Data from: Correlative changes in life history variables in response to environmental change in a model organism

Global change alters the environment, including increases in the frequency of (un)favourable events and shifts in environmental noise colour. However, how these changes impact the dynamics of populations, and whether these can be predicted accurately has been largely unexamined. Here we combine recently developed population modelling approaches and theory in stochastic demography to explore how life history, morphology and average fitness respond to changes in the frequency of favourable environmental conditions and in the colour of environmental noise in a model organism (an acarid mite). We predict that different life history variables respond correlatively to changes in the environment, and we identify different life history variables, including lifetime reproductive success, as indicators of average fitness and life history speed across stochastic environments. Depending on the shape of adult survival rate, generation time can be used as an indicator of the response of populations to stochastic change, as in the deterministic case. This work is a useful step towards understanding population dynamics in stochastic environments, including how stochastic change may shape the evolution of life histories.
