Dr. Glover and colleagues published their findings on the bigheaded carp invasion front in Biological Invasions. This multiyear study used novel hydroacoustic techniques to evaluate changes in the abundance and distribution of these invasive species and evaluated the role that intense harvest has played to reduce the potential for spreading.
