Paternity analysis was used to examine the reproductive success of 54 male Blanding's turtles captured on the University of Michigan's E. S. George Reserve (ESGR), Livingston County, Michigan, USA. Multi-locus microsatellite genotypes were used to assign paternity to 266 hatchlings from the ESGR using the likelihood approach employed by the program CERVUS 2.0. Likelihood analysis could not establish paternity for all hatchlings, but the paucity appeared related to non-resident females nesting within the ESGR not to the efficacy of the markers employed. Several statistical approaches were used to examine the relationship of male success to ESGR residency, residence area (area a male was captured most frequently within the ESGR), residual body mass, body size and age. Male success was not related to ESGR residency, residence area, or residual body mass, but was significantly correlated with male size and age. When both size and age were considered in a multivariate analysis, only age remained significantly correlated with male success. Similarities to the closely related wood turtle (Clemmys inscuplta) suggest male Blanding's turtles may employ a mate-searching strategy that improves with age (e.g., navigation, experience mating). Further study is required to test this hypothesis.
