Climate change is emerging as one of the biggest threats to toads & other amphibians. Although a number of causes are responsible for the depletion of toad’s population, but the new study establishes climate change as a major risk for amphibians around the world too. Toad, frog and other amphibians are “overlooked compared to more well-known groups like birds and mammals,” said Kelsey Neam. But losing amphibian’s would be devastating because they often act as a crucial link in the food web of ecosystem, gobbling up insects and in turn, being eaten by larger predators. According to Neam without amphibians we will see the collapse of the food web. Amphibians are the animals that partly live on land and partly on fresh water. In real sense they need both land and water to complete their life cycle. The word ‘amphibian’ is derived from the Greek word “amphibios”, where amphi means dual or both and bios means life. They are the first land vertebrates which arose from the Crossopterygian ancestors in the Devonian period and are perpetuating since Carboniferous to the recent period. They have descended from fish-like ancestors, on one hand and are themselves ancestors of reptiles from which birds and mammals are evolved. Toad is one of the most common amphibia found in Assam. They are the indispensable part of the ecosystem as they are closely associated with many food chain and food web. Even they are directly or indirectly related with human life. They may be considered as an important biological factor by which we can control a number of harmful insect pests. In comparison to their harmful activities they show more useful activities towards human life. But it is observed that due to climate change and different anthropogenic activities their population is declining day by day. To maintain the balance of nature we are to adopt fruitful strategies to stop the devastation of Global Biodiversity
