A simulation study of the effects of architectural constraints and resource translocation on populam a short-turf grassland. Sensitivity analysis was carried out on relevant parameters around three basic points in the parameter space. Both single-species and two-species systems were studied. (3) It is shown that increasing resource acquisition and growth parameters increase ramet density, genet n

The developmental ecology of mycorrhizal associations in mayapple, ,, Berberidaceae,ayapple rhizome systems suggests that the mycorrhizal relationship is facultative at the ramet level. This conclusion is reinforced by our observation that augmentation of soil phosphate lowers root colonization by AM fungi. We also found that soil phosphate concentrations were depleted by ca. 1% un

Age- and stage-based bud demography of , under contrasting muskox grazing pressure in the High Arct not differ among female, male and vegetative plants in the grazed habitat, where 96% of the plants were grazed. According to the age- and stage-based model, the newest bud generation and the vegetative shoots determine the majority of demographic processes of the plant. Longer-term observations are

The loss of sex in clonal plants, sterility mutations, may also play a significant role in causing reduced sexual fertility. Moreover, environmental suppression of sexual recruitment may facilitate the evolution of genetic sterility because natural selection no longer strongly maintains the many traits involved in sex. In addition

Investigating the community consequences of competition among clonal plants,cies that differ in their natural aggregation (either clumped growth forms, with ramets tightly packed together, or runner growth forms, with ramets loosely spread) and by planting individual ramets of all species evenly spaced throughout a mesocosm. We illustrate how to test predictions to examine

On the evolution of clonal plant life histories,ariation in selectively neutral genetic markers appears as pronounced in populations of clonal as non-clonal plants. However, neutral markers may not reflect heritable variation of life-history traits. Moreover, clonal plants may have been sampled at larger spatial scales. Empirical information on t
