Marginal Value Theorem
The marginal value theorem (MVT) usually describes the behavior of an optimally foraging individual in a patchy system, but it can also be applied to other situations in which organisms face diminishing returns. The resources (often food) in patchy systems are located in discrete patches separated by areas with no resources. Due to the resource-free space, animals must spend time traveling between patches.

Famous quotes containing the words marginal and/or theorem:
“Of course I’m a black writer.... I’m not just a black writer, but categories like black writer, woman writer and Latin American writer aren’t marginal anymore. We have to acknowledge that the thing we call “literature” is more pluralistic now, just as society ought to be. The melting pot never worked. We ought to be able to accept on equal terms everybody from the Hassidim to Walter Lippmann, from the Rastafarians to Ralph Bunche.”
—Toni Morrison (b. 1931)
“To insure the adoration of a theorem for any length of time, faith is not enough, a police force is needed as well.”
—Albert Camus (1913–1960)
