Robert Helmer MacArthur (April 7, 1930 – November 1, 1972) was a Canadian-born American ecologist who made a major impact on many areas of community and population ecology. He is considered to be one of the founders of ecology.

👉 Robert MacArthur in the context of E. O. Wilson
Edward Osborne Wilson ForMemRS (June 10, 1929 – December 26, 2021) was an American biologist, naturalist, ecologist, and entomologist known for developing the field of sociobiology.
Born in Alabama, Wilson found an early interest in nature and frequented the outdoors. At age seven, he was partially blinded in a fishing accident; due to his reduced sight, Wilson resolved to study entomology. After graduating from the University of Alabama, he earned his doctorate at Harvard University, where he distinguished himself in multiple fields. In 1956, he co-authored a paper defining the theory of character displacement. In 1967, he developed the theory of island biogeography with Robert MacArthur.

Robert MacArthur in the context of Insular biogeography
Insular biogeography or island biogeography is a field within biogeography that examines the factors that affect the species richness and diversification of isolated natural communities. The theory was originally developed to explain the pattern of the species–area relationship occurring in oceanic islands. Under either name it is now used in reference to any ecosystem (present or past) that is isolated due to being surrounded by unlike ecosystems, and has been extended to mountain peaks, seamounts, oases, fragmented forests, and even natural habitats isolated by human land development. The field was started in the 1960s by the ecologists Robert H. MacArthur and E. O. Wilson, who coined the term island biogeography in their inaugural contribution to Princeton's Monograph in Population Biology series, which attempted to predict the number of species that would exist on a newly created island.
