  • Abstract Only about a dozen species of animals are known to achieve maximum ages (Amax) exceeding 100 yrs, including the freshwater pearl shell (Margaritifera margaritifera). This species has a life-span of between 100–200 years depending on latitude and environmental conditions. The difference in Amax is 3–7 times when southern populations, with Amax of 28–40 yrs, are compared to northern Arctic populations, with Amax of 114–190 yrs. Evolutionary and ecological explanations for longevity in… CONTINUE READING
