UCLA life scientists, working with colleagues in China, have discovered a new method to quickly assess plants' drought tolerance. The method works for many diverse species growing around the world. The research, published in the journal Methods in Ecology and Evolution, may revolutionize the ability to survey plant species for their ability to withstand drought, said senior author Lawren Sack, a UCLA professor of ecology and evolutionary biology. "This method can be applied rapidly and...

University of Adelaide researchers have discovered that recent climate change is causing leaves of some Australian plants to narrow in size. The study, which is the first of its kind in the world, highlights that plant species are already responding to changes in climate. The results are published online today in the Royal Society journal Biology Letters. Researchers analysed leaves from herbarium specimens of Narrow-leaf Hopbush (Dodonaea viscosa subsp. angustissima) dating from the...

[ Watch the Video ] redOrbit Staff & Wire Reports - Your Universe Online An international team of scientists has revealed that the ancestors of modern humans had an unusual diet -- one which may have contributed to their ultimate downfall, according to various reports published Wednesday. According to Thomas H. Maugh II of the Los Angeles Times, researchers led by the Max Planck Institute of Evolutionary Anthropology in Leipzig, Germany have discovered that Australopithecus...

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'...

Although scientists have made significant advances in understanding how plants elongate at high temperature, little is known of the physiological consequences of this response. To investigate these consequences, the researchers, led by Dr Kerry Franklin and Professor Alistair Hetherington in Bristol's School of Biological Sciences, studied thale cress (Arabidopsis thaliana), a small flowering plant which is a popular model species in plant biology and genetics. When grown at higher...

Nature's Mathematical Formula For Survival

[ 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...

RUB biologists decipher the function of the metal-binding molecule nicotianamine In order to survive, plants should take up neither too many nor too few minerals from the soil. New insights into how they operate this critical balance have now been published by biologists at the Ruhr-Universität in a series of three papers in the journal The Plant Cell. The researchers discovered novel functions of the metal-binding molecule nicotianamine. "The results are important for...

New research by UCLA life scientists could lead to predictions of which plant species will escape extinction from climate change. Droughts are worsening around the world, posing a great challenge to plants in all ecosystems, said Lawren Sack, a UCLA professor of ecology and evolutionary biology and senior author of the research. Scientists have debated for more than a century how to predict which species are most vulnerable. Sack and two members of his laboratory have made a fundamental...

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,...
