Certain Fruits Can Fight Against Obesity
2012-06-19 08:51:04

Connie K. Ho for redOrbit.com Walking in the aisle of a produce section of a supermarket, you´ll be bombarded by a variety of fragrant smells and bright colors. With so many choices these days, it can be quite difficult to pick out the best healthy fruits and veggies. Luckily, a new study points to fruits that have beneficial qualities. Texas AgriLife Research recently discovered that peaches, plums, and nectarines have bioactive compounds that can possibly stave off obesity-related...

Plant Tricks Mouse Into Spitting Out Its Seeds
2012-06-16 05:04:27

[ Watch the Video ] Brett Smith for redOrbit.com A plant in the Israeli desert has developed a ℠toxic mustard bomb´ which causes the spiny mouse that eats its berries to spit out the seeds like a child munching on watermelon. Researchers found that enzymes within the seeds of the sweet mignonette berries activate toxic substances in its pulp, which would otherwise go unnoticed, according to a new study published online in the journal Current Biology. When an unknowing...

Inflorescence architecture of Babiana ringens may have evolved in response to selective pressures from both herbivores and pollinators Floral displays, such as the color, shape, size, and arrangement of flowers, are typically thought to have evolved primarily in response to selection by pollinators–for animal-pollinated species, being able to attract animal vectors is vital to an individual plant's reproductive success. But can herbivores also exert similarly strong selective forces...

What Makes Flowers More Attractive To Bees?
2012-05-29 05:44:38

As gardeners get busy filling tubs and borders with colorful bedding plants, scientists at the Universities of Cambridge and Bristol have discovered more about what makes flowers attractive to bees rather than humans. Published today in the British Ecological Society's journal Functional Ecology, their research reveals that Velcro-like cells on plant petals play a crucial role in helping bees grip flowers — especially when the wind gets up. The study focuses on special cells found on...

UCLA life scientists have discovered new laws that determine the construction of leaf vein systems as leaves grow and evolve. These easy-to-apply mathematical rules can now be used to better predict the climates of the past using the fossil record. The research, published May 15 in the journal Nature Communications, has a range of fundamental implications for global ecology and allows researchers to estimate original leaf sizes from just a fragment of a leaf. This will improve scientists'...

How Flowers Pollinate With Precision
2012-05-17 11:25:35

Next Mother's Day, say it with an evolved model of logistical efficiency – a flower. A new discovery about how nature's icons of romance manage the distribution of sperm among female gametes with industrial precision helps explain why the delicate beauties have reproduced prolifically enough to dominate the earth. In pollination, hundreds of sperm-carrying pollen grains stick to the stigma suspended in the middle of a flower and quickly grow a tube down a long shaft called a style...

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...

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...
