Abstract

The purpose of this study was to estimate the variation in growth and survival that occur during the larval stage of Dicamptodon tenebrosus. We used mark-recapture to assess the rates of apparent survival and growth for two larval age classes (first-years and second/third-years), in winter and summer seasons and in the presence of culverts. By estimating the capture probability of larval D. tenebrosus, we also attempted to provide more accurate estimates of survival than simple recapture rates.
