Only data from the 2010 to 2011 survey was used (189 unique individuals). The mite abundance is categorized into four levels (zero mite, 1 to 9 mites, 10 to 19 mites, and 20 mites or more). Mean mite abundance is used for repeatedly captured individuals. The logit link function is applied. The primary CJS model is φ(sex)p(.), which has sex-specific survival functions (φ_female = int_female + β_female × mite abundance, φ_male = int_male + β_male × mite abundance) and a recapture probability function (p = int_p + β_p × mite abundance). A reduced CJS model, φ(.)p(.), has the constraints that β_female = β_male and int_female = int_male. The parameter estimates of the survival and recapture probability functions are expressed as the means followed by their 95% confidence limits in parentheses.
