Size of adult and juvenile Gambelia sila by day of year

Sometimes it can be tricky to distinguish small adult and large juvenile leopard lizards. Fortunately, the two age groups separate cleanly on axes of snout to vent length and day of year. This plot shows data from 13 years (1993 – 2005) on the Elkhorn Plain, during a variety of environmental conditions and lizard growth rates. Juveniles are lizards born this year. Adults were born in a previous year.Gsila_size_by_date
