摘要: Abstract The high frequency of various kinds phenotypic abnormalities in some local amphibian populations has long been a puzzle. In this paper, we report malformations the two species frogs, Pelophylax saharicus and Discoglossus pictus, inhabiting water bodies created by an artificial dam area devoted to intensive agriculture northeastern part Tunisia. More than 35% recently metamorphosed young froglets P. saharicus, 25% D. display morphological that can be distributed 18 types involving limbs, spine, eyes, or skin. Although did not investigate cause these malformations, unusually malformation rate (33.3%) populations, as compared conspecific individuals from other, noncultivated areas, points environmental disturbance.
