Animals are being affected greatly by the decline of biodiversity. Amphibians are have been described as a “marker species or the equivalent of “canaries of the coal mines” meaning they provide an important signal to the health of biodiversity; when they are stressed and struggling, biodiversity may be under pressure. When they are doing well, biodiversity is probably healthy.”
Unfortunately the number of amphibians has been
decreasing drastically. Since frogs have sensitive skin they are usually “the first to respond to environmental changes and their responses can forecast how other species will respond.” Since the number of amphibians are decreasing only time will tell what will happen to other animals when changes of biodiversity become more radical.
Mammals like polar bears and seals will also be greatly affected by changes in biodiversity. Polar bears are depend on sea ice to hunt seals and to move from one area to another, “Polar bears are unlikely to survive as a species if there is an almost complete loss of summer sea-ice cover, which is projected to occur before the end of this century by some climate models. The seals that polar bears hunt are also unlikely to be able to adapt to an absence of summer sea ice, because they give birth to and nurse their pups on the ice and use it as a place for resting.” Caribou and reindeer are also affected by the changes in climate when it comes to finding food and raising their calves.
