Fundamentals of Biology 2015-01-01T00:00:00Z Livestock production places hefty demands on the environment in the form of land use, nitrogen cycle disruption and greenhouse gas emissions. Surprising Changes Will Affect Biodiversity in 2019 2018-12-27T05:00:00Z “It wasn’t entering into the paradigm of how we think the nitrogen cycle works,” Houlton says. Mystery of the Earth's Missing Nitrogen Solved 2018-05-29T04:00:00Z While Curiosity has been busy finding signs of an ancient nitrogen cycle on the Red Planet, Opportunity — which touched down in January 2004 — has just completed the first ever extraterrestrial marathon. NASA's Opportunity rover just completed an 11-year marathon on Mars 2015-03-25T04:00:00Z But the researchers say that it's enough to warrant continued research into evidence for an ancient nitrogen cycle on Mars. Curiosity rover finds new signs that Mars could have supported life 2015-03-24T04:00:00Z This illustration shows the role of bacteria in the nitrogen cycle. Fundamentals of Biology 2015-01-01T00:00:00Z Apart from climatic change, other manifestations of human impact in the Anthropocene, from interference in the nitrogen cycle to plastics in the oceans, only add to the grim outlook. A Darker View of the Age of Us - the Anthropocene 2014-06-18T04:00:00Z The variable ratios between denitrification and anammox previously observed in the ocean are thus attributable to localized variations in OM quality and quantity and do not necessitate a revision to the global nitrogen cycle. [Report] Organic Matter Stoichiometry, Flux, and Oxygen Control Nitrogen Loss in the Ocean 2014-04-29T14:56:40.339Z Corn is the staple, but beans and squash are also necessary to complete the nutrition and nitrogen cycle. Rewriting the Menu in Tulum, Mexico 2014-03-10T21:57:08Z This component of the nitrogen cycle constitutes an additional loss term for fixed nitrogen in soils and a source for reactive nitrogen in the atmosphere. [Report] HONO Emissions from Soil Bacteria as a Major Source of Atmospheric Reactive Nitrogen 2013-09-12T17:57:06.197Z Whales that are beached on unpopulated shores are left to break down into the nitrogen cycle “as nature has done for millennia.” How Harmful for Whales Is Shipping? [Excerpt] 2013-08-09T14:15:01.067Z The causes are man made and have come to dominate Nature's global nitrogen cycle. Leaving our mark: Fossils of the future 2012-11-03T00:34:29Z We still need a better understanding of how our planet functions and of atmospheric cycles, such as the nitrogen cycle. Socially responsible science 2012-10-10T21:51:33.387Z Kudos on studying the marine nitrogen cycle, but please use more meaningful numbers to illustrate your point. Scientist at Work: Q. and A. on the Nitrogen Cycle 2011-05-26T15:57:10Z They warned that two of these - climate and the nitrogen cycle - are in danger of failing, while a third - biodiversity - is already in meltdown. Human age 2011-05-10T23:07:44Z In the meantime, I would point anyone hungry for more information on the global nitrogen cycle to this figure from the journal Nature.
