Global Range: (5000-20,000 square km (about 2000-8000 square miles)) Peninsular Florida, north along the Atlantic coast to the St. John's River and northwest in the Suwannee River system; occurrence in the panhandle of Florida is uncertain (Seidel and Ernst 1998).

Range Description

Pseudemys peninsularis occurs through most of peninsular Florida; the precise northern limits of occurrence are unclear given the historically complicated taxonomy and identification of individuals and the wide zone of apparent intergradation with floridana from Ocala to Tallahassee (Thomas and Jansen 2006, Ernst and Lovich 2009).

Habitat and Ecology

Habitat and Ecology

Pseudemys peninsularis inhabits nearly any freshwater body within its range that provides soft sandy bottom, abundant basking sites and extensive submerged vegetation, occurring in streams, rivers, canals, lakes, springs and ponds. It occasionally enters brackish water (Ernst and Lovich 2009)

Pseudemys peninsularis is apparently exclusively vegetarian, feeding on a wide variety of submerged aquatic plants, as well as some floating and marginal plant species (reviews by Thomas and Jansen 2006, Ernst and Lovich 2009).

Females reach up to 40.3 cm carapace length (CL), while males do not exceed 35 cm CL. Males reach maturity at three to six years at 12–15 cm CL, while females mature at age 5–15 years and 24–30 cm CL. Mature females produce at least two, possibly up to six, clutches of on average 15 (range 6–29) eggs annually. Hatchlings measure 19–36 mm CL and 7–10 g (Thomas and Jansen 2006, Ernst and Lovich 2009). Longevity and generation time have not been documented.

Migration

Non-Migrant: No. All populations of this species make significant seasonal migrations.

Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Justification
Pseudemys peninsularis is widespread in peninsular Florida and generally common in suitable habitat including a variety of protected areas. Localized indications of decline have not combined into an overall pattern of persistent decline, and while monitoring of population trends is warranted, the species does not appear to approach qualifying for the threatened categories. It is therefore assessed as Least Concern.

Population

Population

Within its limited range, P. peninsularis is generally abundant where it occurs. Densities of 44-48 individuals per hectare have been reported for different rivers (Kramer 1995, Giovanetto 1992, in Thomas and Jansen 2006). Densities and proportional abundance compared to syntopic P. concinna suwanniensis and P. nelsoni changed over time in Rainbow Run since the first study in 1942, with the species retaining similar proportions within the Pseudemys numbers, but becoming proportionally less common overall (which may reflect increased aboundance of Sternotherus minor) (Huestis and Meylan 2004).

Threats

Major Threats

Threats reported for Pseudemys peninsularis include habitat destruction and pollution; alteration of aquatic vegetation abundance and structure by intensive grazing by introduced Asian Carp (Ctenopharyngodon idella) as well as direct competition for the aquatic plant resource; degradation of water-edge habitat, including loss of optimal nesting sites; collection of animals for consumption by humans and as pets; direct mortality from boat propeller strikes and road mortality when crossing roads; and wanton mortality from shooting, and killing by fishermen as perceived competitors (reviews by Thomas and Jansen 2006, Ernst and Lovich 2009).

Management

Conservation Actions

Conservation Actions

Pseudemys peninsularis is protected from commercial exploitation in Florida, and substantial populations occur in several protected areas. Safeguarding ecosystem integrity in the face of invasive species and human habitat alteration appear primary requirements, while continuing the current long-term population monitoring program at Rainbow Run and expanding turtle monitoring to other locations would be welcome. Extensive recommendations for conservation were provided by Thomas and Jansen (2006).

Wikipedia

Peninsula cooter

The peninsula cooter (Pseudemys peninsularis) is a species of freshwater turtle in the genus Pseudemys. It is sometimes considered a subspecies of the coastal plain cooter (P. floridana) when that turtle is not itself considered a subspecies of the river cooter (P. concinna).

Distribution[edit]

The species is found in the Florida peninsula.[2]

Names and Taxonomy

Taxonomy

Comments: The taxonomic status of Pseudemys peninsularis is controversial. This taxon was recognized as a distinct species by Seidel (1994, 1995), Seidel and Ernst (1998), and Crother et al. (2000, 2003). Jackson (1995) reasoned that peninsularis should be retained as a subspecies of P. floridana. Crother et al. (2000, 2003) treated floridana as a subspecies of P. concinna whereas Jackson rejected this change.
