“…Our results support recent reports of high levels of threat in freshwater habitats (e.g., freshwater crabs; Cumberlidge et al, 2009). In particular, freshwater turtles were highly threatened (46-57%), thus mirroring the alarming trends reported elsewhere (Buhlmann et al, 2009).…”

“…Distribution of Graptemys flavimaculata in Mississippi, USA. Red dots = museum and literature occurrence records of native populations based on Iverson (1992), plus more recent and authors' data; green shading = projected distribution based on GIS-defined hydrologic unit compartments (HUCs) constructed around verified localities and then adding HUCs that connect known point localities in the same watershed or physiographic region, and similar habitats and elevations as verified HUCs (Buhlmann et al 2009), and adjusted based on authors' data. The Escatawpa River is the furthest southeastern marked locality.…”

SummaRy. -The Yellow-blotched Sawback, Graptemys flavimaculata (Family Emydidae), is a small to medium-sized riverine species endemic to the Pascagoula River drainage of southeast Mississippi, USA. Sexual dimorphism is pronounced, with adult females attaining more than twice the length and ten times the mass of adult males. Although the species is locally abundant, populations are threatened by habitat destruction, collection for the pet trade, invasive species, water quality degradataion, and other human impacts. Previously listed as Endangered on the IUCN Red List, the species has recently been downlisted to Vulnerable due to improved population estimates, newly discovered localities, and improved water qualities leading to some recovered populations. It remains Threatened because of its small range, large number of potential threats, and moderately severe declines in the largest population.diStRibution. -USA. Restricted to the Pascagoula River drainage of southeastern Mississippi.

“…The plastron is small relative to the carapace (plastral forelobe posterior width is less than 40%, and plastral hindlobe anterior width is less than 35% of maximum carapace length). The plastron has a posterior, medial notch and two distinct transverse hinges that border the central fixed portion of the plastron Iverson (1992), plus more recent and authors' data; brown dots = possible occurrence records; green shading = projected native distribution based on GIS-defined hydrologic unit compartments (HUCs) constructed around verified localities and then adding HUCs that connect known point localities in the same watershed or physiographic region, and similar habitats and elevations as verified HUCs (Buhlmann et al 2009), and adjusted based on authors' data. the adult appear in Schmidt (1947), Medem (1961Medem ( , 1962, Legler (1965), Pritchard (1979), Iverson (1981), Ernst and Barbour (1989) Distribution.…”
