Masting promotes individual- and population-level reproduction by increasing pollination efficiency.
Masting is a reproductive strategy defined as the intermittent and synchronized production of large seed crops by a plant population. The pollination efficiency hypothesis proposes that masting increases pollination success in plants. Despite its general appeal, no previous studies have used long-term data together with population- and individual-level analyses to assess pollination efficiency ...
متن کاملUnderstanding plant reproductive diversity
Flowering plants display spectacular floral diversity and a bewildering array of reproductive adaptations that promote mating, particularly outbreeding. A striking feature of this diversity is that related species often differ in pollination and mating systems, and intraspecific variation in sexual traits is not unusual, especially among herbaceous plants. This variation provides opportunities ...
متن کاملINVITED REVIEW The evolution of bat pollination: a phylogenetic perspective
†Background Most tropical and subtropical plants are biotically pollinated, and insects are the major pollinators. A small but ecologically and economically important group of plants classified in 28 orders, 67 families and about 528 species of angiosperms are pollinated by nectar-feeding bats. From a phylogenetic perspective this is a derived pollination mode involving a relatively large and e...
متن کاملPterandra pyroidea: a case of pollination shift within neotropical Malpighiaceae.
BACKGROUND AND AIMS Most Neotropical species of Malpighiaceae produce floral fatty oils in calyx glands to attract pollinating oil-collecting bees, which depend on this resource for reproduction. This specialized type of pollination system tends to be lost in members of the family that occur outside the geographic distribution (e.g. Africa) of Neotropical oil-collecting bees. This study focused...
متن کاملSexual Propagation of Persian Shallot (Allium hirtifolium) Through Manual Pollination and In vitro Ovary Germination
For sexual reproduction of Allium hirtifolium, collected bulbs were planted in the field. In order to develop ovary embryo and seed setting, control self-pollination and natural open pollination took placed using honey bees under cages. Ovary development and seed setting of A. hirtifolium extraordinary were affected by pollination and there was a significant difference between mean effect of se...
