A new study led by researchers from the University of York suggests protected areas in East Africa are not conserving plants such as the iconic Acacia tree. Acacia, the thorny flat-topped tree that characterizes the African savannas, is an important component of ecosystem diversity. However, the researchers found that the majority of Acacia biodiversity 'hotspots' receive little protection through the protected area network, which includes national parks, nature and forest reserves. The...

Ecological Tipping Points Examined In Hopes Of Preventing Them

University of California - Santa Barbara Predation by otters keeps urchin populations in check, allowing kelp —— a favorite food of urchins —— to flourish. But what if otters were harvested to near extinction for their fur? The resulting overabundance of urchins would decimate the kelp forest, leaving little food or shelter for fish and invertebrates. And so it may go, as declines in these species are likely to affect others. Such is the potential trickle-down...

Health Of Marine Ecosystems Associated With Health Of Manatees
2012-10-03 12:40:10

April Flowers for redOrbit.com - Your Universe Online A team of scientists, led by George Mason University, have conducted a long-term study of manatees which may be a benchmark in determining health threats to marine mammals. The study, which ran over ten years in Belize, examined the behavioral ecology, life history and health of manatees in an area relatively undisturbed by humans. “Manatees are the proverbial ℠canaries in the mineshaft,´ as they serve as indicators...

Climate Change Could Cause Whole Marine Ecosystems To Move
2012-09-24 15:04:12

Michael Harper for redOrbit.com — Your Universe Online The effects of climate change have been well documented, driving some creatures and organisms from their homes and even changing landscapes which have been familiar for centuries. Now, some scientists have found yet another impending change in another familiar ecosystem, suggesting that some Pacific ecosystems could move as far as 600 miles away from their current state. What´s more, these changes could take place in less...

Brett Smith for redOrbit.com — Your Universe Online Human activities and disturbances can put a significant amount of stress on local environments and a new research review has shown that the functional diversity in arid, desert environments can be affected by the hand of man. According the report published in the Journal of Arid Environments, mammalian communities living in dry ecosystems are "drastically changing" as a result of human activities. "We report for the first...

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...

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...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
