are high, then nutrient heterogeneity should have little effect on intraspecific c...
Article
Full-text available
Disturbance can fragment plant clones into different sizes and unstabilize soils to different degrees, so that clonal fragments of different sizes can be buried in soils at different depths. As a short-term storage organ, solon internode may help fragmented clones of stoloniferous plants to withstand deeper burial in soils. We address (1) whether b...
Article
Full-text available
Disturbance is common in nature and disturbance-caused fragmentation of clones happens frequently in stoloniferous plants. After fragmentation storage in stolon internodes and leaves may enhance survival and growth of stoloniferous plants. We hypothesize that (1) increasing length of the internode attached to the ramet and (2) presence of leaves wi...
Article
Full-text available
The ability of small clonal fragments to establish and grow after disturbance is an important ecological advantage of clonal growth in plants and a major factor in the invasiveness of some introduced, clonal species. We hypothesized that orientation in the horizontal position (typical for stoloniferous plants) can increase the survival and growth o...
