“…Eastern Box Turtles, partly by virtue of their longevity, may concentrate toxic chemicals and isotopes in their tissues (Jackson et al 1974;Holcomb and Parker 1979;Beresford et al 1981). The effect, if any, on the behavior and population dynamics of Eastern Box Turtles of these chemicals is unknown, though environmental contaminants (particularly organochlorines) have been suggested as a potential cause for illness (Tangredi and Evans 1997) and abscesses in turtles due to its interference with metabolism of vitamin A (Holladay et al 2001;Brown et al 2003), but results are mixed (Sleeman et al 2008).…”

The Eastern Box Turtle, Terrapene carolina (Family Emydidae), as currently understood, contains six living subspecies of small turtles (carapace lengths to ca. 115-235 mm) able to close their hinged plastrons into a tightly closed box. Although the nominate subspecies is among the most widely distributed and well-known of the world's turtles, the two Mexican subspecies are poorly known. This primarily terrestrial, though occasionally semi-terrestrial, species ranges throughout the eastern and southern United States and disjunctly in Mexico. It was generally recognized as common in the USA throughout the 20th century, but is now threatened by continuing habitat conversion, road mortality, and collection for the pet trade, and notable population declines have been documented throughout its range. In the United States, this turtle is a paradigm example of the conservation threats that beset and impact a historically common North American species. In Mexico, the greatest need for the subspecies that occur there is to further assess their distribution, habitat requirements, economic status, and conservation threats. distRibution.-Canada (extirpated), Mexico, USA. Broadly distributed in eastern and southern USA from southern Maine and New Hampshire to Florida and west to Michigan,

“…The utilization of fat reserves results in the redistribution of the pesticide and or its metabolites. These compounds are eventually eliminated into the urine and feces (Matsumura 1975) or are transferred to eggs in utero (Flickinger and King 1972, Holcomb and Parker 1979, Punzo et al 1979, Stone et al 1980. Liver and kidney in turtles tend to contain concentrations of these pesticides that are lower than that detected in fat, but higher than that detected in other soft tissues (Meeks 1968, Pearson et al 1973.…”

Erythrocyte sedimentation rate and hemoglobin-binding protein in free-living box turtles (Terrapene spp.)

The acute phase response is a highly conserved reaction to infection, inflammation, trauma, stress, and neoplasia. Acute phase assays are useful for wildlife health assessment, however, they are infrequently utilized in reptiles. This study evaluated erythrocyte sedimentation rate (ESR) in eastern (Terrapene carolina carolina) and ornate box turtles (Terrapene ornata ornata) and hemoglobin-binding protein (HBP) in T. ornata. Erythrocyte sedimentation rate in 90 T. carolina and 105 T. ornata was negatively associated with packed cell volume and was greater in unhealthy turtles (p < 0.05). Female T. ornata had higher ESR values than males (p < 0.05). Measurement of ESR with a microhematocrit tube proportionally overestimated values from a commercial kit (Winpette), though both methods may retain utility with separate reference intervals. Hemoglobin-binding protein concentration in 184 T. ornata was significantly increased in adults and unhealthy turtles (p < 0.05). Erythrocyte sedimentation rate values were similar between seasons and populations, and HBP values were consistent between years, indicating that these analytes may have more stable baseline values than traditional health metrics in reptiles. This study demonstrates that ESR and HBP are promising diagnostics for health assessment in wild box turtles. Incorporating these tests into wild herptile health assessment protocols may support conservation efforts and improve ecosystem health monitoring.
