Question

PLEASE explain the reasoning behind parts B and C.
What are the expected equilibrium population sizes for each species?

Question 3. You are studying interspecific interactions between brown and black turban snails. For the brown snails, 150 and125; for the black snails, KBlak 120 and KBlak/B 90. Suppose the initial population sizes are 15 brown snails and 75 black snails. 150 120 90 60 30 Me 0 30 60 90 120 150 NBrown A. Complete the phase plane above by adding the zero growth isoclines for each species. B. What are the expected short-term (one time step) dynamics for the two populations (i.e., do they increase, decrease, or stay the same)? C. What are the expected long-term (equilibrium) conditions for the two populations (i.e., do they go extinct, reach carrying capacity, or coexist)?

Explanation / Answer

B. According to the graphical representation N Brown increases and N Black decreases.

C.These would probably coexistas for carrying capacity the grph must have acquired horizontal line anywhere which is not present here so the carrying capacity option s ruled out.They also wont extinct as for extinction many other forces are involved too.
