Road Salt Research Paper

Many studies showed that road salt has negative effects on the survival rate of amphibian populations. According to Karraker, N. E., Gibbs, J. P., Vonesh, J. R., they found that large quantities of road salt decreased survival in both Spotted salamanders and Wood frogs. Survival of their embryos also decreased significantly. Amphibians have a lower chance to metamorphose, which is the process of an organism to develop into an adult, causing a lower a survival rate. Sanzo, D., and Hecnar, S. J. (2005, September 12), provided additional evidence of road salt’s effect on amphibian population decline. Their data produced r values of −0.28 and 0.66, proving that amphibian specie richness was negatively correlated with chloride concentration …show more content…
According to Sanzo, D., & Hecnar, S. J. (2005, September 12),they found that road salt can cause sluggishness, loss of balance, physical abnormalities, such as bent tails, reduced weight, reduced fitness, and interfered tadpole’s feeding habits. Many tadpoles struggled while swimming as a result of bent tails, making it harder for those individuals to acquire food. Also, road salt exposure can increases risk of skin dryness, causing respiratory impairment, and prevent growth, which extends the time period for larvaes to develop. (Collins, S. J., Russell, R. W., 2008, August 8). Furthermore, Sanzo, D., & Hecnar, S. J. (2005, September 12), found out that road salt can cause a lack of balance and activity, such as swimming, and decrease the regulation of osmosis, the movement of water through a membrane,. Their data supported the hypothesis that road salt negatively affects communities (Sanzo, D., & Hecnar, S. J., 2005, September 12). Effects of road salts vary between amphibian species. For example, road salt had more negative effects on A. maculatum than R. sylvatica (Karraker, N. E., Gibbs, J. P., Vonesh, J. R., 2008). Also, species such as the Spotted salamander and Wood frog were very sensitive to salinity (Collins, S. J. & Russell, R. W., 2008, August 8), whereas other species such as the American toad (Bufo americanus) and the African clawed frog (Xenopus
