Yamane Gilman (2009)

Effects of Body Temperature on Predation Rates.

Background: The author talked about the predation rates of Nucella ostrina which happened to vary between treatments.  There is not really a clear reflection of just the procedure based of the results.
Question: The question is clear; the author is asking whether or not body temperature has an effect on predation rates among Nucella ostrina.

Method: They conducted the experiments with different exposure rates. One set was exposed to a higher submerged temperature where as the other set were exposed to a different submerged temperature.

Observation: They discovered that Dogwhelks which were exposed to a higher temperature had consumed 75% fewer barnacles. They also had less tissue mass then the others which were exposed to different temperatures. There was no difference in the consumption rates of the other two tanks. The exposed tank had a higher rate than the controlled group.

Conclusion: The conclusion is that the higher the body temperature the higher the consumption of barnacles become. Reading through there seems to be a difference between aquatic water tempura and aerial temperature in effects of functions.

These answers did take a little bit of time to just think about before they could be answered. I definitely had to read through the results section a couple of times to really grasp the idea.
