JoAnn Burkholder
American limnologist
JoAnn Marie Burkholder (born 1953) is an American professor of aquatic ecology at the North Carolina State University, Raleigh. She was responsible for identifying the cause, a dinoflagellate Pfiesteria piscicida and its toxins, of mass deaths of fish that posed a public health hazard. Her studies also helped in improving legislation to control pollution and eutrophication.
Early life
[edit]Burkholder was born in 1953 in Rockford, Illinois.
Education
[edit]Burkholder received a bachelor's degree from Iowa State University in 1975 followed by an MS from University of Rhode Island (1981) and a Ph.D. from Michigan State University in 1986.
Career
[edit]Burkholder investigated fish deaths in a laboratory and found that the cause of that and deaths in North Carolina rivers were due to a dinoflagellate Pfiesteria piscicida which was normally found in the bottom sediment where they feed on organic debris normally but infect fish during migrator runs. The toxins from the dinoflagellate also affect humans, causing skin irritation, breathing difficulties and memory loss. The fish-killing forms of Pfiesteria tended to be associated with high nutrient flows into waters from agricultural and urban waste. The identity of the o

Deadly Tide Could Threaten Island
Life Form Is Toxic To Fish and Humans
By KERRY SULLIVAN
One foggy morning in 1991 Dr. JoAnn M. Burkholder, a biologist from North Carolina State University got behind the wheel of Her car. Her destination was eastward, following North Carolina Sate Road #70 along the Neuse River toward the small fishing town of Beaufort and the Neuse River estuary.
There were reports of a huge fish kill coming back to the university from fishermen along the river and the Pamlico Sound, Millions of fish were washing up on the shores of the states pristine bays. Most were covered with bleeding sores.
Burkholder stopped for coffee outside of Kingston where State Road #70 crossed the Neuse River. She peered out into the fog. She was one of the few people in the world that actually knew what was happening in the state, and she also knew it was unstoppable.
A monster from the deep had found a home in the bays and estuaries of North Carolina. It was deadly.
It was a shape shifter, being able to change in a microsecond to any of
