Urbanization and disease in amphibians
Urbanization and disease in amphibians
Amphibians depend on freshwater wetlands that have greatly been altered by urbanization. Increases in human density can be linked to changes in light and thermal environments, water chemistry, and hydrology. These characteristic shifts provide a changing backdrop for the infection of amphibian hosts by macroparasites such as trematodes. Comparative and experimental approaches show how changes in the environmental context influence patterns of infection in wild amphibian populations. The patters of infection of amphibians collected from sixty wetlands located in underdeveloped, suburban, and urban environments are compared. Results show that the environmental context is a critical driver of infection patterns in wild amphibians, and that urbanization may alter the dynamics of disease in wildlife populations.
