I would toss the Lynx square once for each Lynx.įor each generation I would record my results in my stimulation data table, shown below. I continued the experiment doubling the rabbit count for each generation and when each Lynx survived the next generation it would also produce offspring. It took me until generation 5 for my Lynx to actually survive. If no Lynx survived the previous generation then a new one would move in for the next generation. The rabbit population doubles between generation, I multiplied “rabbits remaining” in my data table with each new generation. At this point I removed the Lynx and tallies into my data table for the first generation. In order for the Lynx to survive it must capture at least three rabbits when tossed into the area. I began with 3 rabbits in my box, and only 1 predator lynx.Īs you can tell, the predator has little chance of survival when the area is so bleak with rabbits. The ultimate procedure should take place within this boxed region where both the rabbits and lynx will roam. I then used a green sheet of paper, cut into strips that I would build into a 12″ by 12″ box for both the predator and prey to live. I then made sure to designate the Lynx from the Rabbits by putting its square on a piece of cardboard and neon orange paper, this way, when in my square space I would definitely be able to showcase the number of Rabbit’s to Lynx. I began by printing and cutting the sheets of 1-inch rabbit and lynx squares as shown in the picture.

Predator-Prey Simulation Data Spreadsheet.Lynx (paper square on 3-inch cardboard square in orange).5 sheets of printed rabbits (a total of 310 1-inch squares).1 colored piece of construction paper (made into 12″ by 12″ box).Predators increase when prey are abundant, henceforth, preys are driven to low numbers by predation, the predators decline while the prey recover. For example, if prey doubles according to each predator then there will continue to be prey, however, if each predator is doubling at the same speed as each prey, the ultimate outcome is an abundance of predators and the lack of prey to stay alive. If the reproductive rate of the prey is increased then the number of predators must stay relatively the same in order for the ecosystem to remain in balance. In this lab my plan is to manipulate the three variables listed above in order to determine how they affect the overall predator and prey populations. The number of prey eaten by each predator.Three factors can affect the cycling of predator and prey numbers. In a stable ecosystem, the number of predators and the number of prey fluctuate, but remain relatively constant.
