Figure 3. Nonlinear polynomial regression relationship between substrate hardness and die-off.

Figure 3

Substrate hardness explained 46% of inter-site variation in die-off. Intermediate substrate hardness experiences the highest level of die-off. Soft substrate cannot support burrows while hard substrate is too hard to burrow in.
