Amphibian ecology studies the relationships between amphibians and their environment. Amphibians, such as frogs, toads, and salamanders, typically live both in water and on land, which makes them sensitive to changes in their habitats. They play crucial roles in ecosystems, serving as both predators and prey, and help control insect populations. Amphibians also contribute to nutrient cycling in ecosystems. Their permeable skin allows for gas exchange and moisture absorption, making them indicators of environmental health. Changes in amphibian populations can signal shifts in ecosystem conditions, often due to factors like pollution, habitat loss, and climate change.
