The Declining of the Amphibian Population
...he declining rate of the amphibians. The stratospheric ozone being depleted may harm the amphibian species. The dwindling ozone layer is a danger to the amphibians that lay their eggs out in the open. The developing embryos DNA can become damaged by the radiation. The egg loss may have led to the decline in the population of the amphibians. An experimentthat a group of students led in Oregon in 1979. They examineed various aspects of life for several species of amphibians. they monitored the amphibians from the embryonic stage through the tadpole stage and into adulthood. The team had massive die-offs of fertilized eggs from the Cascades frogs and the Western toad. The researchers ruled out the possibility that the chemistry of the water where the animals were laying their eggs into the same lake water with eggs that have been left behind, had perished. The embryonic frogs and toads developed and hatched normally in the lab. Another cause of the amphibian's populations decling is the destruction of their natural habitat. Even changing their hahitat can harm the amphibian's. there was a survey taken in western...
