This study is the first to demonstrate pollen limitation in a mass-flowering tree.
Rather than inherently being ‘male’ or ‘female’, Mercurialis annua can produce flowers as a plastic response to its environment.
Observed rates of evolution in the experiment were among the highest yet recorded.
Sorbus is a highly diverse tree genus but is this the result of hybridisation and introgression between native and foreign species?
The study demonstrates extensive variation in floral scent among populations of a geographically widespread species, Arabis alpina.
A smaller stigma-anther separation in annuals seems to indicate a genetic basis for mating system differences.
How do reproductive effort, genetic diversity and mating systems vary across the range of a seagrass population?
When there are unsuitable partners around, Lysimachia arvensis, will alter its herkogamy to favour self pollination over outcrossing with the wrong flowers
The longer a plant waits to self-pollinate, the longer it has to attract pollen from outside. But waiting too long can have consequences.
Reductions in herkogamy with flower positions may be expected in environments with either low pollinator abundance or low nutrients.
