|title:||Inventaire des populations du triton crêté (Triturus cristatus Laurenti, 1768), répartition et fréquence des tritons (Caudata, Salamandridae) dans les mares agricoles de la partie française de la Chiers|
|abstract:||Survey of the populations of Triturus cristatus (Laurenti, 1768), distribution and frequency of newts (Caudata, Salamandridae) in agrarian pools in the French part of the Chiers basin. A survey of the newts in 205 agrarian ponds of the French part of the Chiers basin was carried out during the springs of 2009 and 2010 by night-trapping with the aid of keepnets (“triturus trap”). 2021 newts were captured. Te abundance of newt species in inventoried ponds was as follows: Lissotriton helveticus 40%, Ichtyosaura alpestris 30%, Triturus cristatus 18%, Lissotriton vulgaris 12%. This method of survey appeared to be very efficient since Triturus cristatus was discovered in 56 new stations (27,3 % of the ponds studied). This species, which is of patrimonial interest, was formerly known from 7 stations in the study area. Triturus cristatus is wide-spread and abundant in the Lowland of Woëvre. Te discovery of an isolated population close to the French-Belgian border led to a number of conservation actions (creation of new ponds).|
Key words. Amphibia, Triturus cristatus, faunistic survey, Lorraine, Chiers basin.
