- 1. What are the 4 examples of social behaviour among species according to Herron and freeman (2015). Discuss one example of each types of interaction. And lastly, explain one problem related to the concept of coevolution. Give an example.5) According to the optimal foraging theory, which of the following is NOT one of the factors that influence the likelihood of a predator's selecting a prey type? Question 5 options: search time required to find alternative prey types profitability of the prey type handling time energy content probability of their own predation1. Base on the graph below, why might the sex ratio of bird species in the figure change from as they grow from juveniles to adults? 0.5 0.5 40 50 30 40 30 20 20 10 10 0.30 0.36 0.42 0.48 0.54 0.60 Sex ratio 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0 Sex ratio (b) A) Nesting females are vulnerable to predatory attack. B) Males that are unable to mate die quickly. C) Females are less able to feed effectively as juveniles. D) More females are required to sustain the population. Frequency (a) Frequency I
- 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 wk1.In wildlife management, population numbers must be sustainable in that populations cannot exceed the environment’s ability to support them. Using the ∆N formula, consider the following: Coyotes are members of the Canis family, or dog family, that wanders natural or agricultural grasslands and temperate forest in search of rodents and small prey. Occasionally they will form packs to bring down a larger animal – perhaps a young, sick, or old deer. In this scenario, assume population numbers of coyotes have increased dramatically. a.Using your knowledge of the ∆N formula, provide four possible causes for this dramatic increase in population. b.Assume you are a wildlife manager and that the high coyote population is resulting in more human/coyote interactions. Steps need to be taken to correct the imbalance in coyotes. Provide two ecologically sound solutions to the problem.1. Describe two types of interactions between two competing species. 2. Explain how potentially competing species may co-exist. 3. Explain resource partitioning. Give an example. 4. Discuss the co-evolution of predator defences. 5. What is mutualism? Discuss in the context of coevolution. 6. Explain optimal foraging 7. Explain the Red Queen view of evolution 8. Explain one problem related to the concept of coevolution. Give an example. 9. What are the 4 examples of social behaviour among species according to Herron and freeman (2015). Discuss one example of each type of interaction.
- 9. An undergraduate ecology student doing research on niche dimensions decided to repeat part of R. H. MacArthur's famous study of foraging behavior of warblers in northeastern coniferous forests. She marked the heights of various branches in several conifers with colored tape and observed two similar species of warbler with binoculars and recorded the average foraging height for each bird. The heights in feet for the individuals observed were: Bay-breasted warbler 17 10 13 12 13 11 13 16 17 19 Blackburnian warbler 15 17 17 18 15 16 17 24 20 16 24 15 (a) Calculate the mean and standard deviation of the foraging heights for each species. Comment on the results. (6) Determine the median and range for each species. Which of the two statistics, the standard deviation or the range, is a better reflection of the variability in the foraging height? Explain.The relationship between predator and prey populations has been studied by computer simulation using equations which form part of a mathematical model devised by Lotka and Volterra. The data in Table 6.10 show the results of such a simulation when the prey population begins with 20 individuals and the predator population begins with six individuals. 1.Explain why the peaks in the predator population occur after those in the prey population. 2. This simulation assumes one prey species and one predator species in an imaginary ecosystem and is based on mathematical equations. Why is it likely to be too simplistic to describe accurately what happens in nature?How is a clumped population distribution beneficial for prey animals? Being a member of a larger group provides protection for each individual from predators Prey animals rely on each other to acquire food Prey animals live in small family groups to raise young Clumped population distributions ensure that at least one member of the population knows how to identify the seasonal migration route.
- Interpret the following graphs: In the graphs, the number of days are 18.. 1 day is equal to 60 sec. For the first graph, days are taken on x-axis. The mean foraging times are taken on y-axis. For the 2nd graph, percentage of prey caught during first half of winter(1-6days) were taken on x-axis and percentage of prey caught during 2nd half of winter(7-12days) were taken on y-axis.12. Which of the following dynamics are not predicted by the Lotka-Volterra predator-prey model using an exponential growth function (the simplest form)? a. exponential decline of the predator population in the absence of prey b. coexistence of predator and prey c. exponential growth of the prey population in the absence of predators d. none, all of these are predicted by the predator-prey model e. unstable oscillations in predator and prey densityMuch 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 .
