Questions
1. Which of the following is correct about western burrowing owls?
A. They are active only during the day time, but not at night time.
B. Owls live in grassland habitats that they share with other animals, such as deer, cows, and squirrels.
C. Owls can live as long as 8 -9 years in the wild. D. The burrowing owls leave Colorado and migrate north toward Canada when the breeding season is over.
2. A _______________ trait is defined as any trait that affects birth and death rates because it affects the growth, reproduction, and survival of organisms. A. ecological B. phrenologic C. Life history D. Interaction
3. All of the following are traits of burrowing owls except; A. Burrowing owls make nests in trees, and use burrows in the ground to store food. B. Female owls are about 10 months old when they have their first chicks. C. Females have, on average, 6 chicks per year. D. Other than their last year of life, the owls' death rate is highest in their first year of life.
4. Suppose there are two populations of burrowing owls that you are studying: one in Colorado Springs (COS) and one in Denver (DEN). The environment of both populations is very similar, and in both populations, females can live to be the same maximum age, and tend to die at the same rate at each age. The COS females start breeding at 10 months old, but they can only have 25 chicks in their lifetimes. The DEN females start breeding at 20 months old, but they can have 27 chicks in their lifetimes. Based on this information, what will you expect to observe about population growth of these two populations?
A. The COS population will grow faster than the DEN population. B. The DEN population will grow faster than the COS population. C. The two populations should grow at about the same rate. D. It is not possible to predict how the populations will grow based on this information.
5. What is the explanation for how the populations are growing in the previous question? A. There are too many coyotes in the DEN population, eating the chicks. B. The COS and DEN populations will grow the same because their environments are similar, and they tend to have the same age and death rates. C. DEN grows faster than COS because the females can have more birds in their lifetime, which adds more birds to the population. D. COS grows faster than DEN because there are more chicks being added to the population sooner.
8. Which of the following are biotic factors found in the owls' environment? (Select all that apply.) Group of answer choices coyotes amount of rainfall prey, such as lizards and grasshoppers vegetation
9. Given what you know about burrowing owl activity and population growth, suppose a dog owner lets a dog out during the day time from 7 am - 10 am. The dog likes to hunt owls that are out of the burrow, and is causing the population of birds to decline. As a conservation biologist, you are concerned about the owls, and you talk to the dog owner. The owner insists on letting the dog outside every day. Which of the following actions by the dog owner would have the most positive effect on the owl population? A. Letting the dog outside later in the day (between 11 am and 3 pm). B. Training the dog only to eat owl chicks, and not adults. C. Training the dog to hunt only female owls rather than male owls D. Training the dog to dig more burrows while it is out hunting in the morning.
10. Reflect on the factors that affect population growth in burrowing owls through these activities. If you were a conservation biologist, what one factor would you focus on the most to help protect the owl populations? Your explanation should refer to the population growth graphs under specific conditions.
