Summit areas of oceanic islands constitute some of the most isolated ecosystems on earth and are highly vulnerable to climate change and introduced species. Within the unique high-elevation communities of Tenerife...

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...

Plasticity of key floral traits influences pollinator attraction
Examining the effects of multiple components of pollen deposition (varying according to quantity, source and timing) and pollen removal on key floral traits in Sabatia angularis, Spigler demonstrates the highly...
Pollinator decline, high pollen limitation and low progeny quality
Interactions between species are especially sensitive to environmental changes. The interaction between plants and pollinators is of particular interest given the potential current global decline in pollinators. Reduced...
Pollen limitation and reduced reproductive success
Even though P. virginiana is a widespread species, fragmented populations experience significant reductions in fruit set and pollen limitation.

Avoidance of interspecific pollen transfer in Pedicularis
Plants surrounded by individuals of other co-flowering species may attract more pollinators but can suffer a reproductive cost from interspecific pollen transfer. Yang et al. compare pollination and reproduction in...
Pollen receipt and quality in endemic-rich communities
The magnitude of pollen limitation is highly variable among habitats, species and differing plant communities. Alonso et al. analyse natural variability in pollen receipt and tube formation, and compare pollen quality...
Pollen limitation in hummingbird-pollinated plants
Many species of hummingbird-pollinated plants in a tropical montane rain forest experience pollen limitation.
Shifts in mating systems under contrasting environments
Establishment of plant populations in novel environments may generate shifts in floral traits and plant mating systems.
Costs of reproduction in a gynodioecious species
In gynodioecious species hermaphroditic plants coexist with female plants. Toivonen and Mutikainen find that experimentally increased reproductive output leads to differential costs of reproduction in the gynodioecious...
Co-flowering species and pollination interactions
The presence of co-flowering species can alter pollinator foraging behaviour and positively or negatively affect reproductive success of individual species. Liao et al. investigate interactions between Pedicularis...
Plants, Pollination and Paywalls
We put The natural history of pollination and mating in bird-pollinated Babiana (Iridaceae) live on the Annals of Botany site this week. It’s been covered in the press, notably by the BBC, Plant has evolved a...

Pollinator and herbivore effects on Erysimum
Erysimum capitatum (Brassicaceae) is a widespread and variable plant species with generalized pollination that is attacked by a number of herbivores. Lay et al. find that individuals of E. capitatum are visited by...
