QUESTIONS1.What species interactions give rise to uniform distribution pattern? Aggregate? Random?2. What is the most common type of distribution found in nature? What are the reasons for this?3. In addition to population distribution, other characteristics of a population include the intrinsic rate ofpopulation growth (r) and the carrying capacity (K). Define these two tterms4.

Bayesian updating can be a useful tool for thinking about the development of behavior. Imagine the following scenario with respect to an animal’s knowledge of the average density of food in patches in their environment. Which of the following is the most accurate interpretation of this Bayesian view of this animal? Their environment is much richer in food resources than expected Their confidence in their assessment of the state of the environment is greater after they go out and sample the world Their environment is less rich than expected – perhaps there is a drought that has caused a crash in food availability relative to historical conditions All of the above
. Simulations 4-6 had lower density of birds (more spacing), how did this influence their ability to escape predation? With more spacing, which number of Junco’s was most advantageous (4, 8, and 16)? Ecologically explain this result. If this flock of birds occurred in an area with low food availability what flock density would you predict? Explain how food availability impacts flock size/competition. Was there a relationship between prop. Vigilance (proportion of birds looking up right before Hawk attack) and the rate at which they escaped predation? Was there a relationship between Mean vigilance (average number of birds looking up each tick) and the rate at which the Junco’s the escaped predation? Was there a relationship between Mean vigilance and the number of birds in the flock?
11. To increase the amount of energy available from food, which of the following strategies can people pursue? a. Eat earlier in the food chain. b. Eat farther along the food chain. Eat more meat products. Drink more water. e. Take more vitamins C. d. 12. According to the demographic transition model, what happens to population size as societies move from agricultural production to industrialization? a. It increases as death rates exceed birth rates. b. It decreases as death rates exceed birth rates. c. It increases as birth rates exceed death rates. d. It stabilizes with no changes in birth and death rates. e. It stabilizes as birth and death rates are balanced
1. Giving up density is a way to measure the conditions under which an animal is willing to experience risks in feeding. One way to approach an GUD experiment is to mix food in with inedible particles, then to measure what percent of the mix is food when an animal stops collecting or eating food. How could this method be used to study optimal foraging conditions? 2 wk
4. (4) In laboratory experiments studying predator-prey interactions, Gause demonstrated that sediments were required to prevent the prey from becoming extinct and that periodic additions of new individuals of prey and predator were necessary to obtain repeatable oscillations in these two populations. Discuss how realistic these laboratory manipulations are compared to what we know about natural populations.
4 Use the drop-down menus to complete the statements about the birds. The changed environment selected For Against the birds with smaller beaks. The population of birds with smaller beaks increased decreased because of an increase decrease in competition over small seeds.
5) Peters et al. (2016) examined the impact of different human diet scenarios on the carrying capacity of the human population in the United States. The "baseline diet" is the current average diet of Americans which includes a high proportion of meat and dairy products. The study compared the baseline diet to a vegetarian diet (which includes both egg and dairy products) and five omnivore diets. The 100% omnivore diet scenario proposed that 100% of Americans are eating a healthy diet including meat, dairy, and vegetables with the primary source of protein coming from meat products. The other omnivore diet scenarios decrease the proportion of US population eating meat products and increasing the proportion of people on a vegetarian diet (no meat products consumed). For instance, the 60% omnivore diet scenario assumes that 40% of the US population is vegetarian. Below is a graph showing the predicted carrying capacity of the United States under these different diet scenarios. Human…
