“…These traits affect the success of a species in competing with other species for living resources (e.g., nutrients) [5]. The reproduction behaviors of plants are closely associated with their acquired living resources [6][7][8]. Hence, learning the RA strategy of invasive plants is important for understanding the mechanism underlying successful plant invasion.…”

This study aims to determine the functional traits and reproductive allocation (RA) strategy of the invasive plant Conyza canadensis across different invasion degrees along a latitude gradient in China. Invasion degree did not affect the functional traits and RA strategy of C. canadensis significantly. The high proportion of reproductive biomass (allocating approximately 20% of total biomass into reproductive behaviors) of C. canadensis across different invasion degrees can achieve a fitness advantage in broadening its habitat niches and can eventually attain a successful invasion. The higher proportion of reproductive biomass of C. canadensis in warm temperate and subtropical monsoon climatic zones may play an important role in its successful invasion in the two climatic zones in China. One possible reason for this is that eastern China and northern China, in which C. canadensis vigorously occurs, have the same or similar climate as their natural habitat in the original distribution region. The proportion of reproductive biomass of C. canadensis positively correlated with its total biomass, aboveground biomass, belowground biomass, and vegetative biomass, as well as with its height and leaf size. Meanwhile, temperature rather than annual sunshine hours or annual precipitation was determined to be the most important environmental factor that triggers pronounced effects on the RA strategy of C. canadensis.

“…Plant reproduction behaviors are closely associated with their acquired living resources [13][14]16]. A resource competition exists between growth and reproduction in plants, and the RA strategy of plants controls and balances the dynamics between growth and reproduction [13][14][15][16][17] because living resources in a habitat form one of the most important environmental factors of survival [18]. Meanwhile, the variations in RA strategy play an important role in plant adaptation to environmental changes [14][15]19].…”

“…Generally, herbaceous plants like to choose r strategies (i.e., increased quantity of offspring at the expense of individual parental investment) rather than K strategies (i.e., reduced quantity of offspring with a corresponding increased parental investment) during their life-history [10][11][12]. Thus growth and reproduction in plant populations are likely to be optimized only via improved individual resources and fitness, thereby ultimately resulting in the largest number and maximum fitness of future generations [13][14][15]. Plant reproduction behaviors are closely associated with their acquired living resources [13][14]16].…”

Plant invasion succeeds because of such invader characteristics as fecundity and high-efficiency multiple reproduction modes. The acquisition of individual resources and the benefits of individual fitness are driven by optimum patterns of life history and trade-offs of reproductive allocation (RA) in plants, and variations in RA strategy play an key role in plant adaptation to environmental changes. Thus determining the RA strategy of invasive plants is important for understanding the successful mechanism underlying plant invasion. This study aims to determine the reproductive allocation (RA) strategy of two herbaceous invasive plants (Conyza canadensis and Solidago canadensis) across different cover classes in eastern China. Plant height, maximum branch length, the reproductive branch number, aboveground biomass, the amount of reproductive investment, and the coefficient of RA of the two plants decreased with increasing cover class (although the changes were not pronounced). Thus the two plants may decrease physiological investment on reproductive behavior and reduce RA under competitive conditions because of interspecies competition that progressively decreased and intraspecific competition that gradually increased with increasing cover class. The RA of the two plants may be principally influenced by plant community composition at low cover classes, but by soil pH at high cover classes. This may be the outcome that soil pH of the two plants decreased with increasing cover class significantly. Thus, intraspecific competition for resources may play an important role in the RA strategy of the two plants under high cover class.

“…Elevated environmental CO 2 concentrations have the potential to critically alter plant communities via changes in strategies for allocation to growth and reproduction (Wang, Taub, & Jablonski, ). In the present study, experimental manipulation of CO 2 resulted in the largest discrepancy in reproductive output between gametophytes grown in limited and unlimited conditions.…”

Plasticity of female reproductive resource allocation depends on the presence or absence of prior environmental sex determination in Ceratopteris richardii

Resource allocation plasticity enables individuals to alter patterns of nutrient use between reproductive and vegetative output to better fit their current environment. In sexually labile plant species, abiotic environmental factors can influence expression of dimorphic gender, resulting in environmental sex determination (ESD), which potentially reduces the need for plasticity of resource allocation by preemptively matching an individual’s future nutrient demands to resource availability in its location. Ceratopteris richardii gametophytes exhibit gender‐dependent differences in relative carbon and nitrogen content, and ESD in certain nutrient environments. This study examined whether prior ESD in C. richardii gametophyte populations reduced subsequent plasticity of reproductive allocation compared to instances where no ESD occurred, by quantifying phenotypic responses to reduced P, N, or CO 2 availabilities. All three nutrient‐limited environments resulted in decreased size of egg‐bearing (meristic) gametophytes compared to nonlimited environments, but gametophytes failed to respond to N and CO 2 limitation at the time of sex determination, resulting in no ESD. N limitation resulted in a predictable allometric re‐allocation of resources based on small gametophyte size, whereas CO 2 limitation caused a change in reproductive output consistent with true plasticity. Withholding exogenous P caused ESD and had no effect on relative reproductive output of resultant meristic gametophytes because the size decrease was minor. Under P limitation, ESD matched the resource demands of gender phenotypes to their environment before the onset of developmental dimorphism, reducing the need for large allocation adjustments after sex determination.
