Sexual selection: an evolutionary force in plants?

- 1 November 2002
It is concluded that sexual selection can be a useful tool when studying the evolution of reproductive traits in plants and by including the evidence from an additional kingdom, a fuller understanding of the processes involved in sexual selectioncan be gained. Expand
Sexual Conflict and Sexually Antagonistic Coevolution in an Annual Plant
It is indicated that recipients are released from the cost of interacting with local pollen donors when crossed with donors from a more distant location, a pattern consistent with a history of sexually antagonistic coevolution within populations. Expand
Effects of Soil pH and Phosphorus on In Vitro Pollen Competitive Ability and Sporophytic Traits in Clones of Viola tricolor

- 1 November 2000
If the response to phosphorus among pollen donors is more pronounced under natural conditions, variation in this environmental factor within populations has the potential to maintain some genetic variation in pollen tube growth rate even if this trait is constantly selected. Expand
Pollen competition reduces inbreeding depression in Collinsia heterophylla (Plantaginaceae)
It is suggested that intermittent inbreeding, which leads to self‐fertilization in plants with genetic loads, may select for traits that enhance pollen competition. Expand
How does breeding system variation modulate sexual antagonism?
This work synthesizes how variation in breeding system can affect the evolution and expression of intra- and inter-locus sexual conflicts in plants and animals and predicts that, in hermaphrodites, SA traits will display lower levels of polymorphism and respond more quickly to selection. Expand
Characterization of olfactory sensory neurons in the white clover seed weevil, Apion fulvipes (Coleoptera: Apionidae).

- 1 October 2012
The antenna of the white clover is analyzed with scanning electron microscopy, and single sensillum recordings with a set of 28 host compounds are used to characterize 18 classes of olfactory sensory neurons (OSNs), showing a remarkable degree of specificity. Expand
Influence of number of pollinations and pollen load size on maternal fitness costs in Collinsia heterophylla: implications for existence of a sexual conflict over timing of stigma receptivity
Costs related to pollen competition have rarely been considered, but are expected in the case of sexual conflict where male and female sexual functions have opposing evolutionary interests. In… Expand
Earlier occurrence and increased explanatory power of climate for the first incidence of potato late blight caused by Phytophthora infestans in Fennoscandia
The strong link between climate and first incidence together with the presented model offers a tool to assess late blight incidence in future climates and shows that models used in decision support systems need to be checked and re-parametrized regularly to be able to capture changes in pathogen biology.

Delayed stigma receptivity in Collinsia heterophylla (Plantaginaceae): genetic variation and adaptive significance in relation to pollen competition, delayed self-pollination, and mating-system…
Phenotypic and genetic variation within populations in the timing of stigma receptivity and anther-stigma contact was substantial, although slightly less for the contact, and an among-genet phenotypic correlation between the traits was not found, indicating that each trait may respond independently to selection, and the trait association may be the result of correlational selection. Expand
Enhancing pollen competition by delaying stigma receptivity: pollen deposition schedules affect siring ability, paternal diversity, and seed production in Collinsia heterophylla (Plantaginaceae).
Fitness advantages of enhancing pollen competition by delaying stigma receptivity in C. heterophylla are suggested, particularly in relation to increased paternal diversity, which was associated with increased seed production. Expand
