The result, Geographic Ecology: Styles from the Distribution of Species, was printed Soon in advance of his Demise the following 12 months. In addition to a summation of labor presently finished, Geographic Ecology was a prospectus of work continue to to get performed in the sector. MacArthur died of renal most cancers in Princeton, New Jersey, on November 1, 1972, with the age of forty-two.
