BIO182 Activity 7 Worksheet Spring
1. In general, how does the breadth of the thermal niche (CTmax minus CTmin) change with
latitude? (Calculate the difference between CTmax and CTmin and graph it against
absolute Latitude. For these graphs, it is easiest to put Latitude on the X axis.)
As latitude increases, CTmin and CTmax grow farther apart.
2. Is the change in the breadth of the thermal niche (CTmax minus CTmin) the same in
aquatic and terrestrial animals? (Sort the data by terrestrial and aquatic and
compare graphs of CTmax-CTmin vs absolute Latitude).
No, terrestrial animals have a larger change in thermal tolerance; it
increases steadily while aquatic animals slightly decrease.
3. Which changes more with Latitude in terrestrial animals, CTmin or CTMax? (Keep the
columns sorted by habitat, graph each of these against absolute Latitude and make a
trend line if necessary to see which has the greater slope).
