A redwood tree discovered in a remote California forest has turned out to be the world’s tallest tree, edging out one nearby that had beenthe previous titleholder, a botanist said Friday.Humboldt State University Professor Steve Sillett told Reuters the record-setting tree, named Hyperion, is 379.1 feet tall, besting the previous record holder, the 370.5-foot-tall Stratosphere Giant.Researchers exploring remote and rugged terrain this summer in the Redwood National and State Parks along California’s northernmost coast also discovered two other redwoods taller than the Stratosphere Giant, suggesting there had been many more massive ancient redwoods in the area, Sillett said.
those tallertrees may have fallen to loggers, while the remaining ones
were saved by a logging ban when the Redwood National Park was expanded
in 1978, Sillett said.
Officials would not
pinpoint the exact locations of the trees out of concern that too many
visitors could damage the delicate ecology of the mild, foggy slopes
where the trees live
“What we have today is a few small remnants that suggest what these trees are capable of doing,” Sillett said.
The Jurupa Oak is so old that it was alive during the last Ice Age and before human agriculture.Unlike most plants the ancient oak reproduces by cloning itself after being burned in wildfires, this way it continues to live onwards like a Phoenix rising from the ashes and expands slowly outwardseach time it happens.
Scientists found the oak in an unlikely habitat: dry and hot rocky hills and found that it survives against the odds like an insane sci-fi villain: by cloning itself to continue life after being burned to death.
Submitted by Artemis: A super volcano is the most destructive natural force on earth. Super volcanoes produce the largest and most voluminous kinds of eruptions ever recorded throughout earth history. Most super volcanoes are what volcanologists call caldera volcanoes. Caldera volcanoes are formed after magma has been erupted and the volcano collapses into the voided chamber.The largest known super volcano is the Siberian Traps in Russia, which had the largest volcanic event in the last 500 million years. The Siberian Traps eruption, which lasted over a million years has been blamed for the Permian-Triassic extinction event. This extinction event occurred 252 million years ago, when 90% ofall marine life and 70% of all other life became extinct.What most do not realize is the number of these sleeping giants that exist.
When someone in the United States hears the word super volcano they think "Yellowstone", but Yellowstone isn't the only monster that exists. Some caldera volcanoes located in North America are Yellowstone (WY), Crater Lake (OR), Long Valley (CA), Sturgeon Lake (Ontario), Valle Grande (NM). Some of the biggest caldera volcanoes from around the world are Krakotoa (Indonesia), Tambora (Indonesia), Toba (Sumatra), Taupo (New Zealand) and the Siberian Traps in Russia. There are over 138 caldera volcanoes in the world, whose crater exceeds 5 miles in diameter, 40 of which are super volcanoes. Evidence shows that when super volcanoes erupt it effects our climate andthe environment for many years after. The Toba eruption 74,000 years ago, and the 3 Yellowstone eruptions 2.1 million, 1.3 million and 640,000 years ago have been blamed for causing earths past ice ages.Here's a good illustration of the eruptive capacity of a super volcano. Mount St. Helens 1980 eruption ejected 1.2 cubic kilometers of material, enough to fill a large sports stadium 1,569 times. The St. Helens eruption is very small compared to historic super eruptions.
Next time you purchase white button mushrooms at the grocery store, just remember, they may be cute and bite-size but they have a relative out west that occupies some 2,384 acres (965 hectares) of soil in Oregon"s Blue Mountains. Put another way, this humongous fungus would encompass 1,665 football fields, or nearly four square miles (10 square kilometers) of turf. The discovery of this giant Armillaria ostoyae in 1998 heralded a new record holder for the title of the world"s largest known organism, believed by most to be the 110-foot- (33.5-meter-) long, 200-ton blue whale. Based on its current growth rate, the fungus is estimated to be 2,400 years old but could be as ancient as8,650 years, which would earn it a place among the oldest living organisms as well.
A team of forestry scientists discovered the giant after setting out to map the population of this pathogenic fungus in eastern Oregon. The team paired fungal samples in petri dishes to see if they fused, a sign that they were from the same genetic individual, and used DNA fingerprinting to determine where one individual fungus ended. This one, A. ostoyae, causes Armillaria root disease, which kills swaths of conifers in many parts of the U.S. and Canada. The fungus primarily grows along tree roots via hyphae, fine filaments that mat together and excrete digestive enzymes. But Armillaria has the unique ability to extend rhizomorphs, flat shoestringlike structures, that bridge gaps between food sources and expandthe fungus"s sweeping perimeter ever more. A combination of good genes and a stable environment has allowed this particularly ginormous fungus to continue its creeping existence over the past millennia. "These are very strange organisms to our anthropocentric way of thinking," says biochemist Myron Smith of Carleton University in Ottawa, Ontario. An Armillaria individual consists of a network of hyphae, he explains. "Collectively, this network is called the mycelium and is of an indefinite shape and size.
