Question

ich of the foowing is corret? Refer to the figure below of Lotka-Volterra Competition. Which of the following is correct? Competition.png OA. Both species 1 and species 2 can be at stable equilibrium points at the same time; coexistence. OB. Species 1 outcompetes species 2 because it has a lower carrying capacity than the effect of species 2 on species 1's carrying capacity. ° C. Species 2 outcompetes species l because it has a higher carrying capacity than the effect of species 1 on species 2's carrying capacity. D. Both species are regulating the population abundance of one another. O E. BothC and D

Explanation / Answer

The isoclines of the two species cross one another. Here, the carrying capacity of species 1 (K1) is higher than the carrying capacity of species 2 divided by the competition coefficient (K2/), and the carrying capacity of species 2 (K2) is higher than the carrying capacity of species 1 divided by the competition coefficient (K1/). Below both isoclines and above both isoclines the populations increase or decrease, and there is an unstable equilibrium point (closed circle) where the isoclines intersect. The points above the yellow line (species 2 isocline) and below the solid green line (species 1 isocline), the outcome is competitive exclusion of species 2 by species 1can be observed. The points above the green line (species 1 isocline) and below the yellow line (species 2 isocline), the outcome is competitive exclusion of species 1 by species 2 can be observed. The two stable equilibrium points are again represented by open circles. In this scenario, the outcome depends on the initial abundances of the two species. Hence, option D is correct.
