Chapter 51, Problem 7TYU
Level 3: Synthesis/Evaluation
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.

Students have asked these similar questions
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?

Part 1. Neuroscience of social behaviour
The data in figure 1 below show the shoaling behaviour of wild-type zebrafish compared to
a novel zebrafish mutant. Groups of sixteen fish were placed into a large rectangular tank
and their behaviour was recorded for 5 minutes. Tracking software was used to estimate
the nearest neighbour distance and inter-individual distance. The bar charts depict the
mean and standard deviation (shown as an error bar). ** indicates a statistically significant difference
individual differences.
Q1. Describe the phenotype of the mutant zebrafish compared to wild-type.

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).

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.
