  1. Covariates are grouped according to their effect on population growth rates, home range activity centres, density, and detection processes. Covariates are then grouped by their respective source of data. Behaviour refers to covariates for a behavioural response at baited SCR sites, thin refers to probability of identifying an individual at SCR sites with marked and unmarked individuals. number days refers to the number of sampling days. Estimates given are the median, standard deviation (SD), and lower (lcl) and upper (ucl) 95% Bayesian confidence levels.
