It is crucial for most amphibians to maintain a high level of genetic variation through large and more diverse environments. Education of local people to protect amphibians is crucial, along with legislation for local protection and limiting the use of toxic chemicals, including some fertilizers and pesticides in sensitive amphibian areas.

Amphibians, particularly anurans (frogs and toads), are increasingly used as bioindicators of contaminant accumulation in pollution studies. [27] Anurans absorb toxic chemicals through their skin and their larval gill membranes and are sensitive to alterations in their environment. [28]
Running water is a type of freshwater habitat that mainly consists of rivers and streams. Running, fast-moving waters have a higher oxygen content, allowing different species to thrive and making pollution easier to combat. [6] Running water is an open system, meaning it is not isolate and exchanges matter and energy with other systems. [6]
Amphibians are in decline worldwide, with 2 out of every 5 species threatened by extinction, according to a paper published Wednesday in the scientific journal Nature. More than 2,000 species of ...
Water body temperature is one of the most ubiquitous variables collected in aquatic biomonitoring. Temperatures at the water surface, through the water column, and in the lowest levels of the water body (benthic zone) can all provide insight into different aspects of an aquatic ecosystem. Water temperature is directly affected by climate change ...
The eggs of amphibians are typically laid in water and hatch into free-living larvae that complete their development in water and later transform into either aquatic or terrestrial adults. In many species of frog and in most lungless salamanders (Plethodontidae), direct development takes place, the larvae growing within the eggs and emerging as ...
Acidification, eutrophication, and other forms of water pollution negatively affect the aquatic habitats of moor frogs. [42] Moor frogs normally enjoy acidic environments; however, peat bogs which produce these acidic conditions have poor buffering properties that make them susceptible to drastic decreases of pH even below 4.5.
Additionally 1193 amphibian species (16% of those evaluated) are listed as data deficient, meaning there is insufficient information for a full assessment of conservation status. As these species typically have small distributions and/or populations, they are intrinsically likely to be threatened, according to the IUCN. [ 2 ]
