" The rate of this process decreases with increasing area in Macarthur and Wilson's island biogeography model.
Four positive feedback cycles that increase the likelihood of this process occurring were proposed by Gilpin and Soulé. Jackson and Sax introduced the concept of an "Immigration Credit" to contrast with a term that describes the future occurrence of this process, which is called its namesake "debt." The rate of this process decreases with increasing area in Macarthur and Wilson's island biogeography model. When this process occurs in one of several populations, it is called its (*) "local" form. After the Nile Perch's introduction into Lake Victoria, there was a dramatic rise in this process among cichlids, and organisms that have experienced this process include the golden toad and the great auk. For 10 points, name this process that occurs when a species' population falls to zero.
