Likelihood profiles for exponential growth model parameters, corrected for winter severity and winter duration. aMyotis myotis. bRhinolophus hipposideros. Thick blue line = parameter maximum likelihood estimate, thin blue lines = 95% confidence intervals of parameter estimates, dashed line = log-likelihood delimiting 95% confidence intervals of parameter estimates, a = initial population size, b = exponential growth parameter, aw and bw = intercept and slope of influence of winter severity on growth model residuals
