SummaryThe costs and benefits of resource integration in Hydrocotyle bonariensis were examined by comparing severed and intact clones grown across multiple resource gradients. Basipetal movement of water, nitrogen and photosynthates was demonstrated to occur between two rhizome branch systems interconnecting hundreds of ramets within a clone. Hydrocotyle clones of this size and larger have been shown to span highly patchy and unpredictable resource conditions in coastal dune environments. The… 
The effect of local resource availability and clonal integration on ramet functional morphology in Hydrocotyle bonariensis
TLDR
The maintenance of connections between ramets as a Hydrocotyle clone expands allows for resource sharing among widely separated ramets and can result in an integrated morpological response to a resource environment that is patchy in time and space.
Short‐term fitness benefits of physiological integration in the clonal herb Hydrocotyle peduncularis
TLDR
Physiological integration over a gradient in soil moisture resulted in a highly significant net benefit to genet growth that represents a significant enhancement of the average fitness of fragmented genets spanning the moisture gradient relative to the average of those growing in homogeneous moist or dry conditions.
Clonal Plasticity in Response to Reciprocal Patchiness of Light and Nutrients in the Stoloniferous Herb Glechoma longituba L.
TLDR
The results showed that the performance of ramets growing in patches with high light intensity and low soil nutrients into the adjacent opposite patches was increased in terms of fitness-related traits, and that apparent reciprocal resource transport between the ramets in an environment of reciprocal patchiness of resources can enhance the growth ofRamets with complementary resource deficiencies.
Environmental heterogeneity and clonal growth: a study of the capacity for reciprocal translocation in Glechoma hederacea L.
TLDR
It is suggested that predominantly acropetal movement of resources and the pattern of integrated physiological unit formation in G. hederacea are the main properties responsible for the lack of mutual physiological support between connected clonal fragments growing in differing habitat conditions.
Local adaptation within a population of Hydrocotyle bonariensis
TLDR
Small-scale local adaptation may be more likely in clonal plants undergoing little gene flow in spatially heterogeneous environments, including Hydrocotyle bonariensis at high and low elevations of sand dunes on St. George Island, Florida.
Cost-benefits of the clonal integration of Cynodon dactylon,a stolon herbaceous plant,under heterogeneous lighting condition
TLDR
Cynodon dactylon, the stolon herbaceous plant, may take a risk-spreading strategy to reduce the death of genets, which is of vital importance to maintain the fitness of the genets of clonal plants in heterogeneous environments.
Physiological Integration Ameliorates Negative Effects of Drought Stress in the Clonal Herb Fragaria orientalis
TLDR
The net benefit of physiological integration depends on the environment and integration between ramets of F. orientalis could be advantageous only in heterogeneous conditions with a high contrast, and support from a ramet growing in benign patch considerably reduced drought stress and enhanced growth of ramets in dry patches.
Root Foraging Increases Performance of the Clonal Plant Potentilla reptans in Heterogeneous Nutrient Environments
TLDR
The results show that plants of P. reptans adjust their root-foraging intensity according to patch contrast, which indicates an evolutionary benefit of root foraging in heterogeneous environments and no significant evidence that the ability of plastic foraging imposes costs under homogeneous conditions is found.
Nutrient addition does not increase the benefits of clonal integration in an invasive plant spreading from open patches to plant communities.
TLDR
The results do not support the hypothesis that resource translocation to recipient ramets of M. micrantha may reduce the performance of donor ramets when resources are limiting but not when resources have been abundant, and indicate that although clonal integration may promote the invasion ofM.
Differential effects of clonal integration on performance in the stoloniferous herb Duchesnea indica, as growing at two sites with different altitude
TLDR
Clonal integration might help D. indica plants to successfully inhabit the high-altitude habitat of the Qinghai-Tibet plateau and the Sichuan basin of Southwest China, providing new evidences for the notion that clonal integration is an adaptive trait in stressful environments.

Nitrogen translocation in a clonal dune perennial, Hydrocotyle bonariensis
TLDR
Clonal integration of nitrogen, in tandem with a plastic morphology, allow Hydrocotyle clones to expand across a nitrogen-limited dune environment and to locally exploit nitrogen patches when they are encountered.
An analysis of the costs and benefits of physiological integration between ramets in the clonal perennial herb Glechoma hederacea
TLDR
Physiological integration allows clones to maintain a presence in less favourable sites with insignificant cost to ramets in favourable sites, thereby reducing the probability of invasion by other plants, and providing the potential for rapid clonal growth if conditions improve.
Resource sharing among ramets in the clonal herb, Fragaria chiloensis
TLDR
Results suggest that physiological integration of connected rosettes may increase total growth of clones of F. chiloensis through sharing of resources among ramets, especially when resource availability is changeable or patchy.
Influence of physiological integration on survivorship and water relations in a clonal herb
TLDR
A water potential gradient develops within the xylem and facilitates water move- ment between shaded ramets and connected, illuminated ramets, which may moderate the effects of environmental variability on ramet water potential.
Clonal Integration and Population Structure in Perennials: Effects of Severing Rhizome Connections.
TLDR
The results confirm the prediction that integration increases with increasing genet compactness and indicated that destroying physical connections in integrated genets may decrease between-shoot competition rather than between- shoot cooperation.
Physiological integration among ramets of Lathyrus sylvestris L.
TLDR
The existence of carbon transfer among ramets within a clone has been studied using 14C in situ and the adaptative advantage of such facultative physiological integration between ramets of a clone is discussed.
Neighbors ameliorate local salinity stress for a rhizomatous plant in a heterogeneous environment
TLDR
The results indicate that ramets in a locally inferior environment can be helped by their neighbors, but at some cost to the contributing ramet.
THE INTEGRATION OF NEIGHBOURHOOD EFFECTS BY CLONAL GENETS IN SOLIDAGO CANADENSIS
TLDR
The results suggest that clones integrate local neighbourhood variation and that the response of a given ramet to interference from a neighbour species is partly dependent upon the experiences of its interconnected sibling ramets.
PHYSIOLOGICAL INTEGRATION AMONG INTRACLONAL RAMETS IN SOLIDAGO CANADENSIS
TLDR
The results show that new daughter ramets are physiologically dependent upon resources translocated from their parental clone and that this dependency declines with time, and that establishment and competitive ability are increased equitably among genets, and genets are buffered against localized "patch-specific" selection.
PATTERNS OF CARBON ALLOCATION IN AN ARCTIC TUNDRA GRASS, DUPONTIA FISCHERI (GRAMINEAE), AT BARROW, ALASKA
TLDR
There was no autoradiographic evidence during the season to indicate storage of large amounts of mobilizable photosynthate in the stem base or rhizome of a tiller at the time these field studies were carried out.
