Dead starfish confuse biologists

A beach ranger's discovery of hundreds of dead starfish along Heceta Beach has confused shellfish biologists who can't determine why the starfish died in such numbers in just one place.

... the starfish may have been killed by disease or low oxygen levels in the water.

Endocrine Disruptors and Intersex Fish Identified in Minnesota Lakes

Endocrine disrupting chemicals were identified in all of the 11 Minnesota lakes studied by the U.S. Geological Survey, St. Cloud State University and the Minnesota Pollution Control Agency.

Female characteristics were observed in male fish in most of the lakes studied.

Although endocrine disrupting chemicals and endocrine disruption in both resident fish and caged minnows were generally more pronounced in lakes surrounded by urban and agricultural lands, they were also identified in more remote lakes. Further studies are needed to determine if there is a link between the prevalence of these chemicals and surrounding land use.
