Global Amphibian Decline What Humans do to decrease BioDiversity in General Habitat change Invasive species Climate change Over-exploitation Pollution What’s an amphibian • • • • 4 digits on front legs Breathes through lungs and skin as adult Smooth, moist skin Frogs, skinks, salamanders Why Amphibians are important: • Bioindicators (tell us about water and land ecosystems) • Have medicinal value (antibiotics, painkillers, anti-fungus) Role in ecosystem • Predators and Prey They are a true representation of BioDiversity So what’s the Problem? • They are disappearing!!!!!!!! • More than 600 species have gone etinct within the last decade. • A third of existing amphibian species are in trouble (vulnerable or endangered status).
