7. DRAW IT You are considering two optimal foraging models for the behavior of a mussel-feeding shorebird, the oystercatcher. In model A, the energetic reward increases solely with mussel size in model B, you take into consideration that larger mussels are more difficult to open. Draw a graph of reward (energy benefit on a scale of 0–10) versus mussel length (scale of 0–70 mm) for each model. Assume that mussels under 10 mm provide no benefit and are ignored by the birds. Also assume that mussels star becoming difficult to open when they reach 40 mm in length and impossible to open when 70 mm long. Considering the graphs you have drawn, indicate what observations and measurements you would want to make in this shorebird's habitat to help determine which model is more accurate.

A predator's foraging behavior can be altered by prey density is different ways (functional responses). While some predators
consume more preys at higher prey density (e.g., spiders), other predators such as pelicans will slowly decrease prey
consumption as prey density increases. What type of functional response will describe a backswimmer (aquatic predatory insect)
that exhibits low prey consumption under low prey density, rapid prey consumption under moderate prey density that slows
down at high prey density?
O Type II
O Type III
O Type I
What is the best description of the original Lotka-Volterra predator-prey model? Nis
prey, P is predator. a is rate of consumption, f is conversion of prey to predator, and
q is the mortality rate of the predator.

- 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 abovearrow_forwardAnimals have evolved a range of strategies to successfully respond to threats and challenges. One of these strategies is the ability to learn. As we discussed, not every animal can learn and there are clear costs and benefits to this strategy. Suggest one benefit of the ability to learn and one potential cost. Briefly explain each. (1-2 sentences for each) Since learning is not universal, under which circumstances would it be most likely be a successful strategy? We discussed a framework that examines the influence of predictability on the success of learning ability. Describe this framework. Make sure you discuss all the available conditions and clearly state under which we would expect learning to be successful and where we would not expect it to be successful. What would be an alternative strategy to regulate behaviour when learning is not suitable? Briefly explain your choice. (2-3 sentences)arrow_forwardNeed help Multiple choice Fewer than 3% of animals engage in direct care of their offspring. When might the benefits of parental care outweigh the costs? Choose the correct option and Explain why you choose that answer. a) All of the options. b) Species that feed on resources with high foraging effort (e.g., smaller insect prey versus larger insect prey). c) Species with highly immature young, for instance those with large brains that have long learning periods. d) Species with limited breeding opportunities.arrow_forward
- Much of animal behaviour theory is rooted in optimality, using this theory and thinking about territory size, construct a well-labeled graph below: sketch two lines (one for costs, one for benefits), with an asterisk (or symbol of your choosing) indicate the theoretical optimal territory size and in one sentence, explain why that particular territory size is optimal . Territory Size Costs/benefitsarrow_forwardIf you adjust each of the four constants, one at a time, by 10%, which seems to have the greatest impact on the simulation output? Examine the Lotka-Volterra equations to explain by this constant makes such a big difference in the predator-prey system. Hint: This constant affects both the birth rate of predators and the death rate of prey.arrow_forwardComparing across animals in the image, do you think there is a major difference in the animals' abilities to solve complex problems like mazes, tool use, etc.?

- The acquisition of memories can be demonstrated in rodents on a T-maze task. In this task, a food reward is placed in one of two arms of a T. Over many trials, a rodent is required to learn which arm contains the reward. In an experiment to determine whether the gene Homeriav is involved in memory, a mouse was trained on a T-maze. The results over five trials of training are shown: a. This task tests both innate and learned behaviors. Describe the innate behavior tested by this task. Explain how innate behaviors contribute to the survival of a species. b. A scientist reviewing this experiment notes that insufficient controls were performed to determine whether mutations in Homer1aV affects the function of physiological systems outside of the nervous system. Identify a physiological system outside of the nervous system that contributes to the performance of this task. Explain how the function of this system contributes to the task. c. Describe how the consumption of food by the rodent…arrow_forwardGreat white sharks prefer marine mammals like seals but can eat a number of other prey items, including birds and fish. According to the table below, what is the critical search time for seals, above which great white sharks should choose to eat an albatross if they encounter one? Prey item: seal (energy = 60 Mcals, handling time = 5 minutes) Prey item: albatross (energy = 10 Mcals, handling time = 2 minutes)arrow_forwardWhat do these results suggest about the role of PKA in insects that are always gregarious? Insects that are always gregarious show an aberrant PKA activation cycle. PKA plays a role in modifying behavior patterns, but not in establishing the patterns. Gregarious insects do not express the PKA protein. PKA affects behavior only in solitary insects.arrow_forward
- P3, Belding's ground squirrels (Spermophilus beldingi) live in closely related groups. When they feed in the open, certain individuals (guard squirrels) watch for predators instead of feeding. The guard squirrels give an alarm call when a predator is sighted, allowing the rest of the group to run to safety. Researchers have noted that, because the alarm call draws attention to the guard, the guard is more likely to be caught by the predator and therefore has a lower survival rate in comparison with the other squirrels.Which of the following best explains the behavior of the guard squirrels?* The behavior of the guard squirrels increases the survival of close relatives that share the genes of the guard squirrels. Option Guard squirrels typically have recessive alleles, and by sacrificing themselves, they lessen the chance that recessive alleles will get passed on. The guard squirrels confuse the predator, lowerinhe predator's success rate because the predator cannot tell which squirrel…arrow_forwardQuèstion 36 Which behavior is optimal for an organism using risk-sensitive foraging? decreased time feeding when the number of predators increases increased time spent searching for food at longer distances decreased feeding as the number of predators decreases feeding from a central supply of food or waterarrow_forwardBased on the data given in picture, Compare the number of dominant behaviors of Focal Males(crayfish) towards Intruder Males(crayfish) vs number of dominant behaviors of Octopamine Injected Focal Males(crayfish) towards Intruder Males(crayfish).arrow_forward
