Clonal Integration and the Expansion of Phragmites australis
Ecological Applications, 2000The recent expansion of the reed Phragmites australis in western Atlantic salt marshes has become a conservation concern. Historically, Phragmites was restricted to the terrestrial border of marshes, but now it aggressively invades lower elevations.

TRANSLOCATION IN POLYTRICHUM COMMUNE (BRYOPHYTA). II. CLONAL INTEGRATION
American Journal of Botany, 1990Polytrichum commune is a perennial moss that grows by rhizomatous production of interconnected shoots. It possesses a well‐developed internal system of food‐conducting tissue. Liquid scintillation determinations following pulse‐14CO2 treatment of a single shoot in rhizomatously connected groups indicate that tagged photoassimilates are transported into:

High-Throughput Mapping and Clonal Quantification of Retroviral Integration Sites
2017We describe here a method to identify the position of retroviral insertion sites and simultaneously to quantify the absolute abundance of each clone, i.e., the number of cells having the provirus inserted at a given place in the host genome. The method is based on random shearing of the host cell DNA, followed by a linker-mediated PCR to amplify the ...

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 ...

Science of The Total Environment, 2018
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 ...

Evolutionary Ecology, 2004
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 ...
