Biology 124 Lab Case Study "No Bats in the Belfry: The origin of White-Nose Syndrome in Little Brown Bats" Part 1 Questions 1. What is the basic question of the study and why is it interesting? The basic question of thIs study is "Is the European strand of Pseudogymnoascus destructans causing White-noise syndrome (WNS) in the United States?" This question is interesting because if it is the European strand of P. destructans causing WNS in North America then why is it not occurring in as high of levels and why are bats not dying in as big of a capacity in Europe as the bats in North America. 2. What specific testable hypotheses can you develop to explain the observations and answer the basic question of this study? Write at…show more content…
2. Describe an experiment you could use to differentiate between the null and alternative hypotheses. An experiment could be devised in which bats are taken in a large quantity and one group in injected with the North American P. destructans strand, a second group is injected with the European P. destructans strand and a third group is injected with a placebo. The bats should be placed in a cave like setting and the effects of the injections should be examined. Part 3 Questions 1. Use the graph below to predict what the results will look like if the null hypothesis is supported. The total arousal counts in the control treatment at each interval is graphed for you. Justify your predictions. 2. Use the graph below to predict what the results will look like if the null hypothesis is rejected. The total arousal counts in the control treatment at each interval is graphed for you. Justify your predictions. Part 4 Questions Study Results 1. How do your predictions compare with the experimental results? Be specific. My predictions for the acceptance of the null hypothesis were very similar to the actual results with a few variations. My prediction of total arousal times for the first interval were the same however, on the second interval I had 60 total arousal times for the bats injected with the European P. destructans strand and the actual results had a total arousal of 80 bats injected with the European strand at interval
