Mortality curves
Mortality curves can be calculated from life tables.
For the two lakes, this is what they look like, for our study time of 5 years:
Figure 1 - Mortality at the wild lake for the first four years after human arrival
Figure 2 - Mortality at the impacted lake for the first four years after human arrival
Note: Since mortality rates are calculated between one year and the previous, mortality data for four years represent 5 years of study.
