Egbert Giles Leigh

Early life and education When he was a young man, Leigh's initial interests had him drawn to topics of history. A biology teacher he had in the 10th grade changed that by shifting his interests to that of biology. From then on, he pursued an education in biology, but still incorporated his initial interest of history into his studies. Leigh received his B.A. degree in mathematics from Princeton University in 1962 and his Ph.D. in biology from Yale University in 1966 while studying under G. Evelyn Hutchinson. He also looks to answer the question of why there are such an abundance and diversity of trees in tropical ecosystems and has been involved in research regarding evolutionary biogeography of islands, such as Madagascar and the Smithsonian Tropical Research Institute's Barro Colorado Island.

Barro Colorado Island, a “Nature Monument”

In the world of science, Barro Colorado Island is considered one of the most famous tropical forests in the world due to the intensity in which its ecosystem has been studied. Research on the island has been under the supervision of the Smithsonian since the mid-1960s, which is when the Smithsonian Tropical Research Institute was formed. Leigh has been part of long-term forest and climate monitoring studies, which were implemented by the Smithsonian Tropical Research Institute during its formation and continue to present day. However, his work on the island has consisted of mainly synthesizing other people's data vs doing his own field work.

Sexual harassment In 2021, Leigh admitted to Buzzfeed News that he sexually harassed colleagues throughout his time as a field researcher at the Smithsonian Tropical Research Institute. Among other items, Leigh admitted to sexually obsessing over junior colleagues, discussing explicit details of sexual acts in professional settings, and greeting at least one female student under his supervision by "lifting her up by the waist, pressing his body against hers, and leaning back".

Notable publications EG Leigh Jr. 2017. Cooperation, Evolution of. Reference Module in Life Sciences, Elsevier.

This paper synthesizes much of Leigh's research over the years on the evolution of cooperation. It addresses how cooperation evolves by elimination of cheating behavior, which does not benefit the common good.

EG Leigh Jr. 2010. The group selection controversy. Journal of Evolutionary Biology 23: 6–19.

In this paper, Leigh summarizes the debate of whether or not Darwinian natural selection supports cooperation in nature. He uses his own research and the research of other scientists to support a stance that states there is a relationship between natural selection and cooperation.

EG Leigh Jr. 2008. Tropical forest ecology: sterile or virgin for theoreticians? pp. 121–144 in W. P. Carson and S. Schnitzer, eds. Tropical Forest Community Ecology. Wiley-Blackwell.

The significance of this paper lies in Leigh's use of mathematical theory to analyze forest ecology and its spatial arrangements.

Leigh, E., & Ziegler, C. (2016). A Magic Web: The Tropical Forest of Barro Colorado Island (2nd ed.). Washington, D.C.: Smithsonian Institution Scholarly Press.

This publication is one of Leigh's most well-known works due to the narrative it gives about the scientific endeavors that occurred on Barro Colorado Island. Coupled with Ziegler's phenomenal photography, this book allows people to visit the island from the comfort of their living rooms and gain an understanding of the important research happening there.

Leigh, E. (1999). Tropical Forest Ecology: A View from Barro Colorado Island. New York, New York: Oxford University Press.

Another well-known publication by Leigh, this book describes the relationship of ecosystem biology to evolutionary biology and population/community ecology. It uses Barro Colorado Island as the example ecosystem to depict these relationships.
