Data from: Environmental veto synchronizes mast seeding in four contrasting tree species
- 负责人:
- 摘要:
- Synchronized and variable reproduction by perennial plants, called mast seeding, is a major reproductive strategy of trees. Resource budget mod

Data from: Evidence for enemy release and increased seed production and size for two invasive Australian acacias
- 负责人:
- 摘要:
- r tree. Synthesis. Acacia dealbata and A. longifolia escape pre-dispersal predation in the introduced range and display a higher production of fully developed seed

Data from: The consequences of demand-driven seed provisioning for sexual differences in reproductive investment in Thalictrum occidentale
- 负责人:
- 摘要:
- to the demands of flower and seed production may cause sexual dimorphism. We assess the occurrence of demand-driven seed allocation by females and its implicati

Data from: Neo-allopatry and rapid reproductive isolation
- 负责人:
- 摘要:
- reproductive isolation has not been demonstrated for such neo-allopatric species. We grew seeds from three species of Centaurea (C. solstitialis, C. calcitrapa

Data from: Demographic consequences of greater clonal than sexual reproduction in Dicentra canadensis
- 负责人:
- 摘要:
- ilarly sized nonflowering plants, suggesting energy trade-offs between sexual and clonal reproduction at the individual level. Seed production had negligible

Data from: Declines in pinyon pine cone production associated with regional warming
- 负责人:
- 摘要:
- , increasing temperature may negatively influence reproductive output of other conifers. Further investigation into the full geographic and taxonomic extent of these seed

Data from: Individual resource limitation combined with population-wide pollen availability drives masting in the valley oak (Quercus lobata)

- mast fruiting masting resource limitation pollen limitation reproductive ecology Reproductive ecology phenological synchrony
- 摘要:
- t to analyze seed production of 84 valley oaks (Quercus lobata) in central coastal California. Individual trees varied tremendously in their seed production pattern

Data from: Strong sexual selection in males against a mutation load that reduces offspring production in seed beetles
- 负责人:
- 摘要:
- and that mutations affecting male reproductive success have pleiotropic effects on population productivity, but empirical support for these assumpti

Data from: High genotypic diversity and strong spatial structure in populations of Trifolium alpestre with low seed production
- 负责人:
- 摘要:
- s have evidently opened new opportunities for the successful sexual reproduction from the permanent soil seed bank and have thus avoided the losse

Data from: Within-season synchrony of a masting conifer enhances seed escape

- 摘要:
- reproductive synchrony. Thus, this masting plant escapes seed predation in numbers through interannual synchrony in seed production and in time through intra-annual
