[ Watch The Video: ‘Rock Snot’ Blooms Due To Native Algae ] Dartmouth College Recent growths not caused by human introductions or emergence of new genetic strain The recent blooms of the freshwater algae known as "rock snot" on river bottoms worldwide are caused by a native species responding to changing environmental conditions rather than by accidental introductions by fishermen or the emergence of a new genetic strain as widely believed, a Dartmouth College-led study...

Scientists discover how "Didymo" algae bloom in pristine waters with few nutrients The pristine state of unpolluted waterways may be their downfall, according to research results published in a paper this week in the journal Geophysical Research Letters. A species of freshwater algae that lives in streams and rivers, called Didymo for Didymosphenia geminata, is able to colonize and dominate the bottoms of some of the world's cleanest waterways--precisely because they are so clear. Didymo does...

BILL ENGLISH's comment on Wednesday (July 23) on the need for Environment Southland to better report all of the monitoring we do on the rivers of Southland says more about Bill's level of contact with Southland than the way we provide information to the region. We take our reporting far more seriously than any government department. It has taken 15 years for the Environment Ministry to come up with a "State of the Environment" report for the nation when we have been producing them for...

By Ed Dentry It's getting creepier by the minute out there. To the nightmare cauldron of invasive species that have made inroads into the state's waters, we now add quagga mussels. The Colorado Division of Wildlife said Tuesday that biologists have found quagga mussel larvae in Lake Granby. DNA tests performed by the DOW and the Bureau of Reclamation confirmed the invasive mussel's presence. Quagga mussels are slightly larger cousins of zebra mussels, which have spurred a rash of boat...

ELIZABETHTOWN -- Didymo, an invasive species also known as 'rock snot,' has been found in the Mad River, a waterway that runs through the heart of Vermont. A freshwater diatom, or microscopic alga, didymo erupts in noxious "blooms" covering rocky river beds with brown, clumpy growths that feel like wet wool, according to the Vermont Agency of Natural Resources. It is described as looking similar to a sewage spill with wet toilet paper streaming in the waterway. According to a press...
