The Habitats, Life Cycle and Physiological Adaptation of Green Toad (Pseudepidalea viridis) in Northern Israel

Gad Degani

Abstract :

 Green toads (Pseudepidalea viridis) (synonym Bufo viridis) are distributed throughout Israel from the north in the Upper Galilee, the Golan Heights, and the southern coastal plain including the desert area. The present study described the life cycle and physiological adaptation of green toads to semi–arid habitats in northern Israel. The eeding places are mainly ponds where water is immovable or has a very low flow, and is available in very high variability from one month to all year round. The ability to use various water bodies is one of the ways green toads adapt to terrestrial life. The main adaptation phenomenon of green toads is explained by the large geographical distribution described in this paper involving a large number of eggs, short periods of tadpole growth, complete metamorphosis in the eeding places, physiological adaptation to water loss, and high plasma concentration through urea accumulations of the toads in the terrestrial phase. The proposed model explained the adaptation of green toads to various habitats, and its large distribution was represented to summarize its main adaptation character
