Etymology: "Aestivate" is the American spelling of "estivate," a verb meaning to spend the summer in a state of rest or dormancy, much as some animals do. The word comes from Latin "aestivus," meaning "of summer," which is built on "aestas," the Latin word for summer. English took the Latin verb "aestivare" and adapted it into the familiar form we use today. The spelling with "ae" is the older and more classical one, preserving the Latin letters directly, while "estivate" drops the first vowel, following the simplified spelling common in English. Both forms describe the same summer dormancy, and the "ae" spelling is the one most often seen in American dictionaries.
