Were large soda lakes the cradle of life?

Along with nitrogen and carbon, phosphorus is an essential element for life on Earth. It is a central component of molecules such as DNA and RNA, which serve to transmit and store genetic information, and ATP (adenosine triphosphate), ...

When yesterday's agriculture feeds today's water pollution

A study led by researchers at Université de Montréal quantifies for the first time the maximum amount of nutrients—specifically, phosphorus—that can accumulate in a watershed before additional pollution is discharged ...

Climate change and its effects on Rocky Mountain alpine lakes

Alpine lakes in the Rocky Mountains are important biological hot spots of that ecosystem. These lakes do not have enough nutrients to support large amounts of aquatic life because of the cold climate in the surrounding watershed. ...

Calcium to phosphorus ratio in pig diets established by new study

The amount of digestible calcium included in pig diets has a direct impact on phosphorus digestibility, but the optimum ratio between the two minerals has not yet been found. In a recent study from the University of Illinois, ...

Measuring phosphorus loss from Midwest crop fields

Field runoff from farms in the Lake Erie basin is often rich in soluble plant nutrients, including phosphorus. When this nutrient-rich runoff reaches the lake, the phosphorus can support abundant algal blooms that contaminate ...

Biology trumps chemistry in open ocean

Single-cell phytoplankton in the ocean are responsible for roughly half of global oxygen production, despite vast tracts of the open ocean that are devoid of life-sustaining nutrients. While phytoplankton's ability to adjust ...
