Pollen limitation and resource limitation affect the reproductive success of Medicago sativa L. [PDF]
BMC Ecology, 2018 Background A large proportion of the flowers and ovules of plants do not develop into fruits and seeds. Plant reproduction may be limited because of pollen limitation and resource limitation. Medicago sativa L.

Does pollen limitation limit plant ranges? Evidence and implications. [PDF]
Philos Trans R Soc Lond B Biol Sci, 2022 Range limits often involve declines in sexual reproduction, reducing fitness, dispersal, and adaptive potential at range edges. For plants, sexual reproduction is frequently limited by inadequate pollination.

Heatwaves exacerbate pollen limitation through reductions in pollen production and pollen vigour. [PDF]
AoB PlantsIncreasingly frequent heat waves threaten the reproduction of flowering plants; compromising the future persistence, adaptive capacity, and dispersal of wild plant populations, and also the yield of fruit-bearing crop plants. Heat damages the development

Pollen limitation of native plant reproduction in an urban landscape. [PDF]
Am J Bot, 2022 Premise Evidence suggests that bees may benefit from moderate levels of human development. However, the effects of human development on pollination and reproduction of bee‐pollinated plants are less‐well understood.

A test of balanced fitness limitations theory: Pollen limitation in plants [PDF]
Ecology and EvolutionWhen reproductive success is determined by the relative availabilities of a series of essential, non‐substitutable resources, the theory of balanced fitness limitations predicts that the cost of harvesting a particular resource shapes the likelihood that

Fruit Set in Avocado: Pollen Limitation, Pollen Load Size, and Selective Fruit Abortion [PDF]
Agronomy, 2021 Avocado is a woody perennial fruit crop originating in Central America and Mexico domesticated and cultivated in the Americas since pre-Columbian times, currently cultivated in subtropical, tropical, and Mediterranean climates worldwide, with increasing ...

Pollen limitation and xenia effects in a cultivated mass-flowering tree, Macadamia integrifolia (Proteaceae). [PDF]
Ann Bot, 2022 BACKGROUND AND AIMS Pollen limitation is most prevalent among bee-pollinated plants, self-incompatible plants, and tropical plants. However, we have very little understanding of the extent to which pollen limitation affects fruit set in mass-flowering ...

Linking pollen limitation and seed dispersal effectiveness.
Ecology Letters, 2023 Seed production and dispersal are crucial ecological processes impacting plant demography, species distributions and community assembly. Plant-animal interactions commonly mediate both seed production and seed dispersal, but current research often ...

Effective population size mediates the impact of pollination services on pollen limitation. [PDF]
Proc Biol SciInadequate pollen receipt limits flowering plant reproduction worldwide. Ecological causes of pollen limitation (PL), like pollinator scarcity and low plant abundance, have been a primary research focus.

Enhanced leaky sex expression in response to pollen limitation in the dioecious plant Mercurialis annua. [PDF]
J Evol Biol, 2021 In dioecious plants, males and females frequently show ‘leaky’ sex expression, with individuals occasionally producing flowers of the opposite sex. This leaky sex expression may have enabled the colonization of oceanic islands by dioecious plant species,
