survival. However, individuals may experience differential outcomes for the same set of
rates. Such individual stochasticity generates variance around familiar mean measures of
life history traits, such as life expectancy and the reproductive number R0. By writing life
cycles as Markov chains, we calculate variance and other indices of variability for longevity,
lifetime reproductive output (LRO), age at offspring production, and age at maturity for 83
animal and 332 plant populations from the COMADRE and COMPADRE matrix databases. We
find that the magnitude within and variability between populations in variance indices in
LRO, especially, are surprisingly high. We furthermore use principal components analysis to
assess how the inclusion of variance indices of different demographic outcomes affects life
history constraints. We find that these indices, to a similar or greater degree than the mean,
explain the variation in life history strategies among plants and animals. %J PLoS One %O PLoS One %V 17 %] e0273407 %I Public Library of Science %C San Francisco, CA %@ 1932-6203
