Plants Mimic Scent Of Pollinating Beetles
2012-04-04 03:33:16

The color and scent of flowers and their perception by pollinator insects are believed to have evolved in the course of mutual adaptation. However, an evolutionary biologist from the University of Zurich has now proved that this is not the case with the arum family at least, which evolved its scent analogously to the pre-existing scents of scarab beetles and thus adapted to the beetles unilaterally. The mutual adaptation between plants and pollinators therefore does not always take place....

Pollen Can Protect Mahogany From Extinction
2012-04-04 03:28:58

New research from the University of Adelaide could help protect one of the world's most globally threatened tree species - the big leaf mahogany - from extinction. Big leaf mahogany (Swietenia macrophylla) is the most prized mahogany timber around the world. It is at risk of extinction in its native habitats because of the timber trade, particularly in Central and South America. To better understand how such a threatened species can be brought back from the brink of extinction,...

For more than a century, Vincent Van Gogh's series of paintings depicting overly-bushy sunflowers were thought to be the result of his alleged mental illness at work, but now could actually be realistic impressions of a genetic mutation seen in some strains of the flowers, according to a new study. Most typical sunflowers have a brown, seed-filled middle and a single ring of yellow petals. But some seem overgrown with double rows of petals -- like the "Teddy Bear" variety -- and others...

In addition to being among his most vibrant and celebrated works, Vincent van Gogh's series of sunflower paintings also depict a mutation whose genetic basis has, until now, been a mystery In addition to being among his most vibrant and celebrated works, Vincent van Gogh's series of sunflower paintings also depict a mutation whose genetic basis has, until now, been a mystery. In a study published in PLoS Genetics, a team of University of Georgia scientists reveal the mutation behind the...

New research reveals Artemisia tridentata seeds can form a persistent seed bank, ensuring its survival in an invasive, fire-prone system Big sagebrush (Artemisia tridentata) is a key foundational species in an ecosystem that is threatened by invasion of cheatgrass and the subsequent increase in fire frequency. Critical to the conservation, reestablishment, and restoration of the sagebrush steppe ecosystem (which comprises 63 million hectares of the Great Basin of North America) is...

Russian Researchers Claim They’ve Regenerated 32,000 Year-Old Plant
2012-02-22 05:43:22

According to a recent report in the New York Times, Russian scientists have successfully generating a living plant (Silene stenophylla) from the fruit of a species that went extinct in the last ice age some 32,000 years ago. The paper reported Monday that the plant´s fruit was apparently stowed away by an arctic ground squirrel in the wastelands of northeastern Siberia. Hidden beneath the permafrost of the frozen tundra for some 32 millennia, Russian researches recovered the almost...

Pollen recovered in a 2,500-year-old garden helps reconstruct a paradise of exotic plants, say TAU researchers Researchers have long been fascinated by the secrets of Ramat Rahel, located on a hilltop above modern-day Jerusalem. The site of the only known palace dating back to the kingdom of Biblical Judah, digs have also revealed a luxurious ancient garden. Since excavators discovered the garden with its advanced irrigation system, they could only imagine what the original garden might...

According to long-term studies in Amazonia, Africa and central America, the worlds largest trees are dying off due to the encroachment of man. The roads and villages that men build fragment forests while the trees are battling against severe droughts, pests and diseases. The studies have shown that the trees have adapted well to centuries of storms, pests and short-term climactic extremes, reports the Guardian. But these large trees are counterintuitively more vulnerable than other trees...

Fungi-filled Forests Critical For Endangered Orchids
2012-01-25 04:15:43

Older forests with just the right fungi may be secret to saving vulnerable plants When it comes to conserving the world's orchids, not all forests are equal. In a paper to be published Jan. 25 in the journal Molecular Ecology, Smithsonian ecologists revealed that an orchid's fate hinges on two factors: a forest's age and its fungi. Roughly 10 percent of all plant species are orchids, making them the largest plant family on Earth. But habitat loss has rendered many threatened or...

Kelp forests are areas that are underwater with a high density of kelp. They’re recognized as one of the most dynamic and productive ecosystems on Earth. Smaller regions of anchored kelp are known as kelp beds. Kelp forests can be found worldwide throughout polar and temperate coastal oceans. In the year 2007, kelp forests were discovered in tropical waters near Ecuador as well. While they are physically formed by brown macroalgae of the order Laminariales, kelp forests offer a unique...

The Lily of the Nile or Calla Lily (Zantedeschia aethiopica) is a species of plant native to southern Africa in Lesotho, South Africa, and Swaziland. It has been introduced to Western Australia where it occurs in high periodical water tables and sandy soil. Several hybrids have been established and introduced to other areas around the world. Some hybrids are more suited to cooler climates. One hybrid, Crowborough, grows better in the British Isles and the northwestern United States than it...
