Multiple dimensions of floral rewards drive pollinator behavior and pollen movement
Animal pollinated plants produce a diversity of rewards to attract pollinating insects. Most commonly these are nutritional rewards; either pollen (primarily protein and lipids) and/or nectar (primarily carbohydrates) in varying combinations and qualities. This reward strategy varies inter- and …

Pollen digestion in flower-feeding Scarabaeidae : protea beetles (Cetoniini) and monkey beetles (Hopliini)
… flowering plants and feed on the two most common floral rewards, nectar and pollen. Pollen is nutritionally very valuable, being a rich protein and carbohydrate source. However, the hard and highly resistant outer wall (exine) of the grain is an obstacle that pollen-feeders must overcome in order …

Pollination Biology of <i>Ailanthus altissima</i> (Mill.) Swingle (Tree-of-Heaven) in the Mid-Atlantic United States
To date little information has been collected on the pollination biology of <i>Ailanthus altissima</i> (Mill.) Swingle (tree-of-heaven), an invasive exotic in the U.S. This study was conducted to determine the insect pollinator fauna visiting <i>A. altissima</i> and to study general pollinator …

So happy together? : Pollination and reproductive strategy of two sympatric species of Acanthus L. in Kenya
… towards A. polystachyus. As flowering time and floral morphology of the species are highly similar, it seems likely that habitat fragmentation causes changes in pollination and reproduction of the species. In particular, A. eminens may loose pollinators to A. polystachyus, and receive more …

The pollination and scent ecology of selected Cape milkweeds (Apocynaceae: Asclepiadoideae)
… (Asclepiadoideae, Apocynaceae) possess a complex floral morphology that has made them prime candidates for investigating the evolution of plant-pollinator relationships. In South Africa, the pollination ecology of this diverse group has largely been focused in the summer rainfall region. This …

Effects of systemic fungicides on floral attributes, pollination and fruit aroma in strawberries
… contact with the substance and contaminate floral rewards for pollinators, thus directly impairing the pollinators’ health. Also, the treated plants can be affected by the fungicide, changing their metabolism and/or photosynthesis. It can therefore be expected that the plant-pollinator …
