Ups And Downs Of Early Atmospheric Oxygen
2014-02-20 10:41:29

Iqbal Pittalwala - University of California - Riverside UC Riverside research team challenges conventional view of a simple two-step rise in early oxygen on Earth; study suggests instead dynamic oxygen concentrations that rose and fell over billions of years A team of biogeochemists at the University of California, Riverside, give us a nontraditional way of thinking about the earliest accumulation of oxygen in the atmosphere, arguably the most important biological event in Earth...

Fungi Plays Role As Rainforest 'Diversity Police'
2014-01-23 12:54:43

University of Oxford The Oxford University-led research found that fungi regulate diversity in rainforests by making dominant species victims of their own success. Fungi spread quickly between closely-packed plants of the same species, preventing them from dominating and enabling a wider range of species to flourish. "In the plant world, close relatives make bad neighbours," said Dr Owen Lewis of Oxford University's Department of Zoology, who led the study. "Seedlings growing near...

Source Of Galapagos Volcano
2014-01-21 14:35:32

Brett Smith for redOrbit.com - Your Universe Online A new analysis from a team of American researchers has found the volcanic plume that created the Galapagos Islands isn’t where models have projected it. The study team said their findings could also explain volcanic activity around the islands. According to the study, which was published on Sunday the journal Nature Geoscience, the Galapagos plume is at a depth of 155 miles, approximately 100 miles southeast of the westernmost island...

East Antarctica Is Pushing Around Its Softer-Mantled Western Half
2013-12-12 07:51:20

April Flowers for redOrbit.com - Your Universe Online It's easy to know what to do when half-siblings are pushing each other around, but what do you do about half-continents? A team of researchers, led by Ohio State University, have discovered that East Antarctica is pushing West Antarctica around. West Antarctica is losing weight in the form of billions of tons of ice per year, making its mantle rock softer. This rock is being nudged westward by the harder mantle beneath East...

Minerals Were Scarce When Life First Formed On Earth: Study
2013-11-26 08:05:20

redOrbit Staff & Wire Reports - Your Universe Online Just eight percent of the nearly 5,000 different types of minerals currently found on Earth were present on or near the planet’s surface when life first originated, according to new research published in the latest edition of the American Journal of Science. According to researchers from the Carnegie Institution for Science, life came about as a result of natural processes that took advantage of raw materials available during...

The special issue of Rangelands presents articles exploring strategic management of ever-changing environments. Researchers should seek to developing creative approaches to grazing management that allow flexibility over time. Lawrence, Kansas (PRWEB) October 29, 2013 Rangelands - Grazing management that extends the vitality of rangelands and ensures the best food sources for livestock is not a new concept. However, recognizing that they are not “rules of thumb” that can be applied...

Oxygen Levels Prior To The Cambrian Explosion May Have Been Enough For Life
2013-10-19 05:00:29

redOrbit Staff & Wire Reports - Your Universe Online An international team of researchers has discovered that the Earth’s oxygen content 2.1 billion years ago was the same as it was during the so-called Cambrian explosion that occurred approximately 542 years ago and resulted in the appearance of most major animal phyla. Given the fact that oxygen and the development of advanced life are inextricably linked, this led the study authors to ponder the sudden emergence of living...

Rainforests
2013-04-19 19:33:20

Rainforests are forests that are characterized by high levels of rainfall, with definitions based on a minimum usual annual rainfall of about 68 to 78 inches. The monsoon trough, or otherwise known as the intertropical convergence zone, holds an important role in producing the climatic conditions that are essential for the Earth’s tropical rainforests. About 40 to 75 percent of all biotic species are native to the rainforests. It’s been estimated that there might be many millions of...

Desertification
2013-04-02 09:46:56

Desertification is a form of land degradation in which a comparatively dry land area becomes more and more arid, normally losing its bodies of water along with its wildlife and vegetation. This is a result of a variety of factors, such as climate change and human activities. Desertification is an important global, ecological, and environmental issue. There is substantial controversy over the proper definition of the term “desertification”. The most broadly accepted of these is that of...

Geologic Clock With Events And Periods

The Paleoproterozoic is the first of three subdivisions of the Proterozoic Eon (occurring from 2.5 billion to 1.6 billion years ago (Ga). This period is marked by the first stabilization of the continents, and also when cyanobacteria--a type of bacteria that uses biochemical processes of photosynthesis to produce oxygen--evolved. Experts have found paleontological evidence that during at least part of the Paleoproterozoic era, about 1.8 Ga, the earth year was about 450 days long, with days...

Geologic Clock With Events And Periods

The Archean (formerly Archaeozoic) is a geologic eon between the Hadean and Proterozoic eons. The Archean Eon begins at roughly 3.8 billion years ago (Ga) and ends at about 2.5 Ga. But unlike all other geological ages, which are based on stratigraphy, The Archean eon is defined chronometrically. The lower boundary of 3.8 Ga has also not been officially recognized by the International Commission on Stratigraphy. The name Archean is derived from the ancient Greek (Arkhe), meaning...

The Hadean is the unofficial geological period of time that lies just before the Archean time period. The Hadean began with the formation of the Earth roughly 4.5 billion years ago (Ga) and ended about 3.8 Ga; the latter date varies according to different sources. Hadean is derived from Hades, Greek for “underworld,” referring to the hellish conditions on the planet at the time. The term was coined in 1972 by geologist Preston Cloud. The period was later classified as the “Priscoan...
