Data from: Geographic variation of reproductive traits and competition for pollinators in a bird-pollinated plant
- 负责人：
- DOI：
- doi:10.5061/dryad.7hp0168
- 摘要：
- limited. To evaluate whether competition from co-occurring sunbird-pollinated species might reduce visitation, we quantified nectar rewards in B. ringens
Data from: Prior selfing can mitigate the negative effects of mutual reproductive interference between coexisting congeners
- 负责人：
- DOI：
- doi:10.5061/dryad.1ck03q4
- 摘要：
- on effects of prior and competing self-pollination, in both Cc and Ccfc. For both species in the field, intraspecific pollinator movements and reproductive success sig

- doi:10.5061/dryad.4gn47
- 摘要：
- complement of most proteins and RNA, limiting selection on the haploid genotype. Plants, however, exhibit extensive expression in pollen, with acti
Data from: A test of a corollary of Allen’s rule suggests a role for population density
- 负责人：
- DOI：
- doi:10.5061/dryad.tq20c08
- 摘要：
- varied inversely with population density. We discuss the relative abilities of sexual selection and ecological competition to explain these results.
Data from: Reconciling extremely strong barriers with high levels of gene exchange in annual sunflowers
- 负责人：
- DOI：

- 摘要：
- on, reproductive asynchrony, immigrant inviability, pollen competition, hybrid seed formation, hybrid seed germination, hybrid pollen fertility, and hybrid seed
Data from: Rapid evolution of reproductive isolation between incipient outcrossing and selfing Clarkia species

- DOI：
- doi:10.5061/dryad.n4mm0
- 摘要：
- me and pollinator preference (for the outcrosser over the selfer) as the strongest barriers. We found that the outcrosser had consistently more competitive pollen, facilitati
Data from: Mating patterns and pollinator mobility are critical traits in forest fragmentation genetics

- DOI：
- doi:10.5061/dryad.g7j86
- 摘要：
- pollen diversity, and that more mobile pollinators tended to dampen these mating-pattern shifts. Together, our findings support the premise that variati
Data from: Male interference with pollination efficiency in a hermaphroditic orchid
- 负责人：
- DOI：
- doi:10.5061/dryad.62sj6
- 摘要：
- t likely mechanism for such male interference is competition for placement on the proboscis of hawkmoth pollinators. Consequently, male competition
Data from: Multiple reproductive barriers separate recently diverged sunflower ecotypes

- 摘要：
- rly in the speciation process and those that arise after speciation is largely complete. In this paper we comprehensively test for reproductive isolation between recent
Data from: Frequency-dependent fitness and reproductive dynamics contribute to habitat segregation in sympatric Jewelflowers

- 摘要：
- of coexistence. Competition may also reduce the fitness of individuals migrating into occupied habitats, yet its effects are insufficient to drive competitive
