Immunosenescence and its influence on reproduction in a long-lived vertebrate, the painted turtle

These data include information on male, female, and juvenile painted turtles (Chrysemys picta) captured from Thomsom Causeway Recreation Area in Thomson, Illinois, USA in 2011. These turtles are part of a long-term mark-recapture study, and as such have information on age at first capture. These known ages, combined with ages estimated from growth models created from turtles in this population, were used to assess patterns of immunosenescence in three innate immune measures: agglutination ability, lysis ability, and bactericidal competence of plasma. We additionally tested the influence of sex, day captured, and clutch size on these immune measures. Clutch size information was collected for female painted turtles for which we had excavated nests and counted the number of eggs laid.
