Diversity Helps To Maintain Grasslands During Drought
2012-08-09 10:21:11

Brett Smith for redOrbit.com - Your Universe Online As drought ravages grasslands across the United States, a few American scientists are looking into how different species of grass endure these harsh conditions. In a study that could impact everything from the beef industry to lawn care, a University of Kansas-led team examined the resilience of 426 species of grass from around the world and found that diversity is key in maintaining robust grasslands, according to their report...

Ecology and Phylogenetics-New Views of Earth's Biodiversity
2012-08-06 13:38:37

Scientists report new look at 'patterns in nature' in special issue of journal Ecology View patterns of nature in this photo gallery. Patterns in nature are in everything from ocean currents to a flower's petal. Scientists are taking a new look at Earth patterns, studying the biodiversity of yard plants in the U.S. and that of desert mammals in Israel, studying where flowers and bees live on the Tibetan plateau and how willow trees in America's Midwest make use of water. They're...

Protecting The Heart Of Borneo
2012-06-26 04:04:29

In Southeast Asia, the island of Borneo is home to one of the world´s most diverse rainforests, but its natural resources are under threat. Information from satellites is being used to evaluate the impact of the island´s future development. The mountainous island is the third largest in the world. It is an area of exceptional biological diversity and its natural resources have tremendous social and economic value at local, national and global levels. While still of great...

Symposium takes on the ecological science underpinning dollar assessments of ecosystem services at the 97th annual meeting of the Ecological Society of America in Portland, Oregon How much is a stream worth? Can we put a dollar value on a wetland? Some conservation proponents have moved to establish the economic value of "ecosystem services," the benefits that nature provides to people. The approach translates the beauty and utility of a wetland into pounds of phosphorus removed from...

University of Southampton researchers are pioneering a new way of measuring and monitoring the impact of industrial and agricultural development on the environment. Working in collaboration with East China Normal University, the Nanjing Institute of Geography and Limnology and the University of Dundee, the team has created the world's first long-term record of ecosystem health, which examines the past condition of environmental resources in China's Yangtze basin region, and helps develop...

'Green' market initiatives are increasing poverty; local ecosystem stewardship must be nurtured instead 'Green grabbing' - the rapidly-growing appropriation of land and resources in the name of 'green ' biofuels, carbon offsetting schemes, conservation efforts and eco-tourism initiatives — is forcing people from their homelands and increasing poverty, new research has found. Ecosystems being 'asset-stripped' for profit is likely to cause dispossession and further poverty amongst...

The Four Horsemen Of The Apocalypse Are Saddling Up
2012-06-07 12:17:11

Michael Crumbliss Twenty years ago scientists met at the Earth Summit in Rio to examine the climate and ecology of the Earth and man´s impacts. Two decades later 17 prominent ecologists have released a paper summarizing the evidence of the 1000´s of ecological studies undertaken in since 1992. In short they decided that the evidence is overwhelming and consistent. The danger of a catastrophic ecological crash is looming and is far more immediate than previously believed. In...

Street Lights Affect Delicate Ecosystems
2012-05-24 04:26:42

Brett Smith for RedOrbit.com Civilization has long been derided for intruding upon the habitats of wild animals, and even man´s smaller neighbors have been affected by the wheels of progress. Another measure of this impact can be seen in how street lighting is having a transformative effect on communities of insects and other invertebrates living near them, according to researchers at the University of Exeter in the United Kingdom. A report published in Biology Letters showed...

Drought-sensitive Southern Hemisphere Regions May Experience Even Less Rainfall
2012-05-21 03:22:30

Increasing aridity could lead to major problems for societies and ecosystems in already-arid places Warming climate may mean less rainfall for drought-sensitive regions of the Southern Hemisphere, according to results just published by an international research team. Geoscientist Curt Stager of Paul Smith's College in Paul Smiths, N.Y., and colleagues found that rainfall in South Africa during the last 1,400 years was affected by temperature--with more rain falling during cool periods...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
