“…Thus, V. spinulosa shifted the balance between the two reproductive modes to adapt to different environments. Trade-offs in resource allocation between sexual and clonal reproduction have been demonstrated for aquatic species (Thompson and Eckert 2004, Reusch 2006, Van Drunen and Dorken 2012, whereas other studies failed to detect clear trade-off relationships (Eckert et al 2000, Han et al 2011. Based on the variability and trade-off of resource allocation between these two reproductive modes, we inferred that different populations of this species living in contrasting habitats are able to use different reproductive strategies.…”

Ecosphere 9(1):e02070. 10.1002/ecs2.2070 Abstract. Variations in water level profoundly affect functional stability of freshwater ecosystems, as well as macrophyte growth and reproduction. Although the trade-off between allocation to clonal and sexual reproduction in clonal plants can be influenced by a variety of environmental factors, whether variations of reproductive allocation (RA) in response to different environments are driven only by a sizedependent effect (apparent plasticity) or whether RA can also change independently of plant size (true plasticity) is uncertain. We conducted an experiment in nine outdoor mesocosms (6400 L) to investigate the response of clonal and sexual reproduction and vegetative growth of a perennial submerged macrophyte Vallisneria spinulosa at water depths of 50, 100, or 150 cm. We evaluated size-dependent and sizeindependent effects of water depth on sexual and clonal RA. Deep water reduced vegetative size and sexual output (mass of fruits produced), but increased tuber production of V. spinulosa. There was an apparent trade-off between reproductive modes in terms of biomass investment; plants in deep water allocated more resources into clonal propagation and reduced investment in sexual reproduction compared to plants in shallow or intermediate water. Slopes of allometric relationships (sexual vs. vegetative biomass and clonal vs. vegetative biomass) were significantly affected by water depth. Shifts in sexual RA in response to varying water depths were largely size-dependent, but there were also size-independent effects. In contrast, size-independent effects were more important than effects of size changes in determining clonal RA. We concluded that V. spinulosa adapted to a water-depth gradient by plastic trade-offs between clonal propagation and sexual reproduction. Furthermore, a size-independent effect on RA suggests a flexible reproductive strategy that could be critical for plant performance in changing aquatic environments.

“…However, in a habitat with higher plant density or intense competition, many smaller corms would not develop into flowering individuals (Zhao, 2011). Other research also showed that S. trifolia can change its sex ratio and resource allocation modes in different individual densities (Han et al, 2011). Therefore, increasing resource allocation to big corms in a competitive environment might contribute to population maintenance in S. graminea.…”

“…Several previous studies have shown that the trade‐offs lead to varied conclusions in conditions with different nutrient levels or environmental conditions. For example, several studies detected a negative trade‐off relationship between reproductive modes (Snow & Whigham, ; Thompson & Eckert, ; Stark et al, ; Thiele et al, ; Van Drunen & Dorken, ), whereas others did not find a clear trade‐off relationship (Cain & Damman, ; Mendoza & Franco, ; Liu et al, ; Thiele et al, ; Han et al, ). The current study revealed that in low nutrient (control) or nutrient‐abundant (add‐N + P) conditions, there are no trade‐off relationships between S. graminea aboveground and belowground reproductive components.…”

Varied nutrient sources can influence the plasticity of reproductive strategies in monoecious species differently. We examined the plasticity of sexual and clonal reproductive components in distinct nutrient sources in a monoecious species, Sagittaria graminea Michx. The results showed that for aboveground reproductive components, in rich-phosphorus and low-nitrogen conditions, the species produced more male flowers, whereas female flowers did not significantly increase in number compared to low-phosphorus and low-nitrogen conditions (control). In richnitrogen and low-phosphorus conditions, the species produced more flowers, particularly female, and more seeds, compared to the control conditions. In the rich-nitrogen and rich-phosphorus conditions, plants increased male flowers, female flowers, total flower number, synchronously, as well as seed production. For the belowground reproductive components, in the rich-phosphorus conditions, the plants produced bigger corms than in the richnitrogen and control conditions, which further enhanced their competitiveness against companion species. In richnitrogen conditions, the plants produced more medium and small corms, and relatively more and longer stolons, which were useful in expansion and invasion of more space. Furthermore, the species displayed trade-off relationships between the aboveground and belowground reproductive components in unbalanced nutrient conditions (add-N or add-P). However, in low nutrient levels (control) or in nutrient abundant (add-N þ P) conditions, there were no significant trade-off relationships between the aboveground and belowground reproductive components, based on quantities.

PremiseMast flowering/seeding is often more extreme in lower‐resource environments, such as alpine compared to lowland habitats. We studied a masting herb that had less extreme masting at higher elevations, and tested if this difference could be explained by higher photosynthetic productivity and/or lower reproductive investment at the higher‐elevation sites.MethodsWe examined the relationship between flowering intervals and carbon budget (i.e., the balance between reproductive investment and annual carbon fixation) in a masting herb, Veratrum album subsp. oxysepalum, across five lowland and six alpine populations in northern Japan. We evaluated the previous flowering histories of individual plants based on rhizome morphology and analyzed the masting patterns of individual populations. Total mass of the reproductive organs, as a proxy of reproductive investment, was compared between the lowland and alpine populations. Annual carbon fixation was estimated on the basis of photosynthetic capacity, total leaf area per plant, and seasonal transition of light availability.ResultsInterval between high‐flowering years was shorter and total reproductive investment was smaller in the alpine than in the lowland populations. Owing to its high photosynthetic capacity and continuous bright conditions, annual carbon fixation per plant was 1.5 times greater in alpine habitat than in lowland habitat. These results suggest that V. album alpine populations have shorter flowering intervals than lowland populations due to faster recovery from energy loss after reproduction.ConclusionsOur study demonstrated that masting intervals in V. album populations can be explained by habitat‐specific carbon budget balances.
