Alpine Glaciers Important For Carbon Cycle 091812
2012-09-18 12:19:01

Alan McStravick for redOrbit.com - Your Universe Online On the surface, the term “carbon cycle” can seem cold and almost prosaic. It´s a term that many of us learned and came to understand in a third-grade science class, with the help of rudimentary illustrations of the sun shining down on the grass that the cow was about to devour for lunch and oversized arrows tracing the flow of energy for us. Like many things we learned in those early classes, it was diluted down to...

Biodiversity Abounds In Madidi National Park
2012-09-14 04:45:24

Alan McStravick for redOrbit.com - Your Universe Online At the IUCN World Conservation Congress, an international gathering of conservationists, held this year in Jeju, South Korea, it was announced that the Madidi National Park, located in the remote Northwestern region of Bolivia, may be the most biologically diverse location on the globe. The Wildlife Conservation Society, in conjunction with the Bolivian Park Service (SERNAP), has published a compendium of species that provide the...

Deforestation Reduces Rainfall
2012-09-06 10:45:47

April Flowers for redOrbit.com - Your Universe Online Tropical rainfall can be significantly affected by deforestation, a new study finds, which can have potentially devastating impacts for people living in and near the Amazon and Congo forests. The research team, a collaboration between the University of Leeds and NERC Centre for Ecology & Hydrology, found that for a majority of the Earth's tropical land surface, air passing over extensive forests produces at least twice as much...

It's All About The Dirt
2012-06-17 03:00:40

[ Watch the Video ] A new study by researchers at BYU, Duke and the USDA finds that soil plays an important role in controlling the planet´s atmospheric future. The researchers set out to find how intact ecosystems are responding to increased levels of carbon dioxide in the atmosphere. The earth´s current atmospheric carbon dioxide is 390 parts per million, up from 260 parts per million at the start of the industrial revolution, and will likely rise to more than 500 parts per...

Proposal follows first continent-wide survey of Antarctic biogeography An international team of scientists have published the first continent-wide assessment of the Antarctic's biogeography, and propose that the landmass should be divided into 15 distinct conservation regions to protect the continent from invasive alien species. The team's findings are published in Diversity and Distributions, while the authors' proposals were outlined today at a lecture to the Antarctic Treaty...

Much of our knowledge about past life has come from the fossil record — but how accurately does that reflect the true history and drivers of biodiversity on Earth? "It's a question that goes back a long way to the time of Darwin, who looked at the fossil record and tried to understand what it tells us about the history of life," says Shanan Peters, an assistant professor of geoscience at the University of Wisconsin—Madison. In fact, the fossil record can tell us a great...

Image 1 - Holm Oaks Will Gain Ground In Northern Forests Due To Climate Change
2011-11-09 04:38:46

Holm oaks and other forests in lowland areas of Mediterranean mountains could expand by up to 350% due to global warming. In contrast, those forest formations that are more adapted to cold and humid conditions, such as beech and Sylvester pines, could shrink by up to 99%. Both scenarios could be quite possible in the 21st century according to a model created to study the effects of climate change on the forests of the Sistema Central and the Sistema Ibérico (Spain). A team led...

Researchers recommend the reworking of global carbon models in Nature The global uptake of carbon by land plants may be up to 45 per cent more than previously thought. This is the conclusion of an international team of scientists, based on the variability of heavy oxygen atoms in the carbon dioxide of the atmosphere driven by the El Niño effect. As the oxygen atoms in carbon dioxide were converted faster than expected during the El Niño years, current...

Image 1 - Bedrock Nitrogen May Help Forests Buffer Climate Change
2011-09-01 10:28:43

  For the first time, researchers at the University of California, Davis, have demonstrated that forest trees have the ability to tap into nitrogen found in rocks, boosting the trees' growth and their ability to pull more carbon dioxide from the atmosphere. Given that carbon dioxide is the most important climate-change gas, the nitrogen in rocks could significantly affect how rapidly the earth will warm in the future, the researchers say. They report their findings in the Sept. 1...

Hispaniolan Pine, Pinus occidentalis
2014-02-26 08:30:03

Hispaniolan pine (Pinus occidentalis) is found largely on the Caribbean island Hispaniola growing on the slopes. Hispaniolan pine forests can be found on the island of Haiti and the Dominican Republic in the mountain range. The Hispaniolan pine can grow in mixed stands of trees with other broadleaf trees at elevations between 2789 and 6890 feet and in pure stands from 6890 feet up to 10,420 feet. These trees are also found in the lowlands growing in acidic soil that is rich in iron and...

Avocado Tree, Persea americana
2014-02-14 16:17:00

Persea americana is a flowering plant that belongs to the Lauraceae family. It is widely known as the Avocado tree. P. americana is a tree that grows up to 66 feet tall. It has alternately arranged leaves that measure about 5 to 10 inches long. Its flowers are tiny and greenish-yellow, measuring .2 to .4 inches in diameter. The tree’s popular, pear shaped green fruit measures 2.8 to 7.9 inches long and weighs between 3.5 and 35 ounces. It contains a single large seed, measuring 2 to 2.5...

Micro Frog, Microbatrachella Capensis
2013-07-16 12:33:22

The Micro Frog (Microbatrachella capensis) is a minute species of frog belonging to the Pyxicephalidae family, in the monotypic genus Microbatrachella. At about .71 inches long, it is one of the smallest regional species. Its color varies from rufous brown with dark mottling, to tan or green, depending on the population. It is native to the south-western Cape area of South Africa, with a single population located on the Cape Flats of Cape Town and a series of populations on the eastern...

Great Basin Shrub Steppe

The Great Basin shrub steppe ecoregion, located within the Deserts and xeric shrublands Biome, incorporates a variety of xeric shrub-steppe sub-ecoregions in the area of the Great Basin in the Western United States. It’s within the North American Desert area, and includes a great deal of Nevada, northeastern and eastern California east of the Sierra Nevada and Cascade Range rain shadows, and some parts of Utah and Idaho. The Great Basin Desert and semi-arid non-desert xeric shrubland...

Mulga Lands
2013-04-19 20:34:07

The Mulga Lands are an interim Australian bioregion out of eastern Australia made up of dry and sandy plains that are scattered with mulga trees. Located in inland New South Wales and Queensland these are level plains with some low hills and infertile sandy soil with a cover of shrubs and grasses with mulga and eucalyptus trees. The region incorporates regions of wetland, the majority of which are only seasonally flooded, these include Lake Numalla and Lake Wyara, the Currawinya Lakes,...
