Reducing the size of the Lake Erie "dead zone" to acceptable levels will require cutting nutrient pollution nearly in half in coming decades, at a time when climate change is expected to make such reductions more difficult. That's one of the main conclusions of a comprehensive new study that documents recent trends in Lake Erie's health. It offers science-based guidance to policymakers seeking to reduce the size of toxic algae blooms and oxygen-starved regions called hypoxic zones, or dead...

Toxic Algae Most Likely Cause Of Ancient Chilean Whale Strandings
2014-02-26 10:08:48

Brett Smith for redOrbit.com - Your Universe Online A site in the Atacama Desert of Northern Chile has become well known for its wealth of ancient marine mammal fossils, deposited there by a series of mass strandings. While the cause of whale or other mammal strandings that take place today can often be identified, the cause behind ancient strandings is much more difficult to pin down. According to a newly published report in the Proceedings of the Royal Society B, an international...

Massive Manatee Deaths In 2013 Attributed To Red Tide Algae
2013-10-31 15:40:37

Michael Harper for redOrbit.com - Your Universe Online According to the Florida Fish and Wildlife Research Institute in St. Petersburg, the number of manatee deaths in 2013 has already reached a record high of 769 fatalities and there are still two months left to go in the year. These deaths account for about 15 percent of the total population and specialists expect the number to go even higher before the year is out. Motor boats, long the greatest mortal enemy of manatees, aren’t to...

Rise In Toxic Algal Blooms Climate Change
2013-10-25 10:07:28

Brett Smith for redOrbit.com - Your Universe Online Algae is probably best known for the green scum it forms on top of stagnant water, and in addition to looking unpleasant, some algal blooms host strains of cyanobacteria that are highly toxic. According to a new study in the journal Science, nutrient enrichment and rising global temperatures are increasing the toxicity of some algal blooms in freshwater lakes, ponds and estuaries around the world. As these 'eutrophic' processes...

Danish and Australian biologists have developed a technique to determine if seagrass contain sulfur. If the seagrass contains sulfur, it is an indication that the seabed is stressed and that the water environment is threatened. The technique will help biologists all over the world in their effort to save the world’s seagrass meadows. Seagrass meadows, such as eelgrass or Halophila, grow along most of the world's coasts where they provide important habitats for a wide variety of life...

A new report looks at how extreme weather and an increase in non-point source pollution from agriculture and failing septic systems are spurring the spread of harmful algal blooms. It includes a first-of-its-kind national online map showing that 21 states issued health advisories related to toxic algae at 147 lakes and rivers this summer. Ann Arbor, Michigan (PRWEB) September 26, 2013 Summer should be a time for fishing, boating and swimming with family on our nation’s lakes. Yet...

Legacy Of Acid Rain Threatens Eastern US Water Supplies
2013-08-27 06:39:58

Cary Institute of Ecosystem Studies Human activities are changing the water chemistry of many streams and rivers in the Eastern U.S., with consequences for water supplies and aquatic life, so reports a new study in the journal Environmental Science and Technology. In the first survey of its kind, researchers looked at long-term alkalinity trends in 97 streams and rivers from Florida to New Hampshire. Sites ranged from small headwater streams to some of the nation's largest rivers. Over...

Homes Of Giant Bacteria Invaded By Strangers

University of Southern Denmark Life is not a walk in the park for the world's largest bacteria, that live as soft, noodle-like, white strings on the bottom of the ocean depths. Without being able to fend for themselves, they get invaded by parasitic microorganisms that steal the nutrition, that they have painstakingly retrieved. This newly discovered bizarre deep ocean relationship may ultimately impact ocean productivity, report researchers from University of Southern Denmark now in the...
