Most studies on the effect of drought on the biodiversity of freshwater systems have focussed on natural droughts. We sought to assess the effects of artificial drainage on the population dynamics of the European pond turtle (Emys orbicularis). We investigated whether the probability of survival and emigration/immigration was affected by short-term drawdown (for a few months over winter) or long-term habitat drainage (a full year of drying out) in this long-lived species of low dispersal ability.
