This controllable behavior must be absent for a population to be in Hardy-Weinberg equilibrium.
V.A. Drake devised a model of this phenomenon that includes an "arena" in which it takes place, a "syndrome" of traits enabling it, and a genetic complex underlying the syndrome. The adjective "Lessepsian" is appended to the name of this phenomenon whenever it is affected by man-made structures. George S. Myers coined the term "diadromous" to more broadly describe organisms that exhibit this behavior, than the contrasting terms "anadromous" and "catadromous." Some lake and ocean-dwelling organisms such as copepods undergo a diel, or diurnal, (*) vertical type of this behavior, and several birds undergo a "reverse" type. Methods such as pop-up satellite archival tag track this behavior using the Argos system. This controllable behavior must be absent for a population to be in Hardy-Weinberg equilibrium. A widely-studied instance of this behavior begins in September or October among monarch butterflies. For 10 points, name this large-scale, long-distance movement of animals.
