These plants all co‐occur in fens in southeastern Michigan and represent a spectrum of clonal growth forms from strong clumpers to runners with long rhizomes. Varying growth, allocation and competition traits produced the largest and most uniform responses in population growth among species, while variation in architectural traits produced.

The rising interest in this area of plant ecology can be partly attributed to the great success of the clonal growth strategy, clearly indicated by the high proportion (%) of clonal plants in surveyed plants of central Europe (Klimeš et al. ).

Clonal growth enables plants to uptake nutrition from multiple sites through horizontal organs (Evans and Cain, ), share limited resources among ramets (Alpert, ), store resources in below-ground clonal structures to persist through cold seasons (Venn and Morgan, ), and increase floral displays, thus attracting more pollinators Author: Yongqian Gao, Jinxuan Zheng, Xiangqun Lin, Fan Du.
The proximate effects of clonal growth traits (such as lateral spread) occur only at the scale of individual plants. There are number of candidate processes through which these clonal growth traits may affect local abundance, but patterns identified in the data can Cited by: Introduced, invasive, clonal plants often spread both via seed dispersal and vegetative growth.

For example, in a combined demographic–molecular approach to study growth patterns, reproduction and spatial expansion at the ramet level, it was possible to reveal spatio-temporal patterns at the genet level, and thus the characteristics particularly relevant to clonal life histories and population viability (Araki et al., ; see also de Cited by: A comparison of plant communities on the basis of their clonal growth patterns Article (PDF Available) in Evolutionary Ecology 18() September with Reads How we measure 'reads'.
The growth and mortality patterns of the clonal forb Urtica dioica were investigated at the level of the individual shoot in two growing seasons, andin a natural stand. Shoot height and diameter at ground level of each shoot tagged in spring were measured repeatedly five times during the growing season.
Answers to some of these will bear on appropriate ways to model clonal growth in future models, as well as whether non-allometric data on allocation should be re-interpreted.
Answers to others would suggest specific mechanisms driving rates and patterns of clonal growth that could be further explored with models and other kinds of experiments. 1. Introduction. In temperate zones, 65–70% of vascular plant species are clonal, having the capacity to reproduce asexually (Klimeš et al., ).Growth and spatial spread in clonal plants occur both by above-ground and below-ground modular reiteration of genetically-identical units called ramets, consisting of storage organs (e.g.
bulbs, corms, and tubers) connected through vegetative. Highlights Provide a PDE model adapted to clonal plant competition thanks to cross non linear diffusion. We have shown that pattern forming instability cannot occur in general competition systems if the exclusion ability of both species is small even if the diffusions are degenerated.
Propose a nonlinear reaction-diffusion systems to be a surrogate model for phalanx-guerilla species competition. The model described here and in the companion papers (Nevai and Vance in review a, b) is a mathematically convenient idealization of our conception of undisturbed southern California clonal salt marsh plant populations during long periods of undisturbed vegetative growth.
Perhaps this idealization also resembles nature elsewhere such as. Clonal plants reproduce by generating new plants from a piece of an existing one without the need of producing seeds or spores. They form a whole family of plants, including terrestrial and marine species. However, the specific features of clonal growth are not taken into account in prototypical models to study vegetation patterns.
() presented a very promising model, which incorporates effects of clonal plant activity on spatial patterns of resource availability, and thereby succession.
Predictions from models such as this should be combined with empirical studies, e.g. field and greenhouse experiments combining the technique of severing inter-ramet connections and. Ring shaped patches of clonal plants fascinated plant ecologists since long time. In this work we review the reports on the occurrence of ring pattern in different environmental conditions, the.
This paper reviews studies on growth and size-structure dynamics of shoots and clones in clonal plants in comparison with those in non-clonal plants, and discusses the characteristics of clonal plants.
The mode of competition between individuals (symmetric versus asymmetric, degree of competitive asymmetry), growth dynamics of individuals, allocation pattern between organs and spatial pattern.
A simplified model of clonal plant growth is formulated, motivated by observations of spatial structures in Posidonia oceanica meadows in the Mediterranean Sea. Two levels of approximation are considered for the scale-dependent feedback terms.
Both take into account mortality and clonal, or vegetative, growth as well as competition and facilitation, but the first version is nonlocal in space. Clonal plants reproduce by generating new plants from a piece of an existing one without the need of producing seeds or spores.
They form a whole family of plants, including terrestrial and marine species. However, the specific features of clonal growth are not taken into account in prototypical models to study vegetation patterns. On the other hand, including all details leads to a.
Flowering plants possess an unrivaled diversity of mechanisms for achieving sexual and asexual reproduction, often simultaneously. The commonest type of asexual reproduction is clonal growth (vegetative propagation) in which parental genotypes (genets) produce vegetative modules (ramets) that are capable of independent growth, reproduction, and often dispersal.
The clonal growth pattern and demography of clonal fragments (aggregation of ramets derived from a common parent ramet) in the pseudoannual plant Trientalis europaea were studied in field conditions from to During this period the population of clonal fragments declined, with a half-life of years.
Number and size of the clonal progeny and stolon length were positively related to. This study was performed to analyse how a vegetative propagation pattern of plants affects the coexistence of species and subsequent species richness of the community.
We compared community average clonal growth in the herbal communities of forests, wooded meadows, and open meadows in Laelatu, Estonia. Abstract. Aim: Patterns of plant functional traits related to clonality (clonal growth modes; CGM) in plant communities were studied and hypotheses on the importance of the selected traits in plant communities supported by soils differing in moisture and nutrient status were tested.
Material and Methods: Selected plant functional traits, such as the position of the mother‐daughter plants. We examine patterns of clonal traits and below‐ground bud bank traits in plant communities over a large set of temperate vegetation types.
We asked (i) how clonal traits are distributed in different community types and (ii) what are within‐community patterns of these traits as an indication of their role in species coexistence and community.cover of clonal plants, which may be considered as a measure of their success in comparison with non-clonal species, increased with soil moisture and was not significantly affected by nitrogen (Fig 2a, b).
The dominance of clonal plants was expressed earlier in moist seres (Fig. 2c).Modeling Investments in Seeds, Clonal Offspring, and Translocation in a Clonal Plant Article (PDF Available) in Ecology 80(4) January with Reads How we measure 'reads'.
