Parameter Description Effect type
Population ID Unique ID from the LPD representing a single population. accounting for population-specific effects. Random intercept
Species name Units Data type Species binomial accounting for species-specific effects. The units of population abundance e.g. number of individuals, number of breeding pairs etc., accounting for effects of unit of measurement. Type of data used to monitor the population e.g. full population count, sample, proxy etc., accounting for the effects of study design. Random intercept Random intercept Random intercept
Population size Raw population abundance measurement taken from the LPD. Fixed
Log10 Population size Log-transformed (base 10) population abundance measurement. Fixed
Body mass (BM) Log-transformed (base 10) body mass (kg) of species. Fixed
Years to extinction Rescaled time variable, counting backwards from extirpation Fixed
