Flowers that self-shade reduce heat stress and pollen limitation.

American Journal of Botany, 2022
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.

Reconciling Pollen Limitation Theories: Insights From Temperate Oak Masting.

Ecology Letters
Pollen limitation has a considerable influence on forest masting, the highly variable and synchronised seed production, on which forest regeneration and ecosystem dynamics largely rely.

Pollen limitation and its effect on seed germination

Seed Science Research, 2018
In nature, fruit and seed production in many plants have been shown to be pollen limited. Pollen limitation is demonstrated when open-pollinated plants that are hand-supplemented (Ps) with outcross pollen produce more fruits and/or seeds than open ...

Optimal sex allocation under pollen limitation

Theoretical Ecology, 2017
Most flowering plants are simultaneous hermaphrodites. Within species and even within local populations, sex allocation is usually highly plastic. Here, we link pollen sufficiency to the size of pollen-exchanging groups (i.e., pollen neighborhoods) and to pollen transfer efficiency, using an individual-based game-theoretic framework to determine the ...
