Title Animal Behavior Lab Report Introduction Social behavior is defined as interactions among individuals, normally within the same species, they are e usually beneficial to one or more of the individuals. Social behavior is not only displayed by animals possessing well-developed brains and nervous systems. Social behavior consists of a set of interactions among individuals of the same species. And of course social behavior can include one-sided displays of aggression, or assertions of dominance. Examples of human social behavior include, shaking hands.Research Question Will females sow bugs be aggregated by a single male if placed in a container. Method We gathered sow bug in a container and separated the male from the female.
After we found 5 different females, we placed them in a dish. We then placed the male in the opposite side of the dish. We then took out a stopwatch and began to observe the behavior of the sow bugs. We done this for 3 minutes and recorded the behaviors we saw after each minute, after the 3 minutes, we change the sow bugs and put In 5 new females and 1 new male and went through the same process.
We done this process a total of three times. Hypothesis If a group of 5 female sow bugs are placed in a container with 1 one male, then female sow bugs are more likely to cluster in groups together. Claim Because female sow bugs are aggerated by male sow bugs than female sow bugs avoid the male sow bugs rather than crowding and grouping together ResultsFirst trial Min 1: male gets in top of female pill bug. Other females start moving. One moves completely away.
Some stay still. Min 2: Male stayed on top of female. Other females try to get awayMin 3: Female tries to get away from the male that is trying to mate. Other female attempts to interfere. Male eventually breaks away and the females runs away to the other females. Second Trial Min 1: females did not move. Male is circling Min 2 Females are crowding.
Male may be intimidated and is trying to get away.Min 3: Male appears interested and is going towards the females. Females are trying to stay with each other.
Third TrialMin 1: females are moving around male has his antennas searching.Min 2: Females are still trying to get away. Male still searching.
Min 3: Females still avoiding male still searching. We noticed that the female sow bug didn’t crowed as much as we thought they would, and the male took a bit more time to go search for the female sow bugs, we noticed that in our third trial the females bugs in particular started to run away from the male sow bug. The male was searching hard for the female, but they would just run away if approached by the male. I think this was the case because we had the same females and males in the container for the second and third trial so I figured that they knew what was going on and were more alert. Justification The close presents of males promote the entrance of female into a reproductive state. This support our claim Because females do aggregate however it does not because they rarely crowded together. The female reproduction can be affected by the presence of other females.
This supports our claim Because females do aggregate however it does not because they rarely crowded together. The evidence supports our claim because the female do aggregate, however it does not because they rarely crowded together. The close present of males promote the entrance of female into a reproductive state.
Females reproduction can be affected by the present of other femalesWe identified that female sow bugs run away rather than crowding together. Maybe try different females in the experiment and see if the male interacted with the females. We could have used More variation of females instead of using the same ones in each trial.
Because with more variation, we would’ve had more accurate data We only use two sets of 5 females, so there was some variation. Focus on the male and see if the male would interact with the females. This could have Gaining us more information. We did look at the male and the male interacted with the fatter females within the petri dish- we were focusing on our females in the study, not so much the males- separate experiment Science influences society through its knowledge and world view. Scientific knowledge and the procedures used by scientists influence the way many individuals in society think about themselves, others, and the environment.
The effect of science on society is neither entirely beneficial nor entirely detrimental.Resources Broly, P., Deneubourg, J., & Devigne, C.
