Global warming threatens state's quality of life
...igher altitudes and more northerly locations. The redwood forests of northern California could be endangered as well as the kelp forests of the southern part of the state. The numbers of disease-carrying rodents -- such as hantavirus carrying mice -- could go up. Changes are already occurring in the ocean...UC Davis expert identifies oak-tree killer and warns public to use caution
...uch of the California coastline, especially in the redwood forests of the foggy coast ranges. It cannot be seen unaided but under a microscope, colonies of the fungus look like clusters of cotton fibers, he said. Those little creatures are highly fecund, he found; a single organism kept at 59 to 68 degrees F......ng relationship as for animals. For example, as a redwood tree grows in size over centuries, its rate of growth gradually slows down according to this very precise mathematical relationship. This relationship was first predicted by Enquist, Geoffrey B.

...ifornia's coast oak ecosystems. It also threatens redwood and Douglas fir forests on the West coast, and red and pin oak forests in the East. Tyler's research group will provide a genetic map of the P. sojae genome that will be used to assemble the raw DNA sequence data to be produced at the DOE Joint Geno...Mole-rat Methuselahs push evolutionary theory of aging
...s, humans regularly live eight to nine decades and redwood trees for millennia. "Whatever kind of organism it is, it's going to senesce," says Paul Sherman, a professor of neurobiology and behavior at Cornell University. "Of course, good food and exercise, proper medical care and avoiding risky behaviors ma...Virginia's champion trees make history
..."For example," explained Kirwan, "the new champion redwood nominated by Joe Foreman of Norfolk a year ago scored 270 total points, beating the former three co-champions by more than 45 points. Another tree, a new champion black oak, nominated by Charlie Knoeller, from Westmoreland County, scored 469 total po...Leaf fall in ancient polar forests still a mystery
...pothesis was correct. They looked at gingko, dawn redwood and bald cypress, all deciduous trees that are considered living fossils because they have existed much as they are since there were polar forests. Also tested were two living fossil evergreens, sequoia and southern beech. In Sheffield, the trees g...How lice and bird feathers stick together
...ephone poles, then you might have trouble climbing redwood trees or a clothesline pole," Clayton explains. Bush tested that idea by cutting a small, square piece of feather from each wing of several rock pigeons. On one wing, she used fabric glue to transplant a piece of feather from another rock pigeon.

However, it poses a large threat to Virginia oak trees and other Eastern Seaboard plant species that have proven highly susceptible to the pathogen in greenhouse tests. Tyler identified the Virginia highland...
