spend midday resting in any available shade. If they and dle. Trees and bushes are scarce in many parts of the island, so shade is often scarce too. Are the sun and the sh density dependent or density independent factors? (Try to find the priority information here, there are some distractor Think about your definitions for the words below.) A. density dependent B. density independent 13. Which of the following statements is correct? A. Population size of predators increases when their prey's population is low. B. Competition for resources is density-independent when food is plentiful. C. Discase is density-dependent because spreading occurs more easily when a population is closer together. D. A change in average temperature is a density-dependent factor because fewer organisms can acclimate to variations in temperature.

Then, revise the model to consider harvesting the whales as a percentage of rM. Give various values for this percentage that lead to extinction and other values that lead to in- creases in the population.

Expat Med @DrExpat_ 4. Respond to this tweet on the right using mathematical evidence from the Lotka-Volterra model of predator-prey interactions. Draw a graph to illustrate what the Roomba's population growth rate would look like in the wild in the absence of predation (*assuming the Roomba was capable of reproduction in its new habitat).

Graph Analysis - Predator-Prey Graph Isle Royale National Park on a remote island was established in 1940, and designated a wilderness area in 1976. The only mode of transportation available is by boat or seaplane. Moose first arrived at Isle Royale around 1900. The moose population tends to increase in years with mild winters, early spring green-up, abundant winter forage, low wolf numbers and low levels of tick infestation. Wolves first arrived at the island on an ice bridge from Canada in 1940. Disease has also influenced the wolf population. Between 1980 and 1982, the wolf population declined from 50 to 14, due to canine parvovirus.

Figure 19.6 If the major food source of seals declines due to pollution or overfishing, which of the following would likely occur? a. The carrying capacity of seals would decrease, as would the seal population. b. The carrying capacity of seals would decrease, but the seal population would remain the same. c. The number of seal deaths would increase, but the number of births would also increase, so the population size would remain the same. d. The carrying capacity of seals would remain the same, but the population of seals would decrease.
Figure 45.10b If the major food source of the seals declines due to pollution or overfishing, which of the following would likely occur? The carrying capacity of seals would decrease, as would the seal population. The carrying capacity of seals would decrease, but the seal population would remain the same. The number of seal deaths would increase but the number of births would also increase, so the population size would remain the same. The carrying capacity of seals would remain the same, but the population of seals would decrease.
Match each term with its most suitable description. _____ carrying capacity a. maximum rate or increase per individual under ideal conditions _____ exponential growth b. population growth plots out as an S-shaped curve _____ biotic potential c. maximum number or individuals sustainable by the resources in a given environment _____ limiting factor d. population growth plots out as a J-shaped curve _____ logistic growth e. essential resource that restricts population growth when scarce
Draw and label graphs (including zero-growth isoclines) showing the predicted behavior of the Lotka-Volterra predator/prey equations if we assume prey growth follows and exponential growth model. Show how the graphs would change of the prey follow a logistic growth model.
