Meanwhile, in the ponds and lakes, fewer frogs means fewer tadpoles. These normally play an important role in controlling the growth of algae and also forage on detritus that accumulates as sediment on the bottom. A reduction in the number of tadpoles may lead to an overgrowth of algae, resulting in depletion of oxygen in the water when the ...
All extant (living) amphibians belong to the monophyletic subclass Lissamphibia, with three living orders: Anura (frogs and toads), Urodela (salamanders), and Gymnophiona . Evolved to be mostly semiaquatic , amphibians have adapted to inhabit a wide variety of habitats , with most species living in freshwater , wetland or terrestrial ecosystems ...

Necturus maculosus specimens live in streams, lakes, and ponds in the eastern part of North America. [4] They appear in the southern section of Canada, as far south as Georgia, and from the Midwest United States to North Carolina. Behaviorally, they hide under cover such as rocks and logs during the day and become more active at night. [7]

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 ...
Lakes and ponds experience much of the same pollution as rivers and streams, but are polluted at a quicker rate due to slower moving waters, no water flow outlets, and amount of water. [16] Standing water circulates much less than moving waters, with the deeper water layers only moving during seasonal changes twice a year. [ 16 ]
