More carbon dioxide is released from residential lawns than corn fields according to a new study. And much of the difference can likely be attributed to soil temperature. The data, from researchers at Elizabethtown College, suggest that urban heat islands may be working at smaller scales than previously thought. These findings provide a better understanding of the changes that occur when agricultural lands undergo development and urbanization to support growing urban populations. David...

A new global-scale modeling study that takes into account nitrogen — a key nutrient for plants — estimates that carbon emissions from human activities on land were 40 percent higher in the 1990s than in studies that did not account for nitrogen. Researchers at the University of Illinois at Urbana-Champaign and the University of Bristol Cabot Institute published their findings in the journal Global Change Biology. The findings will be a part of the upcoming Fifth Assessment...

Atmospheric Nitrogen Levels Have Remained Stable Over Past 500 Years Despite Widespread Emissions

Brett Smith for redOrbit.com - Your Universe Online Despite widespread use of fertilizers and nitrogen emissions by industrial processes, the amount of atmospheric nitrogen has remained consistent over the past 500 years, according to a new study in Nature. "People have been really interested in nitrogen in current times because it's a major pollutant," said study co-author Kendra McLauchlan, an assistant professor of geography at Kansas State University. "Humans are producing a lot...

Around half of Cambodia's tropical flooded grasslands have been lost in just 10 years according to new research from the University of East Anglia. The seasonally flooded grasslands around the Tonle Sap, Southeast Asia´s largest freshwater lake, are of great importance for biodiversity and a refuge for 11 globally-threatened bird species. They are also a vital fishing, grazing, and traditional rice farming resource for around 1.1 million people. Research published today in the...

New Cryptic Spider Species From Africa

Pensoft Publishers A revision of the genus Copa offers a peculiar insight into spider biogeography in the Afrotropical Region The species from the genus Copa are very common spiders found in the leaf litter of various habitats. Being predominantly ground-living, they occur widely in savanna woodlands but also occasionally in forests, where they are well camouflaged. They usually share the litter microhabitats with several other species of the family Corinnidae. The spiders from this...

Alligator Relative Traveled Across Ancient Land Bridge

April Flowers for redOrbit.com - Your Universe Online The Isthmus of Panama uplifted 2.6 million years ago to form a land bridge connecting North and South America. This bridge has long been thought to be the crucial step in the interchange of animals between the Americas. Armadillos and giant sloths moved up into North America and ancient relatives of modern horses, rabbits, foxes, pigs, cats, dogs and elephants moved down into South America. A new study from the University of Florida...

Mangroves And Swamp Forests Important For Endangered Species
2013-03-01 05:50:19

April Flowers for redOrbit.com - Your Universe Online Facing relentless human encroachment, some endangered primates and large cats will seek sanctuary in the sultry thickets of mangrove and peat swamp forests. These are not inviting places. Instead they are harsh coastal biomes with thick vegetation such as clusters of salt-loving mangrove trees and highly acidic peat soil composed of the waterlogged remains of partially decomposed leaves and wood. Because of these conditions, swamp...
