Allee was strongly influenced by
Frank R. Lillie, head of the Department of Zoology at the University of Chicago and one of the founders of the Marine Biological Laboratory in Woods Hole, MA. In 1923, Allee began to write a series of papers entitled, Animal Aggregations. Eight years later, he published his findings in a book under the same name. The results of Clyde Allee's research demonstrated the existence of an unconscious drive within species for fellow individuals of the same species. This research helped to prove that under crowding was detrimental to some animals. Allee's Quaker beliefs led to the development of his dedication to show how cooperation is essential in the natural world. This led to the development of the
Allee effect.
Allee effect Allee dedicated his life to researching the benefits of organisms acting in a group rather than as individuals. Through observing groups of organisms, Allee discovered that cooperation is both beneficial and essential in nature. The Allee effect describes the positive correlation between population density and individual fitness of a population or species.
Social Implications Allee's research on social aggregations and the evolution of cooperation coincided with his social activism, religious beliefs, and
opposition to war. Raised as a Quaker, Allee publicly renounced war, which made him a target of harsh criticism and persecution. In the 1940s, Allee argued that his research on the social behaviors of animals provided clear evidence against a biological basis for war. Specifically, he believed that his theory on the sociality of organisms based on cooperation among individuals proved that war was not a natural occurrence. According to Gregg Mitman, Allee saw ecologists as "social healers" who were able to provide a naturalistic foundation for ethics through their research. ==Involvement in other scientific work==
