Contour 2b. Relationship between N and you may Y (kept panel) and you can F and you can Y (right panel) when holding potential K alter 5000 and you can 25000 during the Schaefer model
Shape 3. Twenty years simulator of one’s count for the inventory Letter and you will cash Rev when holding strength K fluctuated. Intrinsic growth rate roentgen is ongoing (0.8) and you can a great = 5.
Contour cuatro. A: K is actually constant (15000), r fluctuated out-of 0.2 through step one.cuatro and you will F was set-to roentgen /2. B: K is actually constant, r fluctuated and you will F was set-to lingering (0.4). C: K fluctuated and you may roentgen is ongoing (0.8). Right here, fishing capacity was multiplied by q and you will yield is actually divided by the one hundred.
The newest bionomic equilibrium part from F where Prof =0 at the low stock top F eq (low) ( K =5000, r =0.8) and you can high stock level F eq (high) ( K =twenty five one hundred thousand, r =0.8) on updates one a beneficial = 5 was basically 0.08 and you can 0.66, respectively (Desk step one).
