  CTTC - Blanding's Turtle, Emydoidea blandingii by James Harding
Adult males have a plastron that is somewhat indented in the center (concave), while the females have a flatter plastron.
Considering the long distance that often must be traversed by the young to reach suitable aquatic habitat, one might conclude that Emydoidea neonates are either extremely resistant to desiccation and temperature fluctuations, or extremely unlikely to survive their first weeks out of the nest.
Possibly the latter presumption is closer to the truth, as young Blanding's turtles are rarely encountered in the wild.

The Blanding's turtle (Emydoidea blandingii) and the Northern Leopard Frog (Rana pipiens) have been on the threatened species list of many areas within their ranges due to loss of habitat and other decimating and welfare factors directly or indirectly related to humans.
Emydoidea blandingii, or Blanding's Turtle, ranges from southwestern Quebec and southern Ontario south to southeastern Minnesota (and down to Illinois and north-central Nebraska) and west to northwestern Pennsylvania (Nova Scotia).
The largest threat to Emydoidea is man-made roads near their habitat: they cross these roads, usually between wetlands and uplands, for breeding purposes and are run over by unsuspecting drivers.

 Turtles of the World > Species: Emydoidea blandingii (Blanding's turtle)
Emydoidea lives in productive, eutrophic habitats, with clean shallow water, a soft but firm, organic bottom, and abundant aquatic vegetation.
Bramble (1974) has shown that Emydoidea is most closely related to Emys and Terrapene, rather than Deirochelys, as was previously believed.

The Blanding's Turtle (Emydoidea blandingii) is a species of semi-aquatic turtle.
It is the only species in the genus Emydoidea, and is considered to be a threatened or endangered species throughout much of its range.
The Blanding's turtle is a medium-sized turtle with an average shell length of approximately seven to nine inches and a maximum length of 10 inches.

The Blanding's Turtle is rare and locally distributed in the north-central and northeastern regions, and is listed as a threatened species in Wisconsin. Over 50% of Wisconsin wetlands have been lost, and this continuing habitat destruction negatively impacts this species, as does increasing traffic mortality, especially among nesting females.

Cold-hardiness and dehydration resistance of hatchling Blanding's turtles (Emydoidea blandingii): implications for overwintering in a terrestrial habitat
Abstract: The overwintering habits of hatchling Blanding's turtles, Emydoidea blandingii (Holbrook, 1838), are not well understood.
To ascertain whether these turtles are well suited to hibernation on land, we examined susceptibility to dehydration, supercooling capacity, resistance to inoculative freezing, capacity for freeze tolerance, and physiological responses to somatic freezing in laboratory-reared, hatchling E.

 Re: Emydoidea blandingi Question
There is no doubt that these turtles are all most closely related to one another, but it is a classic lump/split decision that could go either way.
Superficially, these turtles appear to be very similar, but the morphological and ecological differences, as well as their distinct geographic distributions suggest an evolutionary trajectory that should be reflected in the taxonomy.
It is likely that a new species or two will be carved from the Emys orbicularis-complex, Actinemys marmorata has two distinct subspecies, and some have suggested that Emydoidea is polytypic (in addition to the fossil species recently described for this genus).

Un pattern bimodale di alimentazione (con picchi la mattina e la sera) è stato appurato per Emydoidea blandingi (Rowe e Moll, 1991); gli animali sono attivi tra le h 5:30 e le h 22:30 e sono stati visti in basking anche dalle h 8:00 alle h 17:30.
Sempre nel genere Clemmys, per C. muhlenbergii, specie a maggiori abitudini acquatiche, Chase e altri (1989) hanno registrato, tra le catture in acqua, una netta prevalenza per zone a profondità inferiore a 10 cm e stretta vicinanza a vegetazione.
Ross e Anderson (1990) riportano per Emydoidea blandingi una varietà di tipi di habitat acquatici utilizzati, aventi sia ampie zone di acqua libera che di vegetazione o altre strutture adatte al riparo.

These studies address the ability of hatchling Blanding’s turtles (Emydoidea blandingii Holbrook, 1838) to overwinter in terrestrial and aquatic environments.
Currently, it is not known where these hatchlings overwinter or how they survive different environmental stresses in each habitat.
In conclusion, although a functional anoxia develops during freezing, the accumulation of lactate does not limit survival.

Michigan Academician: The status of Emydoidea hutchisoni Holman, 1995 (Testudines: Emydidae).
In 1995 I described a new species of turtle, Emydoidea hutchisoni, from the Middle Miocene (Barstovian North American Land Mammal Age [16.0 to 11.5 million EP]) of Nebraska.
Later, in 2002, I identified additional "Emydoidea hutchchisoni" material from the Miocene (Barstovian) of Nebraska and suggested that "Emydoidea hutchisoni" was akinetic (lacked a movable plastron) because of the presence of well developed plastral buttresses and lack of a hinge line in a well-preserved plastron (University of Nebraska State Museum [UNSM] 117938).

 REINTRODUCTION OF HEADSTARTED BLANDING’S TURTLE (EMYDOIDEA BLANDINGII) HATCHLINGS TO THE GRAFTON LAKE WATERSHED, ...
The Grafton Lake watershed in Kejimkujik National Park historically contained a breeding population of Blanding’s turtles (Emydoidea blandingii), but disturbance from dam construction and museum collection in the mid-20th century severely reduced the population.
Hatchling growth in captivity was enhanced by the presence of full spectrum light.  Hatchlings successfully adapted to the natural environment, behaving in such a way to effectively avoid predation, maintain at least 90% body weight, and exhibit normal overwintering behaviour.
The results of this study have enhanced knowledge on appropriate conditions for headstarting and releasing hatchling turtles and improved understanding of hatchling behaviour.

Inframarginals, a series of small scutes lying between the carapacial marginals and the sides of the adjacent plastral scutes, are present in the families Cheloniidae, Chelydridae, Dermatemydidae, and Platysternidae.
Turtles of the genera Pelusios, Emys, Emydoidea, Terrapene, Cuora, Cyclemys, Pyxidea, Notochelys, Pyxis, and Testudo have a transverse hinge, more or less developed on the plastron, and in most species of Kinosternon a pair of hinges borders the abdominals.
These hinges allow the plastron to be folded up to enclose the head and limbs if it is large enough.
