▪ Abstract Quantifying the extent to which seed production is limited by the availability of
pollen has been an area of intensive empirical study over the past few decades. Whereas …

Most flowering plants are hermaphroditic, yet the proportion of seeds fertilized by self and
outcross pollen varies widely among species, ranging from predominant self-fertilization to …

Habitat fragmentation is one of the most ubiquitous and serious environmental threats
confronting the long-term survival of plant and animal species worldwide. As species …

Background Some of the most exciting advances in pollination biology have resulted from
interdisciplinary research combining ecological and evolutionary perspectives. For example …

1 Habitat fragmentation and the resulting decline in the local abundance of plant species
can affect biological interactions. We examined the effects of abundance on plant-pollinator …

1. Pollinators visiting large floral displays may probe several flowers in sequence, leading to
geitonogamous (among-flower) self-pollination. To investigate the relationship between …

The evolution of predominant self‐fertilisation frequently coincides with the evolution of a
collection of phenotypes that comprise the 'selfing syndrome', in both plants and animals …

Habitat fragmentation affects both plants and pollinators. Habitat fragmentation leads to
changes in species richness, population number and size, density, and shape, thus to …

The repeated evolutionary transition from outcrossing to self‐pollination in flowering plants
has been suggested to occur because selfing provides reproductive assurance. Reports …

In this chapter, I shall review theoretical models of the evolution of dioecy from
hermaphroditism. I hope to show why theoretical ideas have been important, and why we …
