Simberloff tested this theory on tiny mangrove islets in the Florida Keys. They eradicated all insect species and observed the re-population by new species. Wilson and MacArthur's book The Theory of Island Biogeography became a standard ecology text."
The Theory of Island Biogeography is one of the most important contributions to ecology ever.
He coined the term "biophilia," which essentially posits that humans have an innate attraction to nature. He wrote a book exploring that idea in a book appropriately titled "Biophilia."
He also wrote some stuff he called "sociobiology," essentially about how evolution by natural selection can explain human behavior and culture. It's a bit weird and not related to /out/, so I won't get into it.
