Chrysemys picta belli, growth rate, bottom type
Several populations of western painted turtles (Chrysemys picta belli) were sampled during 1970 to determine the possible relationship between turtle growth rate and type of pond substrate. The populations sampled were selected because they existed in lentic habitats that had either highly organic, mud substrates or relatively inorganic, sand substrates. Age determinations based on plastral annuli showed turtles from highly organic substrates to grow more rapidly than those from substrates with less apparent organic matter. Females attained greater size than males in both habitat extremes.
