Divergence of discrete- versus continuous-time calculations of the temperature dependence of maximum population growth rate.

ABSTRACT: The temperature dependence of population fitness (rm) is key to predicting ectotherm responses to climatic change. Discrete-time matrix projection models (MPMs) are used to calculate rm because they capture variation in its underlying life-history trait values and time delays inherent in those traits. However, MPM calculations can be laborious and do not capture time's continuous nature. More complex approaches for calculating temperature-dependent rm may be more accurate but they are notoriously difficult to parameterise. Ordinary differential equation-based models (ODEMs) offer a relatively tractable alternative of intermediate complexity, but it is unknown whether they broadly agree with MPM calculations when environmental variation is introduced. Here we investigate differences in the
