Population persistence by temperature interval for temperature-dependent sex determination (TSD) populations. (a) Temperature-dependent embryonic survival curve (TS) (black solid line) and cohort sex ratio (CSR) (black-dashed line) with intercept and slope parameters (α = 4.14, β = -0.147), for populations of reptiles with TSD. The unlabelled left axis represents juvenile survival and the unlabelled right axis represents the proportion of male hatchlings. (b) to (h) shows distributions of surviving populations of reptiles with TSD by temperature (°C) for dispersal conditions. The maximum population in each temperature interval is 1000.
