“…In heterogeneous habitats, the benefits of the division of labor have been extensively investigated in clonal plants (including some invasive plants) (Stuefer, 1998; Pennings and Callaway, 2000; Wang et al, 2008; You et al, 2013; Roiloa et al, 2016; Lin et al, 2018). However, the present study reported the division of labor for an invasive clonal plant in the homogeneous environment, with all basal and apical ramets subjected to the same external resources.…”

Clonal traits can contribute to plant invasiveness, but little is known about the roles of division of labor (a key clonal trait) in homogeneous habitats. The hypothesis tested is that clonal integration allows division of labor and increases the overall performance of an invasive clonal plant, especially under higher soil nutrients. Clonal fragment pairs of aquatic invader Alternanthera philoxeroides (each with four ramets and a stolon apex) were grown in two homogenous habitats with high or low soil nutrient supply, and with stolon connections being either severed (clonal integration prevented) or kept intact (clonal integration allowed). Results showed that stolon connection allowed the division of labor within the clonal fragment, with basal ramets specializing in acquisition of belowground resources and apical ramets specializing in acquisition of aboveground expansion. Moreover, the capacity for division of labor was greater, which brought the clonal fragments of A. philoxeroides stronger clonal propagation and better performance in high nutrient habitats than in low nutrient habitats. The results supported our hypotheses that the developmentally programmed division of labor may facilitate the clonal expansion of this aggressive invader in some homogeneous habitats with high resource availability.

“…A meta‐analysis (Song et al ) suggests that the majority of studies found positive effects of integration on performance of the whole clone. Another study showed that nutrient addition to a subset of the ramets increased the benefits of clonal integration in heterogeneous environments (Lin et al ). Contrary to these two previous studies, our results showed that clonal integration can facilitate the invasion of M. micrantha into plant communities, but it cannot increase growth of the whole clonal system, regardless of the soil nutrient conditions.…”

“…One potential factor that might determine whether clonal integration affects the performance of the donor ramets and the whole clone is resource availability (Alpert ). For example, when developmentally older, proximal ramets of Ipomoea aquatica were grown in favourable terrestrial habitats and developmentally younger, distal ramets were grown in stressful aquatic habitats, nutrient addition to the distal ramets significantly increased the benefits of clonal integration (Lin et al ). In this study, nutrients were added only to the distal ramets but not to the proximal ramets.…”

One benefit of clonal integration is that resource translocation between connected ramets enhances the growth of the ramets grown under stressful conditions, but whether such resource translocation reduces the performance of the ramets grown under favourable conditions has not produced consistent results. In this study, we tested the hypothesis that resource translocation to recipient ramets may reduce the performance of donor ramets when resources are limiting but not when resources are abundant.• We grew Mikania micrantha stolon fragments (each consisting of two ramets, either connected or not connected) under spatially heterogeneous competition conditions such that the developmentally younger, distal ramets were grown in competition with a plant community and the developmentally older, proximal ramets were grown without competition. For half of the stolon fragments, slow-release fertiliser pellets were applied to both the distal and proximal ramets.• Under both the low and increased soil nutrient conditions, the biomass, leaf number and stolon length of the distal ramets were higher, and those of the proximal ramets were lower when the stolon internode was intact than when it was severed. For the whole clone, the biomass, leaf number and stolon length did not differ between the two connection treatments. Connection did not change the biomass of the plant communities competing with distal ramets of M. micrantha.• Although clonal integration may promote the invasion of M. micrantha into plant communities, resource translocation to recipient ramets of M. micrantha will induce a cost to the donor ramets, even when resources are relatively abundant.

“…Studies on the morphological, physiological and ecological characteristics of clonal growth have been systematically compared [9][10][11][12]. In particular, the research has been more focused on the integration and plasticity of clonal plants [13][14], the trade-off between clonal growth and sexual reproduction [15][16], the sharing mechanism of resources [17][18], and characteristics of life history and discussion of cloning diversity [19][20][21]. However, analysis of the spatial expansion strategy and driving force from the perspective of clonal modules were relatively scarce in the extremely arid inland river wetlands with fragile and sensitive ecological systems.…”

The different spatial expansion strategies of clonal plants are the result of their adaptations to extreme heterogeneous environments. In this paper, the spatial expansion strategy and the adaptive responses of Phragmites australis to environmental factors were analyzed by comparing clonal modules along degradation gradients (from wetland ecosystem to desert ecosystem). The results show that: 1) With the deterioration of the environmental conditions, the clonal modules (rhizome internode length, spacer length, primary rhizome length and branch angle) showed a trend of first increasing and then decreasing, but the ramet number showed a trend of decreasing first and then increasing, which turned the survival strategy from "Phalanx" (with cluster distribution and showing the invasion attitude) to "Guerilla" (with discrete distribution and showing the evasive attitude) and then back to Phalanx in the process of space expansion. 2) The clonal modules were significantly different in the heterogeneous environment, and were shown the co-development and trade-off relationships (P<0.05). 3) Soil water content, bulk density, pH value and salinity were the main driving forces-especially soil water content, bulk density and pH values in the middle and deep layers and the soil salinity of each layer were the most important environmental factors. The space expansion strategies of Phragmites australis in an extreme environment complemented the theories of traditional cloning plant ecology. And there was important guiding significance for the management and restoration of the degradation wetlands in arid and semi-arid regions to clarified environmental driving forces of clonal plants in inland river wetlands.
