Clonal integration in homogeneous environments increases performance of Alternanthera philoxeroides
Oecologia, 2015Physiological 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.

Integration of Demographic Annual Variability in a Clonal Desert Cactus
Ecology, 2001Spatial and temporal variability influence the structure and dynamics of perennial plant populations. In order to investigate the consequences of this environmental heterogeneity on population and life history traits of a perennial plant with a complex life history, four size-classified population matrix models were employed (i.e., annual, mean ...

The anthropogenic displacement of species around the world results in new environmental situations where native and exotic species coexist. Exotic plants have to face native herbivores, and interactions between introduced plants and native herbivores seem to play an important role in the invasiveness of some exotic plant species. We studied the role of

Abstract 3294: Clonal evolution and integral analysis of hepatoblastoma
Cancer Research, 2015Abstract [Background] Hepatoblastoma (HB) is a rare and heterogeneous childhood malignancy of liver. It is mainly affecting young children in the first 2 years of life, underscoring the unique sensitivity of the immature liver to tumorigenesis.

Thoughts on clonal integration: Facing the evolutionary context
Evolutionary Ecology, 1995In this essay, I have pointed out that the appropriate evolutionary context for plant clonality dictates a focus on the impact of the derived trait of potential independence of subunits on the evolutionarily primitive trait of obligate interdependence of plant subunits, i.e. the advantages of independence. This fact prescribes a major shift in approach

Effect of systemic diseases on clonal integration: modelling approach
Evolutionary Ecology, 2007Systemic disease spread has been suggested as a possible disadvantage of clonal plant integration. As connected ramets have higher risk of being infected, disease should cause a selective pressure against clonality. Since experimental tests of this hypothesis are not easy to perform, we chose a modelling approach, by which we could easily separate ...

Resource sharing between ramets of clonal plants is a well-known phenomenon, which allows stoloniferous and rhizomatous species to internally translocate water, mineral nutrients and carbohydrates from sites of high supply to sites of high demand. The mechanisms and implications of resource integration in clonal plants have extensively been studied in ...

Clonal integration plays an important role in clonal plant adapting to heterogeneous habitats. It was postulated that clonal integration could exhibit positive effects on nitrogen cycling in the rhizosphere of clonal plant subjected to heterogeneous light conditions.

Clonal integration and effects of simulated herbivory in old-field perennials
Oecologia, 1988We compared the growth, phenology and leaf demography of partly defoliated, connected shoots with that of partly defoliated, severed shoots in four old-field perennials (Solidago canadensis, S. altissima, S. gigantea, Aster lanceolatus) with differing genet architectures (rhizome systems), in a common garden and in the field.

Clonal plant research: proliferation, integration, but not much evolution
American Journal of Botany, 1999The vast majority of plants are modular i.e., made up of reiterated pieces. Plant pieces also tend to be highly totipotent. You can regenerate a whole plant from just a tiny fragment of tissue. The ultimate elaboration of modularity and totipotency is clonal growth: one plant gives rise to another gives rise to another gives rise to another with no sex
