Final answer:
Amphibians are highly sensitive to environmental conditions due to their permeable skin, and changes such as increased temperatures, decreased soil moisture, and altered rainfall patterns can disrupt their breeding and development, leading to potential decline or extinction.
Step-by-step explanation:
Increasing temperatures, decreased soil moisture, increased length of the dry seasons, and changes in rainfall patterns are significant stressors for amphibians due to several factors. To begin with, amphibians have permeable skin, making them exceptionally susceptible to changes in their environment, including toxins and pollutants that are readily absorbed. This heightened sensitivity means that changes in temperature and precipitation, which are influenced by climate change, can be particularly harmful.
Amphibians are dependent on specific climatic conditions for breeding and development. The increasing temperature can disrupt the phenology of amphibians, altering the timing of breeding cycles and impacting the availability of water needed for their reproductive habitats. The declining soil moisture and extended dry seasons can lead to habitat desiccation, resulting in a lack of suitable breeding sites and threatening the survival of young amphibians.
Moreover, changes in rainfall patterns can likewise disrupt the delicate balance of ecosystems that amphibians are part of, affecting food availability and the intricate dynamics of the food web. Since amphibians are an integral part of many ecosystems and act as indicators of environmental health, these climatic changes can have cascading effects, leading possibly to the decline or extinction of amphibian populations and subsequently impacting entire ecosystems.
