Amphibian Population Decrease, 200 Times Faster


Amphibian Population

The new study in the United States (U.S.) found a decline in amphibian populations of the world. The experts were working hard to find the cause of this decline.

Although the study published in the journal Annals of the New York Academy of Sciences that states there is no certainty that the cause of decline in amphibian populations. Experts suspect, a decrease related to natural causes, including competition between animals, mutual predation, and reproduction.

In addition, experts also expect a decrease related to humans, such as habitat destruction, environmental contamination and climate change. "Many changes occur within the last 100 years," said Professor Andrew Blaustein of Oregon State University.

"We realized a decrease was not caused by one thing only, but a lot of things, he added. Currently, mammals, fish and birds have not felt the impact as in amphibians, she added. Currently, amphibians disappearing 200 times faster than the average normal extinction , "he said.

As quoted by UPI, natural selection pressures, especially related to human activity makes amphibious difficulty adapting because of the changes that happen too fast.
