Lab 11: Animal Behav
| Question | Answer |
|---|---|
| What other stimuli might affect the behavior of pillbugs? | Light, temperature, and physical barriers |
| What is adaptive significance of a kinesis? | Because organisms will move/remain in the areas that they are able to survive and reproduce successfully |
| What is the simplest stimulus that initiates response for beta fish? | Same color |
| What factor is more important for triggering agnostic behavior for beta fish? | Bigger fish/big fins |
| Will another species of fish trigger the behavior? | Yes |
| After repeated identical stimuli, does a fish become "conditioned"? That is, does the duration of the behavior change or stop? | Yes, the duration of behavior stops |
| What is the differences between the aggressive and nonaggressive postures? | Aggressive postures are displaying of fins, flaring gills, darkening color, biting, and nipping. nonaggressive postures are swimming away or hiding |
| Will a female Betta trigger agnostic behavior in a male? If so, how does the response compare with that elicited by a male? | Yes. The response to a female would be shorter and not as aggressive compared to males |
| What is the adaptive significance of agnostic behavior? | Agnostic behavior helps assert dominance which they use to protect territory and get mates which increases reproduction and survival |
| How might the responses to the stimuli listed be adaptive: light, food, acids | Responses to stimuli such as light help with survival like finding food and staying away from predators. |
| Killdeer are ground-nesting birds common throughout North America. When a predator approaches, they often feign broken wings. What is the selective advantage of this type of innate behavior? | The selective advantage of feigning broken wings is to scare predators |
| Mating (reproductive behavior) often involves a complex sequence of events that helps an animal find, court, and mate with a member of the same species. What are some examples of these behaviors? | Ex: Elaborate displays such as male peacocks showing their bright and beautiful tails. Courtship rituals such as singing and dancing from male birds to impress female birds |
| What are the adaptive advantages of agonistic behaviors not followed by damaging fights? | Securing resources, establishing dominance hierarchies, and minimize injury risk. |
| What animals have strong displays not followed by damaging fights? | Ex: fish displaying large fin and lateral flattening to appear bigger, Gorilla eating chest and make loud noise to assert dominance |
| Do humans exhibit mating behaviors? If so, what are they | Yes. Dating like socializing to see if they are compatible with each other, gift giving, which could be a sign for resources and commitment and non-verbal cues such as eye contact, smiling, and body language |
| What animals do engage in damaging fights? | Ex: Some species of insects and snakes engage in physical fights which results in injury or death. This often happens due to limited resources and mates |
| How could taxis behavior have arisen in natural selection? | Allows individuals with genetic predisposition to move towards resources and away from danger which increases the individual fitness |
| Are behaviors inherited or are they learned? | Both |
| How could each kinesis behavior have arisen in natural selection? | Helps individuals locate favorable environments and avoiding harmful ones which benefits the individuals fitness |
| How could each agonistic behavior have arisen in natural selection? | Efficiently establishes dominance and access to resources and away from danger which increases the individuals fitness |
| Why is it important to study all aspects of animal behavior? | Because we are able to understand how to save endangered species, asses environmental quality, design nature preserves , and evaluates the importance of human-related threats to survival otherwise fit animals |
| How could the three behaviors studied (taxis, agnostic, and kinesis) have arisen from natural selection | Because the individuals that display these behaviors have greater chance of surviving and reproducing |
