Iconic Australasian Tree Fossils Found In South America
2014-01-09 15:06:30

Penn State Today in Australia they call it Kauri, in Asia they call it Dammar, and in South America it does not exist at all unless planted there; but 52 million years ago the giant coniferous evergreen tree known to botanists as Agathis thrived in the Patagonian region of Argentina, according to an international team of paleobotanists, who have found numerous fossilized remains there. "These spectacular fossils reveal that Agathis is old and had a huge range that no one knew about --...

World's Tallest Trees Rely On Limited Seasonal Temperature Variations
2014-01-08 06:55:43

Lee Rannals for redOrbit.com - Your Universe Online A new study published in New Phytologist suggests that temperature could be a growing tree’s best friend. Height is a competitive benefit when it comes to trees, because the taller the tree, the more exposed its leaves are to the sun. As a tree rises above its neighbor to reach more sunlight, it is taking its canopy past the shade that other trees create. Taller trees are able to place leaves at higher light levels while...

Technique advances understanding of a basic concept in graph theory, paralleling advances in edge connectivity Computer scientists are constantly searching for ways to squeeze ever more bandwidth from communications networks. Now a new approach to understanding a basic concept in graph theory, known as "vertex connectivity," could ultimately lead to communications protocols — the rules that govern how digital messages are exchanged — that coax as much bandwidth as possible from...

Successful arborist and owner of a tree company in Boulder, Colo., drew from his own experience to create MapCentrix after finding other software inadequate. Boulder, CO (PRWEB) December 10, 2013 MapCentrix, a fresh new mapping software for those dealing with the care of trees, has been introduced to help them improve the care of the trees they tend. Learn more about MapCentrix or try a demo at http://www.mapcentrix.com. MapCentrix was designed by an arborist, for arborists. Drawing on...

Climate Change Alters Timing Of Spring Growth In Forests
2013-10-30 09:05:58

Technische Universitaet Muenchen In the temperate zones, vegetation follows the change of the seasons. After a winter pause, plants put out new growth in spring. Research has now brought a new correlation to light: The colder the winter, the earlier native plants begin to grow again. Since warmer winters can be expected as the climate changes, the spring development phase for typical forest trees might start later and later – giving an advantage to shrubs and invasive trees that don't...

California Redwoods Reveal Coastal Climate History
2013-10-30 09:05:31

[ Watch the Video: Redwoods Tell The Tale Of Past Climate Change ] redOrbit Staff & Wire Reports - Your Universe Online Giant redwood trees can provide a glimpse into historic coastal climate conditions using a novel method for analyzing the wood’s oxygen and carbon content to detect fog and rainfall in previous seasons, according to a study published in the Journal of Geophysical Research: Biogeosciences. Study leader Jim Johnstone at the University of Washington developed the...

Scientists Use Eucalyptus Trees To Hunt For Gold
2013-10-23 13:35:33

[ Watch the Video: Money Doesn't Grow On Trees...Or Does It? ] Brett Smith for redOrbit.com - Your Universe Online Australian researchers have developed a cutting-edge technique that would make any prospector turn green with envy – the ability to detect gold deposits deep underground based on an analysis of the trees growing above it. According to a new study in Nature Communications, eucalyptus trees are drawing up tiny bits of gold from deep underground and depositing them in...

Live demonstrations of ArborSystems fall Diplodia Tip Blight treatment for pines and conifers using the Wedgle Direct-Inject Tree Treatment System, their new ready-to-use systemic antibiotic direct-inject chemical line for ornamental trees, large woody shrubs and palms and their new Pointle Palm Injection Tip will be on display at the ArborSystems exhibit during the GIE+EXPO October 23 – 25 at the Kentucky Exposition Center in Louisville, Ky. and TCI Expo November 14 - 16 at the...

Trees Might Store More Carbon Than Thought
2013-10-03 07:03:41

DOE/Pacific Northwest National Laboratory Examining a long-lived forest, researchers have found that Black Spruce trees, which dominate the northern forests of North America, succumb about five years after being weakened by environmental stresses. Without rejuvenating fire, the dead trees aren't being replaced by new ones. The result will help researchers better understand how climate change affects the health of forests, and how forests affect the severity of climate change. The study...
