In the land of 10,000 lakes, one lake has been the starting place for research with implications for big lakes around the world. According to a study published online this week in Science, University of Minnesota researchers, building from studies of nitrogen levels in Lake Superior, uncovered a good news/bad news scenario for lake health that has long-term, global implications for pollution control efforts. While many water-quality cleanup efforts focusing on the reduction of phosphorus...

A team of Spanish researchers have used different geological samples, extracted from the Enol lake in Asturias, to show that the Holocene, a period that started 11,600 years ago, did not have a climate as stable as was believed. The Holocene period, which includes the last 11,600 years of our history, has always been described as a stable period in terms of climatic conditions, especially when compared to the abrupt changes that occurred in the last ice age, which ended around 10,000 years...

Michigan State University scientists have developed a pioneering, comprehensive approach that makes conserving and managing freshwater lakes, streams and wetlands more integrated and effective. "We call our approach landscape limnology," said Patricia Soranno, MSU associate professor of fisheries and wildlife. "It's a new way to study freshwater that considers all freshwaters together "“ lakes, rivers and wetlands "“ as they interact with one another and with natural and human...

U of Minnesota study involved a 10-year outdoor experiment Rising levels of carbon dioxide may overheat the planet and cause other environmental problems, but fears that rising CO2 levels could directly reduce plant biodiversity can be allayed, according to a new study by a University of Minnesota scientist Peter Reich. In fact, rising CO2 may actually help counteract losses of diversity from another environmental villain: the global rain of nitrogen from fertilizers and exhaust fumes. The...

Hypoxia, or lack of oxygen, in bottom waters is a well known environmental problem. New research at the University of Gothenburg, Sweden adds to the list of ill effects: hypoxia leads to increased levels of manganese, which damages the immune response in marine animals.Water eutrophication and the resulting hypoxia is an ever-current issue, not least in connection with summer algal blooms. A more recently acknowledged problem is that hypoxia, which occurs when algae is broken down, increases...

By Rodbell, Donald T ABSTRACT The demonstration described in this paper attempts to illustrate the main controls on the vertical circulation of lake water. This phenomenon integrates the effects of annual air temperature cycles, fetch, and possible groundwater sources to a lake. Because the nature of a lake's circulation pattern has an effect on the "quality" of the sediment record preserved, it is among the most important limnological processes for students to understand. This...

By Chicago Tribune Jul. 2--The Chicago Park District issued a swim ban Wednesday afternoon in response to a National Weather Service seiche warning, officials said. The warning was issued after a massive storm front currently over the lower peninsula of Michigan crossed Lake Michigan in the early afternoon Wednesday and piled the water toward the Michigan shore as it traveled east. Water flooded the harbor in St. Joseph, Mich., and crept more than 15 feet across the sand there, said...

NEAH BAY, Wash. -- The mass starvation deaths of murres on Tatoosh Island off the Olympic Peninsula may be due in part to unusual weather patterns along the West Coast, scientists say. Last year didn't have the winds and currents necessary to maintain the network of marine food crucial to the seabirds' diet. Breeding failures during the summer were preceded by tens of thousands of birds washing up dead on beaches in Washington, Oregon and California. In Washington, the state's largest...

The Black Guillemot or Tystie (Cepphus grille) is a medium-sized auk measuring 32-38 cm in length, and with a 49-58 cm wingspan. Adult birds have black bodies with a white wing patch, a thin dark bill and red legs and feet. They show white wing linings in flight. In winter, the upperparts are pale grey and the underparts are white. The wings remain black with the large white patch on the inner wing. Their preferred breeding habitat is rocky shores, cliffs and islands on northern...
