Clonal integration affects growth, photosynthetic efficiency and biomass allocation, but not the competitive ability, of the alien invasive Alternanthera philoxeroides under severe stress.
BACKGROUND AND AIMS Many notorious alien invasive plants are clonal, but little is known about some roles and aspects of clonal integration. Here, the hypothesis is tested that clonal integration… Expand
United we stand, divided we fall: a meta-analysis of experiments on clonal integration and its relationship to invasiveness
Many ecosystems are dominated by clonal plants. Among the most distinctive characteristics of clonal plants is their potential for clonal integration (i.e. the translocation of resources between… Expand

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… Expand
Effects of soil nutrient heterogeneity on intraspecific competition in the invasive, clonal plant Alternanthera philoxeroides.
BACKGROUND AND AIMS Fine-scale, spatial heterogeneity in soil nutrient availability can increase the growth of individual plants, the productivity of plant communities and interspecific competition.… Expand
Reciprocal and coincident patchiness of multiple resources differentially affect benefits of clonal integration in two perennial plants
Summary 1. The modules of plants experience different levels of resources, and clonal plants can integrate resource heterogeneity. However, no studies have tested whether the benefits of clonal… Expand
Invasive clonal plant species have a greater root-foraging plasticity than non-invasive ones
Clonality is frequently positively correlated with plant invasiveness, but which aspects of clonality make some clonal species more invasive than others is not known. Due to their spreading growth… Expand
Burial Depth and Stolon Internode Length Independently Affect Survival of Small Clonal Fragments
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… Expand
Does mechanical disturbance affect the performance and species composition of submerged macrophyte communities?
Submerged macrophyte communities are frequently subjected to disturbance of various frequency and strength. However, there is still little experimental evidence on how mechanical disturbance affects… Expand
Adaptation of rhizome connections in drylands: increasing tolerance of clones to wind erosion.
BACKGROUND AND AIMS Wind erosion is a severe stress for plants in drylands, but the mechanisms by which plants withstand erosion remain largely unknown. Here, the hypothesis is tested that… Expand
A trade-off between guerrilla and phalanx growth forms in Leymus secalinus under different nutrient supplies.
BACKGROUND AND AIMS A phalanx growth form enables clonal plants to make better use of resource-rich patches, whereas a guerrilla growth form provides them with opportunities to escape from… Expand
