Environmental stress source not only degrades the habitats and deteriorates morphological and physiological aspects of amphibians, but also is an important stress factor that may affect communication and behavior. Amphibians “indicate” the health status of the ecosystems where they occur (Saber et al. 2017). Some authors, like Scott and Sloman (2004), coined the term “ecological death” to refer to those aquatic organisms that no longer play an environmental role or provide an environmental service, or to those that “sacrifice” a biological function to offset the damage or environmental stress. In this sense, through field records, León et al. (2019) demonstrated that males of S. nasicus shift their vocal structure in acoustically disturbed sites, mainly by making vocal “adjustments” in their frequencies and amplitudes to counteract the effect of noise maSking. This has sublethal effects on the reproductive success, clutch size, survival of individuals and populations viability highlighting of how is important to stop the collapse of aquatic ecosystems.
