Research: Snails were overlooked contributors to marsh destruction

...nails likely killed off thousands of acres of salt marsh in the Southeast in recent years. Periwinkle snai...hich lasted from 1999 to 2001, weakened and killed marsh grasses such as cordgrass, or Spartina alterniflora, so extensively that the snails moved from finis...

GROWing the next generation of water recycling plants

... other plant species include the yellow flag iris, marsh marigold, and the common reed. They are chosen to be resistant to the pollutants they absorb. By planting more than one species, the engineers guard against an unusually dirty batch of water exceeding a particular species' tolerance level. Should one...

Iraq's marshes show progress toward recovery

...ed are functioning at levels close to those in one marsh that remained undrained. The fast recovery of plant production, overall good water quality, and rapid restoration of most wetland functions seem to indicate that the recovery of ecosystem function is well under way. Richardson and Hussain are not co...

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. Whil...

Even a little cooling helps after cardiac arrest

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. Whil...

Invasive species alter habitat to their benefit

...ve cattails. She also noted that the areas of each marsh with lots of hybrid cattails had higher nutrient levels and heavier mats of dead cattail stems than areas with only native wetland plants. The plants growing in these invaded areas also were different, with fewer classic wetland species, such as bulr...

Species unique to tidal marshes face threats

...most common in North America and China. Some tidal marsh species are protected from high salinity by relati...ls often found in tidal marshes. Why endemic tidal marsh species seem to be largely restricted to North America--which has 24 of the worldwide total of 25--i...

Microbes compete with animals for food by making it stink

...hey are not passively waiting on the bottom of the marsh floor for the rest of the community to deliver feces and other wastes that are not useful to anybody else," he added. "They are also trying to grab what they can at the start." Hay hopes the research will make ecologists think more critically about...
