Change In Critical Grasslands Diminishing Cattle Production

Sandy Leander, ASU School of Life Sciences Half of the Earth’s land mass is made up of rangelands, which include grasslands and savannas, yet they are being transformed at an alarming rate. Woody plants, such as trees and shrubs, are moving...

redOrbit Staff & Wire Reports - Your Universe Online Over four billion years ago, giant asteroid impacts collided with the Earth’s surface and gave the planet a facelift of sorts – mixing, burying and melting the landscape, according to a new terrestrial bombardment model devised by an international team of researchers from various academic and government institutions. The new model was based on existing lunar and terrestrial data, and according to the authors of a new paper...

More People Means More Plant Growth

Kathryn Hansen, NASA Ecologist Thomas Mueller uses satellite data to study how the patterns of plant growth relate to the movement of caribou and gazelle. The research sparked an idea: Would the footprint of human activity show up in the data? Mueller, of the University of Maryland in College Park (now at the Biodiversity and Climate Research Center in Frankfurt) teamed up with university and NASA colleagues to find out. Their new analysis shows that on a global scale, the presence of...

An article featured in Rangelands discusses the practice of patch-burning and compares this technique to that of more traditional methods. However, after conducting a 3-year study, the authors concluded that there was no statistical difference in the cattles' body condition score (BCS) when measuring the patch-burning method against the traditional grazing methods. Lawrence, Kansas (PRWEB) June 16, 2014 To keep order on rangelands, range managers must carefully monitor the grazing...

STEENBERGEN, The Netherlands, May 21, 2014 /PRNewswire/ -- A new Groasis invention, a biodegradable version of the proven successful Waterboxx, is the answer against desertification. The Groasis Greenboxx, made of recycled paper, is an environmentally friendly development of the Waterboxx. The Groasis Greenboxx can be used to plant one tree in a desert without using irrigation. It saves up to 97% of water while planting. After a year the Groasis Greenboxx degrades and...

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...

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...
