Alpine Glaciers Important For Carbon Cycle 091812

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...

Predator-Created Domino Effect Leads To Ecosystem Changes
2012-06-17 05:42:51

Creatures that are feeling the pressure from the presence of predators are known to alter their diets, thus having a noteworthy impact on their habitats, claims new research published in the journal Science. According to the National Science Foundation (NSF), researchers from Yale University and the Hebrew University of Jerusalem teamed up to study changes in the types of plant life consumed by grasshoppers under different circumstances. Ordinarily, grasshoppers eat nitrogen-rich grass,...

The Faculty of Biosciences at the University of Helsinki includes a project focusing on the ten major rivers in the world. Academy Research Fellow Anssi Vähätalo's group addresses the journey of riverine organic to the oceans and in particular the photochemical decomposition of organic carbon caused by sunlight. The research project sheds new light on the mechanisms of the carbon cycle on the global scale and it enhances understanding of the links between continents and oceans....

U.S. scientists say they've determined earthworms can change the chemical nature of the carbon in North American forest litter and soils. Purdue University scientists, along with researchers from the Smithsonian Institution and Johns Hopkins University, studied the effect of earthworms on forest chemistry by comparing carbon composition in forests that vary in earthworm activity. They found forests with greater numbers of invasive earthworms tend to have litter and soil organic matter...

A handful of soil is a lot like a banana, strawberry and apple smoothie: Blended all together, it is hard to tell what's in there, especially if you have never tasted the fruits before.But when you look at soil's organic carbon closely, it has an incredible variety of known compounds. And looking closely is exactly what Cornell researchers have done for the first time -- at a scale of 50 nanometers (1 nanometer equals the width of three silicon atoms). Until now, handfuls of soil humus (or...
