In his small lifetime (b. 1930–d. 1972), Robert MacArthur was a remarkably influential architect of contemporary ecology. He was, up to ca any individual, answerable for bringing theoretical populace biology into mainstream ecology at a time when numerous empirical ecologists were brazenly hostile to principle. He inquired broadly, read through extensively, and wrote clearly and concisely. dr robert macarthur He was an enthusiastic naturalist and an analytical thinker; but more importantly, he blended these roles, making use of his mathematical insights in the field and being encouraged by observation in his theoretical get the job done.
