Maximum Life Span

Our study generated a linear mixed effects model which revealed that there is a negative correlation between the number of number of offspring produced in a year and the lifespan of the mother (Figure 3). Using orders as the random effect, the linear mixed effects model was a better fit for the data with a lower AIC rank of 714.4 in comparison to the generalized linear model which had a AIC rank of 837.0 (Table 1). Though this negative correlation is seen for all 7 mammalian orders, the correlation for some orders were stronger since the magnitude of their slopes were more negative, such Carnivora (-1.2317), Primates (-1.01260), and Artiodactyla (-0.6997) (Table 1). Whereas for others the magnitude of their slopes were less negative such as, Cetacea (-0.4379), Insectivora (-0.4388), Lagomorpha (-0.4610), and Rodentia (-0.4696) (Table 1) with the biggest difference between the most negative slope, Carnivora and the least negative slope, Cetacea is about 0.7937294.
