Climate change allows invasive weed to outcompete local species
ScienceDaily (June 1, 2011) — Yellow starthistle already causes millions of dollars in damage to pastures in western states each year, and as climate changes, land managers can expect the problem with that weed and others to escalate.When exposed to increased carbon dioxide, precipitation, nitrogen and temperature — all expected results of climate change — … Continue reading
Aquarius to illuminate links between salt, climate
ScienceDaily (May 18, 2011) — When NASA’s salt-seeking Aquarius instrument ascends to the heavens this June, the moon above its launch site at California’s Vandenberg Air Force Base won’t be in the seventh house, and Jupiter’s latest alignment with Mars will be weeks in the past, in contrast to the lyrics of the song from … Continue reading
Stable temperatures boost biodiversity in tropical mountains, study finds
ScienceDaily (June 9, 2011) — We often think of rainforests and coral reefs as hotspots for biodiversity, but mountains are treasure troves for species too — especially in the tropics, scientists say. But what drives montane biodiversity? The diversity of plants and animals in tropical mountain ranges may have something to do with the stable … Continue reading
NASA’s NPP satellite successfully completes thermal vac testing
ScienceDaily (May 24, 2011) — The NASA National Polar-orbiting Operational Environmental Satellite System (NPOESS) Preparatory Project (NPP) climate and weather satellite has successfully passed all environmental testing with the recent completion of thermal vacuum testing at Ball Aerospace & Technologies Corp’s production and test facility in Boulder, Colo.The two months of testing verified that the … Continue reading
Venice to suffer fewer storm surges
ScienceDaily (June 10, 2011) — Venice — the City of Dreams — may have one less nightmare to deal with following a finding that the frequency of extreme storm surge events generated by Adriatic Sea tempests could fall by about 30 per cent by 2100.A team of international scientists led by CSIRO’s Dr Alberto Troccoli … Continue reading
Methane gas from cows: The proof is in the feces
ScienceDaily (June 7, 2011) — Scientists could have a revolutionary new way of measuring how much of the potent greenhouse gas methane is produced by cows and other ruminants, thanks to a surprising discovery in their poo.Researchers from the University of Bristol and the Teagasc Animal and Grassland Research Centre in Ireland, have found a … Continue reading
Genetic study clarifies evolutionary origin of elusive montane red fox
ScienceDaily (May 20, 2011) — North American red foxes originated from two separate genetic lineages that were isolated from each other by glaciers some half a million years ago, according to a U.S. Forest Service Pacific Northwest Research Station study.The research — featured in the April/May 2011 issue of Science Findings, a monthly publication of … Continue reading
Change is the order of the day in the Arctic
ScienceDaily (May 12, 2011) — Climate change in the Arctic is occurring at a faster and more drastic rate than previously assumed, according to experts attending the AMAP conference in Copenhagen. The latest scientific data show that developments in the Arctic’s climate are closely related to developments in the rest of the world.“The order of … Continue reading
Climate change analysis predicts increased fatalities from heat waves
ScienceDaily (May 4, 2011) — Global climate change is anticipated to bring more extreme weather phenomena such as heat waves that could impact human health in the coming decades. An analysis led by researchers at the Johns Hopkins Bloomberg School of Public Health calculated that the city of Chicago could experience between 166 and 2,217 … Continue reading
Can Siberian hot springs reveal ancient ecology?
ScienceDaily (Apr. 27, 2011) — Exotic bacteria that do not rely on oxygen may have played an important role in determining the composition of Earth’s early atmosphere, according to a theory that UChicago researcher Albert Colman is testing in the scalding hot springs of a volcanic crater in Siberia.He has found that bacteria at the … Continue reading
