Ciries represent a unique ecosystem dominated by humans and highdensity man-made infrastructure,associated with modifications or entire loss of local ***,urbanization constitutes a consid-erable challenge for wildlife,and only a minority of species is able to persist in cities(Niemela et al.2011).Species that maintain popula-tions in cities are usually characterized by significant changes in life history characteristics,population structure,and ecological relations(Niemela et al.2011).

Batesian mimicry is the process in which harmless species adopt the appearance of a dangerous, aposematic *** some prey species,both Batesian mimetic and non-Batesian morphs coexist,presupposing that both morphs have to be evolutionarily *** viperine snake, natrix maura,exhibits a zigzag dorsal pattern and antipredatory behavior that mimics European *** snake also has a striped dorsal pattern that coexists with the zigzag *** have examined whether individuals belonging to different geographically structured clades were more likely to exhibit a certain dorsal pattern,and whether the zigzag pattern has a protective function by exposing artificial snakes to predation in natural environments,in addition to comparing antipredatory behavior between zigzag and striped snakes also in natural *** results indicate that the striped pattern was not geographically structured,but *** predators less frequently attacked zigzag plasticine models than striped or unpatterned *** detected a shift in antipredator behavior between the 2 morphs,as Batesian mimicking *** responded to an approaching potential predator by remaining immobile or fleeing at shorter distances than did striped *** conclude that Batesian mimics maintain the cryptic and aposematic value by resembling vipers,whereas in open habitats the non-Batesian mimic has altered its antipredator behavior to maintain its fitness.
