rds removed the food. After graphing the data, I failed to accept my null hypothesis. I thought that the diffent time periods of the day would affect when the birds would usually remove the larvae. I imagined that birds would come out first thig in the morning and then go bacl to their nest. However through the one could see that the results in both days were very similar. In addition when I calculated the chi square analysis for both periods, they were 17.7 for PM and 15.83 for Am. These numbers were both larger than the given value in the book of 3.84, which is why I failed to acceot my null hypothesis. The results of this lab were sometimes a little difficult to interpret due to various mistakes. One large and costly mistake was missing data. Several groups did not report their data, which resulted in the graphs and calculations being somwhat unusual and often difficult to understand. There were also often large gaps in the graphs. The problem of negative numbers in the data threw off the graphs even more than it already was. Also, although not proven, it is possible that othe organisms or enviromental conditions could have interfiered with the data collection. The factor of the wind must be taken into account for emoving the prey. If the prey was removed, it doesn't mean that the predators had eaten it. The predator also could it in his or her mouth and spit it right back out. This response would be very important to mimicry , because the preadator or prey is realizing what is palatable and what isn't. The negative numbers that appeared in this experiment could have been the cause of experimental error, due to the fact that there were two extra larvae in each petri dish. There were quite a few mitakes in this data but at least we successfuly obtained viable data.According to the graphs, the birds preyed upon the red larvae the most. The red larvea was 100% palatable and 0% unpalatable. I expected the red larvae to be preyed upon ...
