7. The outcome of competition between two species for a common resource can be predicted if we know the carrying capacity and competition coefficients of each species. For Species 1, K₁ = 75 and a = 2. For Species 2, K2 = 90 and ß = 3. Use this plot of both species' zero population growth isoclines to predict the outcome of competition in the following scenarios - list whether the population of each species is expected to grow or decline. 100 90 80 70 60 250 40 30 20 10 0 0 20 40 N1 a. 10 of Species 1, 10 of Species 2 b. 40 of Species 1, 10 of Species 2 c. 60 of Species 1, 70 of Species 2 d. 12 of Species 1, 50 of Species 2 60 80 -Species 2 -Species 1
8. Consider another pair of species. For Species 1, K₁ = 125 and a = 0.5. For Species 2, K₂ = 80 and B=0.4. This plot shows both species' zero population growth isoclines. 300 250 200 150 100 50 0 0 50 100 150 200 250 N1 - Species 2 - Species 1 a. What is the expected outcome of competition in the scenario presented here? Consider the equilibrium point for these populations (that is, will there be a winner) and how you expect it to differ from the scenario presented in #7. b. In a scenario like this, do you expect intraspecific or interspecific competition to be more intense for these species?
