Variation in pollinator quality is fundamental to the evolution of plant-pollinator mutualisms
and such variation frequently results from differences in foraging behavior. Surprisingly …

A wide variety of insect species provide pollination services in natural and agricultural
ecosystems, but in order to quantify their contribution it is necessary to evaluate their …

Bowl-shaped inflorescences, geoflory, dull-coloured flowers and winter flowering suggest
that Protea foliosa is adapted for rodent-pollination. To test this hypothesis, rodents were …

Pollen and nectar are the primary rewards offered by flowers to pollinators. In floral visitors of
some plant species, pollen thieves and nectar robbers cause the reduction in pollen grain …

Premise of research. In hermaphroditic plants, pollen production can enhance fitness
through siring success by attracting pollen-seeking pollinators. However, pollen production …

Pollinator taxa may vary in their contribution to plant outcrossing rates and hence differ in
their influence on plant fitness. In plants that have ornithophilous floral traits (large, deep …

Aloe reitzii var. reitzii is a summer-flowering (February–March) succulent, endemic to a
restricted range within the heavily transformed grasslands of eastern South Africa. Floral …

The movements of birds and small mammals may be affected by spatial and temporal
variation in resource availability. For the genus Aloe, bird abundance and diversity increase …

Plant species that are effective colonisers of transient habitats are expected to have a
capacity for uniparental reproduction and show flexibility in pollination systems. Such traits …

Flowering plants typically use floral rewards to attract animal pollinators. Unlike nectar,
pollen rewards are usually visible and may thus function as a signal that influences landing …
