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.

- 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. dP rN - aNP= = faNP - qP dt dt Type 1 functional response with density-dependent prey and density- independent predator Type 1 functional response with density-independent prey and density- independent predator Type 1 functional response with density-dependent prey and density-dependent predator Type 1 functional response with density-independent prey and density- dependent predatorarrow_forwardNote a particular animal behaviour at the Central Experimental Farm in Ottawa, (eg. chickens, cows, horses, sheep) on at least four (4) different occasions, taking note of the animal’s targeting (observed) behaviour, as well as any other competing or associated behaviours that may have an impact on that animal’s decision-making processes while under your observation. Your total observation time over the 4 periods must add up to at least 2 hours of data. Keep a log of these observations and also do a 1-page report attempting to describe the adaptive value of the behaviour that you observed. For clarification, the adaptive value is a measure of the evolutionary impacts of a behaviour, i.e. the ultimate function of a behaviour (what purpose it serves) in order to maximize fitness (survival and/or reproduction).

- What is the summary of this paragraph?arrow_forwardMuch 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_forwardBayesian 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_forward
- Need 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_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_forward12arrow_forward
- 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_forwardThe acquisition of memories can be demonstrated in rodents on a T-maze task.

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_forward
