Observed rates of evolution in the experiment were among the highest yet recorded.

Not All Scarlet Pimpernels Arrange Their Sexual Organs the Same Way to Avoid Pollinating Themselves
When there are unsuitable partners around, Lysimachia arvensis, will alter its herkogamy to favour self pollination over outcrossing with the wrong flowers

Do I need a sexual partner, or is it better to be my own date? The evolution of sexually dimorphic plants
Enantiostyly, a reproductive system characterized by heteromorphic flowers with either left or right style deflection, compels reciprocal pollen transfer between floral types. The potential outcrossing advantage of...
Pollen limitation and reproductive assurance in a fragmented landscape
Humans have transformed landscapes, leaving remnant habitats embedded within a complex matrix. For many plants, the associated factors of decreased population size and increased land-use intensity surrounding them are...

Flower-level developmental plasticity and mating system in Datura
Reductions in herkogamy with flower positions may be expected in environments with either low pollinator abundance or low nutrients.
Mixed mating after the loss of self-incompatibility in a long-living perennial herb
Flowering plants display an extensive range of adaptive floral forms, which are often correlated with their mating systems. The maintenance of contrasting strategies such as those adopted by obligate outcrossers...
Seasonal variation in selfing rate
Flowering plants display considerable variation in mating system, particularly the relative frequency of cross- and self-fertilization. The majority of estimates of outcrossing rate do not account for temporal...
Increased heterosis in selfing populations of a perennial forb
Quantifying the effects of population bottlenecks and inbreeding on genetic variation underlying fitness in natural populations is central to understanding the potential limits to natural selection. One approach is to...

Shifts in mating systems under contrasting environments
Establishment of plant populations in novel environments may generate shifts in floral traits and plant mating systems.

Stamen movements and pollination in Ruta
In Ruta graveolens each stamen elevates to above the flower’s centre for anther dehiscence and then falls back before the next stamen elevates, producing a one-by-one rising and falling pattern of movement. Ren and Tang...
Novel self-pollination mechanism in Roscoea
Delayed selfing is the predominant mode of autonomous self-pollination in flowering plants. Fan and Li investigate the characteristics of reproductive ecology of Roscoea debilis (Zingiberaceae) and report a novel...
