DOI: 10.1002/ajb2.1342
Abstract: PREMISE Hermaphroditic plants commonly reproduce through a mixture of selfing and outcrossing. The degree to which outcrossing rates reflect the availability of outcross pollen, genetic differentiation in the ability to autonomously self-fertilize, or both is… read more here.

DOI: 10.1002/ajb2.16109
Abstract: PREMISE Plants are facing increased risk of heat stress with global climate change. Reproductive tissues are particularly sensitive which can result in lower plant fitness. Floral shading and closure are possible mechanisms to limit heat… read more here.

DOI: 10.1002/ajb2.16123
Abstract: PREMISE OF THE STUDY Changes to flowering time caused by climate change could impact plant fecundity, but studies that compare the individual-level responses of phenologically distinct, co-occurring species are lacking. We assessed how variation in… read more here.

DOI: 10.1002/ece3.3397
Abstract: Abstract Studies of species' range limits focus most often on abiotic factors, although the strength of biotic interactions might also vary along environmental gradients and have strong demographic effects. For example, pollinator abundance might decrease… read more here.

DOI: 10.1016/j.jaridenv.2020.104408
Abstract: Abstract Animal pollination is one of the most important ecosystem services that benefit both natural plant communities and plant crops. A failure in pollination service can result in pollen limitation of fruit and seed set.… read more here.

DOI: 10.1093/aob/mcab050
Abstract: BACKGROUND AND AIMS Most angiosperms rely on pollinators to transport pollen and effect fertilization. While some floral visitors are effective pollinators, others act as thieves-consuming pollen but effecting little pollination in return. The importance of… read more here.

Pollen limitation, reproductive success and flowering frequency in singleâflowered plants
Sign Up to like & getrecommendations! Published in 2018 at "Journal of Ecology"
DOI: 10.1111/1365-2745.12834
Abstract: Flowering plants exhibit striking interspecific and intraspecific variation in flower number, which strongly influences the reproductive success of animal-pollinated plants. However, the reproductive consequences of producing a single flower are poorly understood. Here, we test… read more here.

DOI: 10.1111/ele.13171
Abstract: In many perennial wind-pollinated plants, the dynamics of seed production is commonly known to be highly fluctuating from year to year and synchronised among individuals within populations. The proximate causes of such seeding dynamics, called… read more here.

DOI: 10.1186/s12870-021-03211-2
Abstract: Background Reproduction in most flowering plants may be limited because of the decreased visitation or activity of pollinators in fragmented habitats. Hedysarum scoparium Fisch. et Mey. is an arid region shrub with ecological importance. We… read more here.
