Frogs, Toads, Newts and Salamanders Play a Key Role in Ecosystem
May 5-11, 2024 is Amphibian Week. The celebration calls attention to the important role that animals such as frogs, toads, newts and salamanders play in our ecosystem and food chain.
Amphibians consume huge numbers of mosquitoes and other disease-bearing insects. Without amphibians, populations of mosquitoes and other insect pests would likely soar, threatening humans, livestock and plants. Birds and fish that feed on amphibians would also feel the pinch.
Amphibians also serve us medically. Their skin secretions and tissues are used to treat infections, allergies, inflammation and pain. Amphibians are also indicator species, highly sensitive to impacts of climate change climate change Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.
Its name comes from the Greek word amphibios, meaning "to live a double life." An amphibian is a cold-blood animal – it can’t regulate its internal temperature – that can live, as an adult, both on land and in water. It has six other distinctive traits: it has a backbone, favors moist areas, breathes through its skin, fertilizes its eggs outside its body, eats meat, and grows legs when it matures.Frogs, toads, newts and salamanders are all amphibians. So are caecilians – wormlike creatures with poorly developed eyes.
Because they are small and blend into their surroundings, frogs and toads are often easier to hear than see.
