VERMILLION, S.D. – John Delong, professor of biological sciences at the University of Nebraska-Lincoln, delivered a lecture titled “Eco-evolutionary dynamics and the evolution of body size,” at the University of South Dakota campus April 3.
Delong, whose research has spanned from raptors to wolf spiders, studies how mechanical influences affect body size in predator-prey relationships.
“Obviously, bigger predators eat bigger prey, but when you change the body size, you change how the community interacts,” said Delong.
Delong hopes his research will create a better understanding of how environmental factors influence growth and eventually evolutionary change.
“All organisms demand resources and the environment supplies those resources. The amount demanded increases as organisms grow,” said Delong.
