The Nonindigenous Occurrences section of the NAS species profiles has a new structure. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Occurrences are summarized in Table 1, alphabetically by state, with years of earliest and most recent observations, and the tally and names of drainages where the species was observed. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables.

Ecology: Habitat: Large slow-flowing rivers and associated backwaters and ponds (Ernst et al., 1994).

Life History: Reaches maturity at three to four years and plastron length of 12–14 cm (males) or five to seven years and 24-25 cm in length (females) (Ernst et al., 1994). Two to six clutches ranging from 10 to 29 eggs are laid. Nesting occurs any time of year in Florida, but usually not in summer. Elsewhere, nesting is in spring and approaching summer in the northern extent of its range (Ernst et al., 1994).

Means of Introduction: Probably pet release.

Status: Failed in Massachusetts (Cardoza et al., 1993) and Maryland.

Remarks: Scientific and standard English names follow Crother (2008).
