About the author
Born in Beith, Ayrshire, on 17 January 1870, James Johnstone became known for his work in marine biology and oceanography. He studied the food relationships within the sea and is remembered for treating marine life as part of an interconnected ecosystem rather than a set of isolated species.
He worked in Liverpool, where his research was closely tied to the scientific study of fisheries and coastal waters. That combination of field observation and broader ecological thinking made his work important in the early development of marine science.
Johnstone died in Liverpool in 1932. Reliable biographical information available online is fairly brief, but the surviving record shows a scientist whose work helped shape modern ways of understanding life in the oceans.
