Exаmine the fоllоwing figure, reаd the cаptiоn, and answer the question. Figure 1. Hypothesized species interactions among lions, plains zebra, Jackson's hartebeest, and cattle in Laikipia, Kenya. (A) Zebra populations are controlled bottom-up by rainfall, are the primary prey of lions, and support a growing population of lions since the cessation of lethal control in the late-1980s. Although they are less abundant than zebra, hartebeest are selectively killed by lions and are controlled top-down, such that hartebeest incur negative, indirect impacts from zebra via lions. (B) Cattle are corralled overnight in bomas where they deposit dung and urine for a period of ca. 1 month. (C) After abandonment, dung and urine break down over the course of 2–3 years, creating nutrient-rich forage in glades where zebra aggregate, but not hartebeest. This creates spatial separation between zebra and hartebeest, and potentially a refuge from predation if lions target hunting activity toward areas where zebra are abundant. (D) Survival rates and 90% confidence intervals from Cox proportional hazards models for hartebeest with territories containing vs. lacking glades. Modified from: Ng'weno et al. 2019 Behavioral and Evolutionary Ecology, 7: 123 You can calculate the cost of apparent-competition by subtracting the survival rate when glades are present (dotted line Figure 1D) from the survival rate when glades are not present (solid line, Figure 1D). After one year the cost of apparent-competition is approximately a
