...frost starts coming later, though, she says, they can't un-evolve overnight. "The current forests won't immediately start growing taller and stronger," she says. Eventually, the evolutionary process will catch up, as new seedlings without the frost response take over. "In principle, however," says Kuparinen, "this process will take a long time. The rate of evolution is slower than the rate at which climate will change." The forests would thus get no benefit, remaining stunted until seedlings without early dormancy genes can take root and take over...
Climate change will, moreover, lead to different effects in different parts of the world. "In northern areas," says Lobell, "you'll see an expansion of the growing season" - which, if the Finnish study is correct, won't necessarily help forests, but could be good for crops, since you can deliberately plant seeds that are suited to long summers. But in arid parts of the tropics, he says, where plant growth is limited by the availability of water, more frequent droughts could make things worse. "Large parts of the world," says Field, "are already at the warm edge of where things...
...principle, plants can shift their ranges as the climate changes. But as Kuparinen and her colleagues are only the most recent to note, that shifting won't necessarily keep pace with a shifting climate. "In general," says Field, "we don't have very good understanding of the mechanisms that allow plants to move around on the landscape." Current estimates, he says, are based largely on studies of ancient ecologies. "But our models are mostly not validated for the modern, human-dominated environment...
...going to check on the response form, tell them you’ve accepted and will be a student in the fall. No one wants to hear you rattle off the Ivies you’re debating over, so humor us. It will make us happy, and we won't know if you’re lying anyway...
...strengthened. He comes out not only vindicated but looking like a statesman," says Anita Isaacs, a Guatemala expert at Haverford College who has testified before the U.S. Congress on peace building in the country. Colom, the first left-of-center President to be elected in more than 50 years, won office with the support of indigenous, rural Mayans and vowed to help alleviate widespread poverty in the countryside with programs that have angered the nation's oligarchy, including cash rewards to poor parents who send their children to school regularly...
