1. What is ocean acidification and what is the primary cause?

2. Give an example of a trophic cascade from the Jellison et al. (2016) paper, and describes the effect of this particular cascade.

3. What is a ‘consumptive' pathway (also referred to in the literature as a consumptive effect)? Give an example from the paper.

4. What is a ‘non-consumptive' pathway (otherwise referred to in the literature as a non-consumptive effect)? Give an example from the paper.

5. In the paper, Jellison et al. (2016) state that they will "quantify the full behavioural ‘response function' of T. funebralis". What do the authors mean by the ‘response function'?

6. Figure 2 shows a conceptual model of what the authors predict will happen in their experimental treatments. In your own words, explain what is happening in figure 2c and 2f, and how the proportion of time spent out of water relates to a change in prey behavior.

7. Describe what is being tested in figures 4c and 4f. Were the authors correct when comparing these results with their conceptual model?

8. Given the findings from Jellison et al. (2016), how do you think decreasing pH might affect the black turban snail populations in the future? Do you think other prey species could also be affected by changes in pH too?

9. What did the authors suggest could be the root cause of how the decreases in pH are affecting the black turban snails?

10. Write out the citation for the journal article of Jellison et al. (2016) using Journal of Ecology formatting.
