Figure 1. Frogs were collected from 3 in A procedure for taxon assessment based on morphological variation in European water frogs (Pelophylax esculentus complex)

Figure 1. Frogs were collected from 3 different localities in South Banat, Serbia: 1) Stevanove ravnice, within the Special Nature Reserve "Deliblatska peščara" (44°49′57.8″N 21°18′33.1″E, 44°50′14.3″N 21°18′14.0″E), 2) Canal Banatska Palanka – Novi Becej (44°51′14.4″N 21°18′17.8″E).; 3) Canal Jaruga in the peripheral zone of the protected natural landscape "Karaš-Nera" (44°52′30.8″N 21°28′16.0″E).
