WebOct 22, 2015 · The package allows the integration of four types of covariates that may affect both survival and capture rates: covariates varying between individuals (such as sex), in time (such as climatic or vegetation measures), both time-varying individual covariates (such as body mass) and age as a categorical covariate. WebEstimation of avian nest survival has traditionally involved simple measures of apparent nest survival or Mayfield constant-nest-survival models. However, these methods do not allow researchers to build models that rigorously assess the importance of a wide range of biological factors that affect nest survival.

WebTo do this effectively, more advanced tools than Mayfield's ad hoc estimator are needed.

There is a positive correlation between young forest survival and SOI (Adj R 2 = 0.65, p = 0.002); conversely, no correlation was detected between mature forest survival and SOI (Adj R 2 = 0.01, p = 0.35).
