what is the impact of the quality of air and water on the domestic birds of Sikkim.
Answers
Explanation:
Climate change is one of the greatest challenges faced by the current world. With the current rate of green house gas emission the global temperature is likely to increase by 1.5 to 4.5°C by 2100. Such increase in temperature has affected climate pattern causing cascading effect on biotic and abiotic components of the ecosystem. Warming rate, and also the consequences, is higher in the Himalayas than the rest of the world. Sikkim occupies an important biogeographic location in the entire Himalayan chain and represents high diversity of life forms. Over the years various climate induced effects have been felt in the Sikkim Himalayas. In this chapter, we provide some evidences of climate change effect on four important faunal groups namely, birds, reptiles, amphibians and butterflies. In response to climate change, many species of birds, reptiles, amphibians and butterflies have extended or shifted their ranges upwards along the elevation gradient in Sikkim. Late breeding or breeding failure among birds and early breeding of amphibians have been observed in recent years. Biased sex ratio towards females (higher temperature favors females) has been observed in snakes. Drying springs and erratic rainfall pattern has severely affected breeding of amphibians causing decline in amphibian population. Long dry spells have caused the disappearance of turtles from Sikkim. Based on our observations in Sikkim, and many other studies elsewhere, we opined that there is severe effect of climate change on Sikkim fauna which might lead to serious consequences resulting in extinction of species. We recommend long term monitoring and detailed studies to understand such effects and consequences so that mitigation measures could be undertaken.
