A coupled-cycles framework is essential to balancing human needs with the health of the planet If society wants to address big picture environmental problems, like global climate change, acid rain, and coastal dead zones, we need to pay closer attention to the Earth's coupled biogeochemical cycles. So reports a special issue of Frontiers in Ecology and the Environment, published this month by the Ecological Society of America. "There are nearly seven billion people on the planet. And our...

Frontiers in Ecology and the Environment issue examines the basic elements of life In the search for life on Mars or any planet, there is much more than the presence of carbon and oxygen to consider. Using Earth's biogeochemical cycles as a reference point, elements like nitrogen, iron and sulfur are just as important for supporting life. As explored in studies published in February's open-access Special Issue of Frontiers in Ecology and the Environment, the most basic elements work together...

DNA evidence supports a coastal northeastern Atlantic glacial refugium for a boreal tree species Can a road-trip across eastern North America, ancient ice sheets, and DNA samples unlock the ancestral history of jack pine trees? Julie Godbout and colleagues from the Universit© Laval, Quebec, Canada, certainly hoped that driving across northeastern U.S. and Canada to collect samples from jack pine trees would shed some light on how glaciers may have impacted present-day pine genetics....

Study finds that the areas are most important for a limited range of land cover types Protected areas are generally seen as a triumph for the preservation of nature, yet the reality on the ground is more complex. The world's largest protected areas encompass vast amounts of wilderness but do not extensively overlap the highest priority areas for conservation or include unusually large numbers of birds, amphibians, or mammals, according to an analysis published in the November issue of...

From 1999 to 2009, an average of one new species of plant or animal was discovered every three days in the Amazon region, according to a report released Tuesday by environmental watchdog WWF. The report, which was entitled "Amazon Alive: A Decade of Discoveries 1999-2009" and compiled as part of the group's Living Amazon Initiative, "clearly shows the incredible diversity of life in the Amazon," Francisco Ruiz, the head of the project, said in a statement. As part of the Living Amazon...

There are more than one million different types of creatures living in the world's oceans today, according to a newly-released, decade-long effort to record marine life species around the world. The Census of Marine Life, which was an international effort began that in the year 2000 and was officially completed on Monday, featured more than 2,700 experts, from over 80 different countries and territories, representing 670 different institutions. "We prevailed over early doubts that a Census...

Scientists are gaining a deeper understanding of marine mammal travel patterns using a large-scale tracking network. A new PLoS collection, created in conjunction with the Pacific Ocean Shelf Tracking (POST) Program and the Census of Marine Life (CoML), will highlight the variety of ways scientists are using this large POST network to trace marine animal movement in the Northeast Pacific Ocean. The PLoS POST Collection launches on August 31st. POST provides a tool for researchers from...

New research from the University of Sheffield has discovered that the deep open ocean, by far the largest habitat for life on Earth, is currently the most under-explored area of the sea, and the one we know least about. The research, which was published August 1, 2010 in the journal PLoS ONE, has mapped the distribution of marine species records and found that most of our knowledge of marine biodiversity comes from the shallow waters or the ocean floor, rather than the deep pelagic ocean- the...

The waters surrounding Australia and Japan are home to the greatest variety of aquatic lifeforms, and crustaceans such as crabs, lobsters, crayfish and shrimp are the most common species in the world's seas, according to the findings of the Census of Marine Life. The information, which was disclosed in a series of articles published Monday in the open access journal PLoS ONE, comes from a decade-long effort by more than 360 scientists to catalog species in 25 different regions, ranging from...

New study suggests primary role of ocean temperature in the distribution of marine biodiversity, documents significant overlap between areas of high human impact and diversity hotspots In an unprecedented effort that will be published online on the 28th of July by the international journal Nature, a team of scientists mapped and analyzed global biodiversity patterns for over 11,000 marine species ranging from tiny zooplankton to sharks and whales. The researchers found striking similarities...

Hispaniolan pine (Pinus occidentalis) is found largely on the Caribbean island Hispaniola growing on the slopes. Hispaniolan pine forests can be found on the island of Haiti and the Dominican Republic in the mountain range. The Hispaniolan pine can grow in mixed stands of trees with other broadleaf trees at elevations between 2789 and 6890 feet and in pure stands from 6890 feet up to 10,420 feet. These trees are also found in the lowlands growing in acidic soil that is rich in iron and...
