01-Richard Levins at 85th Birthday Symposium Tribute Dinner 5-23-2015

Richard Levins (June 1, 1930 – January 19, 2016) was an American ecologist, evolutionary biologist, and mathematician who made significant contributions to the fields of population biology, theoretical ecology, and complex systems. He is best known for his work on metapopulation theory, evolutionary theory, and the application of mathematical modeling to ecological and evolutionary problems.

Early Life and Education

Richard Levins was born in Brooklyn, New York City. He developed an early interest in natural sciences and pursued his undergraduate studies at Cornell University. He later completed his Ph.D. in zoology at Columbia University.

Academic Career

Levins held academic positions at several institutions, including the University of Puerto Rico and Harvard University. At Harvard, he was a member of the Harvard T.H. Chan School of Public Health, where he worked on the application of ecological principles to public health issues.

Contributions to Ecology and Evolution

Levins is renowned for his development of the metapopulation concept, which describes a group of spatially separated populations of the same species that interact through migration. This concept has become a fundamental framework in conservation biology and landscape ecology.

He also made significant contributions to evolutionary theory, particularly in the areas of adaptive landscapes and fitness landscapes. Levins' work emphasized the importance of considering multiple factors and their interactions in understanding evolutionary processes.

Mathematical Modeling

Levins was a pioneer in the use of mathematical modeling in ecology and evolutionary biology. His influential 1966 paper, "The Strategy of Model Building in Population Biology," outlined the principles of constructing and using models to understand complex biological systems. He advocated for the use of simplified models to capture the essential features of biological phenomena.

Political and Social Engagement

Levins was also known for his political activism. He was a committed Marxist and believed that scientific research should be used to address social and environmental issues. He was involved in various movements advocating for social justice and environmental sustainability.

Awards and Honors

Throughout his career, Levins received numerous awards and honors for his contributions to science, including the Sewall Wright Award from the American Society of Naturalists and the Robert H. MacArthur Award from the Ecological Society of America.
