When a quantity like the rabbit population grows exponentially, there is a xed time for which any initial quantity will double in size. We begin with the differential equation \[\dfrac{dP}{dt} = \dfrac{1}{2} P. \label{1}\] Sketch a slope field below as well as a few typical solutions on the axes provided.

If $r$ were really 0.2, what value of $a$ would make the equilibrium be 1000? We rank these hotels, restaurants, and attractions by balancing reviews from our members with how close they are to this location. What happens when costs exceed budget, whether due to materials or labor pricing changes? One difficulty is that you don't know how many rabbits you should remove each month. The proposed rabbit control strategy must be represented by a discrete dynamical system similar to \eqref{fixedremoval} that leaves rabbit reproduction rate $r$ and initial population size $p_0$ as unknown parameters.

The logistic model assumes that resources and space limit the growth of a population and that these factors determine the maximum number of individuals that can be sustained over time. Based on this information, you postulate the following model for rabbit population growth. Also, if the current population size $p_0$ is already much larger than 1000, will this strategy work to bring the population size down to around 1000? Are there any important considerations or concerns that you know of or that might come up in the future with this project? Reported resources will be reviewed by our team. A comparison of the simulation results to real data is given, together with the graphical representations. endobj You can change $r$ by typing a number in its box.

Feeling pretty smug that you've got everything under control, you are ready to test your model and demonstrate how well this harvesting strategy will work to control the rabbit population. You can use the mathematical model to test out the proposed strategy using different assumptions regarding the parameters, without risking embarrassment if they fail. The activity will reinforce the concepts of exponential growth, logistic growth and carrying capacity. In that case, if you start with a population of around $p_0=1000$ rabbits, will the population stay there? (Types of functions) The Quarterly Review of Biology.

Oh, that was the other unknown parameter you couldn't think of. In the Rabbit Population by Season Gizmo, you will see howdifferent factors influence how a rabbit population growsand changes. You have no idea what to use for the initial population size $p_0$, other than that you can tell there are quite a few more than a thousand rabbits around.

After creating this model, you decide to replace the fixed fraction of 0.2 with a parameter $r$ that you could change, to explore what would happen if the rabbit counters were a bit off in their estimate of the growth rate. << /S /GoTo /D (subsection.3.4) >> Click here to play the game. endobj You calculate that a population of about a thousand rabbits would allow occasional rabbit sightings while still minimizing the damage to gardens. endobj A simple way to accomplish this variable control is to make $h(p_t)$ be proportional to $p_t$, letting If you are really clever, you might find a case that seems to work OK by making $a$ be negative. For details on Logistic population growth, see our article on The Logistic Differential Equation.

Spring. ), and allow the simulation to run for one year. Now, you don't have the parameter $a$ any more, but you just have the parameter $b$ (since the evolution rule is now $p_{t+1}-p_t = r p_t-bp_t$). Your revised model is \end{gather}. 34 0 obj But, maybe it is still close enough to 1000. At time 0, the population size is $p_0$, which you can change by dragging the blue dot or typing a number in the box. I suppose you could drop off new rabbits in that case (like with model \eqref{affineremoval} with negative $a$), but you don't want to resort to that. Is this a step in the right direction? (Unfortunately, this value of $a$ is likely to depend on $r$.). It turns out many people, especially children, like having at least some rabbits around, so FACT has been asked to find a way to maintain a steady but small population of rabbits on Foxless Island. Their growth rate is 1.0. Sofia_Macias_-_M1_L1_Rabbit_Population_by_Season_-_Biology_H_Online. Writing the computer program helped you remember that you needed a number for $p_0$ to calculate the population sizes at later times. Your problem is to figure out how many rabbits you should remove each month in order to maintain a stable population of around a thousand rabbits. You decide it's time to build another computer program to see what's going on in this case. endobj Is it perfect or does it have some flaws? p_{t+1}-p_t = r p_t-h(p_t). Tables must be numbered, title written in lower case letter (except the first letter) and left justified.

As an aid, the applet does try to calculate equilibria. You realize that just knowing values of equilibria isn't enough to figure out what will happen. endobj With improved AI techniques, a better use of improved NDama bulls can be achieved. The equilibrium values are working out like you calculated. 20 0 obj The reproduction of rabbits is also larger when the population is larger, so the best you can do is exactly balance the reproduction of rabbits (by setting $b=r$), but that is not robust to changes in $r$ nor does it shrink the population size if you start out with way too many rabits.
