City phosphorus, country phosphorus: can we mitigate P in different environments?

Phosphorus is essential for life, but there is such thing as too much of a good thing. In excess, phosphorus can cause algal blooms, creating dead zones in bodies of water. How do we prevent phosphorus from entering water systems? Katrina Macintosh and her team did a comprehensive review to track phosphorus from diffuse sources to find out.

Going, going, gone! Living shorelines send nitrogen packin’!

Coastal wetlands provide critical ecological services, but are rapidly disappearing from the planet. Salt marshes are a type of coastal wetland that provides habitat, food, and shelter, while preventing erosion, and protecting our water quality. Researchers are investigating how well reduce nutrient pollution, specifically nitrogen, from terrestrial and aquatic environments. A recent study discovered that living shorelines such as salt marshes are quite effective at removing nitrogen, especially in the first seven years after construction. These findings indicate that living shorelines are an effective solution to coastal pollution challenges.
