Scientists can predict how the distance marine larvae travel varies with ocean temperature - a key component in conservation and management of fish, shellfish and other marine species - according to a new study from the University of North Carolina at Chapel Hill.

In a dissertation at the Department of Applied Environmental Science (ITM), Stockholm University, Maria Pettersson has examined whether purified wastewater from municipal purification plants and cellulose factories in Sweden contains hormone-disrupting compounds in such amounts that they are affecting fish. She has also studied how the levels of these compounds can be reduced in wastewater.
