Mortality
Climate has an effect on the survival of Emys orbicularis hatchlings. Hatchlings are only able to survive under favorable weather conditions, but due to regular annual clutch sizes and long lifespan, Emys orbicularis adults, along with many freshwater turtles, balance out loss of hatchlings due to climate.
Emys orbicularis species have become rare in most countries even though they are widely distributed in Europe. The building of roads and driving of cars through natural habitats of Emys is a possible factor that threatens the populations of the European pond turtle. Road networks and traffic often carry complex ecological effects to animal populations such as fragmenting natural habitats and creating barriers for animal movement. Mortality on the road is most likely due to females selecting nests near roads which places a potential danger for the hatchlings as well. Hatchlings that wander too closely to roads are more likely to be killed and put the future population in danger. Although the possibility of roads being a major causation for the mortality of Emys orbicularis turtles is a rare phenomenon, long-term monitoring is necessary. Life span is 40–60 years. They can live over 100 years but it is very rare and unusual.

Famous quotes containing the word mortality:
“When I turned into a parent, I experienced a real and total personality change that slowly shifted back to the “normal” me, yet has not completely vanished. I believe the two levels are now superimposed, with an additional sprinkling of mortality intimations.”
—Sonia Taitz (20th century)
“The mortality of all inanimate things is terrible to me, but that of books most of all.”
—William Dean Howells (1837–1920)
