Sample sizes are shown for the initial cohorts at about 30 and 90 days of age. The ordinate indicates the natural log (In) of the number of survivors with N=1,000 at t=0. Table 1. Survivorship of adult (a 40 mm svl) and juvenile (< 40 mm svl) anolis limifrons on Lutz and AVA SITES. Daily survivorship has been converted to survivorship over a 28 day period (S^*). The total number of individuals counted in the initial census follows survivorship in parentheses. Survivorship was determined only when the initial number of individuals was 20 or more. Mean juvenile snout-vent length (SVL) shown is for the initial census. Census Intervals Lutz site Survivorship Juvenile (days) Adult!
