Invasive Alien Clonal Plants Are Competitively Superior Over Co-Occurring Native Clonal Plants [PDF]
Perspectives in Plant Ecology, Evolution and Systematics, 2019 Abstract Alien plant invasions are a major component of global change, and can severely threaten local floras and global biodiversity. A striking pattern of invasive floras is that many of the world’s worst invasive plants are clonal species. However, it is still unclear whether invasive clonal plant species are in general competitively superior over

Adaptive Strategies Employed by Clonal Plants in Heterogeneous Patches
Forests, 2023 Heterogeneity is widespread in natural environments; as a result, connected clonal ramets often live in areas characterized by patches of different resources. Specifically, clonal plants are frequently affected by conditions of heterogeneous water stress.

Next-Gen Plant Clonal Ecology [PDF]
Perspectives in Plant Ecology, Evolution and Systematics, 2021 Abstract Plants with clonal growth can produce multiple potentially independent units, termed ramets. Clonal growth can have important ecological and evolutionary consequences, such as by increasing probability of reproduction, space monopolization, and regeneration after injury; and by permitting physiological integration of connected ramets ...

Modeling Investments in Seeds, Clonal Offspring, and Translocation in a Clonal Plant
Ecology, 1999Clonal plants that can switch facultatively between sexual and asexual re- production may respond plastically to the environment. We constructed a dynamic state variable model to examine how the measure of fitness, ramet and genet mortality, and the assimilation rates of a parent and its clonal offspring influence behavioral investments in ramet growth,

Invasive Alien Plants Benefit More From Clonal Integration in Heterogeneous Environments Than Natives [PDF]
New Phytologist, 2017 What confers invasive alien plants a competitive advantage over native plants remains open to debate. Many of the world's worst invasive alien plants are clonal and able to share resources within clones (clonal integration), particularly in ...

Clonal integration increases tolerance of a phalanx clonal plant to defoliation
Science of The Total Environment, 2017Defoliation by herbivores commonly imposes negative effects on plants, and physiological integration (resource sharing) can enhance the ability of guerilla clonal plants to tolerate stresses. Here we examined whether physiological integration can increase the ability of phalanx clonal plants to withstand defoliation.

Abstract Little is known about the nature of cell-cell interactions in plants as many of the most useful methods for studying this problem are difficult, if not impossible, to employ in plants. One of the most significant technical problems is the tendency of plant cells and tissues to dedifferentiate in new environments. As a result,

Habitat Selection in a Clonal Plant
Science, 1985Rhizomatous growth may permit the nonrandom placement of ramets into different environments, but whether clonal plants are able to use this means to exercise adaptive habitat choice is not known. Western ragweed (Ambrosia psilostachya) plants are shown to preferentially colonize nonsaline soil over saline soil patches, and clones with the strongest ...

Fitness and evolution in clonal plants: the impact of clonal growth
Evolutionary Ecology, 2001Seeds have often been emphasized in estimates of plant fitness because they are the units that carry genes to the next generation, disperse, and found new populations. We contend that clonal growth also needs to be considered when estimating fitness in clonal plants, regardless of whether fitness is measured from a genet or ramet perspective.

In clonal organisms the distribution of a genet is potentially unlimited in space and time. Fitness, defined as the rate of change in number of units carrying a certain allele or allele complex, can be calculated using life cycle graph analysis. The units used should be self-replicating, limited in space and time, and not unnecessarily small.
