Distance between pollen donor and recipient influences fruiting success in slickspot peppergrass, Lepidium papilliferum

Importance of Outcrossing for Fruit Production in Slickspot Peppergrass, <em>Lepidium Papilliferum</em> L. (Brassicaceae)

Selective Foraging by Pogonomyrmex salinus (Hymenoptera: Formicidae) in Semiarid Grassland: Implications for a Rare Plant.

Selective foraging by granivores can have important consequences for the structure and composition of plant communities, and potentially severe consequences for rare plant species. To understand how granivore foraging behavior affects common and rare plant species, diet selection should be viewed relative to the availability of alternative seed options, and with consideration of the individual ...

Pollen competition in style: Effects of pollen size on siring success in the hermaphroditic common morning glory, Ipomoea purpurea.

PREMISE OF THE STUDY Pollen size varies greatly among flowering plant species and has been shown to influence the delivery of sperm cells to the eggs. Relatively little is known, however, about the functional significance of within-species genetic variation in pollen size. This study tests whether pollen size influences the relative siring success of a pollen donor during in vivo pollen competi...

بررسی نتایج فن‌آوری کمک باروری در بیماران کاندید تخمک اهدایی و ارتباط آن با متغیرهای فرد دهنده و گیرنده

Background: Oocyte donation and assisted reproductive technology (ART) give women with ovarian failure, advanced reproductive age, inheritable disorders or recurrent implantation failure, the ability to conceive. The success of oocyte donation is reportedly influenced by multiple parameters of the oocyte donor and recipient. The objective of this study was to evaluate the donor and recipient va...

Differential selection on pollen and pistil traits in relation to pollen competition in the context of a sexual conflict over timing of stigma receptivity

Sexual conflict and its evolutionary consequences are understudied in plants, but the theory of sexual conflict may help explain how selection generates and maintains variability. Here, we investigated selection on pollen and pistil traits when pollen arrives sequentially to partially receptive pistils in relation to pollen competition and a sexual conflict over timing of stigma receptivity in ...
