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...

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'...

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...

By Stuart Wolpert, UCLA The size of leaves can vary by a factor of 1,000 across plant species, but until now, the reason why has remained a mystery. A new study by an international team of scientists led by UCLA life scientists goes a long way toward solving it. In research federally funded by the National Science Foundation, the biologists found that smaller leaves are structurally and physiologically better adapted to dry soil because of their distinct vein systems. The research will be...

Vegetation in an area may determine its usable water supply, ecologists find Ecologists have discovered that timber plantations in Hawaii use more than twice the amount of water to grow as native forests use. Especially for island ecosystems, these findings suggest that land management decisions can place ecosystems "“ and the people who depend on them "“ at high risk for water shortages. "Scientists used to think that forests in same environments use water in the same way," says...


Word of the Day
ween
  • To think; to imagine; to fancy.
  • To be of opinion; have the notion; think; imagine; suppose.
The word 'ween' comes from Middle English wene, from Old English wēn, wēna ("hope, weening, expectation"), from Proto-Germanic *wēniz, *wēnōn (“hope, expectation”), from Proto-Indo-European *wen- (“to strive, love, want, reach, win”).
