Graph 3 will be a triple axes line graph with the data for both predator and prey for all trials. The predator data will be plotted on the left hand y axis and the prey data will be plotted on the right hand y axis. Use the same scale that you used on graphs 1 and 2. Graph 4 will be a bar graph showing the number of deaths for each round or trial. Each trial will have two bars, one for predators and one for prey.
The growth of the predator population will depend on the population sizes of the predators and prey, and the ability of the predators to successfully catch prey. We represent this by $\beta xy$. The equation for predators becomes: $$\frac {\mathrm{d}y}{\mathrm{d}t}=\beta xy-\gamma y =y(\beta x -\gamma)$$ Using the Equations

Mar 07, 2015 · 1. Introduction. Predators can impact their prey and smaller predators (mesopredators) via two mechanisms: consumptive (i.e. lethal) effects that occur through direct killing and non-consumptive (i.e. non-lethal) effects that become manifest as prey and competitors shift their phenotypes and habitat use in response to risks associated with predation [1,2].

• To graph the data obtained. BACKGROUND INFORMATION Predator organisms feed upon other organisms, called prey. The predators depend on the populations of these prey organisms. The number of predator organisms depends on the numbers of the prey. The number of prey is limited by the number of predators that feed on them.

Major assumption – predators determine abundance of their prey 1. Predators actually control abundance of prey and keep numbers below what they could be 2. Predators only remove “doomed surplus”. Individuals that would likely die for other reasons. Thus removing predators will have no effect on population of prey.
In the wild there are two types of animals: the hunters and the hunted. A good predator is always on the prowl for fresh prey. What can an animal do to stay off of the menu? To survive, some animals use camouflage so they can better blend in with their surroundings. In this science project, you will be the hungry predator hunting for M&M® prey.
The graph that I posted is also pretty suspicious just because of the way it was laid out. I think it might be quite misleading, but that is hard to say w/o looking at the real data.

Predator-Prey Cycles. It is logical to expect the two populations to fluctuate in response to the density of one another. When the prey species is numerous, the number of predators will increase because there is more food to feed them and a higher population can be supported with available resources. Taken (and modified) from http://www.biologycorner.com/worksheets/predator_prey_graphing.html The results of this program are shown in the following table. The “Deer Population Change” is the number of deer born minus the number of deer that died during that year. Fill out the last column for each year (the first has been calculated for you).

Abstract. Predators can affect prey populations through changes in traits that reduce predation risk. These trait changes (nonconsumptive effects, NCEs) can be energetically costly and cause reduced prey activity, growth, fecundity, and survival. The strength of nonconsumptive effects may vary with two functional characteristics of predators ... The prey species has an unlimited food supply and no threat to its growth other than the specific predator. If there were no predators, the second assumption would imply that the prey species grows exponentially, i.e., if x = x(t) is the size of the prey population at time t, then we would have dx/dt = ax.
