Interactive effects of drought and pollen intensity on seed production
Seed production of flowering plants is influenced by water availability and pollen deposition, but is there an interaction between these factors?

Flies can be pollen thieves but plants deal with them
Some plants tackle thieves and pollinators eating pollen by producing enough both to feed visitors and fertilise available ovules.

How will plants cope with fewer pollinators?
A recent paper highlights a critical research gap, and reveals the potential for finding new data in old places.

Botanists find out who’s the daddy
Growing a fruit is only one way of passing your genes on to the next generation if you’re a plant. You could also send pollen to another plant. But what factors influence siring success? Dorothy Christopher and...
Reproductive assurance weakens pollinator-mediated selection on flower size
The consequences of delayed selfing by reproductive assurance for selection on flower size in mixed-mating species is relevant to understand the evolution of plant breeding systems.

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...
Evolution of plant mating systems drives pollen limitation
Seed production of plants is rarely maximized, because it is limited by pollen receipt. Previous theories have shown that ecological mechanisms can drive the evolution of pollen limitation. Devaux et al.’s model shows...
A review of European studies on pollination networks and pollen limitation, and a case study designed to fill in a gap
Europe has a long history of human use of grassland ecosystems as hay meadows, yet these ecosystems have very high biodiversity. These ecosystems have recently become threatened by changing land use patterns and...
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...

Plant biotic interactions and fitness in habitat edges
Habitat variations influence the richness and composition of insect guilds. This affects plant reproduction, which depends upon functional relationships with insects involving both pollination and predation. The impact...

Stigmatic limitations on reproductive success in a paleotropical tree
Success in reproduction is subject to the successful initiation as well as successful completion of a chain of consecutive events starting from flower formation and ending with viable seed production. A recent article...
The role of herbivory in the selection of floral traits
Pollinators are often given precedence as the primary drivers behind the evolution of floral traits. Yet a growing body of research is beginning to stress the importance of other significant selective agents...
Species-environment interactions changed by introduced herbivores
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...
