What is the difference between the exponential (J-shaped) and the logistic growth model (s-shaped)? Select all that apply Small populations grow more slowly in the logistic model because it assumes that there are fewer individuals capable of producing offspring The logistic growth model reaches and inflection point because resources can become limiting in large populations The exponential growth model assumes that there are no limitations of resources on a population no matter how large it gets Carrying capacity is only a component in the exponential growth model, not in the logistic growth model if populations were a metaphor for money, and you wanted to maximize your return on investment, you would choose the logistic growth model

What does the growth rate of 0.7 mean in relation to r=(birth-death)+(immigration-emigration) What does the growth rate of 1 mean in relation to r=(birth-death)+(immigration-emigration) What happens to the population when r is greater than 1? What happens to the the population when r is equal to 1? What happens to the population when r is less than 1? Provide and explain the factors that lead to each type of distributions.
The per capita birth (b) and death (d) rates are measured for two populations across a range of population sizes in the attached figure. The equation for exponential growth rate is dN/dt=rN where the per capita growth rate is r=(b-d). The equation for logistic population growth rate is dN/dt=rN(1-N/K). With logistic growth, r varies as a function of the population size with density-dependent birth and/or death rates. See attached image If the death rate decreased, what would happen to the population trajectory for population A? a) increase faster b) increase slower c) decrease faster d) decrease slower
In the logistic model of population growth what are N and K and what happens if N>K and explain why. Ho w is the population growth affected if N=K?
If the population of 150 squirrels at UofL has 15 births this year, what is the per capita birth rate? - 0.1 squirrels/yr/squirrel If the population of 150 squirrels at UofL has 10 deaths this year, what is per capita death rate? - 0.067 squirrels/yr/squirrel Calculate the intrinsic rate of increase for this squirrel population, using your answers to the questions above. - 0.03 squirrels/yr/squirrel Between having plenty of shelter in the trees and scavenging through the campus garbage, UofL squirrels have seemingly unlimited resources. Using the information you've calculated so far, determine the growth increment for the coming year for the UofL squirrel population. - 4.5 squirrels/yr Let's say that, after you calculated your predictions for unlimited growth of the UofL squirrel populations in the questions above, a bad storm comes through campus and wipes out half the trees! Now, the growth of the population of squirrels becomes limited. There are still 150 squirrels, but the…
If each adult female powerful owl produces 1 female juvenile (F) each year, the adult survival rate (Sa) is 0.8, the juvenile survival rate (Sj) is 0.4, and the population is N2022=1400 adult females and 1400 juvenile females in 2022, what will be the female population size in 2027 (N2027)? Show your calculations. (hint: use excel to set up a model and check your work)
A few plant-eating salamanders manage to float on a log to a large island in the Pacific that did not have any other salamander species previously. The salamanders find the island has abundant plants for food and no predators. On average, a salamander has four offspring per year and lives for one year. Refer to the equation for the logistic growth model if you were modeling salamnder population growth with this logistic growth equation, during the first few years, a) N<K b) N=K c) N>K d) there is no relationship between N and K
Why does the exponential model of population growth produce a curve shaped like a J?
A population that did not grow in close relation to the amount of resources available in the environment, and dramatically overshot the carrying capacity, would experience: A. logistic growth, such as shown on the S-shaped curve B. exponential growth, such as shown on the J-shaped curve C. unpredictable growth, such as shown on the ?-shaped curve D. exponential growth, such as shown on the S-shaped curve E.logistic growth, such as shown on the J-shaped curve
You are studying a density - dependent turtle population that has the following relationships for the birth rate b’ and the death rate d’ as a function of population size (N) : b’ = 0.10 + 0.03 N - 0.0005 N ^2 d’ = 0.20 + 0.01 N Plot these functions in the same graph and discuss the population dynamics of the turtle. How does this model differ from the simple logistic model with linear birth and death functions?

Which growth model would you expect to see in a stable population? Select one: Exponential Speculative Factorial Logistic
The discrete logistic function (the one you can solve with your calculator) has a time lag built in = one generation. What would a greater time lag do to the outcome? increase the chances of population exceeding K decrease the chances of population exceeding K slow down population growth by decreasing r increase population growth by increasing r it would have little/no effect under all circumstances
