Flowering plants exhibit two principal life-history strategies: annuality (living and
reproducing in one year) and perenniality (living more than one year). The advantages of …

Charles Darwin recognized that flowering plants have an unrivalled diversity of sexual
systems. Determining the ecological and genetic factors that govern sexual diversification in …

Allee effects are (broadly) defined as a decline in individual fitness at low population size or
density. They can result in critical population thresholds below which populations crash to …

Determining whether seed production is pollen limited has been an area of intensive
empirical study over the last two decades. Yet current evidence does not allow satisfactory …

The loss and fragmentation of natural habitats by human activities are pervasive
phenomena in terrestrial ecosystems across the Earth and the main driving forces behind …

▪ Abstract Mixed mating, in which hermaphrodite plant species reproduce by both self-and
cross-fertilization, presents a challenging problem for evolutionary biologists. Theory …

Many functional-ecological, morphological, and physiological-factors affect the occurrence
of selffertilization. Six modes of self-pollination are distinguished. These differ in whether …

We conducted a comparative analysis to determine life history and ecological correlates of
pollen limitation among 224 species of animal-pollinated flowering plants. To test …

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 …

There is increasing evidence that human disturbance can negatively impact plant–pollinator
interactions such as outcross pollination. We present a meta-analysis of 22 studies involving …
