River mystery solved: Scientists discover how 'Didymo' algae bloom in pristine waters with few nutrients

ScienceDaily (June 3, 2011) — The pristine state of unpolluted waterways may be their downfall, according to research results published 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 so with a little help from its friends--in this case, bacteria--which allow it to make use of nutrients like phosphorus.

Blooms of Didymo, also known as "rock snot," says scientist P.V. Sundareshwar of the South Dakota School of Mines and Technology, are made up of stalks that form thick mats on the beds of oligotrophic, or low-nutrient, streams and rivers. Sundareshwar is the paper's lead author.

"In recent decades, human activities have led to many uncommon environmental phenomena," he says. "Now we have Didymo."

The freshwater diatom has become notorious. Didymo has taken over low-nutrient rivers in North America and Europe. It has also invaded water bodies in the Southern Hemisphere, including those in New Zealand and Chile.

Because its blooms alter food webs and have the potential to impact fisheries, "Didymo presents a threat to the ecosystem and economic health of these watercourses," says Sundareshwar.

Algae blooms are usually linked with the input of nutrients that fuel the growth of microscopic aquatic plants. Didymo's ability to grow prolifically in waters where nutrients such as phosphorus are in short supply puzzled scientists.

Environmental managers tried to mitigate Didymo blooms and predict their spread. But how the diatoms sustained such high growth in oligotrophic systems was unknown.

In a study funded by the National Science Foundation (NSF) and the State of South Dakota Carbon Scientist fund, Sundareshwar and colleagues revealed that Didymo is able to concentrate phosphorus from the water.

The scientists conducted their research in Rapid Creek, an unpolluted mountain stream in western South Dakota where Didymo was first observed in 2002. The creek regularly has Didymo blooms, with 30 to 100 percent of the streambed covered with Didymo over an area up to ten kilometers (6 miles) long.

Didymo thrives in Rapid Creek through biogeochemical processes in biofilms in the mats. As Didymo mats form, new stalks develop at the surface and older stalks--which have already bound phosphorus--are displaced to the mats' inner regions.

Phosphorus is available to Didymo thanks to the activity of the bacteria that live inside these mats.

"This study solves the puzzle of how Didymo can produce such large blooms in low-nutrient rivers and streams," says Tim Kratz, program director in NSF's Division of Environmental Biology.

"It has uncovered the fascinating mechanism by which Didymo 'scrubs' phosphorus from a stream or river," says Kratz, "then creates a microenvironment that allows microbes to make this nutrient available for Didymo's growth."

The concentration of phosphorus on Didymo mats far exceeds the level expected based on the nutrient content of surface waters, says Sundareshwar.

"The ability of the mats to store phosphorus is tied to the availability of iron in the water."

Didymo cells adsorb, or condense on their surfaces, both iron and phosphorus. Then bacterial processes in the mat interact with iron to increase the biological availability of phosphorus.

The process results in abundant phosphorus for cell division, "and hence," says Sundareshwar, "a resolution to the paradox of Didymo blooms in oliogotrophic streams and rivers."

The result will help scientists and managers identify water bodies susceptible to Didymo blooms.

"It also has the potential to lead to discoveries that may stem this organism's prolific growth in rivers around the world," says Sundareshwar.

"This is how science is supposed to work--research conducted at one small creek in South Dakota can be translated to places across the globe."

Co-authors of the paper are S. Upadhayay, M. Abessa, S. Honomichl, C. Sandvik, and A. Trennepohl of the South Dakota School of Mines and Technology; B. Berdanier of South Dakota State University and A. Spaulding of the U.S. Geological Survey in Boulder, Colo.

http://asf.ca/news.php?id=666&type=press Top Conservation Award for Monsieur Saumon April 28th, 2011 For immediate release  Editor's Note: A full-sized image for printing is available at 300 dpi. Click here St. Andrews, NB ….. The Atlantic Salmon Federation (ASF) presented its top Canadian conservation award to Yvon  Côté, known as Monsieur Salmon in Québec, in Montréal on Wednesday, April 27. Presented in conjunction with ASF’s board meeting, Directors from both Canada and the United States were present to honour their colleague’s commitment to conservation of salmon and their habitat. "Yvon Côté has guided the Fédération québécoise pour le saumon Atlantique (FQSA), ASF's Regional Council in Québec,  through challenging times with poise and a level headedness that has brought praise from all sectors of the Atlantic salmon world," states ASF (Canada) Chairman, the Honourable Michael Meighen.  "Yvon goes beyond the call of duty to help solve problems in a spirit of respect and cooperation, while trying to include all stakeholders." In Québec, he led the way for the creation of a federally funded "Salmon Economic Development Program", which provides funds to facilitate development and conservation initiatives in the province’s rivers. Yvon’s knowledge of Atlantic salmon issues and biology is uncontested.  For more than 20 years, he held various positions within the Québec Ministry of Natural Resources and Wildlife.  During his tenure, he completed many field research projects and was the chief Atlantic salmon biologist until he retired from the public service in 1996. He has served as President of the FQSA since 2000.  Founded in 1984, FQSA is a non-profit organization that works to preserve and improve salmon rivers, develop Québec’s salmon sport fishery, and protect the resource and its habitat against threats.  FQSA has 35 affiliated river management groups and more than a thousand members. The award, first presented in 1975, is named in memory of T.B. "Happy" Fraser of Montréal for the many contributions he made during his lifetime to protect and conserve wild Atlantic salmon.  Since then ASF has honoured more than 40 people, who, like Mr. Côté, have contributed significantly to ensure the future survival of this iconic species. The Atlantic Salmon Federation is dedicated to the conservation, protection and restoration of wild Atlantic salmon and the ecosystems on which their well being and survival depend. ASF has a network of seven regional councils (New Brunswick, Nova Scotia, Newfoundland and Labrador, Prince Edward Island, Quebec, Maine and Western New England).  The regional councils cover the freshwater range of the Atlantic salmon in Canada and the United States. -30- Cutline: Yvon Côté (centre) was presented with the Atlantic Salmon Federation's T.

Prix de conservation le plus prestigieux décerné à Monsieur Saumon Press Releases   http://asf.ca/news.php?id=666&type=press Prix de conservation le plus prestigieux décerné à Monsieur Saumon April 28th, 2011   Photo St. Andrews (Nouveau-Brunswick) ... Le mercredi 27 avril à Montréal, la Fédération du saumon atlantique (FSA) a présenté son prix de conservation le plus prestigieux à Yvon Côté, baptisé Monsieur Saumon, au Québec. Le prix a été décerné à la réunion du conseil de la FSA par les présidents des conseils canadien et américain afin d’honorer l’engagement de leur collègue envers la conservation du saumon atlantique sauvage et de son habitat. « Yvon Côté a dirigé la Fédération québécoise pour le saumon Atlantique (FQSA), conseil régional de la FSA au Québec, avec assurance et lucidité alors qu’elle traversait une période difficile, ce qui lui a valu des louanges de tous les secteurs du monde du saumon atlantique, de dire l’honorable Michael Meighen, président de la FSA (Canada). Yvon va bien au-delà de ce qu’impose le devoir pour résoudre les problèmes dans le respect et la coopération, tout en sollicitant la participation de toutes les parties prenantes. » Au Québec, il a ouvert la voie à la création d’un « Plan de développement économique du saumon atlantique » financé par le gouvernement fédéral qui accorde des fonds pour favoriser la conception et la réalisation de projets de conservation dans les rivières de la province. Sa connaissance des enjeux et de la biologie du saumon n'est plus à démontrer. Au cours des 20 dernières années, Yvon a occupé divers postes au ministère des Ressources naturelles et de la Faune du Québec. Pendant ce temps, il a réalisé de nombreux projets de recherche et a été le biologiste en chef du saumon jusqu'à son départ à la retraite de la fonction publique en 1996. Il est président de la FQSA depuis l'an 2000. Créée en 1984, la FQSA est un organisme sans but lucratif qui se voue à la préservation et à la mise en valeur des rivières à saumon, au développement de la pêche sportive au saumon et à la défense de la ressource saumon et de son habitat contre toutes les menaces. La FQSA compte 35 clubs affiliés de gestion de rivières et plus de mille membres. Le prix, présenté pour la première fois en 1975, est nommé à la mémoire de T.B. « Happy » Fraser de Montréal pour les nombreuses contributions faites au cours de sa vie pour protéger et conserver le saumon atlantique sauvage. Depuis lors, la FSA a honoré plus de 40 personnes comme M. Côté, qui ont fait une contribution notable pour assurer la survie de cette espèce emblématique. La Fédération du saumon atlantique est vouée à la conservation, à la protection et au rétablissement du saumon atlantique sauvage et des écosystèmes dont il dépend pour son bien-être et sa survie. Elle regroupe sept conseils régionaux (Nouveau-Brunswick, Nouvelle-Écosse, Terre-Neuve et Labrador, Île-du-Prince-Édouard, Québec, Maine et ouest de la Nouvelle-Angleterre) qui couvrent toute l'aire de distribution du saumon atlantique en au douce au Canada et aux États-Unis. -30- Photo Yvon Côté (au centre) s'est vu remettre le Prix  de conservation de la FSA T.B. « Happy » Fraser par Bill Taylor, président de la FSA, et le sénateur Michael Meighen, président du conseil (Canada) de la FSA le 27 avril dernier à Montréal.
