In 1992, William Rees developed a method of measuring environmental impact called “appropriated [this quantity]” or ecological footprint. The Levins model used to study patch dynamics represents this quantity as “one minus the extinction rate over the colonization rate.” This quantity and an “unstable” threshold value denoted A appear as denominators in equations modelling the Allee effect. A capital letter denoting this quantity names a life history strategy followed by organisms that rear a (*) small (-5[1])number (-5[1])of slow-maturing offspring and live in crowded conditions. (10[1])During logistic growth, a population initially grows rapidly and then stabilizes as it approaches (10[1])this quantity (10[2])denoted (10[1])capital (10[1])K. For 10 points, (10[1])name this maximum population size (10[1])that an environment can support. ■END■ (10[1])
