WHAT GOVERNS PROTEIN CONTENT OF POLLEN: POLLINATOR PREFERENCES, POLLEN–PISTIL INTERACTIONS, OR PHYLOGENY?
Pollen ranges from 2.5% to 61% protein content. Most pollen proteins are likely to be enzymes that function during pollen tube growth and subsequent fertilization, but the vast range of protein… Expand
The ecology of oil flowers and their bees
- S. Buchmann
Nectar and/or pollen are the only floral rewards traditionally investigated. Such myopia has impeded full understanding of flower-visiting organisms. Flowers in fact offer a great diversity of… Expand
The Forgotten Pollinators
Consider this: Without interaction between animals and flowering plants, the seeds and fruits that make up nearly eighty percent of the human diet would not exist.In "The Forgotten Pollinators,"… Expand
Restoration Biology: A Population Biology Perspective
A major goal of population biologists involved in restoration work is to restore populations to a level that will allow them to persist over the long term within a dynamic landscape and include the… Expand
Sonication dispensing of pollen from Solanum laciniatum flowers
1. Sonication is a seemingly effective method for foraging insects to extract pollen rapidly from poricidal anthers. However, without a dispensing mechanism to limit the pollen extraction a single… Expand
Trumpet Flowers of the Sonoran Desert: Floral Biology of Peniocereus Cacti and Sacred Datura
- R. Raguso, C. Henzel, S. Buchmann, G. Nabhan
- International Journal of Plant Sciences
- 1 November 2003
The floral biology of night‐blooming Peniocereus cacti and Datura plants was studied in North America's Sonoran Desert. In populations of two rare cactus species (Peniocereus greggii and Peniocereus… Expand
A biophysical model for buzz pollination in angiosperms.
Abstract The stamens of most of the world's flowering plants are longitudinally dehiscent, releasing their pollen passively, whereupon floral visitors may collect it. In nearly 400 genera in 65 plant… Expand
On optimal nectar foraging by some tropical bees (Hymenoptera: Apidae)
Du butinage optimal de nectar par certaines abeilles tropicales (Hymenoptera: Apidae). Dans des habitats riches du point de vue floristique, on a etudie la concentration en sucres du nectar butine… Expand
Relationship Between Wing Loading, Wingbeat Frequency and Body Mass in Homopterous Insects
Several biophysical properties of members of Aleyrodidae and Aphididae were examined in order to explore how homopterous insects fly. Five species of aphids were found to weigh significantly more… Expand
