Nature's Mathematical Formula For Survival
2012-05-14 09:36:55

[ Watch the Video ] Geometric patterns link structure to function in leaves The structure and delivery of nutrients is provided by the Vascular system in the leaf. With the use of fluorescent dye and time-lapse photography, details of nature's mathematical formula for survival begin to emerge. Mother Nature is tough to beat when it comes to optimizing form with function. Marcelo Magnasco, a mathematical physicist at Rockefeller University in New York, says "When looking at the...

The Absence Of Elephants And Rhinoceroses Reduces Biodiversity In Tropical Forests
2012-05-11 08:52:07

The progressive disappearance of seed-dispersing animals like elephants and rhinoceroses puts the structural integrity and biodiversity of the tropical forest of South-East Asia at risk. With the help of Spanish researchers, an international team of experts has confirmed that not even herbivores like tapirs can replace them. "Megaherbivores act as the 'gardeners' of humid tropical forests: They are vital to forest regeneration and maintain its structure and biodiversity", as was explained...

Birds Cultivate Decorative Plants To Attract Mates
2012-04-23 10:35:51

An international team of scientists has uncovered the first evidence of a non-human species cultivating plants for use other than as food. Instead, bowerbirds propagate fruits used as decorations in their sexual displays. The researchers discovered male bowerbirds had unusually high numbers of fruit-bearing plants growing around their bowers, and used these fruits in order to attract females. Published today (24 April), in Current Biology the research was carried out by the Universities of...

When unproductive plants were given the working protein, their flowering time was restored Flowering is the most crucial act that plants undergo, as the fruits of such labor include crops on which the world depends, and seeds from which the next generation grows. While classic experiments have demonstrated that plants are able to adjust the timing of their flowering in response to environmental conditions, such as light, temperature and the availability of nutrients, very little has...

Flowering is the most crucial act that plants undergo, as the fruits of such labor include crops on which the world depends, and seeds from which the next generation grows. While classic experiments have demonstrated that plants are able to adjust the timing of their flowering in response to environmental conditions, such as light, temperature and the availability of nutrients, very little has been known about what exactly triggers plants to make flowers instead of leaves, under various...

Seed size is controlled by small RNA molecules inherited from a plant's mother, a discovery from scientists at The University of Texas at Austin that has implications for agriculture and understanding plant evolution. "Crop seeds provide nearly 70 to 80 percent of calories and 60 to 70 percent of all proteins consumed by the human population," said Z. Jeff Chen, the D.J. Sibley Centennial Professor in Plant Molecular Genetics at The University of Texas at Austin. "Seed production is...

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,...

Persian cyclamen, Cyclamen persicum
2014-01-08 20:39:58

Cyclamen persicum is a flowering, herbaceous plant from the Myrsinaceae family. It is commonly referred to as the Persian cyclamen. C. persicum is a tuberous plant. A tuber is a modified plant structure that is enlarged to store nutrients. The flowers and leaves come from buds at the top of the tuber. Roots emerge from the sides and bottom. Wild specimens have heart-shaped leaves that grow as long as 6 inches. They are usually green in color, with a light green marbling effect on the...

Kelp Forest
2013-04-19 19:29:03

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...

The Coco (Fagara coco or Zanthoxylum coco) is a species of evergreen tree native to Argentina and Bolivia. It grows in wild, mostly hilly, spinniferous (thorny or spiny) forests. Its habitat is found along the hilly forest of the Sierra Pampeana. This plant is found either in small isolated groups or standing alone. Other common names for this plant are cochucho or "smelly sauco". The Coco is a medium sized tree ranging from 20 to 26.25 feet tall. Its foliage is abundant and has paired...
