Ocean Food Chain Likely Disrupted By Climate Change
2013-07-03 08:08:44

April Flowers for redOrbit.com - Your Universe Online A new study from the University of Southern California (USC) reveals climate change may be weeding out the bacteria that form the base of the ocean's food chain by selecting certain strains for survival. There are winners and losers in everything, including climate change. Knowing which organisms will thrive and which will perish as atmospheric carbon dioxide levels and temperatures rise globally is increasingly important to...

The overuse of nitrogen fertilizers in agriculture can wreak havoc on waterways, health and the environment. An international team of scientists aims to lessen the reliance on these fertilizers by helping beans and similar plants boost their nitrogen production, even in areas with traditionally poor soil quality. Researchers from the Center of Plant Genomics and Biotechnology at the Technical University of Madrid (UPM) and the Advanced Photon Source (APS) at the U.S. Department of...

Marine Microbes Engage In Unusual Symbiosis
2012-09-22 09:56:42

April Flowers for redOrbit.com - Your Universe Online A study published in this week's issue of Science shows how tiny, single-celled algae and a highly specialized bacteria have formed a partnership that helps keep the ocean fertilized.  This symbiotic pair takes nitrogen from the atmosphere and "fixes" it into a form that other organisms can use. The results of the study emerged from the investigation of a mysterious nitrogen-fixing microbe that has a very small genome. ...

Research study in “Nature” confirms improved method by marine scientists from Kiel In order to predict how the Earth´s climate develops scientists have to know which gases and trace elements are naturally bound and released by the ocean and in which quantities. For nitrogen, an essential element for the production of biomass, there are many unanswered questions. Scientists from Kiel, Bremen and Halifax have now published a research study in the international journal...

Biologists at Bielefeld University have developed a new method for quantifying the effect of non-native species on ecosystem functioning They can estimate whether native plants in the neighbourhood of invasive species incorporate the nitrogen fixed by the latter. The biologists examined the Sydney Golden Wattle (Acacia longifolia), an Australian shrub that has established itself in Mediterranean climates worldwide. They found that the invasive species threatens native ecosystems not only...

A 125-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled A 125-year debate on how nitrogen-fixing bacteria are able to breach the cell walls of legumes has been settled. A paper to be published on Monday by John Innes Centre scientists reports that plants themselves allow bacteria in. Once inside the right cells, these bacteria take nitrogen from the air and supply it to legumes in a form they can use, ammonia. Whether the bacteria...

The genome of Medicago, a close relative of alfalfa and a long-established model for the study of legume biology, has been sequenced by an international team of scientists, capturing around 94 per cent of its genes. The research gives new insights into the evolution of the Papilionoid subfamily of legumes, which includes peas, soybean and all legumes grown as crops. Plants in this family can house and work with bacteria to provide them with nitrogen from the air. The new findings...


Word of the Day
omphalos
  • The navel or umbilicus.
  • In Greek archaeology: A central boss, as on a shield, a bowl, etc.
  • A sacred stone in the temple of Apollo at Delphi, believed by the Greeks to mark the 'navel' or exact center-point of the earth.
