Invasive species alter habitat to their benefit
When scientists study habitats that alien species have invaded, they usually find predictable patterns. The diversity of native species declines, and changes occur in natural processes such as nutrient cycling, wildfire frequency and the movement of water through the system.   view more (2006-08-10)

Restoring seagrass beds: Is it for the birds?
Although most people consider bird droppings a nuisance, scientists at the Dauphin Island Sea Lab see them as a rich source of phosphorus, a natural fertilizer for grassbeds which have been destroyed by boat propellers.   view more (2006-04-11)

How healthy is that marsh? Biologists count parasites
Is that salt marsh healthy? To answer this, Sea Grant biologists are cracking open common marsh snails and counting parasitic worms. Their claim: the more parasites, the healthier the marsh.   view more (2006-05-19)

Planning for stewardship an important part of successful ecological restoration
Restoring degraded ecosystems around Seattle — and giving them a fighting chance to stay healthy — can be as much about PR as the right plants. That's what students learn through the University of Washington's Restoration Ecology Network, a program of teaching and research recognized nationally in this week's issue of Science magazine.   view more (2006-06-30)

Discovery points to more effective ways of regulating cell signalling
A discovery made at The Walter and Eliza Hall Institute provides new insights into enhancing the function of the protein SOCS3, which regulates the response of cells to external stimuli.   view more (2006-04-21)

Food for Flight: Monarch Butterfly Migration and Forest Restoration
USDA Forest Service (FS) research in the Ouachita Mountains of Arkansas suggests that decades of fire suppression have reduced the area's food supply for migrating monarch butterflies-and that restoration efforts that include prescribed burning can reverse this trend.   view more (2006-11-20)
