Qn a.
b.
If all parameters (r,c,a,m) remains stable, prey population will decline overtime.
c.
Predator population would expected to decline overtime.
I need help with parts a-c if possible, thank you! 5. Assume a predator and its...
Assume a predator and its prey are interacting according to the basic Lotka-Volterra model. The prey population size is 1000, the predator population size is 10, the prey population’s intrinsic rate of growth is 0.1, the predator’s capture efficiency is 0.01, the predator’s assimilation efficiency is 0.2, and the predator’s mortality rate is 0.3. a. Under these conditions, what are the instantaneous growth rates of the prey and predator populations? b. If r, c, a, and m remain stable, which...
have I solved these correctly? (Lotka-Volterra model) Numbered Suppose that porcupines are the only prey and available food source for fisher, and that the predator-prey interaction follows Lotka-Volterra dynamics. The mortality rate of fisher in the absence of porcupines is 0.2 per week, and the intrinsic growth rate of porcupine is 0.3 per week. The capture efficiency of porcupine by fisher is 0.002, and the efficiency at which porcupine biomass is converted to fisher offspring is 0.1. 3a. If there...
Suppose that a lizard species eats only one type of insect and the populations follow Lotka–Volterra dynamics. The intrinsic growth rate of insects in the absence of predators is 0.2 per week, and the mortality rate of the lizards in the absence of insects is 0.05 per week. The capture efficiency rate is 0.002, and the efficiency at which insect biomass is converted into predator biomass is 0.2. The lizard population will increase only if the number of insects is...
3. The graph below has axes to show the population sizes of a predator and its prey. The dashed lines are the predator and prey isoclines. Prey Population Starting at the circle, draw in what will happen to the two populations if they are following the pattern in the Lotka-Volterra model of predation. (Remember that BOTH predator and prey numbers are represented by a point on the graph.) Use a series of arrows to show what happens. 2. Imagine two...
