Road mortality threatens small northern populations of the European pond turtle, Emys orbicularis

Giedrius Trakimas & Jonas Sidaravičius
Little is known about road mortality and the effects to European pond turtle Emys orbicularis populations at the northern border of its range. Survival of the turtle populations in suboptimal conditions depends heavily on longevity, regular annual breeding and relatively large clutch sizes, but additional unnatural mortality could alter their survival rates. Loss of only single turtle in majority of northern populations could mean a loss of 3-20% of subpopulation. But due to comparative rarity...
