This study is the first to demonstrate pollen limitation in a mass-flowering tree.

Herbivores can cause dioecious plants to partly swap sex
Rather than inherently being 'male' or 'female', Mercurialis annua can produce flowers as a plastic response to its environment.

Where Have All The Good Men Gone? Don’t Despair – Make Some Yourself (That’s What Plants Do..)
Observed rates of evolution in the experiment were among the highest yet recorded.

Hybridisation of native and foreign Sorbus trees in the Polish Carpathian mountains
Sorbus is a highly diverse tree genus but is this the result of hybridisation and introgression between native and foreign species?

Do flowers produce scent when they’re not expecting visitors?
The study demonstrates extensive variation in floral scent among populations of a geographically widespread species, Arabis alpina.
Within a mixed species, annuals self-pollinate more than perennials
A smaller stigma-anther separation in annuals seems to indicate a genetic basis for mating system differences.

Variation in reproduction and genetic diversity across seagrass meadows in Western Australia
How do reproductive effort, genetic diversity and mating systems vary across the range of a seagrass population?
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

Flowers evolve to balance the risks and rewards of self-pollination
The longer a plant waits to self-pollinate, the longer it has to attract pollen from outside. But waiting too long can have consequences.
Mating system, ploidy and competition in Capsella species
Capsella is a model genus for studying the transition from outcrossing to selfing, with or without change in ploidy levels. The genomic consequences and changes in reproductive traits (selfing syndrome) associated with...

Evolution of mating system, life history, and photosynthetic physiology in Clarkia
In the western United States, Clarkia (Onagraceae) taxa vary in mating system, life history, and photosynthetic physiology. Self-fertilizing taxa bloom earlier in the year and have higher rates of photosynthesis than...
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.
Reproductive traits affect the rescue of valuable and endangered multipurpose tropical trees
Conservation strategies are urgently needed for widely used tree species. Increasing numbers of species are threatened by overexploitation and their recovery might be poor due to low reproductive success and poor...

Variation in outcrossing and photosynthetic rates in Clarkia reveals independent evolutionary transitions
Adaptive hypotheses to explain the evolution of self-fertilisation in plants are well-characterised, but alternative evolutionary pathways are underexplored. The mating systems and photosynthetic rates of some sister...
