Flower Blasts Pollen At Birds

Cell Press A small tree or shrub found in mountainous Central and South American rainforests has a most unusual relationship with the birds that pollinate its flowers, according to a study reported in the Cell Press journal Current Biology on...

Betrayal By Bees Could Have Huge Impact On Plant Reproduction

April Flowers for redOrbit.com - Your Universe Online A new study led by Emory University finds removing even one species of bumblebee from an ecosystem has a swift and clear impact: the floral "sweethearts" of that species produce significantly fewer seeds. The research team focused on the interactions between bumblebees and larkspur wildflowers in Colorado's Rocky Mountains. The findings, to be published by the Proceedings of the National Academy of Sciences, reveal how reduced...

New research has shown that certain Australian native flowers have shifted away from using insects as pollinators and evolved their flower color to the red hues favored by birds. In a study published in New Phytologist, biologists from Monash University and RMIT University have shown for the first time that Australian native flowers exclusively pollinated by birds have evolved color spectral signatures that are best discriminated by those birds. Dr Adrian Dyer of Monash and RMIT said...

The Pollination Game Is Greatly Affected By A Changing Climate
2013-03-01 12:34:02

Brett Smith for redOrbit.com - Your Universe Online The relationships among species change over time as shifts in an ecosystem begin to affect the organisms living in them. Climate change has placed a new emphasis on studying these shifting relationships and a team of biologists from the Midwest sifted through historical scientific logs to find that the plant-pollinator relationships in their area have been significantly altered over the past 120 years. Working out of Washington...

Electric Flowers Help Bees Pick Up Pollen
2013-02-22 11:25:13

Brett Smith for redOrbit.com - Your Universe Online Previous research has shown that bees build up an electrical charge as they buzz through the air, but a new study from the University of Bristol in the U.K. has shown that the bees are able to use this charge to interact with nectar-bearing flowers. According to a summary of the study recently published in the journal Science, the British scientists showed that flowers actually modify their own electrical fields to attract the flying...

How flowers have evolved particular colors, shapes and scents to attract pollinators has long fascinated ecologists. Now, using artificial flowers and high-speed video, researchers have gained intriguing insights into the intimate relationship between hummingbirds and the flowers they pollinate. The study, published in the British Ecological Society's journal Functional Ecology, is the first to measure how much energy hummingbirds use while hovering to feed from flowers of different...

Reproductive assurance in a self-compatible, annual, monocarpic herb, Centaurium erythraea In plants that rely on animals for pollination, the number of seeds they produce, or their relative fitness, is influenced by pollinator visits and the successful deposition of pollen. The number of visits a plant may receive depends partly on pollinator density as well as on conspecific plant density. But what if a plant happens to grow in a population that is small or has very few pollinators...

Phylogeny constrains floral scent rewards in a specialized bee-pollinated group of oil-secreting orchids Bees, bats, and moths all follow their noses in search of food from flowers. Plants that rely on such animals for pollination often produce particular chemical scents that attract specific pollinators. However, the ability to produce certain chemicals is also determined by a plant's genetics, or phylogenetic history, which can potentially limit its ability to respond to pollinator...

Across the western Cape of South Africa can be found small plants in the Iris family called Babiana. Flitting between them are sunbirds, small colourful birds like the African version of hummingbirds, that drink the nectar of flowers and in doing so pollinate them. New research to be published early next year in a special edition on plant mating in the Annals of Botany (http://j.mp/pRSzzC) by De Waal, Anderson and Barrett shows that while birds are important for plant reproduction, when it...

Scientists have discovered why orchids are one of the most successful groups of flowering plants - it is all down to their relationships with the bees that pollinate them and the fungi that nourish them. The study, published tomorrow in the American Naturalist, is the culmination of a ten-year research project in South Africa involving researchers from Imperial College London, the Royal Botanic Gardens, Kew, and other international institutions. The orchid family is one of the largest groups...

Pollinators interact with their landscapes to affect the genetic structure of 3 Penstemon species in the Great Basin Do mountain tops act as sky islands for species that live at high elevations? Are plant populations on these mountain tops isolated from one another because the valleys between them act as barriers, or can pollinators act as bridges allowing genes to flow among distant populations? Dr. Andrea Kramer and colleagues from the Chicago Botanic Garden and the University of Illinois...
