Florida alligators travel upstream and downstream between marshes and the coast By Cheryl Dybas, NSF 'Gators. They're everywhere in freshwater areas of the Southeastern U.S. Now, scientists have found American alligators also swim into the brackish waters of estuaries, places where rivers meet the sea, out into the coastal zone and back again. These "commuter" alligators connect very different habitats, creating links between marine, estuarine and freshwater food webs. "Alligators need...

Researchers eavesdropping on complex signals emanating from a remote Wisconsin lake have detected what they say is an unmistakable warning "” a death knell "” of the impending collapse of the lake's aquatic ecosystem. The finding, reported today (April 29) in the journal Science by a team of researchers led by Stephen Carpenter, a limnologist at the University of Wisconsin-Madison, is the first experimental evidence that radical change in an ecosystem can be detected in advance,...

A new study co-authored by professor Kam Tang of the Virginia Institute of Marine Science reveals that tiny aquatic organisms known as "water fleas" play an important role in carrying hitchhiking bacteria to otherwise inaccessible lake and ocean habitats. The article, "Bacteria dispersal by hitchhiking on zooplankton," appeared in the June 29 issue of the Proceedings of the National Academy of Sciences. It was co-authored by scientists from the Leibniz-Institute of Freshwater Ecology and...

Seven-year experiment shows that pond communities bear a lasting imprint of random events in their past Scientist Jon Chase once worked in a lab that set up small pond ecosystems for experiments on species interactions and food webs. "We would try to duplicate pond communities with a given experimental treatment," he says. "We put 10 of this species in each pond, and five of these species, and eight of the other species, and 15 milliliters of this nutrient and 5 grams of that and 'sproing,'...

New study argues need for dual nutrient strategy to improve aquatic ecosystemsExcess phosphorus and nitrogen produced by human activities on neighboring land is making its way into our coastal waters and degrading both water quality and aquatic life. Although historically the priority has been to control phosphorus, Professor Hans Paerl, from the University of North Carolina in the US, argues that nitrogen imbalance is equally damaging. He adds that a dual nutrient strategy "“ tackling...

A study, by more than 100 experts looked at the world's water ecosystems, ranging from lakes, rivers, tropical waters and Arctic seas.The research was led by Professor Nicholas Polunin of Newcastle University, who said: "Across the 21 different ecosystems we have looked at, direct human actions have long been exceeding and will long continue to exceed the effects of climate change in almost every case."That is not to say that climate change isn't happening or is unimportant."Coral reefs...


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.
