What are two reasons for the demise of the amphibian populations?

These causes include habitat modification and fragmentation, introduced predators or competitors, introduced species, pollution, pesticide use, or over-harvesting. However, many amphibian declines or extinctions have occurred in pristine habitats where the above effects are not likely to occur.Click to see full answer. Beside this, what are the reasons for the change in amphibian populations?The amphibian declines are linked to natural forces such as competition, predation, reproduction and disease, as well as human-induced stresses such as habitat destruction, environmental contamination, invasive species and climate change, researchers said.Secondly, why is a decline in the number of frogs important? The causes for recent amphibian declines are many, but an emerging disease called chytridiomycosis and global climate change are thought the be the biggest threats to amphibians. Chytridiomycosis is a disease caused by the fungal chytrid pathogen Batrachochytrium dendrobatidis. Simply so, what are some reasons amphibian populations may be decreasing? The logical conclusion is that if amphibians populations are in decline, it is likely that habitats in which they live are also degrading. There are numerous known factors that contribute to amphibian declines—habitat destruction, pollution, and newly introduced or invasive species, to name just three.What specific actions are being taken to help declining amphibian populations?Eat organic food. By reducing pesticide and fertilizer use, you directly help in reducing the amount of chemical contamination that affects many amphibian species. Avoid releasing environmental estrogens into the water. Environmental estrogens are known to affect amphibian worldwide including human being.
