In the initial encounter with the male intruder, resident male Cray fish showed extreme aggressive behaviors towards the intruder but after getting injected with octopamine, the resident male showed less aggression towards intruder males compared to their initial encounter. Based on what you know about serotonin an octopamine function, does the above situation of the injection octopamine makes sense? What might explain this and why do you say so? Also, what fitness benefits might a crayfish that shows dominance behaviors and a crayfish that shows subordinate behaviors gain?

Using the attached table that shows the total score for submissive and dominant behaviors of the territorial male during each. Larger number shows more aggression in the resident individual. Low Aggressive behaviors (worth 1), medium aggressive behaviors (worth 2) and the most aggressive behaviors(worth 3). Based on the table:Did octopamine injected male residencts(crayfish) seem to be more or less aggressive by displaying dominance behaviors towards intruder males compared to their initial encounter with a male intruder based on theT test results?
Using the attached table that shows the total score for submissive and dominant behaviors of the territorial male during each. Larger number shows more aggression in the resident individual. Low Aggressive behaviors (worth 1), medium aggressive behaviors (worth 2) and the most aggressive behaviors(worth 3). Based on the table:Did non-injected male resident seem to be more or less aggressive by displaying dominance behaviors towards intruder females compared to intruder males. Answer this based on the T test results? Is there an any explanation for these observations? Use only dominant scores from focal males A to H for a total of eight pairs of data from treatment 1 and treatment 2?
Based 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).
Describe and give an example of a dominance hierarchy. What role does it play in social behavior? Give a human parallel, and describe its role in human society. Are the two roles similar? Why or why not? Repeat this exercise for territorial behavior in humans and in another animal.
You were given two examples of learning in class. One related to wasps using landmarks to find nesting sites. The other related to mate choice in birds where the females were exposed to potential mates with artificial crests on their heads. What is the difference in the learning between the two studies? Group of answer choices the wasp study looked at the relatedness among individuals doing the learning both studies demonstrated that the behavior was purely genetic with no learning involved the bird study studied learning and development, permanent changes in behavior as a result of juvenile experience the wasp study studied learning and development, permanent changes in behavior as a result of juvenile experience
Northern flickers are woodpeckers of the eastern United States. Males, but not females, have black feathers that resemble a moustache extending from the bill along each side of the head. Aggression between males is common, but male and female members of breeding pairs are not aggressive toward one another. However, when scientists painted a moustache on female members of breeding pairs, their mates attacked them. This suggests that a.) the moustache is a releaser for aggression. b.) aggression is a learned behavior. c.) the moustache is a neutral stimulus. d.) aggression is a conditioned reflex. e.) the moustache is a conditioned stimulus.
Animals 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)
The idea that behavior must be either innate or learned has been called a “nature versus nurture” controversy. What reasons are there for believing that such a strict dichotomy does not exist?
Which of the following questions is most closely associated with anultimate cause of a behavior?a. How does a squid alter its color to blend in with its environment?b. How does a hummingbird’s body shape influence its ability tohover?c. How do alarm calls affect prairie dog fitness?d. Which cues do monarch butterflies use during migration?
Write a essay in the form of an introduction to the research area of the topic 'Neuroscience of social behaviour'. write an overview of 4 research articles explaining the contribution of these articles to research in the topic area. the 4 research articles are: orebrain control of behaviorally-driven social orienting in zebrafish by Sarah J. Stednitz perceptual mechanisms of social affiliation in zebrafish by Ana Rita nunes1 Genetic variation in the social environment affects behavioral phenotypes of oxytocin receptor mutants in zebrafish by Diogo Ribeiro1 Biological Motion as an Innate Perceptual Mechanism Driving Social Affiliation by Johannes Larsch
Fish produce a hormone called isotocin, a hormone that is similar to oxytocin in mammals. Both hormones, oxytocin and isotocin, have been linked to social behaviors including the suppression of social anxiety, trust, and attachment. Prior to this study, the relationship between isotocin in the bloodstream and the amount of aggression or submission individual cichlid fish display was unknown. The researchers hypothesized that isotocin would suppress aggressive behaviors in cichlids to promote social cohesion as these fish exist in large social groups (schools). To address this hypothesis, each of 10 fish were exposed to two treatments, 1 week apart. One at a time, a fish was randomly selected from the group of 10 and either injected with a saline solution (that served as the control) or with isotocin. After this injection, the fish was returned to its group and the amount of aggressive and submissive behaviors the fish demonstrated was recorded for the next 10 minutes. One week later…
